Umahluko Phakathi kwePhepha leNsimbi eliQokelelwe ngeAluminiyam-Zinc kunye nePhepha leNsimbi eliGxothiweyo

Xa ibekwe kwindawo efanayo kumacala omabini, ishiti yentsimbi yeGalvalume ene-55% ye-aluminium-zinc alloy coating ibonakalisa ukumelana nokugqwala okuphezulu xa kuthelekiswa neshiti yentsimbi egayiweyo enobukhulu obufanayo. Ukongeza ekumelaneni kwayo nokugqwala okugqwesileyo, iimveliso ezinemibala yeshiti yentsimbi egayiweyo ye-55% ye-aluminium-zinc alloy zinobuncamathelo obubalaseleyo kunye nokuguquguquka.

 

Umahluko ophambili phakathiamashiti entsimbi agqunyiweyokwayeamaphepha entsimbi agqunywe nge-aluminium-zinc alloyikwiingubo zazo. Umphezulu weshiti yentsimbi egqunywe nge-galvanized ugqunywe ngokulinganayo ngomaleko wezinto ze-zinc, ezibonelela ngokhuseleko lwe-cathodic kwisinyithi esisisiseko. Oku kuthetha ukuba izinto ze-zinc zidlula kwi-corrosion ukuze zikhusele isinyithi esisisiseko, kwaye kuphela xa yonke i-zinc ibolile apho isinyithi esisisiseko siyonakala.

Uphahla lomphezulu weGalvalume Steel Coils luqulathe i-55% ye-aluminium, i-43.5% ye-zinc, kunye nenani elincinci lezinye izinto. Phantsi kwe-microscope, umphezulu wophahla ubonakala njengesakhiwo se-honeycomb, kunye ne-aluminium eyenza iiseli "zobusi" ezivalela i-zinc. Kule meko, nangona uphahla lwe-aluminium-zinc lukwabonelela ngokhuseleko lwe-cathodic, ukuncipha komxholo we-zinc kunye nenyani yokuba i-zinc ivalelwe yi-aluminium kuyenza ingachaphazeleki kakhulu yi-electrolysis, ngaloo ndlela inciphisa kakhulu impembelelo yayo yokhuseleko lwe-cathodic. Ngenxa yoko, xa iphepha lesinyithi eligqunywe nge-aluminium-zinc lisikiwe, imiphetho esikiweyo ilahlekelwa ngokukhawuleza lukhuselo lwayo kwaye inokuba nokugqwala. Ke ngoko, ukusika iiGalvalume Steel Coils kufuneka kuncitshiswe, kwaye ukuba ukusika kuyimfuneko, imiphetho kufuneka ikhuselwe ngepeyinti yokulwa nomhlwa okanye ipeyinti etyebileyo ye-zinc ukwandisa ubomi benkonzo yephepha.
