Kuthunyelwe ku 2019-02-12I-silicone kanye ne-nano-powder ephathwa nge-nano-dispersion ihlakazeka ebuningini bezinhlaka eziyinhlanganisela ye-polymerized cross-linked cross-linked, futhi ngemva kokushintshwa, impushana ye-zinc kanye ne-aluminium powder ingatholwa ukuze ibe ne-chromium-free, acid- ukumelana, kanye nesixazululo se-Magnesium alloy chromium-free Dacromet esinezinzuzo zokumelana nesifutho sikasawoti, ukuvikelwa kwemvelo, ifilimu encane yokumboza, ukumelana nesimo sezulu esihle kanye nokumelana nomthelela.UZhang Shuyong et al.wanezela i-zinc powder, i-aluminium powder, amanzi e-deionized, i-disperant (i-decadiol polyoxyethylene ether noma i-cetyl polyoxyethylene ether), i-phosphate (i-aluminium hydroxide no-85% we-phosphoric acid ngokulingana), i-Thickener (i-methyl cellulose ether encibilikayo emanzini noma i-hydroxypropyl cellulose sodium cellulose), i-tripolyphosphate, i-polymerization initiator (35% ye-hydrogen peroxide kanye / noma i-potassium permanganate), isilawuli se-pH (i-zinc oxide, i-oxidation I-Calcium noma i-calcium hydroxide) nosizo lokuthwebula (i-polyethylene glycol) ixutshwa ngokwesilinganiso esithile, inyakaziswa ngokulinganayo, futhi i-pH kulawulwa ku-3.5 kuya ku-5.5 ukuze kutholwe uketshezi lwe-Dacromet olungena-chromium.Lokhu okusunguliwe kuyayihambisana nemvelo futhi akungcolisi.Ukusebenza kokugqwala kuphakeme ngokuphindwe ka-7 kuya kweziyi-10 kunokwe-electrogalvanized, futhi kunezinzuzo zokungena okuphezulu, ukunciphisa ukushwibeka okuphezulu, nokumelana nesimo sezulu esiphezulu.UZhu Chengfei et al.Impushana ye-zinc, i-aluminium powder, i-ejenti yokumanzisa kanye ne-dispersing (utshwala noma i-polyalcohol), i-passivating agent (phytic acid), i-corrosion inhibitor (i-sodium molybdate), amanzi, i-ejenti eyenza ifilimu (i-manganese acetate, i-manganese nitrate noma i-Manganese chloride), usizo lokuqopha (silane). i-ejenti yokuhlanganisa), insiza yokwakha (i-boric acid noma i-succinic acid) kanye ne-thickener (i-hydroxymethyl cellulose noma i-hydroxyethyl cellulose) ilungiswa ngokwesilinganiso esithile ukuze ingatholi lutho Uma kuqhathaniswa nobuciko bangaphambili, uketshezi oluhlanganisa i-chromium dacrox lunezinzuzo zokungangcolisi, akukho ukungcola, ukusetshenziswa kwamandla okuphansi kanye nokumelana nokugqokwa okuhle.
Isebenzisa i-phosphoric acid njenge-binder kanye ne-passivating agent, umhlaba ongavamile uyisisizi, i-aluminium powder, i-zinc powder, i-85% phosphoric acid, i-aluminium hydroxide, i-hydrogen peroxide, i-calcium oxide, i-cetyl polyoxyethylene ether, i-hydroxypropyl cellulose ether, i-ammonium cerium nitrate ne-ammonium nitrate ngokwesilinganiso esithile, inyakaziswa ngokulinganayo, futhi i-pH ilawulwa ibe ngu-5.5, ukuze kutholwe uketshezi lwe-Dacromet olungena-chromium olunoketshezi oluhle kakhulu olumelana nokugqwala.Ucwaningo lubonisa ukuthi ukungezwa kosawoti ongavamile we-earth strontium kunciphisa ngempumelelo ukunamathela.I-corrosion current yongqimba inomphumela omuhle wokuvimbela ukugqwala ku-Dacromet coating.
