Amasimi okusetyenziswa kunye neenzuzo zesanti emdaka ye-corundum
Isanti ye-corundum emdaka, okwaziwa ngokuba yi-brown corundum okanyei-corundum emdaka edibeneyo, luhlobo lwe-abrasive yokwenziwa eyenziwe nge-bauxite ekumgangatho ophezulu njengezinto eziphambili zokwenza, ezinyibilikisiweyo zaza zapholiswa kubushushu obuphezulu obungaphezulu kwama-2000℃ kwisithando sombane se-arc. Icandelo eliphambili yi-aluminium oxide (Al₂O₃), kwaye umxholo ngokubanzi ungaphezulu kwama-95%. Ngenxa yobunzima bayo obuphezulu, ukuqina okuhle, ukumelana nokuguguleka okunamandla kunye nokumelana okuphezulu kobushushu obuphezulu, isetyenziswa kakhulu kwiindawo ezininzi zoshishino. Ngokuphucuka okuqhubekayo kweemfuno zokuchaneka kokucubungula izinto, ukusetyenziswa kwesanti ye-corundum emdaka kwi-abrasives, izinto ezichasayo, unyango lomphezulu, i-casting kunye ne-functional fillers kuya kuba yimfuneko ngakumbi.
1. Ukusetyenziswa ngokubanzi kwiibrasives
Ii-abrasives zezinye zezona ndawo zisetyenziswa kakhulu kwi-brown corundum. Ngenxa yobunzima bayo be-Mohs obufikelela kwi-9.0, obulandela i-diamond kunye ne-silicon carbide, i-brown corundum isetyenziswa kakhulu ekwenzeni iimveliso ezahlukeneyo ze-abrasive, ezinje ngamavili okugaya, ilaphu le-emery, iphepha lesanti, amatye eoyile kunye neentloko zokugaya. Nokuba kusetyenzwa ngesinyithi, ukupolisha iglasi okanye ukugaya nge-ceramic, i-brown corundum inokubonelela ngamandla okusika ngokufanelekileyo kunye nokumelana nokuguguleka okuhle. Ingakumbi kwiimeko zoshishino ezifuna ukusika okuqinileyo kunye nokugcinwa kwesimo esizinzileyo, ii-brown corundum abrasives zisebenza kakuhle kakhulu.
2. Njengezinto ezibalulekileyo zokwenza izinto ezingafunekiyo
I-corundum emdaka inobushushu obuphezulu kakhulu bokuchasana nobushushu kunye nozinzo oluhle kakhulu lobushushu, ngoko ke isetyenziswa kakhulu ukuvelisa iimveliso ezahlukeneyo zokuchasana nobushushu ezisebenza kakuhle.izitofu zoshishino ezishushu kakhuluEzifana ne-metallurgy, intsimbi, isamente, kunye neglasi, i-brown corundum ingasetyenziselwa ukuvelisa izitena ezirhabaxa ezikumgangatho ophezulu, izinto eziphoswayo, iiplastiki, izinto zokugquma kunye nezinye iimveliso ezirhabaxa, ingakumbi kwiindawo ezinobushushu obuphezulu kunye nokutshayiswa rhoqo kobushushu. Xa kuthelekiswa nezinto zemveli ze-aluminium ephezulu, izinto ezirhabaxa ze-brown corundum zinokukhukuliseka okungcono kwe-slag kunye nokumelana nokuqhekeka, nto leyo eyandisa ubomi benkonzo yezixhobo kwaye inciphisa iindleko zokugcinwa kweshishini.
3. Isicelo kwiukuqhumisa isantikunye nonyango lomphezulu
Isanti ye-corundum emdaka isetyenziswa kakhulu kwi-sandblasting yesinyithi ngenxa yobukhulu bayo obufanayo, ubulukhuni obuphezulu kunye nomxhuzulane ophezulu. Ngexesha lenkqubo yokuqhumisa isanti, i-corundum emdaka inokususa ngokufanelekileyo umhlwa, isikali, umaleko wepeyinti endala, njl.njl. kumphezulu wesixhobo somsebenzi, kwaye iphucule ukucoceka komphezulu kunye nokunamathela. Kwangaxeshanye, ngenxa yokuzilola kwayo kakuhle kwaye kulula ukuyithambisa, inokuphinda isetyenziswe kwaye isetyenziswe amaxesha amaninzi, nto leyo enciphisa kakhulu iindleko zezinto. Ukongeza, i-corundum emdaka ikwabonisa iziphumo ezizodwa kunyango lwe-matte kunye nokulungiswa kobume bomphezulu wezinto ezifana nentsimbi engagqwaliyo, iiprofayili ze-aluminium, iglasi, kunye neeseramikhi.
4. Ukusetyenziswa ekubunjweni ngokuchanekileyo
Kwiminyaka yakutshanje, ngophuhliso oluqhubekayo lwetekhnoloji yokusika ngokuchanekileyo, kuye kwabekwa phambili iimfuno eziphezulu zokucoceka nokuzinza kobushushu bezinto zokusika.I-corundum emdaka iye yaba yinto efanelekileyo yeqokobhe lokwenza izinto ezichanekileyo ezifana nee-alloys ezinobushushu obuphezulu, intsimbi engagqwaliyo, kunye nentsimbi yekhabhoni ngenxa yokwakheka kwayo okuzinzileyo kweekhemikhali, ukuqhuba kakuhle kobushushu, kunye ne-coefficient yokwandisa ubushushu obuphantsi. Isanti yokuphosa i-corundum emdaka inokuphucula ngokufanelekileyo umgangatho womphezulu wezinto eziphosayo kwaye inciphise iziphene zokuphosa. Isetyenziswa kakhulu kwiindawo zokuvelisa eziphezulu ezifana neenqwelo moya, iimoto, kunye namandla.
5. Ukusetyenziswa ixesha elide njengesizalisi esisebenzayo
I-brown corundum ingasetyenziswa njengesixhobo esisebenzayo kwiimveliso ezifana nee-anti-slip floors, ii-pavements ezinganyangekiyo, ii-resin mortars, kunye nezixhobo zokwakha eziphezulu. Ubulukhuni bayo obuhle kunye nokumelana nokucinezelwa kunceda ukuphucula ukumelana nokuguguleka kunye nobomi benkonzo yezinto ezidityanisiweyo. Kwimimandla ye-elektroniki, ii-ceramics, irabha, njl.njl., i-brown corundum micropowder ikwasetyenziswa njengesizalisi ukuphucula ukumelana nobushushu, ukuqhuba kobushushu, kunye namandla olwakhiwo lwemveliso.
Isiphelo
Isanti ye-corundum emdaka idlala indima ebalulekileyo kushishino lwanamhlanje ngenxa yeempawu zayo ezibonakalayo ezintle kunye nozinzo lweekhemikhali. Ngokuphuculwa kwetekhnoloji yezinto eziphathekayo kunye neemfuno zokucubungula imboni, amathuba emarike esanti ye-corundum emdaka aya kuba maninzi kwaye aya kuzisa izisombululo ezisebenzayo nezinobuhlobo nokusingqongileyo kumashishini amaninzi.
