2022-02-23 China Titanium Dioxide Industry Association Pre-submit "Titanium Dioxide Tax Relief Report for Chlorination Process" In order to report to the relevant state authorities on the report [Application for Tax Relief and Tax Reduction of Chlorinated Titanium Dioxide", on May 20th, an application report seminar was held in Beijing for four chlorinated production enterprises in the country. The chlorination titanium dioxide index and production cost were analyzed. Under the guidance and guidance of the Secretary-General of the China Titanium Dioxide Industry Association, Mr. Yang Yuande, we put forward a number of reasonable application reports, which will be submitted by the Secretariat of the China Titanium Dioxide Industry Association to the relevant supervisors. The industrial production of titanium dioxide in China's chlorination process began in the late 1950s and has undergone three stages of development: an independent Pigment And Dye R&D, Pvc Resin technology introduction, and digestion innovation phase. In 2015, it began its industrialization phase. At present, China's chlorination titanium dioxide production lines are: Jinzhou Titanium Industry, Henan Lili Union, Yunnan Xinli, Henan Luohe Xingmao. Due to the difficulty of the chlorination production technology, the large investment in imported technology, and the long production period of the test vehicle, the development of the chlorination process titanium dioxide industry has been greatly restricted. National policy has been chlorinated Titanium Dioxide Rutile as an encouragement product since 2007. Due to Ethylene-Vinyl Acetate historical reasons, it has not given many encouragement policies in its implementation process, especially in terms of exports. In order to further optimize the structure of export commodities in 2007, the Exports of [high energy-consuming and high-polluting" products, the Ministry of Finance and the State Administration of Taxation, the National Development and Reform Commission, the Ministry of Commerce, and the General Administration of Customs issued the [Noti

2022-02-22 What is pvc material pvc decoration materials Whether it is home life or office supplies, products made of PVC materials are almost everywhere. So what is pvc material ? Pvc decoration materials which? Don't worry, here's a look at Xiaobian. What is pvc material Pvc Resin is a kind of plastic decorative material. Its chemical name is polyvinyl chloride. The polyvinyl chloride (PVC) color is slightly yellow translucent and shiny. The transparency is better than that of polyethylene and polypropylene, and worse than that of polystyrene. It is divided into soft and rigid polyvinyl chloride, and the soft products are soft and tough, and the stickiness of the hand is higher than that of the low density polyethylene. Less than polypropylene, whitening occurs at the inflection point. PVC is an amorphous white powder with a low degree of branching. Industrial production of PVC molecular weight is generally in the range of 50,000 to 120,000, with a large polydispersity, molecular weight increases with the decrease of Ethylene-Vinyl Acetate polymerization temperature; no fixed melting point, 80 ~ 85 °C began to soften, 130 °C became viscoelastic state , 160 ~ 180 °C began to change into a viscous flow state; has good mechanical properties, tensile strength of about 60MPa, impact strength 5 ~ 10kJ/m2; has excellent dielectric properties. However, the stability to light and heat is poor. When the temperature is over 100°C or exposed to sunlight for a long time, it will decompose to produce hydrogen chloride, and further autocatalytic decomposition will cause discoloration. The physical and mechanical properties will also rapidly decline. In practice, it must be added to the stability. Agent to improve the stability to heat and light. PVC is very hard and has poor solubility. It can only dissolve in a few solvents such as cyclohexanone, dichloroethane and tetra

