Description
Известные способы изготовлени травильных присадок к черным металлам с применением пиридиновых оснований не обеспечивают необходимых свойств присадок, например, тормоз щее действие присадок недостаточно, и это ограничивает их практическое применение в качестве ингибиторов.The known methods of making pickling additives for ferrous metals with the use of pyridine bases do not provide the necessary properties of additives, for example, the inhibitory effect of the additives is not enough, and this limits their practical use as inhibitors.
Описываемый способ изготовлени травильных присадок увеличивает их защитное действие и тем самым повыщает качество обработанной продукции.The described method of making pickling additives enhances their protective action and thus improves the quality of the processed product.
Способ изготовлени травильных присадок з ключаетс в следующем .The method for making pickling additives is as follows.
Пиридиновые основани освобождаютс от воды и подкисл ютс серной или сол ной кислотой до сно выраженной кислой реакции на лакмус. Затем они нагреваютс до 60-70 и при интенсивном размеП1ивании в них вводитс соль висмута в количестве 0,05-0,01%.Pyridine bases are freed from water and acidified with sulfuric or hydrochloric acid to a clearly pronounced acid reaction to litmus. Then they are heated to 60-70 and, with intensive spacing, bismuth salt is introduced into them in an amount of 0.05-0.01%.
В зависимости от состава травильных ванн в них рекомендуетс вводить:Depending on the composition of the pickling baths, it is recommended to introduce into them:
при сернокислотных - хлористый висмут, а при сол нокислотных - сернокислый висмут.with sulfuric acid, bismuth chloride; and with hydrochloric acids, bismuth sulfate.
Изготовленные описанным способом травильные ирисадки унеличмвают их защитное действие приблизительно в 20 раз.The etching irises produced as described above increase their protective action approximately 20 times.
Предмет изобретени Subject invention
Способ изготовлени травильной присадки из пиридиновых оснований , отличающийс тем, что к ним в качестве активатора добавл ют при нагревании соли висмута в количестве 0,05-0.01%.A method of making an etching additive from pyridine bases, characterized in that the bismuth salt in an amount of 0.05-0.01% is added to them as an activator.
