ʻO ka Galvanizing e pili ana i ka ʻenehana lapaʻau ili o ka hoʻopaʻa ʻana i kahi papa zinc ma ka ʻili o ka metala, ka hao a i ʻole nā mea ʻē aʻe no ke kumu o ka nani a me ka pale ʻana.
Hiki ke hoʻoheheʻe ʻia ka Zinc i nā waikawa a me ka alkali, no laila ua kapa ʻia ʻo ia me ka amphoteric metal. Hoʻololi liʻiliʻi ʻo Zinc i ka ea maloʻo. ʻilihune ka pale ʻana, ʻoi aku ka nui o ka wela a me ka haʻahaʻa kiʻekiʻe e loaʻa ana i ka lewa waikawa organik, maʻalahi ka hoʻopili ʻana o ka zinc.No ka matrix kila, pili ka zinc coating i ka anodic coating, i hoʻohana nui ʻia e pale i ka corrosion o ke kila.ʻO kāna hana palekana he pilina maikaʻi loa me ka mānoanoa o ka uhi.
ʻO ke kumumanaʻo ka wikiwiki o ka oxidize i ka ʻili o ka hao a me nā huahana kila e hana i kahi ʻāpana pale kiʻi ʻoniʻoni ʻoniʻoni. ʻAʻole maikaʻi ke kila kalapona haʻahaʻa. ʻOi aku ka maikaʻi o ka ʻeleʻele ʻana i ke kila A3 me ka alkali. Ua māhele ʻia ka ʻeleʻele ʻeleʻele, loaʻa hou ka ʻeleʻele a ʻelua ʻeleʻele ʻokoʻa. laula, mai ma kahi o 135 degere Celsius a hiki i 155 degere Celsius, a loaʻa iā ʻoe kahi ili maikaʻi, akā e lawe i kekahi manawa. Ma ka hana pono, pono e uku ʻia ka maikaʻi o ka ʻōpala a me ka ʻaila ma mua o ka blackening o ka workpiece, a me ka ʻO ka hoʻokomo ʻana i ka aila passivation ma hope o ka ʻeleʻele.ion or acid oxidation.ʻO ke kaʻina hana o ka hana ʻana i kahi kiʻiʻoniʻoni oxide ma ka ʻili metala e pale ai i ka corrosion ua kapa ʻia ʻo "bluing". ʻO ka ʻili o loko he ferrous oxide.
Hoʻohana maʻamau ʻia nā bolts kiʻekiʻe - ikaika i nā hui koʻikoʻi, e pili ana i ka ʻoi aku ka nui o ka ʻāʻī a me ka ʻā. galvanizing bolts.Hydrogen embrittlement ka mea maʻamau i ka lohi ʻana i ka haʻi. ʻaʻole pili me nā mea ʻino.