2022-02-18 PVC and non-PVC infusion bag thermal transfer film has been successfully developed PVC and non-PVC infusion bag special heat transfer film has been successfully developed by Zhuo Li Hot Stamping Materials Co., Ltd., Jiaozuo City, Henan Province, which ended the history of China's plastic infusion bag thermal transfer film relying on imports, and filled the domestic gap. Experts believe that the successful development of this product has enabled China's non-PVC infusion bags to be completely domesticated from film making to bagging and filling, which will greatly promote the process of applying plastic soft bags to infusion products. According to statistics, in recent years, the market demand for domestic thermal transfer film has reached 14.2 million square meters, and only Baxter's factory usage in Pvc Resin China has reached 6 million square meters. It is estimated that by 2008, the domestic market demand for thermal transfer film will reach 470 million square meters, and the global demand will reach 12 billion square meters. Due to strict medical material standards, such special consumables have always been imported and the price is still high. The cost of soft plastic infusion bags is difficult to reduce, which is not conducive to the popularization and application of soft plastic infusion bags. Jiaozuo City, Henan Zhuoli Hot Stamping Materials Co., Ltd. organized elite technical personnel, after a year of hard work, and finally overcame the main technical difficulties of medical thermal transfer film. The project was approved by the Science and Technology Department of Henan Province in June 2005 and was appraised by the Science and Technology Rubber And Plastic Bureau of Jiaozuo City. The appraisal opinion stated that Jiaozuo City Zhuoli Co., Ltd. adopted a heat transfer film production technology researched and developed on projects such as base selection, raw material screening, heat-sensitive ink formulation optimization, coating process, etc. The formula was reasonable and the process was feas

2022-02-18 From late July to late July, the price of PVC in China ended down, began to stabilise and rebounded slightly, which shows that --- PVC market ushered in a new round of small climax Until the end of last week, East and South China calcium carbide method PVC prices are in 7300 yuan (t price, the same below) above, the highest offer of 7,500 yuan; ethylene law is also around 7,500 yuan, the highest offer 7600 yuan. Although the transaction volume is not very large, the price is still relatively strong, rising gradually and ending the decline for several months. The main factors for the new round of price increase are as follows: The first is the national price increase of calcium carbide. As Inner Mongolia's electricity Pvc Resin price is increased by 0.0157 yuan/kWh, and since June 1 this year, the electricity tariff has been Rubber And Plastic used to make up the difference. This has directly stimulated the rise in the price of calcium carbide in Inner Mongolia, which has been unsustainable. This has led to a gradual decline in the calcium carbide market, which has long been depressed in the northwest. rising. The sudden increase in the price of calcium carbide made PVC manufacturers unpredictable and the supply of goods was once tight, which further stimulated the continued rise in the price of calcium carbide. Since the beginning of the northwest, the price of calcium carbide has gradually increased to the entire country. The price of calcium carbide in other regions of the country has also been adjusted upwards, which has formed a national wind-induced Pvc Price rise of calcium carbide. The rise in the price of calcium carbide has increased the cost of PVC, which Titanium Dioxide has prompted the PVC market, which has been experiencing a long period of softness, to begin to pick up. The second is that crude oil prices have hit new highs. The current crude oil price is already above US$66/barrel, and the price still has an upward trend. It has been predicted that it will break through US$70/barrel

2022-02-17 The domestic melamine market mainly depends on the rise and fall of the real estate market [At present, the ex-factory price of melamine is only 8,300 yuan (ton price, the same below), which has dropped by 2200 yuan year-on-year. Calculating the current urea price, the company will lose at least 500 yuan per metric ton of melamine." May 21, Henan Zhongyuan Guo Quanpu, general manager of Dahua Group Sales Company, said to reporters with anxiety. According to Guo Quanpu introduction, although the domestic urea market has come out of the rally in volume and price before the beginning of May this year, the highest ex-factory Mlemine Powder price has exceeded 2,500 yuan, but it did not drive melamine prices higher. On the contrary, domestic melamine prices have remained low this year despite pressure from unfavorable factors such as blocked exports, overcapacity, and shrinking downstream demand. In early March, it even hit a new low in recent years. Among them, the high-pressure method melamine ex-factory price once touched a bottom of 7,800 yuan, and the atmospheric pressure method fell below 7,500 yuan. As a result, production cuts and production cuts have rapidly increased, and the industry's operating rate has dropped below 40%. After oscillating and digesting inventory in the past two months, the price of melamine stabilized and recovered after the price of urea continued to rise. However, the current price is still lower than the average cost of the industry, and the overall operating rate is still only 50%. For the later trend of the melamine market, Guo Quanpu believes that he is not very optimistic, and it is difficult to change. It is difficult to effectively amplify domestic demand Domestic melamine is mainly used for the processing of laminates, coatings, paper, textiles, leather and molding compounds. Among them, laminates are the largest consumer of melamine, and its consumption of melamine accounts for more than 50% of total domestic consumption. The demand for laminates depends on the rise and fall of the real es

