Quartz Heating Tube

Introduction to Quartz Infrared Heating Tube
A quartz infrared heating tube is a heating device that uses high-purity quartz glass as the shell and has built-in resistance wire or other heating elements. It converts electrical energy into thermal energy and radiates heat outward in the form of infrared rays. It is widely used in industrial, commercial, and household equipment. The following is a detailed introduction to the quartz infrared heating tube:
1. Structure and working principle
Shell material: high-purity quartz glass (SiO₂), which has extremely high transparency and high temperature resistance.
Heating element: usually a high-resistance material such as nickel-chromium alloy wire or carbon fiber, which generates heat when powered on.
Reflective layer: Some quartz infrared heating tubes are coated with a reflective layer (such as gold or aluminum) inside the shell to improve the directional emission efficiency of infrared rays.
Working principle: When the current passes through the heating element, the heat generated by the resistor causes the quartz glass shell to heat up and radiate infrared rays outward. Infrared rays can directly penetrate the air, be absorbed by objects, and be converted into heat energy.
2. Main features
High efficiency and energy saving: Infrared rays can directly heat the surface of objects without transferring heat through the air, so there is little energy loss and high heating efficiency.
Quick heating: Due to the low heat capacity and good thermal conductivity of quartz glass, the quartz infrared heating tube can quickly reach the set temperature in a short time.
Long life: High-purity quartz glass has excellent chemical stability and mechanical strength and can work stably in a high-temperature environment for a long time.
Uniform heating: Through optimized design, the quartz infrared heating tube can achieve a relatively uniform heating effect and avoid local overheating.
Safe and reliable: Quartz glass has good insulation properties, and it is not easy to have safety accidents such as leakage during use.
3. Application scenarios
Industrial heating:
Plastic processing: used for molding, welding, cutting, and other processes of plastic products.
Printing industry: used for drying and curing of ink.
Textile printing and dyeing: used for drying and shaping of fabrics.
Food processing: used for baking, dehydration, and other processes of food.
Commercial applications:
Heating equipment: used for outdoor heaters, bathroom heating lamps, etc.
Catering equipment: used for food heating lamps, ovens, etc.
Health care: used for physiotherapy devices, sauna rooms, etc.
Household appliances:
Kitchen appliances, such as microwave ovens, toasters, etc.
Heaters: used for indoor heating.
