when ordering a volume of 100kg - 35grn / kg

Silica gel is a translucent or chalky white or yellow corn (from impurities) color, in the dried state is brittle, slightly soluble or swell in water and organic solvents. This dried gel formed from supersaturated solutions silicas. Hard hydrophilic sorbent.

The structure of the silica gel is a highly porous body formed by tiny spherical particles, it has a huge surface area, chemical composition - silicon dioxide SiO 2 (silica).


Chemical formula: xSiO 2 • nH 2 O

It is obtained by acidification of alkali metal silicate solutions, followed by washing and drying the resulting gel.

Product silica produced in the form of spherical grains or granules. Different grades of silica have an average effective pore diameter of 20 - 150 Angstroms (1 Angstrom = 10 - 10 m) and a specific surface area of 100 - 1000 m² / g.


Silica gels are distinguished:

- Shaped grains (granular or lumpy);
- Grain size (large and small);
- Pore size (large pore and small pore).


Depending on the size distribution, particle shape and character of porosity - silica four letters denote:

1 - describes the size of the granules (C - major, M - shirt, A - activated, W - leads charge);
2 - Always On (silica);
3 - pore size (K - a coarse, F - fine pore);
4 - particle shape (D - granulated, K - lumpy).


The use of silica gel.

For air drying:
a) in areas with high humidity;
b) the air supplied to the compressor.
For drying carbon, hydrogen, oxygen, nitrogen, chlorine or other industrial gases.
For the dehydration of natural gas.
As a desiccant to protect against corrosion from moisture during prolonged storage of various substances, for example:
- Machine parts, machine tools and other mechanical equipment.
- Dry - cell batteries;
- Optical instruments;
- Leather, various leather goods (bags, shoes, etc. );
- Food products.
In aviation, silica gel desiccant is applied in cartridges that are installed in the space between glass panes of aircraft cabins.
The double - glazed windows: insulating glass in the grounds laid gel for the prevention of fogging of windows.
For dehydration of various liquids, particularly in the case where the liquid poorly dewatered dissolves water, for example, in refrigeration dewatering freon.
Silica gel adsorbs well pair polar substances, such as acetone, alcohols, ethers, benzene. This property it used to capture (recover) the vapors of organic compounds, such as benzene from coke oven gas, gasoline from natural gas.
For purification of various industrial oils.
For the drying and purification of oil distillates and oil sludge.
Widely used in chromatographic analysis for separating and analyzing mixtures.
In the pharmaceutical industry for concentrating and isolating antibiotics from the culture medium.
For sorption of platinum metals.
As catalyst (accelerator) of many organic reactions.
As a carrier for catalysts. Silica gel used as a carrier of a wide variety of catalytically active substances.
As ion exchangers:
- For the separation of radioactive isotopes;
- Treatment of industrial waste water from ions of various metals;
As a health care facility with intoxication (poisoning) radioactive substances.
