UMnu. Zhao wase-Dongguan ungumnikazi wefekthri yokucwenga i-electroplating egxile ekuthinini izixhumi zamabha ethusi ahlukahlukene. Njengoba uMnu. Zhao asebenzisa izithasiselo zokucwenga ze-matte tin, indawo yokugeza yayinegwebu eliningi, futhi ukugeza kwakulula nokuba nemfucumfucu. Umphakeli uncome ukusebenzisa i-ejenti yokwelapha ithini. Ukugeza kungaba ngcono, kodwa izindleko zokukhiqiza zanda kakhulu. Ngakho-ke uMnu. Zhao wayefuna ukuthola ukusebenza okuzinzile, isixazululo se-plating akulula ukuthi sibe nemfucumfucu hanging matte tin plating additives.
Ngolunye usuku, uMnu. Zhao wabona i-Sn-818, isithasiselo sethayela elilengayo. i-plating evela ku-Bigley, ngesikhathi sokusesha ku-inthanethi, futhi yabuza ngezici zayo, umthamo, kanye nokuthi isixazululo sokucwenga sizoba nesiphithiphithi kalula yini ngesikhathi sokusetshenziswa. Ngemva kokuqonda isimo sokukhiqiza sikaMnu. Zhao ngokuningiliziwe, onjiniyela bakaBigley bachazela uMnu. Zhao ukuthi lesi sithako sethayela lesifutho siwumkhiqizo omusha owenziwe ngokuzimela ngu-Bigley, onomklamo ophansi wokubunjwa kwegwebu, futhi wakhiwe kusetshenziswa izinto zokusetshenziswa ezivela kwamanye amazwe. Isixazululo se-plating esihlanganisiwe sinokuzinza okuhle, futhi singakwazi ukugcina ukucaca kwesisombululo se-plating ngesikhathi sokukhiqiza isikhathi eside, ukunciphisa kakhulu izindleko zokwelashwa kwesisombululo sokucwenga. Ngemva kokuqhathanisa imikhiqizo eminingana yohlobo olufanayo ku-inthanethi, uMnu. Zhao unqume ukuthenga kuqala ibhakede lika-Bigley's matte tin plating additives Sn-818.
Mnu. U-Zhao uvule ithangi elisha lokufaka amalitha ayi-100 emugqeni wokukhiqiza futhi wasebenzisa isithasiselo senkungu kathayela ngaphansi kokuqondisa kukanjiniyela. Uthole ukuthi kwakukhona igwebu elincane esixazululweni sokucwenga, iziphanyeko ngeke zisanamathela kugwebu ngesikhathi sokukhiqiza, futhi imvamisa yokushintshwa kwamanzi okuhlanza yancishiswa. Manje kudingekile kuphela ukushintsha amanzi kanye ngosuku. Ngaphambilini, ikhambi lokucwenga laba nesiphithiphithi ngemva kwezinsuku ezi-5 zokukhiqiza. Manje, ngemva kokusebenzisa i-Sn-818, ikhambi lokucwenga selikhiqizwa ngokuqhubekayo izinsuku ezingama-20 futhi lisacacile. Ngaphezu kwalokho, akudingeki ukuthi isetshenziswe ne-ejenti yokwelapha ithini, inciphisa kakhulu izindleko zokukhiqiza. Ngakho-ke, uMnu. Zhao waphinda wafaka i-oda futhi wasayina isivumelwano sokubambisana no-Bigley.
Ngakho-ke, ngesikhathi sokukhiqiza ukulengiswa kwe-spray tin plating, isixazululo se-plating sinegwebu eliningi futhi sivame ukuba ne-turbid. Zama i-Bigley's Sn-818, isithasiselo sokulenga i-spray tin plating, ukuze wehlise ngempumelelo izindleko zokukhiqiza. Uma unentshisekelo kulokhu matte tin plating additives, sicela uxhumane no-Bigley isevisi yamakhasimende ukuze uthole amasampula amahhala kanye nolwazi oluningiliziwe lwezobuchwepheshe!
