Kodi ntchito zazikulu za white corundum micropowder ndi ziti?
Ufa wa corundum woyerandi chida chofunikira kwambiri komanso chogwira ntchito mosiyanasiyana. Ntchito zake zazikulu zimagawidwa m'magulu angapo:
1. Ntchito Yaikulu: KulondolaKupera ndi Kupukuta
Iyi ndi njira yachikhalidwe komanso yofunikira kwambiri yogwiritsira ntchito ufa woyera wa corundum micropowder. Chifukwa cha kuuma kwake kwakukulu, kukula kwa tinthu tofanana, komanso kukana kusweka bwino, imalola kuti izitha kuwongolera bwino komanso kutha bwino pamwamba.
Kugwira ntchito ndi zitsulo:
Makampani Opanga Nkhungu: Amagwiritsidwa ntchito popukuta nkhungu zolondola kwambiri (monga nkhungu zagalasi, nkhungu zobayira jekeseni, ndi nkhungu zoponyera zinthu), kuchotsa wosanjikiza woyera (wosanjikiza wowonongeka) pambuyo pa EDM machining kuti akwaniritse galasi lomalizidwa.
Ndege ndi Magalimoto: Kupukuta zinthu zofunika kwambiri monga masamba a injini, ma disk a turbine, ndi ma nozzles amafuta kuti zitsimikizire kuti pamwamba pake pali bwino komanso kuti palibe kutopa.
Zipangizo Zachipatala: Zipangizo zopangira opaleshoni, zoyika mafupa (monga mafupa opangidwa), ndi zida za mano, zomwe zimafuna kupangidwa bwino kwambiri komanso kugwirizana ndi ziwalo zina.
Kukonza Mbali Yowoneka:
Amagwiritsidwa ntchito popera ndi kupukuta bwino magalasi kapena magalasi monga magalasi, ma prism, ndi magalasi, powongolera bwino kulondola kwa pamwamba ndikuchepetsa zolakwika pamwamba.
Makampani Opanga Ma Semiconductor ndi Zamagetsi:
Kupanga Ma Wafer: Amagwiritsidwa ntchito pochepetsa kumbuyo ndi kupukuta m'mphepete mwa ma wafer a silicon.
Kupaka Chip: Kumagwiritsidwa ntchito popera zigawo za oxide ndi zitsulo kuti ziphwanyike pamwamba pa chip (ngakhale kuti njira yodziwika bwino ya CMP pakadali pano imagwiritsa ntchito silica ndi cerium oxide slurry, white corundum ikadalipo).
Amagwiritsidwa ntchito popukuta zinthu zamaginito, zinthu zadothi, makhiristo a piezoelectric, ndi zida zina zamagetsi.
Kukonza Zodzikongoletsera:
Amagwiritsidwa ntchito popukuta ndi kukonza zitsulo zamtengo wapatali (golide, siliva, platinamu) ndi miyala yamtengo wapatali, zomwe zimapangitsa kuti zikhale zonyezimira kwambiri.
2. Monga Chodzaza Chogwira Ntchito
Pogwiritsa ntchito kuuma kwake kwakukulu, kukana kuvala, kukana kutentha, komanso kukhazikika kwa mankhwala,ufa woyera wa corundum imawonjezedwa ku zipangizo zosiyanasiyana kuti iwonjezere mphamvu zake.
Zophimba ndi Pansi Zosatha Kutha:
Kuwonjezera pa epoxy resins, polyurethane, ndi zipangizo zina zapansi, imapanga pansi yamafakitale yosawonongeka kwambiri kuti igwiritsidwe ntchito m'nyumba zosungiramo katundu, malo ogwirira ntchito, malo oimika magalimoto, ndi malo ena omwe amalemedwa ndi katundu wolemera komanso kukangana pafupipafupi.
Amagwiritsidwa ntchito ngati chosakaniza mu zophimba zopopera kapena zophimba kuti awonjezere kutopa ndi kukana dzimbiri kwa malo ogwirira ntchito.
Zipangizo Zapamwamba Zopangira Mpweya Wosayatsa:
Monga chowonjezera chofunikira, chimagwiritsidwa ntchito popanga zinthu zotayidwa ndi ladle, zipangizo zachitsulo, zinthu zoumba zopingasa, ndi zina zambiri. Chimawonjezera kwambiri mphamvu, kukana dzimbiri, komanso kukhazikika kwa kutentha kwa zinthu zopingasa.
