ʻO Dacromet Coating vs. Hot-Dip Galvanizing: ʻO wai ka pale ʻana i kūpono no kāu papahana?
2026-04-30
ʻO Corrosion ka ʻenemi kūmau o kēlā me kēia hale kila. ʻO ke koho ʻana i ka ʻenehana uhi pono hiki ke ʻike i ka ʻokoʻa ma waena o kahi mea hoʻopaʻa paʻa i mau makahiki he 10 a me ka mea i hāʻule i ka 2. Ma Fujinrui, kōkua mākou i nā ʻenekinia a me nā hui kūʻai ma ka honua holoʻokoʻa e hoʻoholo i ka ʻike. I kēia lā, hoʻokaʻawale mākou i nā ʻōnaehana hoʻohālikelike ʻelua i hoʻohālikelike ʻia: ʻO Dacromet a ʻO ka hoʻoheheʻe wela (HDG).
Hoʻohālikelike Poʻo-i-Poʻo
| Hiʻona | ʻO ka uhi ʻana o Dacromet | Hoʻohu wela |
| Pale ʻino | 800–1,200 hola (paʻakai paʻakai) | 400–600 hola (paʻakai paʻakai) |
| Ka Mahana Hana | A hiki i 300°C | A hiki i 250°C |
| Hoʻohāhā ʻana i ka waihā | ʻAʻohe pilikia (kaʻina hana ʻole ʻia) | Pilikia me nā wili ikaika kiʻekiʻe |
| Mānoanoa uhi | 4–8 μm (ka lahilahi) | 40–80 μm (papa mānoanoa) |
| Pili Pili | ʻAʻohe mea pili i ke kaula | Pono pinepine ka ʻoki hou ʻana i ke kaula |
| Ka hopena o ke kaiapuni | ʻO Cr6+-noa, ʻoluʻolu kaiaola | Hoʻokuʻu ʻia ka uahu zinc |
| Hoʻopau i ke ʻano | Kālā-hina, ʻaʻahu | ʻO ke kumu hoʻohālike zinc spangle |
| Pono No | Kiʻekiʻe-pololei & automotive | Kūleʻa & waho |
No ke aha e koho ai nā ʻenekinia hou iā Dacromet
- ʻOi aku ka maikaʻi o ka hoʻoinu ʻana i ka paʻakai: ʻOi aku ka maikaʻi o ka HDG ma o 2-3x i nā hoʻāʻo ʻana i ka paʻakai paʻakai kūʻokoʻa, no laila kūpono ia no nā kaiapuni kai a me ka haʻahaʻa haʻahaʻa.
- ʻAʻohe hoʻoheheʻe hydrogen: Hoʻopau i ka pilikia o ka hāʻule koke ʻana o ka bolt ma nā mea hoʻopaʻa ikaika kiʻekiʻe (papa 10.9 a ma luna) - kahi pono palekana koʻikoʻi.
- Ka mālama pono ʻana i ka milo: ʻO ka uhi ʻili lahilahi e hoʻopaʻa pono i nā bolts a me nā nati me ka ʻole o ka hana hou ʻana i ke kaula ma hope o ka uhi ʻana.
- ʻO ROHS & ISO Compliant: Hoʻokō i nā kūlana kaiapuni EU. He kūpono no nā mākeke kaʻa, uila, a me nā mākeke koʻikoʻi i waho.
I ka manawa e noʻonoʻo ai i ka hoʻoheheʻe wela wela
Noho mau ʻo HDG i kahi koho kumu kūʻai no nā bolts kūkulu nui a me nā papahana hoʻolālā waho kahi ʻaʻole ʻo nā pōʻino koʻikoʻi ka mea e hopohopo nui ai. ʻOi aku ia i nā noi nui kahi e hāʻawi ai kahi papa zinc mānoanoa i ka pale mechanical. Eia nō naʻe, no nā mea hoʻopili pololei a me nā noi palekana-koʻikoʻi, ʻoi aku ka nui o Dacromet i ka hopena makemake.
