The following describes the present invention is absorbed the reason that the composition of ultraviolet ray, infrared transmitting glass limits by force, below all percentage number averages be weight percentage.
SiO
2Be the main component that constitutes the glass skeleton, can reduce the thermal expansivity of glass, improve thermostability, chemical stability, softening temperature, thermotolerance, hardness, physical strength and the viscosity etc. of glass.Content is low excessively, and the various performances of glass can descend, too high levels, and raw material is difficult to fusing.
Na
2O is the outer oxide body of glass network, can reduce the viscosity of glass, make glass be easy to fusion, be the good solubility promoter of glass, but it can increase the thermal expansivity of glass simultaneously, reduce thermostability, chemical stability and the physical strength of glass, so can not introduce too much, generally be no more than 18%, introduce very fewly, the fusing effect of glass is just poor.
CaO is the outer oxide body of glass network, and the main effect in glass is a stablizer, promptly increases the chemical stability and the physical strength of glass, but content increases the crystallization tendency of glass, and easily make the glass embrittlement when higher, generally is no more than 12.5%.
Ferric oxide is a kind of impurity that contains in the sandstone, and its existence form has FeO and Fe
2O
3Two kinds, FeO can make glass be blue-greenish colour, Fe
2O
3Can make glass be yellow-green colour, the tinting strength of low price iron is approximately 10 times of high price iron tinting strength.No matter be the transparency that high price iron or low price iron all can reduce glass,, influence the quality of glass so the iron-holder increase can reduce transparency and glossiness in the glass.Fe
2+And Fe
3+Ultraviolet ray all there is the intensive sorption, but Fe
2+Infrared rays had intensive sorption, Fe
3+Infrared rays there is not sorption substantially.
Carbon dust is a kind of high temperature reduction agent, can be with Fe under the hot conditions
2O
3Be reduced to FeO, but in glass carbon powder content roll up can not be with Fe
2O
3Be reduced to FeO fully, can only reduce the Fe of small part
2O

Tin protochloride is colourless or white oblique system crystallization.Relative density 2.710.37.7 ℃ of fusing points.Under fusing point, be decomposed into hydrochloric acid and subsalt.In air, be oxidized to insoluble oxychloride gradually.Be a kind of reductive agent, can be with most Fe in the glass
2O
3Be reduced to FeO fully.
The present invention absorbs ultraviolet ray by force, infrared transmitting glass has higher visible light transmissivity, can absorb ultraviolet ray and infrared rays consumingly, and can directly on the basis of common float glass batch materials, carry out the composition design, and can realize suitability for industrialized production, lower and the economic environmental protection of cost is the optimal selection of protective glass such as automobile, building, spectacle glass and laboratory apparatus.