Zopangira za Ceramic:
Powonjezeredwa ku zoumba zadothi (monga alumina ceramics ndi silicon carbide ceramics) ngati gawo lolimbitsa, zimawonjezera kulimba, kuuma, ndi kukana kuwonongeka kwa zoumba zadothi.
Zida Zopera ndi Kudula:
Kupanga zinthu zomangira zomangira monga mawilo omangira omangira opangidwa ndi utomoni, malamba omangira, sandpaper, ndi miyala yamafuta.
Popanga zida monga mabala a diamondi ndi mawilo opukutira, imawonjezedwa ngati chotsukira chomwe sichimathandiza kwambiri kumutu wodula kuti ithandize kuchotsa tchipisi ndikuwonjezera luso lodula.
Zipangizo Zina Zopangira:
Powonjezeredwa ku pulasitiki ndi rabala, imatha kusintha kutentha, kukana kuwonongeka, komanso kulimba kwa zinthuzo. Mwachitsanzo, imagwiritsidwa ntchito popanga ma brake pads ogwira ntchito kwambiri komanso zipangizo zokankhira.
3. Kuphulitsa Mchenga ndi Kuchiza Pamwamba: Kuphulitsa Mchenga Konyowa:
Ufa woyera wa corundum umasakanizidwa ndi madzi kuti apange matope omwe amagwiritsidwa ntchito poyeretsa pamwamba, kuchotsa zinthu zowononga, komanso kumaliza zinthu zolondola. Poyerekeza ndi kuphulika kwa mchenga wouma, kuphulika kwa mchenga wonyowa kumapereka mphamvu yabwino yowongolera kuuma kwa pamwamba, kumachepetsa fumbi, komanso sikukhudza kwambiri ntchito yogwirira ntchito, zomwe zimaletsa kusinthika.
Kupukuta Mchenga Wouma:
Ngakhale tinthu tating'onoting'ono ta corundum tomwe timakhala tolimba kwambiri timagwiritsidwa ntchito kwambiri, ufa wopangidwa ndi ma micronized ungagwiritsidwenso ntchito pochiza pamwamba pa zinthu zomwe zimafuna zinthu zazing'ono kwambiri, monga kuyeretsa ndi kukonza zinthu zachitsulo zomwe zimakhala zovuta kuzisamalira.
4. Ntchito Zina Zapadera
Mabeya a Zida Zolondola:
Yogwiritsidwa ntchito pakupukuta ndi kumalizamaberiya a miyala yamtengo wapatali (monga maberiya a agate) mu mawotchi apamwamba.
Kafukufuku ndi Kuyesera:
Mu malo ophunzirira za sayansi ya zinthu, kupopera mchenga wonyowa kumagwiritsidwa ntchito pokonzekera zitsanzo za metallographic, zomwe zimavumbula bwino kapangidwe kake ka zinthu zachitsulo kudzera mu kupukuta ndi kupukuta.
Chidule cha Makhalidwe (Chifukwa Chake Amagwiritsidwira Ntchito Kwambiri M'magawo Awa):
Kulimba Kwambiri: Ndi kulimba kwa Mohs kwa 9, kwachiwiri pambuyo pa diamondi ndi silicon carbide, kuphulika kwa mchenga wonyowa kumathandiza kuti zinthu zambiri zigayidwe bwino.
Kukula kwa Tinthu Tofanana: Kulemba bwino kwambiri kumapangitsa kuti tinthu tating'onoting'ono tigawidwe bwino, zomwe zimapangitsa kuti zinthu ziyende bwino komanso mosasinthasintha.
Kukana Kwabwino Kwambiri Kuvala: Kuwonongeka kochepa panthawi yogwiritsa ntchito, zomwe zimapangitsa kuti ntchito ikhale yayitali.
Kukhazikika Kwambiri kwa Mankhwala: Sichichita zinthu pogwiritsa ntchito mankhwala ndi chinthu chogwirira ntchito, zomwe zimapangitsa kuti chikhale choyenera kwambiri popangira zitsulo zosinthika monga chitsulo chosapanga dzimbiri ndi titaniyamu.
Kukana Kutentha Kwambiri: Kusunga magwiridwe antchito abwino kwambiri ngakhale m'malo otentha kwambiri.
Kuyera Kwambiri: Kuchepa kwa kuipitsidwa, kuonetsetsa kuti pamwamba pa ntchito sipaipitsidwa panthawi yopangira.
