Ua ʻike maopopo ʻia ka maikaʻi onā paipu huinahā a me nā ʻāpana huinahā i hoʻoheheʻe ʻiaa me ke ʻano o ke kau ʻana e hoʻopilikia pololei i ke kūpaʻa o nā hale kila.
I kēia manawa, ʻo nā mea kākoʻo ma ka mākeke he kila kalapona. ʻO nā mea maka o ke kila kalapona he Q235 a me Q345, i mālama ʻia e ka galvanizing wela. Hana ʻia ke kākoʻo me ka ʻōwili kila ʻāpana ma o ke kulou anu, ka hoʻoheheʻe ʻana, ka galvanizing wela a me nā kaʻina hana ʻē aʻe. Ma ke ʻano laulā, pono e ʻoi aku ka mānoanoa ma mua o 2mm, a ʻoi aku hoʻi no kekahi mau wahi kahakai, nā hale kiʻekiʻe a me nā wahi makani ʻē aʻe, ua ʻōlelo ʻia ʻaʻole e emi ka mānoanoa ma mua o 2.5mm, inā ʻaʻole aia kahi pilikia o ka haehae ʻana ma ke kiko pili kila.
I loko o nā hale nui, nonā paipu huinahā a me nā ʻāpana huinahā i hoʻoheheʻe ʻia me ke kila kalapona, ʻehia ka mānoanoa o ka uhi zinc e pono e hoʻokō ʻia e hoʻokō ai i nā koi o ke ola lawelawe ʻana i ka palaho o ke kaiapuni?
E like me kā kākou e ʻike nei, ʻo ka mānoanoa o ka galvanizing wela-dip kahi mea nui o ka maikaʻi a me ka ʻenehana kuhikuhi opaipu huinahā galvanized, e pili ana i ka palekana a me ke kūpaʻa o ka hale. ʻOiai aia nā kūlana aupuni a me nā kūlana ʻoihana, ʻo ka mānoanoa o ka uhi zinc kūpono ʻole o ke kākoʻo he pilikia loea ākea nō ia o ke kākoʻo.
ʻO ke kaʻina hana galvanizing wela-dip kahi hoʻolālā mālama ʻili kila paʻa a hilinaʻi hoʻi e pale aku i ka palaho o ke kaiapuni. Nui nā mea e hoʻopilikia ai i ka galvanizing wela-dip, e like me ke ʻano o ke kila kila, ke kūlana waho (e like me ka ʻoʻoleʻa), ke kaumaha o loko o ka substrate, a me kekahi mau nui. I loko o kēia kaʻina hana, ʻoi aku ka hopena o ka mānoanoa o ka substrate i ka mānoanoa o ka galvanizing wela-dip. Ma keʻano laulā, ʻo ka mānoanoa o ka papa, ʻoi aku ka nui o ka mānoanoa o ka galvanizing wela-dip. Lawe ʻia ke kākoʻo me ka mānoanoa o 2.0mm ma ke ʻano he laʻana e hōʻike i ka nui o ka mānoanoa o ka uhi zinc e pono ai e hoʻokō i nā koi ola lawelawe palaho o ke kaiapuni.
Manaʻo ʻia he 2mm ka mānoanoa o ka mea kumu kākoʻo, e like me ke kūlana maʻamau GBT13192-2002 wela galvanizing.
He aha ka mānoanoa o ka papa galvanized o ka paipu huinaha galvanized e pono ai e hoʻokō i nā koi ola lawelawe?
Paipu huinahā galvanized
Wahi a nā koi o ke kūlana aupuni, ʻaʻole pono e emi ka mānoanoa o ka mea kumu 2mm ma mua o 45 μm. ʻAʻole pono e emi ka mānoanoa like ma mua o 55 μm. Wahi a nā hopena o ka hoʻāʻo ʻana i ka lewa i mālama ʻia e ka Japanese Hot Dip Galvanizing Association mai 1964 a 1974. He aha ka mānoanoa o ka papa galvanized o ka paipu huinaha galvanized e pono ai e hoʻokō i nā koi o ke ola lawelawe?
Inā helu ʻia e like me ke kūlana aupuni, ʻo ka nui o ka zinc he 55x7.2=396g/m2,
ʻO ke ola lawelawe i loaʻa ma nā ʻano ʻokoʻa ʻehā e pili ana i:
ʻĀpana ʻoihana kaumaha: 8.91 mau makahiki, me ke kekelē pala makahiki o 40.1;
ʻĀpana kahakai: 32.67 mau makahiki, me ke kekelē pala makahiki o 10.8;
Waho: 66.33 mau makahiki, me ke kekelē pala makahiki o 5.4;
Wahi kūlanakauhale: 20.79 mau makahiki, me ke kekelē palaho makahiki o 17.5
Inā helu ʻia e like me ke ola lawelawe photovoltaic o 25 mau makahiki
A laila ʻo ke kaʻina o nā ʻāpana ʻehā ma ka liʻiliʻi loa:
1002.5270135437.5, ʻo ia hoʻi, 139 μm, 37.5 μm, 18.75 μm, 60.76 μm.
No laila, no ka hoʻolaha ʻana o nā wahi kūlanakauhale, ʻo ka mānoanoa o ka uhi zinc ma ka liʻiliʻi he 65 μ M he mea kūpono a pono hoʻi, akā no nā wahi ʻoihana kaumaha, ʻoi aku hoʻi ka poʻe me ka pala waikawa a me ka alkali, ua ʻōlelo ʻia e hoʻohui pono ʻia ka mānoanoa o ka paipu huinaha galvanized a me ka uhi zinc.
