Latest News: In order to solve the harm caused by corrosion, Niwang Technology has applied graphene technology to anti-corrosion coating products. Based on the excellent characteristics of graphene, the performance of traditional anti-corrosion coatings has been greatly improved.

At present, based on this technology, Niwang Technology has developed 6 kinds of graphene-modified coating products according to different use environments and anti-corrosion requirements: graphene composite ceramic corrosion-resistant resin coating, graphene-modified anti-corrosion coating, graphite Graphene-modified functional coatings, supporting industrial anti-corrosion coatings, industrial/commercial floor coatings and graphene-modified powder coatings. Among them, the graphene composite ceramic corrosion-resistant coating has broken the technical monopoly of foreign countries in this field for more than 20 years.

Since the breakthrough in the application of graphene in the field of anti-corrosion coatings by Niwang Technology, various modified coatings such as graphene composite coatings have become an important application research field of graphene for a while. Because graphene has many performance advantages such as high hardness, ultra-thinness, and strong flexibility.

As a nanomaterial, graphene “small size effect” can fill the coating defects, enhance the coating density, delay and prevent the entry of corrosion factors. When graphene is added to the zinc powder coating, the graphene can form a stable conductive grid, which can effectively improve the utilization rate of zinc powder.

From the actual effect, adding about 5% graphene powder can reduce the usage of zinc powder by 50%. At the same time, the graphene coating can form a physical barrier layer between the metal surface and the active medium, which has a good protective effect on the base material.

In addition, graphene-modified coatings have other characteristics that are sought after by many researchers. For example, the commonly used polymer coatings are easily scratched and have weak protection performance. After replacing the protective film with graphene, the metal’s The corrosion rate is obviously slower and the damage resistance is enhanced. It will also be reused in the fields of marine anti-corrosion, metal anti-corrosion, and heavy anti-corrosion.
