Iimbonakalo
1.Ukhuseleko oluphindwe kabini lomaleko we-zinc:
I-alloy ye-iron-zinc alloy layer (amandla okuqina okubophayo) kunye nomgangatho ococekileyo we-zinc wenziwa phezu komhlaba, ukwahlula umoya kunye nokufuma, ukulibazisa kakhulu ukubola kwemibhobho yentsimbi.
2.Ukhuseleko lwe-anode yomnikelo:
Nangona i-coating yonakaliswe inxalenye, i-zinc iya kugqwala kuqala (ukukhuselwa kwe-electrochemical), ukukhusela i-substrate yensimbi ekukhukuleni.
3. Ubomi obude:
Kwindawo eqhelekileyo, ubomi benkonzo bunokufikelela kwiminyaka engama-20-30, ede kakhulu kunemibhobho yentsimbi eqhelekileyo (njengobomi bemibhobho epeyintiweyo malunga neminyaka emi-3-5)
Qhagamshelana nathi ngeNgcaciso ezongezelelekileyo kwiMibhobho yeNtsimbi yeGalvanized.
Ishushu-dipumbhobho owenziwe igalvanizeds zisetyenziswa ngokubanzi kwizakhiwo zokwakha (ezifana trusses fektri, scaffolding), ubunjineli kamasipala (guardrails, izibonda ukukhanya esitratweni, imibhobho yamanzi), amandla kunye namandla (iinqaba zothumelo, izibiyeli photovoltaic), izibonelelo zolimo (amathambo greenhouse, iinkqubo zokunkcenkceshela), ukuveliswa kwemizi-mveliso (iishelufa, imigudu yokungena umoya) kunye nezinye iindawo ezigqwesileyo zamandla kunye nokuxhathisa ubomi obude, ukuqina okuphezulu kunye nokuxhathisa ubomi obude. Banikezela ngokhuseleko olungahlawulelwayo, oluphantsi kunye noluthembekileyo kwindawo yangaphandle, enomswakama okanye eyonakalisayo kunye nobomi benkonzo ukuya kuthi ga kwi-20-30 iminyaka. Ziyisisombululo esikhethiweyo sokulwa ne-corrosion ukutshintsha imibhobho yentsimbi eqhelekileyo.
Inkqubo yemveliso yemibhobho edityanisiweyo ejikelezileyo enezinki ilandela la manyathelo:
1. Imathiriyeli ekrwada Pretreatment: Khetha iikhoyili zentsimbi ezinekhabhoni ephantsi, zinqumle zibe yimicu yobubanzi obufanelekileyo, zikhenkciwe ukuze zisuse isikali, zihlanjululwe ngamanzi acocekileyo, zomiswe ukuze zithintele umhlwa.
2. Ukuqulunqa kunye nokuWelding: Iintsimbi zetsimbi zondliwa kwi-roller press kwaye ngokuthe ngcembe zifakwe kwiibhilidi zetyhubhu ezijikelezayo. Umatshini we-welding we-high-frequency welding unyibilikisa i-tube billet seams kwaye uyicinezele kwaye udibanise, wenze ityhubhu ejikelezileyo emnyama. Emva kokupholisa kwamanzi, iityhubhu zilinganisiwe kwaye zilungiswe, kwaye zinqunywe ubude njengoko zifunwa.
3. Umphezulu weGalvanizing(igalvanizing ingohlulwa ibeyi-galvanizing yediphu eshushu (i-hot-dip galvanizing) kunye ne-cold-dip galvanizing (electrogalvanizing), kunye ne-hot-dip galvanizing yeyona ndlela iphambili kushishino (inika isiphumo esisebenzayo sothintelo lomhlwa): Imibhobho edidiweyo icolwa okwesibini ukuze isuse ubumdaka, idiphu emdaka, emva koko idiphini. i-zinc etyhidiweyo kwi-440-460 ° C ukwenza i-zinc alloy coating. I-zinc eyongezelelweyo isuswe ngemela yomoya, kwaye ipholile. (I-Cold-dip galvanizing yi-electrodeposited zinc layer kwaye ayiqhelekanga ukusetyenziswa.)
