Heat Exchanger Plates And Gaskets
The plate heat exchanger is a new type of high efficiency heat exchanger which is assembled by a series of metal sheets with a certain corrugated shape.The joint surface of the plate heat exchanger should be cleaned with a chemical cleaner, for example with acetone. Also, chemical cleaners must be used to remove the softener and anti-blocking coating that is bonded to the gasket. The adhesive is applied to the middle of each of the bonded bonding faces. Depending on the width of the gasket, the width of the adhesive is approximately the width of a match, and then the adhesive is applied evenly over the entire bonding surface with a brush to take full advantage of the entire bonding surface. Depending on the type of adhesive, wait for a certain ventilation and drying time, then put in a gasket, stack the various plate heat exchangers together, tighten with a tensioning screw, or press the heavy object on the stack. On the heat pack. The hardening time is about 8 h to 20 h depending on the type of binder. For blending adhesives, screw tightening and furnace hardening must be performed.
