We are a refractory material manufacturer, with four major factories: heavy brick factory, light brick factory, monolithic refractory factory and fused-cast brick factory.
We promise to provide you with high-quality refractory materials.
Product introduction of acid proof brick
Acid proof bricks are mainly made of quartz, feldspar and clay, and calcined at high temperature as anti-corrosion and acid resistant materials. Due to its compact structure and low water absorption, acid resistant bricks can also resist various concentrations of alkaline media at room temperature, but cannot resist high-temperature molten alkali.
Features of acid proof brick
High acid resistance and low water absorption
Resistance to penetration, freezing, salt, alkali and weak acid corrosion
Applications of acid proof brick
- Chemical industry: reaction tower, cooling tower, distillation tower
- Non ferrous metals: various industrial gas and waste gas treatment plants
- Electronic industry: waste gas treatment devices for semiconductor and other production processes
