Description
Technical field
The present invention relates to a kind of pick-up unit, particularly relate to a kind of pick-up unit of float glass lower surface stannize amount.
Background technology
The tin element that float glass infiltrates forms under reducing atmosphere, and the tin element that therefore infiltrates lower glass surface mainly is a Bivalent Tin.Under oxidizing atmosphere during converted products,, the glass surface quality produced have a strong impact on because Bivalent Tin can be converted into tetravalent tin.At present, Chang Yong tin element quantitative detecting method comprises spectrophotometric method, polarography, atomic absorption method and and chemical analysis.These method complicated operations generally need the auxiliary of chemical corrosion or dissolving method, and analytical cycle are longer.Add that when adopting said method to analyze owing to need to be exposed in the air of oxidizing atmosphere in the sample analysis process, destroyed the original valence state of tin element in glass, errors of analytical results is bigger.Another kind of effectively tin element quantitative detecting method is an x ray fluorescence spectrometry, yet, this method can not be distinguished the valence state of the tin element that infiltrates in the glass, and, also can't in glass industry, realize on-line continuous detection by quantitative to the float glass lower surface tin element owing to adopt the X ray light pipe as radiation source.In addition, existing a kind of Ultraluminescence lamp of differentiating float glass lower surface, its principle is to utilize Ultraluminescence effect difference float glass upper and lower surface, but is not the tin element valence state that infiltrated of quantitative test float glass lower surface and the technology and the method for content.
Summary of the invention
Can't distinguish the tin element valence state, also can't realize carrying out the deficiency of online detection by quantitative in order to overcome existing tin element quantitative detecting method, the invention provides a kind of device with detecting doping tin content of float glass lower surface using ultraviolet fluorescence testing, this method not only can realize the detection by quantitative to float glass surface tin element, and can carry out continuous on-line to float glass surface tin element content and detect.
The technical solution adopted for the present invention to solve the technical problems is: ultraviolet light source and monochromator at one end are set, can produce the ultraviolet ray of fixed wave length; Place beam path alignment device, ultraviolet ray/visible light receiving trap, signal amplifying apparatus, signal digital conversion and record and display device at the other end, and be furnished with precision voltage source and caliberating device.The ultraviolet ray that the ultraviolet light source emission wavelength is certain shines float glass lower surface through monochromator.The tin element that penetrates into float glass lower surface is ultraviolet ray excited following, produce the photoluminescence phenomenon, be energized into high energy and unsettled excited state by stable ground state, outwards emission and the corresponding characteristic wavelength fluorescent photon of tin element valence state in the process that falls back to ground state by excited state.The content of float glass lower surface Bivalent Tin element is many more, and the photon numbers of the Bivalent Tin elemental characteristic wavelength that is produced by the photoluminescence effect is many more.Within the specific limits, characteristic wavelength fluorescence intensity and the linear corresponding relation of Bivalent Tin content that produces by the photoluminescence effect.At this moment in suitable direction the photon receiving trap being set, through conversion of signals and amplifying circuit, is horizontal ordinate with the wavelength, is ordinate with the fluorescence intensity, writes down in microcomputer and shows.According to the working curve of prior foundation, utilize analysis software just can obtain the content of the Bivalent Tin element of float glass lower surface.Tin element is short to the ultraviolet response time, and this method does not have dimensional requirement to sample, also need not process in advance, therefore, utilize this method to make things convenient for and realize accurately online or off-line detection by quantitative to the Bivalent Tin element of float glass lower surface.
The invention has the beneficial effects as follows: the content that can accurately detect the Bivalent Tin element of float glass lower surface, but also can realize online easily or offline inspection, according to testing result, and then can adjust the production status condition in real time, keep or reduction float glass lower surface stannize amount, guarantee to produce the high-quality float glass product that can be used for deep processing.
