Description
Изобретение относитс к нанесению защит- ных покрытий химическим путем в частности к водным растворам дл фосфатировани и может быть использовано в металлургии fi машиностроении дл получени покрытий, служащих подсмазочиым слоем при холодной деформации.The invention relates to the application of protective coatings by chemical means, in particular to aqueous solutions for phosphating, and can be used in metallurgy fi engineering for the production of coatings that serve as a lubricating layer during cold deformation.
Цель изобретени -,снижение шламо- образооани в процессе фосфатировани .The purpose of the invention is to reduce sludge formation during phosphating.
Указанна цель достигаетс тем, что нанесение фосфатного покрыти на стальную поверхность осуществл етс методом окунани в растворе следующего состава, мас.%:This goal is achieved in that the phosphate coating on the steel surface is carried out by dipping in a solution of the following composition, wt.%:
1,15-3,06 1.15-3.06
PaOs -0,86-2,49PaOs -0.86-2.49

Отход производства пропионовой кислоты - 0,0017-0,092 Дл фосфатировани был приготовлен р д растворов, отличающихс друг от друга количественным содержанием компонентов . Результаты испытаний, иллюстрирующие вли ние концёнтрации к б мпонентов рабочего раствора на шламообразование, приведены в таблице. Изданных, приведенных в таблице видно что при содержании Zn2+, PaOs, N03, Nl2+ выше и ниже предлагаемой концентрации (примеры 4,7,8,11,12,15,16,19)образуетс большое количество шлама. Кроме того, не наблюдаетс улучшени качества фосфатного покрыти и повышение эффективности состава .A waste of the production of propionic acid is 0.0017-0.092 A series of solutions were prepared for phosphating, differing from each other in the quantitative content of the components. The test results illustrating the effect of the concentration of k components of the working solution on sludge formation are given in the table. The published data presented in the table show that when the content of Zn2 +, PaOs, N03, Nl2 + is higher and lower than the proposed concentration (Examples 4,7,8,11,12,15,16,19), a large amount of sludge is formed. In addition, there is no improvement in the quality of the phosphate coating and an increase in the effectiveness of the composition.
При содержании Zn , P20s, NOa, Nr в предлагаемых пределах (примеры 1,2,3,5,6,9,10,13,14,17,18) образуетс мин&- количество шлама.When the content of Zn, P20s, NOa, Nr is within the proposed limits (examples 1,2,3,5,6,9,10,13,14,17,18) min & - amount of sludge is formed.
Обнаружено, что совместное введение в раствор диамида угольной кислоты и технологического отхода производства пропионовой кислоты в предлагаемых пределах приводит к получению мелкокристаллического покрыти и одновременно снижает количество образующегос шлама (примеры 20-28).It was found that the combined introduction of carbonic acid diamide into the solution and the process waste of propionic acid production within the proposed limits results in a fine-crystalline coating and at the same time reduces the amount of sludge generated (Examples 20-28).
