Vinyl scale mastic Epoxy Mastic anticorrosion high temperature glass scale anticorrosion

  Vinyl resin glass flake mastic is a thermosetting polymer, which combines the excellent corrosion resistance and mechanical properties of epoxy resin, and has the process performance of rapid curing of unsaturated polyester resin
Vinyl ester resin is a kind of unsaturated resin with vinyl ester groups at both ends of the molecule and epoxy resin as the intermediate skeleton
At present, it has been widely used in the anti-corrosion field of chemical industry, metallurgy, construction and other departments of the national economy
In this study, aiming at the corrosive environment in the wet desulfurization device, phenolic epoxy vinyl ester resin is used as the main film-forming material, and the ratio of heat-resistant filler and glass flake is optimized, so that the coating has excellent mechanical properties and good corrosion resistance at 180 ℃, and the corrosion resistance of the coating in sulfuric acid solutions of different temperatures and concentrations is discussed to determine the heat-resistant temperature of the coating in sulfuric acid of different concentrations, It provides a basis for practical application
Performance characteristics: 1 Strong corrosion resistance
It has excellent chemical corrosion resistance, especially acid corrosion resistance
2
Excellent aging resistance
Its anti-aging property is higher than any paint film 3
Good temperature resistance
4
The coefficient of thermal expansion is small   5
Good wear resistance   6
It has good compatibility and can form anti-corrosion coating with various resins 3
5 anti corrosion principle glass flake resin anti-corrosion coating is to mix quantitative glass flakes with a certain diameter and thickness with quantitative polyester, epoxy, vinyl and other resins according to the operating procedures
After strict preparation process, it is prepared into mastic or paint
Apply it to the treated metal surface or the surface of other protected materials with tools such as mud trowel or high-pressure airless spray gun
After curing at room temperature, the lining or coating is obtained 3
6 advantages of glass flake anticorrosion 1
The penetration of medium, gas and steam is far less than that of ordinary FRP
It is not easy to produce medium diffusion, and can effectively avoid physical damage such as bottom erosion, dispersion, bubbling, stripping, etc
2
The shrinkage is small when hardening
Because the glass flake disperses the stress, the residual stress of each contact surface is small, and the coefficient of thermal expansion is also small, so the bonding strength will not decay due to thermal expansion, and the thermal stability is good 3
Wear resistance and abrasion resistance are strong
In case of mechanical damage, it is limited to local areas, and the diffusion trend is small
4
Good repairability
After several years of use, the damaged part can be repaired with simple treatment
5
It has strong adaptability to the protective surface, especially suitable for the corrosion prevention of complex surfaces 6
Good constructability
The scale anti-corrosion can be constructed by spraying, roller coating, scraping and other methods
Good integrity, convenient on-site ingredients, room temperature curing and thermal curing
