We all know the performance and use of general heat-generating film. How much do you know about the more special usb heat-generating film?
The Chinese name usb heating film is also called usb heating film. Advantages: The surface is safe and non-charged, and the insulation performance is good. The base material is environmentally friendly.
Usb heating film: also called usb heating film, usb electric heating film. Mainly refers to the sheet material heated by the power of the computer's USB port. If it is flexible, it is also called (usb) heating film, heating film, electric heating film and so on.
1. Advantages of USB heating film:
1. The surface is safe and non-charged, with good insulation performance, no open flame, and safe to use.
2. Rapid heating, high thermal efficiency, uniform heating, up to a temperature of 40℃~50℃. The temperature can be easily controlled by controlling the resistance.
3. The power density can be adjusted according to customer requirements.
4. Simple structure and long life.
5. The specifications are diversified, and various shapes and thicknesses can be designed and produced according to customer requirements.
6. The heating element is insulated from the air, and the components are resistant to acid, alkali and other corrosive substances.
7. Environmental protection: It does not contain harmful substances such as lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls, polybrominated diphenyl ethers, etc., and fully complies with EU environmental protection requirements.
2. Main raw materials:
1. Heating resistance: metal, silver paste, carbon paste, carbon fiber, etc.
2. Protective tape: high temperature resistant tape.
3. The voltage used for editing technical indicators: 5v.
4. Reachable temperature: 40℃~50℃
5. Application fields: USB mouse pad heating film, USB slippers heating film, usb glove heating film, etc.
Three, manufacturing process:
1. Etching: The material is mainly metal film, and the manufacturing process is similar to that of PCB circuit boards.
2. Screen printing: The materials are mainly silver paste, carbon paste, carbon fiber, etc. The production process is mainly through screen printing, so that the silver paste, carbon paste, carbon fiber and other materials are printed on the substrate, then dried and cut into products.
