For the blue heat-absorbing float glass, the transmissivity is large for visible light and small for direct radiation of the sun, for example of 5mm thickness said glass, about 57% for the visible light, and 43% for the direct radiation of the sun, the absorptivity is between 399-465 nm. The properties are all superior to the white transparent glass and other stained glass.

Description

A kind of blue heat-absorbing float glass
The invention belongs to a kind of prescription of colored glass.
Along with the raising day by day with living standards of the people of developing rapidly of industrial and agricultural production, building construction, particularly Development of High-rise Buildings are very rapid.Therefore, increasing to the demand of colored glass.The effect of colored glass mainly contains: A, when making the people see buildings from the outside, a kind of enjoyment of U.S. is arranged; B, good visible transmission value to be arranged, can reduce the heat that buildings absorbs from the outside again; C, sturdy and durable.
That colored glass at present commonly used mainly contains is dark brown, grey and covellite look glass.Dark brown darker with the smoked glass tone, give oppressiveness or sense of depression.Though covellite look glass tone is more lucid and more lively, thermal characteristics is poor, can not satisfy the needs of Highrise buildings.
The tinting material of above-mentioned three kinds of colored glass contains chemical elements such as selenium, nickel, copper respectively.On production technique, above-mentioned chemical element is very unstable in producing the glass process, appraises at the current rate easily and volatilization loss.In order to address this problem, to adopt usually under redox agent and the fusing atmosphere and control, thereby increased technology difficulty, and usually cause the misalignment of glass finished product in process of production.For the nickeliferous glass of tinting material, also there is the another one problem, promptly in most of the cases, the glass of wall or window will quench between work, because do not quench, glass is in case broken, can form elongated sharp glass fragment, cause serious casualty accident easily, after glass quenches, in case broken can be broken into the blunt fritter in edge, unlikelyly seriously hurt sb.'s feelings.Yet, if nickeliferous in the glass, can form the stone point, easily broken in quenching process, cause damage and waste, thereby increase the input cost of buildings.In prior art, people such as contriver Edward N Bao Leshi have declared a kind of non-nickle ion blue glass prescription.U.S. Patent number: 4866010, date of patent: 1989912.But the tinting material in this non-nickle ion blue glass prescription is Fe 2O 3, Co 3O 4And Se.Tinting material still contains selenium in its prescription in other words, belong to and contain selenium glass, and production technique is complicated.
Purpose of the present invention provides a kind of prescription that does not contain the blue heat-absorbing float glass of selenium (Se).
Blue heat-absorbing float glass, its prescription is made up of base-material and tinting material, and base-material comprises silica sand, ground silica, rhombspar, Wingdale, fluorite, soda ash, saltcake and coal dust, the major ingredient (percentages) that its finished product constitutes: SiO 267-71%, Al 2O 30.5-3%, CaO7-10%, MgO3.5-4.5%, R 2O14-16% (R is a monovalent metallic ion); Tinting material is cobalt oxide powder and brown iron oxide, wherein Fe 2O 30.1-0.7%, CoO0.003-0.025%.
The best composition that prescription constitutes: SiO 269.87%, Al 2O 32.17%, CaO7.90%, MgO3.99%, R 2O14.89%, Fe 2O 30.31%, CoO0.015.
Owing to do not contain selenium (Se) in the prescription of blue heat-absorbing float glass of the present invention, therefore simplified technology, and made constant product quality, its production method is as follows:
One, with raw material silica sand, ground silica, rhombspar, Wingdale, fluorite, soda ash, saltcake, coal dust and tinting material cobalt oxide powder, brown iron oxide, proportioning drops in the mixer on request, full and uniform mixing;
Two, with the mass transport of mixing in furnace hopper, be sent in the melting furnaces by the roller charging machine, under 1480-1600 ℃, material is molten for liquid, the material that will melt again for liquid state passes through tin groove forming, after the annealing furnace annealing, is the blue heat-absorbing float glass finished product.
Tinting material of the present invention selects for use oxygen than cobalt powder (mixture of cobalt monoxide and cobalt sesquioxide, fineness is below 200 orders) and brown iron oxide (ferric oxide, fineness is below 200 orders).In the cobalt oxide, amounting to metal content is about 72%, in the brown iron oxide, and Fe 2O 3Content is greater than 75%.
The invention will be further described below by embodiment.
Embodiment 1
To produce 1000Kg glass materials is example, raw material consumption (Kg): silica sand 376, ground silica 370.7, rhombspar 180.3, Wingdale 31.4, soda ash 216.1, saltcake 19.7, coal dust 2.04, tinting material brown iron oxide 1.777, cobalt oxide powder 0.1639.
Above-mentioned raw materials is dropped into uniform mixing in the mixer, by transfer roller the material that mixes is input in the furnace hopper again, send in the melting furnaces by the roller charging machine, under 1480-1600 ℃ that material is molten for liquid, and adopt the glass horizontal agitator, to guarantee uniform coloring, liquid material with uniform coloring passes through tin groove forming then, after annealing furnace annealing, cut, packing gets final product again.
Embodiment 2
To produce 1000Kg frit consumption (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 dust 2.43, cobalt oxide powder 0.098, brown iron oxide 1.25.Its production technique is with embodiment 1.
In the production process of embodiment 1 and embodiment 2, in order to increase the accuracy of batching, cobalt oxide and rhombspar, ground silica, the soda ash done can be expand into 1/20 concentration, come into operation, though blue heat-absorbing float glass of the present invention, tinting material is neither nickeliferous in prescription, does not contain selenium (Se) again, only selects Fe for use 2O 3And cobalt oxide, but still can make glass reach a kind of very ideal blueness.The people who is familiar with the glass specialty knows, make stained glass, in the stained glass prescription, subtract certain tinting material or replace another kind of tinting material, or change tinting material consumption, proportioning with a kind of tinting material, not only influence the color of glass, and influence the optical transmittance and the texture quality of glass.The target that we draft is to produce a kind of very desirablely aspect aesthetic, and optical transmittance is good, and robust blue glass, and production technique is made every effort to simply, the blue glass uniform hue of producing.By this target, we have descended the time on other oxide content, proportioning and the simplification technology of tinting material, tinting material and glass.This is an arduous process of the test, has failed, and test is carried out repeatedly again, and through more than 2 years, blue heat-absorbing float glass prescription of the present invention has been studied successfully in up to a hundred tests finally.With the blue heat-absorbing float glass that this prescription is produced, visible light transmissivity is big, and the direct solar radiation transmitance is little, and 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.Particularly tinting material has selected for use the cobalt oxide that is difficult for appraising at the current rate color not to be produced the ferric oxide of considerable influence with appraising at the current rate in prescription, and the selenium of need not easily appraise at the current rate (back of appraising at the current rate is big to the color influence) is simplified technology.Blue heat-absorbing float glass prescription of the present invention has been stood test in extensive, repeatability in producing, and the quality product height receives praises from customers, and product has been obtained the coml immense success, and economic and social benefit is very remarkable.
