1、 Production method of precipitated white carbon black
Precipitation method white carbon black is mainly obtained by reacting sodium silicate (water glass) with acids (such as sulfuric acid, hydrochloric acid) to form precipitates, which are then filtered, washed, dried, and calcined. By controlling reaction conditions such as material ratio, reaction temperature, and time, the specific surface area, particle size, and porosity of the product can be adjusted.


2、 Advantages of precipitation method for white carbon black
Low cost: The raw materials for precipitated white carbon black are mainly sodium silicate and inorganic acids, which are widely available and inexpensive.
Simple production process: Compared to gas-phase white carbon black, the production process of precipitation white carbon black is easier to control and has lower equipment requirements.
Large specific surface area: The specific surface area of precipitated white carbon black is usually between 145-300m ²/g, which can meet various industrial application needs.
Widely used: Precipitation white carbon black is widely used in industries such as rubber, plastics, coatings, toothpaste, and feed.


3、 Application of precipitation method for white carbon black
Rubber industry: precipitated silica is an important reinforcing agent for natural rubber and synthetic rubber, which can improve the wear resistance, aging resistance and mechanical strength of rubber.
Coatings industry: In coatings, precipitated white carbon black can be used as a thickener, anti settling agent, matting agent, and thixotropic agent to improve the rheological properties and adhesion of coatings.
Toothpaste industry: Precipitation white carbon black is a commonly used friction agent in toothpaste, characterized by strong adsorption capacity, uniform particle size, and high transparency.
Plastic industry: Precipitation method white carbon black can be used in plastic products to improve the hardness, mechanical properties, and transparency of materials.
Other fields: Precipitation white carbon black is also widely used in papermaking, pesticides, food additives, pharmaceuticals and other fields.


4、 Market position of precipitated white carbon black
Precipitation method white carbon black occupies a dominant position in the domestic silicon dioxide market, with a market share of over 90%. Its application fields are wide, especially in industries such as tires, shoes, and coatings, where the demand for precipitated white carbon black continues to grow.
Precipitation method white carbon black has broad application prospects in the industrial field due to its excellent performance and low cost, and is expected to be further expanded in more emerging fields in the future.
