Isostatic pressed graphite bụ ụdị ihe ọhụrụ graphite, nke nwere ezigbo ọkụ eletrik, nkwụsi ike dị elu na nkwụsi ike kemịkal, ya mere a na-eji ya n'ọtụtụ ebe teknụzụ dị elu.Akwụkwọ a ga-ewebata n'ụzọ zuru ezu usoro mmepụta, isi ojiji na n'ọdịnihu mmepe omume nke isostatic pressed graphite.
Mmepụta usoro nke isostatic 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.graphite kacha mma nke etinyere nke ọma, yana dayameta irighiri ihe dị 1μm, dị ezigbo 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. Impregnation-roasting okirikiri: Iji nweta njupụta nke ebumnuche, a na-achọrọ ọtụtụ okirikiri impregnation-roasting.Ọkpụkpụ ọ bụla na-abawanye njupụta nke graphite, na-enweta ike dị elu na eletriki eletrik.
Isi ojiji nke graphite isostatic gụnyere ihe ndị a:
1. Ebe eletrọnịkị: A na-eji graphite dị iche iche eme ihe n'ọhịa nke eletrọnịkị n'ihi nrụpụta eletrik dị mma.Karịsịa n'ọhịa nke batrị, electrodes, semiconductor ngwaọrụ, wdg, ya magburu onwe eletriki conductivity na-eme ka isostatic pịa graphite ihe dị oké mkpa.
2. Aerospace ubi: isostatic pressed graphite nwere àgwà nke elu okpomọkụ nguzogide, kemịkalụ kwụsie ike na elu ike, n'ihi ya, ọ na-ọtụtụ ebe na aerospace ubi.Dịka ọmụmaatụ, n'ime igwe rọketi na nyocha oghere, a na-eji graphite nke isostatically eme ihe na-eme ihe na-eduzi eletrik n'okpuru oke okpomọkụ, ọnọdụ nrụgide dị elu.
3. Ogige ụgbọ ala: A na-ejikwa graphite nke isostatic eme ihe 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 ma na-eyi akụkụ n'okpuru oke okpomọkụ 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, n'ọhịa nke mkpụrụ ndụ anyanwụ, a na-eji graphite nke a na-agbanye n'ụzọ dị iche iche na-emepụta electrodes na ihe ndị na-eduzi nke ọma.N'ime ụlọ ọrụ kemịkalụ, a na-eji graphite nke isostatically eme ihe iji mee ọkpọkọ na arịa nwere nnukwu nguzogide corrosion.Na metallurgy, a na-eji graphite nke a na-etinye n'ụdị isostatically mee ka stovu na electrodes dị elu.
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 ka ọ gafee ọtụtụ usoro iji wuchaa.Otú ọ dị, ọ bụ usoro usoro ndị a dị mgbagwoju anya na-eme ka graphite nke isostatically nwee mmetụta 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.
