Description
Известно применение антраценового масла дл защиты металла от коррозии при травлении кислотой.It is known to use anthracene oil to protect a metal from corrosion by acid etching.
Незначительный эффект в смысле сннжени коррозни достигаетс при присадке к питательной воде некоторых органических коллоидов, например танннна, дубового экстракта. Последний вл етс уннверсальны .м средством дл борьбы с коррозией паровозных котлов. Однако действие его недостаточно и котельна коррози вл етс бичом дл многих паровозов, работающих на участках, где вода содержит в большом количестве хлориды.A slight effect in terms of corrosion is achieved when some organic colloids, such as tannna, oak extract, are added to the feed water. The latter is an unversion. It is a means for combating the corrosion of locomotive boilers. However, its action is insufficient and boiler room corrosion is a scourge for many locomotives operating in areas where water contains a large amount of chlorides.
Успещно борютс с коррозиен, где возгаожио, путем примеиени ингибиторов при комиатной температуре (кислотное травление, промывка и т. п.). Дл этой целп служат некоторые алкалоиды. Однако в услови х парового котла органпческие вещества, вследствие высокнхЧемператур , в значительной степенлг разрушаютс и утрачивают свою 1нгибирующую способность.Successfully struggling with corrosion, where possible, by applying inhibitors at a comet temperature (acid etching, rinsing, etc.). For this purpose, some alkaloids serve. However, under conditions of a steam boiler, organics, due to high temperatures, are largely destroyed and lose their inhibition capacity.
Отличительна особен1:ость описываемого способа заключаетс в том, что в качестве ингибирующего средства примен ют водную эмульсию антраценового масла и тринатрийфосфата или едкого натра с примерным соот ющенисм 1 : 2.A distinctive feature1: the method described is that an aqueous emulsion of anthracene oil and trisodium phosphate or caustic soda with an approximate ratio of 1: 2 is used as an inhibiting agent.
Предохранение откоррознн котлов низкого переднего давлени но описываемому способу осуществл ;ют следующим образом.The prevention of the corrosion of the low front pressure boilers but described in this way is carried out as follows.
Антраценовое масло добавл ют к и}1тательной воде в виде эмульсии . Дл получени этойэмульспи в барабан емкостью 20-25 л, с механической мешалкой, ввод т рассчитанное количество антраценового масла (10 г на тонну воды), необходимое количество раствора едкого натра 20 г на тонну воды) нлн тринатрийфосфата и доливают до определенного объема гор чей водой. Барабан герметически закрывают и включают мешалку, перемешивание про1 звод т 10-15 мин.Anthracene oil is added to and} body water in the form of an emulsion. To obtain this emulsion, a calculated amount of anthracene oil (10 g per ton of water), the required amount of caustic soda 20 g per ton of water) nl of trisodium phosphate are added to a drum with a capacity of 20-25 liters, with a mechanical stirrer, and topped up with a certain amount of hot water. . The drum is sealed and the stirrer is turned on, stirring is carried out for 10-15 minutes.

Предмет изобретени Subject invention
Способ предохранени от крррозии паровых котлов низкого и среднего давлени путем добавлени к питательной воде ингибируюших средств, отличающийс тем, что в качестве ингибирующего средства примен ют водную эмульсию антраценового масла и тринатрийфосфата или едкого натра с примерным соотношением 1:2,The method of preventing the crushing of low and medium pressure steam boilers by adding inhibiting agents to the feed water, characterized in that an aqueous emulsion of anthracene oil and trisodium phosphate or caustic soda with an approximate ratio of 1: 2 is used as an inhibiting agent,
