2022-05-24 The main use of titanium dioxide Titanium dioxide is a white pigment whose main component is titanium dioxide. Therefore, the use of titanium dioxide is mainly discussed through the use of titanium dioxide. Titanium dioxide is a substance with excellent thermal stability and is an acidic amphoteric oxide. But it has photochemical activity. It is not very hygroscopic and has three crystal forms in nature: rutile, anatase and titanium. What are the uses of titanium dioxide, and what is the main purpose of titanium dioxide? 1. Coating: The coating is a viscous suspension composed of a binder, a pigment, a solvent and an auxiliary agent. Titanium dioxide is used as a pigment in coatings. The pigment has the function of covering and decorating to achieve the decorative appearance. At the same time, the pigment can enhance the mechanical strength and adhesion of the film and prolong the service life of the film. 2, plastic: titanium dioxide in the application of plastic products, in addition to its high hiding power, high achromatic power and its pigment properties, it can also improve the heat resistance, light resistance, weather resistance of plastic products, so that plastic products are free Infected by UV light to improve the mechanical and electrical properties of plastic products. 3. Ink: The white pigments used in the ink manufacturing industry are mainly titanium white powder and zinc white. Among them, titanium dioxide not only has good physical and chemical stability, but also has good resistance to various kinds of materials, and has lower prices than other ink materials. 4, paper: paper using titanium dioxide, whiteness, high strength, shiny, thin and smooth, does not penetrate during printing, under the same conditions, opacity is 10 times higher than calcium carbonate, talcum powder, weight can also be reduced 15%~30%. Therefore, decorative paper, Bible paper and banknotes must use titanium dioxide. 5. Rub

2022-05-18 Talking about the process of preparing calcium carbide raw material by replacing calcium carbide slag with limestone introduction Calcium carbide slag is a by-product of calcium carbide hydrolysis reaction in the production process of calcium chloride (PVC). With the development of the economy, China's PVC industry maintains a rapid growth momentum, the capacity of production equipment continues to expand, the scale of equipment is expanding, the structure is more reasonable, and the level of process technology is continuously improved. At present, more than 70% of the raw materials for producing PVC resin in China come from Calcium Carbide 50-80mm. Due to the development of PVC production by calcium carbide method, the discharge of Carbide Calcium slag is gradually increasing, and the pressure on the environment is increasing. Using the new dry process cement production technology, the use of calcium carbide slag for the production of cement clinker is an effective way to deal with calcium carbide slag in large quantities, but the characteristics of calcium carbide slag have a great impact on the cement production process, especially for the preparation and ripening of cement raw materials. The effect of material firing is very large. How to properly and effectively configure the cement production system for these characteristics is the key to this technology. The basic characteristics of calcium carbide slag mainly include the important physical and chemical properties of calcium carbide slag dewatering performance, carbide slag particle size, bulk density, thermal properties, sintering properties, etc. The specific characteristics of the slag have been described in detail in the literature [1] . These characteristics have a great impact on the transportation, dehydration, drying, storage, measurement and other aspects, each process link will have a greater impact on the quality of raw materials. This paper will focus on the preparation of raw materials for the production of cement clinker using calcium carbide slag. 1 c

2022-05-12 Industrial Grade White Caustic Soda Flakes 99% In the second half of March, the market for inorganic raw materials in the southwestern market was as follows: The supply of hydrochloric acid increased, and the price dropped steadily. Although the downstream demand is relatively strong, as the output further increases, the market supply is relatively abundant. The manufacturer`s offer declined due to increased inventory pressure. The current Southwest market price is 600-620 yuan (t price, the same below). Sulfuric acid supply and demand are booming and prices have stabilized. The downstream users have normal production and the volume of incoming goods has steadily increased. The trading situation is relatively good. At the same time, suppliers have normal production and supply and demand are basically balanced. Although the production cost of sulfuric acid was relatively high due to the impact of price increase of raw materials, the price remained stable after the previous period of increase. The current market price in the Southwest is 620-640 yuan. Caustic soda Due to the increase in production volume of manufacturers, the tightness of the former source of futures has eased. At the same time, the downstream demand remains strong, the trading atmosphere is active, and the supply and demand relationship is gradually calm. As the current price is already high, the pressure on downstream users is very high, so it faces greater upward resistance. The current market price in the Southwest is 2,800 to 3,000 yuan. The soda ash market is operating steadily and prices remain steady. Although the supply of raw materials is tight, and the price rise has brought certain constraints to the production of soda ash, resulting in a lack of early-stage stock supply, but after the active purchase of downstream users, the inventory has been better enriched, the recent purchase intensity is correspondingly weakened, the

