Heavy duty anticorrosive coating used on Rust
The function of the coating is mainly physical barrier, which separates the metal matrix from the external environment, so as to avoid the contact between the metal and the surrounding environment and play a protective role.
There are two reasons for coating failure: one is that the coating itself has defects and micropores; The second is the inevitable coating damage in the process of construction and operation, which exposes the metal to the corrosive environment and forms corrosion.
During metal corrosion, MLIN engineers found that in a short time, the mechanical barrier and shielding effect of the coating is very obvious from the macro point of view. However, due to the coating composition material itself and film formation, it is difficult to make this complex system reach the ideal state, especially from the time and micro point of view, the non-uniformity of coating components, micropores Cracks are unavoidable in practice, and will gradually initiate and expand with time under the action of the environment to form a transmission channel that can make the environmental corrosive medium reach the metal matrix under the coating. In addition to enhancing the mechanical barrier performance of the coating, pigments, metal powders, scales and other components should be added in the coating preparation, In order to increase the corrosion inhibition, passivation and electrochemical protection of the metal matrix during the penetration of environmental medium.
After analyzing and summarizing the failure causes of the coating and the continuous improvement and practice of the coating on the film-forming materials, a MLIN anti-corrosion coating which can be integrated on the surface and bottom of rust is introduced.
The coating is dense and impermeable.
The resin with high cross-linking density and good anti-corrosion performance is selected. During the curing process, it is continuously dense, the molecular gap is reduced, and the resin condenses to form a continuous and dense film to block the penetration of external substances.
The coating has strong adhesion and will firmly adhere to the substrate surface; Good flexibility, the repeated deformation of the substrate is not affected, and the coating still has good flexibility after 3 years of use;
During use, the coating will be exposed to wind, sun, rain, snow and sand, and the coating will have mechanical scratches, microcracks and cracks. As long as the coating does not damage the substrate, the coating can still be protected continuously,
The coating is a single component, high solid content product with simple construction and strong covering power. It is suitable for various substrate surfaces, can play a good role in mechanical barrier and shielding, and is suitable for maintenance and renovation construction;
