Ke kila Galvalume (GL): He aha ia, kahi e hana ai, a pehea e hoʻoholo ai inā kūpono ia nou

Inā ua kūʻai aku ʻoe a puni no ke kila i uhi ʻia, ʻike ʻoe i ka wili. Galvanized (GI), Galvalume (GL), ZAM—ua hoʻolaha ʻia kēlā me kēia ma ke ʻano he pane. A ʻo ka ʻoiaʻiʻo, maikaʻi lākou a pau, no nā kūlana like ʻole. ʻO ka mea nui maoli kahi e hele ai ka mea, pehea ka lōʻihi e pono ai ke kūpaʻa, a me nā mea āu e makemake ai e hoʻolilo. ʻO kēlā ʻōlelo, ua lilo ʻo GL i mea punahele no nā noi he nui o waho a me nā mahana kiʻekiʻe, no ka mea ʻoi aku ka lōʻihi o ke ola ma mua o GI i kēlā mau kūlana me ka ʻole o ka uhaki ʻana i ka panakō.

No laila, he aha ka Galvalume?

He kila ʻōwili anu ia i hoʻoluʻu ʻia i loko o kahi ʻauʻau hoʻoheheʻe ʻia o ka alumini, zinc, a me kahi ʻāpana silicon. Hana ka hui uhi i kahi 55% alumini, 43.4% zinc, a me 1.6% silicon. Hana ka alumini i ka hāpai kaumaha ma ke kūpaʻa ʻana i ka pala—hana ia i kahi papa oxide paʻa e pale ai i ka makū. He ʻokoʻa ke kuleana o ka zinc: he mōhai ia, ʻo ia hoʻi, e pala mua ia inā e kahakaha ʻia ka uhi, e pale ana i ke kila ma lalo. Silicon? Aia kēlā ma laila e hōʻoia i ka hoʻopaʻa pono ʻana o ka uhi i ka metala kumu i ka wā o ke kaʻina hana luʻu. E hoʻohui i nā mea a pau, a loaʻa iā ʻoe kahi huahana e paʻa ana no ka manawa lōʻihi ma mua o ka maʻamau. Ke kila galvanized ma ka hapa nui o nā wahi waho, ʻoiai kahi he mau mea nui ka wela a me ka makū.

ʻŌwili a pepa paha—ʻo wai ka mea āu e pono ai?

Loaʻa ka hapa nui o GL i ʻelua ʻano. ʻO nā wili ka mea a nā mea hana e makemake ai—hoʻokomo lākou i nā mea hana ʻōwili, nā mea paʻi kiʻi, a i ʻole nā ​​laina ʻokiʻoki e hana i nā panela uhi hale, nā ʻauwai, a i ʻole nā ​​​​ʻāpana i hana ʻia. Inā ʻoe e holo nei i kahi laina hana, ʻo nā wili ke ala e hele ai. ʻO nā pepa he mau wili wale nō i ʻoki ʻia i ka lōʻihi, a ʻoi aku lākou no ka hoʻohana pololei—e noʻonoʻo i nā limahana kūkulu e kau ana i nā panela paia a i ʻole nā ​​​​hale kūʻai lako e pono ai ka waihona pālahalaha no ka hana ʻana. Hiki ke kūkākūkā ʻia ka mānoanoa, ka laulā, a me ke kaumaha o ka uhi ʻana, i loko o ke kumu. ʻO ka hapa nui o nā mea hoʻolako, me Ecosteel Source, e hana i nā kikoʻī ASTM A792 a i ʻole EN 10346, akā e hoʻopilikino pū lākou inā koi kāu papahana i kahi mea kikoʻī.

No ke aha e koho ai nā kānaka iā GL ma mua o GI?

