E pili ana i ke kala i uhi ʻia i ke kila wili / prepainted steel coil structure

Hoʻokumu ʻia ka coil i uhi ʻia me ka lole luna, primer, uhi, substrate a me ka pena kua.

Hoʻopau pena:pale i ka lā, pale i ka pōʻino ultraviolet i ka uhi;Ke hiki ka hopena i ka mānoanoa i kuhikuhi ʻia, hiki iā ia ke hana i kahi kiʻiʻoniʻoni pale paʻa, e hōʻemi ana i ka permeability o ka wai a me ka oxygen.

Kumuhana:He mea maikaʻi ia e hoʻoikaika i ka hoʻopili ʻana o ka substrate, no laila ʻaʻole maʻalahi ka desorption o ka pena ma hope o ka hoʻopiha ʻia ʻana o ke kiʻiʻoniʻoni me ka wai, a e hoʻomaikaʻi hoʻi ia i ka pale ʻana i ka corrosion, no ka mea, aia ka primer i nā puaʻa corrosion inhibitors, e like me ka chromate pigments, no laila ua hoʻololi ʻia ka anode a hoʻomaikaʻi ʻia ke kūpaʻa corrosion.

ka uhi:maʻamau galvanized a i ʻole alumini zinc plating, ʻo kēia ʻāpana o ke ola lawelawe o ka huahana ka hopena nui loa, ʻoi aku ka mānoanoa o ka uhi ʻana, ʻoi aku ka maikaʻi o ka pale ʻana i ka corrosion.

Pāpala:ʻO ka mea maʻamau no ka pā anu i ʻōwili ʻia, ʻokoʻa ka ikaika e hoʻoholo i nā waiwai mechanical o ka pā i uhi ʻia i ka waihoʻoluʻu hiki ke hoʻomanawanui.

Pena kua hope:ʻO ka hana ka pale ʻana i ka corrosion o ka pā kila mai loko mai, ma ke ʻano he ʻelua papa o ka hale (2/1M a i ʻole 2/2, primer + pena hope), inā pono e hoʻopaʻa ʻia ke kua, ʻōlelo ʻia e hoʻohana i kahi papa hoʻokahi. (2/1).

ʻO ke kaʻina hana ʻinoʻino i uhi ʻia i ke kala.

ʻO ka uhi ʻana, ka uhi kala, ka pauka, ka ʻūhā ʻūhā, keʻokeʻo/ʻulaʻula — – — – — ma ka laina ʻoki ʻili i ka ʻōpala – ʻoki – uhi ʻia ma waho — – — – — ʻāpana nui o ka ʻōpala, ʻulaʻula kūloko - pā - ʻaʻole hiki ke hoʻoheheʻe ʻia ka ʻōpala perforation.

Hōʻike ʻia ke kaʻina hana hāʻule o ka pā kila i uhi ʻia ma ke kiʻi ma luna.ʻO ka hāʻule ʻole o ka uhi ʻana, ka hāʻule ʻana o ka uhi a me ka perforation o ka pā kila nā kaʻina hana corrosion.No laila, ʻo ka hoʻonui ʻana i ka mānoanoa o ka uhi ʻana a me ka hoʻohana ʻana i ka uhi ʻana a me ka corrosion resistant coating ʻo ia ke ala maikaʻi loa e pale ai i ka hiki ʻole o ka corrosion o ka pā kila i uhi ʻia.
