How to identify the quality of silicone heating film and its service life

作者: 上海雄雷环保科技有限公司点击: Release Date: 2019-01-11 Author: Xiong Lei Shanghai Environmental Protection Technology Co., Ltd. Views:

The life of the silicone heating sheet is related to the use time of the overall product, which is also the most concerned issue for the merchants. However, most small manufacturers do not understand the heating products. Brand crisis, through the following points can determine the quality of the heating wire.

1. Product temperature resistance. Common heating wires in the market are generally divided into silicone heating wires, PVC electric heating wires, and Teflon heating wires. If it is temperature resistant, it is definitely the first choice for Teflon, but the expensive price makes buyers It is difficult to bear. The PVC material is notoriously not resistant to high temperatures. If the temperature is a little higher, it will cause the skin to melt. The biggest problem is that many manufacturers use recycled materials to produce, which causes the materials that are not resistant to high temperatures to melt more easily. Therefore, PVC is definitely not optional. Silicone is a common high temperature resistant insulation material. The outer skin is soft and elastic. The working temperature is between minus 60 degrees and 200 degrees. It is cheap and cannot be produced with recycled materials. I recommend using it, but I choose The right is in the hands of the customers. For those who only look at the price, I have no objection to their use of PVC.

2. Bending performance, it is said that the price is the same as the price. Good products are inseparable from good materials. The selection of heating wire is the key to life. Although the common heating wire heating conductors in the market are also nickel-chromium, Constantan, copper-nickel alloy, etc., but the material is still different. Any industry product is good or bad. According to the UL standard, only the heating wire with a bending test greater than 25,000 times can meet the UL production technology standard. Of course Nine out of ten did not meet the standard. Generally, after 7,000 bending tests, the heating wire would break.

3. Appearance problems. The appearance of good quality heating wire should be smooth and bright. Now, after many buyers buy the product, if they are placed at home for a period of time, they will find that there is a layer of white hair on the heating wire insulation layer. Fever film manufacturers learned that this original stealing behavior, in order to reduce production processes and reduce costs, manufacturers often save the most critical and troublesome processes, although it does not affect the use, but after all, the psychology of spending money Uncomfortable.
