Introduction

The appearance of type z silica gel is white, transparent or translucent,Because its interior structure is a uniform microporous structure,the physical-chemical properties are stable, thermal stability is good and mechanical strength is high. Its average pore diameter is 8.0-12.0nm, specific surface area is 300-500m²/g, pore volume is 0.8-1.1mL/g, specific heat is 0.92KJ/kg·℃,and thermal conductivity is 0.167KJ/m·hr·℃.

Application

The product is mainly used in petroleum chemical industry catalyst preparation of molecular materials. Also it is widely used in the refined aromatic hydrocarbons removal of petrochemical products. In addition,it can also be used for selective adsorption of organic gases, liquids separation and the removal of many harmful elements of the water such as multivalence during the ion-exchange.
