Hanyar hana flake graphite daga zama oxidized a babban zafin jiki

Don hana lalacewar lalacewa ta hanyar hadawan abu da iskar shaka na flake graphite a babban zafin jiki, dole ne a sami kayan da za a saka gashi a kan babban kayan zafin jiki, wanda zai iya kare graphite mai kyau yadda ya kamata daga iskar shaka a babban zafin jiki. Don nemo irin wannan nau'in flake graphite anti-oxidation gashi, dole ne mu fara samun wasu halaye kamar babban juriya na zafin jiki, ƙaƙƙarfan ƙarfi, kyakkyawan aikin rigakafin lalata, ƙarfin anti-oxidation mai ƙarfi da ƙarfi mai ƙarfi. Editocin graphite masu zuwa suna raba hanyoyin hanawaflake graphitedaga kasancewa oxidized a babban zafin jiki:

1. Yi amfani da kayan da tururi matsa lamba kasa da 0.1333MPa(1650 ℃) da kuma mai kyau m Properties.

2. Zaɓi kayan aikin gilashin da ya dace da buƙatun aikin a matsayin abin rufewa da kai, kuma ya sa ya zama abin rufewa na fashewa a yanayin aiki.

3. Dangane da aikin daidaitaccen makamashi na kyauta na amsawa tare da oxygen tare da zafin jiki, a zafin jiki na karfe (1650-1750 ℃), an zaɓi kayan da ke da alaƙa da oxygen fiye da carbon-oxygen don ɗaukar oxygen na farko, don haka kamar yadda su oxidize kansu da kuma kare daflake graphite. Ƙarar sabon lokaci da aka samar bayan iskar oxygen ya fi girma fiye da na farkon lokaci, wanda ke taimakawa wajen toshe tashar watsawar iskar oxygen da kuma samar da shingen oxidation.

4. A aiki zafin jiki, babban adadin inclusions kamar Al2O3, SiO2 da Fe2O3 a narkakkar karfe za a iya adsorbed, wanda amsa da kansu zuwa sinter, sabõda haka, daban-daban inclusions daga narkakkar karfe hankali shiga shafi.

Furuite graphite tunatar da mu cewa hadawan abu da iskar shaka zafin jiki na flake graphite a kasar Sin babban samar yankunan ne 560815 ℃ a lokacin da carbon abun ciki ne 88% 96% da barbashi size ne sama -400 raga. Daga cikin su, lokacin da barbashi girman graphite ne 0.0970.105mm, da hadawan abu da iskar shaka zafin jiki na graphite da fiye da 90% carbon abun ciki ne 600815 ℃ da na graphite da kasa da 90% carbon abun ciki ne 62075 ℃. Mafi crystallineflake graphiteshine, mafi girman yanayin zafi na oxidation, kuma ƙarancin asarar iskar shaka a babban zafin jiki shine.
