Ibyiza bya magnesia amatafari ya karubone ni:Kurwanya isuri hamwe no guhangana nubushyuhe bwiza.Mu bihe byashize, ibibi by'amatafari ya MgO-Cr2O3 n'amatafari ya dolomite ni uko byinjije ibice bya slag, bikaviramo gusenyuka kw'imiterere, bigatuma byangirika hakiri kare.Mugushyiramo grafite, amatafari ya karubone ya magnesia yakuyeho iyi nenge.Ikiranga ni uko icyapa cyinjira gusa mubikorwa bikora, bityo reaction ya reaction Igarukira kumurimo ukora, imiterere ifite ibishishwa bike kandi ubuzima burebure.

Noneho, usibye asfalt gakondo hamwe na resin-ihujwe na magnesia amatafari ya karubone (harimo n'amatafari ya magnesia yatewe amavuta),amatafari ya karubone ya magnesia yagurishijwe ku isoko arimo:

(1) Amatafari ya karubone ya Magnesia akozwe muri magnesia arimo 96% ~ 97% MgO na grafite 94% ~ 95% C;

(2) Amatafari ya karubone ya Magnesia akozwe muri magnesia arimo 97.5% ~ 98.5% MgO na grafite 96% ~ 97% C;

(3) Amatafari ya karubone ya Magnesia akozwe muri magnesia arimo 98.5% ~ 99% MgO na 98% ~ C.

Ukurikije ibirimo karubone, amatafari ya karubone ya magnesia agabanijwemo:

(I) Amatafari ya magnesia yatewe amatafari (ibirimo karubone bitarenze 2%);

(2) Amatafari ya magnesia ahujwe (karubone iri munsi ya 7%);

.Antioxydants ikunze kongerwaho asfalt / resin ihujwe na magnesia amatafari ya karubone (ibirimo karubone ni 8% kugeza 20%).

Amatafari ya karubone ya Magnesia akorwa muguhuza umucanga wa MgO ufite isuku nyinshi na grafite scaly, karubone yumukara, nibindi. Igikorwa cyo gukora gikubiyemo inzira zikurikira: kumenagura ibikoresho fatizo, kumenagura, gushyira amanota, kuvanga ukurikije igishushanyo mbonera cyibikorwa no gushyiraho ibicuruzwa, ukurikije ihuriro Ubushyuhe bwubwoko bwa agent buzamurwa bugera kuri 100 ~ 200 and, hanyuma bugahuzwa hamwe na binder kugirango babone icyitwa MgO-C icyondo (imvange yumubiri wicyatsi).Ibikoresho by'ibyondo bya MgO-C ukoresheje resinike ya sintetike (cyane cyane resin fenolike) ibumbabumbwa mubukonje;ibikoresho by'ibyondo bya MgO-C bifatanije na asfalt (ashyutswe kumiterere y'amazi) ibumbabumbwa muburyo bushyushye (hafi 100 ° C).Ukurikije ingano yicyiciro hamwe nibikorwa bisabwa mubicuruzwa bya MgO-C, ibikoresho byo kunyeganyega bya vacuum, ibikoresho byo kubumba compression, extruders, imashini isostatike, imashini zishyushye, ibikoresho byo gushyushya, hamwe nibikoresho bya ramming birashobora gukoreshwa mugutunganya ibikoresho byondo bya MgO-C.Kuri Imiterere.Umubiri MgO-C wakozwe ushyirwa mu itanura kuri 700 ~ 1200 ° C kugirango bivure ubushyuhe kugirango uhindure ibintu bihuza karubone (iyi nzira yitwa karubone).Kugirango wongere ubwinshi bwamatafari ya karubone ya magnesia no gushimangira ubumwe, ibyuzuza bisa na binders nabyo birashobora gukoreshwa mugutera inda amatafari.

Muri iki gihe, resinike ya sintetike (cyane cyane fenolike resin) ikoreshwa cyane nkibikoresho bihuza amatafari ya karubone ya magnesia.Gukoresha sintetike resin ihujwe na magnesia amatafari ya karubone afite ibyiza byibanze bikurikira:

(1) Ibidukikije byemerera gutunganya no kubyaza umusaruro ibyo bicuruzwa;

(2) Inzira yo gukora ibicuruzwa mubihe bivanze bikonje bizigama ingufu;

(3) Igicuruzwa gishobora gutunganywa mugihe kidakira;

(4) Ugereranije na bisi ya asfalt, nta cyiciro cya plastiki;
