Analysis of the current situation of chromophore
The Chinese chromophore industry started in the mid-1970s. After more than 30 years of rapid development, especially from the 1990s to the present, China's color mother-grain industry now has an annual production capacity of 300,000 tons, which can basically meet the needs of the plastics and chemical fiber industries.
In the next few years, China's chromatin industry is expected to enter a steady development, moving toward multifunctional, high pigment content and high technical content.
Distinctive regional features
At present, the color mother grain industry in China is showing a weak situation in the South and North, and weak in the East and West. Manufacturers with an annual production capacity of more than 1,000 tons are the pillars of the development of the industry. There are more than 250 domestic non-ferrous parent grain production enterprises, of which more than 50 large enterprises have more than 60 % of the total production capacity, mainly concentrated in Guangdong, Jiangsu, Zhejiang, and Shanghai. In particular, large enterprises with an annual output of more than 1,000 tons are mainly gathered in the South..
This distribution also shows the same trend as the Chinese economic development. Some good color granule enterprises can tailor the required color granule varieties according to customer requirements. Each enterprise has its own characteristics and expertise, which can basically meet the needs of domestic customers. Many color granule factories can also produce functional master and plastic modification materials.
Domestic chromopolymer production capacity according to geographical distribution, Guangdong production capacity is very large, accounting for 41.82 of the total production capacity; Jiangsu, Zhejiang, and Shanghai accounted for 33 %; Shandong 10.62 <UNK>. These regions account for more than 85 % of the production capacity of Chinese chromophores. It can be seen from this that the southeast coast is the main area where the color mother grain industry develops in China.
Varieties tend to be diverse
The variety of Chinese color mother grain is more complete, and the generic products can fully meet the needs of the domestic plastic processing industry. The distribution of domestic chromophore varieties is analyzed according to the color of the chromophore varieties. Black and white mother grains account for almost 80 % of the total chromophore production capacity, and color mother grains account for only 20 <UNK>. At present, a large part of them still rely on imports.
In chromatid grain production, fiber chromatid granule has higher requirements for technology and raw materials, and chromatid granule production technology is also due to the coloring of polypropylene fiber. The total annual output of domestic fiber color granule has reached 2.6 W tons, accounting for 10 % of the total production capacity of color granule. It can thus be seen that the technology invented by the chromatin to solve the polypropylene coloring problem has been widely used in the field of plastic coloring.
PET and PP fibers have developed rapidly in China, while PA fibers account for a relatively small market share. The ratio of PET, PP, and PA fiber color parent grains is currently 68.2, 30.2, and 1.6, respectively. With the establishment of the PA project of multinational companies in China, China's research and development and production of PA-colored parent grains must also catch up.
With the rapid development of engineering plastics in China in recent years, engineering plastics such as PA, PC, fluorine plastics and special engineering plastics have put forward higher requirements for chromophore particles. The Institute of Materials Science and Engineering of Beijing University of Chemical Industry has recently developed polyfluorinated acrylate(PFC) granule, which fills the gap in the country. In the process of research and development, it has solved problems such as raw material selection, formulation and production process adjustment. The polyfluorinated polyethylene acrylate granule of white, yellow, green, blue, red, orange, brown and black panchromatic lines was successfully prepared and applied to wire and cable. The electrical and mechanical properties met the requirements. The successful development of this project has laid a good theoretical and practical foundation for the development of high-grade chromatids used in engineering plastics in China.
Foreign businessmen grab beaches
It has become one of Asia's very multi-color mother grain producers and demand countries. It is also a very large demand market in the world in the future. According to relevant data, the average annual growth rate of demand for chromophore in other Asian countries is about 7 to 9, while the average annual growth rate of demand for chromophore in China is about 20, and China will become a market where chromophore demand grows very fast. This enticing cake has attracted the international color mother granule giant to flood the Chinese market.
In the 1990s, foreign color granule companies began to enter China. In September 2000, GeonandM.A. Hanna jointly founded POLYONE, a polymer service company known as the world's largest, and built colored parent grains and engineering plastics production bases in Shanghai, China, Suzhou and Shenzhen. In September 2005, POLYONE Shenzhen Base carried out a large-scale expansion and built seven production lines.
The Colleen color granule department is a very large supplier of color granule and functional granule in the world. It has been active in the Chinese market since 1995, has a full-service factory in Guangzhou and Beijing, and was in Shanghai in November 2004. The Xinzhuang Industrial Park established the third production base in China. Mainly for East China and international customers to provide color and functional granule services.
PCC, a subsidiary of the United States PMC, is building a chromatid granule plant in Nanjing. The first phase of the project is expected to have a production capacity of 50 tons/month liquid body color base material for PET blowing bottles. The pigments are mainly used by foreign companies such as BASF and Sauba. Products, the second phase of the project is expected to produce solid body color base material.
In addition to the original United States, Switzerland, and Japan, Singapore, South Korea, and other factories are also established in China. In particular, some special engineering plastic color mother varieties occupy an advantage and grab the high-end market of color mother grains, further intensifying competition.
Diversification of raw materials
To a large extent, the quality of chromophore grains depends on the supply of raw materials such as pigments and dispersants. After many years of development, Chinese plastics pigments have also made great progress. Domestic pigments such as Jiehong, Lily, Yabang, and some titanium dioxide and carbon black companies have high quality pigments and can meet the requirements of color parent grains. Foreign pigment manufacturers such as DuPont, Clane, Ciba, and BASF have established factories in China to provide high-end pigments for domestic chromophores production. Domestic pigments are similar to those of foreign medium paints, but there is still a certain gap in the purity of products, especially in the surface treatment of pigments, compared with high-end pigments.
The dispersant is an auxiliary agent that provides infiltration, dispersion, and stability for pigments in the chromophore. The dispersant in the Chinese chromophore market mainly uses polyvinyl wax, which is polymeric, pyrolysis, and by-product.
These three types of low relative molecular weight polyethylene each occupy a certain market. Polymeric wax or imported wax is used by multinational companies in China and domestic chromophores core enterprises, while low-end chromophores generally use lower-grade by-product wax, which mainly occupies a great advantage in price.
The quality of cracking wax is good, and it occupies a very important position in dispersants used in chromophore grains. The quality of domestic cracking wax has become increasingly close to foreign companies such as Honeywell and BASF after the efforts of domestic generations of generations of generations of generations of chemical workers. Synthetic level. It also highlights a group of good companies such as Qingdao Sainuo. The products have received multi-domain application certification in the market and have obtained a good reputation in the industry.
There is also a market for complex waxes popular in the domestic market, such as adding liquid paraffin wax to polyethylene wax or adding other cheap Auxiliaries. This kind of wax also has a certain market because it has a certain value for money advantage.
For polyolefin color parent grains, there is no dedicated brand of carrier resin production in China. The very multi-generation carrier resin used for polyolefin chromatin is amorphous polypropylene, and the secondary carrier resin is low-density polyethylene. In recent years, linear low-density polyethylene has also been developed as a carrier resin, but there is currently no large-scale market. In other varieties, the colored resin was used as the carrier resin of the same color mother granule.
At present, the industry is developing towards multifunction, high pigment content and high technology content. In order to comply with the trend of development, domestic enterprises concerned with pigments, dispersants, carrier resins and equipment should increase the technical content of their products. Provide high quality pigment, dispersant, special brand carrier resin as well as advanced production equipment, testing equipment and application software for color mothergrain manufacturers.
The chromatid granule manufacturers should strengthen the overall quality management and produce a variety of chromatid granule products with stable quality and complete functions, so as to contribute to the development of plastics and fiber industry in China.
