Ziziphi iindlela eziphambili zokusebenzisa i-white corundum micropowder?
Umgubo omncinci we-corundum omhlophesisiqholo esibaluleke kakhulu nesinokusetyenziswa ngeendlela ezininzi. Iindlela zaso eziphambili zokusetyenziswa zahlulwe zibe ziindidi ezahlukeneyo:
1. Isicelo esingundoqo: UkuchanekaUkusila nokupolisha
Le yeyona ndlela isetyenziswa kakhulu kwaye iphambili ye-white corundum micropowder. Ngenxa yobunzima bayo obuphezulu, ubungakanani obufanayo beesuntswana, kunye nokumelana nokuguguleka okugqwesileyo, ivumela ulawulo oluchanekileyo kunye nokugqitywa komphezulu okugudileyo.
Ukusebenza ngesinyithi:
Ishishini leMold: Lisetyenziselwa ukupolisha iimold ezichanekileyo kakhulu (ezifana neemold zeglasi, iimold ze-injection, kunye neemolds ezisebenzisa i-die-casting), ukususa umaleko omhlophe (umaleko owonakeleyo) emva komatshini we-EDM ukuze kugqitywe isibuko.
I-Aerospace kunye neeMoto: Ukupolisha izinto ezibalulekileyo ezichanekileyo ezifana neebhlade zenjini, iidiski zeturbine, kunye neempumlo zepetroli ukuqinisekisa umgangatho womphezulu kunye nokumelana nokudinwa.
Izixhobo zonyango: Izixhobo zotyando zokupolisha, izixhobo zokufakelwa kwamathambo (ezifana namalungu okwenziwa), kunye nezixhobo zamazinyo, ezifuna ukugqitywa okuphezulu kakhulu komphezulu kunye nokuhambelana kwezinto eziphilayo.
Ukucubungula Izinto Ezibonakalayo:
Isetyenziselwa ukugaywa nokupholishwa kakuhle kwezinto zeglasi okanye zekristale ezifana neelensi, iiprism, kunye nezibuko, ilawula ngokufanelekileyo ukuchaneka komphezulu kwaye inciphise iziphene zomphezulu.
Ishishini leSemiconductor kunye ne-Electronics:
Ukwenziwa kweWafer: Isetyenziselwa ukuncitshiswa ngasemva kunye nokupholisha imiphetho yeewafer zesilicon.
Ukupakishwa kweetshiphusi: Kusetyenziselwa ukugawula iileya ze-oxide kunye nezesinyithi ukuze kuthambe umphezulu weetshiphusi (nangona inkqubo ye-CMP eqhelekileyo ngoku isebenzisa i-silica kunye ne-cerium oxide slurry, i-white corundum isasetyenziswa).
Isetyenziselwa ukupolisha izinto zemagnethi, ii-ceramic substrates, iikristale ze-piezoelectric, kunye nezinye izinto ze-elektroniki.
Ukulungiswa kweZacholo:
Isetyenziselwa ukupholisha nokulungisa izinyithi ezixabisekileyo (igolide, isilivere, iplatinum) kunye namatye anqabileyo, nto leyo efumana ukukhanya okuphezulu kakhulu.
2. NjengoMzalisi oSebenzayo
Ukusebenzisa ubulukhuni bayo obuphezulu, ukumelana nokuguguleka, ukumelana nobushushu, kunye nokuzinza kweekhemikhali,umgubo omhlophe we-corundum yongezwa kwizinto ezahlukeneyo ukuphucula iimpawu zayo.
Iingubo kunye nomgangatho onganyangekiyo:
Ukongeza kwi-epoxy resins, i-polyurethane, kunye nezinye izinto zomgangatho, idala umgangatho wemizi-mveliso onganyangekiyo kakhulu ukuze usetyenziswe kwiindawo zokugcina impahla, kwiindawo zokusebenzela, kwiindawo zokupaka, nakwezinye iindawo ezithwaxwa yimithwalo enzima kunye nokungqubana rhoqo.
Isetyenziswa njengesixhobo sokudibanisa izinto zokutshiza okanye zokugquma ukuze kuphuculwe ukuguguleka kunye nokumelana nokugqwala kwemiphezulu yezinto zokusebenza.
Izixhobo eziPhambili zokuKhangela:
Njengesongezelelo esibalulekileyo, isetyenziswa ekwenzeni izinto ezisetyenziswa kwi-ladle castables, izinto ze-iron channel, ii-ceramics ezichasene ne-refractory, nokunye. Iphucula kakhulu amandla, ukumelana nokugqwala, kunye nokuzinza kobushushu bezinto ezichasene ne-refractory.
