The performance Beer colloidal silica

Beer is an amorphous colloidal silica microporous structure of the solid powder, diameter 8-16nm, chemical formula mSiO2 · nH2O, Beer  colloidal silica insoluble in water and any solvent, in addition to caustic alkali and hydrofluoric acid, but not with any acid, alkali, salt from the reaction, non-toxic, odorless, nonflammable, non-explosive, with a strong heat, cold stability, harmless to human body.Beer  colloidal silica  mainly for the beer industry. 1 beer silica gel with a large specific surface area and porous structure of numerous appropriate, may cause beer turbid within a few minutes of protein adsorption, removed by filtration, thus prolonging beer storage period by 180-240 days, to prevent beer from being cold muddy. (2) does not affect the beer foam or taste. Beer physical and chemical nature of the  colloidal silicait has no effect on beer foam and taste, and practice has proved that beer colloidal silica is the world's beer industry recognized the safest beer stabilizer. 3 to improve to help filter effect. Beercolloidal silica  is chemically stable, non-beer soluble substances, the surface area and porous structure are much better than diatomaceous earth, is a good filter aid, diatomaceous earth filter aid to make beer brighter and more clear.Read more：http://www.chemical-chem.com/Papermaking-chemicals/Colloidal-Silica/
