Quartz sight glass(round sight glass)

1 resistance high temperature Quartz glass's softening point temperature approximately 1730°C can in 1100°C under the long time use, in the short time the highest application temperature be possible to reach 1450° 2 resistance to corrosion Corrosion-resistant. In addition to hydrofluoric acid, the quartz glass is almost non-acid substance with other chemical reactions, its acidproof ability is ceramics' 30 times, stainless's 150 times, especially in the high temperature chemical stability, is any other engineering materials can not be compared 3 Excellent thermal stability Coefficient of thermal expansion of quartz glass, is extremely small, able to withstand drastic temperature changes, quartz glass heated to 1100 or so, will put in often in the lukewarm water not to blast open. 4 Transmittance of good performance The diaphanous performance is good. The quartz glass in ultraviolet has the good diaphanous performance to the infrared entire light wave band, the visible light transmissibility above 93%, specially in the ultra-violet spectrograph area, the maximum transmissibility may reach above 80%. 5 great electrical insulation properties quartz glass's resistance value is equal to simple glass 10,000 times, is the extremely good electric insulation material, even at high temperatures also has good electrical properties.