ʻO ke kumukūʻai e kūʻē i ka hana, maʻalahi a maʻalahi. ʻOi aku ka liʻiliʻi o ke kumukūʻai o GI ma mua, akā lanakila pinepine ʻo GL ma ke ola lōʻihi i nā kūlana i hōʻike ʻia. Hoʻolohi ka alumini i loko o ka uhi i ka pala ma ke ʻano hiki ʻole i ka zinc wale nō ke hoʻokūkū, ʻoiai ma lalo o ka hōʻike UV a me ka ua. ʻO ia ke kumu e ʻike ai ʻoe iā GL ma nā hale hao āpau, nā paia hale kūʻai, a me nā hale ʻoihana. ʻO ka wela kekahi kumu - kōkua ka nui o ka alumini i ke kila e mālama i kona kūpaʻa i nā mahana kiʻekiʻe, no laila he kūpono maoli ia no nā hale HVAC, nā ʻāpana hoʻopau, a me ka hale hana hale hana i nā aniau wela. Eia kekahi, ʻoi aku ka maʻalahi o ka ʻili a ʻoi aku ka maikaʻi o ke ʻano, he mea nui ia inā e ʻike ʻia ke kila.

Ma hea kahi e hoʻohana maoli ʻia ai ʻo GL?

Ma nā wahi āpau āu e pono ai kahi ʻili paʻa a kūpaʻa i ka wā. ʻO ka uhi ʻana i nā hale a me nā hale kalepa. Nā hale hana ʻoihana a me nā kikowaena hāʻawi. Nā hale mahiʻai a me nā hale papaʻa. Nā ʻāpana HVAC a me nā panela mīkini. I kēia mau lā, ua hoʻoikaika nui ʻia nā mōlina hoʻouka uila no nā ʻāpana photovoltaic, kahi e waiho ai ke kila ma waho no nā makahiki he ʻumi a pono e paʻa i ka makani, ka ua, a me nā loli o ka mahana.

GI, GL, a i ʻole ZAM—pehea ʻoe e koho ai?

Eia ka manaʻo pololei. ʻO GI kāu koho kālā. Hana maikaʻi ia no ka hoʻohana ʻana i loko a i ʻole waho, a ʻo ia ke kūlana o ka ʻoihana no nā makahiki he ʻumi. ʻO GL ka piʻi ʻana—ʻoi aku ka palekana o ka pala, ʻoi aku ka maikaʻi o ka hoʻomanawanui wela, a he kūpono ke kumukūʻai. ʻO ia kahi kūpono no ka hapa nui o nā noi hale waho. A laila loaʻa iā ʻoe ʻo ZAM, kahi e hoʻohui ai i ka magnesium i loko o ka hui. ʻO kēlā hoʻololi liʻiliʻi e hana i kahi ʻokoʻa nui ma nā kihi ʻoki a me nā wahi i hōʻino ʻia—ʻo ka ho'ōla ponoʻī ka huaʻōlelo kaulana—no laila ʻālohilohi ʻo ZAM ma nā wahi kahakai, nā wahi haumia ʻoihana, a i ʻole kekahi papahana kahi i pipiʻi ai ka mālama ʻana a pono ʻoe i ke ola lōʻihi loa. Akā uku ʻoe no kēlā hana.

Hoʻokahi ʻōlelo aʻoaʻo hope loa

Mai nānā wale i ke kumukūʻai no kēlā me kēia tona. He mea hou kēlā. E helu i ke kumukūʻai holoʻokoʻa ma luna o ke ola o ka papahana. Hiki i kahi coil haʻahaʻa ke mālama iā ʻoe i ke kālā i kēia lā akā uku ʻoe i kahi pani hale i loko o ʻelima mau makahiki. Hana, manawa hoʻomaha, nā mea pani—hui koke kēlā mau mea. Eia kekahi, e hoʻomanaʻo he ʻoi aku ka paʻakikī o ka uhi ʻana o GL ma mua o GI, no laila ʻoi aku ka paʻakikī o ka mea hana i ka stamping a me ka punching. Pono ka welding i nā hoʻonohonoho ʻokoʻa iki. ʻAʻole kekahi o ia mea he mea haki, akā he mau mea ia āu e makemake ai e ʻike i ka wā e komo ai.

I ka hopena o ka lā, aia ʻo GL ma kahi kūlana maikaʻi loa ma ke kaʻina waiwai. ʻAʻole ia ka mea makepono loa, ʻaʻole hoʻi ka mea pipiʻi loa, akā no ka hapa nui o nā hana kūkulu hale a me nā hana kuhikuhipuʻuone o waho, he koho paʻa a hōʻoia ʻia. E hoʻohālikelike iā ia i ke kaiapuni kūpono, a e lawelawe maikaʻi ia iā ʻoe no nā makahiki.
