The surface of Jinan galvanized pipe is very smooth after treatment. The common paint cannot attach to the surface at its root, and it will fall down in a short time. The purpose of galvanizing is to prevent corrosion, and further coating for decoration or protection is normal.
The common galvanized pipe paint is phosphating primer and epoxy zinc yellow primer, but both of them need to polish the primer and damage the protection of zinc. In addition to acid substances such as phosphoric acid and zinc chromic acid, the chemical reaction of zinc, consumption of zinc and protection effect of zinc are greatly reduced.
Most of the paints on the market, such as alkyd paint, antirust paint, polyurethane paint, acrylic paint, etc., can not be directly sprayed on galvanized pipes, the main reason is that the paint falls off.
This paper introduces a special coating for galvanized pipe, which is ed1000 epoxy primer. The adhesive force between ed1000 epoxy primer and base material is very strong. It does not need sand blasting or polishing. It can remove oil stain and save labor and material cost by scrubbing the surface with organic solvent. The coating itself does not contain heavy metals, the salt spray resistance time is 1000 hours, and it will not react with zinc, which can realize the two-layer protection of the combination of zinc coating and coating layer. The coating is also suitable for stainless steel, aluminum alloy, copper, magnesium aluminum alloy, non-ferrous metals, etc.
Ed1000 epoxy primer is firmly combined with galvanized pipe. Once the primer is determined, the choice of finishing is simple. According to the specific use environment, epoxy top coat, polyurethane top coat, acrylic polyurethane top coat, etc. can be selected. The top coat and epoxy primer are used together to play the role of overall decoration and protection.
