ʻO ke koʻikoʻi o ka hoʻopaʻa ʻana wela o pepa galvanized ma muli o ka hoʻomaikaʻi maikaʻi ʻia ʻana o ke kūpaʻa ʻino o ke kila ʻōwili wela ma hope o ka uhi ʻia ʻana o ka ʻili o ka galvanizing wela wela, hiki ke mālama i nā mea maka a me nā kumuwaiwai a hāʻawi i ka pāʻani piha i nā pono waiwai maikaʻi a me nā pono kūlohelohe kūlohelohe.
ʻO ke kī i ka maikaʻi o ka mālama ʻana o ka papa galvanizing wela o ka pepa galvanized no ke kila ʻōwili wela e like me kēia:
(1) i ka wā e paʻa ai ka papa kila mānoanoa, ʻo ka zinc corrosion wale nō, no ka mea, ʻoi aku ka maikaʻi o ka mālama ʻana o ka zinc corrosion, no laila ua lohi loa ka corrosion rate, ʻo ke ola lawelawe he 15-30 mau manawa o ka pā kila galvanized.
(2) ʻO ke kūlana maʻamau ka pepa galvanized i ka hana ʻana a me ka hana ʻana, hoʻokomo ʻana, noiʻi, nā ʻili o ka ʻili, a i ʻole nā kumu ʻē aʻe i hoʻopōʻino ʻia ka papa ma lalo o ka ʻāpana, ke kila ʻōwili wela i hōʻike ʻia mai ka ʻeha i loko o ke kaiapuni kūlohelohe, inā ʻo nā kemika. ʻO nā mea metala ʻole, e ʻoki ʻia nā poloka i hōʻike ʻia, akā ʻo ka mālama ʻana i nā ʻano o ke kila i ʻōwili ʻia ʻokoʻa, e hoʻolōʻihi i ka helu etching, ma kēia ʻano ʻo ka zinc i loko o ka uhi a me ka hao i loko o ke kila ʻōwili wela e lilo i galvanic. pūnaewele i loko o ka pulu a me ke anuanu kaiapuni, no ka mea, o ka maʻamau electrode hiki o ka zinc wale nō -1.05V, emi ma lalo o -0.036V o ka hao, pela zinc e like me ka anodic oxidation e ka ea oxidation, a me ka hao e like me ka maikaʻiʻole papa e loaa ka malama. No ka mea he kiʻekiʻe kiʻekiʻe nā huahana ma hope o ka zinc, lohi ka manawa o ka pane ʻana, ʻo ia hoʻi, ʻoi aku ka maikaʻi o ka pale ʻana i ka corrosion. Kapa ʻia kēia ʻano hana pale ʻana i ka corrosion resistance.
