Kufotokozera mwatsatanetsatane kwa graphite graphite (1)

Inostatic Pressing Graphitendi mtundu watsopano wa zojambulajambula zojambulajambula zomwe zapangidwa mu 1960s, zomwe zili ndi mndandanda wazinthu zabwino kwambiri. Mwachitsanzo, kuphatikizira kwa chilongako graphite kumakhala ndi kukana kwabwino kutentha. M'mlengalenga, mphamvu zake sizongotsika ndi kuwonjezeka kwa kutentha, komanso kumawonjezera, kufikira mtengo wake wapamwamba kwambiri pa 2500 ℃; Poyerekeza ndi graphite wamba, kapangidwe kake ndikwabwino ndi kwandiweyani, ndipo kufanana kwake ndikwabwino; Kuchulukitsa kwa kuwonjezeka kwa mafuta kumakhala kotsika kwambiri ndipo kumakhala ndi mkwiyo waukulu kwambiri; Isotropic; Kukana kwamphamvu kwamankhwala, kuchititsa chidwi ndi zamagetsi; Ali ndi magwiridwe antchito abwino kwambiri.

Ndizowona chifukwa cha ntchito yake yabwino kwambiri yomwe grafite yoyeserera inost imagwiritsidwa ntchito kwambiri m'minda monga menilllingo, chemistry, zamagetsi, ambo wama atomic, ndi ma atomic ener enimin. Kuphatikiza apo, ndi chitukuko cha sayansi ndi ukadaulo, magawo omwe amafunsira akukula nthawi zonse.

Kupanga Njira Za Adostic Preering Graphite

Kupanga njira yothandizira kwambiri graphite ikuwonetsedwa pa Chithunzi 1. Mwachidziwikire kuti kupanga kwa kafukufuku wa inostratic graphite ndi osiyana ndi elekisi ya graphite.

InostItic Preging Graphite imafunikira zida za isotropic zopangira, zomwe zimafunikira kukhala pansi mu ufa waluso. Kuchulukitsa kwa nthawi yayitali kupanga ukadaulo kumayenera kugwiritsidwa ntchito, ndipo kuzungulira kwake kumakula kwambiri. Kuti mukwaniritse kuchuluka kwake, kuphatikiza mitundu yambiri yowotcha kumafunikira, ndipo kuzungulira kwa plaphitition ndikotali kuposa imodzi ya graphite wamba.

Njira ina yopangira Grafite Graphite ndikugwiritsa ntchito mesophase ma micropheres am micropheres monga zopangira. Choyamba, kaboni micropher kaboni microphetion amagwirizanitsidwa ndi mankhwala okhazikika pa kutentha kwambiri, kenako ndikukakamizidwanso, kutsatiridwa ndi kuwerengedwa kwina ndi kukonzekera. Njirayi sinayambiridwe m'nkhaniyi.

1.1 zopangira

ThZida zopangira popanga Grafite Graphite zimaphatikizapo ma orgreates ndi omanga. Ogawika nthawi zambiri amapangidwa kuchokera ku mafuta a petroleum ndi asphalt coke, komanso maphala a phula nthaka. Mwachitsanzo, axf Get Isostaticati Idastiticati yopangidwa ndi Poco ku United States imapangidwa kuchokera ku asphalt asphalt coke Gilsonteontecoke.

Pofuna kusintha magwiridwe antchito molingana ndi kugwiritsa ntchito mosiyanasiyana, kaboni wakuda ndi wopanga amagwiritsidwanso ntchito ngati zowonjezera. Mwambiri, petroleum coke ndi asphalt coke amafunika kuwerengedwa pa 1200 ~ 1400 ℃ Kuchotsa chinyezi komanso kukhazikika nkhani musanagwiritse ntchito.

Komabe, pofuna kusintha makina opanga ndi kachulukidwe ka zinthu, pamakhala kupangapo mwachindunji kwa grafite graphite pogwiritsa ntchito zikwangwani monga coke. Makhalidwe opanga amakamba ndikuti muli ndi vuto la kusakhazikika, amangokhala ochimwa, ndikukula ndi ma cokenelchronorronorronly ndi binder coke. Bungwe nthawi zambiri limagwiritsa ntchito phula la malasha phula, ndipo malinga ndi zida zosiyanasiyana zam'manja ndi njira zomwe zimachitika mu bizinesi iliyonse, malo ofewetsa miyala ya malasha ogwiritsidwa ntchito kuyambira 50 mpaka 250 ℃.

Magwiridwe antchito a Inostatic Previter amakhudzidwa kwambiri ndi zida zopangira, ndipo kusankha kwa zinthu zopangira ndi ulalo wofunikira pakupanga zomaliza zomaliza. Musanadye, mawonekedwe ndi kufanana kwa zinthu zopangira ziyenera kusanthulidwa mosamala.

1.2 Kupera

Kukula kwa ophatikizika kwa grafite graphite nthawi zambiri kumafunikira kufikira panoamu. Pakadali pano, mawonekedwe ophatikizika kwambiri kwambiri ndi tinthu tating'onoting'ono ta 1 μ m. Ndiowonda kwambiri.

Kupera kuphatikiza mapangidwe a ufa wabwino chotere, Cruher yabwino kwambiri ya ultra ndi yofunika. Kupera ndi tinthu tating'onoting'ono kwa mthupi 10-0 μ kumafuna kugwiritsa ntchito mphero yopukutira kwa mpweya, kutalika kwa tinthu tambiri osakwana 10 μ kumafunikira kugwiritsa ntchito chopukusira mpweya.

1.3 kusakaniza ndikugwada

Ikani ufa wapansi ndi malawi phula Pambuyo podanda, chotsani phala ndikulizira.
