Product introduction of Acid resistant refractory castable
High strength castable acid resistant castables refer to castable refractories that can resist the corrosion of acidic media (nitric acid, hydrochloric acid, sulfuric acid, acetic acid, etc.) in a high temperature environment of 800~1200 ℃. Refractory material acid resistant castable is an unformed material. Same as other unshaped refractories. Acid resistant castables can also be directly used in the project without burning. The acid resistant castables are not only highly plastic, but among many unformed materials, the production process of acid resistant castables is relatively simple, and they can be produced on the assembly line without special equipment. Moreover, the degree of mechanization is high, and it is easy to ensure that the quality is in a unified standard, with strong quality reliability.
Application of Acid resistant refractory castable
Acid resistant castables are widely used in metallurgical, petroleum, chemical, building materials, energy, machinery and other industrial kilns.
Advantages of Acid resistant refractory castable
The high strength acid resistant castable has the characteristics of small bulk density, fast solidification, high service temperature, compressive strength increasing with temperature and acidity, low thermal conductivity and low linear expansion coefficient.
