(3) the resuspended above-mentioned post precipitation of water leaves standstill, and abandoning supernatant must precipitate again; This step is carried out 0 ~ 10 time, with the fluorescent material that is tentatively cleaned;
(4) fluorescent material of the resuspended above-mentioned preliminary cleaning of water gets fluorescent material suspension liquid two;
(5) in above-mentioned fluorescent material suspension liquid two, add density less than 1g/cm
3Organic reagent, leave standstill separatory after stirring, discard supernatant liquid behind the separatory, gained lower floor liquid is the fluorescent material that cleans up.
In a preferred embodiment of the invention, the weight percent of the fluorescent material that is polluted by the polymer organic binder bond in described fluorescent material suspension liquid one in the described step (1) is 10 ~ 80%.
In a preferred embodiment of the invention, organic washing agent in the described step (2) is that concentration is the aqueous solution or the commercially available washing liquid of 1% Alconox powdery precise cleaning agent, the amount of adding be step (1) gained fluorescent material suspension liquid one volume 0.5 ~ 2%; Churning time is 1.5 ~ 3 hours.
In a preferred embodiment of the invention, the organic reagent in the described step (5) comprises whiteruss and hexane, its add-on be fluorescent material suspension liquid two volume 1.5 ~ 3%; Churning time is 5 ~ 20 minutes, and leaving standstill the separatory time is 5 ~ 20 minutes.
In a preferred embodiment of the invention, described water is deionized water.
The invention has the beneficial effects as follows:
1, the present invention can clean the fluorescent material that is polluted by the polymer organic binder bond level to qualified fluorescent material, makes that the material that originally will go out of use is regenerated, and has avoided waste, has reduced production cost;
2, the selected reagent of treatment process of the present invention is cheap, obtains easily, and step process is simple, is fit to heavy industrialization and uses.
Embodiment
Below by embodiment technical scheme of the present invention is further detailed and describes.
(1) in the fluorescent material that xanchromatic is polluted by the polymer organic binder bond, adds deionized water, stir, get fluorescent material suspension liquid one; The weight percent of fluorescent material in described fluorescent material suspension liquid one that the polymer organic binder bond that wherein said quilt does not decompose fully pollutes is 10 ~ 80%;
(2) in above-mentioned fluorescent material suspension liquid one, add the aqueous solution or the commercially available washing liquid that concentration is 1% Alconox powdery precise cleaning agent, the amount that adds be step (1) gained fluorescent material suspension liquid one volume 1%, stir and staticly settle after 2 hours, abandoning supernatant must precipitate;
(3) leave standstill with the resuspended above-mentioned post precipitation of deionized water, abandoning supernatant must precipitate again; This step is carried out 5 times, with the fluorescent material that is tentatively cleaned; The polymer organic binder bond that the fluorescent material that should tentatively clean has been removed the yellow strain thing and do not decomposed fully, but wherein still contain carbon granules and other fine particle impurity;
(4) with the fluorescent material of the resuspended above-mentioned preliminary cleaning of deionized water, get fluorescent material suspension liquid two, and place separating funnel;
(5) in above-mentioned fluorescent material suspension liquid two, add density less than 1g/cm
