Q:What is the role of quartz glass tube?
Don't burn red glass into the water without cracking, just burn split. In general, add fresh boiling water will not crack in the glass, the glass is very good, but it still belongs to the category of ordinary glass. The cost of making quartz glass is very high. They are only available where special properties are required.
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:Disinfection cabinet light wave or quartz tube good?
The ordinary quartz tube sterilizer only has the function of high temperature disinfection, and the temperature is slow. According to the quantity of the cabinet (empty cabinet - full cabinet), the heating time should be 30~45 minutes;
Q:Quartz heating tube and carbon fiber, which saves electricity?
Environmental protection comparison: the metal tungsten in the quartz heating tube is a non renewable resource, and the carbon fiber wire is environmentally friendly material, renewable and inexhaustible. The waste carbon fiber thread will not pollute the environment.
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:What is quartz tube for?
Quartz glass tube is made of silica dioxide [1] special industrial technology glass, is a very good basic material. Quartz glass has a series of excellent physical and chemical properties, such as: 1, high temperature resistant quartz glass softening point temperature of about 1730 DEG C, can be used in 1100 DEG C for a long time, short time maximum temperature is 1450 degrees centigrade, 2, corrosion except hydrofluoric acid, quartz glass hardly with other chemical acids the reaction, its acid resistance is 30 times 150 times of ceramic, stainless steel, especially the chemical stability at high temperatures, any other engineering materials are incomparable. 3, good thermal stability of quartz glass thermal expansion coefficient is extremely small, can withstand the temperature changes, the quartz glass is heated to 1100 degrees Celsius, the water will not burst into the room.
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:How do I distinguish the sterilizing cabinet from light wave disinfection and quartz tube disinfection?
Because of the rapid heating rate, the light tube can be instantaneously illuminated, while the quartz tube has a slow heating rate. The light of the quartz tube is dim, and it is slower than the light speed for a few minutes.
Q:What are the uses of quartz tubes?
The requirement for quartz and silica depends on the use of your glass tube.Quartz glass used in semiconductors or optical fibers. The requirement for silica is generally 99.9-99.99%.
We are mainly engaged in developing and producing high-quality quartz glass products and CFQ tubes applied for light-sources, disinfection, chemical tubes, communication and heating equipment, and they are supporting materials for LSI. Our major products include 200-460mm large OD high purity quartz tubes with OH<20ppm, other quartz tubes with OD range from 2 to 200mm, ozone free quartz tubes, UV-stop quartz tubes, twin quartz tubes, (fishing lamps) bulb shells, quartz boats, quartz for vertical furnace, quartz pedestals, quartz tanks, clear quartz crucibles.