2022-04-13 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. köksan pet resin According to different requirements, special grades of resin can have different 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 dak pet resin 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, PETgatronova pet resin 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

2022-04-12 Serious shortage of EVA resin for agricultural film "If it wasn't earlier that more than 2,000 tons of Ethylene Vinyl Acetate Resin PelletsEVA (ethylene-vinyl acetate copolymer) resin was purchased at a time for more than 14,000 yuan (t price, the same below), it would be miserable now, not only that the price rose to nearly 17,000 yuan, but also The supply is in short supply, and sometimes it is not always possible to buy goods with money." Liu Hongjian, the Minister of Mining and Supply of Tianjin No. 2 Plastics Factory, said in an interview with reporters recently. Ethylene-Vinyl Acetate. Liu Hongjian's words reflect the real situation in which domestic production of EVA resin Ethylene Vinyl Acetate Resin Pellets for agricultural membranes has been insufficient for many years. This situation has not been fundamentally improved even after the highly-requested 200,000-tonne/year EVA plant of Yangzi Petrochemical-BASF Co., Ltd. was put into operation. The production of agricultural film has a higher requirement for the VA (vinyl acetate) content of EVA resin Ethylene Vinyl Acetate For Adhesive, and cannot be higher than 40%. Generally, products with a VA content of about 14% are used. It is understood that at present, China's industrial EVA production enterprises, only Yang-Pak Corporation and Beijing Dongfang Petrochemical Company organic chemical plant and other individual companies, the annual production capacity of 240,000 tons. However, in the EVA produced by domestic companies, less than 10,000 tons of plastic film can be used for the production of agricultural film last year. In 2006, the actual production of Yangzhou-Baba EVA membrane material (V4110F) was only 8,000 tons, and Beijing Oriental did not produce EVA resin for agricultural membranes this year. Due to the huge supply and demand gap, the ex-factory prices of V4110J, V5110J and Beijing

2022-03-18 PVC K67:what is the cause of the fisheye of pvc resin ? Fisheye is actually a small amount of ultra-high molecular weight PVC with a molecular structure formed by improper conditions in the polymerization process. Due to its low ability to absorb plasticizers, it can only swell plasticizer under normal processing conditions. Plasticization, but the fisheye problems encountered by processors are not all such body-shaped structures, most of which are plasticized pseudo fish eyes. These pseudo fish eyes are linear structural resins with high molecular weight. Its physical configuration is caused by the tightness of the packaging organization. There are many ways to form fisheyes. For example, the molecular weight distribution of PVC is too wide, which results in low molecular weight plasticization under the same processing conditions, while molecules with high molecular weight are slow to plasticize. If the processing conditions are certain, the plasticized slow polymer will appear in the case of fake fish eyes in the product. Improper distribution of the initiator will cause the concentration of the initiator in the polymerization system to be too high, causing the local reaction of the polymerization system to be too fast, and the heat is difficult to be transmitted in time, resulting in local overheating to form fish eyes. Inappropriate choice of initiator, easy to lead to PVC cross-linking, the formation of permanent "fish eye", the initiator is not properly matched, due to the difference in reaction temperature before and after, easy to form a temporary fish eye. If the stirring speed is too slow, the particles are unevenly dispersed and easily opened. However, the stirring speed is too fast, and the oil droplets formed by the stirring shearing slightly rupture the film to cause the particles to be granulated. In both cases, large particles are prone to occur, forming a temporary fisheye.E

