Rubber conveyor belt vulcanization process needs to go through in order to be more strong and more durable, then what is the curing process it, today strongly to give us a presentation.
First, what is the curing process?
Vulcanization is conducted at a temperature, time and pressure, the rubber compound crosslinked linear macromolecules, the process of forming three-dimensional network structure.
Why conveyor belt vulcanizing process?
Vulcanized rubber, plastic lower, increase flexibility, the ability to resist external forces deform greatly increased and improved other physical and chemical properties, the rubber into a use value engineering materials.
Second, the conveyor belt vulcanizing process is mainly need to know:
1, the nature and curing factors affect the curing;
2, curing conditions to identify and implement methods;
3, vulcanizing machine operation methods, structures.
Third, do the conveyor belt vulcanization process to master the conditions?
1, vulcanizing machine two pressurized hot plate surface should be parallel to each other;
2, hot plate heated by steam or electric heating,
3, the plate in the curing process, the mold cavity area is not less than the pressure exerted on three MPa,
4, regardless of what type of hot plate, the temperature of the mold area should be evenly distributed,
5, the same hot plate between each point and the temperature difference between the center point and the maximum of once,
6, the adjacent two cubicles its corresponding position point temperature does not exceed once,
7, at the center of the hot plate is not more than 0.5 degrees maximum temperature,
Common technical specifications for the maximum closing pressure two hundred tons, piston stroke is two hundred millimeters, flat area of five hundred by five hundred millimeters, the working layer as a layer, the total heating power is twenty-seven kilowatts;
Fourth, the conveyor belt vulcanizing specific process?
Conveyor belt vulcanizing machine (single or double) with constant temperature segments vulcanized. Check before vulcanization good semi specifications, equipped with the appropriate thickness of the horn and the top rail with embryo dragged stretched flat space required, the plate from the top with low pressure, high pressure pulls the top tight, according to process standards vulcanization conditions specified. |
