I-coil ye-galvalume / i-coil ye-Aluzinc / i-Zincalum i-coil ye-Zn-Al i-alloy ifakwe, kwaye ukubunjwa kwe-coil yi-55% ye-Al, i-43.3% ye-Zn, kunye ne-1.6% yeSi.Bseides umbala woqobo, ikhoyili ye-azizinc inemibala eluhlaza okwesibhakabhaka, eluhlaza, yegolide kunye nebomvu.Ngenxa yokumelana nokugqwesa kwayo okugqwesileyo, olu hlobo lwentsimbi ngokuthe ngcembe luthatha indawo yentsimbi ekhandisiweyo kwaye lusetyenziswa ngokubanzi kwihlabathi liphela.
Umphezulu ugudile kwaye unokumelana ne-atmospheric corrosion.Ukumelana ne-atmospheric corrosion yi-2-6 amaxesha aphezulu kunaleyo ye-galvanized sheet eshushu-dip enobunzima obufanayo bokugquma.Kwangaxeshanye, inokumelana nobushushu obuphezulu be-corrosion efana nephepha le-aluminiyam eshushu-dip, i-aluminium-zinc alloy coated steel sheet Ingasetyenziselwa ixesha elide kubushushu obuphezulu obungama-315 ℃, kunye nexesha elide. -ukusetyenziswa kwexesha kwiqondo lobushushu le-500℃～600℃;inokumelana kakuhle namanzi kunye nokumelana nokugqwala komhlaba, kwaye ukuxhathisa kwawo kumdaka wamanzi kungcono kuneshiti elishushu lokuntywila kunye neshiti le-aluminiyam eshushu.Umhlwa womhlaba ungcono kune sheet-dip galvanized sheet;inokupeyinta okugqwesileyo kunye nokusebenza kakuhle kokwenziwa komsebenzi, kunye nokuqhubekeka kwayo kunye nokuwelda kuyafana neshiti elifakwe isinyithi sediphu eshushu, linokusetyenzwa ngokugoba okubandayo, isitampu, njl., kwaye inkangeleko entle.
I-aluminium-zinc alloy coated steel sheet ineempawu zombini zentsimbi eshushu-diphu kunye neshiti lentsimbi ye-aluminiyam eshushu.Ke ngoko, apho kusetyenziswa ishidi lentsimbi eshushu-dip, i-aluminiyam-zinc alloy coated sheet sheet ingasetyenziswa, kwaye inokuthi ithathe indawo yentsimbi yentsimbi eshushu-diphu.Inoluhlu olubanzi lwezicelo, ezinje ngeepaneli zophahla, iipaneli zodonga, iintsimbi zentsimbi ezikhanyayo, iiradiyetha zokufudumeza, imizimba yemoto, iitanki zamafutha, iiteyiphu zentsimbi ezixhotyisiweyo, iiplastichouses, iigranari, izitya zokuthumela, izixhobo zasekhaya kunye nezixhobo zombane, ii-Oveni, ukuqhuma. -amabhanti ensimbi anobungqina, izigqubuthelo zangaphandle zomoya kunye neenkqubo zokungenisa umoya, izifudumezi zamanzi elanga, iibhokisi zokupakisha zeemveliso zeekhemikhali, kunye ne-substrates yepleyiti yombala, imibhobho edityanisiweyo, iifestile zentsimbi, izinto ezibandayo ezenziwe ngentsimbi kwi-metallurgical industry, njl. isicelo esibanzi kakhulu.
Ixabiso le-aluminium-zinc alloy coated sheet sheet liphezulu kunelo lentsimbi eqhelekileyo eshushu-dip, kodwa ngenxa yokuba ubunzima obuthile be-aluminiyam buncinci kune-zinc, ubunzima obuthile be-aluminium-zinc alloy coating yi-3.75kg / dm3 kuphela , ngelixa ubunzima obuthile be-zinc yi-7.1kg / dm3, ngoko ubunzima bokugquma Ubukhulu be-aluminium-zinc alloy coating ye-150g/m2 (icala eliphindwe kabini) iyafana neyokutshisa-dip ipleyiti yentsimbi enentsimbi. ukutyabeka ubunzima 275g/m2 (double-sided), nto leyo igcina kakhulu isinyithi ebiza kakhulu ukutyabeka.
Ukumelana ne-corrosion ephezulu: ukuxhathisa kwe-corrosion yemveliso ngama-6-8 amaxesha ephepha le-galvanized general, kwaye ayiyi kuhlwa iminyaka engama-20 kwiindawo ezahlukeneyo;
Ukumelana nobushushu obuphezulu be-oxidation: ukusetyenziswa okuqhubekayo okanye okwethutyana kwindawo yobushushu obuphezulu be-315 degrees Celsius akuyi kubangela nayiphi na i-discoloration okanye i-deformation;ukusetyenziswa okuqhubekayo okanye okwethutyana kwindawo yobushushu obuphezulu be-490 degrees Celsius ayiyi kuxutywa kakhulu okanye ivelise i-iron oxide scale;
Ukubonakaliswa kobushushu obuphezulu: Ukubonakaliswa kobushushu bemveliso kuphezulu kune-75%, ephindwe kabini kunephepha le-galvanized;
Ukusetyenzwa lula: kunokudibana nokulungiswa kwesitampu, ukucheba, ukugoba, njl.;
Imbonakalo entle: isilivere emhlophe iphethini yekhephu, intle kwaye inhle, ingasetyenziswa ngokuthe ngqo ngaphandle kokupeyinta;
Ukutshiza ngomphezulu: Yinkqutyana elungileyo yokugquma ipeyinti.I-composite ye-alloy kunye ne-organic matter inokubonelela ngokhuseleko olusebenzayo kunye nokukhusela ukubola phantsi kwe-organic coating.
