ʻO ka hana anticorrosive o ka ʻenehana dacromet

Kau ʻia ma 2018-05-23Hiki ke hōʻuluʻulu ʻia ka hopena pale o ka papa dacromet ma ke kila matrix penei:

1. Ka hopena pale: ma muli o ka uhi ʻana o ka zinc a me ka papa alumini, hiki ke pale ʻia ke kaʻina o ka hiki ʻana i ka matrix o ka media corrosion e like me ka wai a me ka oxygen.

2. Passivation: i ka dacro kaʻina, chromic acid reacts me ka zinc, aluminika pauka a me ka matrix metala no ka hoʻopaʻa 'ana kiʻiʻoniʻoni passivation, a me keia passivation kiʻiʻoniʻoni maikaʻi corrosion kū'ē.

3. Palekana Cathodic: ʻo ka hopena pale nui o ka zinc-alumina coating e like me ka zinc coating, ʻo ia ka pale cathodic o ka substrate.

ʻO Changzhou junhe zinc chrome dacromet coating he ʻano o ka ʻepekema a me ka ʻenehana e ka pauka zinc, ka pauka alumini, ka waikawa chromic a me ka wai deionized e like me ke ʻano nui o ka uhi anticorrosive ʻano hou, ka ʻili o ka waihoʻoluʻu hoʻokahi, ke kālā a me ke kālā, ʻaʻole kūpono ia. pono hoʻokahi o ka hoʻomohala ʻoihana kaʻa.Eia nō naʻe, hiki ke loaʻa nā kala like ʻole ma hope o ka hoʻoponopono ʻana a i ʻole ka uhi ʻana i ka composite e hoʻomaikaʻi ai i ka hoʻonaninani a me ka hoʻohālikelike ʻana i nā ʻāpana kaʻa.
