2022-11-14 Float level gauge points of use EVA RESINFloat level gauge is widely used in liquid level, chemical industry, metallurgy, electric power, paper making, food and industrial sewage treatment and other departments. By the magnetic reed switch, precision resistors and amplification transform circuit. When the magnetic level gauge magnetic float to a certain position of the reed switch, the reed switch is closed, so that the amplifier output conversion circuit with the measured level corresponding to the current value, as the level changes, Amplifier conversion circuit level will be converted into a linear 4 ~ 20mADC signal output, in order to achieve the level of signal transmission or control. Float level gauge use points: 1, EVA18J3 the level gauge calibration is normal, cast and found the float in a certain position for a period of time "sucking" phenomenon. This is mainly the level gauge through the steel platform device, the gap between the plate and produced. Therefore, special attention should be paid to the clearance between the liquid level gauge pipe wall and the cutting edge of the platform through the steel platform device. Based on field experience, this distance is about 100 mm to ensure that no impact on the magnetic float. 2, EVA on-site adjustment will find the float moving up and down not sensitive enough. This is mostly due to improper liquid level gauge caused by the device, this time to pay attention to the center of the flange can be up and down in a line, with the degree of vertical plane. Generally speaking, the best angle with the degree of not less than 87 degrees, if the bias is greater, may affect the smooth movement of the float. 3, when the level gauge cast on the spot, pay special attention to open the upper gate valve, then open the lower gate valve. This is due to the level gauge connected to the bottom of the tube is equipped with a maintenance of the float spring, otherwise, the role of large differential pressure float may cause the float

2022-11-07 What is the weatherability of iron oxide pigments? Carbon + Iron Oxide is generally considered to be a multi-colored pigment that has many properties that are not found in other pigments, such as tinting strength, Boric Acid Flakes oil absorption, and the like. The weatherability of iron oxide pigments is described below. The light fastness and weather resistance of Coating Of Iron Oxide Crossword Clue Iron Oxide Density are important indicators for measuring the application properties of pigments. Weatherability is a term used to describe various changes in the appearance and functional value of colored coatings. It covers a full range of external use capabilities such as color and gloss retention, chalking, adhesion and film integrity. Its initial impact is caused by exposure of organic binders to exposure to sunlight, Sodium Hexametaphosphate moisture, temperature changes and environmental pollution. The pulverization is due to the increasing separation of the organic binder from the surface of the paint film, leaving the pigment exposed to the air and some extender particles, thus forming a powdery powdered appearance. This change will result in a change in color and a decrease in gloss. Iron oxide has the function of shielding Titanium Dioxide ultraviolet radiation and can extend the application life of the coating. To achieve excellent film weatherability, you must choose the right ingredients. According to different coating system environments, iron oxide pigments with different crystal forms and particle sizes can be selected to improve the weather resistance of the coating. In general, inorganic pigments become darker and darker by the action of sunlight and the atmosphere, while organic pigments mostly fade. In general, the light resistance and weather resistance of inorganic pigments are much stronger than those of ordinary organic pigments. If the

2022-06-28 Titanium Dioxide Rutile/Anatase in Coatings Rubber Plastic Titanium dioxide is a white pigment with excellent performance. It is widely used in coatings, rubber, plastics, household chemicals and other fields. Its market value is second only to the third largest inorganic chemical products of ammonia and phosphorus chemical industry. The growth rate of titanium dioxide consumption in China obviously exceeds the growth rate of GDP. If we can maintain a high-speed growth trend, it is expected to become the world's largest producer and consumer of titanium dioxide within the next five years. In the past two years, thanks to the improvement of supply structure in the downstream industries and the release of demand for architectural coatings, titanium dioxide is still in the post-cycle phase of rising demand, and its prices have ended the continuing downturn in previous years. According to this growth trend, the titanium dioxide boom cycle is expected to continue into the second half of next year. In the past ten years, the processes and technologies based on the sulfuric acid process have been improving day by day, and the single-line production capacity has been greatly increased. As a result, titanium dioxide production capacity has enjoyed rapid growth, and the compound annual growth rate has reached 15% in the past eight years. According to statistics, in 2016, the total production of titanium dioxide in 39 companies was 2,597,212 tons, an increase of 274,199 tons compared to 2015, 23,230,012 tons, an increase of 11.8%, and a record high. The apparent consumption of titanium dioxide increases at an average annual rate of about 14%. The apparent consumption of titanium dioxide in 2011 was 1.64 million tons. In 2012, due to the decline of titanium concentrate production, the growth rate of titanium dioxide production in China declined slightly. Views of consumption reached 1.8 million tons, an increase of 9.76% over the previous year. In

