Kenyelletso e qaqhileng
Wasum Dioxide, eo hape e tsejoang ka hore ke Ceria kapa Wasium (IV) oxide, ke motsoako o sa kopaneleng ka lebese le lik'hemik'hale CEO2. Mona ke lintlha tsa bohlokoa tse mabapi le Wasium dioxide:
LITLHAKISO:
Ponahalo:Ke kristale e tšoeu e tšoeu e tiileng.
Sebopeho:Sebaka sa cerium dioxide se abela sebopeho se phofo, moo Setei se seng le se seng se pota-potiloeng ke li-oxygen tsa oksijene, e theha lattice ea cubic.
Ntlha e phahameng ea ho qhibiliha: E na le ntlha e qhibilihang e ka bang likhato tse 4,550 Celsius (4,622 degreees Degreres).
Sepotlapo: Wasum dioxide ha e phutholohe ka metsing empa e ka nka khato e matla ea acium ho theha litlolo tsa Cerium.
Kopo
Katse: Wasum Dioxide e sebelisoa haholo joalo ka li-catalyst li ntse li sebetsa indasteri ea indasteri. E hlalosa thepa ea redox 'me e ka nka karolo ho khethollo le phokotsong. Ts'ebetso ea eona e atileng haholo e joalo ka tšusumetso ea lits'ebetso tsa matsela, moo e thusang ho fetola mesifa e kotsi joalo ka carbonide oxide le naetrogen oxdes.
Moetsi oa Ameli oa Poland:Ka lebaka la thata ka thata, chemium dioxide e sebelisoa e le motsoako oa polasetiki, tšepe le semiconductor li hlaha. E tsebahala ka bokhoni ba eona ba ho tlosa likhahla le ho fana ka pheletso e boreleli, e boleng bo holimo.
Lisele tse tiileng tsa oxide:Cerium dioxide e kenyelletsoa ho lisele tse tiileng tsa mafura e le thepa ea elektrode. Ho thusa ho ntlafatsa ts'ebetso le botsitso ba lisele tsa mafura.
UV Absorber:Cerium Dioxide Nanopangcticles li sebelisoa ka tatellano ea khanya ea letsatsi ho sireletsa letlalo hore le behe mahlaseli a kotsi. Ba sebetsa joalo ka UV Arosorbers, ba fetolela matla a abelang hore ba se ke ba chesa.
Polokelo ea oksijene:Wasum Dioxide e na le bokhoni ba ho boloka le ho lokolla oksijene ho latela tikoloho e potileng. Thepa ena e etsa hore e sebetse ho lits'ebetso tse kang oksijene, lisele tsa mafura le lisebelisoa tsa polokelo tsa oksijene.
Wasum dioxide ka kakaretso e nkuoa e sireletsehile ha e tšoaroa ka nepo. Leha ho le joalo, ho bohlokoa ho nka mehato e hlokahalang ha u sebetsa le likaroloana tse ntle kapa lipere ho qoba ho inhalation kapa ho ikopanya le letlalo le mahlo.
