No ka hoʻohana piha ʻana i kahi huahana, pono e ʻike mua kekahi i ia mea, a ʻaʻole ʻokoʻa nā ʻōwili i uhi ʻia. A laila, e hoʻolauna mākou iā mākou iho i nā ʻōwili kala i uhi ʻia.
ʻO ka mea mua, pono mākou e ʻike he aha ka papa i uhi ʻia?

ʻO ke kala kila i uhi ʻia me ka hoʻohana ʻana i ke kaula hao wela wela e like me ka substrate ʻaʻole wale he papa zinc no ka pale ʻana, akā loaʻa nō hoʻi kahi uhi kūlohelohe ma ka papa zinc no ka uhi ʻana a me ka pale ʻana, e pale ana i ke kaula kila mai ka ʻōpala. ʻO kona ola lawelawe ma kahi o 1.5 manawa ʻoi aku ka lōʻihi ma mua o ke kaula hao galvanized. ʻO ka lua, pono mākou e hoʻomaopopo mua i nā kumu o nā ʻōwili i uhi ʻia? He māmā nā ʻōwili kala i hoʻopaʻa ʻia, ʻoluʻolu maikaʻi, a maikaʻi ke kūpaʻa ʻana i ka corrosion. Hiki ke hoʻoponopono pololei ʻia a loaʻa ma nā ʻano keʻokeʻo hina keʻokeʻo, uliuli moana, a me ka ʻulaʻula brick. Hoʻohana nui ʻia lākou i ka hoʻolaha, ke kūkulu ʻana, nā mea hana hale, nā lako, a me nā ʻoihana kaʻa.
ʻO ka uhi i hoʻohana ʻia no nā ʻōwili kala e koho i nā resins kūpono e like me nā kaiapuni hoʻohana like ʻole, e like me ka polyester silicon modified polyester, polyvinyl chloride plastic sol, polyvinylidene chloride, etc. Hiki i nā mea hoʻohana ke koho e like me kā lākou makemake. A laila, pono ʻoe e ʻike i ke ʻano o ka uhi ʻana:
ʻO ke ʻano hoʻolālā hoʻouhi V
2/1: E hoʻopili i ʻelua ma ka ʻaoʻao luna, hoʻokahi ma ka ʻaoʻao haʻahaʻa, a e hoʻomoʻa i ʻelua manawa.
2/1M: E hoʻopili i ʻelua ma ka ʻaoʻao o luna a me lalo, a hoʻomoʻa i hoʻokahi manawa.
2/2: E hoʻopili i ʻelua ma ka ʻaoʻao o luna a me lalo, a hoʻomoʻa ʻelua.
ʻO ka hoʻohana ʻana i nā ʻano like ʻole o ka uhi ʻana:
2/1: He ʻilihune ka pale ʻana i ka corrosion a me ke kūʻē ʻana o ka pena kua hoʻokahi, akā maikaʻi kona adhesion a hoʻohana nui ʻia i nā panela sandwich;
2/1M: He kūpaʻa maikaʻi ka peʻa hope, ke kū ʻana o ka ʻōpala, a me ka hoʻoponopono ʻana, me ka hoʻopili maikaʻi ʻana, kūpono no nā panela profiled one-layer a me nā panela sandwich.
2/2: ʻO ka pena kua ʻelua ʻāpana he kūpaʻa maikaʻi i ka corrosion, ka pale ʻana, a me ka hoʻoponopono ʻana, a hoʻohana nui ʻia no nā panela profiled one-layer. Eia nō naʻe, ʻilihune kona adhesion a ʻaʻole kūpono ia no nā panela sandwich.

He aha nā ʻano o nā substrate i uhi ʻia i ka kala?
ʻO ka substrate galvanized wela
ʻO ka huahana i loaʻa ma ka hoʻopili ʻana i ka hoʻopili ʻana i ka mea hoʻopulapula ma luna o ka ʻili kila wela-wela ʻo ia ka pepa i uhi ʻia i ka waihoʻoluʻu wela. ʻAʻole wale ka hopena pale o ka zinc, akā ʻo ka uhi ʻana i ka ʻili i ka pale ʻana a me ka pale ʻana i ka ʻōpala, me ka lōʻihi o ke ola ma mua o ka wela wela. He 180g/m2 ka maʻiʻo zinc o nā substrate galvanized wela wela (ʻaoʻao pālua), a ʻo 275g/m2 ka nui o ka zinc o nā substrates wela wela no ka hoʻohana ʻana i waho i nā hale.
Pāpaʻa zinc alumini wela wela
Hoʻohana ʻia ka pāpaʻa kila zinc alumini wela wela (55% Al Zn) ma ke ʻano he substrate i uhi ʻia, maʻamau me ka ʻike alumini zinc o 150g/㎡ (ʻaoʻao ʻelua). ʻO ke kūpaʻa ʻana o ka pepa zinc alumini wela he 2-5 mau manawa ma mua o ka pepa galvanized hot-dip. ʻO ka hoʻohana mau ʻana a i ʻole ka hoʻohana ʻana i nā mahana a hiki i 490 ℃ ʻaʻole ia e hopena i ka hoʻoneʻe ʻana a i ʻole ke kūkulu ʻia ʻana o nā unahi oxide. ʻO ka hiki ke hoʻohālikelike i ka wela a me ka māmā he pālua ia o ka pā kila wela, a ʻo ka reflectivity ʻoi aku ma mua o 0.75 he mea hale kūpono no ka mālama ʻana i ka ikehu.
Electroplated galvanized substrate
ʻO ka huahana i loaʻa ma ka hoʻohana ʻana i ka pepa galvanized electroplated e like me ka substrate a me ka hoʻomoʻa ʻana iā ia me ka hoʻopili organik ʻo ia ka pepa i uhi ʻia i ke kala galvanized electroplated. Ma muli o ka lahilahi zinc layer o electroplated galvanized sheet, ʻo ka zinc content maʻamau he 20/20g / m2, no laila ʻaʻole kūpono kēia huahana no ka hoʻohana ʻana i waho i ka hana ʻana i nā pā, nā hale, a me nā mea ʻē aʻe. hiki ke hoʻohana nui ʻia no nā lako hale, nā ʻōnaehana leo, nā lako kila, nā mea hoʻonaninani i loko, a me nā mea ʻē aʻe. Inā makemake ʻoe, e hele mai e nīnau iā mākou!
