Acid proof brick is made of quartz, feldspar, clay as the main raw material, made by high temperature oxidation corrosion resistant materials, resistant to high pH, low water absorption, is not easy to be oxidized at room temperature, the media can not easily be pollution performance, except hydrofluoric acid and hot phosphoric acid, the temperature of chlorine saline, hydrochloric acid, sulfuric acid and nitric acid and at room temperature in any concentration of alkali, corrosion resistance are excellent.
The main component of acid resistant ceramic tile is silica, which forms a large amount of andalusite under high temperature calcination, which is a kind of material with high acid resistance. The acid proof brick structure, low water absorption, so at room temperature are resistant to alkaline medium at any concentration, but not resistant to high temperature molten alkali. Acid resisting brick contains more than 70% silicon dioxide, and is made by sintering. It is used in acid chemical ditch, acid well, acid storage storehouse and acid loaded big impact ground.
