气相白炭黑是硅橡胶(高粘度橡胶,HCR)制品的主要成分。由于它具有提高物理性能的独特能力,到目前为止是这种聚合物最为活跃的补强剂。从化学性质来看,气相白炭黑是一种无定形材料,由高纯度的二氧化硅(Si O2)组成,呈四面体结合成不大完美的三维结构,这样的结构中仅存在短程有序
Fumed silica is a major component of silicone rubber (high viscosity rubber, HCR) products. It is by far the most active reinforcing agent for this polymer due to its unique ability to improve physical properties. Chemically, fumed silica is an amorphous material consisting of high-purity silica (Si O2), tetrahedron combined into a less than perfect three-dimensional structure. In this structure, there are only short-range sequence
