Emkhakheni wezinto eziphikisayo, i-corundum, njengezinto eziluhlaza ezibalulekile, isibe yinto esetshenziswa kabanzi embonini yokuphikisa ngenxa yezakhiwo zayo ezinhle kakhulu zomzimba nezamakhemikhali. Lesi sihloko sizokwethula izici eziyisisekelo, ukusetshenziswa okubanzi, isimo semakethe, kanye nenqubo yokukhiqiza i-corundum ngokuningiliziwe, futhi sigxile emshinini wokugaya osebenza kahle kakhulu we-corundum ongu-200-mesh ukuze sikutshele ukuthi uhola kanjani enkathini entsha yokugaya okuphumelelayo.

I-Corundum iyigugu elakhiwe yi-crystallization ye-aluminium oxide. Ubulukhuni bayo bungowesibili kuphela ngemva kwe-diamond ne-cubic boron nitride, kanti ubulukhuni bayo be-Mohs bufinyelela ku-9. Igama le-corundum livela eNdiya. Ingxenye yayo eyinhloko yi-Al₂O₃, futhi kunezinhlobo ezintathu: i-α-Al₂O₃、β-Al₂O₃、γ-Al₂O₃. Ngenxa yezakhiwo zayo ezinhle kakhulu zomzimba, i-corundum isetshenziswa kabanzi ezintweni zokugaya ezithuthukisiwe, amawashi, izinto zokuthwala imishini yokunemba, kanye neminye imikhakha.

Ukusetshenziswa kwe-corundum

Uhla lokusetshenziswa kwe-corundum lubanzi kakhulu, luhlanganisa amasimu amaningi ezimboni njenge-metallurgy, imishini, imboni yamakhemikhali, i-elekthronikhi, izindiza, kanye nokuvikela izwe. Ngenxa yokumelana kwayo nokushisa okuphezulu, ukumelana nokugqwala, kanye namandla aphezulu, i-corundum isetshenziswa njengesitsha sokuphehla iminyango eshelelayo yensimbi, ukuncibilikisa izinsimbi eziyigugu ezingavamile, kanye nama-alloy akhethekile; ezinhlelweni zamakhemikhali, i-corundum isetshenziswa njengemikhumbi ehlukahlukene yokusabela kanye namapayipi kanye nezingxenye zepompo yamakhemikhali; emkhakheni wemishini, i-corundum isetshenziselwa ukwenza imimese, isikhunta, izinto ezingangeni zinhlamvu, njll. Ngaphezu kwalokho, imikhiqizo ye-corundum esobala ingasetshenziswa futhi ukwenza izibani kanye nama-microwave fairing, kanti imikhiqizo ye-Na-b-Al₂O₃ iyizinto ze-electrolyte zokwenza amabhethri e-sodium-sulfur.

Isimo Semakethe yaseCorundum

Eminyakeni yamuva nje, ngokuthuthuka kwesayensi nobuchwepheshe kanye nentuthuko esheshayo yemboni, isidingo se-corundum siqhubekile nokukhula, futhi amathuba emakethe abanzi. I-China, i-India, ne-Brazil zingabakhiqizi abakhulu be-corundum emhlabeni, phakathi kwazo i-China ingumkhiqizi omkhulu futhi ithumela ngaphandle i-corundum emhlophe. Imakethe ye-corundum iveza isimo sokulinganisela okuyisisekelo phakathi kokuhlinzekwa kanye nesidingo, kanye nekhwalithi yomkhiqizo ethuthuka njalo kanye nezindawo zokusetshenziswa ezikhula njalo. Ikakhulukazi emikhakheni ephezulu njengokugaya nokupholisha okunembile kakhulu, ukusetshenziswa kwe-corundum kuya ngokuya kuba kubanzi.

Inqubo yokukhiqiza i-corundum

Inqubo yokukhiqiza i-corundum ihlanganisa izinyathelo eziningi ezifana nokulungiselela izinto, ukuncibilikisa, ukupholisa, ukwakheka kwekristalu kanye nokucubungula. Okokuqala, i-aluminium oxide powder ehlanzekile kakhulu iyahlolwa futhi yomiswe ukuqinisekisa ukufana kanye nobumsulwa bezinto zokusetshenziswa. Ngemuva kwalokho, i-aluminium oxide powder ifakwa esithandweni sikagesi bese ishiswa kuze kufike ekushiseni okuphezulu ukuze incibilike ibe yisimo soketshezi. Esimweni esincibilikisiwe, ama-molecule e-aluminium oxide azihlela kabusha ukuze akhe isakhiwo sekristalu futhi akhe izinhlayiya ze-corundum. Ngemuva kwalokho, izinga lokushisa lehliswa kancane kancane ukuze izinhlayiya ze-corundum ziqine kancane kancane zibe yinto eqinile. Ekugcineni, iyashiswa futhi ukuze kwenziwe isakhiwo sekristalu sizinze kakhudlwana futhi kuthuthukiswe ubulukhuni kanye nokumelana nokuguguleka kwe-corundum.

Isingeniso somshini wokugaya osebenza kahle kakhulu we-corundum ongu-200 mesh

Uma i-corundum isetshenziswa emikhakheni ethile, idinga ukugaywa ibe yi-200-mesh fine powder kuqala, njengezinto zokuzisusa zensimbi, izinto ze-ceramic zengilazi, kanye nezinto ezibonakalayo ze-semiconductor. Isinyathelo sokuqala sivame ukugaya. Ngalesi sikhathi, udinga ukusebenzisa umshini wokugaya we-200-mesh corundum osebenza kahle kakhulu. I-Guilin Hongcheng iyinkampani yasekhaya ethuthukisiwe yocwaningo nokuthuthukiswa kwemishini yokugaya kanye nokukhiqiza. I-HC series pendulum mill eyayithuthukisa iyisinqumo esifanele somshini wokugaya we-200-mesh corundum osebenza kahle kakhulu.

Ama-swing mill ochungechunge lwe-HC atholakala ngamamodeli ahlukahlukene, anemiphumela esukela ku-1 ton kuya ku-50 ton ngehora. Imishini izinzile lapho iqala ukusebenza, uhlelo lokucindezela olungeluhle lunesivalo esihle, indawo yokusebenza ihlanzekile futhi icocekile, ukulungiswa kwansuku zonke kulula, kanti izindleko zokusebenza nokugcinwa ziphansi. Isetshenziswa kabanzi embonini ephikisayo futhi isebenza kahle kakhulu.

Umshini wokugaya we-Guilin Hongcheng 200 mesh corundum osebenza kahle kakhulu kancane kancane uba yimishini ebalulekile emkhakheni wokucubungula amaminerali nokulungiselela izinto ngenxa yokusebenza kwawo kahle, ukonga amandla kanye nokuvikelwa kwemvelo. Njengento yokugaya esezingeni eliphezulu, isidingo semakethe se-corundum siyaqhubeka nokukhula futhi amathuba emakethe abanzi. Siyakwamukela ukuxhumana nathi ukuthola ikhotheshini yakamuva.
