Introduction to precipitation method for silica dioxide
Precipitation method silica is a key inorganic chemical product widely used in many fields. Its preparation involves reacting soluble silicates such as sodium silicate with acid to form silicate precipitates, which are then subjected to aging, filtration, washing, drying, and other processes to obtain the final product.
In terms of physical properties, it is a white amorphous powder with a large specific surface area and strong adsorption ability. It can adsorb components in gases and liquids and has applications in adsorbents. The particle size distribution is controllable, and small particle sizes can enhance the reinforcement effect in rubber, improve the mechanical properties of rubber products, and are important additives in the rubber industry such as tire manufacturing; In coatings, it can improve rheology, anti settling, and weather resistance, making the coating evenly applied and long-lasting in appearance. In terms of chemical properties, it has high chemical stability and is resistant to acid and alkali erosion. It performs well in the field of chemical catalyst supports, providing a stable adhesion foundation for catalysts. Its porous structure facilitates contact between reactants and catalysts, improving catalytic efficiency. Good thermal stability, stable properties at high temperatures, suitable for high-temperature processing techniques or preparation of heat-resistant materials.
In the food industry, precipitated silica is commonly used as an anti caking agent to prevent food clumping and ensure the looseness and flowability of products, such as salt and milk powder; In the pharmaceutical field, it can be used as a drug excipient to improve the fluidity and compressibility of drugs, facilitate formulation molding, and also adsorb impurities in drugs, thereby improving drug purity and stability; In the paper industry, it can improve the strength, whiteness, and opacity of paper, optimize the printing and writing performance of paper; In the cosmetics industry, thickeners, stabilizers, and adsorbents are common, which can improve the texture and feel of cosmetics, absorb the oil and sweat secreted by the skin, and keep the skin dry. In summary, precipitated silica, with its unique properties, plays an extremely important role in many industries such as rubber, coatings, catalyst carriers, food, pharmaceuticals, papermaking, cosmetics, etc. It is an indispensable functional material in modern industry.
