Which is better, quartz glass heating tube or PTC heating tube?
It depends on what you're doing exactly. Both have their own strengths.
Quartz glass heating tube is cheap, the heating speed is slow, and because the expansion coefficient of quartz cannot be used in an environment with large temperature changes to avoid bursting.
PTC is a relatively new heat-generating material, has no coefficient of thermal expansion, heats up quickly, but the thermal conversion is slower than that of quartz tube due to efficiency.
So depending on whether you care about the cost or the use environment, PTC has a service life several times longer than quartz, and quartz is cheaper than PTC. Quartz is more efficient than PTC in infrared radiation. You weigh the best for yourself as needed
PTC heating element, also known as PTC heater, is composed of PTC ceramic heating element and aluminum tube. This type of PTC heating element has the advantages of small thermal resistance and high heat exchange efficiency, and is an automatic constant temperature electric heater. The main use temperature is generally less than 200 degrees, and its disadvantages are prone to local diffuse breakdown. Carbon fiber heating tube is made of carbon fiber filament or graphite carbon felt with a carbon content of more than 95 as the heating element, and its insulating shell is high temperature resistant and corrosion-resistant quartz glass. It has the characteristics of rapid heating, high electrothermal conversion efficiency, energy saving, environmental protection and health, and the use temperature is 600 degrees.
