Quartz glass tube is a special industrial technical glass made of silica, which is a very good basic material. Quartz glass has a series of excellent physical and chemical properties. Used in electric fire barrels, electric roasting stoves, electric heaters, and play a role in heating. There are many quartz tube manufacturers on the market now, and the quality of the products varies, and consumers are always hesitant when choosing. Today I recommend a few good quartz tube manufacturers for everyone, I hope to help you buy.
Quartz tube heating principle
The quartz tube is a milky quartz glass tube processed by a special process, and is equipped with a resistance composite material as a heater. Because the milky quartz glass can absorb almost all visible light and near infrared light radiated from the heating wire, and can be converted into Far infrared radiation. However, the current industrial infrared heating tube basically eliminates the milky white quartz tube. Because its material is relatively brittle, it cannot form a very long milky white heating tube. And milky white has a shading effect, preventing its heat. Because of its high wall temperature, it is only suitable for near infrared heating.
Technical characteristics of quartz tube
(1) No need for far-quartz coating, good spectral radiation matching and absorption characteristics, long-term use of radiation performance does not deteriorate, high electro-thermal conversion efficiency. It is about 30% more energy-saving than general heating elements.
(2) High operating temperature and wide selection range. Among them, the ceramic cap package type has a maximum temperature resistance of 800 ℃.
(3) Fast temperature rise, small thermal inertia, high temperature resistance, corrosion resistance, good thermochemical stability, long service life, and high insulation strength.
(4) No pollution, it is a clean heating tube, which meets the requirements of modern production with high rhythm and high quality, and is suitable for household appliances with high hygiene requirements.
(5) Design, manufacture and installation are very convenient, economic and safe.
Quartz tube chemical properties
High temperature resistant · Quartz tube
The softening point temperature of quartz glass is about 1730 ℃, which can be used for a long time at 1100 ℃, and the maximum use temperature can reach 1450 ℃ in a short time.
Corrosion resistance · Quartz tube
Except for hydrofluoric acid, quartz glass hardly chemically reacts with other acids. Its acid resistance is 30 times that of ceramics and 150 times that of stainless steel. Especially its chemical stability at high temperatures is beyond any other engineering materials Comparable.
Quartz tube specifications
The gauge depends on your needs, and the specifications include outer diameter, wall thickness, and length. Each factory has different products, so the specifications are different. Because it is produced by an electric furnace, the outer diameter and wall thickness of the Lei product cannot be exactly the same, and there is a certain difference.
Quartz tube price
The price of the quartz tube may fluctuate up and down, because the material of the quartz tube will be good or bad. The price of the quartz tube with a large diameter and better material will naturally be higher. And this kind of expensive quartz tube has better performance in all aspects, such as heat resistance, so the price of one cent for every price is good. However, for the purchase of quartz tube editors, it is recommended that you buy better quality, thinking that if you buy some inferior quartz tube, its heating performance and heat resistance may be affected.
