Construction method of automobile primer
经过涂装前表面处理后，一般可以直接喷涂头道底漆。is treated with the surface before painting, it can generally be directly sprayed with primer.
For the surface of the metal that has been pickled and rusted, after the roughening treatment, it can be coated with a layer of phosphating primer, or "new strength" alloy primer, British ICI durable erosion primer, and American "DuPont" 810R anti-rust hunting corrosion primer Paint to increase adhesion between the metal surface and the primer.
在于金属表面的防锈和防腐，增加腻子与车身金属表面的粘着作用。 Theof the primer is prevent rust and corrosion on the metal surface and increase the adhesion between the putty and the metal surface of the vehicle body. When spraying the primer, the primer should generally be selected according to the vehicle model. The proposed options during construction are as follows:
1. Selection of primer for domestic busesWhen repairing general domestic buses for spraying the primer, the surface of steel should be FO6-1 iron red phenolic primer, and F06-1 zinc yellow phenol primer for light metals such as aluminum and aluminum alloy.
的底漆选用 2.Selection of primers for high-end orAvailable "Xinjin" protective green primer, P565-8882K fast thick film primer, CICPO82-28 anti-floating red primer,
2K two-component primer, "DuPont" 30SR nitro primer, l505 air-dried primer or 1020R multi-purpose high film thickness primer, "Parrot" brand 285-16 heat-sensitive insulation primer It can be selected according to the paint specified by the manufacturer of the original importing country.
Primer construction requirements; construction should be mainly spraying, and it is required to apply evenly, without leakage, and without flow marks.
Due to the poor adhesion of the coating film on the surface of the coated object or the undercoating layer, scraping the coating film with nails or metal will cause the phenomenon of coating film peeling, which is called peeling. Car paint is easy to peel off ...
