Kau ʻia ma 2018-04-25Ua lilo ka ʻoihana hana i mea maʻamau i ko mākou ola a noho i kahi kūlana koʻikoʻi ma ka mākeke.I kēia mau lā, hoʻohana pinepine ʻia ka ʻenehana Dacromet i nā hana hana, ʻaʻole wale ka hopena maikaʻi loa, akā hāʻawi pū kekahi iā mākou i ke kōkua nui i ka hana.
ʻAʻole hiki ke hoʻokaʻawale ʻia ka noi o ka ʻenehana Dacromet mai ka hopena Dacromet.Aia kekahi mau kiko'ī e pili ana i nā waiwai o ka solution Dacromet!
Loaʻa i ka ʻenehana Dacromet nā mea maikaʻi aʻe i hoʻohālikelike ʻia me ka ʻenehana electrogalvanizing a me ka ʻenehana galvanizing wela:
1. Kūleʻa maikaʻi i ka corrosion
ʻO ka pale electrochemical o ka zinc, ka hopena pale o ka zinc a me nā ʻāpana alumini a me ka hopena hoʻoponopono ponoʻī o ka chromate e hana i ka uhi Dacromet i kūpaʻa loa i ka corrosion.Ke ho'āʻoʻia ka uhiʻana o Dacromet i kahi ho'āʻo paʻakai paʻakai kūʻokoʻa, pono ia ma kahi o 100 mau hola e hoʻopau i ka uhi 1 um, 7-10 mau manawaʻoi aʻe o ka corrosion ma mua o ka hana galvanizing kuʻuna, aʻoi aku ma mua o 1000 mau hola no ka ho'āʻoʻana i ka paʻakai paʻakai. ʻoi aku ka kiʻekiʻe, ʻo ia ka galvanized a ʻaʻole hiki ke loaʻa ka zinc Hot-dip.
2. Kūleʻa wela maikaʻi
No ka mea, ʻaʻole i loaʻa i nā polymers chromic acid Dacromet-coated ka wai o ka crystallization a me ke kiʻekiʻe o ka helu heheʻe o ka pepa alumini / zinc, ʻoi aku ka maikaʻi o ka pale ʻana i ka corrosion kiʻekiʻe.
