Ubuchwepheshe Bokusungula Nokuhlola Ukusetshenziswa Kwe-Brown Corundum Micropowder
Namuhla, ake sixoxe ngomngane wakudala—i-corundum micropowder ensundu. Le nto ingumlandeli embonini yethu yamathuluzi okukhuhla nokugaya. Sekuyiminyaka, ngenxa yobulukhuni bayo obuphezulu, ukuqina kwayo okumangalisayo, kanye nokusebenza kahle kwezindleko, ibe negalelo elikhulu emikhakheni yendabuko njengensimbi, izinto zobumba, kanye nengilazi.
Kodwa ngiyazibuza ukuthi nonke niyavumelana yini nalo mbono: eminyakeni yamuva nje, ngizizwe ngingakhululekile ukubambelela kula makhono akudala. Imakethe nezidingo ziyashintsha, futhi ubuchwepheshe obudala bufinyelela imikhawulo yabo. Ngakho-ke, namuhla, ngifuna ukuxoxa ngendlela i-brown corundum micropowder, ngokusebenzisa ubuchwepheshe "obuziguqulayo", ekwazile ngayo ukugqashula phakathi kwenqwaba yezinto ezintsha futhi yakha indawo entsha.
Ⅰ. Amahlumela Amasha Avela Esihlahleni Esidala: “Izimpumelelo” Ezintathu Ekusunguleni Ubuchwepheshe
Ungacabangi lokhoi-corundum micropowder ensundu ubuchwepheshe bufinyelele umkhawulo wabo. Amandla abo makhulu kakhulu kunalokho wena noma mina engikucabangayo. Intuthuko yangempela yenzeke ngesikhathi sokuthuthukiswa kwethu okucophelelayo.
1. Inguquko Ekunciphiseni Nokubumba Izinhlayiya
Esikhathini esidlule, lapho sikhuluma ngama-micropowder, kungenzeka ukuthi sasicabanga ukuthi i-D50 yama-micron ambalwa yayivele ihlaba umxhwele. Kodwa manje, umncintiswano wangempela usemazingeni e-submicron ngisho namazinga e-nanometer. Ngobuchwepheshe obuthuthukisiwe bokuchoboza kanye nezinqubo zokuhlukanisa ezinembile, manje sesingakwazi ukukhiqiza ama-powder acwebezelayo anokusatshalaliswa kosayizi wezinhlayiya okufanayo njengokungathi ahlungwe ngesihlungo.
Akusikho konke lokho; sesiqalile ngisho “nokubumba” lezi zinhlayiya ezincane. Uzwile kahle. Izindlela zokuchoboza zendabuko zikhiqiza izinhlayiya ezigobile, ezifana nezingcezu zengilazi ephukile. Manje, ngokusebenzisa amasu okwakha akhethekile, singakhiqiza ama-micropowders e-corundum ansundu anobukhulu obuphezulu kanye nezindawo ezibushelelezi. Ungawuthathi kalula lo “mumo”; “isikhali sokubulala” sangempela ekupholisheni okunembile okuphezulu, kunciphisa kakhulu imihuzuko futhi kufezwe ubuso obubushelelezi kakhulu. Kufana nokusebenzisa i-sandpaper elukhuni ukuze upholishe bese ushintshela ku-deerskin encane. Ingabe umphumela uzoba ofanayo?
2. “Ukumboza” Izinhlayiya: Ukuguqulwa Komphezulu
I-micropowder ye-corundum ensunduiqondile futhi inamandla aphezulu okwakheka, okwenza ithambekele ekuhlanganisweni. Futhi ayihlangani kahle nezinye izinto ze-polymer, njengamafutha namanzi. Yilapho ubuchwepheshe bokuguqula ubuso busiza khona.
Kalula nje, ngezindlela zamakhemikhali noma zomzimba, "ingubo encane" - ama-molecule ambalwa nje obukhulu - ifakwa ebusweni be-micropowder ngayinye. Le ngubo ingaba yi-silane coupling agent, i-titanate, noma enye i-ejenti. Le ngubo inezinzuzo ezisheshayo: Okokuqala, iqeda ukuhlangana, ithuthukise ukuhlakazeka futhi iqinisekise ukusebenza okufanayo. Okwesibili, isebenza "njengomxhumanisi," ithuthukisa kakhulu amandla okubopha phakathi kwe-micropowder kanye ne-substrates njenge-resin nerabha. Lokhu kukhulisa kakhulu amandla nokuqina kwamasondo okugaya aphumayo nama-disc okusika. Lokhu kufana nokupenda kabusha ngopende olwa nokugqwala bese uyifaka kukhonkolo, kudala isibopho esiphephile.
3. Kusukela “eSosheni Elilodwa” Kuya “eNdleleni Ehlanganisiwe”
Ukuzikhandla ngokwakho akusasebenzi; ukusebenzisana kubalulekile. I-brown corundum micropowder nayo ifakiwe ezinhlanganisela. Isibonelo, siyihlanganisa nezinye izinhlayiya ezisebenzayo, njenge-cerium oxide ne-silicon carbide, ngezilinganiso ezithile kanye nezakhiwo ukuze kudalwe izinhlayiya ezihlanganisiwe.
