Q:Quartz heating tube and carbon fiber, which saves electricity?
Service life comparison: ordinary quartz heating tube has an operating life of less than an hour. The service life of carbon fiber heating tube is: hour.
Q:Can quartz tubes be used in a vacuum tube furnace of 1300 degrees?
It's better to have a better qualityGenerally fused quartz tube is the use of temperature in 1100-1200 degrees, there is a bad estimate, 1050 on the crackOK, quartz tube can be used 1300 degrees in a short time,If the money is not bad, then the gas smelting quartz, then 1300 no problemIf more than this temperature, usually choose other high temperature materials
Q:Can the electric heating wire in the quartz tube be replaced by an electric tungsten wire?
Divided into civilian and industrial use.For civilian use, mainly for heaters and light wave furnaces.For those who need almost industrial heating industry: printing and dyeing, footwear, coating, food, electronics, medicine, textile, wood, paper, plastics, automotive, furniture, metal, heat treatment, packaging machinery and so on.The far infrared heating tube has the characteristics of high density, high heat efficiency and low energy consumption. Using this tube as a heater, heating element oven etc heating equipment than ordinary infrared heating can greatly improve work efficiency, shorten the heating cycle, saving equipment space, save energy, reduce the production cost.
Q:Which is better, light wave oven or induction cooker, for cooking or cooking?
There is no comparability, each function is different.The electromagnetic oven is suitable for cooking, boiling water, steaming, cooking, eating Steamed Buns Steamed Rice Hot pot etc..
Q:Excuse me, what is the raw material of quartz tube drawing, can say the best raw materials in quartz tube
The ore is mined, selected, broken, cleaned, treated (purified) - made into powder, and can be used to produce quartz for various processes.
Q:What are the differences between carbon tubes and halogen tubes?
Quartz heating tube: halogen tube (halogen quartz heating tube)Carbon tube (carbon quartz heating tube). The quartz tube on the outer surface of the quartz heating tube has a transparent quartz tube (transparent color), a milky white quartz tube (milky white opaque), and a ruby quartz tube (wine red translucent).Life: halogen tube is normal, more than 3000 hours life, there are more than 5000 hours.
Q:The working principle of quartz glass heating tube
SH far infrared quartz heating element is a milky white quartz tube infrared radiation source, no coating, no pollution, no harmful radiation, excellent chemical stability, high temperature resistance, no deformation shapes, long-term use, good thermal stability, can choose the heating temperature. Long term use, radiation performance is not degeneration. The utility model has the advantages of long service life, reasonable structure, minimal thermal inertia and convenient operation. SH far infrared quartz heater is the only best infrared radiation element in china.
Q:Disinfection cabinet light wave or quartz tube good?
Personally feel that the quartz tube is good, high temperature, but brightness is not very large, will not be very dazzling said!
Q:What are the defect of the ceramic heater and quartz tube heating?
PTC heater is almost perfect, it has no other heater, thermal energy conversion rate is high, the insulation degree of Grade A, long service life, the most important also comes with constant temperature function, not dry or burned because of overheating protection device failure, PTC heater will automatically control the temperature in a certain range, do not let the temperature rising.
Q:The difference between a quartz tube and a halogen tube
The difference between a quartz tube and a halogen tube:Quartz tube is a kind of special industrial technology glass made of silicon dioxide. It is a very good basic material. Quartz glass has a series of excellent physical and chemical properties for electric fire bucket, electric heating stove, electric heater, heating up.
We are established by a team of senior engineers experienced in the processing of quartz glass, artificial crystal and mono-crystalline silicon products. We have rich technical force and utilizes first-class equipment. Having implemented a digital management system that extends to all production processes, we use inspection instruments that lead the domestic quartz glass industry. We have obtained the certification of ISO 9001:2000 and ISO 14001:2004
