Acid resistant brick is a refractory brick with strong acid resistance and acid resistant bricks can be widely used in the industries. Acid resistant block is the ideal choose for your project with their features of proof pressure, corrosion resistance, easy to clean and acid base resistance. acid resistant blocks have dense structure, which can resist any pH indicator alkaline medium in the normal temperature, but not resist melting alkali in high temperature. acid resistant firebrick with over 93% SiO2 content, adopt silica as the main raw material and can resist acid furnace slag erosion. acid proof fire brick is mainly used in all kinds of furnaces and kilns with acid chemical component.
Main material of acid proof firebrick is quartz, feldspar and clay, acid proof refractory block is a kind of anti corrosive material by high temperature oxygenolysis. acid proof refractory brick has the characteristics of high acid resistance, low water absorption, not easy to be oxidized at normal temperature, not easy to be polluted by medium. except the hydrofluoric acid and hot phosphoric acid, acid proof fire block has excellent anticorrosive properties to wet chlorine, saline water, hydrochloric acid, sulphuric acid, hydrogen nitrate and other acid and the any concentration alkaline at normal temperature.
