Ufa wa alumina wopukutira
Ufa wa alumina ndi wabwino kwambiri popanga aluminiyamu ndi zina zomwe zimafuna kuuma ndi kukana kukanda kapena mitundu ina ya kuwonongeka kwa mankhwala. Ufa wa alumina ndi wabwino kwambiri pazinthu zomwe zimafuna dzimbiri ndi kukana kukanda, komanso pazinthu zomwe zimafuna kutentha kwambiri, monga kugwiritsa ntchito magetsi ndi kutentha.
Magwiridwe antchito a malonda:
Chogulitsachi ndi ufa woyera kapena mchenga wabwino ndipo chimakhala ndi ntchito yabwino yochotsa zinthu zonyansa. Sichisungunuka m'madzi, sichisungunuka mu asidi, yankho la alkali. Kukula kwa tinthu ta protocrystal kumatha kusinthidwa.

Khalidwe la Ufa wa Alumina:
1. Kukana mankhwala
2. Alumina woyera kwambiri, kuchuluka kwa alumina kopitilira 99%
3. Kukana kutentha kwambiri, kutentha kwa ntchito ndi 1600 ℃, mpaka 1800 ℃
4. kukana kutentha ndi kugwedezeka, kokhazikika komanso kovuta kusweka
5. Kuumba pogwiritsa ntchito kuponyera, kumakhala ndi kuchuluka kwakukulu
Ufa wa alumina uli ndi ubwino wa kuyera kwambiri komanso kuchulukana kwambiri, makamaka mu zinthu zadothi, magalasi, mapulasitiki, nsalu, zipangizo zomangira, zopopera, mapepala ndi mankhwala, ndi zina zambiri.
Ubwino wa ufa wa Alumina:
1. Kudzera mu mphero yoyendera mpweya ndi magulu asanu a zigawo, kugawa kwa tirigu kumakhala kochepa, mphamvu yopera ndi yayikulu, mphamvu yopukuta ndi yabwino, mphamvu yopera ndi yapamwamba kwambiri kuposa zinthu zofewa monga silika.
2. Tinthu tating'onoting'ono timaoneka bwino, pamwamba pa chinthu chomwe chikupukutidwa pali kusalala kwambiri, mu njira yomaliza yopukutira bwino, zotsatira za kupera ndi kupukuta zimakhala bwino kuposa ufa woyera wa corundum.
1. Kupukuta pazenera la foni, kuphatikizapo kupukuta komaliza kwa siponji ya foni yam'manja ya safiro, chophimba chagalasi la foni yam'manja. Kungagwiritsidwenso ntchito: miyala yamtengo wapatali yopangira, zircon, galasi lapamwamba, miyala yachilengedwe, jade, agate ndi zina zomaliza kugwedezeka (kupukuta makina, kupukuta mpukutu), kupukuta pamanja (kupukuta ndi kupukuta) ndi zina zotero.
2. Kupukuta zitsulo, kuphatikizapo chipolopolo cha foni yam'manja, mawilo agalimoto, kupukuta komaliza kwa zida zapamwamba.
3. Amagwiritsidwa ntchito kwambiri popera ndi kupukuta ma semiconductors, makhiristo, aluminiyamu, chitsulo, chitsulo chosapanga dzimbiri, miyala, galasi, ndi zina zotero.
4. Makamaka yoyenera kupukutira ndi kupukuta zitsulo zosapanga dzimbiri, mkuwa, zipangizo zina zachitsulo, ndi mafakitale agalasi pogwiritsa ntchito galasi.
Kufufuza Kwanu
Ngati muli ndi mafunso aliwonse. Chonde musazengereze kulankhulana nafe.
