Intshayelelo kunye nokusetyenziswa kwe-diamond abrasives
Idayimani yinto enobona bunzima kwindalo. Inobunzima obuphezulu kakhulu, i-thermal conductivity kunye nokumelana nokunxiba, ngoko ke isetyenziswa ngokubanzi kwishishini le-abrasive. Ngophuhliso lobuchwephesha boshishino,iibrasives zedayimaniziye zaphuhliswa ukusuka kwidayimani zendalo zendalo ukuya kwiidayimani ezahlukeneyo ezenziweyo kunye nezixhobo ezisebenzayo ezidibeneyo, zibe yinxalenye ebalulekileyo yentsimi yezinto ezilukhuni, kwaye zisetyenziswa ngokubanzi kumashishini amaninzi achanekileyo afana nokulungiswa koomatshini, i-electronics, optics, kunye namandla amatsha.
Ⅰ. Intshayelelo esisiseko yeebrasives zedayimani
Iibrasives zedayimani ziumgubo okanye izixhobo zegranular eyenziwe ngokutyumza, ukuhluzwa, kunye nokucocwa kweedayimani zendalo okanye iidayimani ezenziweyo. Ubulukhuni bayo be-Mohs bufikelela kwinqanaba le-10, eyona nto iphakamileyo eyaziwayo. Xa kuthelekiswa ne-abrasives yendabuko efana ne-aluminium oxide kunye ne-silicon carbide, i-diamond abrasives inamandla aphezulu okusika kunye nokumelana nokunxiba, kwaye inokugaya kunye nokupolisha izinto ezinobunzima obuphezulu kunye nomonakalo ophantsi.
Iziqhoboshi zedayimani ikakhulu ziquka ezi fomu zilandelayo:
Diamond micropowder: Ubungakanani bamaqhekeza busuka kwishumi le-microns ukuya kwii-nanometers, ezifanelekileyo kwiinkqubo ezahlukeneyo zokuchaneka okuphezulu.
Ivili lokusila idayimane / intloko yokusila: isetyenziselwa ukugaya kunye nokubunjwa kwezinto ezinzima.
Idayimani isarha iblade/intwana yokomba: isetyenziselwa ukusika kunye nokugrumba izinto ezifana nelitye, iiseramikhi, iglasi, njl.
Ulwelo lokusila idayimani / uncamathiselo lokupholisha: lusetyenziswa ngokubanzi kwi-ultra-precision processing kwi-electronics, optics, ukungunda kunye namanye amashishini.
Izinto zedayimani ezihlanganisiweyo (i-PCD/PCBN): idibanisa idayimani ngesinyithi okanye i-ceramic matrix ukwenza isixhobo esixubileyo sesixhobo esinobunzima kunye nokumelana nokunxiba.
Ⅱ. Iinkalo zokusetyenziswa kwe-diamond abrasives
1. Ukulungiswa koomatshini
I-abrasives yedayimani isetyenziswa ngokubanzi ekubunjweni nasekusikeni kwezinto ezinobunzima obuphezulu, njenge-carbide enesamente, iiseramikhi, i-silicon carbide, iglasi, i-ferrite, njl.njl. Ukusebenzisa amavili edayimani okusila ukusetyenzwa akunakuphucula kakhulu ukusebenza kakuhle kunye nomgangatho womphezulu, kodwa ukwandiswa kobomi besixhobo kunye nokunciphisa isixhobo sokutshintsha rhoqo. Ilungele ngokukodwa ukuveliswa kobuninzi, iinkqubo ezizenzekelayo ezichanekileyo zokuvelisa.
2. Amashishini ombane kunye ne-semiconductor
Ngexesha lokusetyenzwa kwemathiriyeli enje ngee-silicon wafers, i-sapphire substrates, i-silicon carbide chips, iglasi ye-optoelectronic, njl. Iibrasives zedayimani zinokufikelela kwi-submicron okanye nakwi-nanometer-level flatness kunye noburhabaxa. Zisetyenziswa ngokubanzi kumakhonkco abalulekileyo afana ne-chip dicing, i-wafer grinding, kunye nokupolisha i-photomask. Ziyinto ebalulekileyo ekuqinisekiseni ukusebenza okuphezulu kunye nesivuno esiphezulu seemveliso ze-elektroniki.
3. Ukulungiswa kwamehlo
Umgubo wedayimani usetyenziswa kakhulu ekuhonjisweni kweglasi yokukhanya, iifestile zelaser, iilensi zesafire kunye namanye amacandelo. Amandla ayo okusika okugqwesileyo kunye nokuzinza kweekhemikhali kunokuphucula ngokufanelekileyo umgangatho wokulungiswa kwesibuko kunye nokufezekisa uburhabaxa bomhlaba uRa ongaphantsi kwe-10nm. Yimathiriyeli ebalulekileyo yokuphumeza imiphezulu egudileyo kunye nokuhanjiswa kokukhanya okuphezulu.
4. Ukwakhiwa kunye nokulungiswa kwamatye
I-Diamond saw blades, i-drill bits, iingcingo zokusika, njl.njl. zisetyenziswa ngokubanzi ekusetyenzweni kwezixhobo zokwakha ezifana negranite, ibhastile, kunye nekhonkrithi. Xa kuthelekiswa nezixhobo zemveli, izixhobo zedayimane ziphezulu kwisantya sokusika, ubomi benkonzo, kunye nomgangatho wokusika, kwaye zifaneleke ngokukhethekileyo ukucubungula ngokufanelekileyo kwezinto zokwakha zamandla aphezulu kunye nobuninzi.
5. Amandla amatsha kunye ne-aerospace
Ngophuhliso lwetekhnoloji yamandla amatsha, imfuno yee-abrasives zedayimane ekusetyenzweni kweeplanga zebhetri ye-lithium, i-ceramic diaphragms, izinto zemoto yombane, njl.njl ikhula ngokukhawuleza. Kwintsimi ye-aerospace, izixhobo zedayimane zisetyenziselwa ukuchaneka ngokuchanekileyo kwe-injini yamacandelo ashushu ashushu, iindawo ezidibeneyo zesakhiwo, njl., Okuphucula ukuthembeka kunye nokuqina kweemveliso.
III. Ukuqukumbela
Iibrasives zedayimani, njengesixhobo esisisiseko esibalulekileyo sokwenziwa kwemizi-mveliso yale mihla, zamkelwa ziimeko zoomatshini ezichaneke ngakumbi ngenxa yeempawu zazo zomzimba ezibalaseleyo kunye nokusebenza okubanzi. Kwixesha elizayo, kunye nokuqhubela phambili okuqhubekayo kwezinto zesayensi kunye neteknoloji yokuvelisa, i-abrasives yedayimane iya kuqhubeka nokuphuhliswa kwindlela ecocekileyo, ehlakaniphile kunye neyobume bendalo, inceda imboni yemveliso ephezulu ukuya kwinqanaba eliphezulu.
