The quartz is in charge of the heater to heat silks and put a kind of electric heater in the quartz is in charge of. Because the quartz is in charge of having function of alternative far infrared radiation , compare with other heating components , it is far infrared coating for it not to need, spectrum radiation is it absorb characteristic to be fine to match , long run radiation performance is it to retreat, it is with high efficiency that the electric heat is changed, than generally heat about 30% of component energy-conservation; Intensify fast , hot little inertia, able to bear high temperature, corrosion-resistant, hot chemical property stability kind, having long performance life, dielectric strength is high , pollution-free; The hot response time is short, especially suitable for the heating occasion closed down frequently. Meanwhile, it is very convenient for it to design , make , install, an economic security
