タイトルまたは説明

description:The quartz glassware has a series of fine physics, chemistry performance: 1st, thermostable: May in ***0℃ under the long time use; 2nd, anti-corrosive: Besides the hydrofluoric acid, the quartz glass nearly does not have the chemical reaction with other acids material; 3rd, the thermostability is good: not blast when putting in the water after heating to about ***0℃ 4th, the diaphanous performance is good: All has the good diaphanous performance in the ultraviolet ray to the infrared entire spectrum wave band, the visible light transmissibility above *3%, specially in the ultra-violet spectrograph area, the maximum transmissibility may reach above *0; 5th, the electric insulation performance is good: Its resistance value is equal to simple glass *0, **0 times, is the extremely good electric insulation material, even if also has the good electricity performance under the high temperature.
