Heating sheet manufacturers talk about the manufacturing process of heating sheets
We all know the performance and use of general heating tablets, how much do you know about the more special USB heating tablets?
USB heating sheet: also known as USB heating sheet, USB heating sheet. It mainly refers to the sheet material that uses the power supply of the computer USB port to heat. If it is flexible, it is also called (USB) heating film, heating film, electric heating film, etc.
Electric heating sheets
First, the advantages of USB heating sheet:
1. The surface safety is not electrified, the insulation performance is good, there is no open flame, and the use is safe.
2. Rapid heating up, high thermal efficiency, uniform heating, up to temperature 40 °C ~ 50 °C. The temperature can be easily controlled by controlling the resistor.
3. The power density can be adjusted according to customer requirements.
4. Simple structure and long life.
5. Diversified specifications, can design and produce a variety of different shapes, thicknesses, etc. according to customer requirements.
6. The heating element is insulated from air, and the components are resistant to acid, alkali and other corrosive substances.
7. Environmental protection: does not contain lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls, polybrominated diphenyl ethers and other harmful substances, fully in line with EU environmental protection requirements.
2. Main raw materials:
1. Heating resistance: metal, silver paste, carbon paste, carbon fiber, etc.
2. Protective adhesive paper: high-temperature resistant adhesive paper.
3. Technical index editing voltage: 5V.
4. Reaching temperature: 40 °C ~ 50 °C
5. Application fields: USB mouse pad heating sheet, USB slippers heating sheet, USB glove heating sheet, etc.
Third, the manufacturing process:
1. Etching: The material is mainly metal film, and the manufacturing process is similar to that of PCB circuit board.
2. Screen printing: the materials are mainly silver paste, carbon paste, carbon fiber, etc., the production process is mainly through screen printing, so that silver paste, carbon paste, carbon fiber and other materials are printed on the substrate, and then dried, cut and processed into products.
