Nowadays, more and more people use heat shrinkable sleeves to protect products such as cables and electronic wires. They think that using heat shrinkable tubes to protect cables is not only easy to operate, but also environmentally friendly. Most of the heat shrinkable tubes are made of radiation crosslinked polyolefin with excellent physical and chemical and electrical properties. It can shrink compared to 2:1 and 3:1, and some heat shrinkable tubes can even reach 6:1 And 8:1 even higher shrinkage rates. The shrinkage temperature of the heat shrinkable tube is usually between 80 degrees centigrade -125 degrees centigrade.
As we all know, the heat shrinkable tube is very high in temperature when it is contracted. Usually, the temperature is 84. So, how do you reduce it? Usually, we use a hot-air gun contraction, because it is very easy to use tools, simply look at that name can be operated, similar to the commonly used hair dryer at home, and the hot air gun as the main tool of the heat shrinkable tube contraction, from the cost consideration is very economic.
The heating operation steps of the heat shrinkable tube using a hot air gun are as follows:
The 1. hot air gun adjusts the temperature button and presses the switch.
2. micro adjust the temperature button and heat the heat shrinkable tube.
3. moving hot air gun, and changing its angle, heating the heat shrinkable tube evenly.
After this operation, you can get a perfectly shrinkable heat shrinkable tube!
