Yakatumirwa pa 2018-08-15Zinc aluminium coating inoumbwa neflake zinc poda, aruminiyamu poda, inorganic acids uye binder, inoputira mvura inoputirwa pamusoro pechidziviriro chepamusoro, chimiro chitsva uye zvivakwa mushure mekugadzira sintering, iyo Chirungu yakanzi "dacromet".Se tekinoroji nyowani inovandudza zvachose mamwe echinyakare simbi pamusoro pekurapa, kubva payakaunzwa kuChina muna 1993, zinc-aluminium coating tekinoroji ine zvakawanda zvakanakira mukuora-kwepamusoro, kuonda kwakatetepa uye kugadzirwa kwakachena kwenzvimbo.Inoshandiswa zvakanyanya mumotokari, kuvaka, chekufambisa, magetsi, kutaurirana, midziyo yemumba uye mamwe maindasitiri.
Anti rust mechanism ye zinc aluminium coating
1. Barrier effect: nekuda kwekupindirana kwe lamellar zinc uye aluminium, iyo corrosion medium, yakadai semvura uye oksijeni, inodziviswa kusvika kune substrate uye inogona kuita sechidzitiro chekuzviparadzanisa.
2. Passivation: mukugadzira zinc aluminium coating, iyo inorganic acid chikamu chinopindirana ne zinc, aluminium poda uye base metal kuti ibudise compact passive film, ine yakanaka corrosion resistance.
3. Kudzivirirwa kweCathodic: basa guru rekudzivirira re zinc, aluminium uye chromium coating yakafanana neyo zinc coating, iyo cathodic kudzivirira substrate.
