Kugwiritsa Ntchito Bwino Kwambiri kwa White Corundum Micropowder Popaka Miyala
Kunena zoona, pankhani ya “kupukuta miyala,” lingaliro loyamba la anthu ambiri lingakhale makina akuluakulu, mafakitale okhala ndi phokoso, ndi ma disc opera omwe ali m'manja mwa opukuta odziwa bwino ntchito. Koma ngati mukumvetsa bwino makampaniwa, mudzapeza kuti nthawi zambiri ndi ufa wochepa womwe umatsimikizira zotsatira zomaliza. Mwachitsanzo,ufa woyera wa corundum micropowderTikukambirana lero kuti "katswiri wa kupukuta" uyu wobisika kuseri kwa zochitika. Pamene ndinayamba kugwira ntchito m'munda umenewu, ndinadabwanso: Kodi si kupukuta miyala yokha? "Ufa" uliwonse suli wofunika. Koma nditawona zambiri, ndinazindikira kuti kusankha ufa wochepa woyenera kungapangitse kusiyana kwakukulu mu zotsatira zake.
1. Kodi ufa wa white corundum micropowder ndi chiyani? N’chifukwa chiyani ndi woyenera kupukutidwa?
White corundum, mwachidule, ndi yoyera kwambiri yopangidwa ndi munthuokusayidi wa aluminiyamu (Al₂O₃). Ndi yolimba kuposa corundum yachilengedwe, yokhala ndi kuuma kwa Mohs kwa 9.0, yachiwiri pambuyo pa diamondi ndi silicon carbide. Monga momwe dzinalo likusonyezera, "micropowder" imatanthauza zinthu zomwe zaphwanyidwa ndikusefedwa kukhala ufa wosalala wa micron. Mungafunse kuti: "Kodi chinthuchi sichidzakanda mwalawo?" Izi zikutibweretsera zabwino zake: kuuma kwakukulu koma kulimba kwambiri: tinthu tating'onoting'ono ta corundum toyera sitingathe kusweka, kusunga mphamvu yodula yofanana panthawi yopukuta; kukhazikika kwa mankhwala: sizigwirizana ndi mchere womwe uli mumwala, zomwe sizimayambitsa kusintha kwa mtundu kapena dzimbiri; komanso kukula kwa tinthu tomwe timawongolera kwambiri: zimapereka ntchito yonse kuyambira kupukuta kosalala mpaka kupukuta bwino, zomwe zimapangitsa kuti zikhale zoyenera kwambiri popukuta magawo ambiri. Makhalidwe amenewa amawapangitsa kukhala oyenera kwambiri pokonza miyala yokongoletsera yodziwika bwino monga marble, granite, ndi miyala yopangira.
II. N’chiyani kwenikweni chomwe chimapangitsa kuti ikhale “yogwira ntchito bwino” popukuta kwenikweni?
Anthu ambiri amaganiza kuti kupukuta ndi kungopangitsa kuti pamwamba pa mwala pakhale powala, koma sizili choncho. Njira yabwino yopukuta iyenera kuchotsa mikwingwirima mwachangu pamene pang'onopang'ono ikukongoletsa kuwala, komanso kupewa kupukuta kwambiri kapena kuwononga njere.
1. Kupukuta kosalala, kwapakatikati, komanso kosalala, komalizidwa bwino
Mwachitsanzo, pogwira ntchito ndi pansi pa miyala ya marble:
Kupukuta kosalala (80#-200#): Gwiritsani ntchito choponderaufa woyera wa corundum(monga W40-W20) kuti isalaze bwino pamwamba ndikuchotsa mikwingwirima yozama;
Kupukuta kwapakati (400#-800#): Sinthani ku ufa wosalala (monga W14-W7) kuti mupukute koyamba;
Kupukuta bwino (1500#-3000#): Ngakhale ufa wokhala ndi W3.5 kapena kuchepera ungagwiritsidwe ntchito kuti ukhale wofanana ndi galasi.
Mudzapeza kuti ufa wa zinthu zomwezo, m'makulidwe osiyanasiyana a tinthu, ungagwiritsidwe ntchito nthawi yonse yopukuta, kuchotsa kufunikira kosintha zinthu pafupipafupi—kusunga nthawi, khama, ndi zolakwika.
2. Kumamatira mwamphamvu komanso kupukuta mwachangu
Poyerekeza ndi zinthu zachikhalidwe monga diatomaceous earth ndi cerium oxide, ufa woyera wa corundum, wokhala ndi tinthu tating'onoting'ono tokhala ndi ngodya zakuthwa (m'malo mozungulira), umalowa mosavuta pamwamba pa miyala, zomwe zimapangitsa kuti kudula kukhale kogwira mtima kwambiri. Tayerekeza: kupukuta granite yomweyo ndi ufa woyera wa corundum micropowder kungapangitse kuwala kofanana mu 1/3 nthawi yochepa kuposa kupukuta ndi zinthu wamba.
