Application Scope of Silica

Sodium silicate and silica silica chemical processing products. Sodium silicate is the most versatile in silica chemical processing products, most consumable products, besides, in which silicon compounds are used in the manufacture of a variety of metal material is widely used for board, plywood, part also and foundry industrial glue, soap, detergent additives, paper properties improver, in the textile industry for cotton scouring and bleaching agent, fabric fire treatment agent, dye chromogenic agent. In addition, also used as a coagulant aid cement, wood preservative and antistaling agent of eggs. Sodium silicate after modification also can be used as wall. Aluminum silicate glass, pottery and porcelain in the raw material, also can make the paint pigments. Lithium silicate anticorrosive paint, metal surface protective agent.

Crystalline Silica

Crystalline silica is composed of siliceous sandstone, quartz sandstone by metamorphism recrystallization and metamorphic rock. Siliceous cements of siliceous sandstone under the effect of geological conditions in the original quartz grain surface recrystallization, become increasing part of the quartz grains. Therefore, its structure is characterized by: composed of crystallization of quartz grains, quartz grains between no cement or rarely (3% ~ 8%); Made by metamorphic recrystallization in the process of quartz particles closely together, and do not constitute the original siliceous sandstone of blastic texture, such as sawtooth structure, the structure of the granite and Mosaic structure.

Cementing Silica

Cementation silica quartz particles were on the combination of siliceous cements of sedimentary rock, plastic structure is mainly secondary aphanitic quality quartz, usually account for about 30% ~ 75% cement content. Cementation of silica quartz crystal particles smaller, impurity content more, easy to change on heating.
