Abstract
A kind of production method of blue heat-absorbing float glass, be characterized in a certain amount of silicon-dioxide, aluminum oxide, calcium oxide, magnesium oxide, a valent metal oxide, cobalt oxide and ferric oxide mixing, put in the melting furnaces and melt, again with the liquid material by behind the molten tin bath, annealing furnace, carry through cutting, packing is finished product.The present invention is owing to adopted the cobalt oxide that is difficult for appraising at the current rate and the ferric oxide that color is not produced considerable influence that appraises at the current rate is that tinting material carries out composite coloration, so the product visible light transmissivity is big, the direct solar radiation transmitance is little, the sight line that makes glass neither hinder the people has good sunshading and heat-insulating effect again.
Description
The invention belongs to production glass technology field, specifically a kind of reparation technology of blue heat-absorbing float glass.
As everyone knows, the glass that has color commonly used at present has: cranberry glass, smoked glass and covellite glass, the tinting material that these glass adopted are respectively chemical elements such as selenium, nickel, copper.Because above-mentioned chemical element is very unstable in producing the glass process, appraise at the current rate easily and volatilization loss, control so adopt under redox agent and the fusing atmosphere, making to produce increases the control difficulty, therefore often causes the misalignment of glass.See that in quality above-mentioned the former two's product shade is dark, it is dull, oppressive to give sensation, loses people's magnetism gradually.Though latter's tone is lucid and lively, do not have good heat absorption capacity, can't satisfy the needs that modernized high-rise uses.
The purpose of this invention is to provide a kind of color and luster stablizes lucid and lively and increases the production method of the blue heat-absorbing float glass of heat absorption capacity.
The object of the present invention is achieved like this: its concrete production method is:
(1), by the percentage composition of following finished glass composition, raw material silica sand, ground silica, rhombspar, Wingdale, fluorite, soda ash, saltcake, coal dust, cobalt oxide powder, brown iron oxide are dropped into uniform mixing in the mixer;
(2), the material with mixing is input in the furnace hopper, enter in the melting furnaces by the roller charging machine, under 1480-1600 ℃ that material is molten for liquid, after again the material of liquid state being annealed by tin groove forming, annealing furnace, be blue heat-absorbing glass finished product through cutting, packing, its finished product oxide compound (weight percent) is: SiO
2: 70.0-71.0, Al
2O
3: 2.5-3.0, CaO:7.0-8.5, MgO:3.5-4.5, R
2O:14.0-15.0, CoO:0.006-0.01, Fe
2O
3: 0.3-0.5(R is a monovalent metallic ion).
The optimum weight per-cent of institute of the present invention blue heat-absorbing glass is: SiO
2: 70.45, Al
2O
3: 2.62, CaO:7.85, MgO:4.01, R
2O:14.89, CoO:0.0077-0.009, Fe
2O
3: 0.3-0.4.
It is as follows that blue heat-absorbing glass of the present invention has advantage: (1), production control are easy to, because adopted the cobalt oxide that is difficult for appraising at the current rate and the ferric oxide that color is not produced considerable influence that appraises at the current rate is that tinting material carries out composite coloration; (2), the product visible light transmissivity is big, the direct solar radiation transmitance is little, the sight line that makes glass neither hinder the people has good sunshading and heat-insulating effect again.This glass specific absorption is between the 399-465 nanometer, and the glass of 5 mm thick, visible light transmissivity are about 57%, and the solar radiation transmitance is about 43%, and performance all is better than white transparent glass and other colored glass.
Tinting material of the present invention is selected cobalt oxide powder (mixture of cobalt monoxide and cobalt sesquioxide, fineness is below 200 orders) and brown iron oxide (ferric oxide, fineness is below 200 orders) for use.In the cobalt oxide, amounting to metal content is 72%, in the brown iron oxide, and Fe
2O
3Content gets final product greater than 75%.
Below by embodiment the present invention is further described
To produce every 1000kg glass materials is example.
Embodiment 1
(1), raw material consumption (kg):
Silica sand 436, ground silica 308.8, rhombspar 164.4, Wingdale 29.5, fluorite 18 soda ash 231.9 saltcake 13.2 coal dusts 1.87 cobalt oxide powders 0.084, brown iron oxide 1.7.
(2), raw material in (1) is dropped into uniform mixing in the mixer, be input in the furnace hopper by the material of transfer roller again, enter in the melting furnaces by the roller charging machine with mixing, under 1480-1600 ℃ that material is molten for liquid, and adopt the glass horizontal agitator, guarantee uniform coloring; With the liquid material of uniform coloring by tin groove forming and annealing furnace after, carry through cutting again, packing promptly can be made into blue heat-absorbing glass finished product.
By embodiment 1 products obtained therefrom after testing with the optical property contrast of the antisolar glass of other color, referring to table 1, and other index all meets or exceeds national standard.The antisolar glass that uses this material side to produce, glass output can reduce about 3-5%, for the 85t/d side fired kiln, 30-50 ℃ of cooling end temperature decline.
Table 1
| The color of antisolar glass | Visible light transmissive is penetrated rate (%) | The direct transmissivity of sunlight (%) |
| Dark brown | ≥45 | ≤60 |
| Grey | ≥30 | ≤60 |
| Blue | ≥50 | ≤70 |
Embodiment 2
The raw material consumption is (kg):
Silica sand 477.3, ground silica 274.4, rhombspar 173.4, Wingdale 32.8, fluorite 20.3 soda ash 222.8 saltcake 17.5 coal dusts 2.43 cobalt oxide powders 0.098, brown iron oxide 1.25.
Production technique is with embodiment 1, and other optical property contrast is same as table 1.
In the production process of embodiment 1 and embodiment 2, cobalt oxide can expand into 1/20 concentration with rhombspar, Wingdale, ground silica, the soda ash done, comes into operation, and can increase the batching accuracy like this, particularly for the not high feed proportioning system of level of automation.Reductive agent powder and finings saltcake generally immobilize.
