The production process is highly automated
During production, the coating is completed in one go, so that every powder particle of the epoxy powder anti-corrosion coating can Melt bonding allows all components to be evenly combined to ensure continuous and stable uniformity of the coating during the coating process and after the coating is formed. Moreover, its painting process will not produce three wastes of pollution.
Excellent bonding performance with steel
During construction, the fused epoxy powder anti-corrosion coating can be melt-bonded and fully melted and flowed, so that it evenly covers the surface of the steel pipe and there is no gap between it and the substrate. gaps to achieve complete integration. Generally, the shear bond strength of anti-corrosion coatings is below, while the shear bond strength of epoxy powder can reach above. In addition, chemical reactions can occur during shear bonding. The main reason is that the epoxy powder resin is cured and cross-linked by heat to become a continuous thermosetting polymer, which reacts chemically with the surface of the steel pipe to achieve a certain chemical bonding effect.
Has strong resistance to cathodic stripping
As one of the key indicators to measure whether an anti-corrosion coating can coordinate with cathodic protection, cathodic stripping generally involves applying a cathodic protection current. After a period of time, the coating can The peeled area is measured in radius. The peeling radius of other coatings is generally larger than that of epoxy powder coatings, while that of epoxy powder coatings is smaller than. Because the sintered epoxy anti-corrosion coating has this thermosetting cross-linked molecular structure and a certain degree of chemical bonding with the steel pipe, it has excellent performance as an anti-corrosion coating system.
Has strong impact resistance
Epoxy powder coating has a relatively hard texture, can be firmly bonded to metal materials, and has high impact resistance. General coatings can hardly meet this requirement. This enables the sintered epoxy anti-corrosion coating to meet the mechanical performance requirements of steel pipes such as extrusion, impact, friction and bending when stacking and transporting pipes under different operating environmental conditions.
Has good temperature resistance
Epoxy powder coating is the one with the best temperature resistance among various anti-corrosion coatings currently used, and its operating temperature resistance is as high as ~℃. Moreover, the repairing method included in the sintered epoxy anti-corrosion coating technology is simple, feasible and compatible with the anti-corrosion of the pipe body.
Has good environmental resistance
The sintered epoxy anti-corrosion coating can achieve corrosion resistance and aging resistance in various buried, overhead, underwater and other environments when the pipeline is running, as well as the corrosion resistance and aging resistance of the pipeline when it is running. Requirements for resistance to physical stress, biological erosion, and plant root penetration in various environments.
