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

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.
