Brief Introduction
Acid Resistant Castable is a kind of granulous and powder material made with certain content of bindingagent added in fire-resisting materials. Acid Resistant Castable has high liquidity and is suitable for unshaped refractory materials made with pouring type. Acid Resistant Castable has various features of high temperature resistance, high mechanical strength and strong acid erosion resistance for all kinds of furnaces and kilns application.

Application
Acid-resistant castables are divided into heavy, semi-light and light, and their main function is to be used for furnace linings resistant to acid corrosion. Acid-resistant castables are generally combined with acid-resistant cement, and are applicable to acid-resistant chimneys and liquid sulfur tank linings in the petrochemical industry.
