本文总结了73除油、除锈、磷化、钝化“四合一”金属多功能处理液的研究概况。研究表明,以锰盐为主盐,添加有成膜剂、加速剂、活性剂和钝化剂的73液是一种无毒,不污染环境,同时具有除油、除锈、磷化、钝化四种功能的处理液。适用于各种冷轧低碳钢和铝制件涂漆前或塑料粉末静电喷涂前的预处理。性能测试结果表明达到了产品涂装前对表面预处理质量的要求。与同类产品比较,具有使用温度接近室温,槽液酸度低,粘度小,处理后工件表面残液少,易于干燥等优点。73液已作为涂漆和喷塑前的预处理液获得广泛应用。
This paper summarizes 73 oil refining, rust removal, phosphating, passivation, “four in one” metal multi-functional treatment of research. The research shows that, with manganese salt as the main salt, 73 liquid added with film-forming agent, accelerant, active agent and passivating agent is a kind of non-toxic and non-polluting environment, meanwhile degreasing, descaling, Four functions of the treatment solution. For a variety of cold-rolled mild steel and aluminum parts before painting or plastic powder electrostatic spraying pretreatment. The performance test results show that the quality of the surface pretreatment before painting is reached. Compared with similar products, with the use of temperature close to room temperature, acid bath low viscosity, small viscosity, less residue on the surface after treatment, easy to dry and so on. 73 fluid has been widely used as a pretreatment fluid for painting and pre-spray applications.
