Description
Известен способ очистки от цемеитов и окислов железа металлических рабочих поверхностей формующего оборудовани , используемого нри изготовлении строительных изделий из бетона и подобного материала.There is a known method of cleaning metal cements of forming equipment from cemeites and iron oxides used in the manufacture of building products from concrete and similar material.
Однако известный способ осуществл етс вручную или с применением малой механизации , что представл ет собой трудоемкий и длительный процесс.However, the known method is carried out manually or using small-scale mechanization, which is a laborious and lengthy process.
Цель изобретени - уменьшение трудоемкости процесса очистки и улучшение ее качества . Дл этого по предлагаемому способу очистку осуществл ют посредством нанесени на рабочие поверхности пасты на основе ннгибированной кислоты с последующим смыванием ее водой через 1-2 час, после чего поверхности пассивируют фосфотирующим раствором .The purpose of the invention is to reduce the complexity of the cleaning process and improve its quality. To do this, according to the proposed method, the cleaning is carried out by applying to the working surfaces of the paste based on nbibirovannogo acid, followed by rinsing it with water after 1-2 hours, after which the surface passivated with a phosphating solution.
Сущность предлагаемого способа заключаетс в следующем.The essence of the proposed method is as follows.
Пасту на основе ингибированной кислоты нанос т на рабочую поверхность, подлежащую очистки, обычным растворонасосом или вручную.The inhibited acid based paste is applied to the work surface to be cleaned with a conventional mortar pump or manually.
Пасту, нанесенную тонким слоем на поверхность , через 1-2 час смывают струей воды, после чего поверхность пассивируют фосфотирующим раствором.The paste applied with a thin layer to the surface is washed off with a stream of water after 1-2 hours, after which the surface is passivated with a phosphating solution.
Рабоча поверхность форм совершенно очищаетс от цемента и окислов железа.The mold work surface is completely cleaned of cement and iron oxides.
