Silica is the general name of white powder X-ray amorphous silicic acid and silicate products, mainly refers to precipitated silica, gas phase silica and ultra-fine silica gel, but also includes powder synthesis of aluminum silicate and calcium silicate. Silica is a porous material whose composition can be represented by SiO2·nH2O, which exists in the form of surface hydroxyl groups. It is soluble in caustic soda and hydrofluoric acid, but insoluble in water, solvents and acids (except hydrofluoric acid). High temperature resistance, non - flammable, tasteless, no smell, good electrical insulation.
Gas phase silica packing bag belongs to kraft paper composite packing bag
It is a packaging bag born under the guidance of improving packaging efficiency and convenient transportation. The overall appearance of the bag is square, which is very suitable for stacking transportation; The bottom of the valve mouth, easy to fill materials, and easy to seal. The new environment-friendly packaging for canning equipment can be divided into three layers of gas-phase silica packing bags or multi-layer gas-phase silica packing bags. In order to facilitate filling, holes can be punched in the bag body to facilitate gas discharge and prevent bag bursting during filling
