Hlalutya ubudlelwane phakathi kwe-white corundum powder kunye ne-alumina

Abavelisi abaninzi beemveliso ezinqabileyo zokunxiba bafuna i-powder emhlophe ye-corundum, kodwa yintoni umsebenzi we-powder emhlophe ye-corundum, iqulunqwe njani, kunye nobudlelwane phakathi komgubo omhlophe we-corundum kunye ne-alumina? Okulandelayo, siya kuqhuba uhlalutyo olunzulu lobudlelwane phakathi kwabo bobabini.

I-White Corundum yintlobo yeentlobo eziqhelekileyo ze-corundum ezixubileyo kwiimveliso ze-abrasive. Ubudlelwane phakathi komgubo omhlophe we-corundum kunye ne-alumina kukuba yenziwa ngokunyibilika kobushushu obuphezulu nge-alumina powder njengeyona nto iphambili. Umxholo we-Al2O3 ngokuqhelekileyo ngu-97% -99%, omhlophe. I-corundum emhlophe inobunzima obuphezulu, i-abrasive ayilula ukuba i-blunt, kwaye ukuqina kwayo kungaphantsi kancinci kune-brown corundum. Iinkozo ze-abrasive ziqhekezwa ngokulula phantsi koxinzelelo ukuze zenze imiphetho entsha yokusika. Ngenxa yokuba i-abrasive inobulukhuni obuphezulu kune-corundum emdaka, kulula ukusika kwizinto zokusebenza, kwaye iinkozo ezinqabileyo zinomsebenzi wokuzilola, ngoko ke i-white corundum abrasive inamandla okusika, anokunciphisa i-deformation ye-workpiece kunye nokuveliswa kobushushu.

Ke ngoko, ii-abrasives ezimhlophe ze-corundum zilungele ukucolwa ngokuchanekileyo, ukulola, ukucolwa kwentambo, njl., kunye nokugaya izixhobo zokusebenza ezikhubazekayo ngokulula kwaye zitshiswe, njengokusila ngokuchanekileyo kwentsimbi eqinile, isinyithi esinesantya esiphezulu, isinyithi esinekhabhoni ephezulu, kunye nencinci. -amacandelo anezindonga. I-corundum emhlophe inesakhiwo se-micro-blade, esifanelekileyo kwisibuko sokugaya. Kwangaxeshanye, i-corundum emhlophe nayo ineempawu ze-asidi kunye ne-alkali yokumelana nokugqwala, ukumelana nobushushu obuphezulu, kunye nokuzinza okuhle kwe-thermal. Isetyenziswa kakhulu kwiinkalo zobuchwephesha obuphezulu ezifana nokuphosa ngokuchanekileyo, i-refractory yensimbi, i-refractory yeekhemikhali, ii-ceramics ezikhethekileyo, i-porcelain yokusetyenziswa kwemihla ngemihla, imboni yomkhosi kunye ne-electronics.

Umxholo we-sodium oxide kwi-corundum emhlophe eqhelekileyo iphakathi kwe-0.2 kunye ne-0.6%. Ubudlelwane phakathi kwe-white corundum powder kunye ne-alumina. I-sodium oxide yinto yokungcola eyingozi kwi-corundum emhlophe. Yenza i-β-Al2O3 kwimeko etyhidiweyo kunye ne-alumina, kwaye inani lokuqulunqa liyanda ngokunyuka kwe-sodium oxide content.

Ngophuhliso olukhawulezayo lweemarike ze-abrasives eziphezulu, ii-ceramics ze-elektroniki kunye nezixhobo ezichasayo eziphezulu, ukunciphisa umxholo we-sodium kwi-corundum emhlophe kuye kwaba lukhokelo olubalulekileyo lophando lokuphucula umgangatho we-corundum emhlophe. Kukho iindlela ezininzi zokususa i-sodium kwi-corundum emhlophe, njengokususa i-sodium kwizinto eziluhlaza, ukuthenga ngokuthe ngqo i-alumina ye-industrial e-low-sodium, okanye ukususa i-sodium kwi-alumina ephezulu ye-sodium. Amashishini okuvelisa ayisebenzisa kwiibhetshi kwizinga elikhulu.
