Introduction of information about quartz tubes

The quartz tube is a special industrial technical glass made of silica, which is a very excellent basic material. Quartz glass is made by melting various pure natural quartz (such as crystal, quartz sand, etc.), which has a series of excellent physical and chemical properties. Quartz glass can be used inside electric fire buckets, electric grills, and electric heaters to generate heat. The following is a brief introduction to quartz tubes.

The following is a list of contents:

  • Physical Characteristics of quartz tubes

  • Chemical characteristics of quartz tubes

  • Test method of the quartz tube

Physical Characteristics of quartz tubes

The physical characteristics of quartz tubes mainly include good thermal stability, good light transmission, and good electrical insulation properties. The coefficient of thermal expansion of quartz glass is extremely small, and it can withstand drastic temperature changes; when heated to about 1100°C, quartz glass will not blow up when placed in room temperature water. Quartz glass in the ultraviolet to an infrared band of the entire spectrum has good light transmission performance, a visible light transmission rate of 93% or more, especially in the ultraviolet spectrum, with a maximum transmission rate of 80% or more. The resistance value of quartz glass is equivalent to 10,000 times that of ordinary glass, which is an excellent electrical insulation material and has good insulating properties even at high temperatures.

Chemical characteristics of quartz tubes

The chemical characteristics of quartz tubes are mainly high-temperature resistance and corrosion resistance. Its high-temperature resistance is mainly reflected in the softening point temperature of quartz glass about 1730℃, which can be used for a long time at 1100℃, and the maximum use temperature for a short time can reach 1450℃. Its corrosion resistance is mainly reflected in the fact that, except for hydrofluoric acid, quartz glass almost does not react chemically with other acids, and its acid resistance is 30 times that of ceramics and 150 times that of stainless steel, especially its chemical stability at high temperatures, which is incomparable to any other engineering materials.

Test method of the quartz tube

Generally speaking, the main test is the resistance value and supply voltage of the quartz tube. First of all, we will introduce some methods to test its resistance value. By using a multimeter to detect its resistance value, the multimeter block to "beeping block", the red and black meter pen respectively on its two ends, at this time the multimeter buzzer should sound, and the pointer should point to zero. If the test, the multimeter buzzer no sound, and the pointer points to infinity, it means internal damage. Next, introduce the quartz tube supply voltage is how to detect it. The range of the multimeter to "AC 250V" voltage block and the red and black meter pen is on its power supply side. At this time observe the multimeter readings, if the AC is 220V or so, it means that the supply voltage is normal.

In recent years, the application of quartz glass has gradually become common. To ensure the quality of quartz products, the company and the product supervision department should keep up with the times, do sufficient risk analysis, improve inspection standards, and finally improve product quality and ensure product safety for people to use. After reading the above, if you are interested in quartz tubes, you can visit our company's website, we are looking forward to your arrival.