2022-02-17 PET (resin) basics Basic knowledge of Pet Resin PET (also known as PETE) is a polyester material that can be drawn, injection molded, and blown. According to different requirements, special grades of resin can have different Rubber And Plastic applications. PET is a long chain (long chain of molecules is shown by the number of basic units), a white or slightly blue thermoplastic plastic, made of polycondensation of terephthalic acid and ethylene glycol. Each of these raw material particles provided by the resin manufacturer is about 0.05 g. PET was an important textile material in the 1950s. Good mechanical strength, temperature resistance and abrasion resistance make PET an ideal material to replace naturally produced silk, cotton and wool. PET also has good barrier properties, low water absorption and good toughness. The tensile strength of the PET film is similar to that of an aluminum sheet and is three times that of a PA and PC film. The PET film is transparent, and if it is stretched qualitatively, its sheet tensile strength can reach 1/3 to 1/2 of the steel sheet. He is the toughest thermoplastic film. It burns intensely with a yellow flame when there is an open flame, and it can continue to burn after leaving the fire. Bottle grade PET Today, Pet Resin Iv 0.8 is still widely used in these areas, but since the 1970s, the market needed a lightweight, easily broken bottle to package gas-containing beverages. PET has become the best choice. Unlike simple polymers such as PE, PET is not manufactured in a single process, but rather is derived from the chemical reaction of pure terephthalic acid and ethylene glycol. In the past, the supply of PET was designated as the first to be practical, resulting in new production capacity to be put into production this year, ensuring that PET will continue to grow in the future. The related polyesters are PEN (polyethylene naphthalate) and PBT (polybutylene terephthalate, whi

2022-02-16 PVC steel pipe is what PVC steel pipe manufacturers What is pvc steel pipe? Pvc steel pipe is a new type of pvc reinforced material, which has a very good improvement in compressive strength and hardness. With the increasing demand for steel pipe, the production of steel pipe is also increasing. China's steel pipe manufacturers are spread all over the country and competition is fierce. Each factory has played different brands and the types of production vary. Let us work together to understand the PVC steel pipe manufacturers, will also help later purchase. What is pvc steel pipe? Pvc Pipe is also what we often say pvc wire reinforced pipe, the pipe is a three-tier structure, both inside and outside the pvc soft plastic, the middle layer is a steel wire reinforced structure, or steel mesh or spiral wire, so its formation The pipe will also have a number of titles: pvc steel pipe, pvc wire reinforced pipe, pvc wire spiral reinforced pipe, pvc wire mesh reinforced hose, pvc wire mesh hose and so on. In fact, it is the internal increase of the reinforcing steel wire layer, which causes the Pvc Resin to undergo a certain change in strength, resistance to distortion, quality, etc., or to modify or strengthen the PVC tube. Pvc steel pipe is a new type of pvc reinforced material, which has a very good improvement in compressive strength and hardness. In the steel pipe, there are multiple production methods, among which the main types of steel pipe in the market are high-pressure steel pipe, low-pressure steel pipe, steel wire frame pipe, and transparent Rubber And Plastic steel pipe, which are used in different environments. The pvc steel pipe is now the most widely used product. Pvc steel pipe main purpose PVC steel wire pipe can be divided into industrial grade (specialized for transporting industrial water, oil, sewage, powder, chemical raw materials, etc.) and food grade (food

2022-02-16 Short-term Domestic Titanium Dioxide Market Stable and Weak Trend The recent trend of raw material titanium concentrate is stable and has little impact on the market. However, the downstream is gradually weakening, and the demand is weak. Some of the companies are profit-making sales, and the bearish market is expected to become stronger. Market supply and demand side: The domestic mainstream titanium dioxide enterprise plant started to reduce compared with the previous period, and the overall supply has been reduced. Terminal downstream Pigment And Dye companies get goods on demand, and some of the downstream more than adequate inventory, demand is not endangered, the current corporate exports are relatively stable, no significant changes. Prediction: In the short-term market, the raw material Titanium Dioxide concentrate runs sideways and has limited impact on the market. The main influence is mostly from the demand side. With the arrival of the off-season and the downstream companies having more inventory in the early period, the procurement enthusiasm is weakened, and the Titanium Dioxide Anatase business sales pressure As a result, some of the companies are selling profit-oriented sales, and the focus of market negotiations has Melamine Powder declined from the Sodium Hexametaphosphate previous period. The short-term domestic market for titanium dioxide is expected to stabilize and weaken.