2022-03-17 High-impact Polyvinyl Chloride Resin Obtains National Invention Patent Chemplast Pvc Resin independently researched and developed by Henan Lihao Chem Plant Co., Ltd. has obtained national invention patents. High-impact PVC composite resin is a new type of composite material, which combines impact resistance, wear resistance, aging resistance, corrosion resistance, flame retardance and other excellent properties. It is mainly developed for the poor impact resistance of domestic general PVC resin. For a long time, domestic PVC products have been mainly used for blending methods for toughening, and there are limitations such as less variety and poor quality. At the same time, the impact resistance and rigidity of PVC sg5 can not be taken into account at the same time, and there is a strong dependence on the blending processing conditions. Some domestic large-scale PVC production enterprises have begun to increase R&D investment in the field of special and special PVC resins, and initiated high-impact high-impact PVC composite resin products, but they have not been successful. At present, Shenghua Chemical's annual production capacity of 10,000 tons of high-impact Polyvinyl Chloride Resin industrial production line has been put into production, Ethylene-Vinyl Acetate ,and the polymerization reactor production equipment has reached 30 cubic meters.

2022-03-08 Pvc is what material pvc material price is how much Pvc material can be seen everywhere in our lives, pipes, films, plastics, wires, mineral water bottles, wall panels, flooring, consumer goods, etc. Whether it is home life or office supplies, products made of PVC materials are almost everywhere. So, what is pvc? What is the price of pvc material ? Let's take a look with Xiaobian. What is the pvc material? Pvc Plastic is actually a vinyl polymer material Rubber And Plastic, and its material is a non-crystalline material. In practice, PVC materials often include stabilizers, lubricants, auxiliary processing agents, colorants, impact modifiers, and other additives. With non-flammability, high strength, weather resistance and excellent geometric stability. PVC is very resistant to oxidants, reducing agents and strong acids. However, it can be corroded by concentrated oxidizing acids such as concentrated sulfuric acid, concentrated nitric acid, and is not suitable for applications in contact with aromatic hydrocarbons or chlorinated hydrocarbons. In addition, the term person vs computer, abbreviated as PVC, and PVC human form are often referred to as Pvc Resin. Pvc Plastic Material can be divided into soft PVC and hard PVC. Hard PVC accounts for about 2/3 of the market, and soft PVC accounts for 1/3. Soft PVC is generally used on the surface of floors, ceilings, and leather. However, since soft PVC contains softener (which is also the difference between soft PVC and hard PVC), it is easily Ethylene-Vinyl Acetate brittle and difficult to store, so its use range is limited. Hard PVC does not contain softeners, so it has good flexibility, easy molding, is not brittle, non-toxic and non-polluting, and has a long storage time. Therefore, it has great development and application value. The essence of PVC is a vacuu

2022-03-03 In October, the export of PVC pure powder decreased significantly compared with that of liquid alkali exports. According to the latest statistics from the Customs, the import volume of Pvc Powder (pure powder) reached 63,200 tons in October, a decrease of 13% from the previous month. Among them, the general trade volume of polyvinyl chloride (pure powder) in October was only 1,200 tons, which continued to decline. The top three importers of Pvc Resin Sg5 pure powder in October were Japan, the United States, and Taiwan, with imports of 22,000 tons, 17,000 tons, and 15,000 tons, followed by Indonesia, Thailand, and South Korea. In September, the export volume of polyvinyl chloride (pure powder) was 32,600 tons, a Rubber And Plastic decrease of 42.6% from the previous month. Due to the recent seasonal decline in demand in Central Asia, the price plummet of the Indian market due to climatic reasons and artificial speculation also dampened the enthusiasm of Chinese exporters, resulting in a decrease in the export volume of PVC pure powder. In October, the export volume of liquid caustic soda was 82,300 tons, which continued to increase significantly from the previous month; the export volume of solid caustic soda was 37,600 tons, a Sodium Hexametaphosphate decrease of 32.7% from the previous month. The signing of the long list of liquid caustic soda in October Titanium Dioxide prompted a significant increase in the number of exports, while the demand for solid caustic soda in Southeast Asia showed a weaker trend, which resulted in a downward trend in export prices of solid caustic soda, which affected the enthusiasm of Chinese exporters.

