Embodiment 1

[0022] 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 18-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,...

[0025] 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 18-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 50-station chain-type temperature-controlled curing machine ca...

Abstract

The invention relates to an electrostatic spraying process of a lampshade of an energy-saving lamp. The electrostatic spraying process includes the following steps that firstly, the lampshade is cleaned; then a lampshade glass shell is heated, the specific resistance is reduced, and electric conduction is carried out; then paint powder is sprayed to the inner wall of the lampshade; and finally thesprayed lampshade is heated, and the paint powder is cured into a film. By the adoption of the electrostatic spraying process, no harmful substance gas is exhausted in the production process, spraying is not limited by dead corners, and the sprayed material can be evenly distributed. The film, obtained after machining, on the inner wall of the lampshade has high anti-scraping strength, demoldingis not likely to happen when the energy-saving lampshade is packaged, discoloring or demolding is not caused when the energy-saving lamp works under the condition of conventional high and low temperature (170 DEG C), the film can be carbonized at the temperature of 300-350 DEG C, the glass shell can be conveniently washed and recycled, and no harmful gas is exhausted in the recycling process.

Description

technical field [0001] The invention relates to an electrostatic spraying process for an energy-saving lamp lampshade, which belongs to the technical field of spraying process. Background technique [0002] At present, most of the existing spraying methods for energy-saving lamp shades use solvent liquid coating, and the process is roughly as follows: first, the substances composed of the solvent liquid coating film are formulated, and then the ingredients composed of the 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 co...
