Paʻa kila uʻi ʻōwili anuanu Ss400 3mm Pepa kila mānoanoa Hot Dip Galvanized Steel Pepa

Pepa uʻie like me ka hana ʻana a me nā ʻano hana hiki ke hoʻokaʻawale ʻia i nā ʻāpana:

① Paʻa kila hoʻoheheʻe wela. Hoʻokomo ʻia ka ʻili kila i loko o ka pahu zinc i hoʻoheheʻe ʻia i hoʻopaʻa ʻia ka ʻili i kahi kila kila zinc. I kēia manawa, hoʻohana nui ʻia ke kaʻina hana galvanizing e hana ai, ʻo ia hoʻi, ka hoʻomau mau ʻana o ka pā kila i ʻōwili ʻia i ka hoʻoheheʻe ʻana o ka zinc i loko o ka pahu plating e hana i ka pā kila galvanized;

② i hoʻohui ʻia i ka pā kila galvanized. Hana ʻia kēia pā kila ma ka wela wela, akā ma hope koke o ka puka ʻana i waho o ke awāwa, ua wela ia ma kahi o 500 ℃ e hana i kahi kiʻi zinc a me ka hao. Loaʻa i kēia pepa galvanized ka paʻa paʻa a me ka weldability;

③ Pāʻani kila kila. ʻO ka pā kila galvanized i hana ʻia e ka electroplating he hana maikaʻi. Akā, lahilahi ka uhi ʻana, ʻaʻole maikaʻi ke kūpaʻa ʻana i ka corrosion e like me ka pepa galvanized wela;

④ ʻO ka ʻaoʻao hoʻokahi ʻaoʻao a me ka ʻokoʻa ʻelua ʻaoʻao galvanized pā kila. ʻO ka pā kila galvanized ʻaoʻao hoʻokahi, ʻo ia hoʻi, nā huahana galvanized wale nō ma kahi ʻaoʻao. ʻOi aku ka maikaʻi o ka hoʻololi ʻana ma mua o ka pepa galvanized ʻaoʻao ʻelua i ka welding, ka uhi ʻana, ka pale ʻana a me ka hana ʻana. I mea e lanakila ai i nā hemahema o ka ʻaoʻao hoʻokahi me ka ʻole o ka zinc coating, aia kahi ʻāpana galvanized i uhi ʻia me kahi ʻāpana lahilahi o ka zinc ma kēlā ʻaoʻao, ʻo ia hoʻi ʻelua ʻaoʻao galvanized sheet;

⑤ Alloy, pā kila galvanized composite. Hana ʻia ia me ka zinc a me nā metala ʻē aʻe e like me ke aluminika, ke alakaʻi, ka zinc alloy a me ka hoʻopili ʻana o ka pā kila. ʻAʻole maikaʻi ka hana anti-rust maikaʻi o ka pā kila, akā maikaʻi nō hoʻi ka hana uhi;
