It can withstand 327 ℃ high temperature.
The crystallinity of raw meal belt is 90~95%, and the melting temperature is 327~342 ℃.
The chemical name of the raw material belt is polytetrafluoroethylene. The relative molecular weight of polytetrafluoroethylene is relatively large, ranging from hundreds of thousands for low ones to tens of millions for high ones, generally millions (polymerization degree is 104, while polyethylene is only 103).
1. When using the raw material belt, it should be noted that using it in a normal way can improve the effect, and if it is used incorrectly, it will reduce the functionality.
2. Generally, the raw material belt needs to be wound along the thread direction. It is not allowed to wrap all threads with the raw material belt. Once the raw material belt enters the pipe, the sealing performance will be reduced. It is a better way to start winding from the second silk tooth, leaving the front silk tooth.
3. Attention shall be paid during winding to ensure that the raw material belt is not pulled off, so as to make the raw material belt more firm and tight and have better sealing performance in later use.
4. As for the question of how many circles to wrap the raw material belt, it needs to be determined according to the specific experience of the decoration master. Generally, the thickness of the second half of the raw material belt wrapped out is larger, that is, it is thinner in the front and thicker in the back, which can ensure that the screws become more and more tight in the process of rotation and improve the sealing performance.
5. After the raw material belt is wound, do not withdraw the thread when screwing in the screw, otherwise it needs to be rewound and tightened.
