Uyini umehluko phakathi kwamakhoyili namashidi ensimbi anathayela kanye ne-galvalume

I-surface coil yamakhoyili e-aluminium ayi-aluminium yakhiwe nge-aluminium engu-55%, i-zinc engu-43.5% kanye nenani elincane lezinye izakhi.Ingaphezulu le-aluminum ye-zinc enamathela yisakhiwo sezinyosi ngaphansi kokubuka okuncane, futhi "ikhekheba lezinyosi" elenziwe nge-aluminium liqukethe i-zinc.Kulokhu, nakuba i-aluminium-zinc enamathela nayo idlala indima yokuvikela i-anode, ngakolunye uhlangothi, ngenxa yokuncipha kokuqukethwe kwe-zinc, ngakolunye uhlangothi, izinto ze-zinc zigoqwe nge-aluminium futhi akulula ukwenza i-electrolyze, ngakho-ke indima yokuvikela i-anode iyancipha kakhulu.Ngakho-ke, uma i-aluminium isipuletiwe Ipuleti le-zinc liyasikwa, futhi lizogqwala maduze lapho unqenqema olusikiwe lulahleka futhi luvikelekile.Ngakho-ke, ipuleti ye-aluminium-zinc kufanele inqunywe kancane ngangokunokwenzeka.Uma ususikiwe, unqenqema lungavikelwa ngokusebenzisa upende ovimbela ukugqwala noma upende ocebile nge-zinc.Impilo ende yesevisi yamapuleti.

Ingaphezulu lamakhoyili ensimbi ye-galvalume/aluzinc/zincalum kunikeza imbali ehlukile ebushelelezi, eyisicaba futhi ebukekayo yenkanyezi, futhi umbala oyisisekelo umhlophe-isiliva.Isakhiwo esikhethekile sokumboza sikwenza kube nokumelana nokugqwala okuhle kakhulu.Ukuphila kwesevisi evamile yepuleti ye-aluminium-zinc ingafinyelela ku-25a, futhi inokumelana nokushisa okuhle futhi ingasetshenziswa endaweni yokushisa ephezulu engu-315 ° C;ukunamathela kokugqoka kanye nefilimu yepende kuhle, futhi kunezindawo ezinhle zokucubungula, futhi ingashaywa, inqunywe, ihlanganiswe, njll;I-surface conductivity inhle kakhulu.

Ukwakheka kokumboza kwakhiwe nge-aluminium engu-55%, i-zinc engu-43.4%, kanye ne-silicon engu-1.6% ngesisindo.Inqubo yokukhiqiza ikhoyili yensimbi ye-galvalume iyafana neyamakhoyili ensimbi anamakhoyili namakhoyili a-aluminium, okuyinqubo eqhubekayo yokumboza encibilikisiwe.Ikhoyili ye-galvalume/aluzinc enama-55% e-aluminium-zinc alloy coil inokumelana nokugqwala okungcono kuneshidi lensimbi eliwugqinsi oluwugqinsi olufanayo lapho livezwe endaweni efanayo nhlangothi zombili.I-55% ye-aluminium-zinc alloy ehlanganiswe ne-aluminium-zinc steel plate ayinakho ukumelana nokugqwala okuhle kuphela, kodwa futhi inokunamathela nokuguquguquka kwemikhiqizo enemibala.

Umehluko phakathi kwamakhoyili egalvalume/aluzinc kanye namagalvanized umehluko omkhulu ekujikeni.Ubuso beshidi lika-galvanized lusatshalaliswa ngokulinganayo ngongqimba lwezinc, olusebenza njengesivikelo se-anodic sezinto eziyisisekelo, okungukuthi, ukuvikela okunye kokugqwala kwezinto ezizinki.Ngaphezu kokusetshenziswa kwezinto eziyisisekelo, izinto eziyisisekelo ngaphakathi zingalimala kuphela lapho i-zinc igqwalile ngokuphelele.
