Description
При ТОЧНОЙ механической обработке детзотей изделий нз черных металлов необходима защита их от коррозии остатками доводочной пасты , пота рук рабочего, случайных загр знений и т. п., возникающих при межоперационном хранении обрабатываемых деталей.When EXACT machining of detoned products of ferrous metals, it is necessary to protect them from corrosion by residues of the finishing paste, the sweat of the hands of a worker, accidental contamination, etc., arising during the interoperative storage of the parts being processed.
Дл указанной цели наиболее пригодны летучие ингибиторы KODрозии .For this purpose, volatile inhibitors of KODrosia are most suitable.
Известен р д летучих ингибиторов коррозии, примен емых дл длительной консервации изделий из черных металлов, как например двухзамещенный фосфат аммони с нитритом натри и содой, уротропин илп мочевина с нитритом натри , бензоат аммони , углекислый моноэтаноламин и р д других.A number of volatile corrosion inhibitors are used for long-term preservation of ferrous products, such as disubstituted ammonium phosphate with sodium nitrite and soda, urotropine or urea with sodium nitrite, ammonium benzoate, carbonate monoethanolamine, and a number of others.
Практически эти ингибиторы примен ют, пропитыва ими бумагу.In practice, these inhibitors are used to soak the paper.
Одиако в услови х межоперационного хранени , в присутствии указанных выше загр знений, эффективность известиых ингибиторов ограничена , так как им свойственен р д общих недостатков. Важнейшимч из них вл ютс :However, under conditions of interoperative storage, in the presence of the above contaminants, the effectiveness of the lime inhibitors is limited, since they have a number of common drawbacks. The most important of these are:
1.Необходимость близкого контакта ингибитора с изделием, т. к., как правило, радиус действи ингибитора ограничен.1. The need for close contact of the inhibitor with the product, since, as a rule, the range of the inhibitor is limited.
2.Неспособность обеспечить полную защиту от коррозии деталей, на которых остаютс хлориды от йота рук, более чем на п ть суток и полна невозможность сохранить детали даже 30 мин ири действии большого количества хлоридов, например при увлажнении детали 3%-ным водиым раствором иовареиной соли.2. The inability to provide complete protection against corrosion of parts on which chlorides remain from iota hands is more than five days and it is completely impossible to save parts even for 30 minutes due to the large amount of chlorides, for example, when a part is moistened with 3% water solution of isoreva salt .
3.Необходимость завертывать каждую деталь в бумагу и мен ть ее каждые 10 дней.3. The need to wrap every detail in paper and change it every 10 days.
4.После удалени детали из сферы действи ингибитора поверхность металла подвергаетс коррозии, так же как и до воздействи ингибитора .4. After the part has been removed from the inhibitor's sphere of action, the metal surface is corroded, as well as prior to the effect of the inhibitor.
Предложен новый, свободный от вышеуказанных недостатков, способ межоперационной консервации изделий из черных металлов, заключаюшийс в том, что, с целью увеличени эффективиости консервации изделий, последние хран т в нарах водного раствора аммиака, вводимых в замкнутое пространство.A new, free from the above-mentioned deficiencies, method of inter-operational preservation of ferrous metal products has been proposed, which consists in the fact that, in order to increase the efficiency of preservation of products, the latter are stored in the bunks of an aqueous solution of ammonia introduced into the closed space.
