Fluorescent powder dispersion method
A fluorescent powder, dispersion technology, applied in the direction of chemical instruments and methods, luminescent materials, etc., can solve the problems of unfavorable phosphor powder manufacturing cycle and brightness, long, 18 to 40 hours, lengthening phosphor powder manufacturing cycle, etc., to achieve dispersion time The effect of shortening, small decrease in brightness, and increase in brightness

Embodiment 1
[0008] Example 1: First, the phosphor, water and dispersed balls are mixed in a mass ratio of 1:1.2:0.8. The dispersed balls are cylindrical nylon balls with a diameter of 2 to 3 mm and a height of 2 to 3 mm, and then mix them in the mixture Add 1.786ml of potassium silicate solution with a mass concentration of 28% per kilogram of phosphor; then use a disperser with a speed of 400 to 600 revolutions / min to disperse for 2 to 7 hours. After the dispersion is completed, remove the dispersion ball and use the reducer The pressure conveying method separates the phosphor powder slurry; finally, the separated phosphor powder slurry is dehydrated, which is the dispersed green luminescent phosphor.
Embodiment 2
[0009] Example 2: First, the phosphor, water and dispersed balls are mixed in a mass ratio of 1:1.2:0.8. The dispersed balls are cylindrical nylon balls with a diameter of 2 to 3 mm and a height of 2 to 3 mm, and then mix them in the mixture Add 3ml of potassium silicate solution with a mass concentration of 24% per kilogram of phosphor; then use a disperser with a speed of 400 to 600 revolutions per minute to disperse for 2 to 7 hours. After the dispersion is completed, remove the dispersion ball and apply a reduced pressure The conveying method separates the phosphor powder slurry; finally, the separated phosphor powder slurry is dehydrated, which is the dispersed green luminescent phosphor.
Embodiment 3
[0010] Example 3: First, the phosphor, water and dispersed balls are mixed in a mass ratio of 1:1.2:0.8. The dispersed balls are cylindrical nylon balls with a diameter of 2 to 3 mm and a height of 2 to 3 mm, and then mix them in the mixture Add 5ml of potassium silicate solution with a mass concentration of 22% per kilogram of phosphor; then use a disperser with a speed of 400 to 600 revolutions / min to disperse for 2 to 7 hours. After the dispersion is completed, remove the dispersion ball and use a reduced pressure The conveying method separates the phosphor powder slurry; finally, the separated phosphor powder slurry is dehydrated, which is the dispersed green luminescent phosphor.
