Description

Примен емые способы защиты от кавитационного разрушени  деталей машин ИЛИ аппаратов, погруженных в жидкость, недостаточно эффективны, так как предохранительные пленки, создаваемые на поверхности деталей дл  этой цели, непрочны и быстро отслаиваютс .The applied methods of protection against cavitational destruction of machine parts OR apparatus immersed in a liquid are not sufficiently effective, since the protective films created on the surface of the parts for this purpose are fragile and quickly peel off.

Описываемый способ защиты металлов от кавитационного разрушени  более чем в три раза увеличивает их стойкость, вследствие того, что создаваемые предохранительные пленки прочно удерживаютс  на поверхности защищаемых деталей. Получение таких прочных пленок обеспечиваетс  введением в рабочую среду незначительных добавок органических веществ, причем предварительно может создаватьс  промежуточный ПОДСЛОЙ из других органических и при этом достаточно поверхностно-активных веществ. В качестве реагента, создающего защитную пленку, могут быть использованы ортооксахинолин, различные ксантогенатьп кали  и др., а также диэтилдитикарбонат натри , причем последний  вл етс  наиболее эффективным. В качестве реагентов, создающих ПОДСЛОЙ, могут примен тьс  сосновые масла, октиловый спирт, хинолиновые основани , керосин и другие новерхностно-активные вещества.The described method of protecting metals from cavitation destruction more than three times increases their durability, due to the fact that the protective films that are created are firmly held on the surface of the protected parts. The production of such strong films is ensured by the introduction into the working medium of minor additives of organic substances, and an intermediate SUBSTANCE from other organic substances can be created in advance and sufficiently surfactants are produced. As a reagent creating a protective film, orthoxachinoline, various potassium xanthanate, etc., as well as sodium diethyldithicarbonate can be used, the latter being the most effective. Pine oils, octyl alcohol, quinoline bases, kerosene and other surface active agents can be used as reagents.

В рабочую среду ввод тс  два или более веществ первой и второй групп в сумме не более 0,1% объема рабочей среды, например воды, растворов ИЛИ суспензий, в которой происходит работа защищаемых деталей.Two or more substances of the first and second groups are introduced into the working medium in the sum of not more than 0.1% of the volume of the working medium, for example, water, OR solutions of suspensions, in which the protected parts work.
