What are the methods for removing old paint?
1 Answers
Methods for removing old paint from cars include sandblasting, manual paint removal, mechanical paint removal, chemical paint removal, electric grinding, and flame scraping. Among these, manual paint removal, mechanical paint removal, and chemical paint removal are more commonly used. More related information is as follows: 1. Chemical paint removal involves using paint strippers to remove old paint films. Commonly used strippers in the past were T-1 and T-2. T-1 stripper is a milky paste-like liquid composed of ketone, alcohol, benzene, and ester solvents mixed with an appropriate amount of wax, primarily used to remove old paint films of oil-based paint, ester gum paint, and phenolic paint. T-2 stripper is a mixture of ketone, alcohol, ester, and benzene solvents, with stronger paint film swelling ability and faster removal speed than T-1, mainly used to remove old paint films of oil-based paint, alkyd paint, and nitro paint. 2. Manual paint removal is a common method in painting work and the only method for partially removing old paint films. It mainly relies on tools such as scrapers, knives, wire brushes, and sandpaper to remove old paint from the surface of car body components. This method is simple but labor-intensive and inefficient. 3. Mechanical paint removal uses electric or pneumatic tools, such as wire wheels, wire grinders, and dry/wet sandpaper grinders, to replace manual scraping and grinding. This method not only improves work efficiency but also reduces labor intensity, making it a widely used paint removal method in the car body repair industry.
