In recent years, the heat of electric blankets has been hotter in demand . Especially in developed countries with relatively high living standards, such as the United States, Europe, Japan, South Korea and other countries, in fact, the domestic demand is also a lot, but the level of consumption is limited, manufacturers are subject to cost pressure, often take the cheap route, the outcome can be imagined, then why there has the question about electric blankets only accept the PTC or NTC heating wire ?
In fact, electric blankets in the country before 1990, there are manufacturers in the production on domestic , but at that time by technical limitations, the use of relatively cheap heating wire , simple and rough, but also easy to fire , the function is relatively simple , the control principle is simple 1,2,3 gear voltage reduction principle, responsible for a little manufacturers , at most is to add a protector , can not be washed .
With the development of the reform , the southern enterprises slowly opened the foreign market , the technical standards of the products, of course , also have to be produced in accordance with foreign standards , such as UL,CUL,ROHS, etc. , the reference basis is also copied to the domestic by other countries , the production technology has been updated for several generations , from the previous simple and rough , to today's intelligent control , It is now the age of NTC technology , which explains the problem described in the title .
The advantage of PTC-NTC heating wire is that the intelligent heating wire integrated with heating and control , data matching is difficult, completely eliminated the traditional protective device, and the form of temperature probe production of electric blankets , feel better, simple installation, efficient production, safer, more intelligent , more high-end, export products must be implemented standards , and is also a prerequisite for foreign customers !
