Iibholiti zeDacromet Flange

Iibholiti zeDacromet Flange
I-Anti-Corrosion Flange Fasteners kunye ne-Zinc-Aluminium Flake Coating
Iibholiti ze-Dacromet flange zidibanisa uyilo lwentloko ye-flange ehambisa umthwalo kunye ne-Dacromet zinc-aluminium flake coating. I-flange edibeneyo ithatha indawo ye-washer eyahlukileyo, ngelixa i-Dacromet yokugqoka ihambisa iiyure ze-500-1,200 zokumelana nokutshiza ityuwa ngaphandle kwe-hydrogen embrittlement - ilungele iimoto, ukwakhiwa, kunye nezicelo zaselwandle.
Icandelo 1 - I-Flange Bolt
Ibholithi yeflange yibhawudi yentloko yehex ene-washer edibeneyo efana neflange kwisiseko sentloko. I-flange isasaza umthwalo we-clamping kwindawo ebanzi, ukunciphisa uxinzelelo oluphezulu kunye nokuthintela umonakalo kwizinto ezixhunyiwe. Oku kuphelisa imfuno yewasha eyahlukileyo, indibano elula.
Iimpawu eziphambili
- Ukuhanjiswa komthwalo: I-Flange isasaza i-clamping force, inciphisa ukuthwala uxinzelelo ukuya kuthi ga kwi-50% xa kuthelekiswa neebholiti ze-hex eziqhelekileyo.
- Ukuchasana nokukhulula: Inketho ye-Serrated flange ibonelela ngokumelana nokungcangcazela ngaphakathi ngaphandle kokutshixa iiwasha.
- Imigangatho: I-DIN 6921 / ISO 4162 / GB/T 5787; M6–M20; IBakala 8.8 kunye ne-10.9 nge-ISO 898-1.
- Izixhobo: Intsimbi yeCarbon (iBanga le-8.8) okanye i-low-alloy steel (iBanga le-10.9), icinyiwe kwaye inomsindo.
Icandelo 2 - I-Dacromet Coating
I-Dacromet iyisiseko samanzi, i-non-electrolytic coating of overlapping zinc kunye ne-aluminium flakes ehlanganiswe yi-chromium compounds. Isetyenziswe ngemijikelo ye-dip-spin-cure kwi-280-300 ° C, inika ukhuseleko lwe-corrosion yemigangatho emithathu ngaphandle kwe-hydrogen embrittlement.
Inkqubo yoKhuseleko
- Ukhuseleko lwedini: I-zinc flakes i-corrode ngokukhethekileyo ukukhusela intsimbi, nangona xa i-coating ikrwela.
- Umqobo ngokwasemzimbeni: Iiflakes eziwelanayo zivimba ukufuma, ioksijini, kunye neeyoni ezidlayo.
- Ukwenziwa kweekhemikhali: I-Chromium idibanisa ukunyibilika okucothayo kwe-zinc kunye nokuziphilisa imikrwelo emincinci.
Izinto Eziluncedo Ezingundoqo
- Akukho embrittlement yehydrogen: Inkqubo ye-non-electrolytic - ikhuselekile kwiBakala 8.8-10.9 iibholiti zamandla aphezulu.
- Uxhathiso oluphezulu lokutya: 500–1,200 hrs isitshizi setyuwa (ISO 9227), 5–10x ingcono kune-zinc plating.
- Mncinci & iyunifomu: I-4–10 µm igcina ukulingana komsonto kunye nejometri yeflange. Akukho ukucofa kwakhona okufunekayo.
- Ukumelana nobushushu kunye ne-eco-friendly: Ukumelana ne-250 ° C; I-Cr⁶⁺-simahla, i-RoHS/REACH iyahambelana.
Uthelekiso lokwaleka
| Ipropati | Dacromet | Ukufakwa kweZinc | Hot-Dip Galv. |
| Isitshizi seTyuwa (iiyure) | 500 - 1,200 | 96 – 240 | 300 - 1,000 |
| I-Hydrogen Embrittlement | Akukho nanye | Umngcipheko (Gr. 10.9+) | Akukho nanye |
| Ukutyeba kokutyabeka | 4 – 10 µm | 5 – 25µm | 45 – 85 µm |
| Umsonto Fit Impact | Ubuncinci | Phantsi | Kubalulekile |
| Ukumelana nobushushu | 250°C | 200°C | 250°C |
| Imbonakalo | Isilivere-ngwevu, imatte | Blue-white | Ekhanyayo / egobileyo |
Isishwankathelo
Iibholiti ze-Dacromet flange zibonelela ngodibaniso olufanelekileyo lobuchule bomatshini kunye nokukhuselwa komhlwa. I-flange edibeneyo isasaza umthwalo kwaye yenza lula ukuhlanganisana, ngelixa i-Dacromet zinc-aluminium flake coating ihambisa iiyure ezingama-500-1,200 zokumelana nokutshiza ityuwa ngaphandle kwe-hydrogen embrittlement. Ezi zibophelelo zisetyenziswa kakhulu kwiimoto, kulwakhiwo, kumandla omoya, nakwizicelo zaselwandle apho ukubambelela okuthembekileyo kunye nokuqina kwexesha elide kubalulekile.
