Description: I
T is made of the surface resistance to high temperature insulation treatment of iron chrome aluminum heating element.
Feature:
When used in the 1000 centigrade, there is almost no volatile matter. Being used between 1000 centigrade and 1250 centigrade, the voltatile is less and transparent. It has a long service life used in high temperature. Thermal efficiency increased by more than 20%.
Usage:
It is widely used in all kinds of electric heater and heating equipment.
Especially suitable for making such as high temperature far infrared radiator, electric oven devices such as the heating element.
The main performance
1. Can be arbitrary direction installed and used.
2. There is no need of protective atmosphere or vacuum protection, assembly is convenient, low cost, use security.
3. Heating up fast, high thermal efficiency, temperature uniformity.
4. Service life: 10000--500000 hours.
