Abstract
The invention discloses a plastic shell depainting process. The plastic shell depainting process comprises the following steps: step 1, adding a depainting agent into a container, and soaking to-be-depainted plastic shells in the container for 3-8 hours; step 2, taking the plastic shells out of the container; step 3, soaking the taken-out plastic shells in fresh water for 1-3 hours; step 4, removing residual paint dregs by using a tool; and cleaning the plastic shells by using a brush; step 5, arranging the plastic shells on a meshed tray one by one; and step 6, baking the meshed tray in an oven for 20-40 minutes. The plastic shell depainting process disclosed by the invention can be used for completely removing paint from a plastic product and also farthest reducing damages to the plastic shells; and moreover, the product can be repainted, so that scrapping of the plastic shells can be greatly reduced, and the product yield rate can be effectively increased. The plastic shell depainting process disclosed by the invention is simple and environment-friendly.
