Graphite ebu maka na-aga n'ihu mgbatị
Na-aga n'ihu mgbatị graphite ebu na-ezo aka graphite ngwaahịa eji na-aga n'ihu mgbatị Ebu. Metal-aga n'ihu mgbatị technology bụ a ọhụrụ technology na ozugbo amama wụrụ awụ metal n'ime a ihe site a na-aga n'ihu mgbatị ebu. N'ihi na ọ naghị agagharị ma na-aghọ ihe ozugbo, a na-ezere ikpo ọkụ nke abụọ nke metal, yabụ enwere ike ịchekwa ọtụtụ ike.
A na-aga n'ihu na-eme ka eserese eserese sitere na carbonaceous ngwaọrụ (mmanụ coke, coke pitch, kol ...) mgbe usoro usoro mmepụta. N'etiti ha, mkpakọ ịkpụzi usoro nwere ike karị oyi mpikota mkpakọ ịkpụzi ma ọ bụ oyi isostatic ịpị ịkpụzi usoro. The elu elu-tonnage oyi isostatic ịpị usoro na nakweere iji hụ na mmepụta nke edo, ok na elu-ike na-aga n'ihu mgbatị graphite. Asingba elu mkpuchi teknụzụ ọgwụgwọ nwere ike ịbụ abụ ndụ ọrụ nke graphite crystallizer, meziwanye ogo nke mgbatị mgbatị na-aga n'ihu, ma mee ka usoro mgbatị na-aga n'ihu.
E jiri ya tụnyere ihe eji eme ihe maka ebumnuche ndị ọzọ, ihe nkedo graphite na-aga n'ihu nwere njirimara ndị a: ezigbo ahụrụ, ụdị edo edo, ogo dị elu, obere porosity na ike dị elu. Ihe omuma ya bu ihe ndia:

Isi nke mmepe nke na-aga n'ihu mgbatị graphite n'ụlọ na mba ọzọ
1) Mba itinye nnukwu mkpa maka mmepe na ntinye nke graatị graphite na-aga n'ihu. Enwere ike ikwenye nke a site na mmụba na ọtụtụ mgbatị na-aga n'ihu na-aga n'ihu, mmezi usoro, na mma mma. Ka ihe atụ, Germany na Japan amaja imefu a otutu ego na usoro nke na-emepe emepe na-aga n'ihu mgbatị graphite, n'ihi ya, ha na-emepụta ihe iche iche nke na-aga n'ihu mgbatị graphite, na àgwà dịkwa mma. Ọla kọpa profaịlụ na igba ígwè na-aga n'ihu mgbatị technology na-dịtụ mepụtara.
2) Na ntuziaka nke mmepe ngwaahịa, mba ndị mba ọzọ etinyekwuola uche na mmepe nke ezi grained, elu-njupụta, isotropic graphite dị ka na-aga n'ihu mgbatị graphite. Karịsịa, ụlọ ọrụ German Linsdorf enwetawo ahụmịhe dị ukwuu na mpaghara a ma were ọtụtụ usoro. 'Slọ ọrụ Toyo Tansuo nke Japan na-achọkwa, ọ nwere ikike ịkarị. Na China, Dongshin Electric Carbon Plant na Shanghai Carbon Plant enweela ihe ịga nke ọma na mpaghara a afọ ole na ole gara aga. Iji meziwanye arụmọrụ nke ọrụ na-arụ ọrụ nke graphite crystallizer, a na-anakwere teknụzụ mkpuchi elu, nke nwere mmetụta dị ukwuu na mmelite nke ndụ ọrụ nke nkedo graphite na-aga n'ihu. Soviet Union nakweere teknụzụ mkpuchi boron nitride, ebe mkpuchi nke graphite castite na mba m na-edebekarị pyrolytic graphite. Ọ bụ ezie na anaghị ewu ewu ebe niile, ọtụtụ ndị ọrụ nabatara ya. Tụkwasị na nke ahụ, Shanghai Electric Carbon Plant na-ejikwa usoro ọdịnala iji gbakwunye 0.6 na 2% nke ígwè oxides, ma na-eji usoro nke ihe ndị a dị iche iche iji gbanwee n'ime ebe ndị na-agbaze agbaze na 2500 ℃ dị elu na-ekpo ọkụ, si otú ahụ na-emeziwanye nkwụsị nke oxidation nke na-aga n'ihu mgbatị graphite. Iji mezuo nzube nke imeziwanye ọrụ ndụ.
3) The nnukwu-ọnụ ọgụgụ nkọwapụta nke na-aga n'ihu mgbatị graphite aghọwo a kacha mkpa. N'ihi eziokwu ahụ bụ na ogo nke nnukwu ihe osise na-aga n'ihu na-enwe nnukwu ọdịiche ma e jiri ya tụnyere mba ndị ọzọ, a ga-agbasi mbọ ike ịzụlite ya. Nke a kwesiri ndị nlebara anya dị mkpa, ma maka uru mmekọrịta mmadụ na ibe ya.
4) Na mba m, teknụzụ mgbatị na-aga n'ihu nke profaịlụ ọla kọpa amalitela ngwa ngwa, bidoro na mbụ, nwee ọkwa buru ibu, ma nwee ahụmịhe tozuru oke na ọgaranya. The na-aga n'ihu mgbatị technology nke na-aga n'ihu mgbatị profaịlụ ọhụrụ mepụtara, na-aga n'ihu mgbatị technology chọrọ Ọ bụ ezie na nkedo graphite nwere ike ka na-eji, n'ihu mma na mma dị mkpa.
5) Research ga-rụrụ iji melite machining ziri ezi nke na-aga n'ihu mgbatị graphite ebu ma melite ngwaahịa Ọdịdị. Nke a bụkwa otu n'ime usoro iji melite ndụ nke graphite crystallizer. Germany na Soviet Union nwere ihe doro anya chọrọ maka ịkpụzi ngwaahịa na ịkpụzi ngwaahịa, ndị ọrụ ụlọ nwekwara olile anya na ike ike nke mgbidi dị n'ime ime ihe nkedo na-aga n'ihu nwere ike ịbawanye mma, nke nwere ike igbochi mgbawa n'elu nkedo. Na mgbakwunye, iji melite steeti ịkpọtụrụ. The udi na Ọdịdị nke na-aga n'ihu mgbatị graphite kwesịrị mma nke mere na kọntaktị ebe n'etiti ya na ọla kọpa ebu esịmde 80%.
