What is the factor of heat shrinkage time of heat shrinkable sleeve?

Time:2019/9/25 posted:

What are the factors related to the heat shrinkage time of the heat shrinkable sleeve?

The first point we think of should be the heating tool. The boiling time and the hot air gun obviously use the heat gun heat shrinkable tube to heat the shrinking time faster, so choosing the appropriate heat shrinkable tube heating tool is the heat shrinkable tube heat shrinking time. One of the important reasons is that heat-shrinkable tube heating tools or common heating methods include lighters, flame guns, ovens, boiled water, hot air guns, etc.

Secondly, it depends on the size of the heat-shrinkable tube. The size of the heat-shrinkable tube includes the thickness of the heat-shrinkable tube, the size of the heat-shrinkable tube, and the length of the heat-shrinkable tube. Obviously, the smaller the heat-shrinkable tube, the faster the shrinkage;

 Then the important factor affecting the heat shrinkage time of the heat shrinkable sleeve is the material itself composed of the heat shrinkable tube. Compared with PVDF and PTFE heat-shrinkable tubes, the heat-shrinkable tubes made of PVC and PE have a shorter heat shrinkage time under the same shrinkage mode. For heat-shrink tubing that requires two or three hundred temperatures to shrink, the shrinkage time is relatively slow.

In the case where the heat shrinkable sleeve size and the heating tool are the same, the heat shrinkage time of the heat shrinkable tube is affected by the heating method and the heat shrinking technique.


热缩套管热缩时间受什么因素影响

热缩套管的热收缩时间跟哪些因素有关?

第一点我们想到的应该是加热工具,水煮跟热风枪显然使用热风枪热缩管的热缩时间要更快一些,所以选择合适的热缩管加热工具是影响热缩管热缩时间的重要原因之一,热缩管加热工具或常见的加热方式有打火机,火焰枪,烘箱、水煮、热风枪等等;

其次要取决于热缩管的大小,热缩管的大小包括热缩管壁厚大小,热缩管尺寸大小,热缩管的长短大小,很显然,热缩管越小收缩越快;

接着热缩套管热缩时间影响的重要因素是热缩管组成的材质本身。PVC、PE材质的热缩管跟PVDF、PTFE材质的热缩管相比,同等收缩方式下前者的热缩时间要短。对于需要两三百温度才能收缩的热缩管,收缩时间相对较慢。

在热缩套管规格大小,加热工具等物理因素都一样的情况下,热缩管的加热收缩时间则受加热方法及热缩技巧的影响。
