Igishushanyo cya Isostatike, bizwi kandi nka grafitike ya isostatike, bivuga uburyo aho uruvange rwibikoresho fatizo rushyirwa mubice byurukiramende cyangwa uruziga muri sisitemu yitwa gukonjesha isostatike (CIP). Gukonjesha ubukonje bwa isostatike nuburyo bwo gutunganya ibintu aho impinduka zumuvuduko wamazi afunze, adashobora kwangirika yanduza buri gice cyamazi, harimo nubuso bwikintu cyacyo.
Ugereranije nubundi buhanga nko gusohora no kunyeganyega, ikoranabuhanga rya CIP ritanga isotropic synthique grafite.Igishushanyo cya Isostatikemubisanzwe kandi ifite ingano ntoya ya grafite ya syntetique (hafi microni 20).
Gukora inzira ya isostatike grafite
Gukanda Isostatike ni ibyiciro byinshi byemerera kubona ibice bimwe cyane hamwe nibintu bihoraho bifatika mubice byose.
Imiterere isanzwe ya isostatike grafite:
• Ubushyuhe bukabije hamwe no kurwanya imiti
• Kurwanya ubushyuhe bwiza cyane
• Amashanyarazi menshi
• Amashanyarazi menshi
• Yongera imbaraga hamwe no kongera ubushyuhe
• Biroroshye gutunganya
• Irashobora kubyazwa umusaruro mwinshi cyane (<5 ppm)
Gukoraigishushanyo mbonera
1. Kokiya
Kokiya nikintu cyakozwe munganda zamavuta mugushyushya amakara akomeye (600-1200 ° C). Inzira ikorerwa mu ziko ryabugenewe byabugenewe hakoreshejwe imyuka yaka hamwe na ogisijeni nkeya. Ifite agaciro gakomeye kuruta amakara asanzwe.
2. Kumenagura
Nyuma yo kugenzura ibikoresho bibisi, byajanjaguwe kugeza mubunini runaka. Imashini zidasanzwe zo gusya ibikoresho byohereza ifu nziza yamakara yabonetse mumifuka idasanzwe hanyuma ukayishyira muburyo ukurikije ingano.
Ikibanza
Nibicuruzwa byokunywa amakara akomeye, ni ukuvuga gutwika 1000-1200 ° C nta mwuka. Ikibanza ni amazi yumukara mwinshi.
3. Gupfukama
Nyuma yo gusya kokiya birangiye, bivangwa n'ikibanza. Ibikoresho byibanze byombi bivangwa nubushyuhe bwo hejuru kugirango amakara ashobore gushonga kandi ahuze nuduce twa kokiya.
4. Impanuka ya kabiri
Nyuma yo kuvanga, hashyizweho imipira mito ya karubone, igomba kongera kuba hasi kugeza ibice byiza cyane.
5. Gukanda
Iyo ibice byiza byubunini busabwa bimaze gutegurwa, icyiciro cyo gukurikira kirakurikira. Ifu yabonetse ishyirwa mubibumbano binini, ibipimo byayo bihuye nubunini bwa nyuma. Ifu ya karubone mubibumbano ihura numuvuduko mwinshi (MPa zirenga 150 MPa), ikoresha imbaraga nigitutu kimwe mubice, ikabitondekanya muburyo bumwe bityo bikagabanywa. Ubu buryo butuma tubona ibipimo bimwe bya grafite muburyo bwose.
6. Carbone
Icyiciro gikurikira kandi kirekire (amezi 2-3) ni uguteka mu itanura. Ibikoresho bikandamijwe byashyizwe mu itanura rinini, aho ubushyuhe bugera kuri 1000 ° C. Kugira ngo wirinde inenge cyangwa ibice, ubushyuhe mu itanura burahora bugenzurwa. Nyuma yo guteka birangiye, igihagararo kigera kubikenewe.
7. Gutera inda
Kuri iki cyiciro, blok irashobora kwinjizwa mukibanza hanyuma ikongera gutwikwa kugirango igabanye ubukana bwayo. Gutwita mubisanzwe bikorwa hamwe n'ikibanza gifite ubukonje buke ugereranije n'ikibanza gikoreshwa nka binder. Ubukonje bwo hasi burasabwa kuzuza icyuho neza.
8. Igishushanyo
Kuri iki cyiciro, matrix ya atome ya karubone yarategetswe kandi inzira yo guhindura kuva karubone ikagera kuri grafite yitwa grafite. Graphitisation ni ubushyuhe bwa blok yakozwe kugeza ku bushyuhe bwa 3000 ° C. Nyuma yo gushushanya, ubucucike, amashanyarazi, amashanyarazi hamwe no kurwanya ruswa byateye imbere cyane, kandi imikorere yo gutunganya nayo iratera imbere.
9. Ibikoresho bishushanyije
Nyuma yo gushushanya, ibintu byose bya grafite bigomba kugenzurwa - harimo ingano, ingano, kunama no gukomera.
10. Gutunganya
Ibikoresho bimaze gutegurwa neza no kugenzurwa, birashobora gukorwa ukurikije inyandiko zabakiriya.
11. Kwezwa
Niba igishushanyo cya isostatike gikoreshwa muri semiconductor, silicon imwe ya kirisiti hamwe ninganda zitanga ingufu za kirimbuzi, birasabwa kugira isuku nyinshi, bityo umwanda wose ugomba kuvanwaho hakoreshejwe imiti. Imyitozo isanzwe yo gukuraho umwanda wa grafite nugushira ibicuruzwa bishushanyije muri gaze ya halogene hanyuma ukabishyushya kugeza kuri 2000 ° C.
12. Kuvura hejuru
Ukurikije ikoreshwa rya grafite, ubuso bwayo burashobora kuba hasi kandi bukagira ubuso bunoze.
13. Kohereza
Nyuma yo gutunganyirizwa bwa nyuma, ibisobanuro bya grafite byuzuye birapakirwa kandi byoherejwe kubakiriya.
Kubindi bisobanuro kubunini buboneka, amanota ya isostatike ya grafite nibiciro, nyamuneka twandikire. Ba injeniyeri bacu bazishimira kukugira inama kubikoresho bikwiye no gusubiza ibibazo byawe byose.
