Umahluko phakathi kwekhoyili yegalvanized kunye negalvalumed coil
Umaleko wezinto ze-zinc usasazwa ngokulinganayo kumphezulu wephepha elifakwe igalvanized, elisebenza njengokhuselo lwe-anodic kwisiseko sesinyithi, oko kukuthi, enye i-corrosion ye-zinc ikhusela ukusetyenziswa kwesiseko sesinyithi.Apha, i-zinc ifana nobalulekileyo Izihlangu zenyama ezijikeleze abalinganiswa kufuneka zibingelelwe ngaphambi kokuba abalinganiswa abaphakathi bajike.

Ukugquma komphezulu wephepha le-galvanized wenziwe nge-55% ye-aluminium, i-43.5% ye-zinc kunye nenani elincinci lezinye izinto.Kwinqanaba le-microscopic, i-galvanized coating ibonisa isakhiwo se-honeycomb, kwaye "i-honeycomb" eyenziwe nge-aluminium iqulethe i-zinc, kulo mzekelo, nangona i-aluminium-zinc i-coating idlala indima yokukhusela i-anodic, kwelinye icala, ngenxa ukuncitshiswa komxholo we-zinc, ngakolunye uhlangothi, ngenxa yokuba izinto ze-zinc zihlanganiswe nge-aluminium, akulula ukuba i-electrolyzed, ngoko indima yokukhusela i-anodic iyancipha kakhulu.Apha, i-zinc eyenziwe ngegalvanized ifana nesikrweqe somzimba kwimishini ebalulekileyo.Emva kokuba iphuzu liphukile, ukukhuselwa ngelo xesha kuphelile.Ngoko ke, emva kokuba i-galvanized sheet inqunyulwe, ukukhuselwa komgca osikiweyo kulahlekile ngokusisiseko, ngoko kuya kugqwala ngokukhawuleza.Ngoko ke, iphepha le-galvanized kufuneka linqunywe kancinci kangangoko.Emva kokusikwa, sebenzisa ipeyinti echasene ne-rust okanye ipeyinti ecebileyo yeZinc ikhusela imida, ukwenzela ukuba ubomi benkonzo yebhodi bunokwandiswa.
Ukugquma komphezulu wephepha le-galvanized wenziwe nge-55% ye-aluminium, i-43.5% ye-zinc kunye nenani elincinci lezinye izinto.Ngaphantsi kwenqanaba le-microscopic, i-galvanized galvanized covering ibonakalisa isakhiwo se-honeycomb, kwaye "i-honeycomb" eyenziwe nge-aluminium iqulethe i-zinc, kulo mzekelo, nangona i-aluminium-zinc i-coating idlala indima yokukhusela i-anodic, kwelinye icala, ngenxa ukuncitshiswa komxholo we-zinc, ngakolunye uhlangothi, ngenxa yokuba izinto ze-zinc zihlanganiswe nge-aluminium, akulula ukuba i-electrolyzed, ngoko indima yokukhusela i-anodic kakhulu Nciphisa.Apha, igalvanized ifana nesikrweqe somzimba kwimishini ebalulekileyo, xa inqaku lophukile, ukhuselo ngelo xesha luphelile.Ngoko ke, emva kokuba i-galvanized sheet inqunywe, ilahlekile ngokusisiseko kwi-cut cut, ngoko ke, i-galvanized sheet kufuneka inqunyulwe kancinane kangangoko.Nje ukuba usikiwe, sebenzisa ipeyinti echasene nomhlwa okanye ipeyinti etyebileyo ye-zinc ukukhusela imiphetho yokwandisa ubomi benkonzo yephepha.
1. Iimveliso eziqhelekileyo zokugquma i-zinc (GI) Iimveliso eziqhelekileyo ze-galvanized ze-dip-dip zinokwahlulwa zibe yi-spangle eqhelekileyo, i-spangle encinci, i-spangle kunye neemveliso ezigudileyo zomgangatho ngokwesimo somphezulu.Ngenxa yokunganyangeki kwayo kakuhle kokutya, ukusetyenzwa okugqwesileyo kunye nokwenza umsebenzi, ixabiso eliphantsi lemveliso, kunye nenkangeleko entle, isetyenziswa kakhulu kulwakhiwo, iimoto, izixhobo zasekhaya kunye namanye amashishini.Ngokukodwa kwi-spangle encinci kwaye akukho mveliso yokugquma isipantshi, iinkozo ezingaphezulu zilungile, zixinene, zigudile, kwaye zineengubo ezingcono zokugquma kunye nokuxhathisa umhlwa, ngakumbi kwizixhobo zasekhaya, ukugquma kombala kunye namanye amashishini.
