Nqe lus piav qhia:
1. Rau nws tus kheej me me, SiO2 nanopowder tuaj yeem ua tiav cov micro-cracks thiab pores tsim los ntawm lub zos shrinkage thaum lub sij hawm kho cov txheej txheem ntawm epoxy resin, txo txoj kev diffusion ntawm corrosive xov xwm, thiab txhim khu lub shielding thiab tiv thaiv kev ua tau zoo ntawm txheej;
2. Rau nws cov hardness siab, silica nanoparticle tsub kom lub hardness ntawm epoxy resin, yog li txhim kho cov neeg kho tshuab zog.
Tsis tas li ntawd, ntxiv qhov tsim nyog ntawm nano silicon oxide hais kuj tuaj yeem ua rau lub zog sib txuas ntawm cov epoxy txheej thiab txuas lub neej kev pab cuam ntawm txheej.
Nano silica yog ib qho khoom siv tsis zoo uas tsis yog xim hlau uas muaj cua sov thiab oxidation tsis kam.Nws lub xeev molecular yog peb-dimensional network qauv nrog [SiO4] tetrahedron raws li lub hauv paus structural unit.Ntawm lawv, cov pa oxygen thiab silicon atoms txuas ncaj qha los ntawm covalent daim ntawv cog lus, thiab cov qauv muaj zog, yog li nws muaj cov tshuaj lom neeg ruaj khov, zoo heev kub thiab huab cua tsis kam, thiab lwm yam.
Nano silicon dioxide tsuas yog ua lub luag haujlwm ntawm kev tiv thaiv corrosion hauv epoxy txheej.Ntawm qhov tod tes, nano SiO2 tuaj yeem ua tau zoo rau cov micro-nrhiav thiab qhov hws tsim nyob rau hauv cov txheej txheem kho ntawm epoxy resin, thiab txhim kho cov kev nkag mus;Ntawm qhov tod tes, cov pab pawg ua haujlwm ntawm nano silica thiab epoxy resin tuaj yeem tsim lub cev / tshuaj sib txuas cov ntsiab lus los ntawm adsorption lossis cov tshuaj tiv thaiv, thiab qhia Si-O-Si thiab Si-O-C bonds rau hauv cov saw molecular los tsim peb. -dimensional network qauv los txhim kho txheej adhesion.Tsis tas li ntawd, lub siab hardness ntawm nano SiO2 tuaj yeem txhim kho qhov hnav tsis kam ntawm txheej txheej, yog li ua kom lub neej ntev ntawm cov txheej txheej.
Cia txias:
SiO2 nanoparticles nano silica hmoov yuav tsum tau muab kaw zoo khaws cia hauv qhov chaw qhuav thiab txias.
