With the development of material anticorrosion technology, the impregnated powder coating has been widely used in the field of metal products protection because of its excellent corrosion resistance. The purpose of this paper is to systematically investigate the corrosion resistance of impregnated powder coating and the scientific mechanism behind it.
The basic principle of the dipping process and the coating process of the dipping powder on the metal surface are described briefly, as well as the important significance of the process in improving the corrosion resistance of metal products.
Second, study on corrosion resistance of impregnated powder coating
1, coating material characteristics analysis: detailed introduction of the composition of the main components of the plastic powder (such as polyethylene, polyvinyl chloride, etc.) on the impact of corrosion resistance, including molecular structure characteristics, chemical stability and physical properties.
2. Experimental methods and evaluation system: The corrosion resistance of different impregnated powder coatings under simulated environment was quantitatively evaluated by means of salt spray test, wet heat cycle test and other testing methods.
3. Practical application case analysis: Combined with practical engineering application cases, the corrosion resistance effect of impregnated plastic powder coating and other anti-corrosion treatment methods is compared and analyzed.
Third, discussion on corrosion resistance mechanism of impregnated plastic powder coating
1, chemical barrier effect: describes how the plastic coating by preventing water and oxygen direct contact with the metal matrix, thereby inhibiting the occurrence of electrochemical reactions, to achieve the purpose of anti-corrosion.
2, physical isolation effect: explain the importance of coating density and adhesion to prevent the penetration of corrosive media.
3, microstructure influence: The use of microscopic analysis technology to reveal the internal relationship between the microstructure of the coating and its corrosion resistance, such as porosity, grain size and other factors.
The current research results on the corrosion resistance of impregnated powder coating are summarized, and the future improvement of impregnated plastic coating technology, the development of new impregnated powder and the depth of corrosion resistance mechanism are prospected.
Through this article, I hope you can have an in-depth understanding of the high performance of impregnated powder coating in corrosion resistance and the scientific principle behind it.
