Acidic refractories are a type of special refractories used in high temperature environments, mainly made of silicate, alumina, boric acid and other substances. Compared with other types of refractories, acid refractories have the following advantages.
1. Good acid corrosion resistance: acidic refractory materials use silicate as the main raw material, so they have excellent corrosion resistance in acidic environments. For example, in industrial fields such as copper smelting and zinc smelting, acidic refractory materials are widely used in the lining of equipment such as electrolytic cells.
2. Strong stability: Acidic refractories have high chemical stability, and can maintain stable physical and chemical properties even in high temperature and acid corrosion environments, thereby prolonging their service life.
3. Good thermal conductivity: Due to the high content of alumina in the acidic refractory material, its thermal conductivity is very good, which can help improve the heat transfer efficiency and thermal stability of the equipment.
4. Strong construction flexibility: The preparation process of acidic refractories is relatively simple, and can be constructed by pouring, spraying, masonry and other methods, and the ratio and performance of materials can be adjusted according to specific needs.
In short, acidic refractories have the advantages of good acid corrosion resistance, strong stability, good thermal conductivity and strong construction flexibility, so they are widely used in chemical industry, metallurgy, building materials and other industries.
