1, partial defect repair method
Breakdown points, holes, pits and other repair methods
The knife is used to trim the defects, and a plastic block with a uniform size and a slope of 45° is cut and placed on the repair area, fixed with a pliers or a screwdriver, and then continuously welded with a hot air speed welding torch, and compacted and pressed with a copper sheet. Tight, flattened. When welding plastic, pay attention to the hot air temperature of the welding torch not too high, so as not to repair the plastic scorch at the repair site. The repaired defect is tested by the spark machine without breakdown.
Use a knife to cut the slope of the plastic layer at a 45-degree angle, and remove the shape, color, and thickness of the plastic block or strip. After fixing it with a pliers or a screwdriver, use a hot air speed welding gun to connect it. Then use a copper sheet to compact it. , Compaction, flattening, and finally spark test, no breakdown is qualified.
The plastic defect is scraped with a knife, the recessed part is filled with the same plastic strip under the action of a hot wind plastic welding gun, then flattened, pressed and compacted with a copper piece at the defect repairing place, and the spark test is performed without breakdown. Qualified.
2. Repair method of big joint
1) Repair of general large joints: cut both sides of the broken plastic with a knife on the plastic layer along the circumference
45 ° angle slope, take a clean, uniform color and thickness, the length and diameter of the plastic tube consistent with the broken plastic tube, on the side of the tube along the axis cut to each other with an angle of 45 ° open sets of broken plastic At the same time, the thin copper wire is used to equip with equal distance, and then the same plastic strip is welded under the hot wind plastic welding torch, and the welding is good, and the copper sheet is used for compaction, pressing and flattening. After the spark machine test does not breakdown is qualified.
2) Repair of large joints in the production process: In the production process, due to other reasons, it is temporarily parked and the sheath is disconnected. The method is to cut the plastic jacket into a 45-degree-circular slope shape, withdraw it to the machine head, extend it into the mouth of the mold core for 30mm, and then run the glue. After the glue is run, the crew members cooperate with each other and drive. When the plastic layer is connected by hand, then plastic repair.
3) The quality of the cable jacket is longer than the length of one end of the cable. The other jacket is well-sealed and the length of the cable is fixed. It can also be used to repair large connectors in the production process. Only after removing the end cap with quality defects, select a larger die on the extruder. Press the process to squeeze the sheath on one end first. Gradually increase the traction speed at the large joint to gradually make the sheath at the interface gradually. Thinned and covered on the original sheath cut into the slope shape, after the next machine and plastic repair.
