Inā ma muli o ka hana ʻino a i ʻole ka maikaʻi ʻole o ka hoʻokele ʻana o nā mea hoʻoheheʻe wela, hiki ke haʻalele ʻia kēlā mau hemahema. Ma keʻano laulā, aia kekahi mau pilikia maʻamau.
1. Hōʻike ʻia nā ʻāpana zinc galvanized ma luna o ka ʻili, ʻo ia hoʻi, ʻaʻole poni ʻia kēlā mau mea liʻiliʻi liʻiliʻi, a ʻoi aku ka nui o ia mau mea liʻiliʻi e pili ana i ka helehelena, akā pili pū i ka hoʻohana. ʻO ke kumu o ka hoʻokumu ʻana o ia mau ʻāpana no ka mea ʻoi aku ka nui o ka lalo o ka mīkini galvanizing dross agitated float adhered galvanized sheet surface temperature kiʻekiʻe loa ma laila no ka mea e lana ana ka hana ʻana o ia slag lalo, ʻo ia hoʻi, ʻo ka zinc solution ka nui o ka alumini, zinc a aluminika i loaʻa ka pilina maikaʻi, pēlā pū, pili i ka ʻili pepa galvanized. ʻO ka hoʻopau ʻana i nā ʻāpana zinc pono wale nō ka lāʻau lapaʻau i hiki ke hana ʻia, no ka laʻana, hana pinepine i ka slag lalo, mālama i ka hoʻomaʻemaʻe ʻana i ke kaiapuni galvanized; ʻAʻole kiʻekiʻe loa ka mahana ʻauʻau galvanizing, mālama ʻia ma 440 ℃ ~ 450 ℃ kūpono; ʻAʻole kiʻekiʻe ka ʻike o ka aluminika i loko o ka zinc wai, e noho ana ma kahi o 0.1% kūpono, E hoʻomaopopo hoʻi i ka lōʻihi o ka waiwai e hoʻonui ai i ka oxidation, a me nā mea ʻē aʻe i ka pōkole, ʻoiai ka lōʻihi o ka hana ʻana o nā ʻāpana zinc, a hiki ke hoʻopau ʻia.

2. Galvanized kila ili e hana i ka mānoanoa lihi, 'o ia hoʻi, o ka lihi ma mua o ka waena o ka mānoanoa papa o ka zinc, lilo ia i mānoanoa lihi defects,ʻaʻole conducive e wehe coiling.

3. Inā e hoʻopaʻa ʻia kahi ʻāpana pahi ea i nā hōʻailona pahi ea, e koi i kahi mea hoʻomaʻemaʻe kūikawā e hoʻomaʻemaʻe.

4. ʻO ka uhi zinc hina ka hopena i hui pū ʻia me ka hao a me ka zinc alloy.

Eia kekahi, aia kekahi mau hemahema o ka ʻili, e like me nā ʻoki ʻana i ka pahi ea, nā kuhi zinc, ka ʻili o ka pūpū, nā iwi ʻaoʻao, a me nā mea ʻē aʻe, e koi ana i nā mea hana i ke kaʻina hana i nā kaʻina hana koʻikoʻi, ka hana koʻikoʻi e hana i nā huahana ʻoi aku ka maikaʻi.
