Ka hoʻokaʻawale ʻana o ka pepa galvanized e like me ka hana a me nā ʻano hana
① Pepa kila puʻupaʻa wela. Hoʻokomo ʻia ka pā kila lahilahi i loko o ka ʻauʻau zinc i hoʻoheheʻe ʻia e hoʻopili i kona ʻili i kahi papa zinc. I kēia manawa, hana nui ʻia e ke kaʻina galvanizing mau, ʻo ia hoʻi, hoʻomau mau ʻia ka pā kila i ʻōwili ʻia i loko o ka ʻauʻau hoʻoheheʻe zinc e hana i ka pā kila galvanized;
2 Alloyed galvanized kila pepa. Hana ʻia kēia ʻano pā kila ma ke ʻano wela wela, akā ua wela ia ma kahi o 500 ℃ ma hope koke o ka puka ʻana i waho o ka pahu, no laila e hoʻopili ʻia ai ka zinc a me ka hao. ʻO ka pepa galvanized i hoʻopili maikaʻi i ka uhi a me ka weldability.
③ Pepa kila electrogalvanized. ʻO ka pepa kila galvanized i hana ʻia e ke ʻano electroplating he hana maikaʻi. Eia nō naʻe, ʻoi aku ka lahilahi o ka uhi ʻana a ʻaʻole maikaʻi kona kūpaʻa ʻana i ka corrosion e like me ka pale wela wela.
④ ʻO ka pā kila hoʻokahi ʻaoʻao a me ka pā kila ʻokoʻa ʻelua ʻaoʻao. ʻO ka pā kila galvanized ʻaoʻao hoʻokahi, ʻo ia hoʻi, nā huahana i hoʻopaʻa ʻia ma kekahi ʻaoʻao wale nō. I ka ʻōlelo o ka welding, coating, antirust treatment and processing, ʻoi aku ka maikaʻi o ka reactivity ma mua o ka pepa galvanized ʻaoʻao ʻelua. I mea e lanakila ai i ka hemahema o ka uncoated ma kekahi ʻaoʻao, aia kekahi ʻano galvanized sheet i uhi ʻia me ka ʻāpana lahilahi o ka zinc ma kēlā ʻaoʻao, ʻo ia hoʻi, ʻelua ʻaoʻao galvanized sheet.
⑤ Alloy a me ka hui galvanized pā kila. He pā kila ia i hana ʻia me ka zinc a me nā metala ʻē aʻe e like me ke kēpau, zinc, a me ka hoʻohui pū ʻana. ʻAʻole maikaʻi ka hana anti-rust maikaʻi o kēia ʻano pā kila, akā maikaʻi nō hoʻi ka hana ʻana i ka uhi; Ma waho aʻe o nā ʻano ʻelima i luna aʻe, aia nō hoʻi ka pā kila galvanized kala, paʻi ʻia a hoʻopaʻa ʻia i ke kila kila, a me ka polyvinyl chloride laminated galvanized steel plate. Eia nō naʻe, ʻo ka mea maʻamau i hoʻohana ʻia ʻo ia ka wela-dip galvanized sheet.
