ʻO ke kiʻekiʻe o ka chromium hoʻoheheʻe ʻia i ka hao bimetal aahu -paipu kūpaʻa
ʻO ke kiʻekiʻe chromium hoʻolei ʻia i ka hao bimetal ʻaʻahu -pahu kūʻokoʻa he ʻano o ka paipu kūpaʻa kū hoʻokahi -ka hale, i haku ʻia me nā mea papa waho a me nā mea papa o loko. He maikaʻi ke kūʻē corrosion o ka ʻili o waho, a ʻo ka mea ʻāpana o loko he kūpaʻa kiʻekiʻe loa. Hiki i kēia hui pū ʻana o nā mea waiwai ke hoʻopau pono i ka pale ʻana i ka ʻaʻahu a me nā pilikia kūʻē corrosion i kekahi mau kaiapuni kūikawā.
Hoʻokomo i nā mea nui
ʻAi loko -palena ʻaʻahu
ʻO nā mea nui o ka ʻaʻahu o loko -kūʻokoʻa ʻo ia ka chromium kiʻekiʻe i hoʻolei ʻia i ka hao, ke kiʻekiʻe chromium keʻokeʻo hao a me ka chromium kiʻekiʻe, a me nā mea ʻē aʻe.
ʻAi kuʻekuʻe -waho
ʻO nā mea nui o ka ʻili ʻino -kūʻokoʻa o waho, he kila kila, nickel-alloy a me steel-plastic composite material, etc. He maikaʻi ko lākou pale ʻana i ka corrosion a me ka ʻakika a me ka alkali, a hiki ke hoʻohana ʻia no ka manawa lōʻihi i ka pōʻino.
