Paint shop

The WZL1’s Paint Shop is designed for painting small and medium-sized parts, but first of all for large structures, such as helicopter, light aircraft of the Cessna type, semi-trailers, etc. The painting process uses both innovative coat application methods and the conventional ones (manual spray guns, pressure sprayers), polyurethane and epoxy of a high solvent content, High Solid type enamels as well as phthalate and cellulose ones. Also water-soluble paints have been implemented for application.

The Paint Shop has the following equipment for paint coat application:

• Combined spray paint and drying hall with its machine room;
• KMWW-20 single-station spray paint booth;
• KMWW-40 2-station spray paint booth;
• SKMe-3 minor parts drying booth.

The combined spray paint and drying hall is a stand-alone building with two large-dimension electric driven doors has the following interior dimensions:

Length x Width:  25.8 m x 18 m;
Height:  min. 9.8; max. 11.4 m (average 10.6 m);
Working area: approx. 464.4 sq.m. (5,000 sq.ft.);
Volume: approx. 4,922.64 cu.m.

The combined spray paint and drying hall operates using the following work cycles:

• Manual Work Cycle: old coat stripping, degreasing, puttying, sanding, etc. – blown-in air temperature +20°C;
• Paint Application Cycle: blown-in air temperature +25°C;
• Drying Cycle: circulating air temperature up to max +35°C.

The working area of the hall is divided into two parts with a folding, manually extended segmented dividing wall of the B x H dimensions = 15.500 m x 7.500 m, that allows for painting operations either across the whole hall area (with the dividing wall folded) or in two independent working areas.

Dimensions of the minor parts paint shop are as follows:

Length x Width: 11.8 m x 11.35 m;
Height : min. 3.9; max. 4.98 m (average 4.44 m);
Working area: approx. 101.52 sq.m. (1091 sq.ft.);
Volume: approx. 452.89 cu.m.

After paint coat application the painted parts are placed in the drying booth where the coat partially dries and then is hardened at a controllable temperature ranging from 35°C to 220°C.
