Production Process Of Plate Heat Exchanger Gaskets

The plate heat exchanger is a high-efficiency heat exchanger made up of a series of metal sheets with a certain corrugated shape. The plate heat exchanger gasket plays a very important role in the entire heat exchange system. Many companies only pay attention to production, but do not pay attention to production technology. Many customers suffer from aging and Production process of plate heat exchanger gasketscorrosion of gaskets after buying it. What is the production process of the gasket for the plate heat exchanger?

Plate heat exchanger pads are a relatively complex polymer system, usually composed of rubber polymers, vulcanizing agents, fillers, antioxidants, processing aids, and thinners. Although the processing aids cannot extend the life of rubber gaskets, they are very effective in improving the mixing, extrusion and molding functions in the production process of gaskets. The selection of original materials and their ratios will determine the rubber gasket’s performance. Quality function.

Natural rubber is made from the latex of the Hevea tree, and its basic chemical composition is cis-polyisoprene. Isoprene rubber is a high cis composition rubber made from isoprene. Because its structure and function are similar to natural rubber, it is also called natural rubber.SBR is made by copolymerization of butadiene and styrene. It is divided into emulsion polymerization SBR and solution polymerization SBR according to the production method.Butadiene rubber is made by polymerization of butadiene. After vulcanization, butadiene rubber has excellent cold resistance, abrasion resistance and elasticity, less heat under dynamic load, and good aging resistance. It is easy to use with natural rubber, neoprene rubber and nitrile rubber.
