Rail fishplate rust prevention treatment
Antirust treatment
Coating rust prevention method
Paint selection:
Use high-performance anticorrosive coatings, such as cold galvanized coatings containing high zinc content (such as Robaru coatings) or synthetic resin coatings. These coatings can form a strong paint film, effectively isolating the fish plate and the surrounding corrosive media contact.
Coating process:
Before painting, it is necessary to thoroughly clean and remove rust on the fishtail plate to ensure that the surface is free of oil and rust.
When painting, brush, spray or dip coating can be used to ensure that the paint is evenly covered on the surface of the fishplate.
After painting, it is necessary to wait for the paint to dry and cure fully to achieve the best anti-corrosion effect.
Hot-dip galvanizing process
Process principle:
Hot dip galvanizing is to immerse the fishplate in molten zinc liquid and form a zinc-iron alloy layer on the surface of the fishplate through chemical reaction. This alloy layer has extremely high corrosion resistance and adhesion, which can effectively protect the fishplate from corrosion.
Process features:
Hot dip galvanizing process has the advantages of good anti-corrosion effect, long service life and simple construction.
However, it should be noted that the hot-dip galvanizing process has certain requirements for the material and shape of the fishplate, and the cost is relatively high.
