The curing methods of EPDM sealing strip can be divided into discontinuous curing method and continuous curing method. The specific analysis is as follows:

(1) Discontinuous vulcanization of EPDM sealing strip (cutting length of tape after extrusion, placing it in a autoclave, extruding sulfur compounds of rubber semi-finished product model);

(2) Continuous vulcanization (microwave continuous vulcanization, salt bath continuous vulcanization, continuous hot air vulcanization and other methods).

A. Microwave continuous vulcanization of compound sealant strip: the production process of microwave continuous vulcanization includes metal core, dense rubber and extruded foamed plastic materials and energy. The efficiency of continuous vulcanization equipment is better than other equipment. Technology has squeezed products to produce the best way in the world. Microwave heating is the feature of the heated object, a little like the conventional input from the outside, not only heating and distribution, by improving the product quality, the heat generated shortens the time required for heating.

B. Continuous curing sealed salt bath: the bath salt bath contains sulfide and nitrite system, which causes greater environmental pollution and is gradually eliminated.

C. Hot air vulcanization seal: hot air vulcanization has developed into a strong wind with high temperature, which can achieve high speed and hot air vulcanization (Vmax: 60m / s and Tmax: 450 ° C). The effect of using pretreatment can greatly improve the safety.
