high temperature acid proof bricks Acid resistance of 99.8% Water absorption below 0.2% Bending strength beyonds 58.8 Mpa
Acid resistance bricks and boards are widely used in drying,absorbing and reactor in metallurgical,chemical and petrochemical.It also can be used for lining in antiseptic pool,floor and passageway.
Acid resistance pipes are used for lining in different kinds of furnaces,troughs,towers and mixing pool in metallurgical,chemical and petroleum industries.