2022-03-02 Caustic soda market trend analysis This week, the domestic Caustic Soda Market process fell slightly. According to statistics from the Business Society, the average price of the domestic 32% ion-exchange membrane caustic soda factory at the beginning of the week was 793.33 yuan per ton, and the average price at the weekend was 788.33 yuan per ton, a decrease of 0.63. %. The year-on-year price fell by 0.68%. The market price of caustic soda this week showed a slight drop. Prices in most parts of the country were relatively stable, and only individual companies lowered their ex-factory prices. The reasons for the downward trend in domestic caustic soda prices this week are as follows: 1. The domestic crude salt market has a relatively high start-up and sufficient market supply. Second, the demand market trend is weak, downstream alumina and other major alkali-consuming industries are generally in demand, and are basically purchased on demand. The demand has not seen an increase trend. Third, some domestic enterprises are in maintenance Water Treatment state, and the supply of caustic soda on the market is decreasing. Therefore, the caustic soda market has a tendency to stabilize. The market demand for Caustic Soda Flakes 99% has shrunk. The pressure from caustic soda manufacturers is relatively high. Analyst Cao Huaxia, a caustic soda analyst at the company's chemical branch, expects that the caustic soda market will continue to be Sodium Hexametaphosphate dominated by weaker positions, Titanium Dioxide with less price fluctuations.

2022-03-01 Soda ash and caustic soda prices fall and electricity is hard to change The "two-alkali" (soda ash, Caustic Soda) industry that has performed well in the first half of this year seems to have entered a turning point. Even if the peak of electricity usage in summer comes, the limited voltage will be reproduced, and it is difficult for the market to replicate the economic conditions in the first half of the year. The reporter learned from a number of industry organizations yesterday that due to the recovery of Japan's chlor-alkali production capacity, the export prices of soda ash and Caustic Soda Flakes have recently fallen, and the outlook is not optimistic. According to Li Wei, a researcher of China National Chemicals Network, the nationwide soda ash market has recently experienced a weaker downward trend. In some regions, power cuts have not caused much impact on the operating rate, and manufacturers have started normal operations. [At present, there is no obvious power restriction policy in Shandong and the start of construction is relatively normal. However, the soda ash markets around the country have experienced a substantial decline recently. Under this pattern, it is difficult for the post-term electricity to have a substantial impact on the soda ash industry." Information analyst Wang Hui told this reporter. It is worth noting that in Water Treatment order to change the situation of falling prices, the recently held soda ash area meeting even proposed "limited production and price protection" measures. According to Li Wei, the meeting proposed to limit production by 15%, so that the price of light alkali is maintained at 2,200 yuan / ton, and the price of heavy alkali is maintained at 2,300 yuan / ton. However, according to her understanding, the price of light alkali in Shandong has actually dropped to 2100-2150 yuan / ton, and the price of heavy alkali is

