Price of glass flakes for plastic products desulfurization flue anti-corrosion scraped glass flakes
Why does glass flake need to be added to heavy-duty anti-corrosion coatings?
As a simple anti-corrosion method, coating is to isolate the medium from the substrate, but there are usually pores in the coating. One is structural pores, whose size is related to the molecular structure of coating film-forming materials;
The other is the pinholes formed by the volatilization of solvents in the coating film-forming process, and the diameters of small molecules such as water, acid and alkali are generally smaller than the structural voids of the coating;
In addition, these media in contact with the coating pass through the coating in a straight line, and the coating cannot be coated very thick (otherwise cracks will occur). Therefore, as for the general anti-corrosion coating, even if the coating can better resist the corrosion of the media in contact, it can not resist the diffusion and penetration of these media to the substrate,
That is to say, ordinary anti-corrosion coatings can only be used for anti-corrosion in the atmosphere, but can not play the role of lining in pipelines and tanks, especially in occasions with liquid medium and high temperature;
The addition of glass flakes changed the coating;
First, the coating can reach the thickness required for anti-corrosion without cracks, because the glass flake divides the coating into many small ***ces, which greatly reduces the shrinkage stress and expansion coefficient of the coating;
Second, because the multilayer of glass flakes are arranged parallel to the matrix, the route of Medium Diffusion and penetration becomes curved, and the time of Medium Diffusion and penetration into the matrix is prolonged.
The water vapor penetration test shows that the glass flake coating with a thickness of 0.1mm is equivalent to the epoxy resin coating with a thickness of 0.7mm.
