Ngokubanzi, kukho iintlobo ezintathu eziphambili zemathiriyeli yentsimbi kwimakethi yangoku yemibhobho yentsimbi:
1)Idiphu eshushu yentsimbi:
Ngokubhekiselele kumbhobho wentsimbi otshisiweyo otshisiweyo, inkqubo yokugalela idiphu eshushu kulapho inxalenye esele yenziwe, umzekelo ipleyiti, irawundi, isikwere okanye ityhubhu exande ifakwe kwibhafu yezinki. Ukusabela kwenzeka phakathi kwentsimbi kunye ne-zinc ngexesha le nxalenye kwindawo yokuhlamba i-zinc. Ubuninzi be-coating ye-zinc buphenjelelwa liqela lezinto, kubandakanywa ubuso bentsimbi, ixesha lentsimbi efakwe ebhafini, ukubunjwa kwentsimbi kunye nobukhulu bentsimbi kunye nobukhulu. Enye inzuzo yediphu eshushu ye-galvanizing kukuba yonke indawo igqunyelelwe kubandakanya imiphetho, iiwelds, njl.njl. ukuyinika ukhuseleko lokutya okujikelezayo. Imveliso yokugqibela ingasetyenziselwa ngaphandle kuzo zonke iimeko zemozulu ezahlukeneyo. Yeyona ndlela idumileyo yokufaka igalvanizing kwaye isetyenziswa kakhulu kushishino lokwakha.
2)Intsimbi yangaphambili:
Intsimbi yangaphambili evuthisiweyo ibhekisa kwintsimbi eyayifakwe igalvanized ngeli lixa ikwifomathi yamaphepha, ngoko ke phambi kokwenziwa ngakumbi. I-pre-galvanization ikwabizwa ngokuba yi-mill galvanized, ngenxa yokuba i-sheet yentsimbi iqengqeleka nge-zinc etyhidiweyo. Emva kokuba iphepha lithunyelwe ngelitye lokusila ukuze ligalelwe isinyithi liyasikwa libe likhulu kwaye libuyiselwe. Ubunzima obuthile busetyenziswe kwiphepha elipheleleyo, umzekelo, i-pre-galvanized Z275 steel ine-275g nge-square meter ye-zinc coating. Namhlanje iibhobho zentsimbi zangaphambili zisetyenziselwa iintlobo ezininzi zeemveliso ezibandakanya i-conduit, imilebe kunye nemijelo evulekileyo.
3)Intsimbi ye-Electro-galvanized:
Intsimbi ye-Electro-galvanized ibhekisa ekusebenziseni idyasi ye-zinc efakwe kwintsimbi usebenzisa i-electro deposition. Intsimbi ye-Electro-galvanized inenzuzo yokuba ubukhulu bengubo bunokulawulwa ngokuzimeleyo kwiindawo zangaphakathi nangaphandle. Ubukhulu bengubo esetyenziswe nge-electro galvanization buchanekile.
Kubomi bemihla ngemihla, sihlala sifumanisa ukuba abanye abathengi bathanda ngokulula ukwenza isiphithiphithi esikhulu malunga nombhobho wentsimbi owenziwe ngamakhala kwimarike yombhobho. Imibhobho ye-galvanized yimibhobho yensimbi eye yafumana inkqubo ye-galvanization ekhusela intsimbi ekugugeni kunye nokugqwala. Ukuveliswa kwemibhobho ye-galvanized kwenzeka kwiinkqubo ezimbini eziphambili: Okokuqala, imibhobho yentsimbi yenziwa kwizinto eziluhlaza, kwaye ke imibhobho ifakwe kwi-zinc etyhidiweyo. Imveliso egqityiweyo yindibaniselwano yeekhemikhali ezidibeneyo zemibhobho yensimbi kunye ne-zinc coating. Kulo mba, umbhobho wentsimbi ofakwe igalvanized gabalala ubhekisa kumbhobho wentsimbi oditshiweyo ngokungqongqo. Imibhobho yegalvanized iza kwiindidi ezahlukeneyo, ubukhulu kunye nobude. Le mveliso isetyenziselwa imibhobho engaphantsi komhlaba, iinkqubo zemibhobho engaphezulu komhlaba, iinjongo zoshishino, iimvavanyo zenzululwazi kunye njl. Namhlanje, singathanda ukunika ulwazi oluthe kratya malunga nenye into ebizwa ngokuba yi "ipayipi yentsimbi" kwishishini lensimbi. Imibhobho ye-Pre Galvanized yenziwe nge-coil/ishidi eliye ladlula kwinkqubo yokufaka igalvanization. Ukugalela okungaphezulu akufuneki emva kokuba ikhoyili/ishidi lenziwe libe yinxalenye yentsimbi yombhobho. Le mibhobho kunye neetyhubhu zinengqibelelo yolwakhiwo oluphezulu kwaye ziyamelana nendalo eyonakalisayo. Imibhobho yeGP kunye neeTubhu zenziwe ngokwemigangatho ye-ASTM. Imibhobho yentsimbi yangaphambili kunye neetyhubhu zenziwe ukusuka kwi-½" ukuya kwisi-8". Amacandelwana anomngxuma wesikweri kunye namacandelwana anomngxuma oxande nawo ayafumaneka ekugqityweni kwangaphambili kwegalvanized. Le mibhobho isetyenziswa ngokubanzi kwisakhelo sokubiyela kunye nolwakhiwo lwangaphakathi njengomsebenzi wetruss kunye nomsebenzi wegrill.
