자동차 도장 시스템의 트라이볼로지적 특성에 관한 불량 사례 연구

In recent, the automotive makers have produced the vehicles of many colours that chose by many people. But, if the beautiful painting parts on vehicle appear the variation of paint film by inferiority of paint and chemical effecting, they will be taken the bad influence because of a falling- off in quality. In this paper, the several examples produced in the field identified the fact that give large effect for paint system. The viscosity of coating material affect with paint film formation. When the paint part doesn't make uniform paint film because of lowering viscosity, it made identified inferiority phenomenon by running of paint. The adhesive property of paint surface is affected with roughness. It become so rough that well absorb the coating material. As a result, the researcher certified the phenomenon of orange peel that is collected with certain parts by paint film clod. When the researcher is adhered an alien substance adhesive with paint part during driving in the local where a pollutant contain in air, he identified the inferiority example of paint film because of chemical changing. When the driver keep his car for long time in a garage where is cut the air flowing, he certified the blistering phenomenon of paint film.
