Nūhou - Nā kikoʻī, nā waiwai, nā ʻano a me nā kumukūʻai o Galvanized Steel C Channel

He kila C-like Galvanizedhe ʻano kila hou ia i hana ʻia mai nā ʻili kila ikaika loa i kū anuanu a ʻōwili ʻia. ʻO ka mea maʻamau, ʻo nā wili puʻupuʻu wela wela ke anu-pee e hana i kahi ʻāpana keʻa C.

He aha ka nui o ke kila C-channel galvanized?

Nā kūlana pili: Loaʻa nā kūlana maʻamau i ka ASME, ASTM, EN, BS, GB, DIN, JIS, a me nā mea'ē aʻe. Ua pili nā kūlana likeʻole i nā māhele likeʻole a me nā māhele noi.

Kaʻina hana Galvanizing:

1.Electrogalvanized C-Channel Steel:
Electrogalvanized C-channel kilahe huahana kila i hana ʻia ma ka waiho ʻana i kahi papa zinc ma ka ʻili okila C-channel i hoʻokumu ʻia anuka hoʻohana ʻana i kahi kaʻina hana electrolytic. ʻO ke kaʻina hana koʻikoʻi ka hoʻokomo ʻana i ke kila awāwa e like me ka cathode i loko o kahi electrolyte i loaʻa nā ion zinc. Hoʻopili ʻia kēia manawa i ka ʻili kila, e hoʻoheheʻe ʻia nā ion zinc ma waena o ka ʻili kila, e hana ana i kahi uhi zinc maʻamau 5-20μm mānoanoa. ʻO nā mea maikaʻi o kēia ʻano kila kanal, he ʻili maʻemaʻe, ka uhi zinc like ʻole, a me ke ʻano keʻokeʻo kālā keʻokeʻo. Hāʻawi ka hana ʻana i ka hoʻohana ʻana i ka ikehu haʻahaʻa a me ka hopena wela liʻiliʻi ma ka substrate kila, me ka mālama pono ʻana i ka pololei mechanical maoli o ke kila C-channel. He mea kūpono kēia no nā noi e koi ana i nā kūlana nani kiʻekiʻe a ma nā wahi ʻino ʻino, e like me nā hale hana maloʻo i loko, nā pale hale, a me nā papa hana māmā. Eia nō naʻe, hāʻawi ka ʻili zinc lahilahi i ka pale ʻana i ka corrosion, e hopena i kahi ola lawelawe pōkole (maʻamau 5-10 mau makahiki) ma nā wahi haʻahaʻa, kahakai, a i ʻole nā ʻoihana haumia. Eia kekahi, ʻoi aku ka nāwaliwali o ka hoʻopili ʻana o ka zinc a hiki ke hoʻokaʻawale ʻia ma hope o ka hopena.

2.Hot-Dip Galvanized C-Channel Steel:
Ke kila C-kanal hoʻopaʻa welahana ʻia ma ke anu-piʻi, pickling, a laila hoʻokomo i ke kila holoʻokoʻa i loko o ka zinc hehee ma 440-460°C. Ma o ka hopena kemika a me ka hoʻopili kino ʻana ma waena o ka zinc a me ka ʻili kila, ua hoʻokumu ʻia kahi ʻāpana hui o ka zinc-iron alloy a me ka zinc maʻemaʻe me ka mānoanoa o 50-150μm (a hiki i 200μm a i ʻole ma kekahi mau wahi). ʻO kāna mau pōmaikaʻi nui, ʻo ia ka papa zinc mānoanoa a me ka hoʻopili ikaika ʻana, hiki ke uhi piha i ka ʻili, nā kihi a me loko o nā lua o ke kila kahawai e hana i kahi pale anti-corrosion piha. ʻOi aku ka nui o kona kūpaʻa corrosion ma mua o nā huahana electro-galvanized. Hiki i kona ola lawelawe ke hiki i 30-50 mau makahiki ma nā wahi kaiapuni maloʻo a me 15-20 mau makahiki ma nā kahakai a i ʻole nā ʻoihana ʻoihana. I ka manawa like, ʻo ke kaʻina hana galvanizing wela ka hiki ke hoʻololi i ke kila a hiki ke hana ʻia me ka nānā ʻole i ka nui o ke kila channel. Hoʻopaʻa paʻa ʻia ka papa zinc i ke kila ma nā wela kiʻekiʻe a he hopena maikaʻi loa a me ke kūpaʻa ʻaʻahu. Hoʻohana nui ʻia ia i nā hale kila waho (e like me ke kūkulu ʻana i nā purlins, nā pale kiʻi kiʻi kiʻi, nā kiaʻi alaloa), nā papa hana kaiapuni haʻahaʻa (e like me nā keʻena mālama wai) a me nā hiʻohiʻona ʻē aʻe me nā koi pale corrosion kiʻekiʻe. Eia naʻe, e ʻike ʻia kona ʻili i ka pua aniani hina-hinahina, a ʻoi aku ka haʻahaʻa o ka ʻike ʻana ma mua o nā huahana electro-galvanized. Eia kekahi,ʻo ke kaʻina hana he nui ka ikehu a loaʻa ka hopena wela iki ma ke kila.

