Hanyar hana flake graphite daga yin oxidizing a babban zafin jiki

Domin hana lalacewar tsatsa da iskar shaka ta flake graphite ke haifarwa a yanayin zafi mai yawa, ya zama dole a nemo kayan da za a sanya a kan kayan zafin jiki mai yawa, wanda zai iya kare flake graphite daga iskar shaka a yanayin zafi mai yawa. Domin samun irin wannan flake graphite anti-oxidation coat, dole ne mu fara tsayayya da yanayin zafi mai yawa da kuma ƙanƙantarsa.
Kyakkyawan juriya ga tsatsa, juriya ga tsatsa, juriya ga tsatsa, taurin kai da sauran halaye. Furuite Graphite Xiaobian mai zuwa ya gabatar da hanyoyin hana tsatsa daga tsatsa a yanayin zafi mai yawa:

1. Yi amfani da kayan da matsin tururin ƙasa da 0.1333MPa (1650*C) da kuma kyakkyawan aiki mai kyau.
2. Zaɓi kayan gilashin da ya cika buƙatun aiki a matsayin kayan rufe kai, kuma sanya shi ya zama kayan rufewa a zafin aiki.
3. Dangane da aikin daidaitaccen kuzarin da ake samu na amsawar iskar oxygen tare da zafin jiki, a zafin aikin ƙarfe (1650-1750*C), ana zaɓar kayan da suka fi kusanci da iskar oxygen fiye da iskar carbon-oxygen don ɗaukar iskar oxygen da kyau, don su yi oxidize kansu da kuma kare flake graphite. Bayan oxidation, ana samar da sabon mataki tare da rabon girma na matakin asali.
Babba, wanda ke taimakawa wajen toshe hanyar watsa iskar oxygen a cikin jiki da kuma samar da shingen iskar shaka.
4. A zafin aiki, ana iya haɗa adadi mai yawa na abubuwan da aka haɗa kamar Al2O3, SiO2 da Fe2O3 a cikin ƙarfe mai narkewa, waɗanda ke amsawa da kansu ga sintering, ta yadda abubuwa daban-daban daga ƙarfe mai narkewa a hankali ke shiga cikin rufin.
Zafin iskar shaka na flake graphite da aka samar a kasar Sin shine 560815°C lokacin da sinadarin carbon ya kai 88%96% kuma girman barbashi ya kai fiye da raga 400. Daga cikinsu, idan girman barbashi na graphite ya kai 0.0970.105mm, zafin iskar shaka na graphite mai dauke da sinadarin carbon fiye da kashi 90% shine 600815°C kuma sinadarin carbon bai kai kashi 90% ba.
Zafin iskar shaka na tawada shine 620790 C. Mafi kyawun graphite na crystalline shine, mafi girman zafin iskar shaka, kuma ƙarancin asarar nauyi na iskar shaka a babban zafin jiki.
