Carbon eriri mmetụta
Okwu mmeghe
Carbon na Graphite nwere mmetụta dị nro na-eme ka mmiri na-adịkarị jụụ nke na-ejikarị oghere na gburugburu ikuku na-echebe ruo 5432 ℉ (3000 ℃). Ọdịdị dị elu chere na a na-eme ka okpomoku dị 4712 ℉ (2600 ℃) yana Halogen ọcha dị maka iwu mmepụta omenala. Na mgbakwunye, enwere ike iji ihe ndị ahụ mee ihe na oxidizing okpomọkụ ruo 752 ℉ (400 ℃).
Carbondị carbon carbon emegharị ka a na-enwe mmetụta kachasị, akwa, filaments, yana eriri akwukwo nri (viscose fiber) ma ọ bụ polymer ndị ọzọ dị ka ihe akụrụngwa, na-ebu ụzọ kee ma rụọ ọrụ carbonized. Ihe bụ isi bụ carbon. Atọm carbon dị n'ụdị nke enweghị nrịba nke microcrystals dị iche iche na eriri carbon emegharịrị. Ịtụ ịtụ akụkụ atọ akụkụ adịghị mma.
Omume ozo bu na o nwere nnukwu mbara elu ya, a na-emeghekwa otutu micropores n’elu ukpulu. Na adsorption na desorption, ụzọ adsorption ụzọ dị mkpụmkpụ, na adsorbent nwere ike ịbanye na micropores.Nke a na-enye ọnọdụ maka adsorption ngwa ngwa nke eriri carbon emegharịrị na iji ezigbo micropores rụọ ọrụ.
Mpaghara a kapịrị ọnụ nke carbon nke eriri rụọ ọrụ buru ibu, a na-emepụta pores nke ọma, arụmọrụ adsorption dị elu, ngwa desorption dị ngwa ngwa, enwere ike iji ya ugboro ugboro na ndị ọzọ.
Kedu ihe dị iche na Pan & Rayon Felts?
A na-eji polyacrylonitrile, makwaara dị ka PAN, nwere eriri ọkpọka buru ibu nke na - ebute nsị ala dị ala na mmegide nke mma. Ihe a na-agbanwe agbanwe siri ike ma di nro karie aka aka ma e jiri ya tụnyere Rayon. Ọrụ ọkụ ọkụ nke Rayon dị ala karịa PAN na okpomọkụ karịa 3272 ℉ (1800 ℃).
Maka ngwa ndị metụtara ikpo ọkụ, ụlọ ọrụ anyị na-atụ aro PAN carbon nke ọma n'ihi ihe ndị na-ejikwa ngwa ngwa na ọnụego dị ala. Ọ bụrụ n’ịrụ ọrụ na okpomoku karịrị 3272 ℉ (1800 ℃), biko jiri Rayon.
