Do you know the reasons for vulcanizing effect of plate Vulcanizing Press Machine? Today, will give you an analysis, I hope to help you.
Several factors affect the performance and quality of the plate Vulcanizing Press Machine in the process of vulcanization, mainly the following three factors:
First, the amount of sulfur
Plate Vulcanizing Press Machine mechanical equipment of sulfur dosage the vulcanizing speed will be faster, the greater the sulfide program will be higher, but the sulfur solubility with rubber is limited, not sulfur usage, the better, the greater the excess sulfur by rubber surface precipitation, this phenomenon is called "sprayed sulfur", try to minimize sprayed sulfur, practice is in low temperatures, as far as possible Add the appropriate amount of sulfur, under normal circumstances, the amount of sulfur in soft rubber is not more than 3%, semi-hard glue is not more than 20%, the amount of pure hard glue is higher, more than 40%.
Two, vulcanization temperature
Vulcanizing temperature determines the vulcanization degree of uniformity, when high temperature 10 ℃, the curing time will shorten about half, and rubber are bad conductors, the vulcanization process will be different and different, because of its various temperature to achieve uniform effect of sulfide, thick rubber products of temperature control is critical, should be gradually heating up, vulcanization principle is low temperatures over long periods of time.
Three, curing time
Vulcanization time is an important link in the vulcanization process, if too short or to vulcanization procedure is not enough, commonly known as "sulfur:", too long when the degree of vulcanization will be too high, commonly known as "sulfur", only the appropriate length of time can achieve the vulcanization effect, commonly known as positive vulcanization.
