Kodi Rigid Graphite Felt ndi chiyani?

M'zaka zaposachedwapa, dziko la mafakitale lawona kugwiritsa ntchito kwambiri zipangizo zamakono zomwe zimapereka kulimba, mphamvu, komanso kukana kutentha. Pakati pa izi,graphite yolimba inamvekayakhala gawo lofunika kwambiri pa ntchito zosiyanasiyana, kuyambira kutenthetsa kutentha kwambiri mpaka njira zapadera zopangira.

Kodi Graphite Felt ndi chiyani?

Musanayambe kufufuza bwino za graphite yolimba, ndikofunikira kumvetsetsa kaye zomwe zimatsogolera, graphite feltGraphite felt ndi mtundu wa zinthu za kaboni zomwe zimapangidwa posintha mitundu yosiyanasiyana ya ulusi woyambira, monga rayon kapena polyacrylonitrile (PAN), kukhala zinthu zopangidwa ndi kaboni kudzera mu njira yotchedwa pyrolysis. Zotsatira zake zimakhala zinthu zofewa, zosinthasintha, komanso zopepuka zomwe zimasunga mawonekedwe a graphite oletsa kutentha kwambiri komanso owongolera kutentha.

Ngakhale kuti graphite felt imagwiritsidwa ntchito kwambiri m'mafakitale omwe amafuna kutentha kwambiri, monga m'mauvuni, m'mafakitale, kapena m'ma laboratories, kusinthasintha kwa zinthuzo kumalepheretsa kugwiritsidwa ntchito kwake ngati pakufunika kuuma. Apa ndi pomwe graphite felt yolimba imagwira ntchito.

Kodi Rigid Graphite Felt ndi chiyani?

Chovala cha graphite cholimba Imatchedwanso kuti graphite hard felt, ndi mtundu wosinthidwa wa graphite felt, wopangidwa kudzera mu njira zina zochiritsira ndi njira zowonjezera kuti uwonjezere kuuma kwake ndi kapangidwe kake. Mosiyana ndi ina yosinthasintha, graphite felt yolimba imasunga mawonekedwe ake pansi pa kupsinjika ndipo imatha kupirira mikhalidwe yovuta kwambiri yogwirira ntchito. Zipangizozo nthawi zambiri zimalowetsedwa kapena kukonzedwa ndi zinthu zomangira kapena ma resin omwe amathandizira kukulitsa kuuma kwake, kuonetsetsa kuti imasunga mawonekedwe olimba ngakhale ikakumana ndi kutentha kwambiri kapena mphamvu zamakanika.

Chovala cholimba cha graphite chimadziwika chifukwa chakukana kutentha kwambiri, kuyendetsa bwino kwambiri, komanso kulimba kwambiri, zomwe zimapangitsa kuti ikhale chinthu chabwino kwambiri m'mafakitale komwe kutentha ndi kupsinjika kwa makina ndizofunikira kwambiri.

Zinthu Zofunika Kwambiri za Filt Yolimba ya Graphite

1. Kukana Kutentha Kwambiri
   Chimodzi mwa zinthu zochititsa chidwi kwambiri za graphite yolimba ndi kuthekera kwake kupirira kutentha kwambiri popanda kutaya kapangidwe kake. Imatha kupirira kutentha mpaka 3,000°F (1,600°C), kutengera kapangidwe kake ndi njira yopangira. Izi zimapangitsa kuti ikhale chisankho chabwino kwambiri pakugwiritsa ntchito kutentha kwambiri, monga mu uvuni, ma reactor, kapena makina otenthetsera kutentha kwambiri.

2. Kutentha Kwambiri Kwambiri
   Graphite imadziwika chifukwa chakutentha kwabwino kwambiri, chomwe ndi chimodzi mwa zifukwa zomwe graphite yolimba imamvekera kukhala yofunika kwambiri m'mafakitale omwe amafuna kutentha koyenera. Kuchuluka kwa mphamvu ya graphite kumatsimikizira kuti kutentha kumagawidwa mofanana, kuchepetsa kutentha komanso kupewa malo otentha omwe angawononge zida kapena zinthu zomwe zimakhala zovuta.

