二氧化硅消光剂，主要是以硅酸钠溶液加酸中和反应出来的硅酸盐液体，再经过过滤、洗涤、干燥后，通过先进的粉碎设备进行超细粉碎精制而成。是一种无毒无味、不可燃的白色蓬松粉末，仅溶于苛性钠和氢氟酸。受到高温不分解、不变色，但有一定的吸水性。
Silica extinction agent is mainly made of silicate liquid which is neutralized by sodium silicate solution with acid, filtered, washed and dried, and then refined by ultra-fine comminution with advanced comminution equipment. It is a non-toxic, tasteless, non-flammable white fluffy powder, only soluble in caustic sodium and hydrofluoric acid. It does not decompose or change color under high temperature, but it has certain water absorption.
