Description
Предлагаетс применить в качестве ингибитора дл травлени стали сульфонат натри СН, представл ющий собой смесь натриевых солей сульфоновых кислот жирного р да RSOsNa, где R-радикал нормального строени из 12-18 атомов углерода. Сульфонат натри СН хорошо растворим в воде и кислотах . Он вноситс в раствор серной кислоты в количестве 0,1%.It is proposed to use sodium sulfonate as an inhibitor for steel etching, which is a mixture of sodium salts of sulfonic acids of the fatty series RSOsNa, where the R-radical is of normal structure of 12-18 carbon atoms. Sodium sulfonate CH is highly soluble in water and acids. It is added to the sulfuric acid solution in an amount of 0.1%.
Состав предлагаемого технического сульфоната следующир.The composition of the proposed technical sulfonate following.
Содержание натриевых солей - не менее 88%; не омыл емых- 1,5%; поваренной соли-не более 7,0%; воды-не более 2,0/о; железа-не более 0,05% и других примесей- около l,5Vo.The content of sodium salts is not less than 88%; not washed, 1.5%; salt-not more than 7.0%; water is not more than 2.0 / o; iron is not more than 0.05% and other impurities are about l, 5Vo.
Опыты показали, что сульфонат натри обладает в два-три раза большим ингибиторным действием, но сравнению с присадкой ЧМ. Применение сульфоната натри в качестве нрисадки дл травлени стали позвол ет увеличить скорость травлени на 10-20%, но сравнению со временем, требующимс дл травлени с присадкой ЧМ.Experiments have shown that sodium sulfonate has two to three times more inhibitory effect, but compared with the additive FM. The use of sodium sulphonate as a risk to pickle steel makes it possible to increase the pickling rate by 10-20%, but compared to the time required for pickling with an FM additive.
При этом установлено, что замена нрисадки ЧМ присадкой сульфоната натри почти полностью устран ет недотрав, и производительность травильного цеха может быть повышена.At the same time, it was found that the replacement of the FM risk by the sodium sulfonate additive almost completely eliminates undertraining, and the productivity of the pickling plant can be improved.
Положительным фактором вл етс также то, что в отличие от нрисадка ЧМ сульфонат натри не дает никаких загр знений. Это облегчает контроль за процессом производства и позвол ет широко примен ть полученный из отработанного травильного раствора незагр зненный железный купорос.It is also a positive factor that, in contrast to the risk of FM, sodium sulfonate does not cause any contamination. This facilitates the control of the production process and makes it possible to widely apply the non-contaminated iron sulphate obtained from the spent pickling solution.
Предмет изобретени Subject invention
Способ травлени стали в ингнбиторных растворах на основе сульфокислот , отличающийс тем, что, с целью повышени качества травлени , в травильный раствор серной кислоты добавл ют в количестве 0,1% сульфонат натри , имеюший состав: натриевых солей - не менее 88%; не омыл емых - 1,5%; поваренной соли - не более 7,0°/о; воды -не более 2,0%; железа-не более 0,05% и другихпримесей около 1,.The method of steel etching in sulfite-based innbitor solutions, characterized in that, in order to improve the quality of etching, 0.1% sodium sulfonate having the composition of: sodium salts - at least 88% is added to the etching solution of sulfuric acid; not washed - 1.5%; salt - not more than 7.0 ° / o; water is not more than 2.0%; iron is not more than 0.05% and other impurities about 1 ,.
