No ke aha ʻaʻole ʻōlelo ʻia ka zinc plating no nā bolts kiʻekiʻe? A he aha nā mea e hiki ke hoʻohana ʻia? Ka pale ʻana i nā bolts a me nā wīwī mai ka ʻino ʻole me ka ʻole o ka ikaika a palekana.

2026-05-12

I ka wa e hoakaka mai ai na enekinia bolts ikaika kiʻekiʻe (Papa 10.9, 12.9, a i ʻole ka ASTM A325/A490) no nā pilina kūkulu, manaʻo lākou i ka hoʻokō haʻahaʻa loa. Akā i ka wā e koi ʻia ai ka pale corrosion, ʻo ka manaʻo paʻamau ke kuhikuhi pinepine galvanizing zinc. Hiki ke pilikia kēlā koho.

ʻO ka pilikia kahi mea i kapa ʻia hoʻoheheʻe hydrogen - kahi ʻano hāʻule leo ʻole e hiki ai ke haʻihaʻi nā bolts me ka ʻole o ka ʻōlelo ʻana, nā lā a i ʻole nā wiki ma hope o ke kau ʻana. Eia ka mea e pono ai ʻoe e ʻike, a ʻo wai nā hoʻonā anti-corrosion palekana no ka kiʻekiʻe-tensile mea paa.

ʻO ka pōʻino huna: Hydrogen Embrittlement

I ka wā o ka kaʻina hana electroplating, hoʻokumu ʻia ka hydrogen atomic ma ke ʻano he hopena. Ke hoʻomoʻa nā bolts me ka ikaika tensile ma luna o 1,000 MPa (paʻakikī> 320 HV) i kēia hydrogen i loko o kā lākou lattice kila, ʻo ka hopena ka nalowale o ka ductility. Hiki i ka bolt ke hele i kēlā me kēia nānā maikaʻi, torque pololei ma ka pūnaewele, a laila hāʻule koke ma lalo o ka ukana maʻamau.

ʻO kēia lohi ʻole - me ka ʻole o ka plastic deformation a ʻaʻohe ʻōlelo aʻo ʻike ʻia - hoʻolilo i ka hydrogen embrittlement kekahi o nā pilikia koʻikoʻi loa i ka ʻenehana hana. No ka mea nā ʻūpoko poʻo kumu, nā kī hex, a me nā kūlana kiʻekiʻe ʻē aʻe mea paa hoʻohana ʻia i nā noi koʻikoʻi palekana (nā alahaka, nā turbines makani, ka hoʻokuʻu ʻana i nā kaʻa), hiki i nā hopena ke pōʻino.

ʻOiaʻiʻo: ʻAʻole hiki ke hōʻoia i ka hoʻopau piha ʻana o ka hydrogen ma ka papa 10.9 a me 12.9 bolts. ʻAʻole hāʻule ka pilikia i ka ʻole.

Pilikia Galvanizing e ka Bolt Grade

Papa Bolt	Ikaika U'i	HE Pilikia	Manaʻo
8.8	800 MPa	Haʻahaʻa	ʻAe ʻia ka Galvanizing
10.9	1,000 MPa	Kiʻekiʻe	E hoʻohana i ka zinc flake coating
12.9	1,200 MPa	koʻikoʻi	Zinc flake a i ʻole ke kila kila

ʻO ka galvanizing wela e lawe i ka pilikia hydrogen haʻahaʻa ma mua o ka electroplating, akā ʻo ka hoʻomaʻamaʻa mua ʻana i ka waika e hoʻokomo i ka hydrogen. No nā noi palekana kiʻekiʻe, ʻaʻole ia ke koho maikaʻi loa.

Palekana Anti-Corrosion Alternative

No laila pehea ʻoe e pale ai bolts ikaika kiʻekiʻe a wiliwili mai ka ʻōpala i ka wā e pau ai ka galvanizing mai ka papaʻaina? Eia nā mea ʻē aʻe i hōʻoia ʻia:

ʻO ka uhi ʻana o Zinc Flake (Dacromet / Geomet)

Hoʻohana ʻia me ka mechanically - ʻaʻohe wai ʻauʻau, ʻaʻohe electrolysis, ʻole hydrogen hanauna. Hāʻawi i 600-1,000+ mau hola pale paʻakai. He kūpono no ka papa 10.9 a me 12.9 bolts, screws, a me studs.

Koho maikai loa

Hoʻopalapala Zinc Mechanical

Hoʻokuʻu ʻia nā ʻāpana zinc ma ka ʻili hoʻopaʻa me ka ʻole o ka uila. ʻAʻohe pilikia hydrogen, kūpono i nā bolts hex kiʻekiʻe a me nā nati.

ʻAʻohe pilikia o ka hydrogen

Nā Paʻa Paʻa Kūleʻa

ʻO A316 a i ʻole A4 (316) nā wili kila kila a me nā wili e hāʻawi i ke kūpaʻa ʻino. ʻOi aku ka maikaʻi no nā kaiapuni kai, kemika, a me waho.

Hoʻoponopono Premium

Ka uhi ʻana o ka PTFE / Fluoropolymer

Hāʻawi maikaʻi i ka pale kemika a me ka haʻahaʻa haʻahaʻa. Hoʻohui pinepine ʻia me ka zinc underlayer no ka hoʻomaikaʻi ʻana i ka pale corrosion ma nā mea hoʻopili ʻoihana.

Hoʻohana Kūikawā

“Mālama ka pale anti-corrosion kūpono i kāu hoʻopukapuka. Hiki i ka mea hewa ke luku.”

— Hui Hana Hana FUJINRUI

Ke koho ʻana i ka Haʻina Pono

Ke koho ʻana i kahi lāʻau anti-corrosion no kou mea paa, e noʻonoʻo i kēia mau mea:

Papa Bolt— Hiki i ka papa 8.8 a lalo ke hoohana i ka galvanizing. No ka 10.9 a ma luna, e koho mau i ka zinc flake a i ʻole ke kila kila.
Kaiapuni— Ke koi aku nei na lewa moana a me na lewa hana i na hora paakai kii aku. Ka uhi Geometa nā kī kila kila maikaʻi ma ʻaneʻi.
Palapala noi— Pono nā kaʻa kaʻa, ikehu makani, a me ke kila hoʻohui ʻana i ka pilikia ʻole hydrogen. ʻO nā ʻōnaehana hoʻoheheʻe mīkini a me nā ʻōnaehana zinc flake ka maʻamau.
Kumukuai vs- Hāʻawi ka Zinc flake coatings (Dacromet, Geomet) i ke koena maikaʻi loa o ka pale ʻana i ka corrosion, palekana hydrogen, a me ke kumukūʻai no ka hapa nui o mea paʻa kaumahanā noi.

He aha ke ano o keia no ke kuai ana

No nā hui ʻimi a me nā mea ʻenekinia papahana, maopopo ka lawe ʻana: ʻaʻole paʻa i ka galvanizing no nā mea hoʻopaʻa ikaika kiʻekiʻe. E kuhikuhi mau i ka pae bolt a me ka corrosion, a e hana pū me kāu mea hana paʻa e koho i kahi ʻōnaehana pale e hoʻopau i ka pilikia o ka hoʻoheheʻe ʻana o ka hydrogen.

Ma FUJINRUI, hana mākou nā wili kūʻokoʻa, wiliwili, a nā mea hoʻopaʻa maʻamau me Dacromet, Geomet, mechanical zinc, a me PTFE coatings - i kūpono i kāu noi a me nā koi kaiapuni. Hoʻāʻo ʻia kēlā me kēia pūʻulu no ka ikaika mechanical a me ke kūpaʻa corrosion ma mua o ka hoʻouna ʻana.

Pono nā mea hoʻopaʻa kūʻē i ka ʻino?

E kiʻi i kahi ʻōlelo hoʻopiʻi manuahi a me ka ʻōlelo no kāu papahana. Pane kā mākou poʻe ʻenekinia i loko o 24 mau hola.
