Ceramic acid-proof bricks: Excellent acid resistance for flooring & walling, High strength & low water absorptio

Ceramic acid-proof bricks and tiles have very excellent acid resistance and high temperature resistance. They can withstand violent heat and cold, and they are used in kinds of chemical conditions as flooring and lining.

Application: 

Acid resistant ceramic bricks are used as inner lining for drying, absorption,tower and reactor in chemical plant,chemical fertilizer plant and sulfuric acid plant or used as inner lining for anticorrosive pools and channels and covered the anti acid ground etc.

 

Features: 1) Ceramic acid-proof bricks and tiles:a) Very excellent acid and alkali resistanceb) High temperature resistancec) Can withstand violent heat and coldd) Used as flooring, lining in many kinds of chemical reactors, towers (includingdrying towers and absorption towers), and tanks of acids and other chemicals in chemical factories, fertilizer factories, sulphuric acid factories and iron and steel factoriese) Also used as lining of antiseptic pools and ditches2) Ceramic self-supporting domes:a) Very excellent acid and alkali resistanceb) High temperature resistancec) Widely used as bottom supporting media for many chemical towers (such as sulfuric acid towers, drying towers and absorption towers) and many chemical reactorsin chemical factories, fertilizer plants and sulphuric acid plants

The products are used as inner lining for drying, absorption, tower and reactor in chemical plant, chemical fertilizer plant and sulfuric acid plant or used as inner lining for anticorrosive pools and channels and covered the anti acid ground etc.
