General knowledge of coating: special application of titanium dioxide in Masterbatch

It is suggested that the color masterbatch is a kind of plastic colorant which is made of high proportion of pigment or additive and thermoplastic resin The selected resin has good wetting and dispersing effect on the colorant and good compatibility with the colored material It has the advantages of excellent coloring effect, convenient for automatic measurement and transportation, energy saving, no dust, no pollution and so on It is widely used in the coloring of plastics, coatings and other materials The development of Color Masterbatch The average annual demand growth rate of other countries in Asia is about 7% - 9%, but that of China is about 20% Projected Application scope and advantages of roller ceramic coating Recommended introduction: the surface of ceramic rubber plate used for roller ceramic coating is cast into durable rubber plate by hundreds of independent small ceramic pieces Each ceramic piece has raised characteristics Under general conveyor belt pressure, thousands of unique cast bumps can produce positive traction, prevent slipping and extend the service life of conveyor belt roller At the same time, the bottom layer adopts high-quality rubber, which has strong elasticity and can play a good impact resistance role The scope of application of roller ceramic coating is one three six 83857180 (the same as V) 1 Roller coating in extremely harsh working environment 2 The belt joint is not suitable for fixing with iron buckle; 3 It is suitable for leather Paint Home News: the color masterbatch is a kind of plastic colorant made of high proportion of pigments or additives and thermoplastic resin, which is well dispersed The selected resin has good wetting and dispersing effect on the colorant, and has good compatibility with the colored material It has the advantages of excellent coloring effect, convenient for automatic measurement and transportation, energy saving, no dust, no pollution and so on It is widely used in the coloring of plastics, coatings and other materials The development of Color Masterbatch the annual growth rate of demand for color masterbatch in other countries in Asia is about 7% - 9%, but the annual growth rate of demand for color masterbatch in China is about 20% It is expected that China will become the market with the fastest growth of Color Masterbatch demand Especially for color and adding masterbatch, China depends on import China has become the largest producer and consumer of Color Masterbatch Market in Asia At present, there are more than 400 color masterbatch production enterprises in China, which are mainly distributed in Guangdong, Zhejiang, Jiangsu, Shandong, Beijing, Shanghai, Hunan, Hebei and Tianjin They belong to various industrial systems, including more than 50 enterprises with an annual production capacity of more than 1000 tons, all over the country However, the total demand of color masterbatch in China is less than 120000 T / A, and the production capacity is in serious excess, which leads to the lack of start-up in domestic color masterbatch industry and fierce market competition Among these many color masterbatch manufacturers, the quality is not much, and small and medium-sized enterprises and individual enterprises account for a large proportion There is a serious overcapacity of production capacity, except for the factors such as the rapid growth of new production facilities and insufficient product orders; the important factors are the single structure of domestic color masterbatch products, the incomplete varieties, the large proportion of general-purpose products, while the proportion of high concentration and ultra-high concentration, multi-functional Color Masterbatch and fine denier fiber color masterbatch is small In contrast, in countries with high technology level of masterbatch, raw materials such as pigments and dispersants are complete, and a series and specialized product structure has been formed Overseas Color Masterbatch markets are mainly concentrated in Western Europe, North America and Japan Most of the enterprises producing color masterbatch are multinational companies or top 500 companies in the world, such as Hanna, poiyone, BASF, Hoechst, Ciba geigy, giarant and other companies in the United States, with an annual output of more than 1 million tons, of which Western Europe accounts for more than 50%, and Hanna's annual sales volume reaches 140000 tons The special application of titanium dioxide in color masterbatch the development speed of color masterbatch is very fast In addition, the production process of color masterbatch is simple, and the investment is few At present, there are hundreds of Color Masterbatch factories in China The production scale and technical level are uneven The small ones produce dozens of tons per year, and the large ones are tens of thousands of tons The product competition is increasingly fierce, the profits of production enterprises are declining, and the quality of most color masterbatch products is low According to incomplete statistics, the titanium dioxide used for the production of masterbatch is 20000-30000 tons per year, and the used rutile is divided into three grades: high-grade imported rutile, medium grade domestic rutile and low-grade domestic anatase titanium dioxide Due to the fierce competition, the use of anatase type titanium dioxide masterbatch still has an increasing trend There are several kinds of color masterbatch production processes, such as: pigment, resin, dispersant, volume pigment, other additives, high-speed mixer twin-screw machine extruding excellent Masterbatch color masterbatch is used as industrial raw materials, the performance is usually shown in the subsequent product application, therefore, the performance of titanium white in color masterbatch is mainly reflected in the application process of color masterbatch It is mainly reflected in the following aspects: 1) the coloring ability of titanium dioxide: determining the amount of titanium dioxide used for the same color of plastic products; 2) the whiteness of titanium dioxide: determining the appearance of light color (white) plastic products with the same titanium dioxide content; 3) the dispersibility of titanium dioxide: affecting the cost of production of color particles and the appearance, luster and other indicators of plastic products; 4) Processing performance of titanium white: it affects the production cost of masterbatch There is no standard for Color Masterbatch, and the standard for paint pigment is used Pigment is the raw material of color masterbatch The quality of pigment directly affects the quality of masterbatch, and the quality of masterbatch directly affects the quality of plastic products In other words, the requirements of plastic products on masterbatch, that is, the requirements of masterbatch on pigment This includes safety, heat stability, light and weather resistance, acid and alkali resistance, migration resistance, chemical resistance, etc However, there is no national standard for pigment used for masterbatch, and the standard for pigment used for coating has always been followed Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
