Mitundu ya Graphite Yapadera

graphite wapadera ndi mkulu chiyero, kachulukidwe mkulu ndi mphamvu mkulugraphitezakuthupi ndipo zimakhala ndi kukana kwa dzimbiri, kukhazikika kwa kutentha kwambiri komanso kuwongolera kwambiri kwamagetsi. Zimapangidwa ndi ma graphite achilengedwe kapena ochita kupanga pambuyo pa chithandizo cha kutentha kwa kutentha kwambiri komanso kuthamanga kwapamwamba kwambiri ndipo amagwiritsidwa ntchito kwambiri m'mafakitale pa kutentha kwakukulu, kuthamanga kwambiri komanso malo owononga.
Itha kugawidwa m'mitundu yosiyanasiyana kuphatikiza isostaticmatabwa a graphite, midadada ya graphite yotulutsidwa, kuumbidwamatabwa a graphitendi kunjenjemeramatabwa a graphite.

Manufacturing Technologies:

Graphitendi chinthu chapadera chomwe sichinali chitsulo chopangidwa ndi maatomu a carbon omwe amasanjidwa mu mawonekedwe a hexagonal lattice. Ndizinthu zofewa komanso zowonongeka zomwe zimagwiritsidwa ntchito popanga mafakitale osiyanasiyana chifukwa chapadera. Graphite imatha kukhalabe ndi mphamvu komanso kukhazikika ngakhale kutentha kopitilira 3600 ° C. Tsopano ndiroleni ndikuuzeni za kupanga graphite yapadera.

Isostatic graphite, yopangidwa ndi graphite yoyera kwambiri mwa kukanikiza, ndi chinthu chosasinthika chomwe chimagwiritsidwa ntchito popanga ng'anjo za kristalo imodzi, zitsulo zopitirirabe kuponya ma graphite crystallizers, ndi ma electrode a graphite a magetsi a spark discharge Machining. Kuphatikiza pa ntchito zazikuluzikuluzi, zimagwiritsidwa ntchito kwambiri m'magawo azitsulo zolimba (zowotcha ng'anjo ya vacuum, mbale za sintering, etc.), migodi (kupanga nkhungu zobowola), makampani opanga mankhwala (zosinthanitsa kutentha, mbali zosagwira dzimbiri), zitsulo (ma crucibles), ndi makina (makina zisindikizo).

Mfundo yaukadaulo waukadaulo wa isostatic idakhazikitsidwa ndi lamulo la Pascal. Imasintha kuponderezedwa kwa unidirectional (kapena bidirectional) kwa zinthuzo kukhala zopingasa zamitundumitundu (omnidirectional). Panthawiyi, ma carbon particles nthawi zonse amakhala osokonezeka, ndipo kuchuluka kwa voliyumu kumakhala kofanana ndi isotropic properties. Kupatula apo, sikutengera kutalika kwa chinthucho, motero kupangitsa kuti isostatic graphite ikhale yopanda kapena kusiyana pang'ono kwa magwiridwe antchito.
Kutengera kutentha komwe kupanga ndi kulimbitsa kumachitika, ukadaulo wa isostatic ukhoza kugawidwa kukhala kuzizira kwa isostatic, kutentha kwa isostatic, ndi kutentha kwa isostatic. Zida zosindikizira za Isostatic zimakhala ndi kachulukidwe kwambiri, nthawi zambiri 5% mpaka 15% kuposa zomwe zimapangidwa ndi nkhungu zapadziko lonse kapena zapawiri. Kachulukidwe wazinthu zosindikizira za isostatic amatha kufika 99.8% mpaka 99.09%.

Ma graphite owumbidwa ali ndi machitidwe odziwika bwino mu mphamvu zamakina, kukana kwa abrasion, kachulukidwe, kuuma komanso kuwongolera kwamagetsi ndipo machitidwewa amatha kupitilizidwa ndikuyika utomoni kapena chitsulo.
Kuumbidwa graphite mbali zabwino madutsidwe magetsi, kukana kutentha, kukana dzimbiri, chiyero mkulu, kudzikonda kondomu, kukana matenthedwe mantha ndi yosavuta mwatsatanetsatane Machining, ndipo chimagwiritsidwa ntchito m'madera mosalekeza kuponyera, aloyi molimba ndi pakompyuta kufa sintering, mphamvu ya magetsi, makina chisindikizo, etc.

