Ceramic heating tube: A brief introduction of ceramic heating tube
The ceramic heating tube is made of ceramic matrix and electric heating wire, which has the advantages of high electrothermal conversion efficiency, fast heating speed, small thermal inertia, high temperature resistance, corrosion resistance, good thermochemical stability, long service life, high insulation strength, and no pollution.
Ceramic heating tube features
1. Good thermal efficiency, uniform heat:
2. High temperature resistance, corrosion resistance;
3. Good safety performance
4. long lasting.
5. The product can be applied to the heating of various electric boilers in enterprises.
Composition of ceramic heating tube
1. Matrix: mainly composed of ceramic composite materials with good thermal shock resistance;
2. Calorific value: Nickel-chromium alloy wire is used;
Ceramic heating tube parameters
1. Radiation characteristics: The monochromatic emissivity of elements is 0.9, and the normal total emissivity is greater than 0.83.
2. Thermal response working time: from room temperature to the surface of a radiant panel to keep the temperature at a constant value for no more than 20 minutes.
3. Cold and hot alternating resistance: After five times of alternating hot and cold tests, there is no peeling or cracking.
4. Inhomogeneity of radiation surface temperature: 15%≤
5. Power error: rated working voltage ≤5%
6. Cold insulation resistance: 500V megger > > 2mω
7. Thermal insulating material resistance: 500V megohmmeter > 0.5mΩ
