Isicelo seNanotitanium dioxide anatase

1. I-Nano titanium dioxide anatase inomsebenzi wokulwa namagciwane ngezinto zayo ze-photocatalytic ezingabhubhisa amagciwane noma zicindezele ukuzala kwawo.I-TiO2 futhi inomsebenzi wokuthuthukisa izakhiwo zemishini ngokuqiniswa kwezinhlayiyana zokuhlakazeka.2. Ezinye zezakhiwo ze-photocatalytic zama-nanomaterials zingathuthukiswa zibe i-nanometer photocatalytic coating.Ekuhloleni kwethu, sisebenzisa i-HWNANO TiO2 titanium dioxide anatase ngemva kokwelashwa okukhethekile kwendawo, exutshwa ne-acrylic resin ehlanzekile, futhi ukuhlolwa kweyunithi efanelekile kwabonisa ukuthi inokonakala okusobala okubangela i-nitrogen oxides, amafutha kanye ne-formaldehyde.Ukuwohloka kwe-nitrogen oxide ukusebenza kahle kungafinyelela ku-80%.3. I-Titanium dioxide inesakhiwo sesigaba se-crystal esihlukene: uhlobo lwe-Anatase (Anatase), uhlobo lwe-Brookite no-Rutile (Rutile).I-Anatase titanium dioxide inekhono eliphezulu le-photocatalytic oxidation, ububanzi bebhendi bayo obunqatshelwe njengeSib = 3.2 eV, obulingana nobude begagasi obungu-387 NRN wamandla okukhanya, isendaweni ye-ultraviolet, ngakho-ke ku-TiO2 photocatalytic oxidation reaction idinga umthombo wokukhanya we-uv, onjalo. njengokukhanya kwelanga, i-halogen tungsten dean, ukukhanya kwesibani se-mercury.Ngaphansi kokukhanya kwe-ultraviolet ibhande layo le-valence eline-electron likhishelwa ebhendini yokuqhuba, futhi ebhandeni le-valence likhiqiza izimbobo.inqubo iwukuthi ngaphansi kwe-uv irradiation, i-TiO2 ikhiqiza i-electron yamahhala, Benza umoya-mpilo emoyeni usebenze futhi ukhiqize umoya-mpilo osebenzayo nama-radicals mahhala.4. Izinhlobo ze-oxygen esebenzayo kanye nama-OH radicals ane-reactivity ephezulu, lapho ukungcola kwe-adsorption phezulu, kuzohlangana nama-electron amahhala kanye ne-The produce redox reaction.Ukuze kuzuzwe inhloso yokuqeda ukungcola.Ukuze uthole ulwazi olwengeziwe lwe-nano TiO2 powder, sicela usithinte ngokukhululekile.

Iphakheji yethu inamandla kakhulu futhi ihlukahlukene ngokwemikhiqizo ehlukene, ungadinga iphakheji efanayo ngaphambi kokuthunyelwa.

lAmanani Anengqondo

lIzinto ze-nano zekhwalithi ephezulu nezinzile

lIphakheji Lomthengi Linikelwe-Izinsizakalo zokupakisha ngokwezifiso ze-oda lenqwaba

lIsevisi Yokuklama Ihlinzekwa-Nikeza ngesevisi ye-nanopowder yangokwezifiso ngaphambi kwe-oda lenqwaba

lUkuthunyelwa okusheshayo ngemva kokukhokha i-oda elincane

Ilabhorethri

Ithimba labacwaningi lihlanganisa abacwaningi be-Ph. D. kanye noSolwazi, abakwazi ukunakekela kahle

we nano powder's ikhwalithi kanye nokusabela okusheshayo kuma-powder ngokwezifiso.

Izisetshenziswazokuhlola nokukhiqiza.

Inqolobane

Izifunda ezihlukene zokugcina ama-nanopowder ngokuya ngezakhiwo zawo.

Umbuzo: Ngingakwazi ukuthola amasampula?

A: Kuncike kusampula ye-nanopowder oyifunayo.Uma isampula likusitoko ngephakeji elincane, ungathola isampula yamahhala ngokukhava nje izindleko zokuthumela, ngaphandle kwama-nanopowder ayigugu, uzodinga ukukhokhela izindleko zesampula nezindleko zokuthumela.

Q: Ngingasithola kanjani isicelo?A:Sizokunikeza isilinganiso sethu sokuncintisana ngemuva kokuthola imininingwane ye-nanopowder njengosayizi wezinhlayiyana, ubumsulwa;imininingwane yokuhlakazeka njengesilinganiso, isixazululo, usayizi wezinhlayiyana, ubumsulwa.

Q: Ungakwazi yini ukusiza nge-nanopowder eyenziwe ngomthungo?A:Yebo, singakusiza nge-nanopowder eyenziwe ngomsiki, kodwa sizodinga inani elincane le-oda kanye nesikhathi esiholayo cishe amaviki angu-1-2.

Q: Ungaqinisekisa kanjani ikhwalithi yakho?A:Sinohlelo lokulawula ikhwalithi ye-strick kanye nethimba labacwaningi elizinikele, besigxile kuma-nanopowder kusukela ngo-2002, sazuza udumo ngekhwalithi enhle, siyaqiniseka ukuthi ama-nanopowder ethu azokunikeza umkhawulo ngaphezu kwezimbangi zakho zebhizinisi!

Umbuzo: Ngingakwazi ukuthola ulwazi lwedokhumenti?A: Yebo, i-COA, i-SEM, i-TEM iyatholakala.

Q:Ngingalikhokhela kanjani i-oda lami?A: Sincoma i-Ali trade Assurance, nathi imali yakho ivikele ibhizinisi lakho endaweni ephephile.

Ezinye izindlela zokukhokha esizamukelayo: PayPal, Western Union, Ebhange, L/C.

Q: Kuthiwani ngesikhathi esisheshayo nesokuthumela?A:Isevisi ye-Courier njenge: DHL, Fedex, TNT, EMS.
