Yiziphi izinzuzo zemikhiqizo ye-zinc-aluminium-magnesium?

1. Ukumelana Nokwaluka Kokunamathela
Ukugqwala okungaphezulu kwamashidi amboziwe kuvame ukwenzeka lapho imihuzuko. Ukuklwebheka akunakugwenywa, ikakhulukazi phakathi nokucubungula. Uma ishidi eliboshiwe linezindawo eziqinile ezimelana nokuklwebheka, linganciphisa kakhulu amathuba okulimala, ngaleyo ndlela lelule isikhathi salo sokuphila. Ukuhlola kubonisa lokhoAmashidi e-ZAMukwedlula abanye; akhombisa ukumelana nokuklwebheka ngaphansi kwemithwalo ephindwe izikhathi ezingaphezu kuka-1.5 kune-aluminium engama-galvanized-5% nangaphezu kokuphindwe kathathu kunamashidi akhandisiwe kanye ne-zinc-aluminium. Lokhu kuphakama kubangelwa ubulukhuni obuphakeme bokunamathela kwabo.

2. Ukushisela
Uma kuqhathaniswa namashidi agoqelwe ashisayo nabandayo,ZAMamapuleti abonisa ukushisela okungaphansi kancane. Kodwa-ke, ngamasu afanele, asengakwazi ukushiselwa ngokuphumelelayo, alondoloze amandla nokusebenza. Ezindaweni zokushisela, ukulungisa ngezingubo zohlobo lwe-Zn-Al kungafinyelela imiphumela efana ne-original coating.

3. Ukupendeka
Ukupendeka kwe-ZAM kufana nalokho kwe-aluminiyamu engu-5% ne-zinc-aluminium-silicon coatings. Ingapendiwa, ithuthukise nakakhulu ukubukeka nokuqina.

4. Ukungaphindiseli indawo
Kunezimo ezithile lapho i-zinc-aluminium-magnesium ingenakuthathelwa indawo eminye imikhiqizo:
(1) Ezinhlelweni zangaphandle ezidinga ukucaciswa okuwugqinsi kanye nama-surface aqinile, njengama- guardrail anguthelawayeka, ngaphambilini ebethembele ekufakweni kukagesi ngobuningi. Ngokufika kwe-zinc-aluminium-magnesium, ukuqhubeka kwe-hot-dip galvanization sekungenzeka. Imikhiqizo efana nezisekelo zemishini yelanga kanye nezingxenye zebhuloho ziyazuza kulokhu kuthuthukiswa.
(2) Ezifundeni ezifana neYurophu, lapho usawoti osemgwaqweni usakazwa khona, ukusebenzisa ezinye izimbotshana ezingaphansi kwezimoto kuholela ekugqwaleni ngokushesha. Amapuleti e-Zinc-aluminium-magnesium abalulekile, ikakhulukazi kuma-villas olwandle kanye nezakhiwo ezifanayo.
(3) Ezindaweni ezikhethekile ezidinga ukumelana ne-asidi, njengezindlu zezinkukhu zasepulazini kanye nezitsha zokudla, amapuleti e-zinc-aluminium-magnesium kufanele asetshenziswe ngenxa yokugqwala kwemfucuza yezinkukhu.
