Abstract

The invention discloses a plastic housing depainting technology. The plastic housing depainting technology comprises the following steps: step one: adding a paint stripper into a container, placing aplastic housing to be depainted in the container and soaking for 3-8 hours; step two: taking out the plastic housing from the container; step three: placing the taken plastic housing in a clear watertank and soaking for 1-3 hours; step four: removing a residual paint slag by using a tool, and cleaning the plastic housing by using a hair brush; step five: placing the plastic housings on a net plate one by one; and step six: placing the net plate in an oven and baking for 20-40 minutes. The plastic housing depainting technology is capable of completely removing paint of a plastic product, reducing damage to the plastic housing in the greatest extent, and re-spraying the product, thereby greatly reducing scrappage of the plastic housing, and effectively improving a product yield. The plastichousing depainting technology is simple and environment-friendly.
