I-galvanizing yinkqubo yokufaka i-zinc ekhuselayo kwintsimbi okanye isinyithi ukukhusela ukubola. Inkqubo idla ngokusetyenziswa ekwenzeni imibhobho, ngakumbi leyo isetyenziswa kumashishini ahlukeneyo afana nokwakha, i-oyile negesi, kunye nonikezelo lwamanzi.Imigangatho yokugalela imibhobhozibalulekile ekuqinisekiseni umgangatho kunye nokuqina kwemibhobho eyenziwe ngamathangi. Makhe singene kwiinkcukacha zemigangatho ye-galvanizing yombhobho kunye nokuba zithetha ntoni kumgca wokugaya umbhobho.
Umbhobho wokugalelaimigangatho ibekwe ikakhulu yi-American Society for Testing and Materials (ASTM) umbutho wamazwe ngamazwe. I-ASTM ibeka imigangatho ethile yenkqubo yokufaka igalvanizing, ebandakanya ubukhulu bomaleko wegalvanized, ukunamathela kokugquma, kunye nomgangatho opheleleyo we-galvanized layer.yenziwe igalatiumphezulu. Le migangatho ibaluleke kakhulu ekugcineni ingqibelelo yombhobho we-galvanized kunye nokuqinisekisa ukusebenza kwayo kwiintlobo ezahlukeneyo zezicelo.
Enye yemigangatho ephambili yombhobho we-galvanized yi-ASTM A123 / A123M, echaza iimfuno zokugquma kweentsimbi kwiimveliso zetsimbi, kuquka imibhobho. Lo mgangatho uchaza ubuncinci bokutyeba, ukunamathela kunye nokugqiba kumbhobho wegalvanized. Ikwabonelela ngezikhokelo zokuhlolwa novavanyo lweiingubo ezifakwe igalvanizedukuqinisekisa ukuthotyelwa kwemigangatho.
In imigca yokufaka umbhobho, ukuthotyelwa kwemigangatho ye-ASTM A123 / A123M ibaluleke kakhulu ekuveliseni umbhobho we-galvanized ophezulu. Inkqubo yokwenziwa kwegalvanizing ibandakanya amanqanaba amaninzi, kubandakanywa unyango olungaphezulu, ukugalela idiphu eshushu kunye nokulungiswa emva kokulungiswa. Inqanaba ngalinye kufuneka lihambelane nemigangatho ye-ASTM ukufezekisa ubungakanani obufunekayo bokugquma kunye nomgangatho.
Ukulungiswa komphezulu kubandakanya ukucoca imibhobho ukususa nayiphi na irusi, isikali okanye ezinye izinto ezinokuthi zithinteleukugalelaumaleko wokuncamathela. Eli nyathelo libalulekile ukuqinisekisa ukunamathela ngokufanelekileyo kweukutyabeka ngegalvanizedkumphezulu wombhobho. Inkqubo yokuntywila eshushu iquka ukuntywiliselwa kwemibhobho ecociweyo kwibhafu yezinki etyhidiweyo, ethi ibotshelelwe ngesinyithi kwintsimbi ukuze yenze isambatho esikhuselayo..
Emva kwenkqubo ye-galvanizing, umbhobho uya kungena emva kokulungiswa, okungabandakanya ukucima, ukunyanzeliswa okanye ukujonga ubuninzi be-coating kunye nokubambelela. La manyathelo asemva kokulungiswa abalulekile ekuqinisekiseni ukuba umbhobho wegalvanized uhlangabezana neemfuno zemigangatho ye-ASTM kwaye ulungele ukusetyenziswa kwizicelo ezahlukeneyo.
Ukuthobelaukugalela umbhobhoimigangatho ayiqinisekisi kuphela umgangatho kunye nokuqina kombhobho, kodwa inegalelo ekusebenzeni kwayo kwexesha elide kunye nokumelana nokubola. Umbhobho we-galvanized we-ASTM ohambelana ne-ASTM ufanelekile ngaphandle, ukufuma okuphezulu kunye neendawo ezinobungozi, okwenza kube yinto efanelekileyo kwizicelo ezifana nokuhanjiswa kwamanzi, inkxaso yesakhiwo kunye neenkqubo zemibhobho yezoshishino.
Isishwankathelo, imigangatho ye-galvanizing yombhobho echazwe yi-ASTM International idlala indima ebalulekileyo kumgca wokuvelisa umbhobho. Ukuthotyelwa kwalo mgangatho kuqinisekisa ukubaumbhobho owenziwe igalvanizedihlangabezana neemfuno eziyimfuneko zokwaleka ubukhulu, ukuncamathela kunye nomgangatho jikelele. Ngokulandela imigangatho ye-ASTM,abavelisiinokuvelisaumbhobho okumgangatho ophezulu wegalvanizedobonelela ngokukhuselwa kokugqwesa okuphezulu kunye nobomi benkonzo kwiintlobo ngeentlobo zezicelo zoshishino kunye nezorhwebo.
