Plate Heat Exchanger Gasket Types
The sealing of the gasket is divided into two categories: adhesive fixing and non-bonding fixing. The gasket shape should be consistent with the shape of the plate heat exchanger seal. It must be pointed that the adhesive fixing method does not have any effect on the sealing function.
1.Non-bonded seal (1)Alignment: Place the seal in place(2)Put in: make the sealing ring enter the sealing groove correctly (3)Compression: In the sealing groove, there is a trough structure with a gradually decreasing cross section to position the sealing ring
Depending on the purpose and the quality of the seal, blending sealants and non-harmonic sealants from different manufacturers can be used. Before bonding, a vapor stream should be used to remove the adhesive remaining on the bonding surface and the residual gasket. For blended sealant bonding, the residual adhesive and residual gasket on the phe bonding surface must be burned out. When bonding in large quantities, the liquid nitrogen tank of the frozen seal should be prepared and prepared as a plate heat exchange gasket with a gasket. When bonding in large quantities, the liquid nitrogen tank of the frozen seal should be prepared,and the heating furnace for drying the plate heat exchanger with gasket should be prepared. The heating temperature should be 160 ° C. If conditions permit, the plate should be prepared. The heat exchanger is chemically cleaned to ensure complete removal of the gasket of the bond remaining in the bonded surface of the plate heat exchanger.If possible, the plate heat exchanger should be chemically cleaned to ensure complete removal the gasket bond remaining in the joint surface of the plate heat
