Whakakikoruatanga Dacromet vs. Hot-Dip Galvanizing: Ko tehea te Parenga Waikura e tika ana mo to Kaupapa?
2026-04-30
Ko te waikura te hoariri puku o ia hanga maitai. Ma te kowhiri i te hangarau whakakikorua tika ka taea te rerekee i waenga i te whakamaarama ka roa te 10 tau me te kotahi ka taka ki te 2. I Fujinrui, ka awhina matou i nga miihini me nga roopu hoko o te ao ki te whakatau whakatau. I tenei ra, ka wehewehea e matou nga punaha whakakikorua e rua e tino rite ana: Dacromet a Piauau Werawera (HDG).
Mahunga-ki-Upoko Whakataurite
| Āhuahira | Te paninga Dacromet | Hot-Dip Galvanizing |
| Te Waihanga Atete | 800–1,200 haora (te rehu tote) | 400–600 haora (te rehu tote) |
| Te Waahi Mahi | Tae atu ki te 300°C | Tae atu ki te 250°C |
| Te Whakakorenga Hauwai | Karekau he morearea (te mahi tunu-kore) | Morearea ki nga tutaki kaha teitei |
| Matotoru paninga | 4–8 μm (te kikokore) | 40–80 μm (paparanga mātotoru) |
| Whakauru Miro | Kaore he raruraru miro | Me tapahi ano te miro |
| Te Painga Taiao | Cr6+-kore, pai-taiao | Ko te kohukohu konutea |
| Whakaoti Te ahua | Hiriwa-hina, kākahu | tauira konutea spangle |
| Pai Mo | Te tino tika me te motuka | Hanganga me waho |
He aha i whiriwhiria e nga miihini maha ake a Dacromet
- Mahinga Tote Rehu Kairangi: He pai ake i te HDG ma te 2–3x i roto i nga whakamatautau rehu tote kore, he pai mo nga taiao moana me te haumākū nui.
- Karekau he hauhautanga whakangao: Ka whakakore i te tupono o te kore ohorere o te raka i runga i nga toromoka kaha-nui (te karaehe 10.9 me runga ake) — he painga nui mo te haumaru.
- Tiaki Miro Tika: Ko te paninga tino angiangi ka whakarite kia uru pai nga raka me nga nati me te kore e mahi ano te miro i muri i te paninga.
- RoHS & ISO Whakaritenga: Ka tutuki nga paerewa taiao a EU. He pai mo nga maakete miihini, hikohiko, me nga maakete tairongo ki te kaweake.
Ko te wa e whakaaro ai ko te Hot-Dip Galvanizing
Ka noho tonu te HDG hei kowhiringa utu-utu mo nga raka hanga nui me nga kaupapa hangahanga o waho kaore nga huringa waikura nui rawa atu ko te awangawanga tuatahi. He pai ake i roto i nga tono nui kei reira te paparanga konutea matotoru hei whakamarumaru miihini. Heoi, mo nga whakapiringa tika me nga tono haumaru-arohaehae, ko Dacromet te mea pai ake.
