First. Equipment: small pressure equipment with automatic temperature control, timing and multi-specification tubular cavity.
Second. Rubber material: It is the same as the wire material of the supplemented wire, and the rubber content is higher than that of the material to be supplemented, and the vulcanization system is slightly stronger.
Third. Operation method:
1. Set the temperature and time according to the vulcanization system of the rubber compound;
2. Use the rubber ink thinner to wash the repaired part, especially the joint should be fully treated;
3. Cut an appropriate amount of repair rubber according to the size of the gap, pay attention not to be too much or too little;
4. Plug the cut rubber into the gap, pay attention that the rubber should not be higher than the circumference of the wire;
5. Wrap it with high temperature resistant PP tape. Put it into a tubular mold cavity slightly smaller than the wire diameter, lock the upper and lower molds, and make the supplemented position have a certain pressure. Note that the cavity diameter is slightly smaller than the wire diameter by 0.1~0.2mm;
6. When the vulcanization time is up, take out the product. If a small amount of rubber material overflows, use a sharp blade to trim it off and wipe it off with a thinner.
Fourth. The verification method:
Press an appropriate amount of air into the supplemented wire and place it in the water, and you can judge whether it is good or bad when you see whether there is air leakage.
