I-Dacromet Flange Bolts-Anti-Corrosion Flange Fasteners kunye neZinc-Aluminium Flake Coating
2026-07-15
Iibholiti ze-Dacromet ze-flange zidibanisa uyilo lokusabalalisa umthwalo wentloko ye-flange kunye nokukhusela okuphezulu kwe-corrosion ye-zinc-aluminium flake coating. I-flange edibeneyo iphelisa imfuno ye-washer eyahlukileyo, ngelixa i-Dacromet yokugqoka ihambisa i-500-1,200 iiyure zokumelana nokutshiza ityuwa ngaphandle kwe-hydrogen embrittlement - okwenza ezi zibophelelo zilungele i-automotive, ukwakhiwa, kunye nezicelo zesakhiwo sangaphandle.
Icandelo loku-1 - Isishwankathelo seFlange Bolt
Yintoni iBolt yeFlange?
Ibholithi yeflange yibhawunti yehex enentloko edityanisiweyo ene-washer efana neflange emazantsi entloko. I-flange isasaza umthwalo we-clamping kwindawo ebanzi, ukunciphisa uxinzelelo lwangaphezulu kwizinto ezidibeneyo kunye nokuthintela umonakalo kwiindawo ezithambileyo okanye ezipeyintiweyo. Oku kuphelisa imfuno yewasha eflethi eyahlukileyo, ukwenza lula ukudibanisa kunye nokunciphisa inani leenxalenye.
Iimpawu eziphambili zoYilo
I-Flange edibeneyo: Ukusasaza amandla okubamba kwindawo enkulu kunentloko ye-hex eqhelekileyo, ukunciphisa uxinzelelo kunye nokuthintela ukujongwa komphezulu.
Ukhetho olulungelelanisiweyo: I-Serrated flange underside iluma kumphezulu wokukhwelana, inika ukuxhathisa okwakhelwe ngaphakathi kokuchasa ukukhulula ngaphandle kwezinto ezongezelelweyo zokutshixa.
Imilinganiselo esemgangathweni: Yenziwe kwi-DIN 6921, ISO 4162, okanye i-GB/T 5787, iqinisekisa ukutshintshiselana kuwo wonke amatyathanga okubonelela ngehlabathi.
Amabanga aphezulu kakhulu: Ifumaneka kwiklasi yepropathi 8.8 kunye ne-10.9, ifanelekile kwizakhiwo kunye nezicelo zokuthwala umthwalo.
Iinkcukacha
| Inkcazo | Ixabiso | Inkcazo | Ixabiso |
| Umgangatho | DIN 6921 / ISO 4162 / GB/T 5787 | Umsonto | I-Metric M6 – M20 |
| Iklasi yePropati | 8.8 / 10.9 | Uhlobo lweNtloko | I-Hex ene-flange edibeneyo |
| Ukwaleka | I-Dacromet (iflake ye-zinc-aluminiyam) | Ukutyeba kokutyabeka | 4 – 10 µm |
| Isitshizi seTyuwa | 500 – 1,200 iiyure (ISO 9227) | Izinto eziphathekayo | Intsimbi yekhabhoni / intsimbi yealloyi |
| UKhetho lweSerrated | I-Serrated / non-serrated flange | Okusingqongileyo | I-Cr⁶⁺-simahla, i-RoHS iyahambelana |
Icandelo 2 - iTekhnoloji yokuCoating yeDacromet
I-Dacromet (达克罗) yinkqubo esekwe emanzini, engeyiyo eye-electrolytic yonyango ebeka ifilimu ebhityileyo ye-zinc kunye neeflakes ze-aluminium ezidityaniswe yi-inorganic chromium ikhompawundi. Isetyenziswe ngenkqubo ye-dip-spin-cure, inika iileya ezininzi zokukhusela i-corrosion ngaphandle kokuzisa i-hydrogen kwintsimbi - inzuzo ebalulekileyo kwi-fasteners ephezulu.
Inkqubo yoKhuseleko loMhlwa
Ukhuseleko lwedini: I-zinc flakes i-corrode ngokukhethekileyo ukukhusela i-substrate yensimbi, nangona xa i-coating ikrwela.
Umqobo ngokwasemzimbeni: Iiflake ze-zinc-aluminiyam ezigqwesileyo zidala indlela eyingozi ethintela ukufuma, ioksijini kunye neeyoni ezibolayo.
Ukwenziwa kweekhemikhali: Iikhompawundi zeChromium zenza umaleko we-passive ocothisa ukunyibilika kwe-zinc kwaye ibonelela ngokuziphilisa kwimikrwelo emincinci.
Izinto eziluncedo eziphambili kwiiBolts zeFlange
Akukho embrittlement yehydrogen: Inkqubo ye-non-electrolytic - ikhuselekile kwiBanga le-8.8-10.9 i-high-strength flange bolts apho i-electroplating inqatshelwe.
Mncinci & iyunifomu: I-4–10 µm yokugquma igcina ukulingana kwemisonto kunye nejometri yeflange. Akukho ukucofa kwakhona kwamandongomane afunekayo.
500–1,200 iiyure zokutshiza ngetyuwa: Amaxesha ama-5-10 angcono kune-zinc plating yesiqhelo, ilungele ukuvezwa kwangaphandle kwexesha elide.
Ukumelana nobushushu: Imelana nenkonzo eqhubekayo ukuya kuthi ga kwi-250°C — ilungele i-injini bay kunye ne-exhaust-fasteners ezikufuphi.
Iyahambelana nendalo: I-Cr⁶⁺-simahla, i-RoHS kunye ne-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 | 4 – 10 µm | 5 – 25 µm | 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 |
Isitshizi setyuwa ngokwe-ISO 9227 NSS. Umngcipheko we-Hydrogen embrittlement usebenza kwiifasteners ze-electroplated zeBanga le-10.9 nangaphezulu.
Isishwankathelo
I-Dacromet flange bolts inika indibaniselwano enyanzelekileyo yokusebenza komatshini kunye nokukhusela ukubola. I-flange edibeneyo yenza lula ukuhlanganisana ngelixa uhambisa umthwalo ngokulinganayo, kwaye i-Dacromet zinc-aluminium flake coating ihambisa iiyure ezingama-500-1,200 zokuxhathisa ityuwa ngaphandle kwe-hydrogen embrittlement. Ezi zibophelelo zisetyenziswa ngokubanzi kwiimoto, ulwakhiwo, amandla omoya, kunye nezicelo zaselwandle apho zombini ukusebenza okuthembekileyo okubambekayo kunye nokuqina kwexesha elide kubalulekile.
