Description
3 Коксовый «скелет легко разрушаетс после приложени нагрузки, не превышающей 0,1- 0,5 кг/см. Преимущество предлагаемого способа заключаетс в предотвращении спекани частиц, 5 исключении необходимости движени частиц, применении простых конструкций установок, сокращении расхода инертных газов, повышении скорости нанесени пленки пироуглерода. Предмет изобретени Способ нанесени на поверхность дисперсных огнеупорных частиц покрыти из пиро10 4 литического углерода, включающий продувку углеводородным газом дисперсных огнеупорных частиц, имеющих температуру 750- 1050°С, отличающийс тем, что, с целью предотвращени спекани дисперсных огнеупорных частиц, покрытых пиролитическим углеродом, перед продувкой углеводородным газом дисперсные огнеупорные частицы обрабатывают жидким углеводородсодержащим органическим материалом, например фенолформальдегидной смолой или мочевиноформальдегидной смолой, при температуре 900- 1200°С с последующим повышением температуры до 1300-1600°С.3 The coke skeleton is easily destroyed after a load is applied, not exceeding 0.1-0.5 kg / cm. The advantage of the proposed method is to prevent particles from sintering, 5 eliminating the need for particle movement, using simple plant designs, reducing the consumption of inert gases, increasing the rate of deposition of pyrocarbon film. Subject of the Invention A method of coating a pyroly 10 4 lytic carbon coating on a dispersed particles, including purging with a hydrocarbon gas of dispersed refractory particles having a temperature of 750-1050 ° C, characterized in that disperse refractory particles are treated with liquid hydrocarbon-containing organic material, for example, phenol-formaldehyde resin or ureas formaldehyde resin, at a temperature of 900-1200 ° C with a subsequent increase in temperature to 1300-1600 ° C.
