Photoluminescent Rigid Sheet What luminous powder production process

Luminous powder luminous powder is usually divided into two types of light-induced luminous and storage of radioactive. After light-induced energy storage luminous phosphors by Photoluminescent Rigid Sheet‍ natural light, fluorescent light, ultraviolet light and other radiation, the energy stored in the stop light irradiation, the fluorescence way slowly released, so at night or darkness , can still see the light, lasted for several hours to ten hours. With radioactive luminous powder, is mixed with radioactive materials in the phosphor, the use of radiation emitted by radioactive substances continue to excite phosphors glow, luminous light-emitting such a long time, but little environmental pollution and toxic and hazardous applications.

   Luminous powder production process:

I. Features: Unlike the luminous phosphors, which non-radioactive, light long short but luminous efficiency, low cost, colorful.

Second, the equipment: electric furnace, crucible, ball mill, drying equipment.

Third, the formula:

A red luminous powder: 55 g of barium sulfate, Photoluminescent Aluminum Sheet‍ 40 g of magnesium sulfate, lithium phosphate, 2 g, 3 g of copper nitrate

Two blue luminous powder: 63 g of calcium sulfide, sodium sulfate 5 g, 5 g of potassium sulfate, strontium sulfate, 10 g, 6 g of sodium chloride, 1 g of silver nitrate, 10 g magnesium sulfate.

3 purple luminous powder: 63 g calcium sulfide, magnesium sulfate 26 g, 10 g sodium sulfide, strontium nitrate 1 g.

4 green luminous powder: 55 g calcium sulfide, potassium sulfide 1 g, 10 g sodium sulfide, barium nitrate 12 g, 13 g of indium nitrate.

5 yellow luminous powder: 55 g barium sulfide, magnesium sulfate 40 g, 2 g aluminum sulfide, potassium nitrate 3 g.

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, mix the raw materials directly on the burning furnace, the temperature is 133 degrees, burning 50 minutes After hand-colored pick insufficiency 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 Photoluminescent Masterbatch‍ can be placed in the drying oven.

Fifth, use: put a colorless transparent plexiglass Two bananas dissolved in water. After adding 72 hours to the amount of luminous paint on watches, clocks, instruments and crafts.‍
