Ngaba i-corundum emdaka ingathatha indawo ye-corundum emhlophe kwizixhobo zokurhawuzelela kunye nezixhobo zokugaya? ——Imibuzo neempendulo zolwazi
Q1: Yintoni i-corundum emdaka kunye ne-corundum emhlophe?
I-corundum emdakasisithambisi esenziwe nge-bauxite njengesixhobo esiphambili kwaye sinyibilikiswa kubushushu obuphezulu. Icandelo layo eliphambili yii-aluminium oxide(Al₂O₃), enomxholo omalunga ne-94% nangaphezulu, kwaye inomlinganiselo omncinci we-iron oxide kunye ne-silicon oxide. I-White corundum sisithambisi esicocekileyo kakhulu, kwaye eyona nto iphambili yi-aluminium oxide, kodwa icocekile kakhulu (malunga ne-99%) kwaye phantse ayinangcoliseko.
Umbuzo 2: Yintoni umahluko phakathi kwe-corundum emdaka kunye ne-corundum emhlophe ngobunzima kunye nokuqina?
Ubunzima: I-corundum emhlophe inobunzima obuphezulu kunoboi-corundum emdaka, ngoko ke ifanelekile ekucubunguleni izixhobo ezinobunzima obuphezulu. Ukuqina: I-corundum emdaka inobunzima obuphezulu kune-corundum emhlophe, kwaye ifanelekile kwiindawo ezineemfuno zokumelana noxinzelelo oluphezulu njengokusila okurhabaxa okanye ukusila okunzima.
Q3: Ziziphi iindawo eziphambili zesicelo se-brown corundum?
Ngenxa yokuqina kwayo okuphezulu kunye nobunzima obuphakathi, i-brown corundum isetyenziswa kakhulu kwi:ukugayaiindawo ezifana nokusila okurhabaxa kunye nokusila okunzima. Ukucutshungulwa kwezinto ezinobunzima obuphakathi, njengentsimbi, izinto ezibunjiweyo, kunye neenkuni. Ukupolisha kunye nokuqhumisa isanti, ingakumbi ukurhabaxa komphezulu.
Q4: Ziziphi iindlela eziqhelekileyo zokusetyenziswa kwe-corundum emhlophe?
Ngenxa yobunzima bayo obuphezulu kunye nobunyulu bayo obuphezulu, i-corundum emhlophe idla ngokusetyenziselwa: ukugaya nokupolisha ngokuchanekileyo, njengokucubungula iintsimbi ezinobunzima obuphezulu kunye nentsimbi engagqwaliyo. Ukucubungula izinto ze-elektroniki kunye neeseramikhi ezineemfuno eziphezulu zomphezulu. Amasimi okucubungula ngokuchanekileyo aphezulu afana nezixhobo zonyango kunye nezixhobo zokukhanya.
Umbuzo 5: Kukweziphi iimeko apho i-corundum emdaka inokuthi ithathe indawo ye-corundum emhlophe?
Iimeko apho i-corundum emdaka inokuthi ithathe indawoi-corundum emhlopheziquka: ubunzima bezinto ezicutshungulwayo buphantsi, kwaye ubunzima oburhabaxa akufuneki bube phezulu kakhulu. Iimfuno zokuchaneka kokucubungula aziphezulu, njengokusila okurhabaxa okanye ukususa izinto ezingafunekiyo. Xa iindleko zoqoqosho zilinganiselwe, ukusetyenziswa kwe-brown corundum kunokunciphisa kakhulu iindleko.
Umbuzo 6: Kukweziphi iimeko apho i-corundum emhlophe ingathathelwa indawo yi-corundum emdaka?
Iimeko apho i-corundum emhlophe ingenakutshintshwa yi-corundum emdaka ziquka: ukucutshungulwa ngokuchanekileyo kwezinto ezinobunzima obuphezulu, njengentsimbi enekhabhoni ephezulu kunye nentsimbi engatyiwayo. Ukucutshungulwa kweemeko ezineemfuno eziphezulu kakhulu zomphezulu, njengokucolwa kwesipili esibonakalayo. Izicelo ezinobuthathaka kukungcola okurhabaxa, njengezixhobo zonyango okanye ukucutshungulwa kwe-semiconductor.
Umbuzo 7: Yintoni umahluko phakathi kwexabiso le-corundum emdaka kunye ne-corundum emhlophe?
Izinto eziphambili ze-brown corundum kunye ne-white corundum zombini zilitye le-aluminium; kodwa ngenxa yeendlela ezahlukeneyo zokucubungula, iindleko zemveliso ye-brown corundum ziphantsi, ngoko ke ixabiso liphantsi kakhulu kune-white corundum. Kwiiprojekthi ezinebhajethi encinci, ukukhetha i-brown corundum sisisombululo esingabizi kakhulu.
Umbuzo 8: Ngamafutshane, ungayikhetha njani into efanelekileyo yokurhawuzelela?
Ukukhetha i-corundum emdaka okanye i-corundum emhlophe kufuneka kumiselwe ngokweemfuno ezithile:
Ukuba iimfuno zakho zokucubungula zithanda ukuba kukugaya okurhabaxa okanye ukulawula iindleko, kuyacetyiswa ukuba usebenzise i-corundum emdaka. Ukuba iimfuno zokuchaneka kokucubungula ziphezulu kwaye into yokucubungula yintsimbi enobunzima obuphezulu okanye iindawo ezichanekileyo, i-corundum emhlophe kufuneka ikhethwe. Ngokuhlalutya ngokufanelekileyo iimpawu zezi zimbini, unokufumana ibhalansi engcono phakathi kokusebenza kunye neendleko. Ukuba usenemibuzo, ungabonisana neengcali ngakumbi ngokwemeko yokwenyani yesicelo.