He aha nā kumukūʻai o ke kila C-channel galvanized?

Galvanized C channel kila Kumukuaiʻaʻole ia he waiwai paʻa; akā, ke hoʻololi nei i ka dynamically, i hoʻopili ʻia e ka hui pū ʻana o nā kumu. ʻO kāna kumu kūʻai kumu kūʻai e hoʻohuli a puni ke kumukūʻai, nā kikoʻī, ka lako mākeke a me ke koi, a me ka waiwai i hoʻohui ʻia.

Mai kahi hiʻohiʻona kumukūʻai, ʻo ke kumukūʻai o ke kila (e like me Q235, Q355, a me nā māka ʻē aʻe o ka ʻōwili wela wela) ʻoiai ʻo ke kumu kumu kumu ke kī nui. ʻO ka 5% fluctuation i ke kumukūʻai mākeke o ke kila e alakaʻi maʻamau i kahi 3% -4% hoʻololi kumukūʻai noKanal GI C.

Eia kekahi, ʻokoʻa i nā kaʻina hana galvanizing nui ka hopena i nā kumukūʻai. ʻOi aku ka nui o ka galvanizing wela ma mua o 800-1500 RMB/ton ma mua o ka electrogalvanizing (5-20μm mānoanoa) ma muli o kona mānoanoa zinc layer (50-150μm), ʻoi aku ka nui o ka ikehu, a me ka hana paʻakikī.

Ma nā ʻōlelo kikoʻī, ʻokoʻa nā kumukūʻai ma muli o nā ʻāpana huahana. No ka laʻana, ʻo ke kumukūʻai mākeke no kahi kumu hoʻohālike maʻamau C80 × 40 × 15 × 2.0 (kiʻekiʻe × laulā kumu × kiʻekiʻe ʻaoʻao × mānoanoa pā) ma waena o 4,500 a me 5,500 yuan/ton. Eia nō naʻe, ʻo ke kumukūʻai o kahi kumu hoʻohālike C300 × 75 × 20 × 3.0 nui aʻe, ma muli o ka hoʻonui ʻana i ka hoʻohana ʻana i nā mea maka a me ka hoʻonui ʻana i ka paʻakikī o ka hoʻoili ʻana, piʻi pinepine i 5,800 a 7,000 yuan/ton. ʻO nā lōʻihi i hana ʻia (e laʻa, ma luna o 12 mau mika) a i ʻole nā koi kūikawā o ka mānoanoa o ka paia e loaʻa pū kekahi 5% -10% uku hoʻonui.

Eia kekahi, ʻo nā kumu e like me ke kumukūʻai kaʻa (e laʻa, ka mamao ma waena o ka hana ʻana a me ka hoʻohana ʻana) a me nā kumukūʻai hōʻailona hoʻi i ke kumu kūʻai hope. No laila, i ke kūʻai ʻana, pono nā kūkākūkā kikoʻī me nā mea hoʻolako e pili ana i nā pono kikoʻī e loaʻa ai kahi ʻōlelo kūpono.
