I-graphite ecindezelwe yi-Isostaticuhlobo olusha lwe-graphite material, olunokusebenza okuhle kakhulu kukagesi, ukumelana nokushisa okuphezulu kanye nokuzinza kwamakhemikhali, ngakho-ke isetshenziswa kabanzi emikhakheni eminingi yobuchwepheshe obuphezulu.Leli phepha lizokwethula ngokuningiliziwe inqubo yokukhiqiza, ukusetshenziswa okuyinhloko kanye nentuthuko yesikhathi esizayoi-graphite ecindezelwe isostatic.
Inqubo yokukhiqiza yei-graphite ecindezelwe isostatic
Inqubo yokukhiqiza ye-isostatic graphite ikakhulukazi ihlanganisa lezi zinyathelo ezilandelayo:
1. Ukulungiswa kwempahla eluhlaza: Impahla ye-graphite ecindezelwe ye-isostatic ihlanganisa i-aggregate ne-binder.I-aggregate ngokuvamile yenziwe nge-petroleum coke noma i-asphalt coke, edinga ukubalwa ku-1200 ~ 1400℃ ukuze kususwe umswakama kanye nokuguquguquka ngaphambi kokuthi kusetshenziswe.I-binder yenziwe nge-coal pitch noma i-petroleum pitch, enwebekayo futhi inkontileka ngokuhambisana ne-aggregate ukuqinisekisa i-isotropy yento.
2. Ukugaya: Izinto ezingavuthiwe zigaywa zibe impushana ecolekile, ngokuvamile edinga usayizi wesamba ukuze ufinyelele ku-20um noma ngaphansi.Okuhle kakhului-graphite ecindezelwe ngokwe-isostatically, enobukhulu bezinhlayiyana ububanzi obungu-1μm, inhle kakhulu.
3. Ukucindezela okubandayo kwe-isostatic: Faka impushana yomhlabathi emshinini wokucindezela we-isostatic obandayo bese uwucindezela ukuze wenze ngaphansi kwengcindezi ephezulu.
4. Ukugazinga: I-graphite ebunjiwe ifakwa esithandweni sokubhaka futhi yoswe ekushiseni okuphezulu ukuze kuthuthukiswe izinga le-graphitization.
5. Umjikelezo wokugazinga: Ukuze kuzuzwe ukuminyana okuhlosiwe, imijikelezo eminingi yokuthosa iyadingeka.Umjikelezo ngamunye ukhulisa ukuminyana kwe-graphite, ukufeza amandla aphezulu kanye nokuhamba kagesi.
Ukusetshenziswa okuyinhloko kweisostatic graphitezihlanganisa okulandelayo:
1. Inkambu ye-elekthronikhi:I-graphite ecindezelwe ngokwe-Isostaticisetshenziswa kabanzi emkhakheni we-electronics ngenxa ye-conductivity yayo kagesi enhle kakhulu.Ikakhulukazi emikhakheni yamabhethri, ama-electrode, amadivaysi e-semiconductor, njll., ukuqhutshwa kwayo okuhle kukagesi kwenza i-isostatic icindezelwe igraphite ibe yinto ebaluleke kakhulu.
2. Inkambu ye-Aerospace: i-graphite ecindezelwe ye-isostatic inezici zokumelana nokushisa okuphezulu, ukuzinza kwamakhemikhali namandla aphezulu, ngakho-ke isetshenziswa kabanzi emkhakheni we-aerospace.Isibonelo, ezinjinini zamarokhethi nama-space probes,i-graphite ecindezelwe ngokwe-isostaticallyisetshenziselwa ukwenza izingxenye eziqhutshwa ngogesi ngaphansi kwezinga lokushisa eliphezulu, izimo zokucindezela okukhulu.
3. Inkambu yezimoto:i-graphite ecindezelwe isostaticibuye isetshenziswe kabanzi emkhakheni wezimoto.Isibonelo, emkhakheni wamabhethri, i-graphite ecindezelwe isostatically isetshenziselwa ukwenza ama-electrode ebhethri asebenza kahle.Ngaphezu kwalokho, ezingxenyeni zenjini yezimoto, i-graphite ecindezelwe ye-isostatic iphinde isetshenziselwe ukwenza izimpawu nokugqoka izingxenye ngaphansi kokushisa okuphezulu nezimo zengcindezi ephezulu.
4. Eminye imikhakha: Ngaphezu kwezinkambu ezingenhla, i-graphite ye-isostatic nayo isetshenziswa kabanzi kumandla, imboni yamakhemikhali, i-metallurgy neminye imikhakha.Isibonelo, emkhakheni wamaseli elanga,i-graphite ecindezelwe ngokwe-isostaticallyisetshenziselwa ukwenza ama-electrode asebenza kahle kakhulu nama-conductive substrates.Embonini yamakhemikhali,i-graphite ecindezelwe ngokwe-isostaticallyisetshenziselwa ukwenza amapayipi neziqukathi ezinokumelana nokugqwala okuphezulu.Nge-metallurgy,i-graphite ecindezelwe ngokwe-isostaticallyisetshenziselwa ukwenza izitofu zokushisa okuphezulu nama-electrode.
Njengohlobo olusha lwezinto ze-graphite, i-graphite ecindezelwe ye-isostatic inezinhlobonhlobo zokusetshenziswa kanye nenani elibalulekile.Inqubo yokukhiqiza yayo iyinkimbinkimbi futhi ithambile, futhi idinga ukudlula ezinyathelweni eziningi ukuze iqedele.Kodwa-ke, yilezi zinyathelo zenqubo eyinkimbinkimbi eyenza i-graphite ecindezelwe nge-isostatically ibe nezakhiwo ezinhle kakhulu kanye namathemba okusebenza abanzi.Ngokuzayo, ngenqubekelaphambili eqhubekayo yesayensi nobuchwepheshe kanye nokwanda kwezinkambu zokufaka izicelo, i-isostatic ecindezelwe igraphite izosetshenziswa kabanzi futhi ithuthukiswe.Ngaso leso sikhathi, ucwaningo kanye nokwenza ngcono inqubo yokukhiqiza kanye nobuchwepheshe nakho kuzoba yingqikithi yocwaningo.Kukholelwa ukuthi esikhathini esizayo esiseduze, i-graphite ye-isostatic izosilethela ezinye izimanga namathuba.
