Description

Сульфанилова  кислота, г3-5Sulfanilic acid, g3-5

Вода, лдо 1Water, ldo 1

О;бща  кислоттность раствор-а составл ет 60-80 точек, свободна  12-15 точек. Соотношбйие общей и свободной кислотностей не должео выходить за пределы (5:1) - (6:1). Процесс фосфатиравани  в предлагаемом pacTiBope провод т при 60-70°С, рН-1,7-2,7 в течение мин.O; the general acidity of the solution is 60-80 points, 12-15 points free. The ratio of total and free acidity does not have to go beyond (5: 1) - (6: 1). The phosphatation process in the proposed pacTiBope is carried out at 60-70 ° C, pH 1.7-2.7 for min.

ПрИмер 1. Издели  из углеродистой стали обрабатывают в растворе, содержащем: Монофасфат цинка, г55EXAMPLE 1. Carbon steel products are treated in a solution containing: Zinc monofasphate, g55

Процесс провод т при 65°С, рП-2,1 в течение 15 мвн.The process is carried out at 65 ° C, rp-2.1 for 15 mV.

Получают плеику толщиной 6 мкм. Ее коррозионна  стойкость, измеренна  капельным методом Г. В. Акимова с помощью раствора , содержащего 82 г/л сернокислой .меди, 13 мл/л сол иой кислоты и 33 г/л хлористого натри , составл ет 10 мин.Get a pleica thickness of 6 microns. Its corrosion resistance, measured by the GV Akimov drop method, using a solution containing 82 g / l of copper sulfate, 13 ml / l of hydrochloric acid and 33 g / l of sodium chloride, is 10 minutes.

Пример 2. Издели  из пружинной стали У8 обрабатывают в растворе, содержащем: Монофоюфат цинка, г60Example 2. Products made of spring steel U8 process in a solution containing: Monophosphate zinc, g60

, Процесс провод т при 65°С, рН-1,8 в течение 20 iMBH.The process is carried out at 65 ° C, pH-1.8 for 20 iMBH.

Получают плевку толЩ|И1ной 8 мкм. Коррозионна  стойкость, из1мереБна  тем же способом , что и в примере 1, составл ет 12 мин.A spit of 8 µm thick is obtained. Corrosion resistance, measured in 1 by the same method as in Example 1, is 12 minutes.

Предлагаемый р аствор стабилен в работе. Шла|М по вл етс  после обработки 2,03 дм поверхности IB 1 л раствора.The proposed solution is stable in operation. Sla | M appears after treatment with 2.03 dm of IB surface with 1 liter of solution.

Очистка pacTiBOpa от шл.ама и последующа  корректировка по выработанным компонентам позвол ет продлить срок службы раCTBOipa до обработки 34 дм повархйости стальных |ИЗ делий.Cleaning the pacTiBOpa from the slab and subsequent adjustment of the components produced can extend the life of the raCTBOipa to the processing of 34 dm steel steel | IZ products.

Коррозионна  стойкость фосфатных- пленок , полученных из предлагаемого раствора, по мере его выработки уменьщаетс .The corrosion resistance of phosphate films obtained from the proposed solution decreases as it is produced.

Так, например, при фосфатированиИ 1 - 3 дм поверхности незажиренных образцов коррозионна  стойкость полученных пленок составл ет более 5 мин (до 14 м;ан), после фосфатировани  10,2 дм о«а равна 1,5-2 мин.So, for example, when phosphating 1–3 dm of the surface of unlubricated samples, the corrosion resistance of the films obtained is more than 5 minutes (up to 14 m; en), after phosphating 10.2 dm о and equals 1.5–2 min.

При обработке в 1 л раствора 6 дм поверхности зажиревных в масле МТ-16п стальных образцов коррозионна  стойкость -полученных фосфатных пленок составл ет 2,2-4 мип.When processing in 1 l of 6 dm solution of the surface of steel samples fatty in oil MT-16p, the corrosion resistance of the obtained phosphate films is 2.2-4 mip.
