Chemical properties:
Diatomaceous earth is a transparent to gray,odorless amorphous powder.
pH value
5-8 (100g/l, H2O, 20ºC)(slurry)
Physical properties:
Hard glassy transparent or semi-transparent particles, with an average particle size of about 5mm. It has characteristics such as porosity and large specific surface area. It has a strong adsorption effect on water vapor at a relatively low humidity. It has selective adsorption properties for certain harmful substances in the medium. Due to its spherical shape, smooth surface and high mechanical strength, it is not easy to break and has low resistance. Insoluble in water and inorganic acids (except hydrofluoric acid), but soluble in caustic alkali solutions.
Solubility
insoluble | Grams dissolved per 100 milliliters of water: 1.2×10-2/20ºC
Stability
After absorbing moisture, it forms polymerized fine particles. It has a very high insulation property.

2. Does not decompose at high temperatures. It has water absorption. It shows chemical inertness to the matrix, active ingredients and additives. It has good compatibility with many active ingredients commonly used in vitamins, hormones, fluorides, antibiotics, enzyme preparations and cosmetics. Due to its porosity and large specific surface area, it has a relatively strong dispersion force in raw rubber. It shows high reinforcing properties when filled in rubber. Stimulating. The coefficient of thermal expansion is low.

3. It can form soluble silicates with molten caustic alkali or carbonate alkali.

 

Application

It is widely used in industries such as metallurgy, refractory materials, chemical engineering, abrasives and construction;
 

About 70% of silica is used as a reinforcing filler for natural and synthetic rubber. The rest is used as a filler for synthetic resins, a thickener for inks, an anti-settling agent for pigments in coatings, a matting agent, a soft polish for vehicles and metals, and an anti-settling agent in emulsifiers. It can also be used as a carrier for pesticides and a filler for lightweight newsprint. Due to the advantages of silica fume such as good electrical insulation, low heat generation, light product color and no pollution, it is also widely used in rubber hoses, rubber belts, heat-resistant gaskets, rubber rollers and medical products. ;

It is used as a filler for color TV cables, wire conduits and rubber transparent bottoms. It is also used as a thickener, thixotropic agent, anti-settling agent, matting agent, plastic release agent, liquid drug adsorbent, cosmetic and papermaking filler. ;
 

As an anti-caking agent, it is stipulated in China that it can be used as a powder flavoring agent, with a maximum usage of 80g/kg. It can also be used in milk powder, cocoa powder, egg powder, plant-based powder and instant coffee, etc., with a maximum usage of 15.0g/kg.

It is used as a reinforcing agent for rubber, an opening agent to prevent plastic film adhesion, an anti-settling agent for pigments, a matting agent for coatings, a viscosity regulator, an excipient for pharmaceuticals, a catalyst carrier, and in cosmetics, etc. ;
 

Anti-caking agent Suspension agent Defoamer Carrier Thickener Filter AIDS, clarifying agents, and adsorption and drying agents for flavors and fragrances in wheat extract beverages, fruit wine, soy sauce, vinegar, and refreshing drinks. GB 2760-90 stipulates it as a processing aid;

It is used as a reinforcing filler for natural rubber and synthetic rubber, a filler for synthetic resins, a thickener for inks, an anti-settling agent for pigments in coatings, a matting agent, a soft polishing agent for vehicles and metals, and an anti-settling agent in emulsifiers. It can also be used as a carrier for pesticides and a filler for lightweight newsprint. ;
 

It is used for bonding between glass planes such as picture tubes, projection tubes, and sight tubes and phosphors. ;
