Application of precipitated silica
Application of precipitated silica
White carbon black is widely used in life industry, such as agricultural chemical products, daily chemical products, cementitious agents, anti caking agents, paper filler; in addition, it can also be used in many industries, such as fire fighting agents, feed, cosmetics, matting agents, pigments, paints, etc. the following brief introduction is about its application in pigments and ceramics:
Conventional ceramics generally contain 60-70% silica. However, the main component of most ceramic raw materials is silica, so this component generally does not need to be introduced in the formula in the form of pure silica raw materials.
Although organic pigments (Dyestuffs) have bright colors and strong coloring power, they are generally less resistant to light, heat, solvent and migration than inorganic pigments. The addition of fumed silica to surface modification of organic pigments has greatly improved the anti-aging properties of the dyes, and has also improved the brightness, hue and saturation of the products. The performance can be comparable to that of the imported high-grade products, which widen the grade and application scope of organic dyes.
Ceramics
Adding silica to 95 ceramics can not only play the role of nano particles, but also it is a two-phase particle. It not only improves the strength and toughness of ceramic materials, but also improves the hardness and elastic modulus of materials. Its effect is better than adding A1203. Using silica to composite ceramic substrate not only improves the compactness, toughness and smoothness of the substrate, but also reduces the sintering temperature greatly. In addition, the application effect of silica in ceramic filter screen, corundum ball and other ceramic products is also very significant. At the same time, it can also ensure the bright colors. Now the domestic white carbon black products have matured, welcome to consult.
Application of ultrafine silica
White carbon black physical and chemical properties.
The precipitated ultra-fine silica is made of high-quality precipitated silica (SiO2) and ultra-fine processing is carried out to make its particle size reach to microns, and its properties are similar to that of fumed silica. Due to the advanced equipment and technology, the product particle size distribution is narrow. Uniform particle size makes the product have rare high specific surface and excellent reinforcement and dispersion. It is used in high temperature rubber and silicone rubber to improve their tear strength. Therefore, it is a better choice to partially replace fumed silica and reduce the cost.
Precipitated ultra-fine silica is mainly used in silicone rubber, silicone rubber intermediates, mold glue, glass glue, as well as paint, ink, tire, sole, paint, cosmetics, pesticides, textiles and toothpastes.
Fumed Silica
Physical and chemical properties:
Fumed silica has the advantages of small particle size, large specific surface area, high structure and strong reinforcing property. Silicon alcohol group (Si oh) on the surface of silica ）It can form physical or chemical combination with silicon rubber molecules, form silicon rubber molecular adsorption layer on the surface of silicon dioxide, and form a three-dimensional network structure of silicon dioxide particles and rubber molecules, so as to achieve reinforcement. After being reinforced by fumed silica, the strength of silicone rubber can be increased up to 40 times. The application range: silicone rubber, tablets, cosmetics.
Fumed silica is suitable for use: silicone rubber: improve the aging resistance, resilience and compression deformation properties of silicone rubber.
Plastics industry: it can improve the toughness, strength and water resistance of plastics.
Coating industry: it can provide anti caking, anti sagging, thixotropic agent, thickening and extinction functions.
Medicine: it can play the role of thickening, suspension and carrier, and can also be used as powder and anti caking agent of pesticide.
