ʻO nā pōmaikaʻi nui o nā huahana guardrail ala hot-dip galvanized

ʻO nā pōmaikaʻi nui o nā huahana guardrail highway hot-dip galvanized:

1. Ua hoʻopaʻa ʻia ka pale wela wela i ka guardrail mesh, a ua hoʻopili maikaʻi ʻole ʻia me ke kumu kolamu guardrail. ʻOi aku ka uhi ʻana ma mua o 80um. I ka wā e paʻi ʻia ai ka guardrail mesh, e ʻili maʻalahi ka uhi ʻana, a hiki mai ka infiltration zinc. ʻO ka zinc-iron alloy layer i hana ʻia e ke kaʻina hana he diffusion-type metallurgical bond, a hiki i ka papa infiltration ke piʻi aku ma mua o 100um. He kiʻekiʻe ka paʻakikī a me ka hoʻopili ikaika ʻana o ka papa o ka ʻili, a ʻaʻole e ʻili ka papa infiltration inā paʻa ia i ka wā o ka lawe ʻana.

2. Hoʻohaumia ʻia ka lewa o ka zinc vapor i hoʻokuʻu ʻia ma ke kaʻina hana galvanizing wela o ka pā haʻuki, a ʻo ka wai zinc wela kiʻekiʻe i paʻi ʻia e ka "pana" e hoʻoweliweli i ka palekana pilikino. Eia nō naʻe, hoʻopau ʻia ka infiltration zinc vacuum i loko o kahi pahu pani, kahi e hoʻopau loa ai i ka hopena o ka zinc vapor ma ka lewa. Ua hoʻopau loa ka pollution i ka mōʻaukala o ka ʻawaʻawa zinc a me ka wela wela o ka wai zinc no nā mea hana.

3. Hoʻohālikelike ʻia me ka galvanizing hot-dip, aia kekahi ʻokoʻa hou ma mua o ka galvanizing hot-dip galvanizing no ka mesh guardrail, a paʻakikī ke kāohi ʻana i ka mānoanoa o ka uhi. Inā "ma luna o ka maʻamau" (ʻoi aku ka mānoanoa o ka uhi) a i ʻole "ma waho o ka maʻamau", maʻalahi ke hoʻemi i ke ʻano. Ma ke kuleana o nā mea hoʻopaʻa, ʻaʻole i hoʻoholo ʻia ka pilikia o ka hoʻomanawanui; me ka vacuum zinc infiltration, hiki ke hoʻomaluʻia ka mānoanoa zinc infiltration ma ka laulā o 15 a hiki i 100um, aʻo ka mānoanoa o ka zinc layerʻaʻole makemake i nā āpau hou ma waena o 30 a 50um, e hoʻopau loa i ka hoʻomanawanui. ʻO nā pilikia kūpono e hoʻomaikaʻi i ka hopena paʻa.

Mea: uea kila kalapona haʻahaʻa, uea alumini-magnesium alloy.

ʻO ka ulana ʻana a me nā hiʻohiʻona: wili a welded, anti-corrosion, anti-aging, pale ʻana i ka lā, kū i ka wā a me nā ʻano ʻē aʻe. ʻO nā ʻano anti-corrosion e pili ana i ka electroplating, ka hoʻoheheʻe ʻana i ka wela, ka hoʻoheheʻe ʻana i ka plastic, a me ka ʻū ʻana i ka plastic.

Hoʻohana: Hoʻohana ʻia no ka pale guardrail ma nā alanui, nā kaʻaahi, nā mokulele, nā wahi noho, nā awa, nā māla, ka hānau ʻana, nā holoholona, ​​etc.
