乘用车颗粒成因分析预防

Cause analysis of passenger car particles

乘用车涂装的产品质量主要有性能质量及感知质量两个部分。性能主要取决于设备、工艺参数及原材料本身。例如膜厚、油漆硬度、抗老化性等,而感知质量主要取决于涂装管理,例如密封胶的美观性、车身表面的颗粒渣点等。文章通过阐述涂装车身表面颗粒渣点的分析,得出颗粒弊病作为涂装行业最难克服的弊病之一,更需要通过人员管理、材料管控、及时清洁等有效的手段进行管控。同时也应通过新工艺、新方法的创造和实施持续不断的改善颗粒问题的发生,不断的提升油漆产品的品质,为消费者提供精美的产品。

The product quality of passenger car painting mainly includes two parts:performance quality and perceived quality.Performance mainly depends on equipment,process parameters and raw materials themselves.For example,the film thickness,paint hardness,aging resistance,etc.,and the perceived quality mainly depends on the coating management,such as the aesthetics of the sealant,the particle residue on the body surface,etc.By elaborating the analysis of the particle residue on the surface of the painted body,the article concludes that the particle defect is one of the most difficult to overcome in the paint industry,and it needs to be controlled through effective methods such as personnel management,material control and timely cleaning.At the same time,through the creation and implementation of new processes and methods,the occurrence of particle problems should be continuously improved,the quality of paint products should be continuously improved,and consumers should be provided with exquisite products.
