EPDM sealing strip curing method
EPDM sealing stripCuring methods can be divided ︰
（1） EPDM sealing stripNon-continuous vulcanization method (after extrusion of cut lengths of tape, placed in an autoclave, extruded rubber semi-finished products model of sulfur-containing compounds);
2) Continuous vulcanization (microwave continuous vulcanization and salt bath continuous vulcanization, continuous hot air vulcanization and other methods).
A. microwave continuous vulcanization composite sealant strip: microwave continuous vulcanization production process includes metal core, dense rubber and extruded foam plastic materials and energy, improve efficiency, continuous vulcanization equipment is better than other. Technology has been the best way to produce extruded products in the world. Microwave heating is a feature of the object being heated, somewhat like conventional input from the outside, not only heating and distribution, by improving the quality of the product, the amount of heat produced shorting the time required for heat.
B. Continuous curing sealing salt bath: Bathing salt bath containing sulfide nitrite system, greater environmental pollution, gradually be eliminated.
C. Hot air vulcanization seal: Hot air vulcanization has developed into a strong wind, high temperature, can achieve high speed and hot air vulcanization (Vmax:60 m/s and Tmax:450 ° c), the effect of using pretreatment, while greatly improving the safety.
