Dacromet Coating vs. Kupisa-Dip Galvanizing: Ndeipi Corrosion Dziviriro Yakakodzera Kupurojekiti Yako?
2026-04-30
Corrosion ndiye muvengi akanyarara weese magadzirirwo esimbi. Kusarudza tekinoroji yakakodzera yekupfekedza kunogona kureva musiyano pakati pechisimbiso chinotora makore gumi uye chimwe chinotadza mu2. KuFujinrui, tinobatsira mainjiniya nezvikwata zvekutenga zvinhu pasi rese kuita sarudzo dzine ruzivo. Nhasi, tinoputsa maviri anowanzo kufananidzwa masisitimu ekupfeka: Dacromet uye Kupisa-Dip Galvanizing (HDG).
Musoro-kune-Musoro Kuenzanisa
| Feature | Dacromet Coating | Hot-Dip Galvanizing |
| Corrosion Resistance | 800–1,200 maawa (pfapfaidzo yemunyu) | 400-600 maawa (munyu pfapfaidzo) |
| Operating Temperature | Kusvikira ku300°C | Kusvikira ku250 ° C |
| Hydrogen Embrittlement | Hapana njodzi (kubikira-yemahara maitiro) | Ngozi ine mabhaudhi ane simba rakakwirira |
| Coating Ukobvu | 4–8 μm (yakanyanya kutetepa) | 40-80 μm (yakakora layer) |
| Thread Fit | Hapana kukanganiswa kwe thread | Kucheka zvakare shinda kunodiwa kazhinji |
| Environmental Impact | Cr6+-yemahara, eco-hushamwari | Zinc fume emissions |
| Pedzisa Chitarisiko | Sirivha-grey, yunifomu | Zinc spangle pattern |
| Best For | High-chaiyo & motokari | Structural & outdoor |
Nei Vakawanda Mainjiniya Vachisarudza Dacromet
- Superior Salt Spray Performance: Inodarika HDG ne2-3x mune isina kwayakarerekera munyu yekupfapfaidza bvunzo, ichiita kuti ive yakanakira nzvimbo dzemugungwa uye dzakanyorova.
- Hapana Hydrogen Embrittlement: Inobvisa njodzi yekukasira kutadza kwebhaudhi pane yakakwirira-simba fasteners (kirasi 10.9 uye pamusoro) - yakakosha kuchengetedza mukana.
- Precision Thread Preservation: Ultra-yakaonda coating inoita kuti mabhaudhi nenzungu zvikwane zvakakwana pasina post-yekuputira tambo rework.
- ROHS & ISO Zvinoenderana: Inosangana neEU yezvakatipoteredza zviyero. Inokodzera mota, zvemagetsi, uye misika-inonzwa kunze kwenyika.
Nguva Yekufunga Kupisa-Dip Galvanizing
HDG inoramba iri sarudzo inodhura yemabhaudhi mahombe ezvimiro uye mapurojekiti ekunze ezvivakwa uko kutenderera kwakanyanyisa kwecorrosion hakusi iko kwekutanga kunetseka. Iyo inokunda muhuwandu hwekushandisa uko gobvu zinc layer inopa kuchengetedzwa kwemichina. Nekudaro, kune chaiyo yekumisikidza uye kuchengetedza-yakakosha maapplication, Dacromet iri kuwedzera mhinduro yakasarudzika.
