First, equipment: Small-scale pressure equipment with automatic temperature control, timing and multi-size tubular cavity.
Second, the rubber material: consistent with the wire of the wire, and the glue content is higher than the material being filled, the vulcanization system is slightly stronger.
Third, the operation method:
1. Set the temperature and time according to the vulcanization system of the rubber material. 2. Use a rubber ink thinner to wash the repaired area, especially the joint area.
3, according to the size of the gap to cut the amount of repair rubber, pay attention to not too much or too little,
4. Put the cut plastic material in the gap, and pay attention to that the rubber material should not be higher than the circumferential surface of the wire.
5, wrapped with high temperature PP tape. Place it in a tubular mold cavity that is slightly smaller than the wire diameter, and lock the upper and lower molds so that there is a certain pressure in the fill position. Note that the cavity diameter is slightly smaller than the wire diameter by 0.1~0.2mm.
6, until the vulcanization time is reached, remove the product, if there is a small amount of rubber spills, use a sharp blade to complete, and dilute with a diluent.
Fourth, verification method:
Press the appropriate amount of air into the filled wire and place it in water.
