Hoʻohana ʻenehana no ka uhi ʻana i ka zinc aluminika

Kau ʻia ma 2018-08-15Hoʻokumu ʻia ka Zinc alumini coating me ka pauka zinc flake, ka pauka alumini, nā waikawa inorganic a me ka binder, ua uhi ʻia ka wai i uhi ʻia ma ka papa pale pale, kahi hale hou a me nā waiwai ma hope o ka sintering i hoʻokumu ʻia, ua kapa ʻia ʻo English "dacromet".Ma ke ʻano he ʻenehana hou e hoʻomaʻamaʻa loa i kekahi mau lāʻau lapaʻau kuʻuna metala, mai kona hoʻokomo ʻia ʻana i Kina i ka makahiki 1993, he nui nā pōmaikaʻi o ka ʻenehana hoʻopili zinc-aluminum i ka corrosion kiʻekiʻe, ka uhi lahilahi a me ka hoʻomaʻemaʻe hoʻomaʻemaʻe kiʻekiʻe.Hoʻohana nui ʻia ia i ka automotive, ke kūkulu ʻana, ka lawe ʻana, ka mana, nā kamaʻilio, nā mea hana hale a me nā ʻoihana ʻē aʻe.

ʻO ka hana anti rust o ka uhi alumini zinc

1. Ka hopena pale: ma muli o ka hoʻopili ʻana o ka lamellar zinc a me ka aluminika, ua pale ʻia ke ʻano corrosion, e like me ka wai a me ka oxygen, mai hiki i ka substrate a hiki ke hana ma ke ʻano he pale pale.

2. Passivation: i ke kaʻina hana o ka zinc aluminum coating, hoʻopili ka mea ʻakika inorganic me ka zinc, ka pauka alumini a me ka metala kumu e hana ai i kahi kiʻiʻoniʻoni passive paʻa, a ʻoi aku ka maikaʻi o ka corrosion.

3. Palekana Cathodic: ʻo ka hana pale nui o ka zinc, aluminika a me ka chromium coating e like me ka zinc coating, ʻo ia ka substrate pale cathodic.
