The aim of the work was to investigate the influence of the surface texture of composite based on PA6, intended for wet painting, on the stability of the colour and gloss parameters. The stability of the paint coating was required to be maintained despite exposure to mechanical stress resulting from attempts to manually remove graffiti stains. The study examined the influence of surface texture on the effectiveness of cleaning. In the case of painted surfaces from which graffiti stains were effectively removed, the roughness, colour parameters and gloss of the paint coating were measured. During the research, it was found that roughness after painting decreased to the value of Ra < 2.00 µm meets aesthetic expectations and at the same time ensures the effective removal of graffiti stains. For this surface, there were no negative effects of the mechanical impact on the textures or quality parameters of the coating as a result of manual graffiti removal. As a result of the conducted research, the recommended maximum values of roughness and textures of the surfaces to be painted were determined in order to ensure a sufficiently low amount of work necessary to effectively remove traces of graffiti.
这项工作的目的是研究用于湿涂的基于PA6的复合材料的表面纹理对颜色和光泽参数稳定性的影响。尽管受到试图手动去除涂鸦污渍所产生的机械应力的影响，仍要求保持油漆涂层的稳定性。该研究考察了表面纹理对清洁效果的影响。对于能有效去除涂鸦污渍的涂漆表面，测量了油漆涂层的粗糙度、颜色参数和光泽度。在研究过程中发现，涂装后的粗糙度降低至Ra < 2.00 µm的值既符合美学期望，同时又能确保有效去除涂鸦污渍。对于这种表面，手动去除涂鸦不会对涂层的纹理或质量参数产生机械冲击的负面影响。通过进行的研究，确定了待涂表面粗糙度和纹理的推荐最大值，以确保有效去除涂鸦痕迹所需的工作量足够低。
