Product introduction of acid proof brick
Acid proof brick is made of quartz, feldspar and clay as the main raw materials by high temperature firing. Its main component is silicon dioxide, it is roasted at high temperature to form a large number of polyaluminum andalusite, is a kind of high acid resistance material.
Features of acid proof brick
- High acid resistance, low water absorption, good flatness; Beautiful, elegant style.
- It has impermeability, frost resistance, salt resistance, alkali resistance, weak acid corrosion resistance, and strong adhesion with a variety of materials.
- It can be constructed on the surface of wet substrate without drying and can be hardened in wet environment or underwater.
- Convenient operation and construction, similar to ordinary cement mortar construction, easy to clean.
- According to product drawings and technical data provided by customers.
Applications of acid proof brick
- Chemical industry: reaction tower, cooling tower, distillation tower
- Food dairy industry: fermentation, processing
- Environmental protection industry: sewage filtration, water purification and sanitation
- Non-ferrous metals: various industrial gas, waste gas treatment devices
