By table 1 design data by calculating, take silica sand, the CaCO of different amount
3, MgCO
3, Na
2cO
3, tetrahydrate manganese chloride (MnCl
24H
2o) and carbon dust make glass batch, putting into specification after mixing is that the corundum crucible of 150ml is founded.Use SGM3816C chamber type electric resistance furnace, top temperature controls at 1488 DEG C, is incubated 180 minutes at this temperature, makes the abundant melting of glass batch, homogenizing.Take out the corundum crucible filling glass metal to pour into rapidly in the circular die being preheated to 600 DEG C.The resistance furnace that mould puts into another insulation 600 DEG C together with glass sample is annealed.Closed furnace door, powered-down makes glass sample naturally cool to room temperature, and this glass sample is 1#.Repeat again to found twice to 1# sample, namely obtain three 1# samples.Same method makes the glass sample of other correspondence.The glass sample founded is taken pictures under natural light, as shown in Figure 1.
3, carbon powder content change is on the impact containing manganese glass colourity
Change carbon powder content in preparing glass charge, found by under condition described in 2.2 paragraphs, obtain 1#, 2#, 3#, 4# glass sample as shown in Figure 1.
Chromaticity index mensuration is carried out to this series of samples, result such as table 2. JFY-PS color analysis instrument (Research Inst of Textile Industry, Tianjing City) carries out colorimetric analysis to founding gained sample, in following table 2, a, b are the chroma data on chromaticity diagram, a and b represents color direction :+a is red direction,-a is green direction, and+b is yellow direction, and-b is blue direction, and data are larger, correspondence direction color is darker.
Table 2. changes carbon powder content glass determination of colority result in preparing glass charge
| Numbering | C(mol) | a | b |
| 1# | 0.1 | -0.394/-0.392/-0.396 | 15.611/15.596/15.601 |
| 2# | 0.2 | 2.041/2.041/2.041 | 34.495/34.495/34.495 |
| 3# | 0.4 | 3.223/3.223/3.223 | 45.895/45.895/45.895 |
| 4# | 0.6 | 5.008/4.997/5.004 | 50.396/50.399/50.404 |
| 5# | 0.7 | 5.112/5.114/5.109 | 50.400/50.416/50.389 |
| 6# | 0.8 | 5.104/5.112/5.008 | 50.411/50.406/50.419 |
| 7# | (NaNO 3)0.05 | 28.582/28.569/28.572 | 6.709/6.714/6.703 |
By in table 2,1# to 6# sample increases carbon consumption successively in batching, and 7# sample does not add carbon and adds SODIUMNITRATE.Low because adding carbon amounts in 1#, color sample is close to colourless; 2#, 3#, 4# color is deepened successively, 5#, 6# sample carbon consumption increase but color close to 4#; 7# sample is purple because adding SODIUMNITRATE.The repeat samples data that table 2 measures can find out that chromaticity index a, b circulation ratio is good.
4, beneficial effect explains (analysis of causes)
Fig. 2 is the curve of spectrum made 2#, 3#, 4# sample in above-mentioned table 2 of SP-1920 twin-beam ultraviolet-visible pectrophotometer (Shanghai Spectrum Apparatus Co., Ltd.).
1# preparing glass charge adds less carbon dust (0.1mol), and a small amount of carbon only makes the manganese of part be converted into lower valency (Mn
3+→ Mn
2+), do not have unnecessary carbon to participate in painted, at this moment glass coloring ion major part is Mn
2+and the Mn of trace
3+, Mn
2+painted very weak in glass, make the curve of spectrum not peak value display substantially, each fluctuation light is substantially even through, the curve of spectrum as corresponding in 1# in Fig. 3.The outward appearance of glass sample is close to colourless (in Fig. 1 1# counter sample).
Add carbon amounts in 2#, 3#, 4# sample correspondence batching to increase successively, glass batch is at reductibility state, at this moment Mn
3+→ Mn
2+, and more C participates in painted, and coloring ion at this moment has a large amount of Mn
2+and the Mn of C and trace
3+, the curve of spectrum is presented at 600nm-630nm wave band to be had larger through peak, and the outward appearance of glass sample is yellow (in Fig. 1 2#, 3#, 4# counter sample).As can be seen from Figure 2,2#, 3#, 4# sample spectra curve through peak position along with the downward translation of the increase of carbon content in sample, this is because increase with carbon amounts in batching, participating in painted carbon increases, and the color burn of glass, makes glass transmitance reduce.
Found out by the determination data of table 2,5#, 6# sample along with the further increase of carbon consumption, data and 4# sample close because excessive carbon volatilizees with the form of gas, no longer participate in painted, the color of glass no longer changed.
Add 0.05mol SODIUMNITRATE in the preparing glass charge of 7# sample, prepare burden in oxidisability state, the main coloring ion in glass is Mn
3+, the curve of spectrum shows larger absorption (in Fig. 3 7# homologous thread) at 450nm-530nm wave band, glass sample outward appearance display purple.If Fig. 4 is sample contrast.
In sum, in the present invention, when the consumption of carbon dust increases gradually between 0.1mol-0.6mol, the yellow of glass is deepened; When carbon dust consumption is fixed, data stabilization, illustrates the colour stable of glass.
The above, it is only preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, although the present invention discloses as above with preferred embodiment, but and be not used to limit the present invention, any those skilled in the art, do not departing within the scope of technical solution of the present invention, make a little change when the technology contents of above-mentioned announcement can be utilized or be modified to the Equivalent embodiments of equivalent variations, in every case be the content not departing from technical solution of the present invention, according to technical spirit of the present invention to any simple modification made for any of the above embodiments, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
