Generally, the anti-corrosion failure of the anti-corrosion layer is mainly caused by the corrosion of the resin matrix
The matrix resin first produces weight loss, discoloration, etc
, then causes the bubbling, delamination, peeling or cracking of the material, and finally leads to the failure of the anti-corrosion layer
In particular, the latter, due to factors such as permeability, accelerates the penetration of corrosive chemical media into the interior of the protective layer
Therefore, while selecting the resin matrix with good corrosion resistance, effective measures should be taken to weaken and slow down the penetration of corrosive medium or water vapor
The VEGF scale mastic can provide more effective corrosion resistance than the matrix resin, mainly because the VEGF glass scale can effectively prevent the physical penetration of corrosive media or water vapor The strong impermeability of VEGF scale mastic is related to its material composition
Generally, VEGF scale mastic contains 10%-40% glass scales with different diameters
After the construction of the mastic, the flat glass scales are in parallel overlapping arrangement in the resin continuous phase, thus forming a dense impervious layer structure
The penetration of corrosive medium in the cured mastic must go through countless tortuous paths
Therefore, in the corrosion resistant layer with a certain thickness, the distance of corrosion penetration is greatly extended, which is objectively equivalent to effectively increasing the thickness of the corrosion resistant layer
At the same time, in the case of no glass flake reinforcement, there will be a large number of so-called “ Defects ”, Such as micropores, bubbles and other micro cracks, the existence of these defects will accelerate or accelerate the penetration process of corrosive medium
Once the medium penetrates into these defects, the penetration speed will be improved, and the area of matrix continuous phase contacting corrosive medium will also be increased, thus accelerating the physical penetration and chemical corrosion process
In VEGF glass scale mastic, Because the glass flakes arranged in parallel can effectively separate these “ Defects ”, Thus, the penetration rate of corrosive medium can be effectively inhibited
