Iinkalo zesicelo kunye neenzuzo zesanti ye-corundum emdaka
Isanti ye-corundum emdaka, eyaziwa ngokuba yi-brown corundum okanyebrown edityanisiweyo corundum, luhlobo lwe-abrasive eyenziweyo eyenziwe nge-bauxite ekumgangatho ophezulu njengeyona nto iphambili ekrwada, inyibilikiswa kwaye ipholiswe kubushushu obuphezulu obungaphezulu kwe-2000℃ kwiziko lombane le-arc. Icandelo eliphambili yi-aluminium oxide (Al₂O₃), kwaye umxholo ngokubanzi ungaphezulu kwe-95%. Ngenxa yokuqina kwayo okuphezulu, ukuqina okuhle, ukuxhathisa okuqinileyo kunye nokumelana nobushushu obuphezulu, isetyenziswa kakhulu kwiinkalo ezininzi zemizi-mveliso. Ngophuculo oluqhubekayo lweemfuno zokuchaneka kokulungiswa kwezinto, ukusetyenziswa kwesanti ye-corundum emdaka kwi-abrasives, izinto eziphikisayo, ukunyangwa kwendawo, ukuphosa kunye nezihlunu ezisebenzayo zibaluleka ngakumbi.
1. Ukusetyenziswa ngokubanzi kwiibrasives
I-Abrasives yenye yezona ndawo ziqhelekileyo kwaye zibalulekileyo zesicelo se-brown corundum. Ngenxa yokuqina kwayo kwe-Mohs ukuya kuthi ga kwi-9.0, okwesibini kuphela kwi-diamond kunye ne-silicon carbide, i-brown corundum isetyenziswa kakhulu ekwenzeni iimveliso ezahlukeneyo ezinqabileyo, ezifana namavili okusila, ilaphu le-emery, i-sandpaper, i-oilstones kunye neentloko zokusila. Nokuba kusetyenzwe ngesinyithi, ukupolisha kweglasi okanye ukugaya i-ceramic, i-brown corundum inokubonelela ngamandla okusika okusebenzayo kunye nokumelana nokunxiba kakuhle. Ngokukodwa kwiimeko zoshishino ezifuna ukusika okuqinileyo kunye nokugcinwa kwemilo ezinzileyo, i-brown corundum abrasives iqhuba kakuhle kakhulu.
2. Njengesixhobo esibalulekileyo semathiriyeli ye-refractory
I-Brown corundum inobushushu obuphezulu obuphezulu kunye nozinzo oluhle kakhulu lwe-thermal, ke isetyenziswa ngokubanzi ukwenza iimveliso ezahlukeneyo ezisebenza kakhulu. Kwiamaziko amashishini anobushushu obuphezuluezifana nesinyithi, isinyithi, i-samente, kunye neglasi, i-corundum emdaka ingasetyenziselwa ukuvelisa izitena eziphezulu ze-refractory, i-castables, iiplastiki, izinto ze-ramming kunye nezinye iimveliso eziphikisayo, ngokukodwa kwiindawo ezinobunzulu obuphezulu bokushisa kunye nokutshatyalaliswa rhoqo kwe-thermal. Xa kuthelekiswa nezinto zemveli ze-aluminiyam, i-brown corundum refractory ingcono ukukhukuliseka kwe-slag kunye nokuchasana kwe-spalling, ngokufanelekileyo ukwandisa ubomi benkonzo yezixhobo kunye nokunciphisa iindleko zokugcinwa kweshishini.
3. Isicelo kwiukuqhushumba kwesantikunye nonyango olungaphezulu
Isanti ye-brown corundum isetyenziswa ngokubanzi kwi-metal surface sandblasting ngenxa yobukhulu bamasuntswana afanayo, ubunzima obuphezulu kunye nobunzima obuphezulu. Ngethuba lenkqubo ye-sandblasting, i-brown corundum inokususa ngokufanelekileyo i-rust, isikali, i-peyinti endala yepeyinti, njl njl kumphezulu we-workpiece, kunye nokuphucula ukucoceka kwendawo kunye nokubambelela. Kwangaxeshanye, ngenxa yokuzilola kakuhle kwaye akukho lula ukudlula, inokuphinda isetyenziswe kwaye isetyenziswe ngamaxesha amaninzi, ukunciphisa kakhulu iindleko zezinto eziphathekayo. Ukongeza, i-brown corundum ikwabonisa iziphumo ezizodwa kunyango lwe-matte kunye nokulungiswa komphezulu wokuthungwa kwezinto ezifana nentsimbi engenasici, iiprofayili ze-aluminium, iglasi kunye neekeramics.
4. Ukusetyenziswa kokuphosa ngokuchanekileyo
Kwiminyaka yakutshanje, ngophuhliso oluqhubekayo lwetekhnoloji yokuphosa echanekileyo, iimfuno eziphezulu zibekwe phambili ukucoceka kunye nokuzinza kwe-thermal yezinto zokuphosa.I-brown corundum iye yaba yinto efanelekileyo yegobolondo ye-castings echanekileyo efana ne-alloys ephezulu yokushisa, insimbi engenasici, kunye ne-carbon steel ngenxa yokwakheka kweekhemikhali ezizinzile, ukuhanjiswa kakuhle kwe-thermal, kunye ne-coefficient ephantsi yokwandisa i-thermal. I-brown corundum yokuphosa isanti inokuphucula ngokufanelekileyo umgangatho wendawo yokuphosa kunye nokunciphisa iziphene zokuphosa. Isetyenziswa kakhulu kwiindawo zokuvelisa ezikumgangatho ophezulu ezinje ngenqwelomoya, iimoto, kunye namandla.
5. Ukusetyenziswa okwandisiweyo njengefayili esebenzayo
I-corundum ye-Brown ingaphinda isetyenziswe njenge-aggregate esebenzayo kwiimveliso ezifana ne-anti-slip floors, i-pavements engaguqukiyo, i-resin mortars, kunye nezinto zokwakha eziphezulu. Ubunzima bayo obugqwesileyo kunye nokunyanzeliswa koxinzelelo kunceda ukuphucula ukunyanzeliswa kokugqoka kunye nobomi benkonzo yezinto ezidibeneyo. Kwimimandla ye-electronics, i-ceramics, i-rubber, njl., i-brown corundum micropowder iphinda isetyenziswe njengento yokuzalisa ukuphucula ukuxhathisa ukushisa, ukuqhutyelwa kwe-thermal, kunye namandla okwakhiwa kwemveliso.
Ukuqukumbela
Isanti ye-corundum emdaka idlala indima ebaluleke kakhulu kwishishini lanamhlanje kunye neempawu zayo ezintle zomzimba kunye nokuzinza kweekhemikhali. Ngophuculo lwetekhnoloji yemathiriyeli kunye neemfuno zokusetyenzwa kwemizi-mveliso, ithemba lentengiso yesanti ye-corundum emdaka iya kuba banzi kwaye iya kuzisa nezisombululo ezisebenzayo nezinobuhlobo kokusingqongileyo kumashishini amaninzi.
