Is the metal heating strip safe? This is a question often asked by most people who use this product. As the thin heating plate is an emerging non-standard product, not many people know about it. The following author explains that the metal heating plate is safe to use through some simple instructions:
Firstly, the heating film is designed in accordance with electrical and electrical standards. There is a certain distance between the heating wire and the connection part.
Secondly, heat insulating materials used by, whether it's PET, or polyimide or silicone rubber, mica, all have very good insulation effect, the electric strength test: 1500 v / 1 min5ma, no breakdown flashover phenomenon, insulation resistance: 5 M Ω or higher. Therefore, there is no leakage phenomenon;
Third, different environment and different temperatures use different insulating materials. When the customer orders, relevant personnel of our company will make a certain assessment according to the customer's required temperature, and then recommend appropriate electrothermal film.
Fourthly, the insulation materials used in the production of heating sheets are made through high temperature and high pressure, which ensures that there will be no exposure of heating wires within a certain temperature range. Fifth, when designing the heating plate, our company will design the power according to the temperature. The heater filament of the finished product will adjust its power according to the temperature. Meanwhile, temperature control switch can be installed, which is equivalent to double protection.
Through the above analysis, the heating plate is safe in use, and its surface heating, uniform temperature characteristics will be increasingly exposed to numerous designers and users
Silicon rubber heating plate adopts heating chip heating core technology, which can fundamentally solve the following problems:
1. The heating plate is uniformly heated, which cannot be achieved by the common heating wire. The common heating wire is artificially arranged in the silicon rubber electric heating belt.
2. The heating plate has stable power and fast temperature rise. The silicon rubber heating plate using the heating plate is characterized by fast temperature rise and high heat transfer.
3. The silicon rubber heating plate adopts metal heating plate, which can greatly increase the unit power density, up to 2W/ cm2.
The heating plate has the advantages mentioned above, but there are also some disadvantages in practical application, as follows:
1. In actual production, some of the silicon rubber heating plates are relatively long, but there are more or less limitations in the length of the heating plates;
2. The width of the heating plate determines the width of the silicon rubber heating plate. The conventional heating plate is dozens of centimeters wide, which is limited by the etching machine.
3. The heating plate is more demanding than the artificial fabric method from the beginning of design, and each process is more rigorous;
4. Using the silicon rubber heating plate of the heating plate, the unit square meter price is higher than the cost of human cloth;
