 USING SCOPE OF CORROSION RESISTANCE RUBBER LINING
Rubber has good resistance to chemical corrosive performance, it has good adhesive force for making iron, steel, nikel, chromium and brass. It also has advantages of good elasticity,resistance to impact and abrade.
Rubber is widely used in factory,traffic transfer department, which can be used to store medium and it canbe be touched to the rnetal equipments that made by acid、alkali、salt and so on;  it is also used to resistance to easy corrosive chemical medium etc.
The rubber lining is used for various water treatment equipment, such as anion and ration switch、Na- swith、acid and alkali gauge, storage tank, tank car, agitator etc,the performance is in corformity with the standard of Chemical Equipment and Rubber Lining of Pipe Fittings which is is used byChina Chemical Department, the hard rubber and half rubber should be used in the temperature of 85
