性状 
啤酒硅胶是一种非晶态多微孔结构的固体粉末,孔径为8-16nm,化学分子为式为mSiO2·nH2O,不溶于水和任何溶剂,除苛性碱和氢氟酸外,不与任何酸、碱、盐起反应。无毒、 无味、不燃烧、不爆炸,具有强的热、冷稳定性,对人体无害。主要用于啤酒工业。
用途
1.啤酒硅胶具有大的比表面和无数适宜的微孔结构,可以在几分钟内把造成啤酒浑浊的蛋白质吸附,经过滤除去,可延长啤酒贮藏期180-240天,防止啤酒出现冷浑浊。
2.不影响啤酒泡沫和口味。啤酒硅胶的物化性质决定了它对啤酒泡沫和口味毫无影响,实践也证明了啤酒硅胶是世界啤酒行业公认的最安全的啤酒稳定剂。
3.提高助滤效果。啤酒硅胶化学性质稳定,不含啤酒可溶物,其表面积和多微孔结构均大大优于硅藻土,是很好的助滤剂,辅助硅藻土过滤能使啤酒更明亮、更清澈。

Characteristics
Silica gel for Beer is a kind of non-crystalline micro-porous solid powder, its pore diameter is 8-16 nm. 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.
Use
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 is justified through practice that beer silica gel is the safest beer stabilizer 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.
