Phosphor production process

glow in the dark powder

I. Features: This is different from the luminous phosphors, which non-radioactive, light long short but luminous efficiency, low cost, colorful. Second, the device: furnace, crucible, ball mill, drying equipment. Third, the formula: red luminous: barium sulfate 55 g, 40 g of magnesium sulfate, lithium phosphate 2 g, 3 g of copper nitrate luminous blue: 63 g calcium sulfide, sodium 5 g, 5 g of potassium sulfate, strontium sulfate 10 grams, 6 grams of sodium chloride, 1 g of silver nitrate, magnesium sulfate 10 g. Purple luminous: 63 g calcium sulfide, magnesium sulfide 26 grams, 10 grams of sodium sulfide, strontium nitrate 1 g. Green luminous: 55 g calcium sulfide, potassium sulfide 1 g, 10 g of sodium sulfide, barium nitrate, 12 grams, 13 grams of indium nitrate. Yellow luminous: barium sulfide 55 g, 40 g magnesium sulfate, aluminum sulfide 2 g, 3 g of potassium nitrate. Fourth, Crafts: after with a good raw material, the temperature on the crucible furnace heating, raw material in the pot, but also do not pan directly after mixing the raw material on the furnace to burn at a temperature of 133 degrees, 50 minutes to burn after hand-pick incomplete color impurities, and then placed in the cooked raw mill ground into fine powder and then soaked in water for precipitation to remove water, the sink in the powder can be placed in the oven to dry. Fifth, use: the colorless transparent plexiglass dissolved in two parts of a banana water. 72 hours after adding an appropriate amount can be applied to the luminous watches, clocks, instruments and crafts.
