Outdoor corrosion structure of the metal structure is more serious, good anti-rust anti-corrosion work is imperative, but many people do not know what kind of paint, the following to introduce you, different projects and kinds of paint and its supporting Program.
First, construction works
1. Scaffolding: Alkyd iron red anti-rust paint, alkyd red Dan anti-rust paint.
2. Lifting facilities: Alkyd iron red anti-rust paint + alkyd enamel. Acrylic Primer + Acrylic Finish.
4. Underground pipes: epoxy coal tar pitch (bottom, middle, surface and glass cloth matching). 5. Underground pipeline environment-friendly coating: natural asphalt paint. 6. Exterior wall coating: epoxy closed primer + epoxy paint + fluoride carbon finish.
Second, the road facilities 1. Highway facilities, the use of anti-rust paint a lot of places, such as railings, signs, street lamps and so on. 2. Usually selected supporting: epoxy zinc-rich primer + epoxy cloud iron intermediate paint + acrylic polyurethane finish.
Third, the marine climate, bridges, iron sea climate, for salt spray resistance requirements for outdoor weather resistance, resistance to ultraviolet light, heat and other requirements are higher. Recommended use: epoxy zinc-rich primer (high zinc content) + epoxy cloud iron intermediate paint + fluoride carbon finish matching.
Fourth, galvanized steel components In addition to ordinary steel components, many places using galvanized steel components, such as galvanized pipe, galvanized sheet, galvanized angle, etc., are also a large number of applications. For galvanized steel components, the anti-rust paint can not use alkyd anti-rust paint, recommended the use of epoxy zinc yellow primer and epoxy ester zinc yellow primer. The topcoat can be selected according to the type of primer required.
