Yiziphi izindlela zokukhiqiza i-copper foam?

Igwebu lethusikuyinto entsha esebenza ngezindlela eziningi. Ikhiqizwa kanjani? Eqinisweni, njengeningi lensimbi Igwebus, i-foam yethusi isebenzisa kakhulu ithusi njengesisekelo sayo. Ngesikhathi sokukhiqizwa, izimbobo eziningi ezixhunyiwe noma ezingaxhumene zisakazwa ngokulinganayo kuyo yonke i-substrate yethusi.

I-foam yethusi ayigcini nje ngokuba nezinzuzo zensimbi ye-foam kodwa futhi izuza izimfanelo zayo ezingokwemvelo zethusi. Isibonelo, ibonisa ukuhanjiswa kukagesi okuhle kakhulu kanye nokuguquguquka. Uma kuqhathaniswa igwebu le-nickel, i-foam yethusi inikeza izindleko zokukhiqiza eziphansi kanye nekhono lokusebenzisa elibanzi. Kodwa-ke, njengoba ifa izici zethusi, i-foam yethusi kanye nethusi zihlanganyela ebuthaka bokumelana nokugqwala okubi. Ngezansi, sichaza izinqubo zokukhiqiza kanye nezindlela ze-foam copper:

1. Impuphu Indlela Yokwenza Insimbi
Le ndlela ihilela ukufaka izinto ezikhipha amagwebu ngokuqhubekayo kuthusi oluyimpuphu. Lapho kuqedwa ukusha, izinto ezikhipha amagwebu ziyashintshashintsha, zishiye izimbobo zenze ithusi elinogwebu.

2. Indlela Yokufaka I-Electrochemical
Ithusi elinogwebu elikhiqizwa ngale nqubo libonisa izimo ezifanayo kanye nobukhulu obungaba ngu-95%, okwenza lifaneleke kakhulu ekukhiqizweni kwensimbi enogwebu.

3. Inqubo yokususa amanzi ngokucwilisa
Uma kuqhathaniswa nezindlela ezimbili zangaphambilini, le ndlela iyinkimbinkimbi kakhulu. Okokuqala, kuhlanganiswa i-electrolytic copper powder, i-sodium chloride granules, kanye nezinye izithako ezahlukahlukene. Ingxube ibe isicindezelwa ibe yi-compact eluhlaza. Le compact eluhlaza ishiswa emoyeni we-argon, bese umkhiqizo uncibilikiswa ebhavini lamanzi ashisayo elijikelezayo. Ngemva kokuncibilika, izinto ziyahlanzwa ebhavini le-ultrasonic kanye nokugezwa nge-acetone. Ngemva kokugezwa, komiswa ukuze kwakheke isakhiwo esivulekile. Kodwa-ke, le ndlela iveza isilinganiso se-porosity esingu-50-81% kuphela, kanye nosayizi we-pore omaphakathi osukela ku-0.2 kuya ku-4 mm.

Okwamanje, iningi igwebu lethusi Ukukhiqiza kusebenzisa kakhulu lezi zindlela ezintathu ezingenhla. I-powder metallurgy kanye ne-electrochemical deposition yizindlela ezisetshenziswa kakhulu enqubweni yokukhiqiza. Nakuba izinsimbi ze-foam zinezinzuzo eziningi kanye nokusebenza kahle, ngamathuba amaningi okusetshenziswa kanye namasimu, ukunciphisa izindleko zokukhiqiza kanye nokuthuthukisa izinqubo zokukhiqiza kuye kwaba yizinselele zesayensi ezidinga isixazululo.