Lokhu kubhula okuhlanganisiwe kungaphezu nje kwe-1+1=2 elula. Kugcina izinzuzo zokuqina kwe-brown corundum ngenkathi kufaka phakathi umsebenzi wamakhemikhali ophezulu we-cerium oxide kanye nokuqina okuphezulu kwe-silicon carbide. Lapho kupholishwa ama-wafer e-semiconductor, ukusebenza kahle kwayo kanye nokusebenza kwayo kudlula kakhulu okokubhula okukodwa. Le ndlela isinika inhlanganisela enamandla yokubhula, iletha ukubhula okunamandla kakhulu.
Ⅱ. Ukuvula Isisekelo Esisha: Izinhlelo Ezintsha Ezizokukhazimulisa
Ngokuthuthuka kwezobuchwepheshe, ububanzi bokusetshenziswa buye banda ngokwemvelo. I-brown corundum micropowder manje isidlule kakhulu ububanzi bokugaya bendabuko futhi iyachuma emikhakheni eminingana yanamuhla.
1. “Ingcweti Yokupholisha Okunembile” Embonini Ye-Semiconductor kanye Ne-Optoelectronics
Lena ingenye yezinkambu ezinenani eliphakeme kakhulu okwamanje. Ubuchwepheshe obuhle kakhulu, obubumbekayo, kanye nokuguqulwa okukhulunywe ngabo ekuqaleni buthole ukusetshenziswa kwabo okuphelele lapha. Isibonelo, enkambisweni yokugcina yokupholisha ye-LED sapphire substrates, ingilazi ebonakalayo, kanye nama-silicon wafers, i-corundum micropowder ensundu ecwebezelayo ehlanzekile kakhulu ivumela ukucubungula okungenamonakalo, okubushelelezi kakhulu, okuhlobene ngqo nokukhiqizwa komkhiqizo kanye nokusebenza. Kuphephile ukusho ukuthi wonke ama-smartphone onawo cishe anengxenye epholishwe ngokunembile ngayo.
2. “Uhlaka Olungabonakali” Lweziphazamiso Ezimbozwe Ngezindwangu Eziphezulu
Indwangu ye-emery yendabuko kanye nephepha lesihlabathi kujwayelekile kuwo wonke umuntu. Kodwa-ke, iziqholo ezimboziwe eziqinile nezimelana nokuguguleka sezidumile manje. Lapha, i-corundum micropowder ensundu eguquliwe ngokukhethekile iboshwe ngokuqinile ngama-resin asebenza kahle kakhulu ukudala amabhande nama-disc okusonga ahlala isikhathi eside kakhulu. Asetshenziselwa ukupholisha ama-blade ezinjini zezimoto kanye nefenisha yokhuni oluqinile olusezingeni eliphezulu, okufeza ukusebenza kahle okuphezulu kanye nekhwalithi ephezulu yobuso, okwenza kube amathuluzi abalulekile okuthuthukisa ukukhiqiza.
3. “Inkanyezi Ekhuphukayo” Yezigcwalisi Zokuqinisa Ezisebenzayo
Ngaphandle kwezinto zokubhula, kuyaqina futhi. Ukwengeza inani elifanele le-corundum micropowder ensundu kwezinye izinto ezikhethekile zobumba noma izinhlanganisela ze-polymer kungathuthukisa kakhulu ubulukhuni bento, ukumelana nokuguguleka, kanye nokuqina kokushisa. Isibonelo, ingasetshenziswa ukukhiqiza amapayipi asebenza kahle kakhulu, angagugi kanye namagiya epulasitiki obunjiniyela akhethekile, okwenza lezi zingxenye ziqine futhi zingagugi.
4. Umlingani “Oqinile” Ekuphrinteni Kwe-3D
Nakuba lokhu kungase kuzwakale kumangaza, i-brown corundum micropowder isiqalile ngisho nokuthola indlela yayo yokungenaUkuphrinta kwe-3DKweminye imikhuba yokusika i-laser (SLS) ekhethiwe, ixutshwa nezinye izimpushana zensimbi noma ze-ceramic. Ngemva kokucutshungulwa okulandelayo, ubulukhuni bomphezulu kanye nokumelana nokuguguleka kwento yokusebenza ephrintiwe kungathuthukiswa kakhulu, kuhlinzekwe indlela entsha yokukhiqiza izingxenye ezingagugi ezinezakhiwo eziyinkimbinkimbi.
Ake sixoxe ngezindaba ezisebenzayo: Izinselele kanye Nombono
Yiqiniso, ikusasa liqhakazile, kodwa indlela ebheke phambili nayo igcwele ukujikajika. Sibhekene nezinselele zangempela: izindleko zokukhiqiza izimpushana ezi-ultrafine ziphezulu, futhi ukulawulwa kwekhwalithi kunzima; ukuqoqwa kwedatha yenqubo ezindaweni ezintsha zokusetshenziswa akwanele; futhi ukuncintisana okuvela “kubadlali abasezingeni eliphezulu” njenge-silicon carbide ne-diamond kudala ingcindezi enkulu.
Kodwa ngikholwa ukuthi isihluthulelo sisekushintsheni kokucabanga kwethu. Impuphu ye-corundum ensundu ayisakwazi ukubhekwa njengento eluhlaza elula, kodwa kunalokho "njengeplatifomu yobuchwepheshe" engathuthukiswa futhi yenziwe ngokwezifiso ngokuqhubekayo. Esikhathini esizayo, noma ngubani ongafinyelela impumelelo ezintweni ezinhle kakhulu, ezihlanzekile, nezisebenzayo, noma ngubani ongaqonda kangcono amaphuzu abuhlungu ezicelo ezingezansi futhi anikeze isethi ephelele yezixazululo, uzothatha isinyathelo kule makethe enamandla.
