Q:Is the quartz tube electric heater good or the warm air machine good?
The PTC ceramic heating element, has the advantages of high efficiency, safety, long service life, fast heating, high heat conversion rate, no fire (not light, heating, power supply voltage fluctuations only) minimal impact and other traditional heating elements incomparable advantages, so energy saving, durable. Potential problems: the heat generated by the PTC ceramic heating element needs to be blown out by an electric fan inside the heater, and the fan will work with a little noise. Small sounds may not be appropriate for people who are particularly sensitive to sounds.
Q:Is the light wave harmful to the body?
Light wave stove barbecue tube is composed of quartz tube or pipe into the halogen tube (i.e. light tube), can quickly generate high temperature heat, cooling faster, higher heating efficiency, and will not be scorched, so as to ensure the food color. From the cost point of view, the cost of the light pipe is only a few dollars more than the copper tube or the quartz tube, so now the use of the lightwave tube in the microwave oven technology is very common.In essence: light wave is the auxiliary function of microwave oven, only for barbecue. Without microwaves, the light wave oven is only equivalent to the ordinary oven. The light wave furnace in the market is a combination of light wave and microwave. In use, it can be operated by microwave, and can be operated by light wave alone. It can also be combined with light wave and microwave. That is to say, the light wave oven is compatible with the function of the microwave oven.
Q:Does the water heater use the quartz tube heating to have the side effect to the human body?
Harm is hate small, without any side effects!
Q:What is the working principle of the electric heater of the quartz tube? Is the heating wire made of ordinary electric stove?
It is produced by the special electronic paste at high temperature by thermal decomposition or magnetron sputtering or evaporation, etc., according to your description, it should be heated by semiconductor type electrothermal film.
Q:Quartz heating tube and carbon fiber, which saves electricity?
The transparency of the quartz tube: the transparency of the quartz tube directly affects the heating capacity of the tube. The ordinary quartz tube is made of quartz, mica and so on. The quartz tube of carbon fiber is purified and treated with hydroxyl. The hydroxyl content of the quartz tube directly influences its calorific value.
Q:Is the heating tube in the oven better quartz or stainless steel?
The quartz tube heating, usually by radiation heating objects, uniform heating, not in contact with the object to be heated, but it is difficult for local heating; and the stainless steel tube is through heat conduction heating, fast heating, is not easy to be uniform, but the local heating.
Q:Heater heating mode: oil type halogen tube heating, quartz tube heating, electric heating wire, far infrared heating, electric membrane type ceramic heating, what is the difference?
Electrothermal film electric heaterThe use of transparent high temperature electrothermal film heating material, in the world's advanced level in the process. The hot air duct structure, heat transfer enhanced convection, heat starting speed, air temperature more than 3 minutes to 100 degrees, but after the power is rapidly cooled. Because the electrothermal film heating is not oxidized, service life in 100 thousand hours, and has the advantages of small size, beautiful shape, belong to the replacement of the electric heater gens. Straw siphon heat pipe air heater this year a new electric heater, it adopts a two-phase closed thermosyphon Straw as heat source, fast heating, high thermal efficiency at work. No light, no fire, not afraid of water and steam corrosion, suitable for ordinary room and a bathroom, the price of 400 yuan.Quartz tube electric heaterThe heater is an electric heating wire, put in a quartz tube. Produce light when working, should not be used in the bedroom. This small room electric heater is suitable for 10 square meters, the retail price of 130 yuan. Because the heating wire oxidation and other reasons, has not seen.
Q:The difference between quartz tube and far infrared tube in an electric oven?
Far infrared electric heating tube to tube is based on the electric heating tube is coated with infrared coating, the heat radiation of the electric heating tube frequency into the far infrared frequency, so that the material to be heated to better absorb heat from the heating tube, far infrared heating and high thermal efficiency, energy saving.
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:Which is better, quartz glass heating tube and PTC heating tube?
Good afternoon, this is to see what you are for. Quartz glass heating tube is cheap and slow heating, and because of the expansion coefficient of quartz can not be used in a larger temperature change environment, so as not to burst.
