What is the appearance of the rubber board after vulcanization?
The powder is a curing agent, accelerator, activator, antioxidant and filler powder with precipitation agent on the rubber surface, and form a layer of powder spray wax is paraffin wax, ceresin wax precipitation etc. on the rubber surface, forming a layer of wax. The injection is softening agent, thickening agent, lubricating agent, plasticizer, etc. with the liquid agent precipitation on the rubber surface, and form a layer of oil.In practice, the form of frost on the surface of rubber sometimes appears in one form, sometimes in two or three forms
Fuel injection, blue or white! I also spray cream! Before production of recycled plastic sheet and synthetic rubber had similar problems, the need for specific advice, private letter to contact Baidu!Rubber unvulcanized rubber (hereinafter called rubber) and vulcanized rubber (hereinafter called products) of the points, including rubber rubber spray cream frosting and product surface spray frost. Frost spray (Bloom) is a liquid or solid rubber compounding agent by internal migration to the surface of the rubber rubber compounding agent internal visible phenomenon the precipitation is formed on the rubber spray frost. Frost spray form summed up can be divided into three kinds. The spray, spray wax, fuel injection (also called exudation).
Rubber spray frost is due to internal rubber compounding agent reachsupersaturation, rubber compounding agent near surface precipitates first, then from the inner to the surface migration of precipitation when complexing agent in the rubber to reduce its saturated state, precipitation process ended. The agent of reachsupersaturation, main causes of rubber injection cream: rubber formula design process properly, improper operation, raw material quality fluctuation, poor storage conditions, products, products less sulfur and aging.
