Zithini iingenelo zeemveliso ze-zinc-aluminium-magnesium?

1. Ukumelana nokukrwela kokwaleka
Ukugqwala komphezulu weeshiti ezigqunyiweyo kudla ngokuvela xa kukrwelwa. Ukukrwela akunakuphepheka, ingakumbi ngexesha lokucubungula. Ukuba ishiti egqunyiweyo ineempawu eziqinileyo zokumelana nokukrwela, inokunciphisa kakhulu amathuba okonakala, ngaloo ndlela yandise ubomi bayo. Uvavanyo lubonisa ukubaAmaphepha e-ZAMZiyaphumelela kakhulu kunezinye; zibonisa ukumelana nokukrwela phantsi kwemithwalo ngaphezu kwe-1.5% ye-aluminium egayiweyo-5% kwaye ngaphezulu kwesithathu kune-galvanized kunye ne-zinc-aluminium sheets. Oku kuphakama kuvela kukuqina okuphezulu kwengubo yazo.

2. Ukudityaniswa
Xa kuthelekiswa namaphepha aqengqelekayo ashushu nalawo aqengqelekayo abandayo,I-ZAMIipleyiti azinawo amandla okuwelda aphantsi. Nangona kunjalo, ngeendlela ezifanelekileyo, zisenokwelukwa ngokufanelekileyo, zigcine amandla kunye nokusebenza kakuhle. Kwiindawo zokuwelda, ukulungiswa ngeengubo zohlobo lwe-Zn-Al kunokufezekisa iziphumo ezifana nezengubo yokuqala.

3. Ukupeyinta kakuhle
Ukupeyintwa kweZAM kufana noko kwe-aluminium ene-galvanized-5% kunye ne-zinc-aluminium-silicon coatings. Ingapeyintwa, nto leyo ephucula ngakumbi inkangeleko kunye nokuqina kwayo.

4. Ukungathathelwa indawo
Kukho iimeko ezithile apho i-zinc-aluminium-magnesium ingenakutshintshwa zezinye iimveliso:
(1) Kwiinkqubo zangaphandle ezifuna iinkcukacha eziqinileyo kunye neengubo eziqinileyo zomphezulu, ezifana nee-guardrails zendlela, ezazikade zixhomekeke kwi-bulk galvanization. Ngokufika kwe-zinc-aluminium-magnesium, i-continuous hot-dip galvanization iye yaba yinto enokwenzeka. Iimveliso ezifana nezixhobo zelanga kunye nezixhobo zebhulorho ziyazuza kolu phuculo.
(2) Kwimimandla efana neYurophu, apho ityuwa yendlela isasazeka khona, ukusebenzisa ezinye izinto zokugquma ezingaphantsi kwezithuthi kukhokelela ekungcoleni ngokukhawuleza. Iipleyiti ze-zinc-aluminium-magnesium zibalulekile, ingakumbi kwiivillas eziselunxwemeni kunye nezakhiwo ezifanayo.
(3) Kwiindawo ezikhethekileyo ezifuna ukumelana ne-asidi, njengezindlu zeenkukhu zasefama kunye neembiza zokutya, kufuneka kusetyenziswe iipleyiti ze-zinc-aluminium-magnesium ngenxa yendlela erhabaxa ngayo inkunkuma yeenkukhu.
