покраска

1. Major metal deposits and chemical treatment.

anodizing of aluminum alloys, the size of details is 9500x2000 mm and 1450x800 mm, including hard anodizing, the size – 6000x1000 mm;

chemical oxidation of aluminum and magnesium alloys, the size 9500x2000 mm;

cadmium-plating (2700x800 mm) and zinc coating of steel details by after-plating;

chromium-plating and chemical nickel plating of details of titanium alloys and steel:
  - chemical oxidation of steel and titanium alloys;
  - chemical passivation of stainless steel, copper and copper alloys;
  - dimensional chemical etch (milling) of sheets (8000x2000 mm) from aluminum alloys.

 2. Varnish-and-paint coating:

  • primer paint and coloring of details. The major varnish-and-paint materials are of epoxy nature. Heating: convection heating at temperature +90°C and radiant heating at temperature +120°C. The maximum size of details colored is 14500x2000 mm;
  • primer paint and coloring of details, units and assemblies. Coating of non-metallic details. Convection heating and air-seasoning;
  • finishing coat of aircraft.

The technology of aircraft coating with glossy polyurethane and camouflage varnishes made by “AKZO NOBEL…”, Netherlands, has been mastered. The painting hanger provides for coating aircraft of the size 54x40 m and height
12 m.
