Ziziphi iindlela zokuvelisa i-copper foam?

Igwebu lekopoloyinto entsha esebenza ngeendlela ezininzi. Yenziwa njani? Enyanisweni, njengeninzi yesinyithi Igwebus, i-copper foam isebenzisa kakhulu i-copper njengesiseko sayo. Ngexesha lokuveliswa, ii-pores ezininzi ezidibeneyo okanye ezingadibaniyo zisasazwa ngokulinganayo kuyo yonke i-substrate ye-copper.

I-copper foam ayigcini nje ngokuba neenzuzo zeentsimbi ze-foam kodwa ikwazuza neempawu ze-copper. Umzekelo, ibonisa ukuhanjiswa kombane okugqwesileyo kunye nokuguquguquka. igwebu le-nickel, i-copper foam inika iindleko eziphantsi zemveliso kunye namathuba amaninzi okusetyenziswa. Nangona kunjalo, ngenxa yeempawu ze-copper, zombini i-copper foam kunye ne-copper zabelana ngesiphene sokungamelani kakuhle nokugqwala. Ngezantsi, sichaza iinkqubo zemveliso kunye neendlela ze-foam copper:

1. Umgubo Indlela yeMetallurgy
Le ndlela ibandakanya ukongeza rhoqo izinto ezikhupha amagwebu kwi-copper engumgubo. Xa i-sprinkle igqityiwe, izinto ezikhupha amagwebu ziyaguquguquka, zishiye iimbobo zenze i-copper foam.

2. Indlela yokubeka i-Electrochemical
Ubhedu olunefoam oluveliswa ngale nkqubo lunemilo efanayo kunye nemingxunya emalunga ne-95%, nto leyo eyenza ukuba lufaneleke ngokubanzi kwimveliso yesinyithi esinefoam.

3. Inkqubo yokucocwa nokucocwa kwamanzi
Xa kuthelekiswa neendlela ezimbini zangaphambili, le ndlela iyinkimbinkimbi kakhulu. Okokuqala, kuxutywa umgubo we-electrolytic copper, i-sodium chloride granules, kunye nezinye izongezo ezahlukeneyo. Emva koko umxube ucinezelwa ube yi-compact eluhlaza. Le compact eluhlaza itshiswa kwindawo eshushu ye-argon, kwaye imveliso iyanyibilika kwindawo yokuhlambela yamanzi ashushu ajikelezayo. Emva kokunyibilika, izinto ziyacocwa nge-ultrasonic bath kunye nokuhlanjwa nge-acetone. Emva kokuhlanjwa, zomiswa ukuze zenze isakhiwo esivulekileyo. Nangona kunjalo, le ndlela ivelisa umlinganiselo we-porosity we-50-81% kuphela, kunye nobukhulu be-pore obuphakathi ukusuka kwi-0.2 ukuya kwi-4 mm.

Okwangoku, uninzi igwebu lekopolo Imveliso isebenzisa ikakhulu ezi ndlela zintathu zingasentla. Ukunyibilika komgubo kunye nokufakwa kwe-electrochemical zezona ndlela zisetyenziswa kakhulu kwinkqubo yokuvelisa. Nangona iintsimbi zefoam zineengenelo ezininzi kunye nokusebenza kwazo, kunye namathuba okusetyenziswa ngokubanzi kunye namasimi, ukunciphisa iindleko zemveliso kunye nokuphucula iinkqubo zokuvelisa kuye kwaba yimingeni yesayensi efuna isisombululo.
