Kufotokozera mwatsatanetsatane kwa graphite graphite (2)

1.4 Yachiwiri yogaya

Chotengera chimaphwanyidwa, pansi, ndikugwedezeka m'masamba a micrometers pafupifupi micrometers musanasakanizidwe. Amagwiritsidwa ntchito ngati zinthu zovuta, zotchedwa kukakamiza ufa. Zipangizo zamankhwala sekondale nthawi zambiri zimagwiritsa ntchito mphero yopukutira kapena mphero.

1.5 kupanga

Mosiyana ndi zopitilira muyeso ndikuumba,Inostatic Pressing Graphiteimapangidwa pogwiritsa ntchito ukadaulo wovuta kwambiri (Chithunzi 2). Dzazani ufa wosaphika mu khungu la rabani, ndikuyika ufa kudzera mu ufa wapamwamba kwambiri wamagetsi. Mutasindikizidwa, vatuum ufa ufa kuthira mpweya pakati pawo. Ikani mkati mwa chidebe chachikulu chomwe chili ndi masinthidwe amadzi monga madzi kapena mafuta, limbikizani mpaka 100-200mka, ndikuchikanitse mu cylindrical kapena mankhwala.

Malinga ndi mfundo ya Pascal, kukakamizidwa kumayikidwa nkhupu ya rabani kudzera mu madzi sing'anga monga madzi, ndipo kupsinjika ndikofanana mbali zonse. Mwanjira imeneyi, tinthu tating'onoting'ono tating'onoting'ono timakhala tikudzaza kudzazidwa ndi nkhungu, koma okakamizidwa makonzedwe osakhazikika. Chifukwa chake, ngakhale graphite ndi anisotropic mu kristalographgraphgraphgraphgraphgraphgraphgraphgraphgraphgraphgraphgraphgraphgraphgragragraphgragrance, yoyeserera yoyeserera ndi Isotropic. Zogulitsa zokhazokha sizingokhala mawonekedwe a cylindrical komanso makona, komanso mawonekedwe a cylindrical ndi mawonekedwe owopa.

Makina osindikizira a Inostatic amagwiritsidwa ntchito makamaka mu ufa wa ufa wa ufa. Chifukwa cha kuchuluka kwa mafakitale otha kwambiri monga Aerospace, mafakitale anyukiliya, ma entrol elestromagnatic apamwamba, ndipo amatha kuvina kwa nthawi yayitali ya 3000mm, komanso kukakamizidwa kwakukulu kwa 600mm. Pakadali pano, njira yayikulu kwambiri yosinthira makina ogwiritsira ntchito kaboni popanga graphite graphite ndi φ 2150mm × 4700mm, ndikugwira ntchito kwambiri ya 180mpa.

1.6 kuphika

Panthawi yowonjezera, mankhwala osokoneza bongo amachitika pakati pa ophatikizika ndi binder, zomwe zimapangitsa kuti biriger iwonongeke ndikumasula chinthu chophatikizika. Pakadutsa kutentha kochepa, malonda ophika akukula chifukwa chotenthedwa, komanso potenthetsa pambuyo pake, voliyumu imatsika chifukwa cha kuvomerezedwa.

Kukulirakulira kwa zopangidwazo, ndizovuta kwambiri kumasula chosinthika, ndipo pansi ndi mkati mwazomera zimakonda kutentha, kuwonjezeka kwa mafuta komanso kuphatikizika, komwe kungayambitse ming'alu yophika.

Chifukwa cha kapangidwe kake kabwino, kanikizana kanikizana kanikizani kumafunikira kuti azitha kuchedwa, ndipo kutentha mkati mwa ng'anjo kuyenera kukhala yunifolomu kwambiri, makamaka pa nthawi yotentha osasinthika komwe phula limatulutsidwa mwachangu. Njira yotentha iyenera kuchitika mosamala, ndikutenthetsa osatentha kuposa 1 ℃ / h ndi kutentha kutentha mkati mwa ng'anjo ya osakwana 20 ℃. Izi zimatenga pafupifupi miyezi 1-2.

1.7 Kusachedwa

Pakuwotcha, chinthu chosasunthika chosokoneza phula la malasha chimatulutsidwa. Ma Pores abwino amasiyidwa muzogulitsa potulutsa mpweya komanso kuchuluka kwa kuchuluka kwa magetsi, pafupifupi onse ndi pores.

Pofuna kukonza kachulukidwe kachulukitsa, mphamvu yamakina, yochititsa chidwi, mawonekedwe amafuta, njira yogwiritsira ntchito mankhwala, yomwe imaphatikizapo phula la phula likhoza kugwiritsidwa ntchito mkati mwa pores.

Choyambirira chiyenera kukhala preheate woyamba, kenako kadulidwe ndikuletsedwa mu thanki yopanda tanthauzo. Kenako, nyumba yosungunuka phula imawonjezeredwa ndi tanki yopanda tanthauzo ndipo inayang'aniridwa kuti alolere phula wosanjiriza kuti alowe mkati mwa chinthucho. Nthawi zambiri, chizolowezi chosindikizira chojambula chimadutsa nthawi zambiri zopanda tanthauzo.

1.8 graphitition

Tenthetsani mankhwala owerengera pafupifupi 3000 ℃℃℃

Njira zothandizira zimaphatikizapo njira zogwirira, njira zamkati zolumikizirana, njira zapamwamba kwambiri, etc. Miyezi yopangidwa ndi miyezi yambiri yogulitsa. Ng'anjo iliyonse imatha kugwira matani angapo kuti athe kupangira matani ambiri a zinthu zokazinga.
