摘要
涂装前处理的目的是为基体表面涂层建立良好的基底,以保证涂膜具有良好的防腐蚀性和装饰性。目前,工程机械行业随着对外观品质要求的越来越高和生产效率的提升,逐渐从机械前处理工艺(抛丸、喷砂等)转变为化学前处理(磷化、硅烷、陶化等)。重点叙述了在工程机械行业推广的化学前处理工艺,对磷化及硅烷处理槽液参数控制、电泳工艺参数调整、以及涂层性能等方面进行了介绍,该技术在工程机械行业涂装前处理中获得成功应用。
he purpose of coating pretreatment is to establish a good substrate for the surface coating,so as to provide the coating with good corrosion resistance and decoration.At present,with the increasing requirements of appearance quality and productivity of construction machinery and equipment,the industry has gradually changed pretreatment from mechanical process(shot blasting,sand blasting,etc.)to chemical techniques(phosphating,silane,zirconation,etc.).This paper focuses on Pentatomic’s chemical pretreatment in the industry,and introduces the control of phosphating and silane treatment tank bath,the adjustment of E-coat,and the coating performance analysis.The technology is shownd to be successfully applied prior to the coating of construction machinery and equipment.
