Ojiji nke Graphite

1. Dị ka ihe refractory: Graphite na ngwaahịa ya nwere njirimara nke nguzogide okpomọkụ dị elu na ike dị elu. A na-ejikarị ha eme ihe na ụlọ ọrụ igwe na-emepụta ihe ndị dị na graphite. N'ime nchara, a na-ejikarị graphite eme ihe dị ka ihe nchebe maka ingots ígwè na n'ime liner nke ọkụ ọla.

2. Ihe na-emepụta ihe: ejiri ya na ụlọ ọrụ eletriki dị ka electrode dị mma maka ịmepụta electrodes, brushes, carbon ros, carbon tubes, mercury positive flow devices, graphite gaskets, ekwentị akụkụ, mkpuchi maka telivishọn foto tubes, wdg.

3. Ihe mmanu na-eguzogide iyi: A na-ejikarị graphite eme ihe dị ka mmanu na ụlọ ọrụ igwe. A naghị eji mmanụ lubricating eme ihe n'okpuru ọsọ ọsọ, okpomọkụ dị elu na ọnọdụ nrụgide dị elu, ebe graphite na-eyi ihe na-eguzogide ọgwụ nwere ike ịrụ ọrụ na ọsọ ọsọ ọsọ nke 200 ~ 2000 Celsius C na-enweghị mmanụ mmanụ. A na-eji ọtụtụ ngwa ndị na-ebu mgbasa ozi na-emebi emebi na ihe graphite iji mee iko piston, akara na bearings. Ọ dịghị mkpa ka a tee ha mmanụ mgbe a na-arụ ọrụ.

4. Graphite nwere ezigbo nkwụsi ike nke kemịkal. graphite edoziri nke ọma, nke nwere njirimara nke nguzogide corrosion, ezigbo conductivity thermal na permeability dị ala, a na-eji ya eme ihe n'ichepụta ndị na-ekpo ọkụ, tankị mmeghachi omume, condensers, ụlọ ọkụ ọkụ, ụlọ elu absorption, coolers, heaters, nzacha. , akụrụngwa mgbapụta. A na-ejikarị eme ihe na petrochemical, hydrometallurgy, acid na alkali mmepụta, eriri sịntetik, akwụkwọ na ụlọ ọrụ mmepụta ihe ndị ọzọ, nwere ike ịzọpụta ọtụtụ ihe ígwè.

5. Maka nkedo, sanding, mkpakọ ịkpụzi na pyrometallurgical ihe: N'ihi na graphite nwere obere okpomọkụ mgbasa ọnụọgụ na ike iguzogide ngwa ngwa jụrụ na ngwa ngwa mgbanwe, ọ nwere ike iji dị ka ihe ebu maka glassware. Mgbe ijiri graphite, metal ferrous nwere ike iji nweta nha nkedo ziri ezi yana ngwucha elu elu. Enwere ike iji ya na-enweghị nhazi ma ọ bụ obere nhazi, si otú a na-azọpụta ọtụtụ ígwè.

6, maka ụlọ ọrụ ike atọm na ụlọ ọrụ nchekwa mba: graphite nwere ezigbo neutron moderator maka ojiji na reactor atomic, uranium-graphite reactor bụ ihe eji eme ihe n'ọtụtụ ebe. The decelerating ihe na nuklia reactor dị ka ike isi iyi kwesịrị inwe a elu agbaze ebe, kwụsiri ike, na corrosion-eguzogide Njirimara, na graphite nwere ike zuru ezu mezu ihe ndị a chọrọ n'elu. Ịdị ọcha nke graphite e ji mee ihe dị ka ihe na-emepụta ihe na-emepụta ihe dị elu nke ukwuu, na ọdịnaya adịghị ọcha ekwesịghị ịfe iri puku kwuru iri PPM. Karịsịa, ọdịnaya boron kwesịrị ịbụ ihe na-erughị 0.5 PPM. N'ime ụlọ ọrụ nchekwa, a na-ejikwa graphite na-emepụta ihe mkpuchi rọketị mmanụ siri ike, cones imi ogbunigwe, akụkụ nke akụrụngwa igodo oghere, ihe mkpuchi na ihe nchebe radieshon.

7. Graphite na-egbochikwa imebi mmiri ọkụ. Ịtinye ụfọdụ ntụ ntụ graphite na mmiri (ihe dị ka gram 4 ruo 5 kwa tọn mmiri) na-egbochi imetọ n'elu ebe a na-esi mmiri ọkụ. Tụkwasị na nke ahụ, a pụrụ iji graphite kpuchie ya na chimni ígwè, ụlọ elu, àkwà mmiri na ọkpọkọ iji gbochie mmebi na nchara.
8. Enwere ike iji eserese eserese dị ka ụzọ pensụl, pigmenti, na onye na-ekpocha ihe. Mgbe nhazi pụrụ iche nke graphite gasịrị, enwere ike ịmepụta ihe dị iche iche pụrụ iche maka ụlọ ọrụ mmepụta ihe dị mkpa.
9. Electrode: Graphite nwere ike dochie ọla kọpa dị ka electrode. N'afọ ndị 1960, a na-eji ọla kọpa mee ihe n'ọtụtụ ebe dị ka ihe electrode, yana ọnụ ọgụgụ ojiji nke ihe dịka 90% na graphite nke nanị ihe dịka 10%. Na narị afọ nke 21, ọtụtụ ndị ọrụ malitere ịhọrọ graphite dị ka ihe electrode, na Europe, karịa 90%. Ihe electrode dị n'elu bụ graphite. Ọla kọpa, ihe bụbu ihe elektrọd na-achịbu, ọ fọrọ nke nta ka ọ bụrụ na ọ tụfuru uru ya ma e jiri ya tụnyere electrodes graphite. Graphite ji nwayọọ nwayọọ dochie ọla kọpa dị ka ihe a na-ahọrọ maka electrodes EDM.
