Fluoropolymer Reactor Coating Peels and Cracks

The anti-corrosion coatings used on the surface of PTFE-lined reactors are primarily epoxy asphalt coatings. Under the influence of external environmental conditions, delamination and cracking may occur. The reason for cracking in the surface paint film is due to improper shrinkage during the drying and curing process. Therefore, it is crucial to address the issue of paint cracking on the surface of PTFE-lined reactors.
The primary reasons for the delamination and cracking of the lining paint on the PTFE-lined reaction kettle are as follows:
During the spraying process, if the surface paint film is too thick, it typically leads to cracking when the thickness of the epoxy asphalt exceeds 120μm under normal circumstances.
The surface roughness is too low, often resulting in uneven roughness on the weld beads.
High humidity and poor ventilation accelerate surface curing and can also lead to paint film cracking.
Corrosion-resistant coatings are predominantly used on the surface of objects to protect the internal lining of four-fluoroethylene reactors from corrosion. In industrial construction, their usage surpasses that of corrosion-resistant paints, and they are extensively employed in various fields such as chemicals, aviation, oil pipelines, vessels, steel structures, bridges, and oil well channels.
Due to the variety of anti-corrosion coatings in the lining of the four-fluorine-lined reaction kettle, there are significant differences in pricing, functionality, performance, and types. Without professional expertise, it's easy to make errors in engineering calculations and quality control. To address these issues, in addition to consulting with professional paint engineers, you can also conduct your own tests to determine the corrosion resistance of the anti-corrosion paint.
