I-Dacromet Flange Bolts
2026-07-23
I-Dacromet Flange Bolts
Ama-Anti-Corrosion Flange Fasteners ane-Zinc-Aluminium Flake Coating
Amabhawodi e-Dacromet flange ahlanganisa ukwakheka kwekhanda le-flange elilayisha umthwalo ne-Dacromet zinc-aluminium flake coating. I-flange ebalulekile ithatha indawo ye-washer ehlukile, kuyilapho i-Dacromet enamathela iletha amahora angu-500-1,200 wokumelana nesifutho sikasawoti ngaphandle kwe-hydrogen embrittlement - ilungele ukusetshenziswa kwezimoto, ukwakhiwa, nolwandle.
Ingxenye 1 - I-Flange Bolt
Ibhawodi ye-flange iyibhawodi lekhanda le-hex eline-flange efana newashi ehlanganisiwe esisekelweni sekhanda. I-flange isabalalisa umthwalo we-clamping endaweni ebanzi, inciphisa ukucindezela kwendawo futhi ivimbele ukulimala ezintweni ezixhunyiwe. Lokhu kuqeda isidingo se-washer ehlukile, umhlangano owenza lula.
Izici Eziyinhloko
- Ukusatshalaliswa komthwalo: I-Flange isakaza amandla okubamba, ehlisa ingcindezi ngokufika ku-50% uma kuqhathaniswa namabhawodi e-hex ajwayelekile.
- Anti-ukukhululwa: Inketho ye-Serrated flange inikeza ukumelana nokudlidliza okwakhelwe ngaphakathi ngaphandle kokukhiya amawasha.
- Amazinga: I-DIN 6921 / ISO 4162 / GB/T 5787; i-M6–M20; IBanga 8.8 kanye ne-10.9 nge-ISO 898-1.
- Izinto zokwakha: Insimbi ye-Carbon (iBanga lesi-8.8) noma insimbi ephansi ye-alloy (iBanga le-10.9), icishiwe futhi ithukuthele.
Ingxenye 2 - I-Dacromet Coating
I-Dacromet iyinalethi esekwe emanzini, engeyona eye-electrolytic ye-zinc egqagqene kanye nama-aluminium flakes ahlanganiswe yizinhlanganisela ze-chromium. Isetshenziswa ngemijikelezo ye-dip-spin-cure ku-280–300°C, ihlinzeka ngokuvikela ukugqwala kwezendlalelo ezintathu ngaphandle kokumbozwa kwe-hydrogen.
I-Protection Mechanism
- Ukuvikelwa komhlatshelo: Ama-zinc flakes agqwala ngokukhethekile ukuze avikele insimbi, noma ngabe ukunamathela kuklwetshiwe.
- Isithiyo esingokomzimba: Ama-flakes agqagqene avimba umswakama, umoya-mpilo, nama-ion abolayo.
- I-Chemical passivation: I-Chromium ihlanganisa ukuncibilika kwe-zinc okunensayo kanye nokululazeka kokuziphilisa.
Izinzuzo Eziyinhloko
- Ayikho i-hydrogen embrittlement: Inqubo engeyona eye-electrolytic — iphephile kumabhawodi anamandla aphezulu eBanga lesi-8.8–10.9.
- Ukumelana nokugqwala okuphezulu: Isifutho sikasawoti samahora angu-500–1,200 (ISO 9227), 5–10x esingcono kune-zinc plating.
- Mncane & umfaniswano: 4–10 µm igcina ukulingana kwentambo kanye nejometri ye-flange. Akukho ukuthepha kabusha okudingekayo.
- Ukumelana nokushisa & ne-eco-friendly: Imelana no-250 ° C; I-Cr⁶⁺-mahhala, i-RoHS/REACH iyahambisana.
I-Coating Comparison
| Impahla | I-Dacromet | I-Zinc Plating | I-Hot-Dip Galv. |
| Isifutho sikasawoti (amahora) | 500 - 1,200 | 96 – 240 | 300 - 1,000 |
| I-Hydrogen Embrittlement | Lutho | Ubungozi (Gr. 10.9+) | Lutho |
| Ukuqina Kokunamathela | 4 – 10 µm | 5 – 25µm | 45 - 85 µm |
| I-Thread Fit Impact | Okuncane | Phansi | Okubalulekile |
| Ukumelana Nokushisa | 250°C | 200°C | 250°C |
| Ukubukeka | Silver-grey, matte | Okuluhlaza okwesibhakabhaka | Igqamile / i-spangled |
Isifinyezo
Amabhawodi e-Dacromet flange anikeza inhlanganisela efanelekile yokusebenza kahle kwemishini nokuvikela ukugqwala. I-flange ebalulekile isabalalisa umthwalo futhi yenze kube lula ukuhlanganisa, kuyilapho i-Dacromet zinc-aluminium flake coating iletha amahora angama-500-1,200 wokumelana nesifutho sikasawoti ngaphandle kokufakwa kwe-hydrogen. Lezi zibophelelo zisetshenziswa kakhulu ezimotweni, zokwakha, zamandla omoya, nasezisetshenziswa zasolwandle lapho ukubamba okuthembekile nokuqina kwesikhathi eside kubalulekile.
