Adalemba pa 2019-04-29Ukadaulo wa Dacromet uli ndi zabwino zingapo zomwe plating zachikhalidwe sizingafanane, ndipo zimakankhira mwachangu kumsika wapadziko lonse lapansi.Pambuyo pa zaka zoposa 20 zachitukuko ndi kukonzanso kosalekeza, teknoloji ya Dacromet tsopano yapanga dongosolo lathunthu la mankhwala pamwamba, lomwe limagwiritsidwa ntchito kwambiri pochiza zitsulo zazitsulo.
Zinthu zazikulu za zokutira zobiriwira zopanda chrome
Makulidwe: 1. Makulidwe a zokutira ndi 6-12 microns, ndipo makulidwe a zokutira ndi zokutira pamwamba ndi 10-15 microns.2, anaerobic Chimaona: ❖ kuyanika mankhwala sikutanthauza pickling kapena plating.3. Kuthetsa chiwopsezo cha kuwononga zitsulo ziwiri: Mtovu umachotsa zinc-aluminiyamu kapena zinc-iron zomwe zimachitika nthawi zambiri mu zokutira za zinki.4. Kukaniza zosungunulira: Kupaka kwachilengedwe kumakhala ndi kukana kosungunulira bwino kwambiri.5, kukana kutentha: ❖ kuyanika kumakhala ndi mapepala ambiri azitsulo, omwe amatha kukhala oyendetsa magetsi.6, kukana kwa dzimbiri Magwiridwe: mayeso opopera mchere 240-1200 maola 8, ntchito yomatira: kuposa zokutira zinki chromium (zopaka za Dacro).
Kuchita bwino kwa chilengedwe: 1, palibe chromium: ilibe mtundu uliwonse wa chromium (kuphatikiza trivalent ndi hexavalent) 2, ilibe zitsulo zapoizoni: ilibe faifi tambala, cadmium, lead, antimony ndi mercury.
Njira yothanirana ndi dzimbiri yobiriwira yopanda chrome
Chitetezo champhamvu: 1. Ufa wa scaly zinc-aluminiyamu umalinganiza bwino kulowa kwa zowononga media.2, yin ndi yang chitetezo: zinki ngati nsembe ya anode kuteteza chitsulo kuti chisawonongeke.3. Passivation: Metal oxides amachepetsa dzimbiri la bimetallic la nthaka ndi chitsulo.4, kudzichiritsa: mpweya ndi carbon dioxide mu mlengalenga amachita ndi zinki pamwamba pa zokutira kupanga zinc oxide ndi zinc carbonate.Popeza voliyumu ya nthaka okusayidi ndi nthaka carbonate ndi wokulirapo kuposa kuchuluka kwa nthaka, pamene amasamukira ku malo owonongeka, akhoza Kuti kwenikweni kukonza.
Kuti mudziwe zambiri za Dacromet, chonde tcherani khutu ku Changzhou Junhe Technology:
