Wannan yanayin yana ba da damar na'urorin lantarki na graphite don kiyaye daidaiton girma a cikin yanayin zafi mai zafi, rage fashewar damuwa da nakasar da ke haifar da haɓakar zafi.
3. Chemical kwanciyar hankali
Tsayin sinadarai na lantarki na graphite a cikin yanayin zafin jiki shima yana ɗaya daga cikin mahimman abubuwan da zasu iya jure yanayin zafi.
Juriya na Oxidation: A yanayin zafi mai yawa, ƙimar graphite tare da iskar oxygen yana da ɗan jinkiri, musamman a cikin iskar iskar gas ko rage yanayi, inda ƙimar oxidation na graphite ya fi ƙasa. Wannan juriya na iskar shaka yana ba da damar amfani da na'urorin lantarki na graphite na dogon lokaci a cikin yanayin zafi mai zafi ba tare da oxidized da lalacewa ba.
Juriya na lalata: Graphite yana da kyakkyawan juriya na lalata ga yawancin acid, alkalis da salts, wanda ke ba da damar lantarki na graphite su tsaya tsayin daka a cikin yanayi mai zafi da lalata. Misali, yayin aikin lantarki na aluminium, na'urorin lantarki na graphite na iya jure lalata narkakkar aluminum da gishirin fluoride.
4. Ƙarfin injina
Kodayake hulɗar tsakanin graphite tana da rauni sosai, ƙaƙƙarfan haɗin haɗin gwiwa a cikin tsarin sa na intramellar yana ba da graphite tare da ƙarfin injina.
Ƙarfin matsawa mai girma: Na'urorin lantarki na graphite na iya kula da ƙarfin matsawa ko da a yanayin zafi mai girma, mai iya jurewa babban matsin lamba da tasirin tasiri a cikin tanderun baka na lantarki.
Kyakkyawan juriya na zafi mai zafi: ƙarancin haɓakar haɓakar haɓakar thermal da haɓakar haɓakar thermal na graphite yana ba shi kyakkyawan juriya na zafin zafi, yana ba shi damar kiyaye amincin tsarin yayin saurin dumama da sanyaya tafiyar matakai da rage fashewa da lalacewa ta hanyar damuwa ta thermal.
5. Kayan lantarki
Ayyukan lantarki na graphite electrodes a cikin yanayin zafi mai zafi shima muhimmin dalili ne na aikace-aikacensu mai faɗi.
Ƙarfin wutar lantarki: Graphite yana da kyakkyawan halayen lantarki, wanda zai iya gudanar da aiki yadda ya kamata kuma ya rage asarar wutar lantarki. Wannan yanayin yana ba da damar graphite lantarki don canja wurin makamashin lantarki da kyau a cikin tanderun baka na lantarki da hanyoyin lantarki.
Low resistivity: Ƙananan juriya na graphite yana ba shi damar kula da ƙarancin juriya a yanayin zafi mai girma, rage haɓakar zafi da asarar makamashi, da inganta ingantaccen amfani da makamashi.
6. Gudanar da aiki
Ayyukan sarrafa na'urorin lantarki na graphite shima muhimmin abu ne don aikace-aikacen su a cikin yanayin zafi mai zafi.
Sauƙaƙan aiwatarwa: Graphite yana da kyakkyawan tsari kuma ana iya sarrafa shi cikin na'urori masu sifofi da girma dabam-dabam ta hanyar sarrafa injina, juyawa, niƙa da sauran dabaru don biyan buƙatun yanayin yanayin aikace-aikacen daban-daban.
Babban tsarki: Na'urorin lantarki masu ɗorewa masu tsabta suna da mafi kyawun kwanciyar hankali da aiki a cikin yanayin zafi mai zafi, wanda zai iya rage halayen sinadarai da lahani na tsari wanda ƙazanta suka haifar.
7. Misalai na Aikace-aikace
Ana amfani da na'urorin lantarki na graphite a ko'ina a cikin filayen masana'antu masu yawan zafin jiki. Wadannan su ne wasu misalan aikace-aikace na yau da kullun:
Electric Arc makera steelmaking: A cikin wutar lantarki Arc makera steelmaking tsari, graphite lantarki, kamar yadda conductive kayan, iya jure yanayin zafi har zuwa 3000 ° C, tana mayar da wutar lantarki zuwa thermal makamashi don narke guntun karfe da alade baƙin ƙarfe.
Electrolytic aluminum: A lokacin electrolytic aluminum tsari, da graphite lantarki hidima a matsayin anode, iya jurewa da high yanayin zafi da lalata narkakkar aluminum da fluoride salts, stably gudanar da halin yanzu, da kuma inganta electrolytic samar da aluminum.
Machining Electrochemical: A cikin injina na lantarki, graphite electrodes, a matsayin kayan lantarki na kayan aiki, na iya aiki da ƙarfi a cikin yanayin zafi mai zafi da ɓarna, samun ingantaccen aiki da samarwa.
Kammalawa
A ƙarshe, dalilin da yasa na'urorin lantarki na graphite zasu iya jure yanayin zafi mai zafi galibi ya ta'allaka ne a cikin tsarin su na musamman, kyawawan kaddarorin thermal, kwanciyar hankali sinadarai, ƙarfin injina, kaddarorin lantarki da aikin sarrafawa. Wadannan halaye suna ba da damar graphite lantarki su kasance barga da inganci a cikin yanayin zafi mai zafi da lalata, kuma ana amfani da su sosai a fagage kamar wutar lantarki tanderu steelmaking, electrolytic aluminum, da electrochemical aiki. Tare da ci gaba da ci gaban fasaha na masana'antu, aikin aiki da aikace-aikacen na'urorin lantarki na graphite za a kara fadada, samar da mafi aminci da ingantaccen mafita ga masana'antu masu zafi.
