Quartz tube heating principle
Quartz tube is used by a special process of milky quartz glass tube, with resistance materials as a heater, because the milky quartz glass can absorb almost all of the visible and near-infrared light from the radiation of the electric wire, and can be converted to far-infrared radiation. But the current industrial infrared heater basically eliminated the milky white quartz tube, because of its material is relatively brittle, so it can not form a very long milky white heater. And the milky white color has a shading effect, preventing its heat. Because of its wall temperature is high, so it is only suitable for near infrared heating.
Quartz tube technical characteristics
(1) no need for far quartz coating, spectral radiation matching absorption characteristics, long-term use of radiation performance does not degenerate, high efficiency of electric heat conversion. Energy saving of about 30% than the general heating element.
(2) High operating temperature, wide selection range. One of the ceramic cap encapsulation type, the highest temperature resistance up to 800 ℃.
(3) fast warming, small thermal inertia, high temperature resistance, corrosion resistance, good stability of thermochemical properties, long service life, high insulation strength.
(4) No pollution, is a clean heating tube, in line with the modern production of high rhythm, high quality requirements, suitable for high hygiene requirements of household appliances.
(5) Design, manufacture and installation are very convenient, economical and safe.
Quartz tube chemical properties
High temperature resistance-quartz tube
Quartz glass softening point temperature of about 1730 ℃, can be used for a long time at 1100 ℃, a short period of time the highest temperature of up to 1450 ℃,
Corrosion-resistant-quartz tube
In addition to hydrofluoric acid, quartz glass is almost no chemical reaction with other acids
The quartz glass has the ability to resist acid 30 times more than ceramics and 150 times more than stainless steel, especially the chemical stability at high temperature, which is incomparable to any other engineering materials.
Quartz tube specifications
Gauge_according to your needs, the specifications include outer diameter, wall thickness, length. Each factory has different products, so the specifications are different. Because of the electric melting furnace production, out of Lei's products can not be exactly the same diameter and wall thickness, there is a certain discrepancy.
Quartz tube prices
Quartz tube prices up and down may be relatively large, because the material of the quartz tube will be good and bad points, the caliber of the larger, better material quartz tube prices will naturally be higher. And some of this expensive quartz tube heat resistance and other aspects of performance will be better, so a penny a penny this sentence is not bad at all. However, for the purchase of quartz tube I still recommend that you buy better quality, thought if you buy some poor quality quartz tube its heating performance and heat resistance may be affected.
