Insulation electrothermal coating technology and equipment
1,Insulation electrothermal coating step：
(1),First, spray a layer of 0.1-0.3 mm insulation ceramic coating on aluminum sheet.
(2), The ceramic insulation coatings is sprayed a layer of 0.05-0.10 mm Ni Cr strip or Fe Cr Al coating. The two ends of the coating are equipped with electrodes, which can be heated by electricity.
(3), then cover a layer of 0.1-0.3 mm insulation ceramic coating, to achieve insulation requirements
2,Coating parameters
*Electric heating power 0-5 kw
*Heating temperature 0-300 degrees, the temperature is adjustable
*The insulation resistance value is more than 10 megohm
*Insulation voltage is above 2200V
*Coating bonding strength is above 50Mpa, the coating does not fall off, can not peeling, no swelling.
*For safe low voltage, AC and DC power, no radiation
3,Application scope of insulation electric heating coating
* Anti fog mirror for automobile
* Outdoor snow melting equipment
* Medical electric heating sterilizing apparatus
* Food heating and drying
* Anti freezing electric heating device for automobile water tank
