Ua ʻike ʻia ka maikaʻi opaipu galvanized square a me rectangulara ʻo ke ʻano o ka hoʻokomo ʻana e pili pono i ka paʻa o nā hale kila.
I kēia manawa, ʻo nā mea kākoʻo ma ka mākeke ka nui o ke kila kalapona. ʻO nā mea maka o ke kila kalapona ka Q235 a me Q345, i mālama ʻia e ka galvanizing wela. Hana ʻia ke kākoʻo me ka wili kila ma o ke kuʻi anu, ka wili, ka galvanizing wela a me nā kaʻina hana ʻē aʻe. ʻO ka maʻamau, ʻoi aku ka nui o ka mānoanoa ma mua o 2mm, a ʻoi aku hoʻi no kekahi mau kahakai, kiʻekiʻe a me nā wahi makani ʻē aʻe a me nā wahi, ʻōlelo ʻia ʻaʻole e emi ka mānoanoa ma mua o 2.5mm, inā ʻaʻole hiki ke haehae i ke kila. wahi pili.
Ma na hale nui, nocarbon steel galvanized square and rectangular pipes, ehia ka mānoanoa o ka zinc coating e pono e hoʻokō i nā koi o ke ola lawelawe corrosion kaiapuni?
E like me kā mākou e ʻike ai, ʻo ka mānoanoa o ka galvanizing hot-dip he mea koʻikoʻi koʻikoʻi a me ka ʻenehana ʻenehanapaipu huinahalike galvanized, pili i ka palekana a me ka lōʻihi o ka hale. ʻOiai aia nā kūlana ʻāina a me nā ʻoihana, ʻo ka mānoanoa o ka zinc coating ʻaʻole i kūpono i ke kākoʻo ʻo ia ka pilikia ʻenehana ākea o ke kākoʻo.
ʻO ke kaʻina hana galvanizing wela ke kūpaʻa a hilinaʻi hoʻi i ka papa hana lapaʻau e pale aku i ka ʻino kaiapuni. Nui nā kumu e pili ana i ka galvanizing wela, e like me ke ʻano o ka substrate kila, ka mokuʻāina o waho (e like me ka roughness), ke koʻikoʻi kūloko o ka substrate, a me nā ʻano nui. I loko o kēia kaʻina hana, ʻoi aku ka nui o ka mānoanoa o ka substrate i ka mānoanoa o ka galvanizing hot-dip. ʻO ka maʻamau, ʻoi aku ka mānoanoa o ka pā, ʻoi aku ka nui o ka mānoanoa o ka galvanizing hot-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 o ka lawelawe corrosion.
E noʻonoʻo i ka mānoanoa o ka waihona kumu kākoʻo he 2mm, e like me ka maʻamau GBT13192-2002 wela galvanizing maʻamau.
He aha ka mānoanoa o ka galvanized papa o galvanized square paipu i koi 'ia e hālāwai me ka lawelawe ola koi?
Paipu huinahalike Galvanized
E like me nā koi o ke kūlana aupuni, ʻaʻole pono ka mānoanoa o ka waihona kumu 2mm ma lalo o 45 μm. ʻAʻole pono e emi iho ka mānoanoa like ʻole ma mua o 55 μm. E like me 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 galvanized layer o galvanized square pipe pono e hoʻokō i nā koi ola lawelawe. ?
Inā helu ʻia e like me ke kūlana aupuni, ʻo ka ʻike zinc he 55x7.2=396g/m2,
ʻO ke ola lawelawe i loaʻa i loko o ʻehā mau kaiapuni like ʻole e pili ana:
Wahi ʻoihana kaumaha: 8.91 mau makahiki, me ka degere corrosion makahiki o 40.1;
Wahi kahakai: 32.67 makahiki, me ka degere corrosion makahiki o 10.8;
Ma waho: 66.33 makahiki, me ka degere corrosion makahiki o 5.4;
Wahi kūlanakauhale: 20.79 mau makahiki, me ka degere corrosion makahiki o 17.5
Inā helu ʻia e like me ke ola lawelawe photovoltaic o 25 mau makahiki
A laila, ʻoi aku ka liʻiliʻi o ke kaʻina o nā ʻāpana ʻehā:
1002.5270135437.5, ʻo ia hoʻi, 139 μm, 37.5 μm, 18.75 μm, 60.76 μm.
No laila, no ka hāʻawi ʻana i nā kūlanakauhale, ʻo ka mānoanoa o ka zinc coating ma ka liʻiliʻi loa he 65 μM kūpono a pono, akā no nā wahi ʻoihana koʻikoʻi, ʻoi aku ka poʻe me ka waika a me ka alkali corrosion, ua ʻōlelo ʻia ʻo ka mānoanoa o ka paipu square galvanized. a e hoʻohui pono i ka zinc coating.
