Uv glass is added into ordinary silicate glass vanadium titanium oxide, oxide, ferric oxide and other metal oxides, and strictly control the melting mood, with good performance can be obtained ontology absorption type uv glass. So now have a special uv glass. Uv glass refers to have to stop (reflection or absorption), ultraviolet (uv) < 0.3 mu (wavelength) of electromagnetic waves through the function of the glass. Most of the common glass has a different degree of function of absorbing uv. Insulated glass is a kind of glass performance, it same as bullet-proof glass has a special performance, and the different is that it can heat insulation. Insulated Glass Manufacturers http://www.constructionGlassbiz.com/product/Double-Glazing-Glass-Insulated-Manufacturers-Suppliers.html divided Insulated Glass into three XRB1 XRB3, coating, heat insulation glass, three types of glass was slightly glaucous close to colorless glass. Including XRB1 is phosphate absorbing glass; XRB3 is absorbed silicate glass; Coated insulating glass heat insulation nano powder block. Turquoise uv and heat insulation glass not absorb visible light but they absorb large amounts of heat near-infrared light, which XRB1, XRB3 needs in the light intensity is high and in addition to the heat insulation performance characteristics under the condition of the most obvious. And good coating hot glass used in construction can directly reduce the temperature, the temperature difference around 3 ? - 6 ?. Uv transparent glass, as the name suggests is that it can filter uv special transparent optical glass, in a nutshell is the uv glass is transparent. |
Currently on the market of uv transparent glass, according to product structure distinguish, basically has the following two groups of three varieties ,according to Insulated Glass Manufacturers : Monolithic structural type: Class A products: the uv glass has the effect of high and low temperature resistant, uv cut-off rate between 35% and 45%. Class B products: the uv 200%, efficacy is A kind of heat-resistant glass products, uv cut-off rate is about 90%. Composite structured: C class product: the uv glass also has the effect of high and low temperature resistance, uv cut-off rate is greater than 99%, is all uv glass products, the best efficacy. Three things in common:
Visible light transmittance is more than 90%, uv cut-off are not restricted by age, and uv protection function is a molding, late without secondary processing.
