Market Research of silica
A brief introduction to silica
Silica is a general term for amorphous silicic acid and silicate. It is usually called fumed silica and precipitated silica in foreign countries, and fumed silica and precipitated silica in China. White carbon black is white powder granular, massive, nonflammable, nontoxic and tasteless, with good physiological inertia, insoluble in water, solvent and acid, but soluble in strong base and hydrofluoric acid, with good chemical stability. The structure and application performance of white carbon black are similar to that of carbon black. The appearance of carbon black is black, while the appearance of white carbon black is white, which is commonly called white carbon black.
The main component of silica is silica, which is commonly known as silica because of its reinforcing effect on rubber. The industrial production of silica can be divided into two categories according to its production technology, one is precipitated silica, the other is fumed silica. The two kinds of products have mature technology. By adjusting the process parameters, we have been able to produce dozens of specifications to meet the personalized needs of various fields, industries and products. Fumed silica, with its excellent stability, reinforcement, thickening and thixotropy, is unique in many disciplines and fields and plays an irreplaceable role.
II. Industry management, policies, regulations and industry standards
1. Industry competent departments and industry associations
The national development and Reform Commission and the Ministry of industry and information technology of the people's Republic of China undertake the macro management functions of the industry, mainly responsible for formulating industrial policies and guiding technological transformation.
China Association of inorganic salt industry is a cross regional, cross sector, cross ownership national industry organization, which is composed of inorganic salt production enterprises as the main body and other related entities. The association is a social intermediary organization and self regulatory industry management organization, which plays a role of bridge and link between government departments and member units.
2. Industrial policies and regulations support the development of silica industry
The "11th Five Year Plan" for the scientific and technological development of the chemical industry has listed it as a priority area, and the "11th Five Year Plan" for the scientific development of China's rubber industry clearly proposes to actively support the production of silica for radial tires, so as to facilitate safety, energy saving and reduce rolling resistance; the "Guiding Catalogue of industrial structure adjustment (2005 version)" has also listed it as a national encouragement Develop the industry. The support of relevant national industrial policies provides a broad development space for the industry.
3. Industry standard
In terms of standards, there are three levels of national standards, industry standards and enterprise standards in China, and two levels of international standards are ISO standards and corporate standards of multinational companies. For precipitated silica, there are a series of standards in China, including 14 industry method standards and 3 National method standards, among which Hg / T 3061-2009 technical conditions for Precipitated hydrated silica of rubber compounding agent is the product standard and the other standards are the method standards. The national standard of fumed silica in China is fumed silica (GB / T 20020-2005).
