Изобретение относитс к нанесению покрытий на издели .The invention relates to the coating of products.
Известен способ формировани на поверхности изделий олов нных покрытий путем их обработки маслом при температуре, превышающей температуру плавлени покрыти .A known method of forming tin coatings on the surface of products is by treating them with an oil at a temperature above the melting point of the coating.
Однако этот способ не обеспечивает получение на издели х качественных покрытий, так как при отекании масла с поверхности еще незафиксировавшегос покрыти , на нем образуютс масл ные дорожки.However, this method does not provide for obtaining high-quality coatings on the articles, since when the oil drains from the surface of the still unrecorded coating, oil tracks form on it.
Предлагаемый способ состоит в том, что издели дополнительно обрабатывают маслом при температуре, не превышающей температуру плавлени покрыти , повыша тем самым его качество.The proposed method consists in that the products are further treated with oil at a temperature not exceeding the melting point of the coating, thereby increasing its quality.
Сущность способа заключаетс в последовательной обработке покрыти маслом сначала при температуре, превышающей температуру плавлени покрыти , а затем при температуре , не превышающей температуру плавлени покрыти .The essence of the method is to sequentially treat the coating with oil, first at a temperature above the melting point of the coating, and then at a temperature not exceeding the melting point of the coating.
Дл последовательной обработки можно использовать одно и то же масло, а также масла с различной плотностью. Диапазон температур при обработке покрытий маслом подбирают в каждом конкретном случае экспериментально , так как он зависит от толщины покрыти , в зкости масла, температуры его вспышки и окисл емости, массы обрабатываемого издели и теплопроводности его материала , времени обработки маслом и других факторов.For consistent processing, the same oil can be used, as well as oils with different densities. The temperature range in the treatment of oil coatings is selected experimentally in each case, since it depends on the thickness of the coating, oil viscosity, flash point and oxidation capacity, the mass of the processed product and the thermal conductivity of its material, oil processing time and other factors.
Пример. Карточки из белой жести, покрытые оловом, погружают в вертикальном положении в хлопковое масло, нагретое до температуры выше плавлени олова (245°С), затем в хлопковое масло, нагретое до температуры ниже плавлени олова (225°С), после чего извлекают на воздух. Олов нное покрытие на карточках затвердело непосредственно в масле . Поэтому при извлечении карточек из масла на воздух на их поверхности не образуетс масл ной дорожки.Example. Tin-coated tinplate cards are immersed in a vertical position in cottonseed oil heated to a temperature above the melting of tin (245 ° C), then cotton oil heated to a temperature below the melting of tin (225 ° C), and then removed to air . The tin coating on the cards was hardened directly in the oil. Therefore, when extracting the cards from the oil to the air, there is no oil track on their surface.
