Isostatic pịa graphitebụ ụdị ihe ọhụrụ graphite, nke nwere ezigbo ọkụ eletrik, nkwụsi ike dị elu na nkwụsi ike nke kemịkal, ya mere a na-eji ya n'ọtụtụ ebe dị elu. Akwụkwọ a ga-ewebata n'ụzọ zuru ezu usoro mmepụta, isi ojiji na n'ọdịnihu mmepe omume nkeisostatic pịa graphite.
Usoro mmepụta nkeisostatic pịa graphite
Usoro mmepụta nke graphite isostatic gụnyere usoro ndị a:
1. Nkwadebe ihe eji eme ihe: Ihe eji eme ihe nke graphite nke isostatic gbakwunyere na-agụnye nchịkọta na ihe nkedo. A na-ejikarị petroleum coke ma ọ bụ coke asphalt eme ihe, nke a ga-agbakọ na 1200 ~ 1400 ℃ iji wepụ mmiri mmiri na ihe na-agbanwe agbanwe tupu enwee ike iji ya. Ihe nkedo bụ nke coal pitch ma ọ bụ petroleum pitch, nke na-agbasawanye na nkwekọrịta synchronously na mkpokọta iji hụ na isotropy nke ihe onwunwe.
2. Na-egweri: A na-agbanye ihe ọkụkụ n'ime ntụ ntụ dị mma, nke na-achọkarị mkpokọta nha iji ruo 20um ma ọ bụ obere. Nke kacha mmagraphite etinyere nke ọma, na oke urughuru dayameta nke 1μm, dị nnọọ mma.
3. Cold isostatic pressing: Tinye ntụ ntụ n'ime igwe na-ekpo ọkụ nke isostatic oyi ma pịa ya ka ọ na-etolite n'okpuru nrụgide dị elu.
4. Nri: A na-etinye graphite a na-akpụ akpụ n'ime ọkụ na-esi nri ma kpochaa ya na okpomọkụ dị elu iji meziwanye ogo nke graphitization.
5. Mgbochi-eri nri nke impregnation: Iji nweta njupụta nke ebumnuche, a na-achọrọ ọtụtụ cycles impregnation-roasting. Ọkpụkpụ ọ bụla na-abawanye njupụta nke graphite, na-enweta ike dị elu na eletriki eletrik.
Isi ojiji nkegraphite isostaticgụnyere ihe ndị a:
1. Ebe eletrọnịkị:graphite etinyere n'ụzọ dị ichea na-ejikarị ya eme ihe n'ọhịa nke eletrọnịkị n'ihi ọmarịcha ọkụ eletrik ya. Karịsịa n'ọhịa nke batrị, electrodes, semiconductor ngwaọrụ, wdg, ya mma eletriki conductivity na-eme ka isostatic pịa graphite ihe dị oké mkpa.
2. Aerospace ubi: isostatic pressed graphite nwere njirimara nke nguzogide okpomọkụ dị elu, nkwụsi ike nke kemịkal na ike dị elu, n'ihi ya, a na-ejikarị ya eme ihe na mbara igwe. Dịka ọmụmaatụ, n'ime igwe rọketi na nyocha oghere,graphite etinyere nke ọmaa na-eji ya eme ihe ndị na-eduzi ọkụ eletrik n'okpuru okpomọkụ dị elu, ọnọdụ nrụgide dị elu.
3. Ogige ụgbọ ala:isostatic pịa graphitea na-ejikwa ebe niile na mpaghara ụgbọ ala. Dịka ọmụmaatụ, n'ọhịa batrị, a na-eji graphite nke a na-agbanye n'ụzọ dị iche iche na-eme ka electrodes batrị dị elu. Na mgbakwunye, na akụrụngwa injin ụgbọ ala, a na-ejikwa graphite isostatic pressed iji rụpụta akara na iyi akụkụ n'okpuru ọnọdụ okpomọkụ dị elu na ọnọdụ nrụgide dị elu.
4. Ugbo ndị ọzọ: Na mgbakwunye na mpaghara ndị dị n'elu, a na-ejikwa graphite isostatic na ike, ụlọ ọrụ kemịkalụ, metallurgy na ubi ndị ọzọ. Dịka ọmụmaatụ, na ngalaba nke mkpụrụ ndụ anyanwụ.graphite etinyere nke ọmaa na-eji na-eme nke ukwuu ịrụ ọrụ nke ọma electrodes na conductive substrates. N'ime ụlọ ọrụ kemikal,graphite etinyere nke ọmana-eji na-eme ka ọkpọkọ na containers na elu corrosion eguzogide. Na metallurgy,graphite etinyere nke ọmaa na-eji eme stovu okpomọkụ na electrodes.
Dị ka ụdị ihe ọhụrụ graphite, graphite isostatic pressed nwere ọtụtụ ojiji na uru dị mkpa. Usoro mmepụta ya dị mgbagwoju anya ma dị nro, ọ dịkwa mkpa ịgafe ọtụtụ usoro iji wuchaa. Otú ọ dị, ọ bụ usoro usoro mgbagwoju anya ndị a na-eme ka graphite nke a na-agbanye n'ahụ nwere ihe magburu onwe ya na atụmanya ngwa ngwa. N'ọdịnihu, na ọganihu sayensị na nkà na ụzụ na-aga n'ihu na mgbasawanye nke mpaghara ngwa, a ga-eji graphite nke isostatic eme ihe ma kwalite ya. N'otu oge ahụ, nyocha na mmelite nke usoro mmepụta na nkà na ụzụ ga-abụkwa ihe nyocha nke nyocha. A kwenyere na n'ọdịnihu dị nso, graphite isostatic ga-ewetara anyị ihe ịtụnanya na ohere.
