Kukula kwaukadaulo kwa Dacromet (zopaka za zinc chrome)

Adalemba pa 2018-12-28Dacromet ndimasulidwe achi China a DACROMETR, omwe amadziwikanso kuti zinc chrome film, Dak rust, Dakman, etc., ndipo adzatchedwa "zinc chrome coating" muyeso wa Dacromet waku China.), lomwe limatanthauzidwa kuti: "Zopaka zotsutsana ndi dzimbiri zokhala ndi scaly zinki ndi zinki chromate monga zigawo zazikulu za kuviika, kupaka kapena kupopera madzi opangidwa ndi zinki-chromium pamwamba pa zitsulo kapena zigawo zikuluzikulu.Ukadaulo wa Dacromet unapangidwa ndi anthu aku America ndipo ndi mankhwala opaka zitsulo ofanana ndi electro-galvanizing.

Chophimba cha Dacromet chili ndi mawonekedwe amtundu wa siliva-imvi ndipo chimakhala ndi 80% zopyapyala za zinc mu zokutira.Aluminiyamu pepala, ena onse ndi chromate, ali ndi ntchito zabwino kwambiri, monga kukana dzimbiri wamphamvu: 7 mpaka 10 kuposa electrogalvanizing;anaerobic brittle;makamaka oyenerera mbali zamphamvu kwambiri, monga zomangamanga zapansi panthaka Maboti amphamvu kwambiri;kukana kutentha kwakukulu;kutentha kosagwira kutentha 300 ° C.

Kuonjezera apo, ilinso ndi ubwino wokwanira kwambiri, kumatira kwakukulu, kuchepetsa kukangana kwakukulu, kukana kwa nyengo, kukhazikika kwa mankhwala komanso kusawononga chilengedwe.

M'mayiko otukuka, teknoloji ya Dacromet metal surface anti-corrosion yakhala ikugwiritsidwa ntchito ngati njira yothetsera kutupa kwazinthu zambiri zachikhalidwe monga electroplating, otentha dip galvanizing, electroplating cadmium, zinc-based alloy plating, phosphating, ndi zina zotero. kwenikweni amachepetsa kuipitsa chilengedwe.

Chifukwa cha ntchito yake yosavuta, kupulumutsa mphamvu, komanso kuwononga chilengedwe chochepa, teknoloji ya Dacromet ingapewe ubwino wa zinki zachikhalidwe za electroplating ndi teknoloji yotentha ya dip galvanizing monga hydrogen embrittlement.Chifukwa chake, yakhala ikugwiritsidwa ntchito kwambiri kuyambira zaka za m'ma 1970, makamaka m'makampani opanga magalimoto m'maiko otukuka monga United States ndi Japan, ndipo idakulitsidwa mpaka kumanga, zankhondo, zomanga zombo, njanji, mphamvu yamagetsi, zida zapanyumba, zaulimi. makina, migodi, milatho, etc. munda.
