Quality of paint and varnish coatings of medical products and problems of raising it

Conclusions

1. In order to raise the quality of painting of medical products while at the same time reducing the net cost, it is necessary to:

• a) Paint articles made of rolled ferrous or nonferrous metals with a cleanness of ∇6 (which wholly obviates filling and sharply reduces the number of operations involved in the technological process of painting, while increasing the quality, reliability, and protective properties of the coating);

• b) Degrease the surface to be painted with MEA and OP-7 aqueous solutions (this sharply increases the corrosion resistance of a paint or varnish coating);

• c) Use MS-006 quick-drying alkyd styrene filler for local filling of welding seams, etc., instead of PF-002 lacquer filler; the former dries in the cold, whereas the latter requires hot drying or prolonged drying in air of normal temperature; and

• d) Adopt the method of hand electrospraying instead of painting with a pneumatic sprayer in all cases where there is extended use of monotypic paint or varnish materials of the same color.

2. Taking the recommended measures will raise the level of paint and varnish coatings to meet the requirements of the world standard. Moreover, these measures assure an economic gain on the order of 140,000 rubles and an annual saving of paint and varnish materials on the order of 150 tons (approximate calculations for the plants surveyed).
