Compared with common curing system, peroxide curing system has a higher temperature coefficient, and the curing speed is twice as fast for every 10 ℃ increase; The common curing system has poor high temperature resistance and large compression set.
In the production process of plate heat exchanger gasket, vulcanization is an important link. The quality of vulcanization directly reflects whether the performance of plate heat exchanger gasket is stable. The vulcanized rubber has high elasticity, high temperature resistance, tensile strength and is insoluble in organic solvents. Most products are vulcanized rubber, including sealing gaskets of plate heat exchangers.
Due to the characteristics of rubber itself, it is softened by heat, hardened and brittle by cold, difficult to form, easy to wear, easy to dissolve in organic solvents such as gasoline, and easy to age. In order to improve the performance of rubber products, vulcanization production should be carried out in production. The rubber in the rubber compound will react with the curing agent under certain conditions, so that the rubber compound has high strength, high elasticity, high wear resistance, corrosion resistance and other properties. During the curing process, the high temperature resistance, medium resistance, aging resistance and physical and mechanical resistance are improved.
There are two vulcanization systems in the production process, one is sulfur vulcanization system, the other is peroxide vulcanization system (non vulcanization system). The gasket of the plate heat exchanger produced by the latter has good chemical stability, excellent thermal oxygen aging resistance, small permanent deformation of vulcanizate, good elasticity, poor dynamic property, and curing time is 6-10 times longer than the former.
Compared with common curing system, peroxide curing system has a higher temperature coefficient, and the curing speed is twice as fast for every 10 ℃ increase; The common curing system has poor high temperature resistance and large compression set.
