I-Dacromet Coating vs. Hot-Dip Galvanizing: Yikuphi Ukuvikela Ukugqwala Okulungele Iphrojekthi Yakho?
2026-04-30
Ukugqwala kuyisitha esithule sazo zonke izakhiwo zensimbi. Ukukhetha ubuchwepheshe bokugqoka obufanele kungasho umehluko phakathi kwesiqhoboshi esihlala iminyaka engu-10 naleyo ehlulekayo kokungu-2. E-Fujinrui, sisiza onjiniyela namathimba okuthenga izinto emhlabeni wonke enze izinqumo ezinolwazi. Namuhla, sihlukanisa amasistimu wokuhlanganisa amabili avame ukuqhathaniswa: I-Dacromet futhi I-Hot-Dip Galvanizing (HDG).
Ukuqhathanisa kwekhanda nekhanda
| Isici | I-Dacromet Coating | I-Hot-Dip Galvanizing |
| Ukumelana Nokugqwala | 800–1,200 amahora (isifutho sikasawoti) | Amahora angu-400-600 (isifutho sikasawoti) |
| Izinga Lokushisa Lokusebenza | Kufika ku-300°C | Kufika ku-250°C |
| I-Hydrogen Embrittlement | Abukho ubungozi (inqubo yokungabhaki) | Ingozi enamabhawodi anamandla |
| Ukuqina Kokunamathela | 4–8 μm (umncane kakhulu) | 40–80 μm (ungqimba olugqinsi) |
| I-Thread Fit | Akukho ukuphazamiseka kwentambo | Ukusika kabusha intambo ngokuvamile kuyadingeka |
| Umthelela Wezemvelo | I-Cr6+-mahhala, i-eco-friendly | Ukukhishwa kwentuthu ye-Zinc |
| Qeda Ukubukeka | Isiliva-mpunga, umfaniswano | Iphethini ye-zinc spangle |
| Kuhle kakhulu | Ukunemba okuphezulu nezimoto | Okwesakhiwo nangaphandle |
Kungani Onjiniyela Abengeziwe Bakhetha I-Dacromet
- Ukusebenza kwe-Superior Salt Spray: Idlula i-HDG ngo-2–3x ekuhlolweni kwesifutho sikasawoti esimaphakathi, okuyenza ilungele izindawo zasolwandle nezinomswakama ophezulu.
- Ayikho i-Hydrogen Embrittlement: Iqeda ubungozi bokungaphumeleli kwebhawodi kungazelelwe kuzixhumi zamandla aphezulu (ikilasi 10.9 nangaphezulu) - inzuzo ebalulekile yokuphepha.
- Ukulondolozwa Kwentambo Eqondile: I-Ultra-coating coating iqinisekisa ukuthi amabhawodi namantongomane alingana kahle ngaphandle kokusebenza kabusha kwentambo yangemuva kokunameka.
- I-ROHS & ISO iyahambisana: Ihlangabezana nezindinganiso zemvelo ze-EU. Ifanele izimakethe zezimoto, ze-elekthronikhi, nezingazweli ukuthekelisa.
Nini Yokucatshangelwa I-Hot-Dip Galvanizing
I-HDG isalokhu iyisinqumo esingabizi kakhulu samabhawodi amakhulu esakhiwo kanye namaphrojekthi wengqalasizinda yangaphandle lapho imijikelezo yokugqwala ngokweqile kungeyona into ekhathaza kakhulu. Iphumelela ezinhlelweni eziningi lapho ungqimba oluqinile lwezinc luhlinzeka ngokuvikeleka komshini. Kodwa-ke, kuma-fasteners anembayo nezinhlelo zokusebenza ezibucayi zokuphepha, i-Dacromet iya ngokuya iyisixazululo esithandwayo.
