Kusukela elabhorethri kuya emgqeni wokukhiqiza, i-palladium (II) monohydrate (PdO · H₂O) iyisihluthulelo esixhumanisa “izinto zokusetshenziswa ze-palladium” “nemikhiqizo esebenzayo enenani eliphezulu” – enikeza izixazululo eziphumelelayo zemikhakha ye-catalysis, i-electronics, kanye ne-jewelking yensimbi eyigugu nge-reactivity yayo elawulekayo kanye nokusebenza kahle kokukhululwa kwe-Pd²⁺ okuzinzile.

【Izinzuzo ezintathu eziyinhloko, ezivumelana nezidingo zezimo eziningi 】

1. I-catalytic precursor esebenza kahle kakhulu: Yenza ukusabela kube okunembe kakhudlwana, izindleko zilawuleke kakhudlwana, futhi umsebenzi ulawuleke: Ingancishiswa kalula ibe yi-nanoscale metal Pd (0 valence), futhi ingasetshenziswa ngqo ukulungiselela ama-catalyst asekelwayo njenge-Pd/C kanye ne-Pd/Al₂O₃, afaneleka ezimweni ezifana ne-"olefin hydrogenation" kuma-petrochemicals kanye ne-"Suzuki cross-coupling" ekuhlanganisweni kwemithi, ngokukhetha kwe-catalytic okuthuthukisiwe ngaphezu kuka-15%. Ukuguqulwa okulula: Isabela nama-organic acids ukuze yakhe ama-catalyst afanayo njenge-palladium acetate, isuse izinyathelo zokuhlanza eziyinkimbinkimbi futhi ihlinzeke ngoshintsho olusheshayo kusuka ekuhlolweni okuncane kwelebhu kuya ekukhiqizweni okukhulu kwezimboni. Ikhwalithi ezinzile: Ubumsulwa obuphezulu (99.95%+) buqinisekisa ukusebenza kahle kwe-catalytic okuqhubekayo, bugwema ukungcola okuphazamisa ukusabela, futhi bunciphisa izinga lokukhubazeka kwemikhiqizo engezansi.

2. Ukukhetha okusha kokufaka i-Electroplating ngokunemba: Shintsha igolide, ukusebenza kwayo kungashintshi, ukuhambisana kwesisombululo okuqinile: Isabela namanzi e-ammonia ukuze yakhe i-tetraamine palladium complex encibilikayo, idale "isixazululo se-palladium plating esisekelwe ku-ammonia", esinokufana kwe-coating okungaphezu kuka-98%, okuhlanganisa izingxenye zokunemba njengezixhumi ze-elekthronikhi kanye nohlaka lwe-IC lead. Inzuzo yokusebenza kwezindleko: Ukuqhuba kukagesi kanye nokumelana nokugqwala kwe-coating kuseduze nokwegolide, futhi izindleko ziyingxenye eyodwa kwezintathu kuphela ze-coating yegolide, okusiza abakhiqizi be-elekthronikhi ukunciphisa izindleko nokwandisa ukusebenza kahle. Inobungani nemvelo: Akukho-cyanide ehilelekile, ngokuhambisana nezindinganiso zokuvikela imvelo ze-RoHS, futhi ifanele izidingo zokukhiqiza eziluhlaza zemikhiqizo ye-elekthronikhi ephezulu.

3. Ithuluzi elinamandla lokubuyisa insimbi eyigugu: Ukwenza ukuvuselela izinsiza ze-palladium kube ngcono kakhulu. Ukuhlukanisa okukhethiwe: Ngokuncika ezicini ze-amphoteric kanye nokuxhumanisa, i-Pd²⁺ ibanjwa ngokunembile ohlelweni lwamanzi lwe-hydrochloric acid/ammonia, ifinyelela ukwahlukana okuphumelelayo kwezinsimbi ezifana ne-platinum, i-rhodium, kanye nethusi, ngesilinganiso sokubuyisa i-palladium esifinyelela ku-99%. Ukwenziwa lula kwenqubo: Ngaphandle kwesidingo semishini eyinkimbinkimbi, i-palladium ingacebiswa ngokushesha kusuka kuma-catalyst emfucuza kanye namabhodi wesekethe yemfucuza, iguqulwe ibe yi-PdO ehlanzekile kakhulu · H₂O noma i-Pd yensimbi, okusiza amabhizinisi ukufeza imigomo emibili "yokuvuselela izinsiza + ukonga izindleko". Ukuhlanza kungalawuleka: Imikhiqizo evuselelwe ingabaKwenziwe ngokwezifiso ngobumsulwa obungu-99.9% kuya ku-99.99%, kufanelekile ezimweni ezahlukene ezingezansi komfula (njenge-palladium powder ye-electronic-grade, usawoti we-palladium we-catalytic-grade).

4. Ukusekelwa okusha kwezinto ze-elekthronikhi: Ukunika amandla izingxenye eziqondile. Izingxenye eziyinhloko ze-conductive paste: Ngemva kokubola kokushisa, kwakheka ifilimu ye-Pd ezinzile, enamathela ngokuqinile ezisekelweni ze-ceramic. Ama-electrode esekethe yefilimu ewugqinsi enziwe anephutha lokuzinza kokumelana elingaphansi kuka-2%, ahlangabezana nezidingo ze-elekthronikhi yezimoto namabhodi okulawula ezimboni. Izinto zokusetshenziswa zesendlalelo esibucayi senzwa: Izinhlayiya ze-nano-PD ezitholakala ngokunciphisa zizwela kakhulu impendulo ye-hydrogen ne-methane yokumuncwa, okwenza kube lula ucwaningo nentuthuko kanye nokukhiqizwa kwezinzwa zegesi ezinembayo ephezulu (njengezixwayiso zokuvuza kwe-hydrogen).
