In the rubber industry, there is a seemingly insignificant but crucial material - precipitated white carbon black. It has become an indispensable reinforcing agent for rubber products due to its unique performance and wide range of applications.
Precipitation method white carbon black, also known as hydrated silica, is produced by chemical precipitation method. The production process generally involves using fuel or gas to react quartz sand with soda ash at high temperatures to produce industrial water glass. Then, the industrial water glass is mixed with water to form a dilute solution of a certain concentration. Under certain conditions, a certain acid is added to precipitate silica, and the product is produced through processes such as cleaning, filtering, drying, and crushing. This production method makes precipitated white carbon black have the characteristics of larger particle size, relatively smaller specific surface area but wider distribution.
In the rubber industry, the application of precipitated white carbon black is extremely widespread. It can significantly improve the tensile strength, tear strength, and wear resistance of rubber, making rubber products more durable when subjected to external forces. Meanwhile, precipitated white carbon black can also improve the processing performance of rubber, such as fluidity and uniformity during extrusion and molding processes, making rubber easier to handle during processing. Therefore, it is widely used in rubber products such as car tires, seals, and shock pads.
In addition to the rubber industry, precipitated white carbon black also plays an important role in other fields. In the coating industry, it can be used as an additive to prevent pigment precipitation, improve the suspension stability and weather resistance of coatings. In the paper industry, it can improve the whiteness and opacity of paper, making it more wear-resistant and oil resistant. In the pesticide and feed industries, it can be used as a carrier or diluent to improve the suspension rate and long-lasting efficacy of products.
With the continuous advancement of technology and the improvement of environmental awareness, the production process of precipitated white carbon black is also constantly improving. By optimizing the precipitation process, drying, and granulation process, the dispersibility and performance of the product can be further improved. At the same time, the development of nanoscale white carbon black with higher specific surface area and better performance, as well as multifunctional white carbon black with antibacterial, conductive and other properties, will meet the needs of more high-end application fields.
Precipitation method white carbon black has become a hidden champion in the rubber industry and many other fields due to its unique properties and wide applications. In the future, with the continuous advancement of technology and the expansion of the market, the application prospects of precipitated white carbon black will be even broader.
