CeO 2Mainly has the ultraviolet radiation absorption function; CeO 2This joins in the glass batch as coloring agent component as the colourless powder shape, can produce and be essentially water white glassy product; The too low preventing ultraviolet effect of content is good inadequately; Content is too high, as is higher than 2.5wt% content, and its oxygenizement is too strong again, and yellow tone also appears in the tone of glass easily; In addition, the too high meeting of content causes raw-material cost to increase; So control CeO among the present invention 2Content at 1.1-2.5wt%; Preferably, CeO 2Content is 1.2-1.9wt%.
TiO 2Be colourless or pale yellow powder, also mainly have the ultraviolet radiation absorption effect; TiO 2Between the content of ferrous iron and ferric oxide, cobalt, chromium, need to reach a suitable balance, like this tinting material the blend of colors stack that produces separately, thereby obtain to have the ultraviolet ray intercepting glass of required spectrum property; When making ultraviolet ray intercepting glass, frequent and CeO 2Use together, preventing ultraviolet effect is better, but will control its consumption; Consumption is too low, does not have due preventing ultraviolet effect; Consumption is too high, also yellow tone can occur; The present invention controls TiO 2Content is at 0.01-0.19wt%; Preferably, TiO 2Content is controlled at 0.03-0.15wt%.
CoO is the blue colorant of stiff stability very, also can play the effect of weak infrared radiation absorption agent; Content is too high, and its tinting strength is too strong; Content is too low, does not have enough coloring effects again; It is 0.1-35PPM that the present invention controls its content.
Cr 2O 3Be to make glass present green tinting material; It also has certain ultraviolet absorption ability in addition; And help the final color of feed glass.Content is too high, and the color is too dark; Content is too low, does not have enough coloring effects again; It is 5-200PPM that the present invention controls its content.
Above tinting material comprises Fe, CeO 2, TiO 2, CoO and Cr 2O 3Deng, need be at Fe 2O 3, FeO, CeO 2, TiO 2, CoO, Cr 2O 3Content between seek a suitable balance, and the redox condition in the control melting furnaces, thereby the ultraviolet ray intercepting glass that could obtain to have described optical property.
The present inventor selects various mineral or chemical feedstocks preparation admixtion according to the per-cent of various compositions in the ultraviolet ray intercepting glass, drop into silica sand, soda ash, rhombspar, Wingdale, saltcake, cobalt oxide, selenium, chromite, SODIUMNITRATE, titanium oxide, ferric oxide, carbon dust to melting furnaces, SODIUMNITRATE wherein is that oxygenant, carbon dust are reductive agent, both play redoxomorphism, and consumption is adjusted according to the redox coefficient; Saltcake has clarification; Cobalt oxide, selenium, chromite, titanium oxide, oxidation iron rule are to play pigmentation.
