Processing technology for the Sa2.5 level shot blasting, epoxy zinc-rich primer, epoxy iron-cloud intermediate paint, polyurethane top coat coating.
Advantages
- Q355B material has high strength, good toughness and strong corrosion resistance, so it can maintain better performance in the process of use and extend the service life of the equipment.
- The international standard for sandblasting rust removal on metal surfaces adopts SIS055900, which is divided into Sa1, Sa2, Sa2.5 and Sa3. Compared with ordinary shot blasting rust removal, Sa2.5 level rust removal surface cleaning, strengthening, finishing and deburring is more effective.
- Epoxy zinc-rich primer is a special coating, with epoxy resin and zinc powder as the main raw materials, by adding thickeners, fillers, additives and solvents. This kind of coating is especially suitable for the surface of steel pipes, storage tanks, steel structures, containers, etc. Its high zinc powder content endows the paint film with excellent antirust performance and cathodic protection. It can provide long-term protection in wet or corrosive environments.
- The polyurethane topcoat is resistant to solvents, gasoline and salt water, providing good protection to the substrate and showing good anti-corrosion properties.
