Acid resistant ceramic brick and plate
Acid resistant ceramic is widely used in the fields of petroleum,chemical engineering,pharmacy,food, paper making,fertilizer,pesticide,chemical fibre,textile,smelting,electricity plant.It can act as anti-corrosive lining in the tower,pool,can and trough,and play its anti-corrosive role in the working field of sewage treatment project and outdoor ground.Acid resistant ceramic can resist most medium except hydrofluoric acid,hot phosphorus and high concentration alkali.It can maintain excellent anti-corrosive function not only to wet-chlorin brine, hydrochloric acid, sulphuric acid,nitric acid and other acids,but also to any concentration alkali under normal temperature.
