Kufotokozera kwa Zinc oxide
Zinc oxide ndi kristalo woyera kapena ufa, wa hexagonal crystal system. Zopanda fungo, zopanda poizoni, zopanda mchenga, zabwino kwambiri. Kachulukidwe 5.606g/cm3, refractive index 2.0041,1800℃ sublimation. Mphamvu yopaka utoto ndiyowirikiza kawiri ya lead lead carbonate, ndipo mphamvu yophimbayo ndi theka la carbon dioxide ndi zinc sulfide. Insoluble m'madzi ndi ethanol, sungunuka mu asidi, sodium hydroxide, ammonium chloride, amphoteric oxide. Yellow ikatenthedwa pa kutentha kwakukulu ndi yoyera ikazizira. Mu mpweya wonyowa, umatenga carbon dioxide ndi madzi ndipo pang'onopang'ono umakhala zinki carbonate. Ikhozanso kuchepetsedwa kukhala zinc zitsulo ndi carbon kapena carbon monoxide. Zinc oxide lattice ili ndi zinc owonjezera, mphamvu yoyamba ya ionization ya nthaka ndi yochepa, yosavuta kutaya ma elekitironi, ndipo zinc oxide electron kuyenda ndi yaikulu kuposa kuyenda kwa dzenje, ikhoza kuonedwa ngati N-mtundu wa semiconductor.
Kugwiritsa ntchito mankhwala
Zinc oxide, yomwe imadziwikanso kuti zinc white, ndi ufa woyera woyera wopangidwa ndi tinthu tating'ono ta amorphous kapena singano. Monga zida zopangira mankhwala, zimakhala ndi ntchito zosiyanasiyana, monga mphira, zamagetsi, zokutira ndi mafakitale ena. Ntchito ndi mphamvu Zinc okusayidi angagwiritsidwe ntchito ngati pigment woyera posindikiza ndi utoto, kupanga mapepala, machesi. M'makampani opangira mphira omwe amagwiritsidwa ntchito ngati mphira wachilengedwe, mphira wopangira ndi latex vulcanized yogwira wothandizila, kulimbikitsa wothandizira ndi utoto. Amagwiritsidwanso ntchito mu pigment zinc chrome yellow, zinc acetate, zinc carbonate, zinc chloride ndi zina. Kuphatikiza apo, imagwiritsidwanso ntchito pazinthu zamagetsi zamagetsi zamagetsi, phosphors, etc.
Ntchito ya mankhwala
Zinc Oxide (ZnO) ndi chinthu chogwira ntchito bwino cha inorganic. ZnO nanopowder imasonyeza zinthu zambiri zapadera, monga zosamuka, fulorosenti, piezoelectric, kuyamwa ndi kumwaza mphamvu ya UV. Zinc oxide nanopowder imagwira ntchito modabwitsa mu kuwala, magetsi, maginito, ndi madera ena ovuta.
