Installation method of heat shrink tape:

One end of the heat shrink tape with a bonding wire softens the hot melt adhesive. It is installed at the one o'clock position and attached to the steel pipe along the substrate with a strip of adhesive. Then, the heat shrink tape is unfolded along the axis, and the other end of the hot melt adhesive is heated to soften it. After that, it is bonded onto the heat shrink tape according to the bonding wire and flattened with a roller.

Bake the adhesive surface of the fixed piece until soft, quickly place the adhesive surface downwards, evenly spread it on the joint in all directions, bake the inner layer of adhesive surface to make it firmly bonded to the substrate surface, and compact it with a roller.

Shrinkage and tempering

Heat evenly along the circumference from the middle position, causing the middle part to shrink first, and then heat evenly on both sides, gradually heating from the bottom to the top of the tube to make the heat shrink band shrink evenly.

After the heat shrink band has fully shrunk, uniformly temper the entire heat shrink band to maintain its surface temperature atBetween 120-140 ℃ for about 3-5 minutes, use the finger pressure method to check the melting of the inner layer of hot melt adhesive, ensuring that the inner layer of adhesive is fully melted.