4. Ukuhlolwa kunye nokuPakisha: Khangela umaleko we-zinc kunye nobukhulu, ukulinganisa ukunamathela kunye nokuxhathisa ukubola, uhlele kwaye udibanise iimveliso ezifanelekileyo, kwaye uzibeke kwindawo yokugcina kunye neelebhile.
Inkqubo yemveliso yemibhobho engqukuva engenamthungo engenazinki ilandela la manyathelo:
1. Ukunyangwa kweMathiriyeli ekrwada: Iibhilidi zensimbi ezingenamthungo (ininzi insimbi ephantsi kwekhabhoni) zikhethiweyo, zinqunywe ubude obusisigxina, kunye nomlinganiselo we-oxide ongaphezulu kunye nokungcola kuyasuswa. Iibhilithi ke zifudunyezwa kwiqondo lobushushu elifanelekileyo lokugqojozwa.
2. Ukugqobhoza: Iibhilithi ezifudunyeziweyo ziqengqeleka kwiityhubhu ezingenanto ngokusebenzisa ilitye lokugqobhoza. Iityhubhu zigqithiswa kwi-tube rolling Mill ukuze kulungiswe ubukhulu bodonga kunye nokungqukuva. Idayamitha yangaphandle iye ilungiswe ngokulinganisa ukwenza iityhubhu ezisemgangathweni ezingenamthungo ezimnyama. Emva kokupholisa, iibhubhu zinqunywe ubude.
3. Ukugalela: Iityhubhu ezimnyama ezingenamthungo zingena kunyango lwesibini lokuchola ukususa umaleko weoxide. Emva koko zihlanjululwe ngamanzi kwaye zifakwe kwi-galvanizing agent. Emva koko bantywiliselwa kwi-440-460 ° C ye-zinc etyhidiweyo ukwenza i-zinc-iron alloy coating. I-zinc eyongeziweyo isuswe ngommese womoya, kwaye iibhubhu zipholile. (I-galvanizing ebandayo yinkqubo ye-electrodeposition kwaye ayiqhelekanga ukusetyenziswa.)
4. Ukuhlolwa kunye nokuPakisha: Ukufana kunye nokunamathela kwengubo ye-zinc kuhlolwa, kunye nemilinganiselo yeepayipi. Imibhobho evunyiweyo ke iyahlelwa, idityaniswe, ifakwe ilebhile, kwaye igcinwe ukuqinisekisa ukuba iyahlangabezana nothintelo lomhlwa kunye nemigangatho yokusebenza koomatshini.
Iindlela zothutho lweemveliso zibandakanya indlela, uloliwe, ulwandle, okanye uthutho lwemodemu ezininzi, ngokusekelwe kwiimfuno zabathengi.
Uthutho lwendlela, kusetyenziswa iilori (umzekelo, ii-flatbeds), ziguquguqukayo kumgama omfutshane-ophakathi, okwenza kube lula ukuhanjiswa ngokuthe ngqo kwiindawo / kwiindawo zokugcina iimpahla ezinokulayisha / ukukhulula lula, ezifanelekileyo kwii-odolo ezincinci okanye ezingxamisekileyo kodwa zibiza umgama omde.
Uthutho lukaloliwe luxhomekeke koololiwe bempahla (umzekelo, iinqwelo ezigqunyiweyo/ezivuliweyo ezinemitya yokunqanda imvula), zilungele umgama omde, ukuthunyelwa kwenani elikhulu ngexabiso eliphantsi kunye nokuthembeka okuphezulu, kodwa kufuna ukuhanjiswa komgama omfutshane.
Uthutho lwamanzi (ngaphakathi/elwandle) ngeenqanawe ezithwala imithwalo (umzekelo, isambuku/sesikhongozeli seenqanawe) zineendleko eziphantsi kakhulu, ukulinganisa umgama omde, uthutho olukhulu lwaselunxwemeni/lomlambo, kodwa lunezibuko/indlela-imida kwaye icotha.
Uthutho lweendlela ezininzi (umzekelo, uloliwe+indlela, ulwandle+indlela) zilinganisa iindleko kunye nexesha elifanelekileyo, zilungele ukunqumla ingingqi, umgama omde, iodolo yexabiso eliphezulu yendlu ngendlu.
