Four types of substrate for color coated panels
The invention relates to a color coated steel plate of cold-rolled base plate, which is produced from cold-rolled base plate and has a smooth and beautiful appearance and the processing performance of cold-rolled base plate. However, any small scratch on the surface coating will expose the cold rolled substrate to the air, so that the exposed iron will quickly form red rust. Therefore, such products can only be used for temporary isolation measures with low requirements and as interior materials.
Two, hot dip galvanized color coated steel plate organic coating on hot dip galvanized steel plate to get the product is hot dip galvanized color coated plate. Hot dip galvanized color coated plate in addition to zinc protection, the surface of the organic coating also plays a role in isolation protection, rust prevention, service life is longer than hot galvanized plate. The zinc content of hot-dip galvanized substrates is generally 180g/m2(double-sided), and the maximum zinc content of hot-dip galvanized substrates for external use is 275g/m2.
Three, hot aluminum zinc coating plate according to the requirements, can also use hot aluminum zinc plate as a color coating substrate (55% ai-zn and 5% ai-zn).
Four kinds of electrogalvanizing color coating plate electrogalvanizing color coating plate is the base plate, coated with organic coating baking products for electrogalvanizing color coating plate, because the zinc layer of electrogalvanizing zinc plate is thin, usually zinc content is 20/20g/m2, because this product is not suitable for use in the outdoor production of walls, roofs and so on. But because has the beautiful appearance and the fine processing performance, therefore mainly may use in the household appliances, the sound, the steel household appliances, the interior decoration and so on.
