Low hydroxyl quartz glass tube

· transparent quartz glass tube

· odorless oxygen quartz glass tube

· UV filtering quartz glass tube

there are three types of quartz glass tubes for light source, so as to meet the requirements of the same light source with some alloys with certain characteristics developed by some companies. Low hydroxyl quartz glass tube is a newly developed product, which is produced with the quartz powder of unimin company in the United States. Its main product performance reaches the level of similar products in the world, and the price is low.%

180 is an industrial standard quartz glass tube. The high-purity transparent quartz glass tube with silica purity greater than 99.97 has high spectral transmittance, low hydroxyl content and low price. Suitable for mercury lamp, halogen tungsten lamp, UV lamp and other quartz glass light sources

230 type is odorless transparent quartz glass tube with large oxygen in the domestic market, which is based on type 80 pure quartz glass with 200ppm titanium oxide added on the basis that its utilization is subject to certain restrictions. It has the property of absorbing far ultraviolet, and is used in the production of ultraviolet sterilization lamp. It is characterized by not passing through ultraviolet light less than 200 nm and preventing oxygen smell caused by 185 nm. Other performances of model 230 are basically the same as those of model 180

360 type is ultraviolet filtering quartz glass tube. It is a titanium cerium doped quartz glass tube, which absorbs UV-B and UV-C ultraviolet rays and maintains good transmission in the visible band. It is suitable for producing light sources with high requirements for UV protection

I. purpose: tube wall material for high-performance, high-temperature electric light sources

II Analysis of typical impurity content (PPM) compared with two-component waterborne polyurethane adhesive (produced with raw materials of unimin company in the United States)
