Silica gel is received sodium silicate solution interaction with sulfuric acid or the sulfate aluminum containing free sulfuric acid with the subsequent washing and drying of the formed product.
Chemical formula: x SiO2 • n H2O
silica gel is applied as adsorbent to an osushka and purification of air as in after meshcheniye with big humidity, and the air given to compressors. For drainage of industrial and natural gases (carbon dioxide, hydrogen, oxygen, nitrogen, chlorine and others), for drying and clarification of some liquids Widely use silica gel for purification of various industrial oils. Also silica gel finds broad application in the industry (pharmacy, metallurgy, sewage treatment and dr).
As a moisture absorber silica gel is applied to protection from corrosion and from moisture at long storage of various substances, for example:
- details of cars, machines, etc. mechanical equipment;
- sukhozaryazhenny rechargeable batteries;
- various leather products (bags, footwear, etc. );
In double - glazed windows: in the bases of double - glazed windows silica gel for protection of fogging of windows is put.
Silica gel is widely used for production of fillers for cat's toilets.
KSMG silica gel
KSMG silica gel - Large Silica gel Finely porous Granulated. 3956 - 76 is issued in accordance with GOST. It is widely applied as a dehumidifier, especially at relative humidity of the environment
KSKG silica gel
KSKG silica gel - Large Silica gel Krupnoporisty Granulated. 3956 - 76 is issued in accordance with GOST. It is widely applied to an osushka. It is especially effective at the increased relative humidity (> 80% ). Also it is applied to purification of various industrial oils as the carrier for catalysts in chemical industry.
Indicator silica gel
Indicator silica gel – vypuksatsya in the form of fine grains from blue till dark blue color. Indicator silica gel is the same KSMG silica gel impregnated with cobalt salts. On a measure vpityvannnya moisture and decrease of the activity, a granule change coloring with blue to pink.
Packing, transportation and storage
Silica gel is packed into specialized soft containers of single use, into plastic bags or into the polyethylene bags inserts enclosed in paper bags. Silica gel is stored in the dry, closed warehouse in packing of the manufacturer.
