Description

Doped with trace elements, the red quartz tube, dark red and pink red available, is able to prevent all the UV rays and part of visible light and meanwhile make the most of infrared rays. It is widely used in the field of far infrared heating, such as heater, sterilization tak, microwave oven, electric cooker, electric oven, surface drying, automobile paint baking , etc. Propertues: Infrared quartz tube doped with trace elementshas lustrous apearance, brilliant color, and the same property of heat processing with quartz tube. Appilication: It is another good material for far infrared heating, and also for the stage light Dimensional Tolerance Range of OD WT Siding Ellipticity Camber/***0mm Length(mm) 8.*0±0.*5 1.0±0.*0 *0% 1.5% 2.5mm ***0 9.*0±0.*5 1.0±0.*0 *0% 1.5% 2.5mm ***0 *0.*0±0.*5 1.0±0.*0 *0% 1.5% 2.5mm ***0 *1.*0±0.*5 1.0±0.*0 *2% 1.5% 2.5mm ***0 *2.*0±0.*5 1.0±0.*0 *2% 1.5% 2.5mm ***0 *3.*0±0.*5 1.0±0.*0 *2% 1.5% 2.5mm ***0 Physical Properties Density ******3(×**3) 2.2 Coefficient of expansion *****0 c*1(×***6) 0.5 Softening point() ***0 Annealning point() ***0 Strain point() ***0 Youngs modulus(pa) 7.3×**5
