In order to overcome the shortcoming of above-mentioned prior art, the object of the present invention is to provide the detection method of organic substance residues amount in a kind of fluorescent powder paste material, effectively can carry out the detection that in fluorescent powder paste material, organic substance residues amount is how many, thus solve fluorescent powder and be made into slurry and make the problem that after fluorescent light, light efficiency is low, light decay is large, extend the serviceable life of fluorescent light, ensure that product quality.
In order to achieve the above object, the technical scheme that the present invention takes is: the detection method of organic substance residues amount in a kind of fluorescent powder paste material, and step is as follows:
Step 1: be that alumina solution, the pure water of 1-5% carries out mixing and stirring according to mass ratio 1:3:4 with fluorescent powder by mass concentration, stirring rate is 800-900 rev/min, and mixing time is 3-4h;
Step 2: configuration quality concentration is polyoxyethylene (PEO) solution of 5-10%, solution quality be the 4-5 of alumina solution quality doubly, joining in step 1 gained potpourri and to stir, stirring rate is 200-400 rev/min, mixing time 2-3h, is made into organic ink;
Step 3: take organic ink 40g and be placed in 50ml ceramic crucible and carry out roasting, temperature is 150 DEG C, and the time is 10 minutes, and then carries out 600 DEG C of roastings, and the time is 30 minutes.
Step 4: after being cooled to room temperature 25 DEG C, utilizes UV-2501 double-beam spectrophotometer to carry out the test of slurry powder reflections rate, and the slurry after roasting is carried out to the contrast test of powder body colour.
The detection method of organic substance residues amount in a kind of fluorescent powder paste material that the present invention adopts, UV-2501 double-beam spectrophotometer is utilized to carry out the test of slurry powder reflections rate, by carrying out the contrast test of powder body colour to the slurry after roasting, can judge slurry used in the fluorescent light manufacturing process power to Adsorption of Organic performance, according to the size of slurry powder reflections rate, judge the number of organic substance residues amount in its slurry, thus solve fluorescent powder be made into slurry make fluorescent light after light efficiency low, the problem that light decay is large, extend the serviceable life of fluorescent light, ensure that product quality.
