What is the effect of pottery treatment on iron parts vs iron-based phosphating? At a glance

化学陶瓷转化膜技术。 Iron is a relatively common metal in our daily life and industry. The pretreatment process of iron generally uses traditional iron-based phosphating. After phosphating, the corrosion resistance of iron can be enhanced. Production requirements, but phosphating will produce a large amount of phosphating slag, and during the production process, carcinogen sodium nitrite will be used as a phosphating accelerator, which will seriously affect the human body and the environment. It is a new type of environmentally friendly ceramic chemical conversion film technology.

Ceramicizing agents usually form a nano-scale ceramic film on the metal surface based on zirconium salt. It does not contain heavy metals, phosphates and any organic volatile components, and almost no sediment is generated during the film formation reaction. It can process iron, zinc, aluminum, magnesium and other metals. The conversion film must have a certain anti-corrosion ability to ensure that the part does not return to rust before spraying, and can also increase the roughness of the surface of the part and enhance the bonding force between the coating and the substrate.