2022-03-01 The domestic caustic soda market has steadily reduced the business confidence in the market outlook The domestic Caustic Soda Pearls market has steadily dropped. Affected by large alumina companies such as Shandong Weiqiao, the price of liquid caustic soda in Shandong chlor-alkali enterprises was slightly reduced, and the confidence of merchants in the market was bleak. The overall lack of enthusiasm for trading. It is understood that the 800,000-ton alumina project in the Guizhou Comorochuanchuan Autonomous County has actually started. The Department of Industry of the National Development and Reform Commission has agreed in principle to add the second phase of the 1 million-ton alumina project. The demand for liquid caustic soda will increase next, which is expected to boost the local area. Liquid caustic soda market. Short-term interest is limited, it is expected that the Caustic Soda Flakes 99% market will be closed in a narrow range. The caustic soda Water Treatment market in Yunnan is mainly stable, with an ex-factory price of 32% ion-exchange membrane base at 2200-2250 yuan/ton (100%), and 50% ion-exchange membrane base at 2250-2300 yuan/ton (100%). Market turnover general. The local chlor-alkali enterprises are producing at full capacity, and the downstream alumina companies are buying normally. It is expected that the market will not have large fluctuations in the near future. The performance of the caustic soda market in Henan is light and steady. The mainstream ex-factory price for 32% ion-exchange membrane base in this area is reported to be 1750-1850 yuan/ton, and the price of some companies is slightly higher. The local caustic soda enterprises started with stable load, stable shipments, downstream consumption of alumina and other alkali-consuming industries, and there was no volatility in the market. It is expected that the caustic soda market will continue its steady consolidation. The caustic soda market

2022-02-24 Eastman Launches Reheatable PET Resin Eastman Chemical Corporation, the world's largest producer of PET resin for packaging, launched a product of the specification Aqualor PET, which is the first and only PET material that can withstand hydrostatic loading and can be reheated. Aqualor PET was launched at the PETnology trade fair in Munich, Germany. The main focus is on the European market. It shows great energy efficiency in preform and preform production, enhanced product protection and an unprecedented appearance. Aqualor Pet Resin greatly improves pre-finished and preform processing, while also producing exceptional preform clarity and gloss and precision in printed content. Roland Leimbacher, Marketing Manager for Eastman Europe Functional Polymers, said: [Preform manufacturers, pre-manufacturers and trademark owners can all benefit from Eastman's Aqualor PET resin. Our new resins are actually improving end-use applications. At the same time as appearance and performance, molding is faster and Pvc Resin cheaper. This is another example of Eastman's creativity in operation." For pre-finished and preform manufacturers, the economic benefits of Aqualor processing can be increased with faster flow rates and lower energy consumption. For blow-molded bottles, the energy required for reheating Pet Resin Iv0.80 can be reduced to 30%; also, its value is 0.72. IV Low viscosity not only guarantees the fastest injection speed and Rubber And Plastic long-term life of preform molding, but also ensures preforms The best accuracy of printed content (embossed or embossed). Improve brand appeal The most noteworthy of Aqualor is the PET bottle designed to withstand hydrostatic loads with the highest brilliance and clarity. While other reheatable resins often produce unattractive haze, Aqualor PET can produce very good bottlenecks and sidewall sharpness, which is the key to improving shelf appeal and brand image. Aqualor's easy-

2022-02-24 Single-layer PET beer bottle resin is available in the United States Recently, the United States Invista successfully developed a PolyShield resin with excellent gas barrier properties, which has made breakthroughs in the production technology of Pet Resin beer bottles. The technology that would previously require multi-layered composites to produce beer bottles will be replaced. Monolayer production can be. Industry insiders analyzed that single-layer Pet Bottle Resin produced using this new type of polyester resin can meet the EU food safety standards for beer packaging. This material is a new kind of PET blend resin with strong oxygen-absorbing and gas-barrier properties. It significantly improves the barrier properties of single-layer PET beer bottles to oxygen and carbon dioxide gas, and meets all beer shelf-life standards. PolyShield has recently been approved by the Rubber And Plastic European Union for beer packaging food safety laws and can be directly used for beer packaging. An ordinary injection molding machine can produce PolyShield single-layer beer bottle preforms, downstream manufacturers do not need significant additional investment and will not increase Boric Acid Flakes the complexity of the production process. Multi-layer conversion to a single layer, which greatly reduces the cost of the product. At present, this Melamine Powder technology has already begun trials in several beer production plants around the world and is expected to produce good economic benefits.
