luminous production process

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 : red luminous : 55 grams decorative aggregate , 40 g of magnesium sulfate , lithium phosphate, 2 g , 3 g of copper nitrate blue luminous : 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 . Purple luminous powder : 63 g calcium sulfide , magnesium sulfate 26 g , 10 g sodium sulfide , strontium nitrate 1 g . Green luminous powder : 55 g calcium sulfide , potassium sulfide 1 g , 10 g sodium sulfide , barium nitrate 12 g , 13 g of indium nitrate . Luminous yellow : 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 , glow in the dark stone, 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 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 .
