Q:What are the hazards of the quartz tube electric heater?
Radiation in a radiant heater refers to the way heat is released. The electromagnetic radiation produced by it is not harmful to adults, but it has certain effects on pregnant women and infants.
Q:The quartz tube that has just changed into the sterilizing cabinet will soon burn out. Why?
If it is easy to burn out, the position of the quartz tube can be replaced by the old tube, but the old tube position is not good soon. It must be the new quality problem. Perhaps manufacturers of sterilized cabinets use quality quartz tubes to improve the quality of the overall product, which makes it difficult to obtain good quality fittings.
Q:What's the difference between a quartz tube and a halogen tube?
Carbon tubes do not have this kind of image, and the light band adapts to the human skinLight emitting / heating: halogen tube light is very bright, part of the energy is converted into light energy, and part of it is converted into heat energy to releaseCarbon tube light is not bright, mainly the energy most of the conversion can heat energy issueTherefore, the same power size of carbon tubes, heating is better than halogen tubesNote: carbon tube is also an energy-saving products: carbon tube 700W can achieve halogen tube 1000W heating effect
Q:The vacuum sealing problem of quartz tube is discussed
The process of pumping quartz is a special vacuum pumping machine. After pumping, it can be sintered and sealed at the upper end of the test tube by high temperature. The pipe can only be used once. General quartz tube radius can not be too big, and vacuum machine mouth on the general 5mm or so, the length to have a dozen centimeters, because too short, when sintering, will affect the sample.
Q:Halogen tube, quartz tube, carbon fiber, which is good?
Quartz electric heating tube, halogen and carbon fiber heating tube are different. The quartz electric heating tube is not sealed, and has the characteristics of moderate heating rate, moderate brightness and long service life. The cheapest and brightest two halogen tube is sealed. The heating tube is a kind of quartz tube. It is made of quartz glass tube, and the heating wire inside it is tungsten wire. It is filled with inert protective gas. Slightly expensive, darkest national standard: halogen heating tubes 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:Can quartz tubes produce infrared rays?
Quartz glass tube is made of silica dioxide special industrial technology glass, is a very good basic material. Quartz glass has a series of excellent physical and chemical propertiesFor electric fire bucket, electric heating stove, electric heater, heating up.
Q:Which is better, quartz glass heating tube and PTC heating tube?
PTC is a relatively new heating material with no thermal expansion coefficient and fast heating, but the heat transfer is slower than the quartz tube under the influence of efficiency.
Q:What's the difference between a quartz tube, an enamel tube and a glass tube?
Glass tubes are made of ordinary glass and have less heat resistance.
Q:Mini small sun is the heating of electric heating or quartz tube heating better?
Before, quartz tube is more suitable. It's bright, but not very bright. It's good for safe use. Non luminous carbon fiber tubes, I think, may be misleading in actual use and cause failure.
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.
