Product description of acid resistant castable
The price of acid resistant castable is low compared to that of resistant organic materials. In addition to the equivalent corrosion resistance properties of organic acids, it also possesses unique corrosion resistance properties in oxidized medium.
Features of acid resistant castable
The characteristics of acid resistant castable are low volumetric density, fast solidification, high operating temperature, improved pressure resistance as a function of temperature and acidity, poor thermal conductivity and weak swelling coefficient.
Applications of acid resistant castable
In metallurgy industry, petroleum, chemical industry, building materials, electric power and machinery industry and other industrial furnace widely used by acid resistant castable, compared with other amorphous castable, acid resistant castable liquidity is better, so it is easier to construction and easier to achieve the ideal construction results, at the same time because of the higher binder and moisture, in the fire prevention is very prominent, Therefore, acid-resistant castable also has good high temperature resistance.
