Light Acid Resistant Castable Introduction
Light acid resistant castable produced by Rongsheng Refractory has good physical and chemical properties, has small bulk density, fast water solidification, high use temperature, and the compressive strength increases with the increase of temperature and acidity, the thermal conductivity is small, and the coefficient of linear expansion is small. Due to the above mentioned high quality properties of lightweight acid resistant refractory castables, of course, the requirements for transportation and warehouse management are relatively high. We are professional refractory castables manufacturers, and will put aggregate and powder in the light acid refractory castables when they leave off the factory. The refractory material is mixed into a mixture and transported in a woven bag for transportation. It is temporarily stored in a dry warehouse with good drainage measures and protection from rain and moisture.

Light Acid Resistant Castable Application
Light acid resistant castables are mainly used for anti corrosion flue and chimney lining, acid storage tank, pickling tank lining, nitric acid concentration tower lining, acid recovery furnace lining and other container linings corroded by acidic high temperature gas.
How to Use Light Acid Resistant Castable
1. Acid resistant castables should not be used alone in particularly humid environments. Because refractory castable itself has excellent fire resistance but its poor penetration resistance, it is not suitable for use in humid environments. If it is necessary to use it, it is necessary to lay a layer of waterproof material before use.
2. It is best not to use it as a separate refractory material. Acid resistant castables have excellent fire resistance, but they are likely to break the bond of acid resistant castables when used directly in high temperature environments because of their own characteristics. Therefore, there should be a layer of insulating felt when used as refractory material.
