ʻO Kina Peʻa Galvanized Zinc Sheet/Coil

Manaʻo kumu:
Ma ka ʻāpana hoʻomau, hoʻohana ʻia ke kila ʻōwili anu a me ke kila galvanized (electro-galvanized a me hot-dip galvanized) ma ke ʻano he substrates, a ma hope o ka hoʻomaʻamaʻa ʻana o ka ʻili (degreasing a me ka lāʻau kemika), hoʻohana ʻia ke ʻano o ka uhi ʻana.

Hoʻopili ʻia hoʻokahi a ʻoi aʻe paha o ka pena wai, a ua kapa ʻia ka pepa i loaʻa ma ka kuke ʻana a me ka hoʻoluʻu ʻana he ʻāpana kila i uhi ʻia.

No ka mea hiki i ka uhi ke loaʻa i nā ʻano kala like ʻole, he mea maʻamau ke kau ʻana i ke kila i uhi ʻia.

Ua kapa ʻia nā papa i nā papa kila i uhi ʻia i ka kala. A no ka lawe ʻia ʻana o ka uhi ʻana ma mua o ka hoʻokumu ʻia ʻana o ka pā kila, ua kapa ʻia ʻo ia he pā kila pre-coated ma nā ʻāina ʻē.

Kaʻina hana:

Hoʻokumu ʻia nā ʻāpana kila i hoʻopaʻa ʻia i ke kala ma luna o nā pale kila i hoʻoheheʻe ʻia a me nā pale kila galvanized. Ma hope o ka hoʻomaʻamaʻa mua ʻana o ka ʻili (degreasing, hoʻomaʻemaʻe, hoʻololi ʻana i nā kemika), hoʻohana ʻia nā uhi ma ke ʻano hoʻomau.

ʻO ke kaʻina hana nui o ke kaʻina hana ʻelua-pani a me ʻelua-bake mau kala hoʻomau kaʻina kaʻina hana: uncoiling → pretreatment → coating → baking → post-processing → coiling.

ʻO ka pā kila i uhi ʻia he māmā ke kaumaha, nani ke ʻano a me ke kūpaʻa corrosion maikaʻi, a hiki ke hana pololei ʻia.
Hāʻawi ia i kahi ʻano mea maka hou, i loaʻa nā hopena maikaʻi e like me ka hoʻololi ʻana i ka lāʻau me ke kila, ka hana kūpono,

mālama i ka ikehu, a me ka pale ʻana i ka pollution. ʻO ka uhi kala me ka hoʻohana ʻana i ka pepa kila galvanized ma ke ʻano he substrate

Ma waho aʻe o ka pale ʻana i ka zinc, ʻo ka uhi kūlohelohe ma ka papa zinc ke kuleana o ka uhi ʻana a me ke kaʻawale, hiki

pale i ka pā kila mai ka ʻāʻī ʻana, a ʻoi aku ka lōʻihi o kona ola lawelawe ma mua o ka pā kila galvanized.

Wahi a ka hoʻolauna, ʻo 50% ka lōʻihi o ke ola o ka pā i uhi ʻia ma mua o ke ola o ka pā kila.
