UV filtering quartz glass tube is a kind of tubular material made of quartz glass with special function of filtering ultraviolet rays.

I. Material Characteristics

1. High purity:

  - Quartz glass tube is made of high purity silicon dioxide with very low impurity content. This high purity makes it in the ultraviolet region has good transmittance, at the same time can effectively filter out the human body and some materials harmful to the specific wavelengths of ultraviolet light.

  - For example, in some high-precision optical experiments and instruments, high purity UV filtering quartz glass tube is required to ensure the accuracy of the experimental results and the stability of the instrument.

2. High temperature resistance:

  - Quartz glass tube is able to withstand high temperatures, with a softening point as high as about 1730°C. This makes it possible for it to remain in a high-temperature environment. This makes it can still maintain stable performance in high temperature environment, and will not be deformed or damaged due to high temperature.

  - For example, in some high-temperature furnaces, ultraviolet lamps and other equipment, UV filter quartz glass tube can effectively filter ultraviolet light, while withstanding the high temperature environment.

3. Good chemical stability:

  - Quartz glass tube has strong corrosion resistance and hardly reacts with any acid, alkali, salt and other chemicals. This makes it in a variety of harsh chemical environments can maintain stable performance.

  - For example, in some chemical and pharmaceutical industries, it is necessary to use UV filtering quartz glass tube to filter ultraviolet light, and at the same time to prevent the corrosion of chemical substances on the glass tube.

II, the principle of ultraviolet filtration

UV filtering quartz glass tube through a special manufacturing process, adding a specific ultraviolet absorber in the glass or using special coating technology to achieve the filtration of ultraviolet light.

1. UV absorber:

  - In the manufacturing process of quartz glass, some substances capable of absorbing ultraviolet rays are added, such as cerium oxide and titanium oxide. These ultraviolet absorbers can selectively absorb specific wavelengths of ultraviolet light, thus realizing the filtration of ultraviolet light.

  - For example, some UV-filtering quartz glass tubes used in medical equipment need to filter out harmful UV-B (280-320nm) and UV-C (200-280nm) waves while retaining therapeutically beneficial UV-A (320-400nm) waves. Selective filtration of different wavelengths of UV can be realized by adding specific UV absorbers.

2. Coating technology:

  - By plating a special film on the surface of the quartz glass tube, such as metal oxide film, multilayer dielectric film, etc., the reflection or absorption of ultraviolet rays can be realized, so as to achieve the purpose of filtering ultraviolet rays.

  - For example, some UV-filtering quartz glass tubes used in solar water heaters need to filter out the UV rays that are harmful to solar collectors, while retaining the visible and near-infrared light that is helpful for solar energy absorption. By plating a special coating on the surface of the glass tube, it can realize efficient filtration of ultraviolet rays and improve the efficiency and life of the solar water heater.

III. Application Areas

1. Medical industry:

  - In medical equipment, UV filtering quartz glass tubes are commonly used in UV therapeutic instruments, photodynamic therapy equipment and so on. These devices require specific wavelengths of ultraviolet light to treat certain diseases, and the UV filter quartz glass tube can filter out the harmful ultraviolet light, and at the same time to ensure that the ultraviolet light required for treatment can be accurately irradiated to the diseased parts.

  - For example, in the treatment of skin diseases in the ultraviolet ray therapy instrument, the ultraviolet quartz glass tube can filter out the ultraviolet B wave and ultraviolet C wave, reduce the damage to the skin, and at the same time to ensure that the ultraviolet A wave can effectively promote the metabolism of the skin cells, so as to achieve the purpose of the treatment of skin diseases.

2. Laboratory research:

  - In the laboratory, UV-filtering quartz glass tubes are commonly used in instruments such as UV spectrophotometers and fluorescence analyzers. These instruments need to use a specific wavelength of ultraviolet light to analyze and detect, and the UV filter quartz glass tube can filter out the ultraviolet light that interferes with the signal, improve the accuracy and sensitivity of the instrument.

  - For example, in the UV spectrophotometer, the UV filter quartz glass tube can filter out the ultraviolet wavelength of less than 200nm, to avoid these ultraviolet rays on the detector of the instrument to avoid damage to the detector, and at the same time to ensure the accuracy of the measurement results.

3. Industrial production:

  - In industrial production, UV filter quartz glass tube is commonly used in UV curing equipment, printing equipment. These devices need to use ultraviolet light to cure coatings, inks and other materials, and UV filtering quartz glass tube can filter out the harmful ultraviolet light, while ensuring the quality and stability of the curing effect.

  - For example, in the printing industry, UV curing ink can improve the printing speed and quality, and UV filtering quartz glass tube can filter out the UV light in the UV curing equipment, to avoid harm to the operator, while ensuring the curing effect of the ink.

4. Daily life:

  - In daily life, UV filtering quartz glass tube also has certain applications. For example, some high-grade lamps, decorations, etc. may use UV filtering quartz glass tube to filter ultraviolet rays, to reduce the harm to the human body and objects. In addition, some solar water heaters, air purifiers and other equipment may also use UV filter quartz glass tube to improve the performance and life of the equipment.

UV filtering quartz glass tube is a material with special functions, which has a wide range of applications in the fields of medical treatment, laboratory research, industrial production and daily life. With the continuous progress of science and technology, the performance and application areas of UV filtering quartz glass tube will continue to expand and improve.
