ʻO ka coil i uhi ʻia ka waihoʻoluʻu he pā galvanized wela, wela galvanized alumini zinc plate, galvanized plate a me nā substrates ʻē aʻe, ka hoʻomaʻamaʻa ʻana o ka ʻili (kemika degreasing a me ka hoʻololi hoʻololi ʻana i ka lāʻau), ma luna o ka ʻili i uhi ʻia me kahi papa a i ʻole kekahi mau papa o ka uhi kūlohelohe, a laila ma hope o ka kuke ʻana. nā huahana ho'ōla.No ka mea i uhi ʻia me nā ʻano kala like ʻole o ka peʻa kala kala kila kila i kapa ʻia, i kapa ʻia ʻo coil coated color.
Nā hiʻohiʻona
Pāpaʻa galvanized: uhi lahilahi, pale ʻino e like me ka substrate galvanized wela;
Hot-dip galvanized substrate: ua hoʻokomo ʻia ka pā kila lahilahi i loko o ka pahu zinc i hoʻoheheʻe ʻia, i hiki ai i kona hoʻopili ʻana i kahi papa o ka zinc, ua loaʻa i kēia pā galvanized ka paʻa paʻa a me ka weldability.
Pāpaʻi zinc alumini wela:
Hoʻopili ʻia ka huahana me 55% Al-Zn, e hāʻawi ana i ke kūpaʻa corrosion maikaʻi loa, a ʻoi aku kona ola lawelawe ma mua o ʻehā mau manawa o ke kila galvanized maʻamau.ʻO ia ke pani ʻana i ka pepa galvanized.
Nā hiʻohiʻona huahana:
(1) Loaʻa i ka lōʻihi maikaʻi, ka pale ʻana i ka corrosion a me ke kila galvanized i hoʻohālikelike ʻia me ke ola lōʻihi;
(2) Me ke kūpaʻa wela maikaʻi, ke hoʻohālikelike ʻia me ka pā kila galvanized, ʻaʻole maʻalahi ke hoʻololi i ke kala i ke kiʻekiʻe wela;
(3) Loaʻa iā ia ka reflectivity thermal maikaʻi;
(4) loaʻa iā ia ka hana like ʻana a me ka pipi ʻana i nā waiwai i ka pā kila galvanized;
(5) He hana kuʻihao maikaʻi.
(6) Me ka hoʻokō maikaʻi-i-kumuki ratio, hana mau a me ka uku hoʻokūkū.No laila, inā paha ua hoʻohana nui ʻia nā mea hoʻolālā, nā ʻenekinia a i ʻole nā mea hana i nā hale ʻoihana, nā hale kila a me nā hale kīwila, e like me: nā puka hale kaʻa, ka ʻauwai a me ka hale.

ʻO kā Mill maʻamau e lawe aku i ke kai kūpono e hoʻopili ai:
ʻO ka pepa wai a me ka kiʻi ʻoniʻoni a me ka pale kila pale a me ka pā pale o loko a me ka ʻaoʻao, ka ʻaoʻao a me waho a me ke apo anawaena o loko a me ke kaula metala strapping & circumferential bands i ke kila & galvanized metal fluted apo ma loko a i ʻole hoʻopili kūikawā e like me kou makemake.

ʻO ke kala i uhi ʻia he māmā ke kaumaha, nani a maikaʻi hoʻi ke kūpaʻa corrosion, a hiki ke hana pololei ʻia, ua māhele ʻia ke kala i ka hina, uliuli, ʻulaʻula ʻulaʻula, hoʻohana nui ʻia i ka hoʻolaha ʻana, ke kūkulu ʻana, nā mea hana hale, nā mea uila, nā ʻoihana lako a me nā ʻoihana halihali. .