Njira yowumba nthawi zambiri imagwiritsidwa ntchito popanga ma graphite ang'onoang'ono ozizira kapena zinthu zopangidwa mwaluso. Mfundo yake ndi kudzaza phala linalake mu nkhungu ya mawonekedwe ofunikira ndi kukula, ndiyeno gwiritsani ntchito kukakamiza kuchokera pamwamba kapena pansi. Nthawi zina, ikani kukakamiza kuchokera mbali zonse ziwiri kuti mukanikize phala kuti likhale mu nkhungu. Chogulitsa chomwe chatsitsidwa pang'onopang'ono chimatsitsidwa, kuziziritsidwa, kuyang'aniridwa, ndikuwunjika.
Pali makina omangira oyima komanso opingasa. Njira yakuumba nthawi zambiri imatha kusindikiza chinthu chimodzi nthawi imodzi, chifukwa chake imakhala ndi mphamvu zochepa zopanga. Komabe, imatha kupanga zinthu zolondola kwambiri zomwe sizingapangidwe ndi umisiri wina. Kuphatikiza apo, luso lopanga litha kupitilizidwa kukanikiza nthawi imodzi yamitundu ingapo ndi mizere yopangira makina.

Extruded graphite aumbike ndi kusakaniza mkulu chiyero graphite particles ndi binder ndiyeno extruding iwo mu extruder. Poyerekeza ndi isostatic graphite, ndi extruded graphite ali coarser njere kukula ndi mphamvu yochepa, koma ndi apamwamba matenthedwe ndi madutsidwe magetsi.
Pakalipano, zinthu zambiri za carbon ndi graphite zimapangidwa ndi njira ya extrusion. Amagwiritsidwa ntchito makamaka ngati zinthu zotenthetsera komanso zida zopangira matenthedwe munjira zochizira kutentha kwambiri. Kuphatikiza apo, midadada ya graphite itha kugwiritsidwanso ntchito ngati maelekitirodi kuti azitha kutengerapo njira za electrolysis. Chifukwa chake, amagwiritsidwa ntchito kwambiri ngati zisindikizo zamakina, zida zopangira matenthedwe ndi zida za elekitirodi m'malo ovuta kwambiri monga kutentha kwambiri, kuthamanga kwambiri, komanso kuthamanga kwambiri.

Njira ya extrusion ndikuyika phala mu silinda ya phala ya atolankhani ndikuyitulutsa. Atolankhani okonzeka ndi replaceable extrusion mphete (akhoza m'malo kusintha mawonekedwe mtanda gawo ndi kukula kwa mankhwala) pamaso pake, ndi zosunthika baffle amaperekedwa kutsogolo kwa mphete extrusion. Pulunger yayikulu yosindikizira ili kuseri kwa silinda ya phala.
Musanagwiritse ntchito kukakamiza, ikani chododometsa pamaso pa mphete yotulutsa, ndipo ikani kukakamiza kuchokera mbali ina kuti muphike phala. Pamene baffle imachotsedwa ndipo kukakamizidwa kumapitilizidwa kugwiritsidwa ntchito, phala limatulutsidwa kuchokera ku mphete ya extrusion. Dulani mzere wotuluka mu utali womwe mukufuna, kuziziritsa ndikuwunika musanawukidwe. Njira ya extrusion ndi njira yopitilira kupanga, zomwe zikutanthauza kuti pakatha kuchuluka kwa phala, zinthu zingapo (ma graphite, zida za graphite) zimatha kutulutsidwa mosalekeza.
Pakalipano, zinthu zambiri za carbon ndi graphite zimapangidwa ndi njira ya extrusion.

Ma graphite ogwedezeka ali ndi mawonekedwe ofanana ndi kukula kwambewu yapakati. Kupatula apo, imakhala yotchuka kwambiri chifukwa cha phulusa lake lochepa, mphamvu zamakina zowonjezera, komanso kukhazikika kwamagetsi ndi kutentha, ndipo imagwiritsidwa ntchito kwambiri pokonza zida zazikulu. Itha kulimbikitsidwanso pambuyo pa kulowetsedwa kwa utomoni kapena chithandizo cha anti-oxidation.
Amagwiritsidwa ntchito kwambiri ngati chotenthetsera & kutchinjiriza popanga ng'anjo za polysilicon ndi monocrystalline silicon mumakampani a photovoltaic. Amagwiritsidwanso ntchito kwambiri popanga ma hood otenthetsera, zinthu zosinthira kutentha, kusungunula ndi kuponyera zitsulo, kupanga ma n node omwe amagwiritsidwa ntchito popanga ma electrolytic, ndikupanga ma crucibles osungunula ndi alloying.

Mfundo yopangira graphite yogwedezeka ndikudzaza nkhungu ndi kusakaniza ngati phala, ndikuyika mbale yolemera kwambiri pamwamba pake. Mu sitepe yotsatira, zinthuzo zimaphatikizidwa ndi kugwedeza nkhungu. Poyerekeza ndi graphite yotulutsidwa, graphite yopangidwa ndi kugwedezeka ili ndi isotropy yapamwamba. mankhwala graphite amapangidwa ndi extrusion njira.
