The main component of acid-proof bricks is silicon dioxide, which, upon high-temperature firing, forms a large amount of andalusite, a highly acid-resistant material. Due to the dense structure and low water absorption rate of acid-proof bricks, they can withstand any concentration of alkaline medium at room temperature, but are not resistant to high-temperature molten alkali. These bricks contain over 70% silicon dioxide and are sintered. They are widely used in the chemical industry for lining acid channels, wells, storage tanks, and heavily impacted surfaces carrying acids.

Our products have high acid resistance, low water absorption, and excellent flatness. They feature resistance to seepage, freezing, salinity, alkali, and mild acid corrosion, and possess strong bonding power with various materials. They can be applied on damp substrates without drying, hardening in moist environments or underwater. The operation and construction are convenient, and they are compatible with ordinary

Easy to clean, can be washed with water. Production can be tailored according to the customer-provided product drawings and technical documents.
