Tshaj tawm rau 2019-02-12Cov silicone thiab nano-hmoov kho nrog nano-dispersion yog dispersed mus rau hauv ib tug ntau ntawm resin cross-linked polymerized composite resins, thiab tom qab hloov kho, zinc hmoov thiab txhuas hmoov tuaj yeem tau txais kom muaj chromium-dawb, acid- resistant, thiab Magnesium alloy chromium-dawb dacromet tov nrog qhov zoo ntawm cov tshuaj tsuag ntsev, kev tiv thaiv ib puag ncig, nyias txheej zaj duab xis, huab cua zoo thiab cuam tshuam tsis kam.Zhang Shuyong et al.ntxiv zinc hmoov, txhuas hmoov, dej deionized, dispersant (decadiol polyoxyethylene ether los yog cetyl polyoxyethylene ether), phosphate (aluminium hydroxide thiab 85% phosphoric acid nyob rau hauv proportions), Thickener (dej-soluble methyl cellulose ether los yog hydroxypropyl methyl cellulose), tripolyphosphate, polymerization pib (35% hydrogen peroxide thiab / los yog potassium permanganate), pH regulator (zinc oxide, oxidation Calcium los yog calcium hydroxide) thiab filming pab (polyethylene glycol) yog tov raws li ib qho piv txwv, stirred tusyees, thiab pH yog. tswj ntawm 3.5 mus rau 5.5 kom tau txais cov dej tsis muaj chromium Dacromet txheej.Lub invention yog ib puag ncig tus phooj ywg thiab tsis muaj kuab paug.Kev ua haujlwm corrosion yog 7 mus rau 10 npaug siab dua li ntawm electrogalvanized, thiab nws kuj muaj qhov zoo ntawm cov permeability siab, kev sib txhuam siab, thiab huab cua tsis kam.Zhu Chengfei et al.Zinc hmoov, txhuas hmoov, wetting thiab dispersing tus neeg saib xyuas (cawv los yog polyalcohol), passivating tus neeg sawv cev (phytic acid), corrosion inhibitor (sodium molybdate), dej, zaj duab xis tsim tus neeg sawv cev (manganese acetate, manganese nitrate los yog Manganese chloride), filming pab (silane). coupling tus neeg sawv cev), tsim kev pab (boric acid los yog succinic acid) thiab thickener (hydroxymethyl cellulose los yog hydroxyethyl cellulose) yog npaj raws li ib tug piv txwv kom tsis txhob muab piv nrog cov ua ntej kos duab, cov chromium dacrox txheej kua muaj qhov zoo ntawm tsis muaj kuab paug, tsis muaj kuab paug, tsis muaj zog noj thiab zoo hnav tsis kam.
Siv cov phosphoric acid ua cov binder thiab passivating tus neeg saib xyuas, tsis tshua muaj lub ntiaj teb yog auxiliary, txhuas hmoov, zinc hmoov, 85% phosphoric acid, aluminium hydroxide, hydrogen peroxide, calcium oxide, cetyl polyoxyethylene ether, hydroxypropyl cellulose ether, ammonium cerium nitrate thiab ammonium nitrate yog tov. Raws li ib qho piv txwv, nplawm tusyees, thiab pH yog tswj rau 5.5, kom tau txais cov chromium-dawb dacromet txheej kua nrog zoo heev corrosion kuj.Kev tshawb fawb qhia tau hais tias qhov sib ntxiv ntawm lub ntiaj teb tsis tshua muaj strontium ntsev txo cov txheej txheem zoo.Lub corrosion tam sim no ntawm txheej muaj qhov zoo corrosion inhibition nyhuv ntawm Dacromet txheej.
