Abstract
A colorless transparent glass with the function of shielding ultraviolet radiation features use of SiO2 as main raw material, CeO2 as ultraviolet shielding material (0.3-0.6 wt.%), and ErO as decoloring agent (0.02-0.07 wt.%). Its advantages are low cost and high radiation shielding power.
Description
Technical field
The present invention relates to a kind of colourless transparent glass, relate in particular to a kind of colourless transparent glass with ultraviolet radiation preventing function.
Background technology
With regard to Glass Containers use aspect, wish that always Glass Containers can either cover ultraviolet ray to prevent that material is rotten in the container, can clearly recognize the form of material in the container again.That is to say that Glass Containers should water white transparency, again can ultraviolet radiation preventing.Generally, the content of Glass Containers can produce rotten, variable color, spoiled phenomenon under ultraviolet radiation, is the principal element that causes above-mentioned reason and its medium wavelength is ultraviolet ray about 320nm.
At present, have the relevant glass that is applicable to this kind purposes of report in the pertinent literature abroad.From disclosed content, it is to add cerium dioxide (CeO in common soda-lime-silica glass
2), content is controlled between 0.2 to 0.5 weight percent.Though cerium dioxide can have the absorption action of ultraviolet ray,, can make the glass that adds cerium dioxide be faint yellow because of its tint permanence.Therefore, also need to add discoloring agent usually.Disclose in this piece of writing report, as discoloring agent, content is the 0.2-0.5 weight percent Neodymium trioxide.
Because Neodymium trioxide itself has livid purple look, can neutralize mutually with yellowish cerium dioxide, it is colourless that glass is approached, thereby make glass reach transparent effect.But the Neodymium trioxide price is very high, and addition is difficult to grasp and control.Cross that I haven't seen you for ages makes glass be yellow or yellow-green colour, cross and to make glass be cyan at most.
Summary of the invention
Therefore, purpose of the present invention just is to provide a kind of colourless glass with anti-ultraviolet function that approaches of cheapness.
The contriver finds that in experiment Erbium trioxide itself is rose pink, can neutralize with the faint yellow of cerium dioxide equally, and it is colourless that glass is trended towards.The price of Erbium trioxide is low than Neodymium trioxide, and its chromophoric characteristic is extremely stable, is not subjected to the influence of oxygenants such as environment and cerium dioxide, becomes more readily available desirable effect.
Therefore, according to above-mentioned purpose of the present invention, colourless transparent glass with anti-ultraviolet function provided by the invention, with silicon-dioxide is main raw material, as the ultraviolet radiation preventing raw material, it is characterized in that with cerium dioxide the content of described cerium dioxide is between 0.3 to 0.6 weight percent, as discoloring agent, its content is between the 0.02-0.07 weight percent with Erbium trioxide.
Embodiment
To specifically describe preferred embodiment of the present invention below.
The contriver determines the content of cerium dioxide and the selection and the content of discoloring agent through repeatedly experiment.Finally be defined as, as the raw material employing cerium dioxide of ultraviolet radiation preventing effect, content is controlled at (table one shows the relation of cerium dioxide containing ratio and absorption of UV) between 0.3 to 0.6 weight percent.Discoloring agent is selected Erbium trioxide for use, and content is controlled at 0.02 between 0.07 weight percent.Table two shows parameter in above-mentioned scope and more borderline examples.Test sample has been carried out three desired values to be measured.The thickness of glass of each test sample is 10mm.In the industry, more than 85%, predominant wavelength is in the 565-575nm scope as the transparency in these three desired values, and index purity basically can judge then that below 1.5% this glass belongs to the high-quality colourless transparent glass.Then ideal in the 568-572nm scope as predominant wavelength.As can be seen, added Erbium trioxide each example as discoloring agent from table two, three desired values of its test sample all in optimal scope, can be judged as the high-quality colourless transparent glass in view of the above.And through visual inspection, each example all has better water white transparency performance to comparative example in the table two.
Table one
Table two

In the superincumbent example, the iron oxide content in the glass can also be controlled under 0.05 weight percent.Because the iron of the cerium dioxide that adds in can glass is had an effect, and makes the iron oxidation, and viridant ferrous ion is tailed off, it is many that yellowy ferric ion becomes.Therefore, transparent refined Y will significantly increase, and predominant wavelength is to the conversion of wavelength side, and the color of glass has yellow.The content of ferric oxide is controlled at below 0.05 weight percent, just can be controlled at the yellow of glass or yellow-green colour in the minimum extent.Technically, be controlled at the content of ferric oxide under 0.05 weight percent not difficult.
Claims (2)
1, a kind of colourless transparent glass with ultraviolet radiation preventing function, with silicon-dioxide is main raw material, with cerium dioxide as the ultraviolet radiation preventing raw material, it is characterized in that, the content of described cerium dioxide is between 0.3 to 0.6 weight percent, as discoloring agent, its content is between the 0.02-0.07 weight percent with Erbium trioxide.
2. colourless transparent glass as claimed in claim 1 is characterized in that, also comprises ferric oxide, and content is below 0.05 weight percent.
