[0002] In the production process of the electrodeless lamp, the inner surface of the bulb is coated with fluorescent powder. The existing method is: first pickle the bulb with hydrofluoric acid or hydrochloric acid, and then dry it with an oven after washing with a large amount of ionized water. Liquid fluorescent powder is applied to the inner surface of the bubble, and then baked in a 600-degree oven for 35 minutes before it can be used. Some water coating or alcohol powder coating process is 10g / 1 lamp, which not only wastes a lot of energy, manpower and material resources, but also pollutes the environment very much, and the quality of the lamp is average.

Embodiment Construction
[0018] Such as figure 1 , figure 2 , image 3 with Figure 4 As shown, a special powder bucket for electrostatic spraying equipment includes a powder outlet 1 , a cover 2 , a powder bucket 3 , and a stirring blade 4 . The bottom of the powder bucket 3 is made of high-density microporous plate, and the mixing system of the powder bucket uses three layers of stirring blades 4. The S-shaped blades in the opposite direction stir symmetrically, and the powder outlet 1 is installed at the height of the middle blade. An electrodeless bulb shell electrostatic powder coating process is to mix the electrodeless lamp fluorescent powder and solid high-temperature curing agent evenly, then use special equipment to process the mixed powder to the required particle size, and then put the mixed powder into the special powder bucket of the electrostatic spraying equipment The principle of high-voltage electrostatic powder spraying is used to evenly coat the powder inside the bulb, and the...

The invention relates to an electrostatic powder coating process for an electrodeless light bulb shell, which is characterized in that: the fluorescent powder of the electrodeless lamp is mixed evenly with a solid high-temperature curing agent, and then the mixed powder is processed to the required particle size by special equipment, and then the mixed powder is placed Go to the special powder bucket of electrostatic spraying equipment and use the principle of high-voltage electrostatic powder spraying to evenly coat the powder inside the bulb, and then cure the powder-coated bulb through the normal sealing and exhaust process. Its advantages are: it not only improves the luminous efficiency of the non-comparable lamp, but also the electrostatic powder coating can directly apply powder, the process is simple, the powder is saved, the cost is reduced, and it has the functions of energy saving and environmental protection.
Description
technical field [0001] The invention relates to a spraying process for uniformly and firmly coating solid three-color fluorescent powder on the inner surface of an electrodeless bulb shell, in particular to an electrostatic powder coating process for an electrodeless bulb shell. Background technique [0002] In the production process of the electrodeless lamp, the inner surface of the bulb is coated with fluorescent powder. The existing method is: first pickle the bulb with hydrofluoric acid or hydrochloric acid, and then dry it with an oven after washing with a large amount of ionized water. Liquid fluorescent powder is applied to the inner surface of the bubble, and then baked in a 600-degree oven for 35 minutes before it can be used. Some water coating or alcohol powder coating process is 10g / 1 lamp, which not only wastes a lot of energy, manpower, and material resources, but also pollutes the environment greatly, and the quality of the lamp is average.
