ʻO nā kumu ʻino a me nā ʻano Anticorrosion no ka Aluminum Alloy ma nā kaʻaahi kiʻekiʻe

Hana ʻia ke kino a me ka hook-beam o nā kaʻa kaʻa kiʻekiʻe me ka hoʻohana ʻana i ka alumini alumini, i ʻike ʻia no kāna mau mea maikaʻi e like me ka haʻahaʻa haʻahaʻa, kiʻekiʻe ikaika-a-kaumaha ratio, maikaʻi ke kūpaʻa corrosion, a me ka hana haʻahaʻa haʻahaʻa maikaʻi loa.Ma ka hoʻololi ʻana i nā mea kila kuʻuna me ka alumini, ua hoʻemi nui ʻia ke kaumaha o ke kino kaʻaahi, e alakaʻi ana i ka hoʻemi ʻana i ka ikehu, hoʻemi i ka haumia o ke kaiapuni, a me ka hoʻokumu ʻana i nā pono waiwai a me ka pilikanaka.

Eia nō naʻe, loaʻa i nā alumini alumini a me nā alumini nā mea kemika reactive.ʻOiai ke hoʻokumu ʻana i kahi kiʻiʻoniʻoni oxide nui ke ʻike ʻia i ka oxygen i loko o ke kaiapuni, e hāʻawi ana i ke kūpaʻa corrosion ʻoi aku ka maikaʻi ma mua o ke kila maʻamau, hiki ke hana ʻia ka corrosion ke hoʻohana ʻia ke alumini alumini i nā kaʻaahi kiʻekiʻe.ʻO nā kumu wai ʻino, e like me ka pāpaʻi ʻana, ka condensation o ka lewa, a me ka wai e kahe ana mai ka lepo i ka wā e kaʻa ai, hiki ke hoʻopau i ke kiʻiʻoniʻoni oxide.ʻO ka corrosion i loko o ka alumini alumini i hoʻohana ʻia i ke kino o nā kaʻa kaʻa kiʻekiʻe e hōʻike nui ʻia e like me ka corrosion like ʻole, pitting corrosion, crevice corrosion, a me ke koʻikoʻi koʻikoʻi, hana ia i kahi kaʻina paʻakikī i hoʻopili ʻia e nā mea kūlohelohe a me nā waiwai alloy.

Aia nā ʻano hana like ʻole no ka anticorrosion o ka alumini alumini, e like me ka hoʻopili ʻana i nā pale anticorrosive e hoʻokaʻawale pono i ka substrate alumini alumini mai ka ʻaoʻao o waho.ʻO kahi uhi anticorrosive maʻamau ʻo ka epoxy resin primer, hoʻohana nui ʻia no kona kūpaʻa wai maikaʻi, ka hoʻopili substrate ikaika, a me ka hoʻohālikelike ʻana me nā uhi like ʻole.

Eia nō naʻe, ke hoʻohālikelike ʻia i nā ʻano hana pale kino kino, ʻoi aku ka maikaʻi o ka hoʻomaʻamaʻa ʻana i ka passivation kemika.Ma hope o ka hoʻomaʻamaʻa ʻana i ka alumini a me nā alumini alumini, ʻaʻole i hoʻopilikia ʻia ka mānoanoa o ka huahana a me ka pololei mechanical, ʻaʻohe loli i ka helehelena a i ʻole ke kala.ʻOi aku ka maʻalahi o kēia ʻano hana a hāʻawi i kahi kiʻiʻoniʻoni passivation kūpaʻa a me ka corrosion-resistant i hoʻohālikelike ʻia me nā uhi anticorrosive kuʻuna.ʻOi aku ka paʻa o ke kiʻiʻoniʻoni passivation i hana ʻia ma o ka alumini alumini passivation treatment a ʻoi aku ka nui o ke kūpaʻa corrosion ma mua o nā uhi anticorrosive kuʻuna, me ka pōmaikaʻi hou o ka hana hoʻoponopono ponoʻī.

ʻO kā mākou chromium-free passivation solution, KM0425, he kūpono ia no ka hoʻololi ʻana i nā mea alumini, nā alumini alumini, a me nā huahana alumini make-cast, e hoʻonui ana i ko lākou kūpaʻa ʻana.He huahana hou a kiʻekiʻe no ka passivation kumu nui o nā mea alumini.Hoʻokumu ʻia me nā ʻakika organik, nā mea honua laha ʻole, nā mea hoʻopiʻi corrosion kiʻekiʻe, a me kahi mea liʻiliʻi o nā mea hoʻokele passivation kiʻekiʻe-molecular-kaumaha, ʻaʻohe waika, ʻaʻohe mea ʻawaʻawa, a ʻaʻohe ʻala.Hoʻopili i nā kūlana RoHS kaiapuni o kēia manawa, me ka hoʻohana ʻana i kēia hopena passivation e hōʻoia i ka hana passivation ʻaʻole e hōʻino i ka waihoʻoluʻu kumu a me nā ana o ka mea hana me ka hoʻomaikaʻi nui ʻana i ke kūʻē ʻana o nā mea alumini i ka paʻakai paʻakai.
