Hāʻawi ʻo Dacromet i ka hoʻohālikelike hoʻolauna

Kau ʻia ma 2019-02-22ʻO ka pono o Dacromet
He maikaʻi loa ka pale wela o Dacromet.Ke hoʻohālikelike ʻia i ke kaʻina hana galvanizing maʻamau, ʻaʻole e hoʻopilikia ʻia ʻo Dacromet ma 300 °C, akā e ʻili ke kaʻina hana galvanizing ma kahi o 100 °C.ʻO Dacromet kahi uhi wai.Inā he ʻāpana paʻakikī, e like me nā ʻano like ʻole, nā lua hohonu, nā ʻāpana, ka paia o loko o ka paipu, a me nā mea ʻē aʻe, paʻakikī ke pale me ka galvanizing.He paʻa maikaʻi ko Dacromet me ka substrate metala e hoʻopili maʻalahi i ka uhi Dacromet i ka ʻili o ka ʻāpana.ʻO ka lua, ʻo Dacromet ka maikaʻi o ka weatherability a me ke kūpaʻa kemika.ʻAʻohe hopena o nā mea hoʻoheheʻe organik a me nā mea hoʻomaʻemaʻe i ka pale o ka uhi.Ma ka hoʻokolohua pōʻaiapuni a me ka hoʻokolohua ʻike lewa, he kūʻē maikaʻi loa ia, ʻoiai ma nā wahi kokoke i kahakai a me nā wahi haumia nui, mālama ʻia me ke kaʻina hana Dacromet.ʻOi aku ka liʻiliʻi o nā ʻāpana i ka corrosion a ʻoi aku ka ikaika o ka pale ʻana ma mua o ka galvanizing.
ʻO ka hemahema o Dacromet
Aia kekahi o nā Dacromets i nā ion chromium e pōʻino i ke kaiapuni a me ke kino o ke kanaka, ʻoi aku ka nui o nā ion chromium hexavalent (Cr 6+).Loaʻa i ka Dacromet kahi mahana sintering kiʻekiʻe, kahi manawa lōʻihi a ʻoi aku ka nui o ka ikehu.ʻAʻole kiʻekiʻe ka paʻakikī o ka ʻili o Dacromet, ʻaʻole maikaʻi ke kūpaʻa ʻana, a ʻaʻole kūpono nā huahana i uhi ʻia ʻo Dacromet no ka hoʻopili ʻana a me ka pilina me nā ʻāpana keleawe, magnesium, nickel a me nā ʻāpana kila, no ka mea, e hoʻopiʻi lākou i ka corrosion, e pili ana i nā huahana.ʻO ka ʻili o ka uhi Dacromet he kala hoʻokahi, ʻo ke kālā keʻokeʻo wale nō a me ke kala hina, ʻaʻole kūpono ia no nā pono pilikino o ke kaʻa.Eia nō naʻe, hiki ke loaʻa nā kala like ʻole ma hope o ka mālama ʻana a i ʻole ka uhi ʻana i hui pū ʻia e hoʻomaikaʻi ai i ka hoʻonaninani a me ka hoʻohālikelike ʻana i nā ʻāpana kaʻa.ʻAʻole maikaʻi loa ka conductivity o ka uhi Dacromet, no laila ʻaʻole kūpono ia no nā ʻāpana i hoʻopili ʻia, e like me nā bolts grounding no nā mea uila.E ʻelemakule koke ʻo Dacromet ke ʻike ʻia i ka mālamalama, no laila pono e hana ʻia ke kaʻina hana uhi ʻo Dacromet i loko o ka hale.Inā haʻahaʻa a kiʻekiʻe paha ka mahana baking o Dacromet, e lilo ana ʻo Dacromet i kona hiki ke kūʻē i ka corrosion, a pono e kālua ʻia ʻo Dacromet i ka pae wela kūpono.
