Hot vulcanized rubber slurry is widely used for vulcanization bonding of various rubber conveyor belts, steel core conveyor belts, whole core conveyor belts, nylon, canvas, and polyester conveyor belt joints, especially suitable for conveyor belt joints.
Surface treatment: Make the conveyor belt joint into a diagonal stepped lap joint with a lap length of 1/2 of the bandwidth, then roughen the surface of the joint and use cleaning agent to clean and dry it.
Gluing: Apply a layer of vulcanized adhesive evenly on the surface of the joint and vulcanized film, wait for the solution to evaporate until the adhesive surface is basically dry, and then attach the vulcanized film to the surface coated with sulfur
Melt the surface of the adhesive joint, then close the joint and apply pressure, heat and vulcanize it.
Pressure: Press the two heating plates tightly on and off the joint, applying a certain amount of pressure. When applying pressure, be careful not to misalign the joint, and the pressure should be even. When heating
When the plate is heated for 15-25 minutes, it should be compressed tightly once to ensure that the joint is under sufficient pressure.
Heating vulcanization: Gradually raise the temperature of the compressed joint to 140-145 ℃, keep it constant for 45 minutes, then immediately stop heating and let it cool naturally to room temperature.
Repair: After the joint is restored to room temperature, remove the heating plate, remove the overflow residue and the rubber that is higher than the surface of the joint, and make the surface of the joint flat.
