Description
новы и пропитывают одним из указанных элементоорганических соединений или его гидролиэатом, которые предварительно смешивают с тонкодисперсными наполнител. ми - AE.O, или МдО, ил ыог , или АЕ . Термюобработку про питанного издели провод т при температуре , котора определ етс видом используемого наполнител . При этом в порах издели осаждаетс соответствующий полидисперсный окисел, снижающий доступ кислорода к графиту.are new and are impregnated with one of the indicated organometallic compounds or its hydrolyzate, which are pre-mixed with finely dispersed filler. mi - AE.O, or MDO, il yog, or AE. The heat treatment of the fed product is carried out at a temperature that is determined by the type of filler used. At the same time, the corresponding polydisperse oxide is deposited in the pores of the product, which reduces the access of oxygen to graphite.
Пример. Защите от окислени подвергают электроды, извлеченные из проема перекрыти после остановки ванны. Частично окисленные блоки зачищают до твердой основы, пропитывают тетраэтоксисиланом,а затем гидролизатом на его основе, приготовленным следующим образом:, к 10 л тетраэтоксисилана приливают при интенсивном переманивании 4,5л 85%-ного этанола, 1,5 л воды, 0,5-1,0 мл концентрированной фосфорной кислоты и 60% тонкодисперсного кварца с размером зерен б мкм. Обработанные таким Образом электроды подвергают термообработке при 700-800 с.Example. Electrodes extracted from the overlap opening after stopping the bath are protected against oxidation. Partially oxidized blocks are cleaned to a solid base, impregnated with tetraethoxysilane, and then with a hydrolyzate based on it, prepared as follows: to 10 l of tetraethoxysilane is poured with intensive poaching of 4.5 liters of 85% ethanol, 1.5 liters of water, 0.5- 1.0 ml of concentrated phosphoric acid and 60% finely divided quartz with a grain size of b microns. The electrodes treated in this way are subjected to heat treatment at 700-800 s.
Защищенные электроды, установленные в работающие ванны, работают достаточно эффективно.The protected electrodes installed in the working baths work quite effectively.
Предлагаемый способ в сравнении с известными обеспечивает более полное заполнение пор образующегос при термодеструкции окисла, так как содержание его в элементоорганическом 1соединении выше, чем в растворе кремнийорганического полимера. Это позвол ет увеличить стойкость восстановленного анода, снизить затраты на пропитку в 5-10 раз.The proposed method, in comparison with the known ones, provides a more complete filling of the pores formed during the thermal decomposition of the oxide, since its content in the organoelement compound is higher than in the solution of the organosilicon polymer. This makes it possible to increase the durability of the reconstituted anode, to reduce the cost of impregnation by 5-10 times.
