1) Heating film is an emerging electric heating element in recent years, which absorbs the characteristics of PTC and conductive coatings, and is mainly used for indoor heating and environmental temperature maintenance.
2), fast thermal conduction, long service life (about 30-50 years).
3) The power conversion efficiency is as high as 90%, and the heat energy loss is small.
shortcoming
1) The heating rate is slow. 2) The heating temperature cannot reach a high value for the time being.
3) The heat dissipation speed is fast after power failure. Current situation of heating film industry
1. There is a potential development bottleneck of name confusion, lack of standards and disorderly competition. The slogans are varied, with many manufacturers claiming that their products are "first", "unique" and "best". This reflects the disorderly and chaotic development of the heating film industry.
2. Most domestic heating film manufacturers do not have the conditions for floor heating system design and construction, and do not cooperate with relevant enterprises to discuss the construction process and safety protection measures suitable for their own products, but are eager to push the product to the floor heating project, many enterprise leaders, even the heating film leakage current is equivalent to leakage, and very ridiculously claim that their insulation is very good, no leakage current. (No leakage does not mean no leakage current)
3. The unfair competition in the heating film industry is also manifested in the commitment to exceed its own capabilities, such as service life and cost.
