Ụzọ maka igbochi flake graphite ịbụ oxidized na oke okpomọkụ

Iji gbochie mmebi mmebi nke oxidation nke flake graphite na okpomọkụ dị elu, ọ dị mkpa ịchọta ihe iji tinye mkpuchi na ihe mkpuchi dị elu, nke nwere ike ichebe graphite flake nke ọma site na oxidation na okpomọkụ dị elu. Iji chọta ụdị flake graphite mgbochi ọxịdashọn uwe, anyị ga-ebu ụzọ guzogide elu okpomọkụ na compactness.
Ọ dị mma, ezigbo nguzogide corrosion, nguzogide oxidation siri ike, ike siri ike na njirimara ndị ọzọ. Furuite Graphite Xiaobian na-ewebata ụzọ iji gbochie graphite flake ka ọ bụrụ oxidized na oke okpomọkụ:

1. Jiri ihe nwere ike ikuku na-erughị 0.1333MPa (1650 * C) na arụmọrụ zuru oke.
2. Họrọ ihe nkedo iko nke na-emezu ihe ndị a chọrọ ka ọ bụrụ ihe na-ekpuchi onwe ya, ma mee ka ọ bụrụ ihe mkpuchi mgbape na okpomọkụ na-arụ ọrụ.
3. Dị ka ọrụ nke ọkọlọtọ free ume nke mmeghachi omume na oxygen na okpomọkụ, na steelmaking okpomọkụ (1650-1750 * C), a na-ahọrọ ihe ndị nwere njikọ dị ukwuu na ikuku oxygen karịa carbon-oxygen na-ahọrọ iji weghara oxygen, ya mere. dị ka oxidize onwe ha na-echebe flake graphite. Mgbe oxidation gasịrị, a na-emepụta usoro ọhụrụ nwere oke olu nke akụkụ mbụ.
Nnukwu, nke na-enye aka igbochi ọwa ikuku oxygen dị n'ime ma mepụta ihe mgbochi oxidation.
4. N'ebe okpomọkụ na-arụ ọrụ, ọnụ ọgụgụ dị ukwuu nke inclusions dị ka Al2O3, SiO2 na Fe2O3 na nchara a wụrụ awụ nwere ike adsorbed, nke na-emeghachi onwe ha na sinter, nke mere na ntinye dị iche iche sitere na nchara gbazere jiri nwayọọ nwayọọ banye mkpuchi.
Okpomọkụ oxidation nke graphite flake emepụtara na China bụ 560815 Celsius C mgbe ọdịnaya carbon bụ 88% 96% na nha nha ahụ karịrị meshes 400. N'ime ha, mgbe urughuru size nke graphite bụ 0.0970.105mm, oxidation okpomọkụ nke graphite na ihe karịrị 90% carbon ọdịnaya bụ 600815 Celsius C na carbon ọdịnaya bụ ihe na-erughị 90%.
The oxidation okpomọkụ nke ink bụ 620790 C. Ka mma na crystalline flake graphite bụ elu oxidation elu okpomọkụ bụ, na obere oxidation arọ ọnwụ bụ na elu okpomọkụ.
