I whakairihia ki runga 2019-02-12Ko te silicone me te nano-powder i tukinotia ki te nano-dispersion ka marara ki roto i te tini o te resin cross-linked polymerized composite resins, a i muri i te whakarereketanga, ka taea te tango i te paura zinc me te paura konumohe kia kore he chromium, waikawa- ātete, me te konupora konupora chromium-kore otinga Dacromet me nga painga o te parenga rehu tote, te tiaki i te taiao, te kiriata paninga angiangi, te pai o te rangi me te awangawanga paanga.Zhang Shuyong et al.tāpirihia te paura konutea, te paura konumohe, te wai whakakorehia, te dispersant (decadiol polyoxyethylene ether, te cetyl polyoxyethylene ether ranei), te phosphate (te konumohe hydroxide me te 85% te waikawa phosphoric i roto i te waahanga), te whakamaera (te wai-wairewa methyl cellulose ether or hydroxypropyl methyl cellulose ether), tripolyphosphate, polymerization initiator (35% hydrogen peroxide and / or potassium permanganate), pH regulator (konutea waikura, oxidation Calcium or calcium hydroxide) me te awhina kiriata (polyethylene glycol) ka konatunatua kia rite ki tetahi ōwehenga, ka oho riterite, ka ko te pH. ka whakahaeretia i te 3.5 ki te 5.5 kia whiwhi i te wai whakakikorua Dacromet kore-chromium.He pai te taiao me te kore parahanga te tenenga.Ko te mahi waikura ko te 7 ki te 10 nga wa teitei ake i tera o te electrogalvanized, a he pai ano hoki nga painga o te uruhanga teitei, te whakaheke o te waku, me te kaha o te rangi.Zhu Chengfei et al.Te paura konutea, te paura konumohe, te makuku me te marara (te waipiro, te polyalcohol ranei), te kaihoko whakawhiti (waikawa phytic), te aukati waikura (konutai molybdate), te wai, te kaihoko hanga kiriata (konupora acetate, te konupora konupora, te konupora chloride ranei), te awhina kiriata (silane). kaihoko hono), hanga awhina (waikawa boric waikawa succinic ranei) me te thickener (hydroxymethyl cellulose hydroxyethyl cellulose ranei) kua rite i runga i tetahi ōwehenga ki te whiwhi kore Ki te whakaritea ki te toi o mua, te wai paninga chromium dacrox he pai o te kore parahanga, kahore parahanga, iti te kohi pūngao me te pai kākahu ātete.
Ma te whakamahi i te waikawa phosphoric hei herenga me te kaihoko haere, he awhina te whenua onge, konumohe paura, paura konutea, 85% waikawa phosphoric, konumohe hydroxide, hydrogen peroxide, calcium oxide, cetyl polyoxyethylene ether, hydroxypropyl cellulose ether, ammonium cerium nitrate me te ammonium nitrate. kia rite ki tetahi ōwehenga, oho rite, me te pH te mana ki te 5.5, ki te whiwhi i te chromium-free Dacromet paninga wai ki pai te waikura ātete.Ko nga rangahau e whakaatu ana ko te taapiri o te tote strontium whenua onge ka whakaiti i te paninga.Ko te waikura o te paparanga he pai te aukati i te waikura ki te paninga Dacromet.
