Quartz sight glass /pryex sight glass
1 resistance high temperature
Quartz glass's softening point temperatureapproximately 1730°C can in 1100°C under the long time use, in the short timethe highest application temperature be possible to reach 1450°
2 resistanceto corrosion
Corrosion-resistant. In addition to hydrofluoric acid, thequartz glass is almost non-acid substance with other chemical reactions, itsacidproof ability is ceramics' 30 times, stainless's 150 times, especially inthe high temperature chemical stability, is any other engineering materialscannot be compared
3 Excellent thermal stability
Coefficient of thermalexpansion of quartz glass, is extremely small, able to withstand drastictemperature changes, quartz glass heated to 1100 or so, will put in often in thelukewarm water not to blast open.
4 Transmittance of good performance
Thediaphanous performance is good. The quartz glass in ultraviolet has the gooddiaphanous performance to the infrared entire light wave band, the visible lighttransmissibility above 93%, specially in the ultra-violet spectrograph area, themaximum transmissibility may reach above 80%.
5 great electrical insulation properties
quartz glass's resistance valueis equal to simple glass 10,000 times, is the extremely good electric insulationmaterial,even at high temperatures also has good electricalproperties.
