Application of epoxy zinc-rich primer
Epoxy zinc-rich primer has high zinc powder composition, good electrical conductivity, and excellent corrosion resistance. Common roads and bridges, storage tanks, shipping containers, steel frame structures, seamless steel pipes, deep sea service platforms, ships, port equipment, etc. are safe Protective spraying.
Application of epoxy zinc-rich primer
The epoxy zinc-rich primer is mainly used for road bridges, ships, offshore crude oil drilling platforms on water, seaport machinery and equipment, and all sandblasted walls or materials. The content of zinc powder in epoxy zinc-rich primer is above 90%. Because of the high content of zinc powder in architectural coatings, the zinc powder particles can be in deep contact with the surface of the steel to be coated, which has the effect of photoelectric catalytic cathodic protection of pipelines. Zinc-rich primer not only has the function of organic chemical anti-rust treatment of general zinc powder anticorrosive paint, but also has the function of photoelectric catalytic cathodic protection of pipelines.
Supporting facilities for epoxy zinc-rich primer
Generally, the spraying management system of epoxy zinc-rich primer + epoxy resin mica intermediate paint + acrylic polyurethane topcoat is more common. According to different anti-corrosion natural environment and requirements, project construction plans are also different.
Construction of epoxy zinc-rich primer
According to the proportion of paint: epoxy curing agent = 10:1 (net weight ratio), slowly add epoxy curing agent to the main paint, and stir evenly. Let it sit for ten to twenty minutes. The maturation time and the usable period decrease with the increase of temperature. The equipped paint should be used up within 6 hours. Paint materials beyond the usable period should be discarded and not suitable for reuse.
The surface of the project is required to be cleaned up and dry; the surface temperature of the wall or material with an air humidity of <85% needs to be 5℃-40℃. The surface of the wall or material must be 3℃ above the leak point from beginning to end to prevent water vapor from solidifying; Apply paint thinner; in small and enclosed indoor spaces, engineering construction needs to ensure excellent natural ventilation. Use airless spray paint, gas spray paint, paint or roll paint spraying methods.
