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 irin flake graphite anti-hadawan abu da iskar shaka gashi, dole ne mu fara tsayayya high zafin jiki da compactness.
Good, mai kyau lalata juriya, mai karfi hadawan abu da iskar shaka juriya, high taurin da sauran halaye. Furuite Graphite Xiaobian mai zuwa yana gabatar da hanyoyin hana graphite oxidized a babban zafin jiki:

1. Yi amfani da kayan da tururi matsa lamba kasa da 0.1333MPa(1650*C) da kuma mai kyau m yi.
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 * C), an zaɓi kayan da ke da alaƙa da oxygen fiye da carbon-oxygen don fi son kama oxygen, don haka kamar yadda oxidize kansu da kuma kare flake graphite. Bayan hadawan abu da iskar shaka, wani sabon lokaci tare da girman rabo na lokaci na asali ana haifar da shi.
Babban, wanda ke taimakawa don toshe tashar watsawar iskar oxygen da samar da shingen iskar oxygen.
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.
A hadawan abu da iskar shaka zafin jiki na flake graphite samar a kasar Sin ne 560815 ° C lokacin da carbon abun ciki ne 88%96% da barbashi size ne fiye da 400 meshes. 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 ° C da carbon abun ciki ne kasa da 90%.
A hadawan abu da iskar shaka zafin jiki na tawada ne 620790 C. Mafi kyaun crystalline flake graphite shi ne, mafi girma da hadawan abu da iskar shaka ganiya zafin jiki ne, da ƙasa da hadawan abu da iskar shaka nauyi asara ne a high zafin jiki.
