Many factors affect the quality of the thermal spray coating, spray coating and melt the categories. Practice has proved that as long as the strict implementation of process rules, pay attention to the following technical factors, the coating quality can be guaranteed. (1) of the workpiece surface preparation ① undercut undercut means to provide a space to accommodate the thermal sprayed layer on the base material or part or worn out vehicle size. When the shaft is not usually wear, but to save labor and materials can be divided into steps undercut, shaft head indeed manner. ② clear up that remove oil, rust, paint, so that the surface is clean. CTC degreasing better, not on the part under the residual film, but harmful carbon tetrachloride, the operation should be cautious. Flame baking oil suitable for porous castings cleanup South China Sea metal spraying, including Jiangsu metal spraying, oxygen-acetylene flame baking oil most commonly used. Sometimes to a net oil required repeated automatic spraying and environmental characteristics of the device with the further development of science and technology, any excess mist way more advanced, automatic spray painting equipment operating environment to provide special equipment metal spraying, spray paint room temperature Fang large metal spraying, painting work to meet the requirements of humidity, light, air cleanliness, such as a large spray booth airflow from one end of the room to the other side, the low cost of this type, Easy to install, paint mist spraying large organic dust emission limits will be produced and processed when is green paint equipment.
