Acid resistant ceramic tiles are ceramic materials mainly made of quartz, feldspar, and clay, which are fired at high temperatures. They have high acid and alkali resistance, low water absorption, are not easily oxidized at room temperature, and are not easily contaminated by media. In addition to hydrofluoric acid and hot phosphoric acid, they have excellent corrosion resistance to acids such as sulfuric acid, hydrochloric acid, nitric acid, and any concentration of alkali at room temperature. They are widely used in the anti-corrosion lining of towers, tanks, tanks, and other equipment in industries such as petroleum, chemical, smelting, electricity, chemical fiber, papermaking, pharmaceuticals, electroplating, and environmental protection, as well as the laying of block materials in building anti-corrosion areas such as floors and ditches.
