Metal anti-corrosion rubber lining technology and application scope
Thread Content
An anti-corrosion lining is an unvulcanized, pre-vulcanized, or vulcanized rubber sheet or plate used to prevent equipment from corroding. The technique of creating a continuous, isolating coating on the working surface of metals or other materials using lining rubber sheets is known as linering technology. Lining rubber compounds can be divided into soft rubber, hard rubber, and semi-hard rubber; they are generally manufactured using materials such as NR, CR, and SBR depending on the application conditions. The manufacturing of linings involves processes such as surface treatment of the metal substrate, processing of the lining adhesive sheet, cutting, bonding, and vulcanization. Lined rubber sheets are widely used as materials for chemical corrosion protection and mechanical wear resistance; they are employed as linings for chemical equipment, as well as for equipment in the mining and metallurgy industries such as slurry pumps, flotation machines, grinders, and cement mills in the building materials industry.
Metal anti-corrosion rubber lining technology: This technology involves applying a rubber layer (either unvulcanized rubber sheets, pre-vulcanized rubber sheets, or vulcanized rubber sheets) to the surface of metals or other substrates through bonding, thereby creating a continuous and dense protective layer that prevents corrosive agents from reaching the material and thus stops corrosion and wear of the metal. Main advantages: 1. Good resistance to chemicals and corrosive media. 2. It has good wear resistance and impact resistance. 3. It is flexible and can effectively resist stress damage caused by thermal expansion and contraction as well as mechanical vibrations. 4. It is possible to select adhesives with different performance characteristics based on the application environment (such as NR, CR, SBR, etc.). Application areas: 1. Chemical industry: Corrosion-resistant linings for reaction vessels, storage tanks, pipelines, valves, etc ； 2. Metallurgical mining industry: slurry pumps, flotation machines, mill linings ； 3. Power plant desulfurization system: Anti-corrosion and wear-resistant rubber lining for flue gas desulfurization towers, pipes, and accessories ； 4. Building materials industry: cement mills, mixing equipment, and silo linings ； 5. Environmental protection facilities: chemical waste liquid treatment equipment, waste acid storage tanks, sewage treatment equipment, etc ； 6. Ocean engineering and ships: Corrosion protection for seawater transfer pipelines, cooling water pipes, storage tanks, etc ； 7. Plating and electrolysis industries: protective linings for electrolytic cells, storage tanks, and acid and alkali transfer equipment. By selecting appropriate rubber compounds and carrying out precise processing, anti-corrosion lining technology can significantly extend the service life of equipment and reduce maintenance costs, thus holding great industrial application value. .
