Ka paakiki ʻoi aku paha ma mua o nā lole'ē aʻe, e pili ana i nā hopena wikiwiki.

I ka wā e koho ai i nā pāpale'ē aʻe ma luna o Galvalizing

Nā noi kiko'ī kiʻekiʻe → makemake ʻO nā'ōnaehana pālolo a iʻole nā'ōnaehana duplex.
ʻO nā mea hoʻohālikelike a iʻole ke kiʻekiʻe ph / haʻahaʻa haʻahaʻa → e hoʻohana Nā Lānaehana EPYOxy / PweureThane Pūnaehana.
ʻO nā'āpana kiʻekiʻe → makemake Hoʻololi Oole Memothing no ka mānoʻano i hoʻopaʻaʻia.
ʻO ka Expsire Marine → ka pū Duplex (HDG + epoxy a iʻole polyurethane topcocoat) ua manaʻoʻia.
Nā mea kūponoʻole → e hoʻohana 304/316 kila kohu ʻole I ka Aesthetics, Hingiene, a iʻole e koiʻia ai ka durability.

10. ʻO nā hiʻohiʻona hou a me nā makemakeʻole

ʻO kaʻoihana Galvalizingʻo ia ka holo wikiwikiʻana, ka hoʻokeleʻana e ka hoʻonuiʻana i nā koi no ka hana hoʻonui, keʻano o ka honua, a me ka uku uku.

Holomua a hoʻohuiʻia:

Nā hana kū'ē e like me ka zinc-alumini-agnisumi (ZN-al-mg) Hāʻawiʻo Alloys i ke kū'ē kū'ē, nui loa ma nā wahi hoʻohālikelike, ʻOiai e hōʻemi ana i kaʻai zinc.

Hōʻike kēia mau lole i ka hoʻomaikaʻiʻana i nā waiwai pilikino a me nā ola lawelawe i hoʻohālikelikeʻia e hoʻohālikelikeʻia i nā lole kuʻuna zin.

Pūnaehana Dheplex:

Hoʻohui pū me Galvalizing me nā kāhiko a iʻole nā pale o nā mea kanu a iʻole nā pale.

Hāʻawi nā loleʻo Duplex i ka pale o Synergistic, kānalua a iʻole he huakaʻi hele i ke ola o Galvanized Steel, ʻoi aku ma nā wahi o Harsh a iʻole nā hoʻonohonohoʻoihana.

Akamai a me ka ho'ōlaʻana iāʻoe iho:

Ke holomua nei ka noiʻiʻana i nā lole i hoʻopiliʻia me nā micrcapsules a iʻole nanoparticles e hoʻokuʻu i nā inohibors ma luna o ka hōʻino.

ʻO kēia mau'ōnaehana Smart e hoʻonui ai e hoʻolōʻihi i ke ola lawelawe a hōʻemi i ka mālamaʻana ma o autonomously e hoʻoponopono hou ana i nā hemahema.

ʻO ka hoʻokele kaiāulu a me nā hoʻomaikaʻiʻana:

Nā innovations i loko o Flux Chemistry, loko o ka hoʻonohonohoʻana, a me nā hana recycling i manaʻoʻia e hoʻohaʻahaʻa i ka wāwae o ke kaiāulu o Galvalizing.

ʻO nā mea kūʻai akuʻole e lawe i nā mea kūʻai aku i nā mea kūʻai aku e pili ana i nā mea e pili ana i nā mea e hoʻopili ai i nā recurs statisties.

ʻO ka hoʻopili a me ka mana kūpono:

Holomua ma ka automation a me ka manawa maʻamau, ho'ēmi i ka pauʻole, a me ka hoʻomaikaʻiʻana i ka hana kūpono ma ka papaʻainaʻelua a hoʻomau i ka hana galnivalizing.

11. Hopena

ʻO Galvalizing e waiho ana i kahiʻenehana waiwai no ka paleʻana i ka kila a me ka hao ma waena o nāʻoihana, ka hoʻihoʻiʻana i ka paleʻana o ka modropicical bintrochelical i ka paleʻana i ka mea i hoʻonui nui i nāʻano he nui a me ka ho'ēmiʻana i nā uku mālama.

ʻO nāʻano hana likeʻole o Galnivalizing-mai Hot-DiP i nā pono noi e pili ana i ka noi, ke kāohi nei i ka paʻa a me nā aesthetics.

ʻO nā kāpenaʻo Galvanized i ke kū'ēʻana, inainaahoi, a me nā mīkini hana, e hana pono ana iā lākou e kūkulu, aitompetitive, mahiai, ikaika, a me nā meaʻala.

ʻOiai e like me ka paʻakikī e like me ka hydrogen embrittlement a me ka papa mua, ʻO ke kumukūʻai o Galvalizing a me ka palekana o Galvalizing.

Nānā i mua, ʻO nā mea hoʻonāukiuki e like me nā mea nui a Alloy, Pūnaehana Dheplex, a me nā mea hoʻonaninani pilikino pilikino e hoʻonui ai e hoʻonui i ka mālamaʻana o Galani, durability, a me ka hoʻololiʻana,

ʻO ka hōʻoiaʻana i kāna hana koʻikoʻi i loko o kaʻoihana o kēiaʻoihana a me nā pale infrastructure e hoʻomau i ka wā e hiki mai ana.

FaqS

1. He aha ke galvalizing, a no ke aha i lilo ai ia?

ʻO Galvalizing ke kaʻina hana o ka hoʻopiliʻana i kahi pale pale pale pale i ke kila a iʻole ka hao e pale ai i ka corrosion.

Hoʻonui ia i ke ola o nā'āpana metala me ka hāʻawiʻana i ka mālama mālamaʻana a me kahi paʻa kino kino.

2. Pehea ka lōʻihi o kahi kāhikoʻo Galvalized?

Ke hilinaʻi nei i ke kaiāulu a me ka mānoanoa, Hiki i nā kila Galvalized ke hele ma kahi āpau 40 e luna 75 mau makahiki i nā kūlana maikaʻi, ʻoi aku ka lōʻihi ma mua o ke kila.

3. He aha nāʻano nui o Galvalizing?

Hoʻokomoʻia nā hana mua i nā galnizing wela, electrogalvalizy, ʻO ka hānai, a me nā wahiʻike, Ua kūpono kēlā me kēia no nā lako likeʻole, Kūkuʻi, a me nā koi noi.

4. Hiki ke kiʻiʻiaʻo Galvavanized kila?

ʻAe, ʻO ka penaʻana ma luna o ke kila galvanized maʻamau e hoʻonui i nā aesthetics a hāʻawi i ka pale hou, ʻO nā mea nui ma nā papa inoa inoa a me nā noi moana.
