I-Galvaning yinkqubo yokusebenzisa umaleko okhuselayo we-zinc kwintsimbi okanye i-iron ukunqanda ukususwa. Inkqubo isetyenziswa ngokuqhelekileyo kwimveliso yemibhobho, ngakumbi ezo zisetyenziswa kumashishini ahlukeneyo njengokwakha, ioyile kunye negesi, kunye nokunikezelwa kwamanzi.Ukulinganisa imigangatho yemibhobhoKubalulekile ukuqinisekisa ukuba umgangatho kunye nokuqina kwemibhobho ye-galvani. Masingene kwiinkcukacha zemigangatho yemibhobho ye-pumela kwaye zithetha ntoni kumgca we-pumela.
I-pume ye-pumeIMigangatho ihleli ilawulwa nguMbutho waseMelika uVavanya kunye nezixhobo (i-ASTM) yombutho wamazwe. I-ASTM ibeka imigangatho ethile yenkqubo ye-GAGNANIT, ebandakanya ubukhulu becala lomaleko we-galvane, umlinganiso we-coraight, kunye nomgangatho wei-gonanicatedumphezulu. Le migangatho ibaluleke kakhulu ekugcineni ukuthembeka kombhobho we-gava kunye nokuqinisekisa ukusebenza kwalo kwizicelo ezahlukeneyo.
Omnye wemigangatho ephambili yombhobho we-galvaning yi-ASTM A123 / 123m, echaza iimfuno ze-pipes eneemveliso zentsimbi, kubandakanya imibhobho. Lo mgangatho ucacisa ubukhulu obuncinci, ubunamatheko kunye nokugqiba kombhobho we-gavani. Ikwabonelela ngezikhokelo zokuhlolwa kunye nokuvavanywa kweI-Galvaning DoayingsUkuqinisekisa ukuthotyelwa kwemigangatho.
In Imigca ye-pume ye-pume, ukuthotyelwa kwe-ASTM A123 / i-A12MM ibaluleke kakhulu ekuveliseni umbhobho ophakathi ophakathi. Inkqubo ye-Galvaning ngokwesiqhelo ibandakanya amanqanaba aliqela, kubandakanya unyango lomphezulu, i-dip-dip ye-dip ye-dip kunye nokuqhubela phambili. Inqanaba ngalinye kufuneka libambelele kwimigangatho ye-ASTM ukufezekisa ubukhulu obufunekayo kunye nomgangatho.
Ukulungiselela umphezulu kubandakanya ukucoca imibhobho ukuba isuse nayiphi na i-rump, isikali okanye ezinye izinto ezinokuthintela ii-galvaningungqimba ukusuka ekubambeleleni. Eli nyathelo libalulekile ekuqinisekiseni ukubambelela kweI-Gavaniation Coatingkumphezulu wombhobho. Inkqubo ye-DAP ye-DAP ye-DAP ye-DAGAN ibandakanya ukuntywila kwemibhobho ecocekileyo kwindawo yokuhlambela ye-zunzi ye-zunc, enesitofu sentsimbi ukwenza intsimbi yokukhusela.
Emva kwenkqubo yokulinganisa, umbhobho uya kuqhubeka nokwenza iposti, enokubandakanya ukucingela, ukudlulisa okanye ukukhangela ubukhulu bokunamathela kunye nokunamathela. La manyathelo okuqhubela phambili alulekileyo ukuqinisekisa ukuba umbhobho we-gavaniseled uhlangabezana neemfuno zemigangatho ye-ASTM kwaye ilungele ukusetyenziswa kwizicelo ezahlukeneyo.
Ukuthobelai-pume ye-pumeImigangatho ayichazi ukuba umgangatho kunye nokuqina kombhobho, kodwa nayo inegalelo intsebenzo yayo yexesha elide kunye nokunganyangeki. I-Astm-Comment Piperment ye-Gavanited ilungele indawo yangaphandle, enomswakama kunye neemeko zobuthathaka, zenza ukuba zilungele ukusetyenziswa ezifana nokusasazwa kwamanzi, inkxaso yolwakhiwo kunye neenkqubo zokumiswa kwemizi.
Kwisishwankathelo, imigangatho ye-pumela echazwe yi-ASTM idlala indima ebalulekileyo kumgca wemveliso ye-pumela. Ukuthobela lo mgangatho uqinisekisa ukubaumbhobho we-gavaDibanisa iimfuno ezifanelekileyo zobungqingqwa, ukunamathela kunye nomgangatho ngokubanzi. Ngokulandela imigangatho ye-ASTM,abavelisiinokuvelisaUmbhobho ophakathi ophakathiOko kubonelela ngokukhusela i-corosions ebalaseleyo kunye nobomi benkonzo kwizicelo ezahlukeneyo zeshishini nezorhwebo.
