During the whole process of application, the drag chain will crack due to the release of ground stress, and the paint layer on the surface will also crack, which will seriously damage the appearance of the keel chain, and even more seriously, the actual application effect of the cable drag chain. If iron putty powder is used to make up for welding defects such as air holes and sand holes, because the adhesive compressive strength of putty powder is extremely low, it will loosen and fall off in the subsequent work due to vibration, which is often the key reason why several paint layers fall off in less than two years after customers purchase CNC lathes, The surface quality of CNC lathe is seriously damaged.

The protective film is a common small spare part in the cable drag chain. It plays a key role in the tidiness of the cables and bronchi in the silent drag chain, but the small volume has a large main purpose. Now let's talk about the selection of protective film. What should we pay attention to in the selection?

1. Key types of shields

The key to the type of protective sheet is that the materials are different. In the same situation, the protective sheet of cable drag chain has two materials: plastic protective sheet and polyester product, which should be more common; The second is made of metal products. The basic one is metal aluminum, which is also specially made.

2. Under which condition shall protective sheet be applied

Whether the protective sheet is used in the cable drag chain depends on the essential placement. When there are many essential wires, cables and bronchi, in order to better avoid coiling at work, it is also necessary to apply the protective sheet when it is messy and endangers the external beauty, and separate them according to the actual effect to be achieved.

3. Application standard of protective sheet

The cable drag chain can apply polyester protective film in the same application natural environment, except under some high temperature and ultra-low temperature standards, when the polyester protective film cannot bear, it can be applied. The polyester protective film is easy to manufacture, low in cost, and has less friction on the cable for maintenance, so its application scope is wider. However, the aluminum protective sheet is relatively inconvenient to manufacture and the cost is relatively high. If the surface of the cable drag chain is not smooth enough to manufacture, it will continue to damage the items to be maintained.
