I-Hot-dip galvanizing kukwenza isinyithi esityhidiweyo siphendule kunye ne-matrix yentsimbi ukuvelisa umaleko we-alloy, ukwenzela ukuba i-matrix kunye ne-coating zidibaniswe.I-Hot-dip galvanizing kukukhetha iindawo zentsimbi kuqala.Ukuze ususe i-iron oxide phezu kwendawo yentsimbi, emva kokukhetha, ihlanjululwa kwitanki ye-ammonium chloride okanye i-zinc chloride isisombululo se-aqueous okanye isisombululo esixutywe ngamanzi se-ammonium chloride kunye ne-zinc chloride, kwaye emva koko ithunyelwe kwidiphu eshushu. itanki yokwambathisa.I-Hot-dip galvanizing ineenzuzo zokugquma okufanayo, ukubambelela okuqinileyo kunye nobomi obude benkonzo.
Izinto zentsimbi ezisetyenziswa kakhulu kwishishini ziya kugqwala ukuya kumaqondo ahlukeneyo xa zisetyenziswa kwindawo ezifana ne-atmosfera, amanzi olwandle, umhlaba kunye nezinto zokwakha.Ngokwezibalo, ilahleko yonyaka yezinto zetsimbi emhlabeni ngenxa ye-corrosion akhawunti malunga ne-1/3 yemveliso yayo yonke.Ukuze kuqinisekiswe ukusetyenziswa okuqhelekileyo kweemveliso zetsimbi kunye nokwandisa ubomi babo benkonzo, iteknoloji yokukhusela i-anti-corrosion yensimbi isoloko ifumana ingqalelo ebanzi.
I-Hot-dip galvanizing yenye yezona ndlela zisebenzayo zokulibazisa ukubola kokusingqongileyo kwentsimbi kunye nemathiriyeli yentsimbi.Kukuntywilisela isinyithi kunye neemveliso zetsimbi eziye zahlanjululwa kwaye zisebenza kwisisombululo se-zinc etyhidiweyo.Umphezulu ufakwe i-zinc alloy coating kunye nokubambelela kakuhle.Xa kuthelekiswa nezinye iindlela zokukhusela isinyithi, inkqubo ye-galvanizing eshushu-dip ineempawu zokukhusela ukudityaniswa kwesithintelo somzimba kunye nokukhuselwa kwe-electrochemical yokwambathisa, amandla okubopha i-coating kunye ne-substrate, ukubumbana, ukuqina, ukugcinwa kunye nokungakhathali. uqoqosho lokwaleka.Ineenzuzo ezingenakulinganiswa malunga nokuguquguquka kunye nokulungelelanisa ukuma kunye nobukhulu beemveliso.Okwangoku, iimveliso ezishushu-diphu zibandakanya iipleyiti zentsimbi, imicu yentsimbi, iingcingo zentsimbi, imibhobho yentsimbi, njl.Kwangexesha elide, inkqubo ye-galvanizing ye-hot-dip ithandwa ngabantu ngenxa yexabiso layo eliphantsi lokutya, iimpawu zokukhusela ezigqwesileyo kunye nenkangeleko enhle, kwaye isetyenziswa ngokubanzi kwiimoto, ukwakhiwa, izixhobo zasekhaya, iikhemikhali, oomatshini, i-petroleum, i-metallurgy, ishishini lokukhanya, ezothutho, amandla ombane, inqwelomoya kunye nobunjineli baselwandle kunye nezinye iinkalo.
Izinto eziluncedo kwiimveliso ezenziwe ngentsimbi eshushu zihamba ngolu hlobo lulandelayo:
1. Yonke indawo yentsimbi ikhuselwe, kungakhathaliseki ukuba ingaphakathi kombhobho ifakwe kwi-depression, okanye nayiphi na enye ikona apho ukufakwa kunzima ukungena, i-zinc etyhidiweyo ilula ukuyigubungela ngokulinganayo.
idiphu eshushu ifakwe igalvanized
idiphu eshushu ifakwe igalvanized
2. Ixabiso lobunzima bomgangatho we-galvanized likhulu kunolo lwentsimbi.Uluhlu oluphezulu lwe-Eta lunobunzima be-DPN ye-70 kuphela, ngoko kulula ukuba i-dented by collision, kodwa i-Zeta ephantsi kunye ne-delta layer ine-179 DPN kunye ne-211 DPN ngokulandelanayo, ephakamileyo kune-159 DPN ubulukhuni bentsimbi, ngoko impembelelo yayo. ukuxhathisa kunye nokumelana ne-Abrasion kulungile.
3. Kwindawo yekona, i-zinc layer idla ngokugqithisileyo kunezinye iindawo, kwaye inobunzima obuhle kunye nokumelana nokugqoka.Ezinye iingubo zihlala ziyi-thinnest, kunzima kakhulu ukwakha, kunye neyona ndawo isengozini kule kona, ngoko ke ukugcinwa rhoqo kuyadingeka.
4. Nangenxa yomonakalo omkhulu womatshini okanye ezinye izizathu.Inxalenye encinci ye-zinc layer iya kuwa kwaye isiseko sentsimbi siya kubonakaliswa.Ngeli xesha, umaleko we-zinc ojikelezileyo uya kusebenza njenge-anode yedini ukukhusela intsimbi apha kwi-corrosion.Okuchaseneyo kuyinyaniso kwezinye iingubo, apho i-rust yakha ngokukhawuleza kwaye isasazeka ngokukhawuleza phantsi kwengubo, ibangela ukuba i-peel igubungele.
5. Ukusetyenziswa kwe-zinc layer kwi-atmosfera kucotha kakhulu, malunga ne-1/17 ukuya kwi-1/18 yezinga lokubola kwensimbi, kwaye kuqikelelwa.Ubomi bayo bungaphezulu lee kunayo nayiphi na enye into yokugquma.
6. Ubomi bengubo buxhomekeke kubukhulu bengubo kwindawo ethile.Ubukhulu bentsimbi bugqitywe bubunzima bentsimbi, oko kukuthi, ukutyeba kwentsimbi, ukutyeba kwentsimbi, ngoko ke indawo etyebileyo yentsimbi yolwakhiwo lwentsimbi efanayo kufuneka ifumane inyameko etyebileyo ukuqinisekisa ubomi obude. .
7. Umaleko owenziwe ngegalvanized unokupeyintwa nge-duplex system ngenxa yobuhle bayo, ubugcisa, okanye xa usetyenziswa kwindawo ethile enomhlwa.Ngethuba nje inkqubo yepeyinti ikhethwe ngokuchanekileyo kwaye ukwakhiwa kulula, i-anti-corrosion effect ingcono kunomzobo omnye kunye ne-hot-dip galvanizing.Ubomi bube 1.5 ~ 2.5 amaxesha angcono.
8. Ukukhusela intsimbi kunye ne-zinc layer, kukho ezinye iindlela ezininzi ngaphandle kwe-hot-dip galvanizing.Ngokubanzi, indlela yokufaka igalvanizing ye-hot-dip yeyona isetyenziswa kakhulu, eyona mpembelelo ingcono yokuchasa umhlwa kunye nenzuzo yezoqoqosho.
