Oxide e zinki. Properties le Dikopo

Zinki oxide e (lebitso la e mong - zinki oxide e) - ke e oxide e amphoteric, bonaletsang colorless phofo yellowing holim 'futhumatsang butle-butle' me sublimating likhato 1800. Insoluble ka metsing. The ho kena moea oa zinki ka metsoako e - 2. The lik'hemik'hale moralo ZnO. lintho tse bonahalang Sena ke sa bohlokoa bakeng sa moloko oa batho. Ho e na le phello e litsobotsi li ngata ka 'mele oa motho.

4. Ha alloying le oxides alkali le diforomo oxide e zinki le zincate.
5. Ha alloying le oxide e silicon e le oxide e boron, silicates zinki le mefuta e collars le kang khalase.

Ka oxide e lokiselitsoeng zinki (ZnO)

oxide e zinki ka fumanoa ka litsela tse ngata:

• Natural matsoai zincite;
• ke tukang zinki mouoane (Zn) oksijene (O) - ho thoeng "French thulaganyou e";
• ke li bole kapele 'mogote tsa metsoako latelang: hydroxide Zn (OH) 2, zinki ea acetate Zn (CH3COO) 2 nitrate Zn (NO3), carbonate ZnCO3;
• tlas'a oxidative ZnS a betsa (zinki sulfide);
• ha hydrothermal tswakana;
• ke tse qotsitsoeng ea sludges le dusts smelters. Le ea bohlokoa ho khetheha ba elang limela tse specialize a tšepe sephephechaneng, e nang le karolo e khōlō ea tšepe e galvanized.

oxide e zinki

oxide e zinki le sebelisitsoe ka indasteri rabara, pampiri, ba bang ba dipolasetiki, thepa rabara, letlalo maiketsetso, lik'hebole motlakase, khalase, letsopa, litlolo (tanning kerime, mekhoa ea phekolo e botle) le litlolo tse nkhang hamonate. E sebelisoa e le activator bakeng sa vulcanization ea tse fapa-fapaneng taba rubbers sethothetsi tswakana manyolo - methanol, chloroprene rubbers le moemeli vulcanizing, e pigment le filler tlhahiso ena. Pele oxide e zinki ho ne ho hlokahala ka pigment tšoeu ka pente le enamels, empa hona joale e ka ho feletseng lelekoa TiO2 (thaethaniamo dioxide e ke bao e seng chefo). Atile zinki oxide e le a ka pente, lebili le oli hloekisoa liindasteri le.

Atile le zinki oxide meriana le famasi (lithethefatsi "zinki mafura", "Sudocrem", "ho peista Lassara"). E sebelisoa e le karolo ea setlolo sebolaya dikokwana-hloko, ka mokgwa wa powders. Ikatisetsa e sebelisoa ho bōpa e bactericidal le Roala siling lipetlele, bokaholimo ba ikhopolang ho hloekisa. Ka oxide e zinki hlahiswa lisepa tsa meno le cements bakeng sa ho phekola meno e thibelang. Pele e sebelisoa o pharalletse indasteri bakeng sa tlhoekiso photocatalytic tsa metsi.

Hape ka eona e le ntho e sebelisitsoeng ka eona ka tlhahisong ea pente le khalase e thehiloeng khalase mokelikeli, e le karolo e 'ngoe ea e mafome remover hape e le tseloe ho fepa ka liphoofolo. Ho phaella moo, phofo ea ntho e ke tse bonahalang hlamatsehang ka mahareng sebetsa lasers phofo. Motheong oa oxide e zinki bōptjoa The LEDs mebala e putsoa. Ba bang ba nanostructures (mohlala, a masesaane filimi) e thehiloeng ntho ena ka sebelisoa ka e hlahlobang tsa likokoana-hloko kapa khase-hlokolosi.

ke tshusumetso ka oxide e zinki batho eng?

Sena lobed lik'hemik'hale o tlaase toxicity. Ka moea oa jareteng sebetsa MPC e lokela ho ba ha ho miligram fetang 6 ka mitha dikhubu. Lerōle la oxide e zinki ka thehoa holim 'a betsa lihlahisoa koporo. Ex mosebetsi le oxide e zinki li tlameha ntho ha e kena leihlo. Lithethefatsi le oxide e zinki buelloa feela ka tsamaisoa ke ngaka.