Iimveliso zeCeramic:
Ukongeza kwi-ceramics zesakhiwo (ezifana ne-alumina ceramics kunye ne-silicon carbide ceramics) njengesigaba sokuqinisa, kwandisa ukuqina, ubulukhuni, kunye nokumelana nokuguguleka kwe-ceramics.
Izixhobo Zokugaya Nokugawula:
Ukuvelisa izinto zokuqhobosha ezibotshelelweyo ezifana namavili okugaya abotshelelweyo e-resin, iibhanti zokuqhobosha, iphepha lokusanti, kunye namatye eoyile.
Ekwenzeni izixhobo ezifana neeblade zesarha yedayimani kunye namavili okugaya, yongezwa njengesiqholo esingesiso esiphambili kwintloko yokusika ukunceda ekususweni kweetshiphusi kunye nokuphucula ukusebenza kakuhle kokusika.
Ezinye Izinto Ezidityanisiweyo:
Xa yongezwa kwiplastiki nerabha, inokuphucula ukuhanjiswa kobushushu, ukumelana nokuguguleka, kunye nokuqina kweemveliso. Umzekelo, isetyenziswa ekwenzeni iibrake pads ezisebenza kakuhle kunye nezinto zokungqubana.
3. Ukuqhumisa isanti kunye nonyango lomphezulu: Ukuqhumisa isanti okumanzi:
I-white corundum micropowder ixutywa namanzi ukwenza i-slurry esetyenziselwa ukucoca umphezulu, ukususa iimbumbulu, kunye nokugqiba iindawo ezichanekileyo. Xa kuthelekiswa ne-sandblasting eyomileyo, i-sandblasting emanzi inika ulawulo olungcono lokurhabaxa komphezulu, inciphisa uthuli, kwaye ayinampembelelo ingako kwindawo yokusebenza, ithintela ukuguquguquka.
Ukuqhuma kwesanti okomileyo:
Nangona amasuntswana e-corundum amhlophe aqinileyo esetyenziswa kakhulu, iipowders ezenziwe nge-micron zingasetyenziselwa unyango lomphezulu olufuna iinkcukacha ezincinci kakhulu, njengokucoca nokulungisa iindawo zesinyithi ezinobuthathaka.
4. Ezinye izicelo ezikhethekileyo
Iibheringi zeZixhobo ezichanekileyo:
Isetyenziselwaukupolisha nokugqibaiibheringi zelitye elinqabileyo (ezifana neebheringi ze-agate) kwiiwotshi ezikumgangatho ophezulu.
Uphando kunye novavanyo:
Kwiilabhoratri zesayensi yezinto, ukuqhumisa isanti okumanzi kusetyenziswa ukulungiselela iisampulu ze-metallographic, nto leyo etyhila ngokucacileyo ulwakhiwo lwezixhobo zesinyithi ngokusila nokupolisha.
Isishwankathelo seempawu (Isizathu sokuba zisetyenziswe kakhulu kwezi nkalo):
Ubunzima Obuphezulu: Ngobunzima be-Mohs obuyi-9, obulandela idayimani kunye ne-silicon carbide kuphela, ukuqhumisa isanti okumanzi kuvumela ukugaywa kakuhle kwezinto ezininzi.
Ubungakanani beParticle obufanayo: Ukuhlelwa ngokuchanekileyo kuphumela ekusasazweni kobukhulu beparticle obuqinileyo, okuqinisekisa iziphumo zokucubungula ezihambelanayo nezilawulekayo.
Ukumelana nokuNxiba Okugqwesileyo: Ukuguguleka okuphantsi ngexesha lokusetyenziswa, okubangela ubomi benkonzo ende.
Uzinzo Oluphezulu Lweekhemikhali: Ayisebenzi ngokweekhemikhali kunye nomsebenzi, nto leyo eyenza ukuba ifaneleke ngakumbi ekucubunguleni iintsimbi ezisabelayo ezifana nentsimbi engagqwaliyo kunye nee-alloys ze-titanium.
Ukumelana nobushushu obuphezulu: Igcina ukusebenza kakuhle nakwiindawo ezinobushushu obuphezulu.
Ucoceko Oluphezulu: Ubungakanani obuphantsi bokungcola, ukuqinisekisa ukuba akukho ngcoliseko kumphezulu wezinto zokusebenza ngexesha lokwenziwa.
