La dhajiyay 2019-04-29Tiknoolajiyada Dacromet waxay leedahay faa'iidooyin taxane ah oo dheesha dhaqameedku aysan la jaan qaadi karin, waxayna si dhakhso ah u riixdaa suuqa caalamiga ah.Ka dib in ka badan 20 sano oo horumarinta joogtada ah iyo hagaajinta, tignoolajiyada Dacromet ayaa hadda samaysay nidaam daaweyn oo dhammaystiran oo dusha sare ah, kaas oo si weyn loogu isticmaalo daaweynta ka hortagga daxalka ee qaybaha birta.
Astaamaha ugu muhiimsan ee daahan cagaarka ah ee aan chrome-ka lahayn
Dhumucdiisuna: 1. Dhumucda dahaarka waa 6-12 microns, dhumucda dahaarka dusha sare waa 10-15 microns.2, jajaban anaerobic: daaweynta daahan uma baahna qajaar ama daadin.3. Ciribtirka khatarta daxalka birta ah ee labanlaaban: Ledhku waxa ay meesha ka saartaa daxalka bimetallic ee zinc-aluminium ama zinc-iron oo inta badan ku dhaca dahaarka zinc.4. Iska caabinta dareeraha: Daahanka aan noolaha ahayn wuxuu leeyahay iska caabin dareere ah oo aad u fiican.5, caabbinta kulaylka: dahaarka waxaa ku jira tiro badan oo xaashiyo bir ah, kuwaas oo noqon kara koronto.6, iska caabin daxalka Performance: tijaabada buufin cusbo 240-1200 saacadood 8, waxqabadka adhesion: ka fiican daahan zinc chromium (daahan Dacro).
Waxqabadka deegaanka ee heer sare ah: 1, ma jiro chromium: kuma jiro nooc kasta oo chromium ah (ay ku jiraan trivalent iyo hexavalent) 2, kuma jiraan biro sun ah: kuma jiraan nikkel, cadmium, rasaas, antimony iyo meerkuri.
Dahaarka cagaarka ah ee bilaa-Chrome dahaarka ka-hortagga daxalka
Saamaynta gaashaanka: 1. Budada zinc-aluminium ee qolofaysan waxay si heer sare ah u abaabushaa dhexgalka warbaahinta daxalka ah.2, Yin iyo Yang ilaalinta: zinc sida allabari anode ah si ay birta uga ilaaliso daxalka.3. Passivation: Okssaydhyada biraha waxay yareeyaan daxalka bimetallic ee zinc iyo substrates birta.4, is-bogsiin: Ogsajiinta iyo carbon dioxide ee hawada ku jira waxay la falgalaan zinc oo ku yaal dusha sare ee daahan si ay u sameeyaan zinc oxide iyo zinc carbonate.Maaddaama mugga zinc oxide iyo zinc carbonate uu ka weyn yahay isla qaddarka zinc, marka ay u guurto meesha dhaawacan, waxay awood u yeelan kartaa hagaajinta.
