【Saddex faa'iido oo Muhiim ah, La qabsan kara Baahiyaha Duruufo Badan】
1. Horudhaca Katalytic-ga ee waxtarka sare leh: Ka dhigista falgallada kuwo sax ah, kharashkoodu aad u badan yahay, iyo dhaqdhaqaaqa la xakameyn karo: Si fudud ayaa loogu dhimi karaa birta nanoscale Pd (0 valence), waxaana si toos ah loogu isticmaali karaa diyaarinta katalyst-yada la taageeray sida Pd/C iyo Pd/Al₂O₃, kuwaas oo ku habboon xaaladaha sida "olefin hydrogenation" ee kiimikada batroolka iyo "Suzuki cross-coupling" ee isku-darka daawada, iyadoo xulashada katalytic-ga ay kor u kacday in ka badan 15%. Beddelka ku habboon: Waxay la falgashaa asiidhyada dabiiciga ah si ay u sameeyaan katalystyo isku mid ah sida palladium acetate, iyadoo meesha ka saaraysa tallaabooyinka nadiifinta ee adag iyo fududeynta kala-guur degdeg ah oo ka yimaada tijaabooyinka yar yar ee shaybaarka ilaa wax soo saarka warshadaha. Tayada deggan: Nadiifnimo sare (99.95%+) waxay hubisaa hufnaanta katalytic-ga ee joogtada ah, waxay ka fogaataa wasakhda faragelinaysa falgalka, waxayna yareysaa heerka cilladaha ee alaabada hoose.
2. Doorasho cusub oo loogu talagalay saxnaanta Electroplating: Beddel dahabka, waxqabadka oo aan la carqaladeyn, iswaafajinta xalka oo xooggan: Waxay la falgashaa biyaha ammonia si ay u sameeyaan isku-dhafka tetraamine palladium ee milmi kara, iyadoo abuureysa "xal dahaadhka palladium ee ku salaysan ammonia", oo leh isku-mid ah dahaarka oo ka badan 98%, oo daboolaya qaybaha saxda ah sida isku-xirayaasha elektaroonigga ah iyo qaababka hogaanka IC. Faa'iidada waxqabadka kharashka: Korantada korantada iyo iska caabbinta daxalka ee dahaarka ayaa u dhow kuwa dahabka, kharashkuna waa saddex meelood meel ka mid ah kan dahaarka dahabka, taasoo ka caawinaysa soosaarayaasha elektaroonigga ah inay yareeyaan kharashyada oo ay kordhiyaan waxtarka. Deegaanka u wanaagsan: Cyanide kuma lug laha, iyadoo la raacayo heerarka ilaalinta deegaanka ee RoHS, waxayna ku habboon tahay shuruudaha wax soo saarka cagaaran ee alaabada elektaroonigga ah ee heerka sare ah.
3. Qalab awood leh oo loogu talagalay soo kabashada biraha qaaliga ah: Ka dhigista dib-u-warshadaynta kheyraadka palladium mid waxtar badan leh. Kala-soocid xulasho leh: Iyada oo ku tiirsan sifooyinka amphoteric iyo isku-dubaridka, Pd²⁺ si sax ah ayaa loogu qabtaa nidaamka biyaha hydrochloric acid/ammonia, iyadoo la gaarayo kala-soocid hufan oo ka timaadda biraha sida platinum, rhodium, iyo naxaasta, iyadoo heerka soo kabashada palladium uu yahay ilaa 99%. Fududeynta habka: Iyadoo aan loo baahnayn qalab adag, palladium si dhakhso ah ayaa looga hodmin karaa kiciyeyaasha qashinka iyo looxyada wareegga qashinka, iyadoo loo beddelayo PdO · H₂O ama birta Pd, taasoo ka caawinaysa shirkadaha inay gaaraan yoolalka laba-geesoodka ah ee "dib-u-warshadaynta kheyraadka + kaydinta kharashka". Nadiifnimada la xakameyn karo: Badeecadaha dib loo warshadeeyay waxaa laguWaxaa loo habeeyay nadiifnimo ah 99.9% ilaa 99.99%, oo ku habboon xaalado hoos u dhac ah oo kala duwan (sida budada palladium-ka heerka elektaroonigga ah, cusbada palladium-ka heerka catalytic-ka ah).
4. Taageero cusub oo loogu talagalay Agabka Elektarooniga ah: Xoojinta qaybaha Saxnaanta. Qaybaha asaasiga ah ee koolada gudbisa: Ka dib burburka kulaylka, filim Pd oo deggan ayaa la sameeyaa, kaas oo leh dhegdheg xooggan oo ku yaal substrate-ka dhoobada. Elektroodhada wareegga filimka ee qaro weyn ee la sameeyay waxay leeyihiin qalad xasillooni iska caabin ah oo ka yar 2%, iyagoo buuxinaya shuruudaha qalabka elektaroonigga baabuurta iyo looxyada xakamaynta warshadaha. Agabka ceeriin ee lakabka xasaasiga ah ee dareemayaasha: Qaybaha nano-PD ee laga helo dhimista ayaa aad ugu nugul jawaabta nuugista ee hydrogen iyo methane, taasoo sahlaysa cilmi-baarista iyo horumarinta iyo soo saarista dareemayaasha gaaska ee saxsan (sida qaylo-dhaanta daadashada hydrogen).
