Detailed Description

UV-stop quartz tube： 1. UV stop glass tube is doped Ce，can stop nearly all the radiation of ultraviolet ray of UV-B,UV-C and all of ultraviolet ray of UV-A,it is the ideal material of the most spectral transmission 2. it is widely used in quartz halogen lamps,high density discgarge lamps and other UV light 3. efficient,healthy,no harm to health,no pollution,economic,long life 4. it can adjust temperature of space automatically 5. dinmension tolerance Range of OD OD WT Siding Out of round Bow/1220mm ≤6mm ±2.0% ±10% 12% 2.0% 2.5mm 6.00-15.00mm ±1.25% ±8% 10% 1.5% 2.5mm 15.00-20.00mm ±1.25% ±10% 15% 1.5% 2.5mm 20.00-25.00mm ±1.25% ±10% 15% 1.5% 3.0mm 25.00-30.00mm ±1.35% ±12% 15% 1.5% 3.0mm 6. chemical composition Cr Ge Fe Mg Ti Ca Al Na Li K 羟基OH 20 0.4 1.5 0.4 4.6 1.0 16 2.3 0.5 2.0 ＜25 7. spectral transmission at 1.0mm thickness Nm ≤220 255 280 315 350 380 590 780 % 89 91 93 93 93 93 93.2 93.4 8. physical properties Density 20℃kg.m﹣3 2.2 Coefficient of expansion 25-300℃℃﹣1 0.58 Softening point(℃) 1670 Annealning point(℃) 1210 Strain point(℃) 1110 Youngs Modulus 7.3×105 9.
