Ukusetyenziswa
Le mveliso yeyona nto iphambili yokwenza i-electroplating engena-cyanide. Xa yenziwe ibe sisisombululo se-electroplating se-copper esingenayo i-cyanide, inokugquma ngokuthe ngqo iileya zobhedu kwizinto ze-sodium-iron ngokunamathela okugqwesileyo. Ingubo inomphezulu ogudileyo kunye nombala okhanyayo ofanelekileyo. Umthamo oqhelekileyo wesisombululo somxholo wama-60% yi-100 ukuya kwi-120 ml ngelitha, kwaye umthamo we-copper sulfate yi-15 ukuya kwi-20 grams ngelitha. Ukongeza, ukuntywilisela iindawo ezigqunyiweyo kwisisombululo se-1% ukuya kwi-2% sale mveliso ukuze kusebenze umphezulu wazo ngaphambi kokuba i-electroplating iphucule ngakumbi isiphumo se-electroplating.
I-Hydroxyethylidene Diphosphonic Acid (HEDP) luhlobo olutsha lwe-electroplating complexing agent engena-chlorine. Isebenza njenge-stabilizer ephambili yomgangatho wamanzi kwiinkqubo zamanzi okupholisa ezijikelezayo kwaye isebenza ekuthinteleni ukugqwala kunye nokuthintela isikali. Yenye yee-organic polyphosphonic acid agents zonyango lwamanzi. Kukho ezinye iimveliso eziveliswa apha ekhaya zolu hlobo, ezifana ne-Amino Trimethylene Phosphonic Acid (ATMP) enefomyula \([CH_2PO(OH)_2]_3N\), i-Ethylene Diamine Tetra Methylene Phosphonic Acid (EDTMP), nezinye.
Ii-organic polyphosphonic acids luludidi lwee-arhente zonyango lwamanzi ezaphuhliswa ngasekupheleni kweminyaka yoo-1960 kwaye zaqatshelwa malunga neminyaka yoo-1970. Ukuvela kwezi arhente kuphucule kakhulu iteknoloji yonyango lwamanzi. Xa kuthelekiswa nee-inorganic polyphosphates, ii-organic polyphosphonic acids zinozinzo oluhle kakhulu lweekhemikhali, ukumelana ne-hydrolysis, ukunyamezelana nobushushu obuphezulu, idosi ephantsi, kunye nokusebenza okudibeneyo kokubola kunye nokusebenza kokuthintela isikali.
Zisebenza njenge-cathodic corrosion inhibitors kunye ne-non-stoichiometric scale inhibitors. Xa zidibene nezinye ii-arhente zonyango lwamanzi, zinika iziphumo ezinqwenelekayo ze-synergistic. Zibonisa amandla abalaseleyo e-chelating kwii-ion ezininzi zesinyithi kuquka i-calcium, i-magnesium, i-copper kunye ne-zinc, kwaye zineziphumo ezilungileyo zokuvala ukusebenza kwiityuwa ezingaphiliyo zezi metals ezifana ne-calcium sulfate (\(CaSO_4\)), i-calcium carbonate (\(CaCO_3\)) kunye ne-magnesium silicate (\(MgSiO_3\)). Ke ngoko, zisetyenziswa kakhulu kubuchwepheshe bonyango lwamanzi.
I-reagent ye-phosphorylation ye-serine kunye ne-pyranose ekhuselweyo.
