Embodiment 1

[0021] The electrostatic spraying process for lampshades of energy-saving lamps includes the following steps: firstly, cleaning the lampshades for subsequent spraying. Next, heat the glass bulb of the lampshade to reduce the specific resistance and conduct electricity. Specifically, the heating temperature of the lampshade glass bulb is set to 150°C. Subsequently, paint powder is sprayed on the inner wall of the lampshade. During this process, the spraying voltage is 50KV, and the machine speed is 6r / min. In order to make the spraying effect more stable, the electrostatic 16-station spray gun internal spraying machine can be used to spray the powder coating. Moreover, the powder suction airflow of the spray gun is 0.23Mpa, and the powder spray airflow is 0.18Mpa. At the same time, considering the uniform effect of spraying, the spray gun should be sprayed at least three times. Next, heat the sprayed lampshade to make the paint powder solidify and form a film. Specifically...

[0024] Electrostatic spraying process of energy-saving lamp lampshade: first, clean the lampshade. Next, heat the glass bulb of the lampshade to reduce the specific resistance and conduct electricity. Specifically, the heating temperature for the glass bulb of the lampshade is 400°C. Subsequently, paint powder is sprayed on the inner wall of the lampshade. During this process, the spraying voltage is 70KV, and the machine speed is 20r / min. In order to make the spraying effect more stable, the electrostatic 16-station spray gun internal spraying machine can be used to spray the powder coating. Moreover, the powder suction airflow of the spray gun is 0.28Mpa, and the powder spray airflow is 0.2Mpa. At the same time, considering the uniform effect of spraying, the spray gun should be sprayed at least three times. Finally, heat the sprayed lampshade to make the paint powder solidify and form a film. Specifically, a 48-station chain-type temperature-controlled curing machine c...

Abstract

The invention relates to an electrostatic painting process of an energy-saving lamp shade, comprising the following steps: firstly, cleaning a lamp shade; secondly, heating a glass shell of the lamp shade, lowering the specific resistance and conducting; thirdly, painting painting powder on the inner wall of the lamp shade; and finally heating the painted lamp shade so that the painting powder is solidified to form a film. After the electrostatic painting process is adopted, no harmful gas is discharged in the production process, the painting is not limited by a dead angle, and the painting material can be evenly distributed. A painting film obtained on the inner wall of the lamp shade after the lamp shade is processed has higher scratch strength, is not easy to demould in packaging the energy-saving lamp shade and does not change the color or demould when working at high and low temperature of 170 DEG C as usual; in addition, the painting film can be charred at 300-350 DEG C, the glass shell can be recovered conveniently and harmful gases can not be discharged in the recovery process.

Description

technical field [0001] The invention relates to a spraying process, in particular to an electrostatic spraying process for an energy-saving lamp shade. Background technique [0002] Most of the existing energy-saving lamp shades are sprayed by solvent solution coating, and the process is roughly as follows: firstly, the substances composed of solvent liquid coating film are batched, and then the components composed of solvent liquid coating film are fully mixed and mixed. Then the solution was sieved through a 300-mesh screen and stored in barrels. Then use the compressor airflow as the medium to implement the solvent solution coating film on the solution spraying machine to coat the inner surface of the cleaned glass lampshade. The last coated shade is dried into a film. In the production process of the film-forming technology of the solvent-based liquid-phase coating process, there are volatile and irritating odor components that are harmful to human health, which are ha...
