Milk White Spiral Quartz Glass Coiled Tube for Heating Furnace
Available to absorb the far infrared spectrum with wavelength under 4 U, it makes the tube body itself heat and increase the heat energy radicalization.
We hope to emphasize the emphasis on the quality of Semicondunctor Quartz Crystal Rod, Quartz Crucible Ceramic, Large Size Quartz Cylinder, strengthening the construction of the product lines, consolidating the bases and strengthening the bases of the company. We actively create a good atmosphere of respecting knowledge, labor, creation and talents, and build a talent mechanism suitable for the development of the company. We build confidence with strength, create reputation with performance, and dance out our essence and brilliance in the increasingly fierce market competition. We will further improve the internal management system of the enterprise, enhance market competitiveness and improve the popularity of the company.

Available to absorb the far infrared spectrum with wavelength under 4 U, it makes the tube body itself heat and increase the heat energy radicalization.
At the meanwhile, the wavelength at 5-13 U area far infrared wave bands transmit rate reach onto 90%. material needing heat to dry (it is generally at 3-25u areas,it has strong absorption) Offer most effective alternative absorption to heat material component. This feature is not available with any other far infrared material.
