Chimney, desulfurization tower acid-resistant brick (glazed surface)
Size: T3 standard brick, 230*114*65 (size can be customized according to the drawing processing negotiation)
The main component of chimney acid-resistant brick is silicon dioxide, which is a substance with very high acid resistance. A large amount polyaluminum red corundum is formed by high-temperature sintering. Because the chimney acid-resistant brick structure is dense and has low water, it can also withstand any concentration of alkaline medium at room temperature, but it cannot withstand high-temperature molten alkali.
The content of dioxide in chimney acid-resistant brick is more than 60%, which is sintered. In the chemical industry, it is often used to build acid d, acid wells, acid storage tanks and load-bearing ground with large acid. The chimney acid-resistant brick is widely used in the chemical industry. The main is its acid resistance, light weight, which greatly reduces the weight of the overall structure, energy saving and environmental protection. Its characteristics are as follows: 1. has excellent chemical stability, strong acid resistance, and certain alkali resistance. 2. The size is smooth and smooth. 3. It is light in weight which greatly reduces the weight of the masonry structure and achieves energy saving and environmental protection.
