the difference of the rubber gasket of plate heat exchanger

The rubber gasket for the plate heat exchanger is part of the heat exchanger, gasket material determines the maximum temperature of the plate heat exchanger and the pressure of the medium inside the plate heat exchanger under different working condition,In order to have a deeper understanding of the rubber gasket Performance and usage, there is a research which respectively analyzes the different rubber content of nitrile and EPDM rubber and FKM rubber, as well as the impact of different vulcanization systems on gaskets performance, the production and processing control of gaskets, and the analysis and quality of product defects. The reasons for sealing failure of plate heat exchanger and gasket.
The results show: nitrile rubber, EPDM rubber and FKM gasket rubber with higher proportion of raw rubber has better tensile strength, elongation and tear strength, especially the compression set performance comparing to the gasket with low rubber content; the performance of the gasket of the peroxide vulcanization system is better than the sulfur vulcanization system for different vulcanization systems with the same rubber content;The high temperature resistance of the gasket by FKM rubber bisphenol vulcanization system is better than that of the gasket obtained by the peroxide vulcanization system; the entire process of the production and processing of the gasket from mixing rubber to inspection and packaging will affect the quality of the gasket product. Carry out cause analysis in time and find targeted solutions. The reasons for unqualified products were analyzed, and the reasons for product failures such as the thickness of the gasket, the bubble defect, the gasket sticking off, the scorching defect, the non-melting of the material, and the gasket length fluctuation, etc.,were analyzed too, the product quality and pass rate have been improved by strengthening the production process control and quality control.we also should pay attention to plate heat exchanger maintenance in time .the gasket should be replaced immediately if heat exchanger leakage caused by gasket failure, In generally ,timely Maintenance can effectively extend service life of plate heat exchanger
