Which is better, quartz glass heating tube and PTC heating tube?
Of course, the PTC ceramic heater is better. Leak easily burst quartz tube, now basically eliminated, PTC is not comparable to other heater heater, PTC heater insulation and high safety, high heat energy conversion efficiency, but also comes with constant temperature function, not because of overheating protector failure under the condition of burning, this is no other heater, the most unsafe is the quartz tube and the heating wire heater
See if you care about the cost or the environment. PTC is several times longer than quartz, and quartz is cheaper than PTC. The infrared radiation efficiency of quartz is higher than that of PTC.
PTC is a relatively new heating material with no thermal expansion coefficient and fast heating, but the heat transfer is slower than the quartz tube under the influence of efficiency.
Good afternoon, this is to see what you are for. Quartz glass heating tube is cheap and slow heating, and because of the expansion coefficient of quartz can not be used in a larger temperature change environment, so as not to burst.
