It-is chemically stable，flame-resisting，insoluble in any solvent except strong alkali or hydrofluoric acid．Superficial polarity，thermal stability，performance of adsorption and separation are all better than that of fine-pored silica gel．

With higher surface area and drying ability，the absorbent is being widely used in many fields. For its 

higher compression strength and lower rattier loss，it has longer life and higher performance-value ratio 

than fine-pored silica gel．As protective layer，about 20%(wt) is suggested when liquid water exits in the System

Water-resistent Silica Alu-Gel
Silica gel is a kind of high-active absorbing material, which is generally obtained by reaction of sodium silicate and sulfuric acid together with aging, acidic soaking and other series of post-processing. Silica gel belongs to amorphous substance and its chemical formula is mSiO2 . H2O. With stable chemical property, it won't burn and won't dissolve in any solvent except for alkali and hydrofluoric acid. Silica gels of various models form different fined-pore structures owing to different manufacturing methods. Additionally, the chemical components and physical structure of silica gel determine that silica gel owns many characteristics which can't be substituted by other materials of same kind, such as high absorption performance, excellent thermal stability, stable chemistry, high mechanical strength and others.

Product Description
Characteristics
This product is a water-resistant silica-alumina gel with fine pores. It is usually used as protective layer of fine-pored silica gel or fine-pored silica- alumina gel, and can be used solely when dissociated water(1iquid water)is in high content. Lower dew point can be true when liquid water exits in system.
Use
It is mainly used as drying agent for air-separation, compressed air and industrial gases, as ethyne absorbent for preparation of liquid oxygen or liquid nitrogen and as liquid absorbent or catalyst carrier in oil chemistry, electricity and brewery industry, especially used as protective layer of common silica gel and silica-alumina gel. About 20%(wt)should be the percent when used as protective layer.

insoluble in aides ( except for hydrofluoric acid) soluble in caustic alkali solution. compared with silica gel, it cotaines more hydrosyls and is a kind of high-purity reagent silica gel.

Use:

Mainly used for cjemial reagents, fusion agent for processing tungsten fulaments.

Techinical data:

Packing: 500 g net per plastic bottle.

Silica gel with fine pores includes spherical silica with fine pores and massive silica with fine pores. Spherical silica with fine pores has the appearance of colorless or yellow-transparent or translucent spherical particle, massive silica with fine pores is a colorless or yellow translucent glass-like irregular particle.

The average diameter is 2.0-3.0 nm, ratio surface area is 650-800 m2 / g, pore volume is 0.35-0.45 ml / g, ratio heat 0.92 KJ / kg. °C, thermal conductivity coefficient is 0.63 KJ / m. Hr.°C.

Mainly used as desiccants, moisture beads, agents to remove smell and all kinds of absorbents. Widely used to control relative humidity of the environment for storage and transport of instruments, meters, instruments equipment, leather, luggage, shoes, textiles, food, medicine and so on. It can prevent items from moisture, mildewing and rusting. Because of their high bulk density and obvious effect to absorb moisture in the case of low humidity, it can be used as air cleaner. They are widely used in the sea transport of ocean because the goods during transport often degenerate owing to temperature, the product can be used effectively to absorb water so that the quality of the goods is ensured.

Silica gel for Beer 

 Product information:

It is a kind of non-crystalline micro-porous solid powder,its pore diameter is 8-16nm.Its chemical molecular formula is mSiO2.nH2O,insoluble in water or any other solvent (except the caustic alkali and hydrofluoric acid). It does not react with any acid, alkali or salt. It is nontoxic, tasteless,flame-resisting and nonexplosive.It possesses high stability under hot or cold atmosphere and is harmless to human body,mainly used in beer industry.

usage:
1. It has large specific surface area and numerous fine-pored structure.It adsorbs the proteins which cause beer turbid and removes them through filtering,just within several minutes,thus prolonging beer storage period by 180-240 days and keeping beer from being cold muddy.
2. It does not affect the beer foam or taste.Thanks to its superior physical and chemical properties,it does not have any adverse effect on the beer foam or taste.It generally recognized by the world beer industry.
3. It helps improve the filter promoting effect.It is chemically stable,contains no beer soluble substances,Its surface area and porous structure are both superior to diatomite.It is a kind of ideal filter promoter in aiding diatomite filter,making beer brighter and clearer
