About rubber lining
Rubber lining is a method used to protect a variety of equipment systems against corrosion and scratches by applying rubber sheets inside or outside of the reuquested device.
Lining by natural rubber was applied to protect the surfaces’s equipment by America and European countries since the 1920s of the 20th century.
Nowadays, with the development of science and technology in the mixing and processing synthetic rubber and adhesives, rubber lining on the metal isconsidered as one of the most effective and successful applications in the protection of equipment against penetration, corrosion and abrasion.
In Vietnam, the anti-corrosion rubber lining has also been used by some chemical and food manufacturing plants since 1993.
Many Vietnamese enterprises have now approached and applied anti-corrosion rubber lining in industries such as electricity generation, steel production, petrochemical refining, mineral extraction, oil and gas, paper manufacturing, fertilizers, water, and environmental treatment to meet domestic production needs and exports.
Why rubber lining
Corrosion occurs when a metal is immersed in liquid which contains water or corrosive substances. Rubber Lining will solve the problem. Rubber lining provides excellent corrosion resistance by applying the rubber sheets onto the metal surface to protect the steel substrate from corrosive environment.
Rubber lining system
Rubber sheets shall be firmly bonded to steel substrate after application of primer and adhesive. After application of rubber sheets and proper vulcanizing, rubber lining provides rubber elasticity, superior strength and chemical reisitance.
Autoclave Vulcanizing (Curing)
The autoclave steam method involves placing the object(s) to be covered or lined with rubber inside a pressure vessel called an autoclave. The autoclave provides a carefully monitored flow of steam, which delivers the best control over the vulcanization process between the four basic curing methods and Good rubber properties and bonding by pressured steam curing.
It provides the increased rubber elasticity and stable physical properties.