2022-06-10 Caustic soda: The off-season arrival of liquid caustic sore With the arrival of the off-season, after a long period of high levels in liquid Caustic Soda Per Kg Price, the downstream is exhausted, and some of the downstream alkali-alcoholic industries are declining. The recent domestic liquid caustic soda market has a bearish sentiment. In particular, the liquid Caustic Soda And Sodium Hydroxidemarket in northwestern Inner Mongolia and Ningxia, due to the lower enthusiasm for the high-value liquid alkali liquor to be received, together with the inventory of liquid caustic soda from individual manufacturers, the high-end transaction center of gravity has declined. The local mainstream shipment price of 32% ion alkali dropped from 2650-2750 yuan/ton to 2600-2650 yuan/ton. Affected by this, the wait-and-see atmosphere in the liquid caustic soda market in some eastern regions gradually began to take off. It is reported that chemical fiber and other downstream industries in some parts of eastern China are declining. Some manufacturers also have a moderately bearish attitude. From an economic point of view, PMI data in June was at 50.2%, which was a decrease of 0.2% from the previous month, indicating that the downward pressure on domestic economy still exists. The National Bureau of Statistics released CPI and PPI data yesterday, showing a year-on-year increase of 2.2% in CPI. However, the increase in PPI was -2.1%. Overall, the domestic economy is still not optimistic. Some market participants even have doubts about whether China will enter deflation. Under such circumstances, the market's appeal for stimulus policies has been skyrocketing. We believe that the central bank will continue to adopt certain stimulative measures to hedge against the economic weakness. However, in the short term, the economy will have a much better recovery. Big. From the perspective of the supply and demand side of the current

2022-06-09 Titanium Dioxide Industry "Rejuvenated" Export volume is gratifying In 2017, the tititanium dioxide in food industry [returned to life" and came out from the trough of 2014-2015 and returned to the high price point of 2011-2012. Since last year, under the guidance of the [Thirteenth Five-Year Plan" policy guidelines, the new production capacity of titanium dioxide in 2017 has been limited, and the traditional sulfuric acid production process has been limited by national policies. Enterprises actively promote the new chlorination process, but the chlorination process Difficulty in the process technology, the actual new capacity is limited, in 2017 only Shandong Jinhai titanium chlorination process put into operation, 2018 is expected to have about 400,000 tons of chlorination plant capacity production. Pvc Resin. In 2017, the tio2 industry was greatly affected by environmental protection factors. The environmental protection cost of enterprises further increased, and the environmental cost of titanium dioxide per unit rose by RMB 500-1,000/ton. Some enterprises that were not up to the standard were limited in their start-up operations, and enterprises with production capacity less than 50,000 tons were even more After being eliminated, the titanium dioxide industry has further accelerated its integration. In addition to the local government`s environmental inspections, the Central Environmental Supervision Group has also entered various provinces and cities. After the major safety inspection, the main raw material of titanium dioxide titanium mine operating rate is low, raw material supply was tight; the domestic largest titanium dioxide company Long Yaoli Union (002601, stock bar) received the local government's current limited production notice in mid-September.

2022-06-06 Brief description of the use of EVA resin ThePrice Of Eva Granules is an ethylene-vinyl acetate copolymer, and the content of vinyl acetate (Va) is generally 5% to 40%. Compared with polyethylene, Eva Granule is widely used in foaming shoes due to the introduction of vinyl acetate monomer in the molecular chain, which reduces high crystallinity, improves flexibility, impact resistance, filler compatibility and heat sealing performance. Materials, functional shed film, packaging film, hot melt adhesive, wire and cable and toys. In general, the performance of an Specification Ethylene-vinyl Acetate ( Eva ) depends primarily on the content of vinyl acetate on the molecular chain. In 2001, the market consumption of EVa resin in China was about 290 kt. With the development of China's footwear industry and the increase in the use of functional greenhouse film, the demand for EVA resin in China will increase year by year.Pvc Resin. (1) Foamed shoes Shoe material is the most important application field of EVA resin in China. In the EVA resin used for shoe materials, the vinyl acetate content is generally from 15% to 22%. Because EVA resin blended foamed products have softness, good elasticity and chemical resistance, they are widely used in the soles and interior materials of medium and high-grade sneakers, hiking shoes, slippers and sandals. In addition, this material is also used in the field of acoustic panels, gym mats and sealing materials. China's Guangdong Shunde, Zhongshan, Fujian's Jinjiang, Quanzhou and Zhejiang's Wenzhou are the main production bases of China's footwear industry, consuming a large amount of EVA resin products every year. In 1999, China's foamed shoe materials and shock absorption fields consumed about 150kt of EVa resin.Ethylene-Vinyl Acetate (2) film The main use of EVa films is in the production of functional shed films. The functional shed film has high weather resistance, anti-fog drop and heat preservation performance. Since

2022-05-30 Basic Knowledge of PET Resin Pet Bottle Resin Pete Resin 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 applications Melamine Powder. Sodium Hexametaphosphate PET is a long chain (long chain of molecules is shown by the number of basic units), a Titanium Dioxide 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 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 (polybutylen
