A subsidiary materials of corrosion prevention for chemicals

摘要

The present invention forms a highly corrosive chemicals and pipes, ducts and storage tanks for transporting and storing the gas, and particularly the inner wall to which the chemicals and the gas are in contact is relatively resistant to the corrosiveness of the contact material. Equipped with a highly corrosive synthetic resin, and the outer surface of the inner wall is provided with a mat-shaped glass fiber that is rolled and bonded by applying a heat deformation between 70 ℃ to 120 ℃ and then by forming an outer wall coated with FRP on the outer surface of the glass fiber It maximizes the corrosion resistance of pipes, tanks, and ducts that store and transport chemicals, and can also use products semi-permanently.
