E ngotsoe ka 2016-12-22Hoa tsebahala hore Dacromet ke tharollo ea metsi e qhalakaneng e nang le zinki flake, aluminium flake le li-additives.Lisebelisoa ka mor'a ho qoelisoa le ho fafatsa, ho phekola 20min ho 80 ℃ ka sebōping sa ho futhumatsa pele, 30min ho 300 ℃ ha ho folisa sebōpi.Etsa hore hexavalent chromium e ne e le joala ba adipic le phokotso ea manyolo hore e be mokelikeli oa ho roala ha dacromet ha e qhale ka metsing.
Ho lokela ho hlokomeloe hore phokotso ea chromium e hexavalent ho chromium e trivalent le trivalent chromium oxidation ho chromium e hexavalent ke ts'ebetso e ka khutlisoang morao.Ka hona, ka har'a sesebelisoa se sirelelitsoeng, chromium e trivalent e tla tsoelapele ho ba oxidized ho chromium e hexavalent, 'me chromium ea hexavalent ke carcinogen, kahoo ho kopana ho tla tlisa kotsi bophelong.Ka hona, tharollo ea setso e nang le chromium ha e tsoe ka ho feletseng, ha feela ho na le chromium e nang le hexavalent, e tla ba le tšusumetso e itseng tikolohong le bathong, ka hona, ho tsebahala ha Dacromet ea mahala ea chrome hoa hlokahala.
Ha matsapa a naha a ts'ireletso ea tikoloho a ntse a tsoela pele ho matlafala, bahlahisi ba bangata ba likarolo tsa likoloi ba hloka likarolo tse koahetsoeng ka chrome tsa mahala tsa dacromet.Ebile e ntlafalitse litekanyetso tsa tekheniki tsa chrome tsa mahala tsa dacromet.Joalo ka Volkswagen GMW3359, GM7111M joalo-joalo.
Chrome ea mahala Dacromet e batla haholo lintho tse ling ho e-na le chromic acid passivation le bonding.Ho roala ha Chrome mahala Dacromet haholo-holo ho sebelisa silicon ea tlhaho, silicon ea inorganic, molybdate, tungstate, phosphate joalo ka binder, ts'ebeliso e ts'oanang ea scaly zinc / aluminium flake e le karolo ea mantlha ea ho tlatsa, le ka letoto la seal Post-kalafo, ho fihlela katleho e ts'oanang. khanyetso ea kutu e nang le chromium e nang le Dacromet coating.
Theknoloji ea mahala ea Chrome ea Dacromet ha e na molemo feela oa theknoloji ea chromium-dacromet, empa hape le ho tloha ho pente ea ho lokisetsa, ho roala, filimi, ho roala ka boeona ha e na chromium ea hexavalent ka ho feletseng, kutloisiso ea 'nete ea ho phethahala ha botala bo se nang chefo bo se nang kotsi.Ho ea ka pono ea tikoloho, sebakeng sa lefats'e sa chrome mahala Dacromet sebakeng sa chrome dacromet tataiso e akaretsang e ke ke ea fetoha, e tla tlisa potoloho e ncha ea lefapha la thekenoloji ea anti-corrosion ea phetoho ea tikoloho.