2. I-Zinc Aluminiyam ye-Aluminiyam ye-Aluminiyam ye-Alloy Coated Sheet (GF)
I-Zinc-aluminiyam ialloy coated sheet ikwabizwa ngokuba yi-low-aluminium galvanized sheet sheet, kunye nokwaleka kuqulathe.
5% Al, 95% Zn, kunye nemikhondo yezinto ezinqabileyo zomhlaba.Iinzuzo eziphambili kukuba iplastiki kunye nokunamathela kwengubo kuhle kakhulu, kwaye ukuxhathisa kwe-corrosion ngaphambi nangemva kokuguqulwa akutshintshi;ukuxhathisa umhlwa emoyeni yi-2 ukuya ku-3 kumaxesha aqhelekileyo ashushu-dip amashiti afakwe igalvanized, kwaye inocoatability elungileyo kunye nokuweldability.Phakathi kwawo onke amashiti e-galvanized, inokuqina okungcono kakhulu, ukuxhathisa ukubola kunye nokwakheka okuthelekiswa namaphepha e-electro-galvanized.Le mveliso isetyenziselwa ikakhulu ukunyanzeliswa kwe-corrosion kunye nemozulu-resistant nemozulu kunye nee substrates imathiriyeli.
I-3.I-aluminium-zinc i-alloy icwecwe (GL) Isakhiwo sokugubungela i-aluminium-zinc alloy coated plate yi-Al-Zn i-alloy, kunye nokubunjwa kwe-coating ngu-55% Al, 43.3% Zn, 1.6% Si.Umphezulu wayo ugudileyo kwaye unokumelana ne-atmospheric corrosion ebalaseleyo, ephindwe ka-2-6 ngaphezulu kweshiti elinye le-galvanized yediphu eshushu.Inokumelana ne-corrosion yobushushu obuphezulu obufana nepleyiti ye-aluminiyam eshushu, kwaye ingasetyenziselwa ixesha elide ngaphandle kokuguquka kombala okanye ukuguqulwa kwiqondo lokushisa eliphezulu lama-315 degrees.Ukuxhathisa umhlwa ingcono kunaleyo eshushu-diphu sheet lagalvanized kunye sheet eshushu-dip aluminized, kunye nokumelana umhlwa umhlaba ingcono kunaleyo eshushu-diphu sheet amazi.Ukubonakaliswa kwayo kwe-thermal kuphezulu kune-75%, okuphindwe kabini kunephepha eliqhelekileyo legalvanized.Inokupeyintwa okulungileyo kunye nokuqhubekeka, kwaye ngokuthe ngcembe ithatha indawo yephepha elenziwe ngamathangi kwaye isetyenziswa kakhulu kwihlabathi.
4. I-galvanized sheet eshushu-i-galvanized sheet - i-galvanized sheet eshushu ifakwe kwi-galvanized sheet eveliswa ngokuthe ngqo ngokukhetha kunye ne-galvanizing kunye ne-hot-rolled sheet njenge-substrate.Ibhodi ingasetyenziswa ngokubanzi kulwakhiwo, iimoto, izisele zentsimbi, iimoto zabakhweli bakaloliwe, iibhodi zokugada uhola wendlela, njl. njl zigqityiwe kwaye zifakwe kwimveliso zifakwe kwi-galvanized sheet kunye ne-cold-rolled sheet njenge-substrate.Xa kuthelekiswa neshiti eliqengqelekayo elibandayo, umahluko ekusebenzeni phakathi kweshiti legalvanized elishushu eliqengqiwe kunye nelegalvanized sheet elibandayo alikho mkhulu kakhulu.Ngenxa yokuba i-galvanized sheet eshushu igcina inkqubo yokuqengqeleka ebandayo, ixabiso lemveliso liphantsi, kwaye linenzuzo ecacileyo yexabiso.
