In the water-water plate heat exchanger, the hot and cold medium is non-corrosive to the rubber gasket. The key to the choice of rubber gasket material is temperature resistance and sealing energy. The rubber gasket material can be selected according to the literature.
Commonly used rubber seals gasket are adhesive and snap-on. The bonding type is to bond the rubber gasket with the glue in the sealing groove of the plate when the heat exchanger is assembled. The snap-on type is to fix the rubber gasket in the sealing groove of the plate by using a rubber seal and a snap-fit structure at the edge of the plate when the heat exchanger is assembled.Due to the small amount of snap-on installation work, the rubber gasket has a low damage rate when the heat exchanger is disassembled, and there is no chlorine ion which may be contained in the glue, which causes corrosion of the plate, so it is used more
