FIELD: chemistry. ^ SUBSTANCE: invention pertains to the method of manufacturing fluoroplastic, which can be used for making protective coating for metallic and/or any type of decorative surface, for preservation of metallic surfaces of components without further depreservation and as a component part of antifriction additives, including engine oil of automobiles. The method lies in that, the pseudo-boiling bed, in which the fluoroplastic is put, is heated up to 480-540C. Simultaneously through the layer of fluoroplastic, a stream of inert gas is passed, heated up to 400-500C. The inert gas used is denser than atmospheric air. As a result, the fluoroplastic is turned into a fine-dispersed phase due to its evaporation. Later, the fluoroplastic particles are gradually cooled down to temperature between 150C and 20C. The fluoroplastic particles are then collected and the desired product is obtained. ^ EFFECT: improved anti-friction properties and increased output of the product. ^ 2 cl, 4 ex |