2022-02-15 U.S. announces the launch of a new PET resin dryer Maguire Asia has announced the introduction of an innovative drying system that uses a newly designed wheel dryer and a unique airflow layout that not only saves space for Pet Resin processors, reduces maintenance costs and energy consumption, but also The adjustment of the feed rate and characteristics of the material to be dried is adjusted adaptively to ensure the consistency of the performance. It is reported that the footprint of the new Intelli Pet Chips drying system is only 55% to 60% of the same wheeled PET drying system, and its energy consumption is 40% to 50% lower than that of the conventional double-dehumidified bed drying system. The system adopts automatic temperature and speed control device, which can automatically Rubber And Plastic adjust according to the change of the drying amount, moisture content and material temperature, so as to ensure that the temperature of the resin when leaving the hopper outlet is constant and the consistency of the product is ensured, without intervention of the operator. Key components of the Intelli PET system include: a dehumidification wheel dryer similar to the Mage Nova dryer, a two-zone drying hopper, an electric heater or a gas heater with up to 90% of heat, a cyclone Separator, an optional self-cleaning "pulse" dust collector. In contrast, similar wheeled PET dryers have one more drying circuit centered on the hot air dryer. In addition, there are two cyclone separators and two dust collectors (requires regular updating of the dustbags). Two low-efficiency gas heaters. Dryer The Intelli PET drying system is efficient and simple in structure. One of the key factors is recycling the heat from the return air from the hopper Pvc Resin back to the dryer. The air enters the blower after being filtered in the dryer. After passing through the blower, it is divided into two channels and approac

2022-02-15 Is melamine sheet toxic? What are the advantages and disadvantages of melamine sheet? In recent years, with the improvement of economic level, people's demands for decoration have become more and more elaborate. We must know that if we live in a good environment, we can bring good mood to you. We must know that a good environment can Said to be the most important in the renovation. The following Xiao Bian will introduce to you the melamine sheet toxic and what are the advantages and disadvantages of melamine sheet. Is melamine sheet toxic? Is melamine sheet toxic? In general, it can be said that the Melamine Powder board is not poisonous. You can use it safely, but be aware that if there are some boards that do not meet the quality standard, then the board is also toxic because The chemical released by melamine plates is mainly formaldehyde. Everyone knows that formaldehyde is toxic, and it also causes great harm to the human body. This melamine plate is not only smooth in surface, but it is still an affordable product. Generally speaking, its reference price is 50 to 70 per square meter, and melamine on the market also meets the national standard. However, the accumulation of a variety of furniture is likely to cause excessive formaldehyde in the house after renovation. Therefore, it is advisable to keep the house ventilated for several months after the renovation. Only in this way can the harmful gases in the air reach the national standard and then stay. What are the advantages and disadvantages of melamine board 1, advantages Decoration function: There is a layer of melamine paper on the surface of the cyanide board, and the texture or color of the paper can be controlled by human. It has a variety of patterns, bright color and luster, Melamine 99.5% and it is also a kind of decorative comparison. Strong materials, if used to install it, can also play some embellishment Rubber And Plasti

2022-02-14 Vinyl acetate monomer supply tight, manufacturers take the opportunity to increase the price of new devices to step up construction According to a new research report from SRI Consulting, as the demand for the market has grown, the operating rate of global vinyl acetate monomer (VAM) devices has risen to 85% from 83% two years ago. Demand for VAM is still strong this year, but due to insufficient supply of acetic acid raw materials, the VAM plant operating rate has been limited, resulting in lower inventory levels. In this case, North American producers took the opportunity to raise prices by 7% to 8%, Rubber And Plastic and some producers are seeking opportunities to raise prices again. Analysts said that in the next few years, the global VAM market looks promising. Experts predict that the global VAM Eva Resin market demand before 2009 is expected to grow at an average annual rate of 2.9% to 3.2%. As most of the consumption areas are relatively mature, the fastest growing demand for VAM in the next five years will be ethylene-vinyl alcohol copolymer resin (EVOH), which is expected to increase at an average annual rate of 7%, but this will not generate too much demand for VAM. Big impact because EVOH accounts for less than 6% of total VAM demand. As the market supply has shown signs of tightening, some manufacturers have planned to expand VAM in the coming years. Celanese has recently agreed to acquire Acetex, a world-famous acetic acid producer, Eva Granlues and will continue to promote 275,000 tons/year of the Acetate-based complex jointly invested by Saudi National Petrochemical Industry Company in Saudi Al Jubail. Year VAM device project. The Ethylene-Vinyl Acetate acquisition is currently undergoing an antitrust investigation by the EU Executive Committee. Dalian Chemical Industry Co., Ltd., located in Taipei, China, also built a 350,000-ton/year VAM production facility in Maitai, Taiwan, China. It is expected to Pvc Resin b

