Embodiment 1

[0015] First, clean the lampshade 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. And, the powder suction airflow of the spray gun is 0.23Mpa, and the powder injection 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, a 48-station chain-type temperature-controlled curing machine can be used to cure the coating powder to form...

Embodiment 2

[0017] 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. And, the powder suction airflow of the spray gun is 0.28Mpa, and the powder injection 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 can be used to cure the coating powder to form a film, and the tem...

Embodiment 3

[0019] First, clean the lampshade 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 15r / 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. And, the powder suction airflow of the spray gun is 0.26Mpa, and the powder injection airflow is 0.2Mpa. 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, a 48-station chain-type temperature-controlled curing machine can be used to cure the coating powder to for...

Abstract

The invention relates to a spraying technology, in particular to an energy saving lamp lampshade electrostatic spraying technology, which comprises the following steps of cleaning a lampshade; heating a lampshade glass bulb, reducing specific resistance, and conducting; spraying coating powder on the inner wall of the lampshade; finally heating the sprayed lampshade, and curing and film-forming the coating powder. According to the spraying technology, no harmful substance gas is discharged in the production process, the spraying cannot be limited by dead angles, and the sprayed materials can be uniformly distributed. A coating film of the inner wall of the lampshade obtained after processing has higher scraping resistance strength, is not easy to strip when being used for packaging the energy-saving lampshade, is not easy to discolor or strip when working under the condition of conventional high low temperature (170 DEG C), and can be carbonized at the temperature of 300-350 DEG C, so that the glass bulb can be conveniently cleaned and recycled, and harmful gas cannot be discharged in the recycle process.

Description

technical field [0001] The invention relates to a spraying technology, in particular to an electrostatic spraying process for an energy-saving lamp shade. It belongs to the field of spraying technology. 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 formulated, 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 irritating odor groups...
