Description
Известно, что совместное действие высоких температур (300- 500°) и давлений. (100-300 атм) вызывает усиленную коррозию конструкционных материалов. Однако вскрытие механизма коррозионных процессов при критических параметрах затруднено ввиду отсутстви удовлетворительных методов и аппаратуры дл измерени электродното потенциала и сн ти пол ризационных кривых.It is known that the combined action of high temperatures (300-500 °) and pressures. (100-300 atm) causes increased corrosion of structural materials. However, the opening of the mechanism of corrosion processes at critical parameters is difficult due to the lack of satisfactory methods and equipment for measuring electrical potential and removing polarization curves.
Основна трудность измерени электрохимических характеристик заключаетс в том, что не -представл етс возможным определить потенциал электрода сравнени , помещенного в автоклав и наход щегос при высоких температуре и давлении, по отношению к какому-либо стандартному электроду, наход щемус -при обычных температуре и давлении.The main difficulty in measuring the electrochemical characteristics is that it is not possible to determine the potential of a reference electrode placed in an autoclave and located at high temperature and pressure relative to any standard electrode located at ordinary temperature and pressure.
Описываемый электролитический ключ, выполненный в виде гильзы с контактирующим узлом и каломельным э.чектродом в качестве электрода сравнени , позвол ет устранить отмеченные трудности и проводить измерени потенциала электрода непосредственно в автоклаве . С этой целью контактирующий узел выполнен в виде стержн , например, из дерева, пропитанного исследуемым раствором.The described electrolytic key, made in the form of a sleeve with a contacting node and a calomel electrode as a reference electrode, makes it possible to eliminate the noted difficulties and to measure the potential of the electrode directly in an autoclave. To this end, the contacting node is made in the form of a rod, for example, from wood, impregnated with the test solution.
На чертеже изображена схема автоклава с установленным на нем электролитическим ключом.The drawing shows a diagram of an autoclave with an electrolytic key installed on it.
Контактирующий узел электролитического ключа представл ет собой пропитанный испытуемым раствором дерев нный стержень /, обеспечивающий электролитический контакт и герметичность автоклава , состо щего из корпуса 2 и крышки 5.The electrolytic key contacting unit is a wooden rod / impregnated with the test solution, providing electrolytic contact and leak tightness of an autoclave consisting of body 2 and cover 5.
Стержень / вставлен в ниппель 4. Ниппель 4, трубка 5 и наконечник 6, к которому с помощью стекл нного ключа присоедин етс каломельный электрод в качестве электрода сравнени , изготовленыThe rod / is inserted into the nipple 4. The nipple 4, tube 5 and tip 6, to which a calomel electrode is attached as a reference electrode with a glass key, are made