3. Osasankha zinthu za miyala, amagwiritsa ntchito zinthu zosiyanasiyana
White corundumIli ndi malo ambiri, kaya ndi miyala ya marble yokhala ndi asidi wambiri kapena granite yokhala ndi silika wambiri. Izi ndi zoona makamaka pa miyala yosakanikirana yopangira (monga quartz), yomwe ili ndi utomoni ndi zinthu zamchere. Zinthu zambiri zochotsera utoto wachikhalidwe zimatha kuipangitsa kukhala yopanda utoto kapena yamdima, pomwe corundum yoyera nthawi zonse imapereka kuwala.
4. Kutalika kwa moyo komanso mtengo wotsika
Ngakhale ufa woyera wa corundum micropowder ukhoza kukhala wokwera mtengo pang'ono pa unit iliyonse kuposa zipangizo zina zachikhalidwe, suwonongeka, suuma, ndipo umagwiritsidwanso ntchito mosavuta. Nthawi zambiri, gulu la zinthuzo limatha kuphimba malo ochulukirapo ndi 20%-30%, zomwe zimapangitsa kuti likhale lotsika mtengo kwambiri pakapita nthawi.
Ⅲ. Kodi pali zitsanzo zenizeni? Kodi ndi zothandizadi?
Ndipatseni chitsanzo changa: Chaka chatha, hotelo yolandirira alendo inakonzedwanso. Pansi pa miyala ya beige inali yodzaza ndi mikwingwirima chifukwa cha zaka zambiri zogwiritsidwa ntchito ndipo inali ndi mulingo wowala wosakwana 30. Poyamba gulu lomanga linagwiritsa ntchito ufa wamba wopukuta, koma pambuyo pa mikwingwirima itatu, zotsatira zake sizinali zabwino. Kenako anasintha n’kuyamba kupukuta pogwiritsa ntchito ufa woyera wa corundum micropowder. Pambuyo pa mikwingwirima iwiri yokha, anafika pa mulingo wowala woposa madigiri 75. Mulingo womaliza wa kuwala atangoperekedwa unali pafupi ndi 85. Kasitomalayo nthawi yomweyo anakonzanso panganolo. Katswiri waluso ananena mawu ochokera pansi pamtima kuti: “Chinthuchi chili ngati kupeza chida chatsopano pamasewera—chimapha zilombo mwachangu ndipo sichikuwonongerani thanzi.”
IV. Zochitika Zachitukuko Zamtsogolo? Kodi Zidzasinthidwa?
Pakadali pano, ufa woyera wa corundum umasunga malo olimba pakupukuta miyala, koma ukusinthanso:
Kukula kwa tinthu tating'onoting'ono komanso tochepa: Ufa wa corundum woyera wa Nano-grade (monga W1.0 ndi pansi pake) wayamba kugwiritsidwa ntchito popukuta magalasi, makamaka pokongoletsa mwaluso komanso pokonza miyala mwaluso;
Kugwiritsa ntchito pamodzi: Mwachitsanzo, ikasakanizidwa ndi cerium oxide ndi ufa wa diamondi, imakhala ndi mphamvu yodulira bwino komanso yonyezimira, yoyenera kugwiritsa ntchito miyala yapadera;
Kuteteza chilengedwe ndi chitetezo: Mbadwo watsopano wa matope opukutira pogwiritsa ntchito madzi ukulowa m'malo mwa ufa wakale wouma pang'onopang'ono, kuchepetsa kuipitsidwa kwa fumbi ndikupangitsa kuti zikhale zoyenera kwambiri pamakina odzipangira okha;
Mapeto: Zipangizo Zing'onozing'ono, Mphamvu Yaikulu
Kawirikawiri, timayang'ana kwambiri pa zinthu zoonekeratu—monga mtundu wa makina opukutira kapena mbiri ya gulu lomanga—koma timanyalanyaza tsatanetsatane womwe umakhudzadi zotsatira zake.Ufa woyera wa corundum ndi chinthu "chosavuta, koma chofunikira kwambiri". Ngati mukukonzanso nyumba yanu kapena kugwira ntchito yosamalira miyala, nthawi ina mukadzagwira ntchito yopukuta, mungafunsenso funso lina: "Kodi tikugwiritsa ntchito ufa wotani wa micro powder?" Zotsatira zake zitha kukhala zosiyana kwambiri chifukwa cha funsoli.
