Ukupholisha Nokugaya Izakhiwo zeNano Silicon Carbide

I-Nano Silicon carbide powder(HW-D507) ikhiqizwa ngokuncibilikisa isihlabathi se-quartz, i-petroleum coke (noma i-coke yamalahle), kanye nama-wood chips njengezinto zokusetshenziswa ngokusebenzisa izinga lokushisa eliphezulu ezithandweni zokumelana. I-silicon carbide nayo ikhona emvelweni njenge-mineral engajwayelekile- ebizwa ngokuthi i-moissanite. Kubuchwepheshe obuphezulu be-refractory izinto zokusetshenziswa ezifana ne-C, N, B nezinye i-non-oxide, i-silicon carbide iyona esetshenziswa kakhulu futhi iyonga kakhulu.

β-SiC powderinezakhiwo ezinjengokuqina kwamakhemikhali aphezulu, ubulukhuni obuphezulu, ukuqhutshwa kwe-thermal high, i-coefficient ephansi yokwandisa okushisayo nokunye. Ngakho-ke, inokusebenza okuhle kakhulu okufana ne-anti-abrasion, ukumelana nokushisa okuphezulu nokumelana nokushisa okushisayo. I-silicon carbide ingenziwa ibe izimpushana ezilumayo noma amakhanda okugaya ukuze kugaywe ngokunemba okuphezulu nokupholishwa kwezinto ezifana nezinsimbi, izitsha zobumba, ingilazi namapulasitiki. Uma kuqhathaniswa nezinto zendabuko zokuthuthumela, i-SiC inokumelana nokugqoka okuphezulu, ubulukhuni nokuzinza kokushisa, okungathuthukisa ngokuphumelelayo ukunemba kokucubungula nokusebenza kahle. Ngaphezu kwalokho, inokumelana okuhle kakhulu kwamakhemikhali kanye nokuzinza kwezinga lokushisa eliphezulu, ngakho-ke inamathuba amaningi okufaka isicelo emikhakheni ehlukahlukene.

I-SiC ingasetshenziswa ukulungisa izinto zokupholisha, ezinohlu olubanzi lwezinhlelo zokusebenza kubunjiniyela bemishini, amadivaysi kagesi, amadivaysi okukhanya neminye imikhakha. Le nto yokupholisha inezakhiwo ezinhle kakhulu njengokuqina okuphezulu, ukumelana nokugqoka okuphezulu kanye nokuzinza kwamakhemikhali aphezulu, okungafeza imisebenzi yekhwalithi ephezulu yokupholisha nokugaya. Okwamanje, izinto eziyinhloko zokugaya nokupholisha idayimane emakethe, futhi intengo yayo ingamashumi noma ngisho namakhulu ezikhathi ze-β-Sic. Nokho, umphumela wokugaya we-β-Sic emikhakheni eminingi awukho ngaphansi kwedayimane. Uma kuqhathaniswa namanye ama-abrasive anosayizi ofanayo wezinhlayiyana, i-β-Sic inokusebenza okuphakeme kakhulu kokucubungula nokusebenza kwezindleko.

Njengempahla yokupholisha nokugaya, i-nano silicon carbide nayo ine-coefficient ephansi yokungqubuzana okuhle kakhulu kanye nezakhiwo ezinhle kakhulu zokubona, ezisetshenziswa kabanzi ekucubunguleni i-microelectronic kanye nokukhiqizwa kwedivayisi ye-optoelectronic. I-Nano silicon carbide polishing kanye nezinto zokugaya zingafinyelela amakhono aphezulu kakhulu wokupholisha, kuyilapho kulawula futhi kunciphisa ukugwedla kwendawo kanye ne-morphology, kuthuthukisa izinga eliphezulu lempahla nokusebenza komkhiqizo.

Kumathuluzi edayimane asekelwe ku-resin, i-nano silicon carbide iyisengezo esibalulekile esingathuthukisa ngempumelelo ukumelana nokugqokwa, ukusika nokusebenza kokupholisha kwamathuluzi edayimane asekelwe ku-resin. Ngaleso sikhathi, usayizi omncane nokuhlakazeka okuhle kwe-SiC kungathuthukisa ukusebenza kwamathuluzi edayimane asekelwe ku-resin ngokuxuba kahle nezinto ezisekelwe ku-resin. Inqubo ye-nano SiC yokwenza amathuluzi edayimane asekelwe ku-resin ilula futhi kulula. Okokuqala, i-nano SiC powder ixubene ne-resin powder ngesilinganiso esinqunyiwe, bese iyashiswa futhi icindezelwe ngesikhunta, esingaqeda ngokuphumelelayo ukusatshalaliswa okungalingani kwezinhlayiya zedayimane ngokusebenzisa impahla yokuhlakazwa okufanayo ye-SiC nanoparticles, ngaleyo ndlela ithuthukise kakhulu amandla kanye ubulukhuni bamathuluzi kanye nokwelula impilo yabo yesevisi.

Ngaphezu kokwakhiwa kwamathuluzi edayimane asekelwe ku-resin,i-silicon carbide nanoparticlesingasetshenziswa futhi ekukhiqizeni ama-abrasives ahlukahlukene kanye namathuluzi okucubungula, njengamasondo okugaya, i-sandpaper, izinto zokupholisha, njll. Ithemba lokufaka isicelo se-nano silicon carbide libanzi kakhulu. Ngokuthambekela okwandayo kwezimboni ezahlukahlukene zokusebenzisa ukusebenza okuphezulu kanye namathuluzi wokucubungula wekhwalithi ephezulu nama-abrasives, i-nano silicon carbide ngokuqinisekile izokhiqiza ukusetshenziswa okubanzi kakhulu kule mikhakha.

Sengiphetha, i-nano silicon carbide powder inethuba elibanzi lokufaka isicelo njengento ephezulu yokupholisha. Ngokuqhubeka okuqhubekayo kwesayensi nobuchwepheshe, i-nano silicon carbide namathuluzi edayimane asekelwe ku-resin azothuthukiswa ngokuqhubekayo futhi athuthukiswe abe yizinkambu ezibanzi.

I-Hongwu Nano ingumkhiqizi ochwepheshe wezimpushana zensimbi eziyigugu ze-nano nama-oxides awo, anekhwalithi yomkhiqizo ethembekile nezinzile kanye nenani elihle kakhulu. I-Hongwu Nano ihlinzeka nge-SiC nanopowder. Siyakwamukela ukuxhumana nathi ukuze uthole ulwazi olwengeziwe.
