Description

Изобретение относитс об аоf дуговых и плазме но-дуговах убтройсгв, в частности в этих устройств.The invention relates to an arc arc and a plasma arc arc arc, in particular in these devices.
Швестный способ защити графвтизировавшос электродов njrreii пропйтйи их под давлением с 1ред9а тельным вакуумированивм водвым раствором зав твого вещества в смесЕ о борной кислотой не устран ет значитедь о окиол емооти элевтродов при ввоових тем1юратурах ..The well-known way to protect the graphite electrodes of a njrreii electrodes them under pressure with a rarefied evacuation with a water solution of a substance in a mixture of boric acid does not eliminate the meaning of oxide electromodes at two temperature ranges.
йредлараемый способ отжчаетс от известного тем, что, с целью зпменьшени о всд емости в вачестве зарщтного вещества используют KB LJ , причем проштву ведут при температуре 80-90 С под давлением 2-2,8 атм о предварительным аавуумированием п{иа давлении 1-2 мм рт.от.The proposed method is derived from the well-known fact that, in order to reduce the possibility of using a substance in the form of a substance, KB LJ is used, and the broth is carried out at a temperature of 80-90 ° C under a pressure of 2-2.8 atm. mm Hg
Обработ у электродов провод т водным раствором KBtJ Элевтроды , помещенные а автовдав, вцдешавак)т Х&-20 мин при давлении 1-2 Ш1 рт.ст. Затем автовлав заполн ют насыщенным .раствором о добаввой борной вислоты. Температура раствора 80-90 С. В автоклаве создаетс давление 2-2,8 атм Оосле 20-30 мин выдержки элевтхюды извлекают npOTHpiEiDT и оушат npi комнатной температуре в течении суток. П{щвес высушенных электродов составл ет 7-8 от первоначального веса.The treatment at the electrodes is carried out with an aqueous solution of KBtJ. Elevtrodes, placed at a pressure of 1-2 W1 Hg. Then the autoclave is filled with a saturated solution of boric acid addition. The temperature of the solution is 80-90 ° C. In a autoclave, a pressure of 2-2.8 atm is created. After 20-30 minutes of exposure, eleptyuds extract npOTHpiEiDT and dry npi to room temperature during the day. P {the weight of the dried electrodes is 7-8 of the initial weight.
