Q:Electronic energy saving heater and quartz tube heating rod
A heat pump is used to transfer heat from cryogenic objects to high temperature objects through a refrigeration system. Because of the basic structure of the system, the amount of heat released to the high temperature object is always greater than that used in the process.
Q:What are the hazards of the quartz tube electric heater?
Appliances as long as the electricity will produce radiation, the radiation here refers to electromagnetic radiation, harmful to the human body.
Q:Why can quartz glass heating tubes be heated?
Not that it can be heated, but that it can be burned, and that the high temperature is not afraid of it
Q:What is quartz tube for?
Electrical insulation performance is good, quartz glass resistance value is equivalent to ten thousand times of ordinary glass, is an excellent electrical insulation material, even in high temperature also has good electrical performance. Because of its excellent physical and chemical properties, quartz glass has been widely used in many fields, such as electric light source, semiconductor, optical communication, military industry, metallurgy, building material, chemical, mechanical, electric power, environmental protection and so on. Quartz tube types can be divided into the following categories: transparent quartz tube (outer diameter 1.5mm--300mm), filter quartz tube, color quartz tube and so on.
Q:Which is better, light wave oven or induction cooker, for cooking or cooking?
Light wave ovens (microwave and microwave ovens), like microwave ovens, are suitable for heating food, thawing, and doing some types of dishes. A light wave oven can grill corn, sweet potatoes and kebabs.
Q:What's the quartz tube in the microwave oven for?
Such as transparent, is an ultraviolet tube (not in the microwave oven, used in the disinfection cabinet), used for sterilization, disinfection.
Q:The working principle of quartz glass heating tube
SH far infrared quartz heating element adopts our own production of quartz tube with electrothermal materials, so that the original with far infrared radiation characteristics: good and reliable electricity, electric materials from the infrared and visible light in 97% is blocked by the absorption of milky tube makes the temperature of tube wall high rise student silicon oxygen bond of molecular vibration far infrared radiation 97%, so that the visible light and near infrared light can be turned into the far infrared radiation. And effectively convert electric energy into far infrared ray.
Q:Quartz tube heater principle
Far infrared heating tube is used by the opal quartz glass tube, with special processing of resistance alloy material as a heating element, the opal quartz glass can be absorbed into the electric wire from radiation almost all of the visible light and near infrared light, and can make the far infrared radiation. But the current industrial infrared heating tube basically eliminates the milky white quartz tube, because of its relatively brittle material, it can not form a very long white heating tube. The milky white has an anti - light effect that stops its heat. Because of its high wall temperature, it is only suitable for near infrared heating.
Q:The difference between a quartz tube and a halogen tube
Halogen tubes have their main properties:1. The electric performance is stable, the electric heating power is stable, the heating rate is fast, and the electric heating conversion rate is as high as 70%;2, high thermal efficiency, heating non oxidation, service life of up to 3000 hours or more, safe and reliable;3, the work of the light emitted by visible and near infrared light based, more than 84% concentrated in 0.75 m ~ 3.5 mu m region. Fully comply with the basic environmental test procedures for GB/T241993 electrical and electronic products, as well as the general safety requirements for GB4706.1-19921 household and similar electrical appliances.
Q:What can be cut off by a quartz tube?
If it is not very thick, with the new triangular file, with a hard edge pressure pull in point, will draw a crack. Wrapped here with cotton cloth, hands clenched, two fingers close the top of the scratch back, simply landing, with a break, bang, completed.
