2Mm 3mm 4mm 5mm Refractory Products Pre Vulcanized Butyl Rubber Lining
Presulfuration or self vulcanized butyl rubber produced by our company, the biggest advantage is to overcome the heat vulcanized rubber lining can not apply to large equipment and on-site construction defects, with corrosion resistance, strong adhesion and good extensibility, no delamination, overcomes the shortcomings of variant and internal stress of metal. Applicable to sulfuric acid, hydrofluoric acid and hydrogen silicate etc. various concentrations of acid and various organic solvents and acid salts and the mixture of different medium, widely used in petroleum, chemical, metallurgy, pesticide, fermentation, hydrolysis, acid and other industrial reactor, storage tank, tower, pool, floor and ditch, electrolyzer, the high temperature corrosion of chimney and flue equipment anticorrosion engineering. It is an excellent anticorrosive lining material in chemical industry, pharmacy, nonferrous metallurgy, food processing and so on.
Our company is uniquely equipped with lining technology of pre vulcanized rubber sheet. It improves the traditional lining process and the internal stress modification of metal. It does not take off the layer and has strong adhesive force. For many years to undertake all kinds of equipment anti-corrosion lining project, trusted by customers.
