Q:Is the heating tube in the oven better quartz or stainless steel?
The heating elements used in electric ovens can be broadly divided into three categories: one is an electric oven using a far infrared tube and a quartz heating tube, and the other is the lower grade of all electric ovens. However, the basic function is to achieve the electricity, just baked speed will slow down a bit.
Q:Halogen tube, quartz tube, carbon fiber, which is good?
Carbon fiber is good.The carbon fiber electric heater is a new type of electric heater designed and made of high and new material carbon fiber heating wire as heating element. With thermostat, remote control, new carbon fiber heater, new carbon fiber heater with heating and heating function, as well as radiation of far infrared, green, high efficiency, energy saving, safe and convenient.
Q:Why can quartz glass heating tubes be heated?
The quartz tube expansion coefficients are very small, not burst into the water immediately after heating. It is used in heating equipment, in order to make the intermediate electric wire electric heat emitted by the radiation can be fully out, there is a quartz tube, it is the heat emitted by the electric heating wire with radiation, so use the opal quartz tube do electric heating tube, because it is white, inside of the electric heating wire is not easy to see, in fact there is a heating wire. A transparent quartz tube with an ultraviolet characteristic, so ultraviolet germicidal lamp with good transparent quartz tube processing.
Q:What is the difference between an aluminum tube and a quartz tube? What are their advantages and disadvantages? If there is a heating material that is used as an electric heater, which is the best?
Quartz tube and halogen tube belong to the first generation of radiation type electric heater, appeared in 80s and is still in use, this generation of the product life cycle is the longest, now have electric heater manufacturers in the production, the disadvantage of light pollution, short service life (relative to the product after the first generation of electric heater for two) comparison, actually use the common market rate of products almost, and is one of the most common low-end products, the production of mature and stable technology, low price (a good point is around 100) will then think quartz better ~ ~ no reason.
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:Can the electric heating wire in the quartz tube be replaced by an electric tungsten wire?
* wavelengths can be controlled in 0.76um-2um and 2um-16um., and different wavelength heating tubes are selected based on the physical characteristics of the heated object. The thermal efficiency can reach above 86%.* the thermal inertia of the high infrared heating tube is very small. Power up to 0.8 seconds, up to 50% of the rated power, about 1 seconds, up to 80% of the rated power, about 2 seconds up to rated power operation, warming and cooling rapidly.* the high infrared heating tube can spray the heavy metals such as gold and titanium in a certain part of the tube wall to form a directional reflecting layer, which can greatly improve the thermal efficiency and reduce the temperature of the reflecting cover.* the service life of the high infrared heating tube is 3000-5000 hours (depending on the use environment),* the high infrared heating tube itself is small in size, but the power can be very large. Such as Phi 12mm long 300mm heating tube power can be 1KW. My company's products power from 300W-6000W, voltage 110V, 220V, 380V, length from 60mm-2000mm have finished products, and according to the user's needs to produce a variety of non shaped tubes.
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:How do I distinguish the sterilizing cabinet from light wave disinfection and quartz tube disinfection?
Disinfection cabinet quartz tube lights Youmeng is dark red, light strong light, light can burn a piece of paper in a few seconds, the light tube water bursting;
Q:Heater heating mode: quartz tube heating, ceramic heating, far infrared heating, halogen tube heating, I do not know the kind of heating method.
Each has its advantages and disadvantages, mainly depending on the thermal efficiency and the impact on human health.
Q:Is the heater good for quartz tube or electric heating wire?
The best heating element is PTC ceramic, but each heating body has its own shortcomings. If you choose between the quartz tube and the hot wire, my advice is to select the quartz tube.
