Abstract

The present invention relates to glass producing technology and the coloring agent includes Fe2O3 in 0.03-0.7wt% of glass, Cr2O3 0.02-0.3 and Nd2O3 0.02-2. Jadeite green glass produced by using the coloring agent has the characteristics of:visible light transmissivity 51-55%, sunlight transmittance 57.2% and main wavelength 492-495nm. Using the coloring agent needs no addition of oxidant as coloring promoter and this can prevent corrosion of kiln by strong oxidant and reduce the exhausted NOx. In addition, the mixed Fe-Cr-Nd coloring agent system is ever stable compared with conventional jadeite green coloring agent system.

Description

Copper-free jadeite green coloring agent for float process glass
The invention belongs to the glass production method, relate generally to a kind of copper-free jadeite green coloring agent for float process glass.
At present, the copper coloring system is all adopted in the production of emerald green float glass.For guaranteeing emerald green special colour, need to guarantee copper in glass with a large amount of Cu 2+Form exists.Because there is following running balance: Cu in copper in glass 2+=Cu +, Cu +Do not develop the color Cu 2+Be blue, when ambiance was the state of oxidation, balance moved to the left side, Cu 2+Content will increase.For satisfying this condition, must in admixtion, add NaNO 3And so on strong oxidizer, it is serious that its result causes Dayao to corrode, and shortens kiln age significantly.The discharging of NOX has simultaneously also aggravated the pollution of environment.In addition, owing to well-known reason, for guaranteeing that floating to throw medium not oxidized, adopted restitutive protection's gas in the moulding molten tin bath, this just and Cu 2+The well-oxygenated environment that requires conflicts, and is bigger to molten tin bath harm in the production.
The objective of the invention is to propose a kind of tinting material of emerald green glass, make it can solve technical problem in fusing and the moulding, the protection molten tin bath makes it can reduce the cost of making this glass types simultaneously.
The essential characteristic of Na-Ca-Si sheet glass is to form (to account for the weight percent meter of glass gross weight) by following basic ingredient
SiO 2 65～75％
Na 2O+K 2O 10～20％　
CaO 5～16％
MgO 2～7％
Al 2O 3 0～5％
The composition of parent glass is not crucial to the present invention, and Na-Ca-Si sheet glass that can be common is formed, this parent glass is that those skilled in that art are in common knowledge, is to produce in the continuous melting stove, and forms sheet glass by floating process.
The component and the amount ranges thereof that add tinting material of the present invention in above-mentioned parent glass component are:
Tinting material component and consumption (accounting for the weight percent of glass summary table)
Fe 2O 3： 0.03～0.7
Cr 2O 3： 0.02～0.3
Nd 2O 3： 0.02～2
In the tinting material component, Nd 2O 3Adding have a very important role Nd to guaranteeing emerald green peculiar tone 3+There is stronger absorption at 574nm and 742nm, has Cu 2+At the similar absorption peak in 700nm-780nm place.Therefore, Nd 3+Existence can reach desired spectral hue.
In above component, Fe 2O 3In glass, there is part Fe 2+With Cu 2+Absorption peak very approaching, produce similar spectral response curve, but the too much adding of iron causes the glass metal heat absorption to increase, the fusing difficulty strengthens.For remedying the deficiency of tone, tinting material of the present invention has been introduced Nd 2O 3, therefore, can produce satisfied jadite glass by the mixing of above-mentioned tinting material is painted.
Utilize the emerald green glass of tinting material production provided by the invention to have following characteristic:
As seen light permeable rate: 51～55%
Sunlight projection ratio: 57.2
Predominant wavelength: 492-495nm
Adopt tinting material provided by the invention to form not need and in batching, add any oxygenant of impelling tinting material painted of being used to, can avoid the erosion of strong oxidizer to Dayao, simultaneously, reduced the discharging of NOX, owing to adopt Fe-Cr-Nd mixing coloring system, painted more stable than former emerald green Cu-Cr coloring system, can prolong kiln age significantly, save manufacturing cost.
In the present invention, the tinting material that adds in glass is formed is the form with oxide compound, but does not get rid of other form.As the one skilled in the art in other form of knowing except that oxide compound, as element form, also can be used in the batching composition, but in batching fusion and treating process, it will transform into the oxide form of the disclosed scope of the present invention, be similarly feature of the present invention and contain.
Embodiment:
In following parent glass (to account for the weight percent meter of glass gross weight)
SiO 2 71.3
Na 2O 14.7
CaO 8.6
MgO 4.4
Al 2O 3 1.0
It is as follows to add the given tinting material of the present invention: (accounting for the weight percentage of glass summary table)
Fe 2O 3 0.69％
Cr 2O 3 0.06％
Nd 2O 3 1％
Through evenly stirring and high temperature melting just can obtain pure jadite float glass, its visible light transmissivity: 54%; Sunlight projection ratio: 57.2%; Predominant wavelength: 492nm.
