Description

Изобретение относитс  к способам защиты химической аппаратуры от коррозии с применением каучука и виниловых смол.This invention relates to methods for protecting chemical equipment from corrosion using rubber and vinyl resins.

Описываемый способ защиты от коррозии дает эффективные результаты защиты аппаратуры и коммуникаций, работающих в т желых услови х, например: НС1 - газ при высоких температурах пор дка 120-150°, НС1 - газ + следы хлора при температурах 75-85° в прпсугствии больших количеств примесей масел, органических смол и прочих продуктов, вызывающих сильное набухание, окисление обычных защитных покрытий и т. д. и отличаетс  от известных тем, что на защищаемый объект нанос т иоследовательно слой резиновой смеси на основе севанита , затем севанитоэтиленовый лак и слой асбовинила, после чего объект термически обрабатывают известным методом.The described method of protection against corrosion provides effective results for the protection of equipment and communications operating under severe conditions, for example: HC1 is a gas at high temperatures of the order of 120-150 °, HC1 is gas + traces of chlorine at temperatures of 75-85 ° if it is large amounts of impurities of oils, organic resins and other products that cause severe swelling, oxidation of conventional protective coatings, etc., and differs from the known ones by applying successively a layer of rubber mixture based on sevanite and then sevanitetoethylene on the protected object. ac and a layer of asbovinyl, after which the object is thermally treated by a known method.

Каландрованна  смесь такого состава наноситс  на поверхносгь аппаратуры или трубопроводов, после чего слой сырой обкладки промазывают севанитоэтиленовым лаком, затем последовательно футеруют в несколько слоев асбовинилом и полученное покрытие термически обрабатывают при 75-80° в течение суток.A calendered mixture of such a composition is applied to the surface of the equipment or pipelines, after which a layer of raw lining is coated with sevanithoethylene varnish, then successively lined in several layers with asbovinyl and the resulting coating is thermally treated at 75-80 ° for 24 hours.