2022-02-14 Titanium dioxide "bull market" has ended? Recently, the market price of Titanium Dioxide in China has continued to decline for the first time in more than one year. On June 8, the average price of rutile titanium dioxide in East China has returned to about 18,450 yuan/ton, which is close to the decrease of 19,400 yuan/ton on May 20. 1000 yuan / ton, which part of the company's product Pigment And Dye market prices have fallen more than 2,000 yuan / ton, whether it means that this round of the "bull market" has ended? After the market price of titanium dioxide in China reached the end of 2015 at the end of the year, the market generally agreed that this is a reasonable rebound cycle and is a normal reflection of the return of value and market leverage. However, no one expected the titanium dioxide market to change from a rebound to a reversal, and then went out of a wave of [mad cow" prices. Typical prices of products such as rutile titanium dioxide in eastern China rose from 9,800 yuan/ton in early December 2015 to In late May of 2017, the price of 19,400 yuan/ton, the price per ton of product rose within 18 months to nearly 10,000 yuan, and the corresponding price of 19,400 yuan/ton last appeared in mid-June 2012, the last round The decline took 42 months. Some industry observers believe that titanium dioxide companies have frequently adjusted their prices in the past year or more, and the time and amount of price increases for each round have been surprisingly coincidental. This should be the result of tacitly agreed price hikes among large companies. The effect of implementation in 2016 is very obvious. Thus, when price increases have become a habit, then there are Titanium Dioxide Rutile gradually regular rules. Since 2017, the industry has basically summed up two rules for the market price increase of titanium dioxide: First, the boss leads, and everyone keeps up; second, it starts once a

2022-02-11 PVC pipe is toxic? What is the price of pvc pipe? PVC pipe is toxic? What is the price of pvc pipe? PVC pipe (UPVC pipe) hard PVC pipe is made of polyvinyl chloride resin and stabilizer, lubricant and so on. It is extruded by hot pressing method. It is the first plastic pipe that has been developed and applied. UPVC pipe has strong corrosion resistance, easy adhesion, low price and hard texture. However, due to the oozing of UPVC monomer and additives, it is only suitable for water supply systems with a delivery temperature not exceeding 45 °C. Plastic pipes are used to transport drinking water, wastewater, chemicals, heating fluids and coolants, food, ultrapure liquids, slurries, gases, Pvc Resin compressed air and vacuum systems. The staff of the National Plastic Products Quality Supervision and Inspection Center said that users who use PVC water pipes in China are still more common. PVC water pipes and PVC cling film have nothing to do with them. They are qualified for the inspection of PVC water pipes. There is no toxic phenomenon of water pipes. Residents can use PVC pipes with confidence. However, some experts said that PVC pipes are not necessarily all toxic. The qualified PVC itself is safe Rubber And Plastic and non-toxic, and has the advantages of energy saving, impact strength, chemical corrosion resistance and flame retardancy, which can be reduced to minus 30 degrees Celsius. It is recommended for use by the Ministry of Construction in the temperature environment of 70 degrees Celsius. PVC will be added to the stabilizer during production, but the stabilizer is non-toxic and toxic. Only when a toxic stabilizer such as lead salt is added will it cause hidden dangers. However, PVC products are mixed, and some small enterprises use lead salts as stabilizers, and it is difficult to meet relevant health standards. When consumers choose PVC materials, it is best to purchase them in the building materials market with formal and credible quality as

