The purpose of the steel structure of the railway is to protect it from corrosion and to ensure safe transportation. Railway coatings are mainly divided into two categories: steel bridge paint and locomotive paint, and other equipment such as electrified railway transmission tower is basically the same as steel bridge coating. First of all, we have to look at the cold spray zinc zinc shield in the railway locomotive vehicles on the painting and railway rolling stock paint and technical requirements.
Railway locomotives and vehicles according to the use of location, the use of different requirements, the use of different types of paint. As the bus factory repair is generally 6 to 8 years, the truck plant repair is generally 8 to 10 years, the locomotive of the aircraft repair is generally 40 million km. Various types of railway rolling stock application of the coating system is as follows.
Passenger car paint in the primer for the zinc spray cold spray zinc anti-rust primer; putty epoxy ester or unsaturated polyester putty; topcoat, including acrylic acid modified acrylic acid, acrylic polyurethane and a small amount of ordinary alkyd paint.
