Plate heat exchanger gaskets are extremely critical components of gasket plate heat exchangers. The application range of plate heat exchangers is also largely limited by gaskets, which are used in highly corrosive media. The requirements are extremely high. Due to the expanding application of plate heat exchangers, different temperatures, pressures and corrosion resistances are required for different media and processes. It is obviously impossible to use a "universal" gasket to adapt to all situations, but different materials should be used for different situations. Commonly used gasket cross-sectional shapes are six-sided rows. Commonly used types of heat exchanger gaskets include natural rubber, neoprene, EPDM rubber, silicone rubber, fluoro rubber, and asbestos fiberboard. If the gasket of the plate heat exchanger is leaking, broken, aging during use, it should be replaced in time. How to replace the gasket of the plate heat exchanger?
(1) Remove the used gasket. Be careful not to scratch the gasket groove when disassembling.
(2) Remove the residual glue in the gasket groove with acetone, methyl ethyl ketone or other ketone solvent.
(3) Wipe the gasket groove and gasket with a clean cloth or cotton yarn.
(4) Apply the adhesive evenly to the gasket groove.
(5) Attach a clean new gasket to the board.
(6) The phe plates with the gaskets should be placed in a flat, cool, and ventilated place for 4 hours before they can be installed and used
