(1) when annealed plastic ABS is formed, it is easy to form internal stress and easy to crack at the stress concentration after coating. Annealing or surface treatment can be used to eliminate stress. Annealing treatment is to heat the ABS plastic molding parts below the thermal deformation temperature, that is, 60 degrees centigrade, and heat preservation 2H. In order to reduce investment in equipment, the whole surface treatment can be used to improve the surface condition. The formulation and process of the whole surface treatment are listed in Table 1. Table 1 whole surface treatment formula and process parameters / 1 water / 3 temperature / temperature / C room temperature treatment time /mi15 - 20 (2) oil removal ABS plastic parts are often contaminated with oil, hand sweat and demoulding agent, which will make the adhesion of the coating worse, the coating produces cracking, foaming and shedding. Oil removal should be carried out before coating. ABS plastic parts are usually cleaned with gasoline or alcohol and then chemical degreasing. The process formula is listed in Table 2. Table 2 the residual alkaline solution on the surface of the workpiece should be thoroughly cleaned after the process parameters of sodium hydroxide (S/L) sodium 50~70 phosphate (S/L) 20~30 sodium carbonate (S/L) 10~20 surface active agent (S/L) 5~10 temperature / 50~60 treatment time /min10 to 15 chemical oil, and cleaned with pure water ***, drying or drying. (3) electrical and dust removal plastic products are insulators, and the surface resistance is generally around 1013 ohms, which is easy to generate static electricity. After charged, it is easy to adsorb tiny dust in the air and stick to the surface. It is very difficult to remove dust from electrostatic adsorption by general blowing method. High pressure ionized air flow has good effect in addition to electrostatic precipitator.
