Qhov zoo ntawm SiO2 nanoparticle hauv cov kua roj vanish:

Disperse nano-silica rau hauv polyurethane kua roj vanish los npaj nano-silica composite txheej.Kev kuaj corrosion los ntawm txoj kev poob phaus, anodic polarization nkhaus thiab AC impedance kuaj tau pom tias tom qab ntxiv nano silicon dioxide hmoov, corrosion kuj ntawm polyurethane kua roj vanish yog txhim kho.Nyob rau tib lub sijhawm, qhov adhesion ntawm kev hloov kho polyurethane cov kua roj vanish yog nce, thiab kev tiv thaiv kev laus yog txhim kho.

Silica nanopowder hauv cov kua roj vanish, nws txhim kho cov xim ntawm ntau yam khoom xws li ntxuav tsis kam, ruaj khov, thiab corrosion kuj, thiab tuaj yeem muab cov haujlwm tshwj xeeb xws li tshuaj tua kab mob thiab kev tu tus kheej.Nws tuaj yeem txhim kho kev ruaj ntseg cia, dej tsis kam thiab lub hnub tiv thaiv ntawm txheej txheej, txhim kho thixotropy ntawm txheej, thiab tswj tau zoo ntawm cov txaws thiab sagging hauv kev tsim kho.Cov khoom siv kho tshuab, lub zog tensile, hardness, thiab yooj ntawm txheej zaj duab xis yog txhim kho, cov txheej txheem ntawm cov zaj duab xis yog ntau ilv thiab du, muaj ib tug zoo tiav, thiab cov hniav zoo nkauj kev ua tau zoo.Hard thiab hnav-resistant, muaj zog adhesion, thiab muaj cov yam ntxwv ntawm qhov kub thiab txias tsis kam, noo noo tsis kam, thiab tshuaj corrosion kuj.
