UMnu. Xu wase-Tianjin ungumnikazi wefekthri yokucubungula egxile ekukhiqizeni izingcezu zethusi ezihlukahlukene kanye nokucwecwa kwamathini. Muva nje, uMnu. Xu uthole ukuthi ikhono lokuhlakazeka lesisombululo sokucwenga lalimpofu ngesikhathi senqubo yokukhiqiza. Kodwa-ke, ngokusho kweziphakamiso zomphakeli, okuqukethwe kwe-sulfuric acid kwanda futhi okuqukethwe kwe-stannous sulfate kwakufanelekile. Kodwa-ke, ikhono lokusabalalisa lesisombululo sokucwenga lalisempofu, futhi i-divalent tin esisombululo sokucwenga i-hydrolyzed kalula. Ngenxa yomthelela ongathi sína ekusebenzeni kahle komkhiqizo womsebenzi, uMnu. Xu uhlose ukuwushintsha afake i-acid tin plating brightener enekhono elihle lokuhlakaza.
Ngolunye usuku, uMnu. Xu wabona i-asidi ka-Bigley. i-tin plating brightener Sn-807 ngokusesha ku-inthanethi, ngakho-ke wabuza mayelana nezakhiwo zalesi sikhanyisi futhi wafunda ngokusebenza kwayo kokuhlakazeka. Ngemva kokuqonda isimo sokukhiqiza sikaMnu. Xu, onjiniyela be-Bigley bancome uMnu. Xu ukuba asebenzise lokhu tin plating brightener Sn-807.
Lesi sikhanyiso se-acidic tin plating brightener Sn-807 sakhiwe kusetshenziswa ubuchwepheshe obusha bocwaningo nokuthuthukiswa okuvela I-Bigley nezinto zokusetshenziswa ezingenisiwe. I-Brightener inokugxila okuphezulu kanye nokungcola okumbalwa, iqinisekisa ukuzinza okuhle, ukuhlakazeka, ngisho nokusebenza kokucwenga ngesikhathi senqubo yokukhiqiza. Isixazululo se-plating asithambekele ekubeni ne-turbidity kanye ne-hydrolysis, futhi sihlala sicacile ngemva kokukhiqiza isikhathi eside. Isendlalelo se-tin plating endaweni yokusebenza sinokumelana nokugqwala okuhle kanye ne-solderability. Ngemva kokuqhathanisa izinhlobo ezimbalwa ze- i-acid tin plating brighteners ngesikhathi esisodwa, uMnu. Xu unqume ukuthenga ibhakede le-Sn-807 ukuze azame.
Ngaphansi kokuqondisa okuningiliziwe konjiniyela, uMnu. Xu wasebenzisa lokhu okune-acidic tin Plating additives Sn-807, okuthuthukise kakhulu ukuhlakazeka nokuthengiswa kwe-workpiece coating. Izinga le-workpiece enamathelayo lingahlangabezana ngokugcwele nezidingo zamakhasimende, futhi ukuzinza kwesisombululo sokucwenga kuhle, izinga lokulimala komkhiqizo liphansi, ukukhiqiza kusindisa abasebenzi, futhi izindleko zokukhiqiza zilondolozwa ngo-20%.
Ngakho-ke, ngesikhathi senqubo yokukhiqiza, ikhono lokuhlakaza lesixazululo se-acidic tin Plating limpofu futhi kulula ukulifaka emanzini. Zama i-Bigley's i-acid tin plating brightener Sn-807 ngokushesha ukuze wehlise izinga lokungasebenzi kahle komkhiqizo futhi wonge izindleko zokukhiqiza. Uma unentshisekelo kulokhu kucwebezela kwe-acidic tin plating, sicela uxhumane no-Isevisi yamakhasimende yeBigley ukuze uthole amasampula amahhala kanye nolwazi oluningiliziwe lobuchwepheshe!
