Mica Silicone Electric Heating Sheet
1. Manufacturing method of mica heating plate. The heating wire used in the mica electric heating plate is to first press the electric heating alloy material into a thin plate of only a few millimeters, and then use the method of corrosion or laser cutting to make it shape, and then use the adhesive method to stick the heating wire to the mica The substrate is formed by high-strength die-casting. The electric heating wire is characterized by high temperature and high power density.

2. Features of mica heating plate and comparison with Jiankun products:
1) The heating wire mica heating plate adopts the gluing process, the metal heating wire and the mica plate have different expansion coefficients after heating, and they are simply layered. Together, they will simply drop after the glue volatilizes under high temperature. The heating wire is easy to interweave. Short circuit. It is mechanical connection, no glue process, high temperature resistance, not easy to fall, and safe.
2) Because of the special gluing process of the heating wire, the glue will turn into a powder at high temperature and emit an unpleasant odor, and the odor is rich in formaldehyde. And our products are glue-free technology, tasteless and environmentally friendly, with SGS environmental protection statement.
3) The local current of the heating wire in the corner is too large, the temperature is too high (up to 500-700 degrees), simple damage and formation risk, some manufacturers have shown that the mica base material is burned out of a black hole, and even caused Risk of fire. Our products are flat heating, uniform temperature, not easy to melt.
4) Because the heating wire is linear heating, it is difficult to ensure the uniformity of heating. The surface temperature of the heating wire reaches 500 degrees. Therefore, the heating wire mica electric heating plate will burn out linear black on the surface of the mica plate after a period of time. Imprints, the effect is beautiful. If the external mica is exposed to this kind of high temperature for a long time, it can affect the service life of the mica base material.
5) The mica heating plate has a large starting current, usually 3-4 times the rated current, and it also heats up in the junction box. Therefore, the heating plate simply presents the appearance of firing and firing in the outlet box, even in the products of some supporting manufacturers. It presents the appearance of a big black hole burning at the junction box. The starting current of our products is small, usually about 0.8 times the rated current, the current is stable, and the leakage current is usually less than 0.025mA.
6) The mica electric heating element uses a series circuit design. If one point is damaged, the entire electric heater is scrapped, and our product uses a full parallel circuit design. If it shows extreme conditions, even if a hot piece is damaged, It also does not affect other hot parts operations.
The above is the relevant content introduced to you by the editor of the heating film manufacturer, I hope it will be helpful to you.
