ʻO ka hoʻomohala ʻenehana o Dacromet (zinc chrome coating)

Kau ʻia ma 2018-12-28ʻO Dacromet ka unuhi Kina o DACROMETR, i kapa ʻia ʻo zinc chrome film, Dak rust, Dakman, etc., a e kapa ʻia ʻo "zinc chrome coating" ma ke ʻano o ka Dacromet o Kina.), ʻo ia ka mea i wehewehe ʻia e like me: "Ka uhi anti-corrosion inorganic me ka zinc scaly a me ka zinc chromate ma ke ʻano he mea nui ma o ka uhi ʻana, ka palu ʻana a i ʻole ke kāpī ʻana i ka uhi zinc-chromium i hoʻokumu ʻia i ka wai ma luna o ka ʻili o nā ʻāpana kila a i ʻole nā ​​ʻāpana. Layer."Ua hana ʻia ka ʻenehana Dacromet e ka poʻe ʻAmelika a he hana hoʻoheheʻe metala e like me ka electro-galvanizing.

ʻO ka uhi ʻana o Dacromet he hiʻohiʻona hina hina hina a loaʻa iā 80% nā ʻāpana zinc lahilahi i ka uhi.ʻO ka pepa alumini, ʻo ke koena he chromate, he hana maikaʻi loa, e like me ke kūpaʻa corrosion ikaika: 7 a 10 mau manawa kiʻekiʻe ma mua o ka electrogalvanizing;anaerobic palupalu;kūpono loa no nā ʻāpana ikaika kiʻekiʻe, e like me ka ʻenehana subway ʻO nā bolts ikaika kiʻekiʻe;pale wela kiʻekiʻe;wela-palena wela 300 °C.

Eia kekahi, loaʻa iā ia nā pōmaikaʻi o ka permeability kiʻekiʻe, ka hoʻopili kiʻekiʻe, ka hoʻohaʻahaʻa friction kiʻekiʻe, ke kū kūʻē o ka wā, ke kūpaʻa kemika kiʻekiʻe a ʻaʻohe pollution kaiapuni.

Ma nā ʻāina ʻoihana, ua hoʻohana ʻia ʻo Dacromet metal surface anti-corrosion technology e like me ke kaʻina hana anti-corrosion no nā kaʻina hana maʻamau e like me ka electroplating, hot dip galvanizing, electroplating cadmium, zinc-based alloy plating, phosphating, etc. hoʻemi nui i ka haumia o ke kaiapuni.

Ma muli o kāna hana maʻalahi, mālama i ka ikehu, a me ka pollution haʻahaʻa o ke kaiapuni, hiki i ka ʻenehana Dacromet ke pale i nā pono o ka zinc electroplating kuʻuna a me nā ʻenehana galvanizing wela e like me ka hydrogen embrittlement.No laila, ua hoʻohana nui ʻia ʻo ia mai ka hiki ʻana mai o nā 1970s, ʻoi aku hoʻi i ka ʻoihana kaʻa i nā ʻāina i kūkulu ʻia e like me ʻAmelika Hui Pū ʻIa a me Iapana, a ua hoʻonui ʻia i ke kūkulu ʻana, ka pūʻali koa, ka hana moku, ke kaʻaahi, ka mana uila, nā mea hana home, ka mahiʻai. nā mīkini, nā mines, nā alahaka, etc.
