Research on the effect of plasma cleaning machine manufacturers on the corrosion failure of water-based coating defects:
With the country’s increasing emphasis on environmental protection, water-based coatings have become one of the green development directions of the coatings industry due to their environmental advantages. However, there is still a big gap between the performance of water-based coatings and solvent-based coatings. The poor water resistance and corrosion resistance of water-based coatings hinder its wide-ranging application. Chengfeng Zhizhi plasma cleaning machine manufacturers can improve the overall protection of the metal/coating system through the surface treatment of the metal base material, which is conducive to the use and promotion of water-based coatings on metal substrates.
The traditional surface treatment methods of metal substrates, such as electroplating and electroless plating, are likely to cause environmental pollution. As a new surface treatment method, plasma treatment has received widespread attention from the society.

Plasma cleaning machine processing is not only effective, but also green and environmentally friendly. Modification of the surface of the substrate does not greatly change the properties of the surface of the substrate. In addition, it also has the advantages of high safety and easy operation, which can be promoted in the industry.
Plasma is an ionized gaseous substance composed of positive and negative ions generated after some electrons are deprived of atoms and atomic groups are ionized. It is often regarded as the fourth state in which substances other than solids, liquids, and gases exist.
The plasma treatment of Chengfeng Zhizhi Plasma Cleaner manufacturer can connect some functional functional groups such as hydroxyl and carbonyl to the surface of the sample to be treated. After plasma treatment, the hydrophilicity of the surface of the material can be improved, and the spreading performance of the surface can be improved. The organic coating can better wet the surface of the body and reduce the generation of pores, so that the surface of the substrate can be better combined with the coating and delay its failure process.
When the substrate is not plasma-treated, the varnish coating and the metal substrate merely adhere to each other, and after the substrate is plasma-treated, there is an obvious transition layer between the varnish coating and the metal substrate. The coating and the substrate are connected to form a new film layer in the process of adhesion, namely the plasma layer.
Plasma treatment can add some functional groups to the surface of the substrate, such as hydroxyl and carbonyl groups. These groups can react with unsaturated carbon-carbon double bonds, carboxyl groups, hydroxyl groups, ester groups and other groups in the alkyd resin to form chemical bonds, thereby improving the bonding force between the coating and the substrate. In addition, the roughness of the surface can be increased, and the bonding force can be increased.
Plasma cleaning machine treatment brings many active groups on the surface of the metal substrate, so there is a partial chemical bond connection between the plasma layer and the substrate metal, so that the coating and the metal are integrated. Therefore, the appearance of the plasma layer enhances the wet adhesion between the coating and the metal substrate, and the anti-stripping performance of the coating has been significantly improved, which adds a layer of resistance to the water in the process of transmission, and then improves the coating’s performance. Service life and failure time.
By plasma treatment on the surface of the metal substrate, and then coated with water-based alkyd varnish, a comparative analysis was performed with the water-based alkyd varnish coating system that has not been treated by a plasma cleaner. The accumulation of corrosion products at the defects of the substrate surface coating without plasma treatment is more than that of the substrate surface coating after plasma treatment, and the failure rate of the former coating is faster than the latter.
This shows that plasma treatment of the metal substrate can delay the corrosion failure process of the coating and the metal substrate, and increase the service life of the coating. Plasma cleaners can obviously delay the corrosion failure of water-based alkyd varnish coating defects and improve the service life and comprehensive performance of the coating.
