Carbon black as a rubber industry reinforcement materials have been nearly a hundred years of history. During the First World War, due to the shortage of energy, Germany began to use the precipitation of silica white production, that is, silica (this article only describes the rubber industry-related precipitation of silica) alternative carbon black. In recent years, due to the rapid development of automobile and its transportation industry, silica white production with raw material prices and energy-saving emission reduction requirements, the leader in reinforcing materials. Some silica factory began to produce silica white.
More than 80% of precipitation silica white produced in east China and South Africa, and concentrated in silica factory of Fujian, Shandong, Hunan, Jiangsu.
At present, China's precipitation of silica white product varieties and mainly to the middle and low, mainly for the footwear industry and ordinary tire production instead of carbon black reinforcement materials, a small amount for animal husbandry for feed additives; and some high-end products such as green and energy-saving tires, toothpaste, food, paint, cosmetics, paper and ink and other varieties or blank mainly rely on imports.
