Description
Изобретение относитс к области нанесении нокрытий с целью защиты от коррозии металлических подземных сооружений.The invention relates to the field of application of coatings for the purpose of corrosion protection of metallic underground structures.
Известен снособ нанесени иокрытнй на металлическую новерхность, включающий обработку составом, содержащим фосфорную кислоту , желтую кров ную соль н воду.A known coating method is applied to a metallic surface, which includes treatment with a composition containing phosphoric acid, yellow blood salt and water.
Предложенный снособ отличаетс от известного тем, что неред обработкой составом на новерхность нанос т слой смеси двойного суиерфосфата с водой нрн темнературе 16-45°С и высушнвают его ирн той же темиературе. Это сиособствует новьинеиию коррозионной стойкостн нокрыти , так как обеснеч 1ваютс услови дл самовосстановленн защнтного нокрыти в случае наруиюни его силонпюсти и проникновени почвенного раствора к новерхностн металла.The proposed removal method differs from the well-known one in that it is not uncommon to treat a surface with a layer of a mixture of double suierphosphate with water at a temperature of 16-45 ° C and dry it with the same temperature. This contributes to the corrosion resistance of the coating, since the conditions for the self-repair of the protective coating are reduced in the event of its disruption and the penetration of the soil solution to the surface of the metal.
Предложенный снособ осун ествл ют следующим образом.The proposed snoot is osuschestvl as follows.
На прокорроднровавшую поверхность нанос т слой смеси двойного суперфосфата с водой в соотношении 2,8-3,2:1,0-1,2 нрн темнературе 16-45°С и .высушивают его нрн той же темнературе. Затем по высохшему слою нанос т состав, содержащий фосфорную кислоту , желтую кров ную соль и воду (в вес. ч.): фосфорна кислота3-3,5A layer of a mixture of double superphosphate with water in a ratio of 2.8-3.2: 1.0-1.2 nrn to a temperature of 16-45 ° C is applied on the corroded surface and dried it on the same temperature. Then a composition containing phosphoric acid, yellow blood salt and water (in weight parts) is applied over the dried layer: phosphoric acid3-3.5
-2-2
После высыхани второго сло нанос т любое покрытие дл механической защиты, иапример эиокснд 1ое, битумное и т. д.After the second layer dries, any coating is applied for mechanical protection, i.e., for example, eioxand 1, bitumen etc.
Прн приготовленнн смеси двойной суперфосфат измельчают до тонкости портландцел ента и сме1ннвают с водой за 1 -1,5 час до обработки металлической новерхностн. Состав, 1:одержаи1,ий фосфориую кислоту, желтую кров ную соль и воду, пр 1готавливают смешенном комнонеитов за 24 час до начала работ. Состав нредставл ет собой белую однородную массу.The prepared double superphosphate mixture is ground to the fineness of portland target and mixed with water for 1-1.5 hours before the treatment of the metal surface. Composition 1: phosphate, phosphoric acid, yellow blood salt and water, prepared by mixed roomite 24 hours before the start of work. The composition is a white homogeneous mass.
При осущестнленнн предложенного способа доиолните.чьный эффект может быть иолучен при введении 3-5% гексаметафосфата натри в смесь двойного суперфосфата с водой.With the implementation of the proposed method, add the total effect can be obtained with the introduction of 3-5% sodium hexametaphosphate in a mixture of double superphosphate with water.
