How to identify the quality and service life of the heating wire ?
The life of the heating wire is related to the use time of the overall product , and it is also the most concerned issue of the business , but the vast majority of small manufacturers , do not understand the heating products , think that the low price is not necessarily bad quality , leading to the quality and brand crisis of the final listed products ( through the small series of Shenzhen XingGuang Electric Heating Products Co., LTD . ) Finally, the following points can be determined to determine the quality of the heating wire.
1. Product temperature resistance, the market common heating wire is generally divided into silicone heating wire, PVC heating wire, Teflon plus heating wire, to say temperature resistance, it is certainly the first choice for Teflon, but the expensive price makes buyers difficult to bear, PVC material is famous for Non-High Temperature Resistance, when the temperature is a little higher, it will cause the skin to melt .
The problem is that many manufacturers use recycled materials for production , which leads to materials that are not high temperature resistant more easily melt , so PVC is absolutely 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, the price is cheap, can not use recycled materials for production .
I recommend be careful to use of . But the choice is in the hands of the customer , for those who only look at the price of the Lord, I am not opposed to their use of PVC .
2. Bending performance that “ You Get What You Pay For” , a good products can not be separated from good materials , the selection of heating wire is the key to the core of life, although the market common heating wire heating conductor materials are also nickel-chromium, Constantan, copper-nickel alloy, etc., but the material is ultimately different , any industry products have good and bad , according to UL standards . Only the bending test of more than 25,000 times of the standard wire , in line with UL production technical standards.
Of course, nine out of ten manufacture company are not up to the standard , generally after 7000 bending tests , there will be a break in the heating wire .
Of course, editor Me live to watch the test of the “XingGuang’s Brand” heating wire bending standard has exceeded 70,000 times, this is a technical secret , “XingGuang Manufacturers” refused to disclose .
3. Appearance problem, OK's Standard of heating wire appearance should be smooth and bright , now many buyers buy products , if placed at home for a period of time will find that there is a layer of white hair above the insulation layer of heating wire, through the “XingGuang Company Heating Wire Manufacturers” to learn that the original behavior of stealing materials , manufacturers in order to reduce processes, reduce costs .
Often the most critical and most troublesome process is saved, although it does not affect the use, but after all, the psychology of spending money is uncomfortable.
4. Through the above introduction , I recommend that do not bring brand crisis to your products for those few cents, and it is recommended to find manufacturers that meet UL production conditions to buy products , and do not buy products through small manufacturers or traders .
