Fa'asalalau ile 2018-08-15Zinc alumini faʻapipiʻi e aofia ai le paʻu zinc paʻu, paʻu alumini, acids inorganic ma fusi, faʻapipiʻiina vai o loʻo faʻapipiʻiina i luga o le puipui puipui, o se fausaga fou ma mea totino ina ua uma ona faia le sintering, e faaigoa i le Igilisi "dacromet".I le avea ai o se tekinolosi fou e faʻafouina atoatoa nisi o togafitiga faʻaleaganuʻu masani, talu mai lona faʻafeiloaʻiga i Saina i le 1993, o le zinc-aluminum coating technology e tele mea lelei i le maualuga-corrosion, paʻu manifinifi ma maualuga-mama le siosiomaga-faauo gaosiga.E faʻaaogaina lautele i le taʻavale, fausiaina, felauaiga, malosi, fesoʻotaʻiga, meafale ma isi pisinisi.
Anti ele masini o le zinc alumini faʻapipiʻi
1. Faʻalavelave faʻalavelave: ona o le faʻapipiʻiina o le lamellar zinc ma le alumini, o le mea e pala, e pei o le vai ma le okesene, ua taofia mai le oʻo atu i le meaʻai ma e mafai ona avea o se talipupuni vavae.
2. Pasivation: i le faagasologa o le paluga alumini zinc, o le vaega inorganic acid e tali atu ma le zinc, alumini paʻu ma le uʻamea faavae e maua ai se ata pasif compact, lea e lelei tetee corrosion.
3. Puipuiga Cathodic: o le galuega puipuia autu o le zinc, alumini ma le chromium coating e tutusa ma le zinc coating, lea o le cathodic puipuiga substrate.
