Refractory fiber materials: due to SW -30 acid silica sol sodium content is low, can withstand higher temperature, so can be used in the binder refractory fiber materials. Beverage adsorbent: adding acidic silicon solution to the beer after fermentation can make impure ions form condensate and be removed, making the product clear and bright. Can also be used for rice wine, soy sauce, fruit juice and other clarifiers, does not affect the product color, aroma, taste. And silicon is not toxic to humans. Electrostatic flocking: acid silica sol used in the static flocking technology, because the acid silica sol on the surface of the fiber formed silanase, and the fiber and hydrophilic to improve the electrical properties of flocking, it is the main component of electrostatic flocking agent, play a dispersing role. Lead acid battery: when used on dry colloidal Lead acid battery for acidic silica sol, it is mixed with sulfuric acid to form a silica gel which is an ideal non-mobile electrolyte for colloidal Lead acid battery, it changes the traditional Lead acid battery of acid leakage, pollution of the environment and the onerous operation of adding acid, adding water and maintenance, etc. , safe and reliable. Color Pleiades tube: acid silica sol for color picture tube and fluorescent screen manufacturing. Because of its good dispersibility and adhesion, it can be used as dispersant for color picture tube and screen.