2022-02-11 Analysis of the application of plasticizer DOP in soft PVC and PVC/ABS blends Pvc Resin has the advantages of flame retardancy, wear resistance and chemical resistance. Polyvinyl chloride and its alloy products can be classified into hard products and soft products according to the amount of plasticizer added. Soft products add a certain amount of plasticizer to the polymer, reduce the force between the polymer molecules, increase the mobility of the molecular chain, reduce the glass transition temperature, and improve the low temperature processing performance. DOP is one of the main plasticizers for soft PVC products . Due to the excellent characteristics of PVC, such as high impact resistance, heat resistance, dimensional stability and easy processing and forming, the use of aBS for PVC blending modification Rubber And Plastic can not only improve the processing properties of PVC, but also significantly Improve the mechanical properties of PVC so that the impact strength of aBS/PVC blends exceeds that of pure aBS and PVC [2, 4]. PVC/aBS blends are an important modified plastic. This experiment comprehensively analyzed the effect of DOP on the mechanical properties and hardness of pure PVC and PVC/aBS blends. 1 experimental part 1.1 Experimental materials Polyvinyl chloride (PVC), SG-3, SG-5, Xinjiang Petrochemical Company; acrylonitrile/butadiene/styrene copolymer (aBS), Pa-747S, Taiwan Chimei Chemical Company; dioctyl phthalate (DOP), industrial grade,Sodium Hexametaphosphate commercially available; stabilizers, processing aids, etc. are domestic industrial grade. 1.2 Experimental instruments and equipment Two-roller refining machine, SK-160B, Shanghai Rubber Machinery Factory; electronic tensile testing machine, aI-7000M, high-speed rail technology company rubber hardness tester, Shaw a, Shanghai Xianfeng Film Machinery Factory. 1.3 Experimental techniques and

2022-02-10 Industry Jingwei PVC paste resin: development space at the high end Pvc Paste Resin is widely used in artificial leather, wallpaper, ink, adhesives and many other fields. After rapid development in recent years in China, the annual productivity of the PVC paste resin industry has grown rapidly. It is expected that in 2005, domestic production will reach 220,000 tons. However, at the same time as rapid development, some issues must be seriously addressed as soon as possible. Market competition pressure In 2004, the total production capacity of domestic PVC paste resin was 270,000 tons, the output was about 208,000 tons, and the sales volume was about 206,000 tons. The domestic PVC paste resin market demand is expected to exceed 300,000 tons in 2010. Although the PVC paste resin Pvc P440 market in China is Rubber And Plastic developing rapidly, the fierce market competition is fierce. Mainly in: The first is the acceleration of energy expansion. According to statistics, during the three years from 2001 to 2003, the domestic PVC paste resin production capacity was 162,000 tons, 177,000 tons and 200,000 tons, respectively, an increase of 1.8%, 9.2%, and 12.9%, respectively. With the completion of the expansion project of several PVC paste resin installations for chlor-alkali and Shenyang Chemicals in Shanghai, this year's national production capacity may exceed 300,000 tons. The second is that the quality of products is still not satisfactory. Although China has introduced PVC paste resin production technology, there is still a certain gap compared with the world's advanced level. In particular, domestic repeated production of the same brand, the production method is relatively lagging, the production process is too single, coupled with the lack of stability of individual product quality, leading to a large number of domestic PVC paste resin backlog, on the other hand, a large number of foreign special resin influx into the countr

2022-02-10 Annual output of one million tons of PVC resin project started construction The first-phase project of annual output of 1 million tons of Pvc Resin and supporting annual output of 720,000 tons of ion-exchange membrane caustic soda project by Sichuan Hanlong Group and Baotou Menghan Industrial Co., Ltd. was jointly invested in Baotou City, Inner Mongolia Autonomous Region on September 26. The Murter Right Banner started construction. It is understood that the project is located in the Shangejia Chemical Industrial Park in Tumerteyou Qi, with a total investment of about 7.2 billion yuan. The first phase of the project will invest 2 billion yuan to build an annual output of 200,000 tons of PVC equipment and an annual output of 150,000 tons of ion-exchange membrane caustic soda equipment and supporting facilities.
