The use of EPDM reclaimed rubber conveyor belt produced high temperature resistance, aging resistance, corrosion resistance, a wide range of applications, especially long-term exposure to the conveyor belt products outdoors. Including the conveyor belt, including all rubber products in the production process can not be separated from a process - vulcanization, vulcanization process directly affect the performance of rubber products. Among them, the curing time is an important parameter, then the EPDM reclaimed rubber production conveyor belt, vulcanization time is how to affect the conveyor belt performance? How to determine the best curing time?
The use of EPDM reclaimed rubber production rubber conveyor belt, there are many factors that affect the vulcanization time, such as the type and amount of vulcanizing agent in the vulcanization system, accelerator usage, vulcanization temperature settings, etc. In addition EPR rubber conveyor belt The length of vulcanization also has a direct relationship with the thickness of the product.
Under normal circumstances, EPDM reclaimed rubber production conveyor belt curing system, the greater the amount of curing agent, the shorter the curing time required; the higher the curing temperature, the shorter the curing time, the vulcanization temperature is usually increased by 10 ℃, vulcanization Time can be reduced by half (here need to pay attention to the high curing temperature will cause cracking of the rubber molecular chain, resulting in the physical and mechanical properties of EPDM reclaimed rubber, so the conditions allow the appropriate increase in the curing temperature to shorten the curing Time. EPDM curing temperature vulcanized rubber between 150-170 ℃); EPDM conveyor belt thicker, the longer the curing time, under the condition of one-sided heating curing vulcanized conveyor belt for each additional 1mm, Vulcanization time increased 12min, double-sided heating conveyor belt for each additional 1mm, vulcanization time increased 5min; season temperature will also affect the EPDM conveyor belt vulcanization time, the general production of conveyor belt in summer when the curing time required is shorter than in winter .
In short, the use of EPDM reclaimed rubber production conveyor belt products, the best curing time can not be generalized, even if the same product with the same performance, it's curing time is also different.
