Noncombustible Solid
Silica gel at -78 deg C adsorbs 4.5 wt % of ozone, and below this temperature the concentration increases rapidly. At below -112 deg C ozone liquefies and there is a potential explosion hazard at temperatures below -100 deg C if organic material is present.

Quartz (SiO2) Use and Manufacturing
In the sulfuric acid method, the diluted water glass and dilute sulfuric acid are mixed at 20 to 30°C to react to prepare the silicone gel, which is aged for 4 hours, soaked in 2% to 2.5% dilute sulfuric acid for 1 hour, washed with water at 40 to 50°C, Dehydrated in a drum dryer to a moisture content of ≤80%, dried to a moisture content of ≤10%, activated in an activation furnace at 500-550℃, and screened to obtain coarse-pored microsphere silica gel.
It is used in precision casting instead of ethyl silicate to reduce production costs, improve the operating environment, and improve product quality. Used as an adhesive for refractory materials and other materials. It is a coating material to prevent oxidation of certain products. As a coating material (inner and outer wall water-based paint) to improve adhesion, fastness, abrasion resistance, and stain resistance. As a synthetic fiber treatment agent to improve the friction coefficient of the fiber. As a sizing agent for warp yarns in the wool spinning industry, it can improve spinnability, hand feel, reduce flying hairs and end breaks, and increase production. Used in paper industry to improve paper smoothness and paper strength. It is also used as an abrasive, catalyst for the finishing of electronic materials, and as a coagulant for sulfuric acid in batteries.
Drug Function and Efficacy
This product is an oxidant. After being applied to the skin, it can slowly release new ecological oxygen, which can kill Propionibacterium acnes and has the effect of drying and desquamating the skin.
