Abstract
A blue-tinted glass which, in its non-darkened state, is a true blue, darkened upon exposure to actinic radiation, particularly short-wave visible light and ultraviolet light, and appears blue or bluish-grey. The color-changing glass is produced by adopting an aluminoborosilicate system, introducing various additives such as silver halide, metal oxide and the like, and adopting common optical glass smelting equipment and a smelting method. The color-changing glass is ground into thin sheets, can be used as optical filters of television display terminals, sunglasses, myopia glasses, presbyopic glasses and the like, and brings comfortable and beautiful enjoyment to people. The color-changing block has good fading effect, good absorption to short-wave visible light and ultraviolet and positive protection effect on human eyes.
Description
The invention belongs to the photo chromic glass field.Be pure blueness under non-deepening state, accepting actinic radiation, particularly the irradiation deepening of short wave ultraviolet is blue or bluish grey photo chromic glass product and production method.
Photo chromic glass has following properties usually: photochromic glass places actinic radiation, particularly deepening under the radiation of short wave ultraviolet, and behind the removal actinic radiation, glass is recovered lost eyesight or is return original tone.United States Patent (USP) u.s.p3208860 reports at first; U.s.p4,190,451 have set forth and have improved deepening, and express silver halide photo chromic glass fades; U.s.p3892582 and 3920463 the explanation with thermal treatment reach the permanent table face colouring and under reducing atmosphere heat treated variable color goods, can obtain upper layers such as pink, yellow, dark brown; U.s.p4240836 has introduced thermal treatment under reducing atmosphere, can obtain from indigo plant to the orange photochromic glass goods of the surface colour from red to purplish red; U.s.p4537612 has introduced photo chromic glass after 16 hours ion exchange treatment, handles down through reducing atmosphere again, can obtain purple, only handles under reducing atmosphere without ion exchange treatment, can obtain the orange of surface colour.
Photo chromic glass and production that above-mentioned patent document is introduced, the method that obtains specific color under non-deepening state is very complicated, and the production cycle is long, and the cost height also needs special equipment and heat-treats under reducing atmosphere, and is difficult to obtain pure blueness.
Task of the present invention is the deficiency at above-mentioned photo chromic glass, and a kind of blue discolouration glass is provided, and presents pure blueness under non-deepening state, is dark blue or pewter after the deepening.It is good that this blue discolouration glass has color shifting properties, and it is worn into thin slice, can be used for the spectral filter of video display terminal (VDT) and camera gun, not only improves contrast gradient, can also reduce reflection, reduces the staff's of long-term observation display terminal visual fatigue; Also can be made into the needs of optics aspects such as sun glasses, near-sighted glasses and old light microscopic.

The production technique of blue discolouration glass:
1. prepare burden
Take by weighing starting material after pulverizing, sieve and measuring moisture by above-mentioned recipe ingredient, place in the hopper to mix, add silver nitrate aqueous solution again, fully mix thoroughly, standby.
2. found
Select conventional tank furnace or globars electric furnace for use, platinum crucible and platinum agitator (electric furnace heats up with 50-60 ℃/hour speed) are housed, begin to add the material of mixing thoroughly at 1400 ℃, because the powder specific volume is big, add several times, add 1/2nd of crucible for the first time, add 2/3rds of crucible for the second time, add to flat crucible later on, until adding at every turn.Note material not being sprinkling upon outside the crucible, in the intensification clarification stage, temperature does not rise too suddenly, allows the abundant slaking of material, in order to avoid send out cylinder.The homogenizing clarifying temp is 14.50 ± 15 ℃, and high temperature stirred 6～13 hours with (with 60～70 rev/mins), generally can eliminate bubble.Can the sampling correction specific refractory power in the stokehold, observe striped, bubble.Bubble can or improve mixing speed and adjust by the proper extension settling time.1400 ℃ of bottom discharges, glass is poured into iron plate go up moulding, be pressed into 5～6 millimeters thick sheet glass again.
3. thermal treatment
Above-mentioned sheet glass is placed in the heat treatment box, be incubated 0.5-6 hour down at 620-680 ℃, outage cools the temperature to the room temperature discharging then, is blue discolouration glass product of the present invention.
The discoloration of blue discolouration glass and physical and chemical performance
With the sheet glass after the thermal treatment, become 1.8 ± 0.1 millimeters sample through attrition process, at room temperature test:

Advantage of the present invention:
1. production technique is simple, adopts general opticglass melting equipment and melting method all can produce blue discolouration glass, need not heat-treat under reducing atmosphere, does not also need ion exchange treatment just can make aforesaid blue discolouration glass.
2. because technology is simple, reduce energy consumption, saved man-hour, reduced cost.The also available tank furnace scale operation of photo chromic glass of the present invention realizes the commercialization of product.
3. blue discolouration glass is worn into thin slice, can be used as the spectral filter of video display terminal (VDT), not only can improve contrast gradient, can also reduce white picture reflection, thereby alleviate display terminal office worker's eyeball fatigue.Before being installed on the colour TV screen, can reduce of the stimulation of colored high light, prevent to watch for a long time people's visual deterioration of colour TV human eye.
4. glass of the present invention also can be made sun glasses, near-sighted glasses and old light microscopic, gives the wearer with comfortable and beautiful enjoyment.Particularly the near-sighted glasses wearer comes under the intensive sunlight from indoor, need not change glasses, light-sensitive glasses of the present invention just rapidly deepening be dark blue tone or pewter, good to shortwave light and UV absorbing properties, human eye is played positive protective effect.
5. it is fast that blue discolouration glass of the present invention has variable color speed, and it is effective to fade, the characteristics of tone gracefulness.
