Ngaba i-corundum emdaka ingathatha indawo ye-corundum emhlophe kwi-abrasives kunye nezixhobo zokusila? —— Imibuzo Neempendulo Zolwazi

I-Q1: Yintoni i-corundum emdaka kunye ne-corundum emhlophe?

I-brown corundumsisiqhumiso esenziwe nge-bauxite njengesona sixhobo siphambili ekrwada kwaye sinyibilikiswa kubushushu obuphezulu. Icandelo layo eliphambili lii-aluminium oxide(Al₂O₃), enomxholo malunga ne-94% okanye ngaphezulu, kwaye iqulethe i-iron oxide encinci kunye ne-silicon oxide. I-corundum emhlophe i-abrasive-purity abrasive, kunye necandelo layo eliphambili liphinde libe yi-aluminium oxide, kodwa ngococeko oluphezulu (malunga ne-99%) kwaye phantse akukho kungcola.

I-Q2: Uthini umahluko phakathi kwe-corundum emdaka kunye ne-corundum emhlophe ngobunzima kunye nobunzima?

Ubunzima: I-corundum emhlophe inobunzima obuphezulu kunokoi-brown corundum, ngoko ifanelekile ukucubungula izinto ezinobunzima obuphezulu. Ukuqina: I-brown corundum inokuqina okuphezulu kune-corundum emhlophe, kwaye ifanelekile kwimiboniso eneemfuno zokumelana nempembelelo ephezulu njengokusila ngokurhabaxa okanye ukugaya kakhulu.

I-Q3: Ziziphi iindawo eziphambili zesicelo se-brown corundum?

Ngenxa yokuqina kwayo okuphezulu kunye nobunzima obuphakathi, i-corundum emdaka isetyenziswa kakhulu:ukusilaimiboniso efana nokusila ngokurhabaxa kunye nokusila kakhulu. Ukulungiswa kwezinto ezinobulukhuni obuphakathi, njengentsimbi, ukubunjwa, kunye neenkuni. Ukukhazimliswa kunye nokuqhunyiswa kwesanti, ngakumbi ukurhaxa komhlaba.

I-Q4: Ziziphi izicelo eziqhelekileyo ze-corundum emhlophe?

Ngenxa yobunzima bayo obuphezulu kunye nokucoceka okuphezulu, i-corundum emhlophe isoloko isetyenziselwa: ukugaya ngokuchanekileyo kunye nokupolisha, njengokucutshungulwa kwentsimbi ephezulu kunye nensimbi engenasici. Ukulungiswa kwezinto ze-elektroniki kunye neekeramics ezineemfuno eziphezulu eziphezulu. Iinkalo zokulungisa ezichanekileyo ezifana nezixhobo zonyango kunye nezixhobo zokukhanya.

I-Q5: Kweziphi iimeko apho i-corundum emdaka ingathatha indawo ye-corundum emhlophe?

Iimeko apho i-corundum emdaka inokutshintsha indawocorundum emhlophezibandakanya: ubunzima bezinto ezicutshungulwayo ziphantsi, kwaye ukuqina kwe-abrasive akufuneki ukuba kuphakame ngokukodwa. Iimfuno zokuchaneka kokusetyenzwa azikho phezulu, njengokusila ngokurhabaxa komhlaba okanye ukugxothwa. Xa iindleko zoqoqosho zilinganiselwe, ukusetyenziswa kwe-brown corundum kunokunciphisa kakhulu iindleko.

I-Q6: Kweziphi iimeko apho i-corundum emhlophe ayinakutshintshwa yi-brown corundum?

Iimeko apho i-corundum emhlophe ayinakutshintshwa yi-brown corundum ibandakanya: ukulungiswa ngokuchanekileyo kwezinto ezinobunzima obuphezulu, ezifana ne-carbon steel high and stainless steel. Ukusetyenzwa kweemeko ezineemfuno eziphezulu kakhulu zomphezulu, ezinje ngokugudiswa kwesipili esibonakalayo. Usetyenziso olunobuntununtunu kukungcola okurhawukayo, okufana nezixhobo zonyango okanye ukusetyenzwa kwe-semiconductor.

I-Q7: Uthini umahluko phakathi kweendleko phakathi kwe-brown corundum kunye ne-white corundum?

Izixhobo eziphambili ze-brown corundum kunye ne-white corundum zombini ngamatye e-aluminium; kodwa ngenxa yeendlela ezahlukeneyo zokucubungula, iindleko zokuvelisa i-brown corundum ziphantsi, ngoko ke ixabiso liphantsi kakhulu kune-corundum emhlophe. Kwiiprojekthi ezinohlahlo lwabiwo-mali olulinganiselweyo, ukukhetha i-brown corundum sisisombululo esinoqoqosho ngakumbi.

I-Q8: Isishwankathelo, indlela yokukhetha i-abrasive efanelekileyo?

Ukukhethwa kwe-brown corundum okanye i-corundum emhlophe kufuneka kugqitywe ngokweemfuno ezithile:
Ukuba iimfuno zakho zokusetyenzwa zithande ukugawula ngokurhabaxa okanye ulawulo lweendleko, kuyacetyiswa ukuba usebenzise i-brown corundum. Ukuba iimfuno zokuchaneka kokucubungula ziphezulu kwaye into yokucubungula iyintsimbi 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 ngokweyona meko yesicelo.
