The following electric heating chip manufacturers introduce the characteristics of the original silicon nitride heating element
The research of special ceramic heating element for silicon nitride heating element, through formula improvement, process optimization, and improvement of sintering process, a new type of silicon nitride ceramic heating element is prepared. Silicon nitride heating element mainly has the following characteristics:
1, The silicon nitride heating element is small in size, light in weight, and high in power density. The power density is >100W/cm2, which is much higher than the 2-8 W/cm2 of ordinary metal heating elements and the 20-80 W/cm2 of ordinary silicon nitride ceramic heating elements.
2, Through the improvement of the molding and sintering process, a silicon nitride ceramic heating element with a complex shape and an arbitrary temperature distribution can be prepared, such as a cylindrical shape. Compared with the traditional flake ceramic heating element, it has higher thermal efficiency and thermal shock resistance, and the service life of the product is greatly increased;
3. Excellent thermal characteristics. The heating efficiency is greater than 98%, and it can reach a high temperature of 800-1000°C within a few seconds. It can directly heat water, gas, kerosene, metal and other media without noise and pollution.
4. The silicon nitride heating element has high reliability.
A, High insulation performance, leakage current during operation <0.1mA, much less than 2mA of the new national standard, leakage current after breaking <7mA, no breakdown phenomenon at 2500V for one minute at room temperature;
B, Excellent mechanical properties, high compressive and flexural strength, high hardness;
C, The resistance wire will not be oxidized, and there will be less disconnection and aging;
D, Excellent corrosion resistance, can be used in harsh environments, such as molten metal, chemical corrosive liquid, etc.;
E, After a specific test, the life of the heating element>10,000h
The above is the relevant content introduced by the silicone electric heating film, I hope you like it.