3. Mphamvu ya Makina
   Chovala cholimba cha graphite chimapangidwa kuti chizitha kupirira kupsinjika kwa makina. Kulimba kwake kumachilola kuti chikhalebe ndi mawonekedwe ake ndi ntchito yake ngakhale chikakumana ndi mphamvu monga kupsinjika kapena kupsinjika. Kapangidwe kake kamapangitsa kuti chikhale chofunikira kwambiri pakugwiritsa ntchito komwe kulimba kwa zinthu ndikofunikira, monga kusefa mpweya ndi madzi, kapena ngati gawo la kapangidwe kake m'malo omwe ali ndi kuthamanga kwambiri.

4. Kusagwira Ntchito kwa Mankhwala
   Graphite felt ndi yolimba kwambiri ku mankhwala ambiri, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito m'malo okhala ndi mankhwala amphamvu. Siiwononga kapena kuwonongeka ikakumana ndi ma acid, alkali, kapena zosungunulira, zomwe zimawonjezera nthawi yake yogwirira ntchito komanso magwiridwe antchito m'mafakitale ambiri.

5. Wopepuka
   Ngakhale kuti ndi yolimba, graphite felt ndi yopepuka poyerekeza ndi zipangizo zina zomwe zimakhala ndi mphamvu zofanana ndi kutentha ndi makina. Izi zimapangitsa kuti zikhale zosavuta kuzigwiritsa ntchito ndikuziyika, komanso zimathandiza kuchepetsa kulemera konse kwa zida ndi zomangamanga zomwe zimagwiritsa ntchito.

Kugwiritsa Ntchito Rigid Graphite Felt

Kapangidwe kake ka graphite yolimba kamaipangitsa kukhala yosinthasintha kwambiri komanso yamtengo wapatali m'mafakitale ambiri. Zina mwa ntchito zofunika kwambiri ndi izi:

1. Kuteteza Kutentha Kwambiri

Chimodzi mwa zinthu zomwe zimagwiritsidwa ntchito kwambiri ndi graphite felt.kutchinjiriza kutenthaza uvuni, ma uvuni, ndi ma reactor. Kutha kwake kupirira kutentha kwambiri komanso kusunga mawonekedwe ake kumapangitsa kuti ikhale chinthu chabwino kwambiri chotetezera zida zofunika kwambiri m'mafakitale mongazitsulo, kupanga magalasindizoumbaumba.

2. Maselo a Mafuta

Graphite yolimba imagwiritsidwa ntchito nthawi zambiri muukadaulo wa maselo amafuta, makamaka mu ma cell amafuta a membrane osinthika ndi proton (PEMFCs). Kuchuluka kwa mphamvu yake komanso kukhazikika kwa kapangidwe kake pakatentha kumapangitsa kuti ikhale yofunikira kwambiri pakusunga magwiridwe antchito a maselo komanso kuonetsetsa kuti kutentha kumagawidwa bwino.

3. Zoteteza Kutentha ndi Zopinga za Kutentha

Mu mafakitale oyendetsa ndege, magalimoto, ndi mafakitale ena ogwira ntchito kwambiri, graphite felt yolimba imagwiritsidwa ntchito muzoteteza kutenthandizotchinga kutenthakuteteza zinthu zobisika ku kutentha kwambiri. Kaya ndi chombo chamlengalenga chomwe chikulowanso mumlengalenga wa Dziko Lapansi kapena makina otulutsa utsi m'magalimoto ogwira ntchito bwino, graphite yolimba imakhala ngati chotchinga chodalirika cholimbana ndi kutentha.

4. Zopangira Mankhwala

Chifukwa cha kusakhala ndi mankhwala komanso kukana dzimbiri, graphite felt yolimba imagwiritsidwa ntchito muma reactor a mankhwalazomwe zimagwira ntchito pansi pa mikhalidwe yovuta kwambiri. Zimathandiza kuteteza ndi kukhazikika kwa njira zotenthetsera kwambiri komanso kusunga kutentha koyenera nthawi zonse.

5. Mapulogalamu Ogwiritsa Ntchito Vacuum

In makina opumira mpweya, graphite yolimba imagwiritsidwa ntchito ngati chotetezera kutentha. Kupepuka kwake komanso kukana kutentha kwambiri kumapangitsa kuti ikhale yothandiza kusunga umphumphu wa zipinda zotsukira mpweya, kuonetsetsa kuti kutentha kumayendetsedwa bwino m'makina mongang'anjo zotsukira mpweya or malo osungira zinthu zobisikamatanki.
