Do you know the precautions when heat shrinking the heat shrinkable tube? The editor of busbar heat shrink tubing Manufacturers china will take you to a brief introduction.
1. Before sealing, be sure to understand the applicable inner diameter and shrinking inner diameter of the casing. The shrinking inner diameter should be smaller than the outer diameter of the cable sheath, and the containing inner diameter should be larger than the outer diameter of the joint after wrapping.
2. Select the length of the heat shrinkable tube, taking into account the longitudinal shrinkage of 10-20% after being heated.
3. The inner wall of the heat shrinkable tube is generally coated with a layer of hot melt adhesive, but some are not coated, and it needs to be temporarily coated on the nozzle and sheath during use. If there is too little glue on the original tube wall, you can add some glue when using it, but it should be applied evenly, not too much. In addition, the hot-melt adhesive temporarily applied and the hot-melt adhesive of the original tube wall should be of the same adhesive, and the two cannot be mixed to avoid chemical changes. At the same time, it should be noted that according to the different use environments, three types of hot melt adhesives, such as ordinary type, moist heat type and alpine type, are prepared for use. If the temperature is lower than -5℃, it should be preheated and insulated before use.
4. It should be noted that the hot melt adhesive has a strong dry connection to the polyethylene sheath, while the adhesion to the polyethylene sheath is poor.
The above is a brief introduction to the relevant knowledge about the precautions for heat shrinking of heat shrink tubing from the editor of busbar heat shrink tubing Manufacturers china.
