沉淀法白炭黑是外观呈白色、多孔性无定形水合二氧化硅粉末,具有化学惰性,且耐高温、不燃、无毒、无味、无嗅。因其电绝缘性高、内表面积大,被广泛应用于橡胶、食品、医药、涂料等国民经济多个领域。梳理了国内沉淀法白炭黑主要厂家的生产能力、企业分布等基本情况,介绍了沉淀法白炭黑进出口情况、消费状况和行业技术进展等现状,并对沉淀法白炭黑应用前景进行展望,以期为沉淀法白炭黑生产企业和从事沉淀法白炭黑技术研究人员提供参考。

Precipitation silica is a white,porous,amorphous hydrated silica powder that is chemically inert and resistant to high temperatures,nonflammable,non-toxic,tasteless and odorless.Because of its high electrical insulation and large internal surface area,it is widely used in rubber,food,medicine,coating and other fields of national economy.The basic situation of the production capacity and enterprise distribution of the main manufacturers of precipitated silica in China were reviewed.The current situation of import and export,consumption status and technological progress of the precipitated silica industry were introduced,and the application prospects of precipitated silica was presented.A reference to precipitation silica manufacturers and researchers engaged in precipitation silica technology was provided.
