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 properties. Be characterized by:1, high temperature resistance, quartz glass softening point temperature of about 1730 degrees Celsius, can be used at 1100 degrees for a long time, the shortest use temperature of up to 1450 degrees celsius,2, except hydrofluoric acid corrosion, quartz glass and other acids almost no chemical reaction, the 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.4, good light transmission performance of quartz glass in the ultraviolet to the infrared spectral band has good light transmittance, visible light transmittance is more than 93%, especially in the ultraviolet spectral region, the maximum transmittance is higher than 80.5, the electrical insulation performance is good, quartz glass resistance value is equivalent to ten thousand times of ordinary glass, is excellent electrical insulation material, even in high temperature, also has good electrical performance.
Easy damage is the inside of the heating resistance wire. If the heating resistance wire is broken, it needs to be replaced. It can be pulled out and put into a new heating resistance wire, and it can continue to be used.
The general electric heater adopts the quartz tube to heat up. It is to wear the resistance wire in the quartz glass tube, two end are not sealed, therefore the quartz glass tube can not damage (unless man-made interrupts).
