Kau ʻia ma 2018-09-10Aia ka kiʻi ʻoniʻoni Dacromet me ka zinc scaly metala maikaʻi, ka pauka alumini a me ka chromate.He uhi metala hina hina matt i loaʻa ma hope o ka uhi ʻana a me ka kuke ʻana.Ua kapa ʻia ʻo ia ka zinc flake coating.ʻOiai ua like ke ʻano o ka uhi ʻana o Dacromet me kahi papa electrogalvanized kuʻuna, ua loaʻa i ka uhi Dacromet nā mea maikaʻi ʻaʻole hiki ke hoʻohālikelike i nā papa zinc-plated kuʻuna.
1) ʻAʻohe hydrogen brittle.ʻAʻohe waika ka kaʻina hana Dacromet a ʻaʻohe pilikia o ka hydrogen permeation.He kūpono loa ia no nā bolts ikaika kiʻekiʻe a me nā ʻāpana elastic ma hope o ka hoʻōla ʻana i kahi wela kiʻekiʻe.
2) ʻAʻole haumia ka hana.ʻO ke kaʻina hana lapaʻau ʻo Dacromet ʻaʻohe ʻekolu ʻōpala, no laila ʻaʻole ia e hoʻohaumia i ke kaiapuni.
3) Kūleʻa loa i ka corrosion.He lahilahi loa ke kiʻi ʻoniʻoni Dacromet, akā ʻo kona hopena pale i nā ʻāpana kila he 7-10 mau manawa o ka papa zinc electroplated o ka mānoanoa like.ʻO ka uhi ʻana o Dacromet i loaʻa e ka uhi ʻekolu a me ka hoʻomoʻa ʻana ʻekolu i ka pale ʻana i ka paʻakai paʻakai ma mua o 1000h.
4) Ke kūlana kiʻekiʻe a me ka pale wela maikaʻi.Hoʻopili ʻia ke kaʻina hana ʻo Dacromet a i uhi ʻia, ʻaʻohe pilikia o ka plating maikaʻi ʻole a me ka hiki ke plating hohonu ma muli o ke ʻano paʻakikī o ka mea hana, a hiki ke hoʻohana mau ʻia ka uhi ʻana no ka manawa lōʻihi i kahi kaiapuni 250 degere, a me ka corrosion. mālama ʻia ke kūʻē, ʻaʻole pili ka helehelena.
5) Electrochemical corrosion kū'ē i ka zinc-aluminum bimetal.ʻO ka hapa nui o nā papa zinc e hana maikaʻi me ka alumini a i ʻole ke kila kila e hana i nā microbatteries bimetallic maʻamau, a ʻo nā flakes alumini i loko o ka uhi Dacromet e hoʻopau i kēia ʻano.
6) ʻO ka hiki ke recoating ikaika loa.Hiki ke hoʻihoʻi maikaʻi ʻia ka uhi Dacromet a hiki ke kau ʻia i ka pena kiʻekiʻe ma ka ʻili o ka mea hana ma hope o ka hana ʻana.
