Xa ukhetha phakathi kwe-black zinc plating kunye ne-blackening kwiindawo ezisikrufu, kubalulekile ukuqwalasela izinto ezininzi ezibalulekileyo:
Ubukhulu bokugquma:isikrufu sokugquma izinki ezimnyamangokubanzi ine-coating etyebileyo xa ithelekiswa ne-blackening. Oku kungenxa ye-chemical reaction phakathi kwe-sodium nitrate kwi-160°C malunga ne-160°C kunye nee-athomu ze-carbon, nto leyo ebangela ukwakheka kwe-black iron oxide (Fe3O4) ngexesha le-blackening, nto leyo ekhokelela kwi-coating ebhityileyo.
Iimpendulo kwi-Acid: Ukuntywiliselaizikrufukwi-asidi kunokunika ulwazi malunga nonyango lomphezulu wazo. Ukuba isikrufu esimnyama sibonisa umaleko omhlophe emva kokuba umaleko omnyama ususiwe kwi-asidi kwaye siqhubeka sisabela kwi-asidi, oko kubonisa ukuba iplati ye-zinc emnyama engasebenziyo. Ngaphandle koko, kusenokwenzeka ukuba imnyama.
Uvavanyo lokukrwela: Enye indlela yokwahlula ezi ndlela zonyango kukusebenzisa uvavanyo olulula lokukrwela ngephepha elimhlophe. Ukukrwela umphezulu omnyama kunokubangela ukuba umbala uphele, njengoko ukukrwela kubandakanya ukusabela kweekhemikhali okutshintsha umphezulu. Kwelinye icala, izikrufu ezineplati ye-zinc emnyama ziya kugcina uqweqwe lwazo njengoko izinto ze-zinc zibotshelelwe kumphezulu nge-electroplating.
Izikrufu zethu ziza ngezinto ezahlukeneyo ezifana nentsimbi yekhabhoni, intsimbi engatyiwayo, ubhedu, intsimbi ye-alloy, nokunye. Zisebenza ngendlela enokulungiselelwa ukuze zihambelane neemfuno zakho ezithile. Nge-zinc plating emnyama engangenisi umhlwa, izikrufu zethu zibonelela ngokhuseleko olugqwesileyo ekuwohlokeni kokusingqongileyo kwaye zibonisa ukugqitywa komgangatho ophezulu. Okanye,izikrufu ezimnyamazibonelela ngokumelana okuphezulu kwe-oxidation kunye nokubonakala komphezulu okhanyayo kancinci, okwenza ukuba zilungele ukusetyenziswa ezifuna iindawo ezingakhanyisiyo.
Ngamafutshane, ukuqonda umahluko phakathi kwe-black zinc plating kunye ne-blackening kubalulekile ekukhetheni uhlobo olufanelekileyo lwe-izikrufu ezenziwe ngokwezifisoezilungele iimfuno zesicelo sakho. Khetha kuluhlu lwethu lweizikrufu ezikumgangatho ophezuluezihlangabezana nemigangatho efunekayo yamashishini ahlukeneyo.
