Unyango lokunqanda ukubola kweucingo olunomnathainetha zohlulwe ngokubanzi zibe zintlobo ezimbini: enye idiphu kwaye enye ishushu-dip galvanizing. Ukudipha unyango lwe-mesh yocingo yinkqubo yokugquma iplastiki. Unyango lokudipha lwahlulwe lube yidiphu eshushu kunye nediphu ebandayo ngokokuba ubushushu buyimfuneko. Ngokwedatha yoqobo yokudipha, inokohlulwa ibe yidiphu engamanzi kunye nomgubo. Ukusetyenzwa okuhambelanayo kwahlulahlulwe kulwelo lokudipha kunye nenkqubo yokudipha umgubo. Izixhobo zokudipha ezibandayo ngokuqhelekileyo luhlobo lweworkshop. Ukudipha okushushu kuyafuneka ukuba kutshiswe unyaka wonke. Ngokuqhelekileyo iindibano zocweyo ezincinci zisebenzisa idiphu ebandayo kunye nediphu. Inokwahlulwa ibe yimibala emininzi: ingca eluhlaza emnyama eluhlaza, umbala oluhlaza njalo njalo.
Ukusetyenziswa kwe-galvanizing ye-hot-dip kwi-mesh yocingo iphuhliswa ukusuka kwindlela yomnyango wexesha elide lokutshisa. Inembali yeminyaka eyi-140 ukusukela oko iFransi yafaka igalvanizing yediphu eshushu kushishino ngo-1836. Nangona kunjalo, ishishini lokugalela amanzi ashushu lifumene uphuhliso olukhulu ngophuhliso olukhawulezayo lwentsimbi eqengqelekayo eqengqelekayo kule minyaka ingama-30 idlulileyo.
Inkqubo yokuveliswa kwephepha elifakwe igalvanized eshushu-dip ibandakanya: ukulungiswa kwebhodi yoqobo → unyango lwangaphambili → i-hot-dip plating → i-post-plating yonyango → ukuhlolwa kwemveliso egqityiweyo, njl njl. Ngokwesiko, inkqubo ye-galvanizing ye-hot-dip yohlulwe ibe ziindidi ezimbini: i-annealing ngaphandle komgca kunye nokwahlukana komgca we-annealing yangaphambili ngokwe-plating yangaphambili. I-advanteji ye-hot-dip galvanizing ucingo kukuba inexesha elide lokuchasa ukubola, kwaye ukulungelelaniswa nokusingqongileyo bekusoloko kulunyango oludumileyo lokulwa nokubola. I-Hot-dip galvanizing inobomi obude bokuchasana nomlingo, kodwa ubomi obuchasene nomlingo bahlukile kwiindawo ezahlukeneyo:
Umgaqo we-hot-dip galvanizing: coca iindawo zentsimbi, emva koko unyango lwe-solvent, ntywiliselwa kulwelo lwe-zinc emva kokumisa, intsimbi isabela kunye ne-zinc etyhidiweyo ukwenza i-alloyed zinc layer, inkqubo yile: i-degreasing-water washing-pickling- Nceda i-plating-drying-hot dip galvanizing-separation-separation. Ubukhulu bomaleko wengxubevange eshushu-diphu ixhomekeke ikakhulu kumxholo wesilicon kunye nezinye izinto zekhemikhali zentsimbi, indawo enqamlezileyo yentsimbi, uburhabaxa bomphezulu wentsimbi, ubushushu bembiza yezinc, ixesha lokupholisa, isantya sokupholisa, kunye noguquko olubandayo.
