The use of hot vulcanized adhesive must clean the surface of the conveyor belt joint, and then evenly apply a layer of vulcanized adhesive on the surface of the joint and vulcanized film. Wait for the solution to evaporate until the adhesive surface is basically dry, then attach the vulcanized film to the surface of the joint coated with vulcanized adhesive, and then close the joint for pressure and heating vulcanization.
Introduction to specific usage methods of hot vulcanized adhesive:
1. 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.
2. 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, then attach the vulcanized film to the surface of the joint coated with vulcanized adhesive, and then close the joint for pressure and heating vulcanization.
3. 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 misplace the joint, and the pressure should be even. When the heating plate is heated for 15-25 minutes, it should be pressed tightly once to ensure that the joint receives sufficient pressure.
4. Heating vulcanization: Gradually raise the temperature of the compressed joint to 140-145 ℃, hold it constant for 45 minutes, then immediately stop heating and let it cool naturally to room temperature.
5. 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.
matters needing attention
1. Hot vulcanized rubber slurry belongs to organic chemicals, and attention should be paid to environmental ventilation during storage, transportation, and use.
2. The hot vulcanized adhesive becomes thicker, and an appropriate amount of specialized diluent can be added for dilution.
3. The hot vulcanized adhesive should be stored at room temperature for 12 months under sealed conditions.
