The plate heat exchanger is a high-efficiency heat exchange device composed of a plurality of corrugated heat transfer plates at a certain interval by welding or pressing by a rubber gasket. According to the processing technology, it is divided into a detachable heat exchanger and a fully welded non-removable heat exchanger. The welded heat exchanger is a structure between the two, that is, the two fluids are assembled as relatively independent structures.
Plate heat exchanger gaskets are extremely critical components of detachable plate heat exchangers. The application range of plate heat exchangers is also largely limited by rubber gaskets.The requirements are extremely high in highly corrosive media.The phe gasket of the plate heat exchanger is an important part, which has an important influence on the service life of the plate heat exchanger. If these gaskets harden and lose the proper elasticity, the heat exchanger may not operate normally.
