ʻEkolu mau ʻokoʻa ma waena o ka pā kila kala / pā kila / pā pā

I nā makahiki i hala iho nei, ua hoʻomohala ʻia ka hoʻohana ʻana i nā papa kila i hoʻomaʻamaʻa ʻia. Ua hoʻolauna ʻo Baosteel i kahi ʻenehana hana hoʻomau electro-galvanized hou a holomua, hiki iā ia ke hana i nā pā kila electro-galvanized surface-treated steel me ke kiʻekiʻe a me ka hana maikaʻi loa.

Hoʻohana nui ʻia kēia mau pale kila electro-galvanized surface-treated ma nā ʻano like ʻole e like me nā lako hale, nā lako kila, nā lako keʻena, nā kaʻa, a me nā mea kūkulu hale.

ʻElua ʻano o nā pā kila kala. ʻO kekahi ʻo ka galvanizing wela a laila hoʻoheheʻe kala, a ʻo kekahi he galvanizing wela a laila hoʻopuʻi. ʻO nā pā kila kala a me nā galvanizing wela nā mea hana anti-corrosion. Hoʻopili ʻia nā pā kila a hoʻopaʻa ʻia. E kāpīpī i ka pauka waho

ʻAʻole wale ka hopena anti-corrosion maikaʻi, akā he mau kala nani nō hoʻi. He anti-corrosion wale nō nā lau wela wela a ʻaʻohe hopena hoʻonaninani.

He ʻokoʻa nā mea ʻelua. ʻO ka pā alumini he pā anu me kahi papa alumini ma ka ʻili, e like me ka pā galvanized. ʻO ka pā alumini-zinc he pā me kahi papa o ka alumini-zinc antioxidant layer ma luna o ka ʻili a me kahi kumu hoʻohālike (he ʻano like ke ʻano me kahi pā galvanized). pattern), Loaʻa iā ia kahi hopena hoʻonaninani a uhi pinepine ʻia me kahi kiʻi pale. ʻOkoʻa nā waiwai anti-corrosion ma muli o ke kumukūʻai. ʻOi aku ke kumukūʻai o ka pā zinc bi-aluminum.

Aia ka ʻokoʻa ma waena o lākou i ka helehelena:

Hoʻokaʻawale ʻia ka Galvanizing i nā pua ʻole a me nā pua;

He pua ka Galvalume, he mau kala kūikawā i hana ʻia e ka alumini-zinc alloy:

ʻO nā papa kila kala kala

ʻO ka ʻokoʻa ma waena o ka pā kila kala, ka pā galvanized a me ka pā galvanized:

ʻO ka pā hao: pili i kahi pā kila me kahi papa zinc ma ka ʻili. ʻO Zinc a me 2% silikoni paʻa i ka wela kiʻekiʻe o 600°C* Paʻa kila kala: pili i ka pā kila i uhi ʻia. ʻO ka pā kila i hoʻopaʻa ʻia ke kala he ʻano pā kila me ka hoʻopili organik. Loaʻa iā ia ke kūpaʻa corrosion maikaʻi, ke kala ʻulaʻula, ka helehelena nani a me ke ʻano hana. He maʻalahi a loaʻa ka ikaika kumu o ka pā kila akā haʻahaʻa ke kumu kūʻai.
