Kedu ihe bụ carbon ojii?

Carbon ojii, bụ carbon amorphous, ọkụ, rụrụ arụ na ezigbo ntụ ntụ ojii, nke enwere ike ịghọta dị ka ala nke ite ahụ.

Ọ bụ ngwaahịa a na-enweta site na ọkụ na-ezughị ezu ma ọ bụ mkpọ ọkụ nke ihe carbonaceous dị ka coal, gas, mmanụ dị arọ, na mmanụ mmanụ n'okpuru ọnọdụ ikuku na-ezughị ezu.


Carbon Black


Akụkụ bụ isi nke oji ojii bụ carbon, nke bụ nanomaterial mbụ mepụtara, etinyere ma na-emepụta ugbu a site n'aka ụmụ mmadụ. , edepụtara dị ka otu n'ime ngwaahịa kemịkalụ iri abụọ na ise na ezigbo ngwaahịa kemịkalụ nke ụlọ ọrụ kemịkalụ mba ụwa.

Ụlọ ọrụ ojii nke carbon dị oke mkpa maka ụlọ ọrụ taya taya, ụlọ ọrụ ịcha akwa na imeziwanye ngwaahịa ndụ obodo.



Nke abụọ, nhazi nke carbon ojii

1. Dị ka mmepụta

Ekewara nke ọma na oriọna ojii, gas ojii, oku ọkụ ojii na oghere ojii.


2. Dị ka nzube ya si dị

Dị ka ojiji dị iche iche si dị, a na-ekewakarị oji carbon na carbon ojii maka pigmenti, carbon ojii maka roba, carbon ojii na-eduzi na oji carbon pụrụ iche.


Carbon ojii maka pigmenti - Na mba ụwa, dịka ike agba agba nke carbon ojii si dị, a na-ekewakarị ya n'ụdị atọ, ya bụ carbon ojii dị elu, ọkara-pigment carbon ojii na obere agba carbon ojii.

A na-anọchi anya nkewa a site na mkpụrụedemede Bekee atọ, mkpụrụedemede abụọ mbụ na-egosi ike agba carbon ojii, akwụkwọ ozi ikpeazụ na-egosi usoro mmepụta.


3. Dị ka ọrụ ahụ si dị

Ekewara nke ọma na carbon ojii agbasiri ike, carbon ojii nwere agba, carbon ojii na-eduzi, wdg.


4. Dị ka ihe nlereanya

Ekewara ya na N220,


Ngwa na ụlọ ọrụ roba

Oji ojii ejiri mee ihe na ụlọ ọrụ rọba na-akpata ihe karịrị 90% nke mkpokọta ojii carbon. A na-ejikarị ya eme ụdị taya dị iche iche, dị ka taya ụgbọ ala, taya traktọ, taya ụgbọ elu, taya ụgbọ ala ike, taya igwe igwe, wdg. Ihe dị ka kilogram 10 nke carbon ojii dị mkpa iji rụpụta taya ụgbọ ala nkịtị.


Na carbon ojii maka roba, ihe karịrị ụzọ atọ n'ụzọ anọ nke carbon ojii na-eji na-emepụta taya, ndị ọzọ na-eji ihe ndị ọzọ roba ngwaahịa, dị ka teepu, hoses, akpụkpọ ụkwụ roba, wdg N'ime ụlọ ọrụ ngwaahịa roba. , oriri nke carbon ojii na-akpata ihe dịka 40 ~ 50% nke oriri nke roba.


Ihe kpatara eji eji oji carbon eme ihe nke ukwuu na rọba bụ ihe magburu onwe ya nke a na-akpọ "ike" ike. Achọpụtara ikike "ịkwado" nke carbon ojii na mbụ na rọba eke dị ka n'afọ 1914. Ugbu a ekwenyela na maka roba sịntetik, ike na-eme ka carbon ojii na-arụ ọrụ dị mkpa karị.


Ihe ịrịba ama kachasị mkpa nke nkwado ojii nke carbon bụ iji melite arụmọrụ ike nke taya taya. Taya nwere oji carbon oji 30% gbasiri ike nwere ike ịga kilomita 48,000 ruo 64,000; ka ọ na-ejuputa otu ego inert ma ọ bụ ihe na-adịghị eme ka ọ dị elu kama carbon Black, ọnya ya bụ naanị kilomita 4800.


Na mgbakwunye, carbon ojii agbasiri ike nwekwara ike melite njirimara anụ ahụ na arụ ọrụ nke ngwaahịa rọba, dị ka ike mgbakasị na ike ndọka. Dịka ọmụmaatụ, ịgbakwụnye carbon ojii na-agba ume na rọba kristal dị ka roba eke ma ọ bụ neoprene nwere ike ịbawanye ike tensile site n'ihe dị ka ugboro 1 ruo 1.7 ma e jiri ya tụnyere roba vulcanized na-enweghị oji carbon; Na roba, enwere ike ịbawanye ya ruo ihe dị ka ugboro 4 ruo 12.


N'ime ụlọ ọrụ roba, ụdị oji carbon na ọnụọgụ ya kwesịrị ikpebi dabere na ebumnuche na ọnọdụ ojiji nke ngwaahịa ahụ. Dịka ọmụmaatụ, maka nzọ ụkwụ taya, a ga-ebu ụzọ tụlee nguzogide iyi, ya mere, carbon ojii na-agba ume dị elu, dị ka ọkụ ọkụ na-eguzogide ultra-abrasion oji, ọkụ ọkụ na-eguzogide elu nke ojii ma ọ bụ nnukwu ọkụ ọkụ na-eguzogide oji, chọrọ. ; ebe a na-azọ ụkwụ na rọba anụ ahụ Ihe na-achọ carbon ojii nwere obere ọnwụ hysteresis na obere okpomọkụ ọgbọ.
