Adalemba pa 2018-09-10Kanema wa Dacromet ali ndi zinki zabwino zachitsulo, aluminiyamu ufa ndi chromate.Ndi zokutira zachitsulo za matt silver-gray zomwe zimapezedwa pambuyo potikita ndi kuphika.Amatchedwanso kuti zinc flake coating.Ngakhale zokutira za Dacromet zimawoneka ngati zosanjikiza zachikhalidwe zama electrogalvanized, zokutira za Dacromet zili ndi zabwino zomwe zigawo zachikhalidwe zokhala ndi zinc sizingafanane:
1) Palibe hydrogen brittle.Njira ya Dacromet imakhala yopanda asidi ndipo ilibe vuto la hydrogen permeation.Ndikoyenera makamaka ku ma bolts amphamvu kwambiri ndi ziwalo zotanuka pambuyo pochiritsa pa kutentha kwakukulu.
2) Njirayi ndiyopanda kuipitsa.Njira yochiritsira ya Dacromet imakhala yopanda zinyalala zitatu, chifukwa chake imayambitsa pafupifupi kuwononga chilengedwe.
3) Kugonjetsedwa kwambiri ndi dzimbiri.Kanema wa Dacromet ndi woonda kwambiri, koma zotsatira zake zoteteza pazigawo zachitsulo ndi 7-10 nthawi ya electroplated zinc wosanjikiza wa makulidwe omwewo.Chophimba cha Dacromet chopezedwa ndi kupaka katatu ndi kuphika katatu chimakhala ndi kusalowerera ndale mchere kutsitsi kuposa 1000h.
4) High permeability ndi kutentha kwambiri kukana.Njira yochizira ya Dacromet imayikidwa kapena yokutidwa, ndipo palibe vuto la kupukutira kosauka komanso kuthekera kwakuya kwakuya chifukwa cha zovuta zogwirira ntchito, ndipo zokutira zitha kugwiritsidwa ntchito mosalekeza kwa nthawi yayitali mu malo a 250 digiri, komanso dzimbiri. kukana kumasungidwa, mawonekedwe samakhudzidwa.
5) Electrochemical dzimbiri kukana kwa zinc-aluminium bimetal.Zinki zambiri zimagwira ntchito bwino ndi aluminiyamu kapena magawo achitsulo kuti apange ma microbattery a bimetallic, ndipo ma flakes a aluminiyumu mu zokutira Dacromet amachotsa chodabwitsa ichi.
6) Kuthekera kolimba kwambiri koyambiranso.Chophimba cha Dacromet chimakhala chokhazikika bwino ndipo chimatha kujambulidwa ndi penti yachiwiri pamwamba pa chogwirira ntchito pambuyo pokonza.
