I-Isosatic Graphite
Izici zobuchwepheshe bokucindezela i-isostatic
(1) Ubuningi bemikhiqizo yokucindezela i-isostatic buphezulu, okuvamise ukuthi kube ngu-5% -15% ngaphezulu kunalolo lwe-unidirectional kanye nezindlela ezimbili zokubumba. Ubuningi obuhlobene bemikhiqizo eshisayo ye-isostatic ingafinyelela ku-99.80% -99.99%.
(2) Ubuningi be-compact bufana. Ekucindezelweni kokubumba, noma ngabe kuyindlela eyodwa noma izindlela ezimbili zokucindezela, ukusatshalaliswa kokuxinana okuluhlaza okuluhlaza kuzobe kungalingani. Lokhu kuguqulwa kobuningi kuvame ukufinyelela ngaphezu kwe-10% lapho ucindezela imikhiqizo enezimo eziyinkimbinkimbi. Lokhu kudalwa ukumelana okungqubuzanayo phakathi kwempuphu nesikhunta sensimbi. Ingcindezi yokudlulisa imidiya ye-Isostatic fluid, ilingana kuzo zonke izinkomba. Ukuminyaniswa kwemvilophu nempuphu kucishe kufane. Akukho ukunyakaza okuhlobene phakathi kwempuphu nemvilophu. Kukhona ukumelana okuncane kokungqubuzana phakathi kwabo, futhi ingcindezi yehla kancane kuphela. I-gradient yokwehla kobuningi imvamisa ingaphansi kuka-1%. Ngakho-ke, kungacatshangwa ukuthi okungenalutho Ubuningi besibalo bufana.
(3) Ngenxa yobuningi obufanayo, isilinganiso sesici sokukhiqiza singalinganiselwa, esivumayo ekukhiqizweni kwemikhiqizo emise okwenduku, eyizigaxa, emincane futhi emide.
(4) Inqubo yokubumba isostatic ngokuvamile ayidingi ukwengeza i-lubricant kwimpuphu, enganciphisi kuphela ukungcoliswa komkhiqizo, kepha futhi yenza lula inqubo yokukhiqiza.
(5) Imikhiqizo ecindezelwe ngokwe-Isostatic inokusebenza okuhle kakhulu, umjikelezo wokukhiqiza omfushane nobubanzi besicelo obubanzi.
(6) Ububi benqubo yokucindezela i-isostatic ukuthi ukusebenza kahle kwenqubo kuphansi futhi okokusebenza kuyabiza.
Izici ze-isostatic graphite materials
(1) Isotropic
Ngokuvamile, izinto ezinesilinganiso se-isotropy se-1.0 kuye ku-1.1 zibizwa ngokuthi izinto ze-isotropic. Ngenxa yokucindezela kwe-isostatic, i-isotropy ye-isostatic graphite ingaba ngaphakathi kwe-1.0 kuye ku-1.1. I-isotropy ye-isostatic graphite ithinteka ngenqubo yokwelashwa kokushisa, i-isotropy yezinhlayiya ze-powder nenqubo yokubumba.
Enqubweni yokwelashwa kokushisa kwe-isostatic graphite, ukushisa kudluliswa kancane kancane kusuka ngaphandle kuye ngaphakathi, futhi izinga lokushisa lincipha kancane kancane lisuka ngaphandle liye ngaphakathi. Ukufana kokushisa kwangaphandle kungcono kunokufana kokushisa kwangaphakathi. I-Homotropy ingcono kuneyangaphakathi.
Ngemuva kokufakwa kwe-binder pitch, isakhiwo se-microcrystalline esakhiwe asinamphumela omncane ku-isotropy yebhulokhi ye-graphite. Uma i-isotropy yezinhlayiya ze-powder yinhle, noma ngabe kusetshenziswa ukubumba kokucindezelwa, i-isotropy ingalungiswa. I-graphite ene-homogeneity enhle.
Ngokuya ngenqubo yokubumba, uma i-binder pitch ne-powder kungaxutshiwe ngendlela efanayo, kuzophinda kuthinte i-isotropy ye-isostatic graphite.
(2) Usayizi omkhulu nesakhiwo esihle
Akunakwenzeka ukulungisa imikhiqizo yekhabhoni enezincazelo ezinkulu nezakhiwo ezinhle ngokucindezela kokubumba. Ngezinga elithile, ukucindezelwa kwe-isostatic kunganqoba ukushiyeka kokungalingani komthamo womkhiqizo okungalingani okubangelwe ukucindezela ukubumba, kunciphise kakhulu amathuba wokuqhekeka komkhiqizo, futhi kwenze ukukhiqizwa kwemikhiqizo yosayizi omkhulu nokuhle kube ngokoqobo.
(3) Ukufana
Isakhiwo sangaphakathi se-isostatic graphite silingana ngokufana, futhi ukuminyana kwenqwaba, ukuvimbela amandla namandla engxenye ngayinye akuhlukile kakhulu. Ingathathwa njengezinto ezi-homogeneous ze-graphite. I-homogeneity ye-isostatic graphite inqunywa yindlela yokucindezela yokucindezela kwe-isostatic. Lapho kusetshenziswa ukucindezelwa kwe-isostatic, umphumela wokudluliswa kwengcindezi eceleni kokucindezela kuyafana, ngakho-ke ukuminyana kwevolumu yengxenye ngayinye ye-isostatic ngokucindezela i-graphite kuyefana.
