Fa'asalalau ile 2019-02-12O le silicone ma le nano-powder ua togafitia i le nano-dispersion o loʻo faʻasalalauina i totonu o le tele o resini polymerized composite resins e fesoʻotaʻi faʻasalalau, ma a maeʻa ona suia, e mafai ona maua le paʻu zinc ma le paʻu alumini e maua ai le chromium-free, acid- tetee, ma le Magnesium alloy chromium-free Dacromet solution faʻatasi ai ma le lelei o le faʻafefe o le masima, puipuiga o le siosiomaga, ata tifaga manifinifi, lelei le tau ma le aʻafiaga.Zhang Shuyong et al.faʻaopoopo le paʻu zinc, paʻu alumini, vai faʻafefeteina, faʻasalalau (decadiol polyoxyethylene ether poʻo le cetyl polyoxyethylene ether), phosphate (alumini hydroxide ma le 85% phosphoric acid i le faʻatusatusaga), Thickener (vai-soluble methyl cellulose ether po o le sodium hydroxypropyl methyl cellulose ether), tripolyphosphate, polymerization initiator (35% hydrogen peroxide ma / poʻo le potassium permanganate), pH regulator (zinc oxide, oxidation Calcium poʻo le calcium hydroxide) ma le fesoasoani ata (polyethylene glycol) e faʻafefiloi e tusa ai ma se fua faatatau, faʻafefe tutusa, ma le pH pulea i le 3.5 i le 5.5 e maua ai se chromium-free Dacromet coating vai.O le mea fou fou e faauo i le siosiomaga ma e leai se filogia.O le faʻaleagaina o le 7 i le 10 taimi e sili atu nai lo le eletise eletise, ma e iai foʻi le lelei o le maualuga o le faʻaogaina, faʻaitiitia o le vevesi, ma le maualuga o le tau.Zhu Chengfei et al.Zinc paʻu, paʻu alumini, susu ma faʻasalalau mea (ava malosi poʻo le polyalcohol), sui faʻafefe (phytic acid), inhibitor corrosion (sodium molybdate), vai, mea faʻapipiʻi ata (manganese acetate, manganese nitrate poʻo Manganese chloride), fesoasoani ata (silane). so'o fa'afeso'ota'i), fau fesoasoani (boric acid po'o succinic acid) ma mafiafia (hydroxymethyl cellulose po'o le hydroxyethyl cellulose) ua saunia e tusa ai ma se fua faatatau patino e le maua ai Pe a faatusatusa i le faatufugaga muamua, o le chromium dacrox coating vai ei ai le lelei o le leai o se filogia, leai se faʻaleagaina, maualalo le faʻaaogaina o le malosi ma le lelei o le ofuina.
O le faʻaaogaina o le phosphoric acid e fai ma mea faʻapipiʻi ma sui faʻasaʻo, o le eleele e le masani ai o se fesoasoani, paʻu alumini, paʻu zinc, 85% phosphoric acid, alumini hydroxide, hydrogen peroxide, calcium oxide, cetyl polyoxyethylene ether, hydroxypropyl cellulose ether, ammonium cerium nitrate ma ammonium nitrate ua faʻafefiloi. e tusa ai ma se fua faatatau patino, faʻavevesi tutusa, ma o le pH o loʻo pulea i le 5.5, e maua ai se chromium e leai se totogi o le Dacromet faʻapipiʻi vai ma le faʻafefeteina lelei.O suʻesuʻega ua faʻaalia ai o le faʻaopopoina o le masima strontium e seasea ona faʻaitiitia le faʻafefe.O le faʻaleagaina o loʻo i ai i le taimi nei o loʻo i ai se aafiaga faʻafefe lelei i luga o le paʻu o le Dacromet.
