Takaddun hoto, azaman babban aikin hatimin aiki da kayan aikin zafi, yana taka muhimmiyar rawa a cikin sinadarai na petrochemical, wuta, sararin samaniya, da sauran filayen. Babban juriyar yanayin zafi na musamman -, daidaiton sinadarai, da kai{3}} kayan shafawa sun sa ya zama madaidaicin madadin ƙarfe na gargajiya ko fakitin polymer. Wannan labarin zai bincika ainihin fa'idodin fasaha na tattarawar graphite da mafita na aikace-aikace na yau da kullun.
I. Fa'idodin Aiki na Shirya Graphite
Halitta graphite flake, ta hanyar aiki na musamman, za'a iya canza shi zuwa faɗaɗɗen graphite ko sassauƙan zane mai sassauƙa tare da tsari mai faɗi. Wannan kayan yana kula da kewayon zafin jiki mai faɗi na -200 zuwa digiri 600 a cikin yanayin oxidizing kuma ba shi da ƙarfi ga yawancin kafofin watsa labarai na acidic da alkaline. Idan aka kwatanta da na gargajiya asbestos ko polytetrafluoroethylene shiryawa (PTFE), graphite shiryarwa yana da ƙananan coefficient na gogayya (kimanin 0.1-0.15), yadda ya kamata rage lalacewa a kan sealing saman a inji kayan aiki. Bugu da ƙari kuma, da thermal watsin iya isa 100-150 W / (m · K), samar da zafi dissipation a tsauri sealing aikace-aikace da kuma muhimmanci inganta tsarin AMINCI.
II. Yanayin Aikace-aikace na Musamman da Magani
1. Babban -Tsarin Hatimin Matsi
A cikin babban ma'aunin wutar lantarki mai tsananin zafi, ana amfani da zoben da aka siyar da graphite da yawa tare da ƙarfafa wayan nickel don jure matsin lamba MPa 45 da cimma ruwa. Ƙirar matsi na kashi 30% -50% na damuwa na shigarwa na farko yana ramawa don ɗaukar hutun da ya haifar da aiki na dogon lokaci.
2. Chemical Pump Shaft Seal ingantawa
Don kafofin watsa labarai masu lalata sosai (kamar sulfuric acid da aka tattara da kuma hydrofluoric acid), an ɓullo da ingantaccen tattarawar graphite fiber, yana ƙara ƙarfin ƙarfinsa zuwa sama da MPa 12. Haɗe da allura -nau'in tsarin lubrication na hatimi, ana iya tsawaita tazarar kulawa da fiye da sau uku na hanyoyin gargajiya.
3. Babban - Kayan Aikin Musanya Zafin Zafi
A cikin tsarin ajiyar zafi na gishiri mai narkewa, faɗaɗɗen graphite da haɗaɗɗen haɗaɗɗen silicon carbide suna tabbatar da aikin rufewa a yanayin zafi sama da digiri 300 yayin da rage asarar zafi da 15% -20% godiya ga kyakkyawan ingancin yanayin zafi na graphite.
III. Abubuwan Ci gaban Fasaha
Binciken na yanzu yana mai da hankali kan nano{0} fasaha na gyarawa, kamar ƙari na molybdenum disulfide (MoS₂) ko graphene, don ƙara haɓaka juriya na filler da haɓakar zafi. Bugu da ƙari, bugu na 3D na tsarin gyaran gyare-gyare na musamman a halin yanzu yana cikin lokacin matukin jirgi, yana ba da damar hatimi daidai a ƙarƙashin yanayin aiki mai rikitarwa.
Maganganun filler na Graphite, ta hanyar sabbin abubuwa da haɓaka aikin injiniya, suna ci gaba da haɓaka haɓaka masana'antu zuwa ingantaccen inganci, aminci, da tsawon rai. Tare da karuwar buƙatun masana'anta kore, ƙarancin -sulfur, fasahar sarrafa hoto mai dacewa da muhalli kuma za ta zama babban yanki na ci gaba a cikin masana'antar.
