We promise to provide you with high-quality refractory materials.
Product introduction of acid proof brick
Acid proof bricks/acid resistant bricks are corrosion-resistant and acid resistant materials, which are mainly made of quartz, feldspar and clay and fired at high temperature.
Acid proof bricks have many good properties, such as high acid resistance, high density, low water absorption, good corrosion resistance, and are not easy to be oxidized and polluted at room temperature.
Acid proof bricks can resist most acids, such as warm chlorine salt water, hydrochloric acid, sulfuric acid, nitric acid, except hydrofluoric acid and hot phosphoric acid. It can also resist alkali of different density at room temperature.
Application of acid proof brick
Acid proof bricks are widely used in chemical industry, such as anti-corrosion linings for workshops, outdoor acid resistant floors, towers, tanks, sinks, etc.
Features of acid proof brick
High acid resistance, low water absorption, smooth surface, accurate size.
Permeability resistance, frost resistance, salt resistance, and good adhesion with other materials.
It can be installed on wet surfaces without drying, and can be hardened in water or wet environment.
Easy to install and clean.
It can be customized according to customer drawings.
