Why Carbon Fiber Heaters Fail with Quartz Tube Damage?

Some users have expressed concerns when using инфрацрвени грејни елементи од јаглеродни влакна: “Why does the heating element cease to function after the outer quartz tube is damaged?” Let’s explore this issue today.

Carbon Fiber Vacuum Heating Tubes
The development of resistive heating elements has evolved from traditional metal resistance wires to alloy resistance wires, and now to carbon fiber heating wires. Typical metal resistance wires include tungsten wire infrared heating tubes, and for alloy wires, there are iron-nickel alloy heating tubes. The thermal stability of these heating wires varies, which dictates their suitable operating environments. Metal resistance wires and carbon fiber heating wires, due to their inferior temperature performance when heated, require a vacuum or an inert gas environment to function effectively for extended periods. On the other hand, iron-nickel alloy wires and similar alloys exhibit higher thermal stability, allowing them to be heated directly in open air.

This explanation clarifies why инфрацрвени грејни елементи од јаглеродни влакна cannot be used if they are exposed to air or are physically damaged. The quartz tube surrounding the carbon fiber wires plays a crucial role in protecting these wires from oxidation and environmental contaminants. Additionally, it helps maintain a sealed, controlled atmosphere that is essential for the efficient operation of the heating elements. When the quartz tube is compromised, either through cracks or breaks, it fails to protect the delicate carbon fibers from oxidizing and becoming physically damaged, ultimately leading to the failure of the heating element.

It’s essential to handle carbon fiber heater elements with care during installation and use, avoiding any rough treatment that might damage the quartz tube and affect the element’s functionality.
