Description
Technical field:
The present invention relates to a kind of green glass that selective solar spectrum is absorbed, it belongs to field of glass production technology, particularly the production technical field of tinted shade.
Background technology:
In the prior art, two class glass compositions are arranged at present.Wherein a class complete processing is complicated difficult, and the production cost height has been introduced a kind of low infrared transmittivity and the glass of ultraviolet permeability as U.S. Pat 4792536, and this glass is that soda lime system and glass present blueness, and wherein FeO accounts for Fe in the glass
2O
3Ratio greater than 45%.Because this kind glass FeO accounts for total Fe in the glass
2O
3Large percentage, require under negative pressure state, to clarify, simultaneously in the glass the saltcake of normal use can not make finings, this bring great difficulty will for the production of routine, and will be equipped with proprietary clarification equipment.
Another kind of is to have adopted a high proportion of total iron content and a high proportion of CeO
2Composition.Disclosed a kind ofly as CN1043034C, has not said and under negative pressure state, to clarify, its FeO total Fe in glass although its is introduced to radiation of sun the subject of knowledge and the object of knowledge and the low glass of ultraviolet (uv) transmission
2O
3Ratio the highlyest also reach 38%.This results in hand cramps also can for conventional (float glass process) glass production, and adopts a high proportion of CeO
2Content (maximum amount is 2.0%).Chinese patent CN1027635C Chinese patent discloses a kind of green glass composition that absorbs infrared and uv-radiation that relates to, and its highest iron level is 0.96%, CeO
2Content is 1.4%, TiO
2Content is 0.85%; Its principal character is that visible light transmissivity is greater than 70% under the twinkler A light, and total sun power transmitance is less than 46%, and ultraviolet permeability is less than 38%.Chinese patent CN10899730C discloses a kind of green glass composition of infrared and uv-absorbing, and it has adopted iron, cerium, titanium and chromium to produce needed color and optical property, its CeO
2Content is 0.9-1.4 weight.Three kinds of above glass compositions are owing to adopted the total iron content of height ratio row and the CeO of height ratio row
2Composition causes the too high of production cost on the one hand, also brings the defective of striped on the other hand easily to glassy product.
Summary of the invention:
The object of the present invention is to provide and a kind ofly can select to absorb to the UV spectrum in the solar spectrum, filter the harmful light in the sunlight, and complete processing is simple, production cost be low, the green glass that the general selectivity of sunlight is absorbed that glass appearance is effective.

3About 4--20PPM.It can realize the glass to solar spectrum medium ultraviolet light and the selective absorption of infrared light, the particularly absorption of UV-light, do not influence simultaneously visible light transmittance again, for 5mm heavy sheet glass illuminant D65 light source, transmission of visible light＞70%, ultraviolet transmission rate＜16%, predominant wavelength is at 495～520nm, present green, total sunlight transmitance (TSET)＜41%.
Iron is selected absorption agent as main spectrum among the present invention, particularly as ultraviolet and infrared absorbing agents.Its too high levels makes visible light transmissivity on the low side on the one hand, and can bring bigger infringement to melting furnaces; If content is low excessively on the other hand, can make ir-absorbance on the low side again, ultraviolet permeability is higher.Know in this area, iron in glass with Fe
2O
3There is Fe with two kinds of forms of FeO
2O
3A kind of good uv-absorbing agent, FeO are a kind of infrared absorbing agents.Term " redox ratio " be meant ferrous iron (representing) with FeO divided by total iron (with Fe
2O
3Expression), " redox ratio " surpasses 30%, and traditional melting process just is difficult to produce.
CeO
2As main uv-absorbing agent,, just do not reach the purpose of strong absorption UV-light if add-on is too low, otherwise Tai Gao can make production efficiency reduce again, and has improved cost, and easily influences the chemical equilibrium of other coloring ions in the glass, make painted being in an unsure state, produce the defective of striped.
TiO
2Also be a kind of strong uv-absorbing agent, it is yellow that it produces glass.Cr
2O
3Be a kind of auxiliary uv-absorbing agent, it makes glass produce yellow-green colour, can the final color of stabilized glass.TiO
2And Cr
2O
3As replenishing of uv-absorbing, but reinforced glass uv-absorbing function not only can also reduce CeO greatly
2Consumption.
Co
2O
3Be a kind of weak infrared absorbing agents, it can help to reduce the redox ratio of total iron consumption and glass, and adjusts the color of glass, makes production easier carrying out on traditional technology of this glass.
Obtaining low sunlight transmitance, mainly is to reduce ir-absorbance, from as can be known aforementioned, improves the ratio of FeO in the glass, can reach this purpose.Can take two kinds of means: (1) improves C powder ratio in the glass for this reason; (2) total iron content improves corresponding FeO ratio in the raising glass.But the ratio that increases substantially both will be very unfavorable to producing all.CeO
2In preparing glass charge be strong uv-absorbing agent be again strong oxidizer, if usage ratio is too high, under the constant situation of total iron, the FeO ratio will be descended significantly, cause the sun power transmitance higher.Therefore, the present invention abandons traditional high CeO
2The way of concentration, adopt medium CeO
2Concentration (0.15-0.50%), use a small amount of Cr
2O
3Remedy and strengthen the ability of uv-absorbing, make bulk glass remain on level preferably, utilize Co simultaneously the absorption of ultraviolet
2O
3Weak infrared absorption characteristic, the consumption of control C powder, thus remedy because of using CeO
2And cause the decline of FeO ratio, Cr simultaneously
2O
3Green that can stabilized glass, Co
2O
3Can regulate glass and make us unhappy yellow.
In the present invention, the tinting material that adds in glass is formed can be an oxide form, do not get rid of other form yet, as element form, also can be used in the batching composition, but in batching fusion and purified process, it will transform into the oxide form of the disclosed scope of the present invention, equally also be comprised by feature of the present invention.
