Acid resistant brick
2.It has high acid-alkali resistance,low water absorption,is not easy to oxidize at room temperature and not be polluted by the medium and other properties.
3.In addition to hydrofluoric acid and hot phosphoric acid,it has excellent corrosion resistance to warm chlorinated brine,hydrochloric acid,sulfuric acid,nitric acid and other acids.
