Description

В практике гальванического хромировани  деталей места деталей, не подлежащие хромированию, тщательно изолируют, а при хромировании в саморегулирующемс  электролите надежно защищают от растравливани . Известные материалы такого назначени , например цапон-лак, при хромировании в саморегулирующемс  электролите нельз  использовать в качестве изол ционного материала, а грунт ВХГМ  вл етс  остро дефицитным материалом. Другие марки лаков (АК-2, бекелитовый ОНИЛХ-3, перхлорвиниловый) также не имеют высокой стойкости в саморегулирующемс  электролите.In the practice of galvanic chrome plating of parts, parts that are not subject to chrome plating are carefully insulated, and when chroming in a self-regulating electrolyte they reliably protect against etching. Known materials of this designation, for example, capon-lacquer, cannot be used as an insulating material when chromium plating in a self-regulating electrolyte, and VHGM primer is an extremely scarce material. Other brands of varnishes (AK-2, Bekelite ONILH-3, perchlorovinyl) also do not have a high resistance in self-regulating electrolyte.

Описываемый способ обеспечивает надежную запипу от растравливани  металла детали при хромировании в саморегулирующемс  электролите .The described method provides reliable protection from metal etching of the part during chromium plating in a self-regulating electrolyte.

Достигаетс  это тем, что повер.хности деталей, не подлежащ,ие хромированию , покрывают в 3-4 сло  с промежуточной сушкой каждого сло  на воздухе цапон-лаком с добавкой в него 25 - 35% (по объему) грунта ДЬ 138 (ГОСТ). При полном покрытии деталей указанным составом места, подлежащие хромированию, зачищают от покрыти  ножом или другими инструментами, издели  или детали, иод.чежащие покрытию , перед их хромированием подвергают очистке от загр знени  и обезжиривают в ())ганическом растворителе. После хро.мировапи  защитную пленку с изделий снимают, раствор ют в апетоне и используют повторно дл  покрыти .This is achieved by the fact that the details of the parts, which are not subject to chrome plating, are covered in 3-4 layers with intermediate drying of each layer in air with a tsapon varnish with 25 - 35% (by volume) of DB 138 (GOST) soil added to it. . When the parts are completely coated with the specified composition, the places to be chrome-plated are cleaned from knife or other tools, products or parts iodine-coated, before they are chrome-plated, cleaned from dirt and degreased in ()) mechanical solvent. After chromium, the protective film from the products is removed, dissolved in the apetone and reused for coating.

Предложенный состав .ч качестве .итного материала может быть рационально использован в гальванических процессах, работающих на кислых и щелочных растворах, и, в частност, при осталивании.The proposed composition of the .ch quality material can be rationally used in electroplating processes working on acidic and alkaline solutions, and, in particular, during ostalivanie.

Описанный способ и состав проверен и внедрен в гальваническом цехе Авторемонтного завода Ленинградского Упра)лени  автомобильного транспорта.The described method and composition has been tested and implemented in the electroplating shop of the Autorepair Plant of the Leningrad Administration of motor transport.
