Yakatumirwa pa 2019-02-12Iyo silicone uye nano-hupfu yakabatwa ne nano-kupararira inoparadzirwa muhuwandu hwe resin-yakabatanidzwa polymerized composite resin, uye mushure mekugadziriswa, zinc poda uye aluminium poda inogona kuwanikwa kuti iine chromium-isina, acid- isingadziviriri, uye Magnesium alloy chromium-isina Dacromet mhinduro ine zvakanakira zvemunyu wekupfapfaidza kuramba, kuchengetedzwa kwezvakatipoteredza, nhete yekuputira firimu, yakanaka yemamiriro ekunze kuramba uye kukanganisa kupikisa.Zhang Shuyong et al.yakawedzera zinc poda, aluminium poda, mvura yakasvibiswa, dispersant (decadiol polyoxyethylene ether kana cetyl polyoxyethylene ether), phosphate (aluminium hydroxide uye 85% phosphoric acid muchikamu), Thickener (inonyungudika nemvura methyl cellulose ether kana hydroxypropyl methyl cellulose sodium), tripolyphosphate, polymerization initiator (35% hydrogen peroxide uye / kana potassium permanganate), pH regulator (zinc oxide, oxidation Calcium kana calcium hydroxide) uye rubatsiro rwekudhirowa (polyethylene glycol) inosanganiswa zvichienderana nehumwe chiyero, yakasimudzwa zvakaenzana, uye pH iri. inodzorwa pa3.5 kusvika 5.5 kuti uwane chromium-isina Dacromet yekuputira mvura.Chigadzirwa chacho chakanakira zvakatipoteredza uye chisina kusvibiswa.Iyo corrosion performance yakakwira kanomwe kusvika kagumi pane iyo yemagetsi, uye ine zvakare zvakanakira zvekupenya kwepamusoro, kuderedza kukweshera kwepamusoro, uye kukwirira kwemamiriro ekunze.Zhu Chengfei et al.Zinc poda, aluminium poda, wetting uye dispersing agent (doro kana polyalcohol), passivating agent (phytic acid), corrosion inhibitor (sodium molybdate), mvura, firimu rekugadzira agent (manganese acetate, manganese nitrate kana manganese chloride), rubatsiro rwekutora mafirimu (silane). coupling agent), kuumba rubatsiro (boric acid kana succinic acid) uye thickener (hydroxymethyl cellulose kana hydroxyethyl cellulose) inogadzirirwa maererano neimwe reshiyo kuti iwane hapana Kana ichienzaniswa neyakapfuura art, iyo chromium dacrox yekuputira mvura ine zvakanakira kusasvibisa, hapana kusvibiswa, kuderera kwesimba kushandiswa uye kwakanaka kupfeka kuramba.
Uchishandisa phosphoric acid sebhainda uye passivating agent, isingawanzo pasi inobatsira, aluminium poda, zinc poda, 85% phosphoric acid, aluminium hydroxide, hydrogen peroxide, calcium oxide, cetyl polyoxyethylene ether, hydroxypropyl cellulose ether, ammonium cerium nitrate uye ammonium nitrate yakasanganiswa. zvinoenderana neimwe reshiyo, yakamutswa zvakaenzana, uye pH inodzorwa kusvika 5.5, kuwana chromium-isina Dacromet yekuputira mvura ine yakanakisa corrosion kuramba.Tsvagiridzo iyi inoratidza kuti kuwedzera kweiyo isingawanzo pasi strontium munyu zvinonyatso kudzikisa kupfekedza.Iyo corrosion current ye layer ine yakanaka corrosion inhibition effect paDacromet coating.
