The production of high-dispersion precipitation white carbon black requires multiple processes such as precipitation, filtration, and drying. It is produced by a chemical reaction between sodium silicate and an acid (usually sulfuric acid) to produce precipitation. There are higher requirements for the control of the reaction during the production of precipitation white silica.Many factors such as the quality of the raw materials, the concentration of each component, the temperature, the reaction time, the pH value and the stirring speed will affect the specific surface area and structure of the production of silica , Dispersion, and concentration of silanol groups, etc., each variable requires precise control and adjustment. Especially for high-grade white carbon black products used in tires, toothpaste, coatings, etc., it requires long-term theoretical and practical experience accumulation to achieve stable production, and it has higher requirements for enterprise R & D capabilities and talent reserves.

As a raw material for passenger safety tires, technical barriers and long customer certification cycles make the industry a high barrier to entry.Usually, domestic customer certification takes 1.5-2 years, and international customer certification takes 2-4 years. It is difficult for companies with supplier qualification to enter this industry. Highly dispersed white carbon black products are based on customer certification. Generally, self-promotion by manufacturing companies does not have commercial value. At the same time, once the customer certification is entered, the customer's stickiness to the enterprise will be very strong. The cost of replacing suppliers will also be huge. .
