Polymers in Ship Machine Building (Polimery v Sudovom Machinostroyenii).

摘要

The use of polymeric materials in ship machine building permits the successful solution of such important problems as reducing the mass, increasing the traveling speeds, improving service life and reliability, economizing scarce nonferrous metals, raising labor productivity, and reducing labor intensity and operating costs. The volume of production and consumption of polymeric materials is increasing each year. Along with the increase in the volume of production of polymeric materials, their assortment expands each year. The polymeric materials known at the present time possess a wide range of properties and belong to different categories of compounds, from polyolefins (polyethylene, etc.) to polyorganosilicoelemental compounds (polyboroorganosiloxanes, polytitanoorganosiloxanes, etc.). In ship machine building, polymeric materials are used in the manufacture of ship propellers, parts of various mechanisms and devices, sliding bearings, seals, as anticorrosion coatings, etc.
