Quartz glass has a very low coefficient of thermal expansion, high temperature resistance, excellent chemical stability, excellent electrical insulation, low and stable ultrasonic delay performance, the best UV-Vis spectral performance and visible and near infrared spectroscopy Performance, and has a higher than ordinary glass mechanical properties.
A method for producing a large-diameter quartz glass tube is to put quartz sand raw material into a crucible of a melting furnace, reduce the crucible to a minimum through the upper cover, and melt the molten material into a liquid, and the liquid is discharged at a high temperature and then discharged through a vent hole. Gas impurities and liquid impurities, the crucible is lifted through the upper cover, and the liquid enters the molding machine table for molding, and the raw materials are continuously added to the crucible. Finally,the expanded quartz glass tube is sequentially cut off at both ends, acid Wash, ultrasonic cleaning, annealing.
