Low hydroxyl quartz tube
Of the advanced even thawing method production technology to produce low hydroxy quartz tube, with high purity, strong transmission, the appearance of clear, low hydroxyl content is manufacturing halogen lamp, mercury lamp, metal halide lamp and other quartz lamps, the material of choice. Hydroxyl content can be controlled according to customer requirements in 10ppm/5ppm/2ppm.
No ozone quartz tube
Cross section micro yellow. The product can intercept 220nm under ultraviolet light, 253.7nm spectral transmittance is 82.5% 500nm, the spectral transmittance is 91.4%. Is an ideal material for UV disinfection and disinfection lamps
Filter ultraviolet quartz tube
The surface is colorless or slightly blue and the cross section is blue. Can be used for the production of multiple types of environment-friendly electric light source products, this product in with ordinary quartz tube and excellent physical and chemical properties, which can effectively filter the ultraviolet spectrum of 190-320nm wavelength of ultraviolet light, and avoid the radiation on the human body.
