摘要
热水器中的阀体零部件质量对于整机的性能起着重要的作用,阀体属于热水器的关键零部件,需重点防护。本文主要研究铝阀体表面化学无铬钝化成膜工艺,使用不同的试验药剂和试验方法制作样品,在施工工艺和膜层性能方面综合对比,分析各种无铬钝化成膜工艺的特点,为后期生产提供实验依据。
The quality of valve body parts in water heater plays an important role in the performance of the whole machine.The valve body is a key part of water heater,which needs special protection.In this paper,the chemical chromium-free passivation film-forming technology on the surface of aluminum valve body is mainly studied.Different test reagents and test methods are used to make samples,and the characteristics of various chromium-free passivation film-forming technologies are comprehensively compared in terms of construction technology and film performance,which provides experimental basis for later production.
