Abstract

The purpose of this study is to identify the staining factors through experiments with plastics vulnerable to pollution and to propose grounds of the staining prevention for application in the design stage. A total of 30 prototypes were built for plastic experiments, with eight thermoplastics and various sloped walls and azimuth angles. The results of the experimental survey by type, angle, azimuth in six phases over a year are as follows. The staining rate of plastic is proportional to the static amount and surface roughness, and the higher the staining rate, the more efficient the antistatic agent is. And the staining degree was high from the angle below the critical angle. In order to reduce the staining rate at critical angles, the results of the application of various antistatic agents showed that conductive inorganic materials were the most efficient. In addition, the staining rate for each azimuth was proportional to the wind speed, and the higher the staining rate, the higher the wind speed, the more efficient the antistatic agent was found. These results provide convincing evidence in choosing antistatic agents, and it is expected that the experimental data collected and the staining factors according to material, angle, and azimuth will be used as useful grounds to staining prevention in the initial design stage.
