通常工件表面上都有氧化皮,油脂,灰砂,污浊等,如果这些脏物不除去,就不能充分发挥涂层的效能.因此,必须进行各种涂漆前处理.被涂物的材料有:金属、木材,塑料,混凝土,皮革等不同物质.其形状、大小,用途,性能要求和使用环境千差万别.为适应不同要求,必须进行适当的前处理,涂料和涂漆方法.本文谨对涂漆前处理和涂层效能的相关性加以阐述. Usually the surface of the workpiece are oxide, grease, lime sand, dirty, etc., if these dirt is not removed, it can not give full play to the effectiveness of the coating.Therefore, must be carried out a variety of paint pre-treatment. : Metal, wood, plastic, concrete, leather, etc. Its shape, size, use, performance requirements and use of the environment vary widely. In order to meet different requirements, must be appropriate pre-treatment, coating and painting methods. The relationship between paint pretreatment and coating effectiveness is illustrated.
