pepa kila i uhi kala ʻia

Hoʻohana ʻia ka pepa kila galvanized e like me ke kumu kumu.Ma waho aʻe o ka pale ʻana i ka zinc, ʻo ka uhi kūlohelohe ma ka papa zinc e pāʻani pū kekahi i ka uhi a me ka hoʻokaʻawale ʻana, hiki ke pale i ka pale kila mai ka ʻōpala a ʻoi aku ka lōʻihi o ka lawelawe ʻana ma mua o ka pale kila.Ua ʻōlelo ʻia ʻo 50% ka lōʻihi o ke ola lawelawe o ka pale kila i uhi ʻia ma mua o ka galvanized steel sheet.ʻO nā hale a i ʻole nā ​​hale hana i hana ʻia me nā ʻāpana kila i uhi ʻia i ka waihoʻoluʻu e lōʻihi ke ola ke holoi ʻia e ka ua, inā ʻaʻole e hoʻohana ʻia lākou e ke kinoea sulfur dioxide, ka paʻakai a me ka lepo.No laila, i ka hoʻolālā, inā nui ka pali o ka hale, ʻaʻole paha e hōʻiliʻili i ka lepo e like me ka lepo, a lōʻihi ke ola lawelawe.No kēlā mau wahi a i ʻole nā ​​ʻāpana i holoi pinepine ʻole ʻia e ka ua, pono e holoi mau ʻia me ka wai.

Eia nō naʻe, ʻokoʻa loa ke ola lawelawe o nā papa i uhi ʻia me ka nui o ka zinc plating, nā mea hoʻonaninani like a me ka mānoanoa o ka uhi like ʻole e ʻokoʻa loa i nā wahi like ʻole a me nā wahi hoʻohana like ʻole.No ka laʻana, ma nā wahi ʻoihana a i ʻole nā ​​​​wahi kahakai, ma muli o ka hopena o ke kinoea sulfur dioxide a i ʻole ka paʻakai i ka lewa, piʻi ka nui o ka corrosion a pili ke ola lawelawe.I ka wā ua, inā lōʻihi ka uhi ʻana i ka ua a i ʻole ka nui o ka ʻokoʻa o ka mahana ma waena o ke ao a me ka pō, e maʻalahi ka condensation, e ʻino koke ka uhi, a e pōkole ke ola lawelawe.
