Heating principle of quartz tube
The quartz tube is made of ivory glass tube with special technology, and is equipped with resistance material as heater. Because the opalescent glass can absorb almost all visible light and near infrared light radiated by electric heating wires, it can be converted into far infrared radiation. However, at present, the ivory quartz tube is basically eliminated from industrial infrared heating tubes, because its material is brittle, and it is impossible to form a long ivory heating tube. And milky white has a shading effect to prevent it from heating. Because of its high wall temperature, it is only suitable for near infrared heating.
Technical characteristics of quartz tube
(1) does not need a long-time coating, and has good spectral radiation matching absorption characteristics. After long-term use, the radiation performance does not deteriorate, and the electrothermal conversion efficiency is high. Energy saving is about 30% compared with general heating elements.
(2) High working temperature and wide selection range. Among them, the temperature resistance of ceramic cap packaging type can reach up to 800℃.
(3) rapid temperature rise, small thermal inertia, high temperature resistance, corrosion resistance, good thermochemical stability, long service life and high insulation strength.
(4) pollution-free, it is a clean heating pipe, which meets the requirements of high rhythm and high quality in modern production and is suitable for household appliances with high hygiene requirements.
(5) The design, manufacture and installation are very convenient, economical and safe.
Chemical properties of quartz tube
High temperature quartz tube
The softening point of the timely glass is about 1730℃, and it can be used at 1 100℃ for a long time, and the highest service temperature can reach 1450℃ in a short time.
Corrosion resistant quartz tube
Except hydrofluoric acid, the timely glass hardly reacts with other acids, and its acid resistance is 30 times that of ceramics, and the chemical stability of stainless steel 150 times, especially at high temperature, is incomparable to any other engineering materials.
Quartz tube specification
Specifications _ According to your requirements, specifications include outer diameter, wall thickness and length. The products of each factory are different, so the specifications are different. Because it is produced by electric melting furnace, the outer diameter and wall thickness of the product can not be exactly the same, and there is a certain discrepancy.
Quartz tube price
The price of quartz tube may fluctuate greatly, because the material of quartz tube will be good or bad, and the price of quartz tube with large diameter and good material will naturally be higher. Moreover, the performance of this expensive quartz tube in heat resistance and other aspects will be better, and the value for money will be good. However, I suggest you buy quartz tubes with better quality, thinking that if you buy some inferior quartz tubes, their heating performance and heat resistance may be affected.
