Qaphela: ngokweemfuno zomsebenzisi we-nano particle inokubonelela ngeemveliso zobukhulu obuhlukeneyo.

Ukusebenza kwemveliso

I-Nano i-iron oxide luhlobo lwezinto ezininzi ezisebenzayo.Xa ubungakanani bamasuntswana e-iron oxide buncinci ukuya kwisikali se-nanometer (1-100nm), inani le-athomu yomphezulu, indawo ethile yendawo kunye namandla angaphezulu kwamasuntswana e-iron oxide onke akhula ngokukhawuleza ngokuncipha kobungakanani bamasuntswana, ngaloo ndlela ebonisa iimpawu ezincinci. isiphumo sobungakanani, isiphumo sobungakanani bequantum, isiphumo somphezulu kunye nesiphumo se-macroscopic quantum tunneling.I-iron oxide ineempawu ezintle ze-optical, iipropathi zemagneti kunye neempawu ze-catalytic.

Ulwalathiso lwesicelo

I-Nano iron oxide yi-catalyst elungileyo enomgangatho omkhulu othile kunye nesiphumo esimangalisayo somphezulu.Ngenxa yobukhulu obuncinci be-nanoparticles, ipesenti yomthamo womhlaba mkhulu, i-bonding state kunye ne-electronic state of the surface yahlukile kwi-interior of particles, kwaye ukulungelelaniswa okungaphelelanga kwee-athomu kumphezulu kukhokelela ekwandeni kwe-athomu. amandla asebenzayo kumphezulu.I-Catalysts ezenziwe nge-nanoparticles zinomsebenzi ophezulu kunye nokukhetha kune-catalysts eziqhelekileyo, kwaye ziphila ixesha elide kwaye zilula ukusebenza.Iipellets ezingenanto ezenziwe nge-nano α-fe2o3 zidada kumphezulu wamanzi amdaka aqulethe izinto eziphilayo, ukuthotywa kwezinto eziphilayo ngokukhanya kwelanga kunokukhawulezisa inkqubo yokucocwa kwamanzi amdaka.Le yindlela esetyenziswa yi-United States, Japan kunye nezinye ukujongana nongcoliseko olubangelwa kukuchitheka kwe-oyile elwandle.I-Nano α- Fe2O3 isetyenziswe ngokuthe ngqo njenge-catalyst ye-oxidation, ukunciphisa kunye nokuhlanganiswa kwepolymer.I-Nano α- Fe2O3 i-catalyst inokunyusa izinga le-pyrolysis ye-petroleum ngamaxesha angama-1-5, kwaye i-propellant eqinile eyenziwe ngayo esetyenziswa njenge-catalyst yokutsha inokunyusa izinga lokutsha ngamaxesha angama-1-10 xa kuthelekiswa ne-propellant eqhelekileyo, enenzuzo kakhulu ukwenziwa kweerokethi ezisebenza kakhulu kunye nemijukujelwa.

Iimeko zokugcina

Le mveliso kufuneka igcinwe kwindawo eyomileyo, epholileyo kunye nokutywinwa kokusingqongileyo, ayikwazi ukubonakaliswa emoyeni, ngaphezu koko kufuneka igweme uxinzelelo olunzima, ngokuhambelana nokuthuthwa kwempahla eqhelekileyo.

Umbuzo: Ngaba ungandenzela i-quote/invoyisi yeproforma?A: Ewe, iqela lethu lokuthengisa linokubonelela ngeengcaphuno ezisemthethweni kuwe.Nangona kunjalo, kufuneka uqale ucacise idilesi yokuhlawula, idilesi yokuthumela, idilesi ye-imeyile, inombolo yefowuni kunye nendlela yokuthumela.Asikwazi ukwenza isicatshulwa esichanekileyo ngaphandle kolu lwazi.

Umbuzo: Uyithumela njani iodolo yam?Ngaba ungathumela "impahla yokuqokelela"?A: Singathumela iodolo yakho nge-Fedex, TNT, DHL, okanye i-EMS kwiakhawunti yakho okanye ukuhlawula kwangaphambili.Sikwathumela "impahla yokuqokelela" kwiakhawunti yakho.Uya kufumana iimpahla ngeentsuku ezi-2-5 ezizayo emva kokuthunyelwa, Kwizinto ezingekho kwisitokhwe, ishedyuli yokuhanjiswa iya kwahluka ngokusekelwe kwinto.Nceda uqhagamshelane neqela lethu lokuthengisa ukuba ubuze ukuba ingaba impahla ikhona.

Umbuzo: Ngaba uyazamkela iiodolo zokuthenga?A: Siyazamkela iiodolo zokuthenga kubathengi abanembali yetyala kuthi, ungafeksa, okanye uthumele i-imeyile yomyalelo wokuthenga kuthi.Nceda uqinisekise ukuba iodolo yokuthenga inazo zombini iiletahedi yenkampani/iziko kunye nesiginitsha egunyazisiweyo kuyo.Kwakhona, kufuneka ucacise umntu oqhagamshelana naye, idilesi yokuthumela, idilesi ye-imeyile, inombolo yefowuni, indlela yokuthumela.

Umbuzo: Ndingayihlawula njani iodolo yam?Umbuzo: Malunga nentlawulo, siyalwamkela utshintshiselwano lwetelegraphic, imanyano yasentshona kunye nePayPal.I-L/C ingaphezulu kwe-50000USD kuphela isivumelwano.Nokuba yeyiphi indlela yokuhlawula oyikhethileyo, nceda usithumele ucingo lwebhanki ngefeksi okanye nge-imeyile emva kokuba ugqibile intlawulo yakho.

Umbuzo: Ngaba zikhona ezinye iindleko?A: Ngaphandle kweendleko zemveliso kunye neendleko zokuthumela, asihlawulisi nayiphi na imali.

Umbuzo: Ngaba ungandenzela imveliso ngokwezifiso?A: Ewe kunjalo.Ukuba kukho i-nanoparticle esingenayo kwisitokisini, ngoko ewe, ngokuqhelekileyo kunokwenzeka ukuba siyivelisele yona.Nangona kunjalo, ihlala ifuna ubuncinci bemiyinge eodolweyo, kwaye malunga neeveki ezi-1-2 zokukhokela.

Q. Okunye.A: Ngokwemiyalelo yonke ethile, siya kuxoxa nomthengi malunga nendlela yokuhlawula efanelekileyo, sisebenzisane ukuze sigqibezele ngcono uthutho kunye neentengiselwano ezinxulumeneyo.
