1. Bakeng sa boholo ba eona bo nyenyane, SiO2 nanopowder e ka tlatsa ka katleho li-micro-cracks le li-pores tse entsoeng ke ho fokotseha ha sebaka sa heno nakong ea phekolo ea epoxy resin, ho fokotsa tsela ea ho hasana ha mecha ea phatlalatso e senyang, le ho ntlafatsa ts'ebetso ea tšireletso le e sireletsang ea ho roala;

2. Bakeng sa boima ba eona bo phahameng, silica nanoparticle e eketsa boima ba epoxy resin, kahoo e ntlafatsa thepa ea mechine.
Ntle le moo, ho eketsa palo e nepahetseng ea likaroloana tsa nano silicon oxide le hona ho ka eketsa matla a bonding ba sebopeho sa epoxy coating le ho lelefatsa bophelo ba ts'ebeletso ea ho roala.

Nano silica ke inorganic non-metallic material e nang le mocheso o babatsehang le ho hanyetsa oxidation.Boemo ba eona ba limolek'hule ke sebopeho sa marang-rang sa mahlakore a mararo se nang le [SiO4] tetrahedron e le setsi sa motheo sa sebopeho.Har'a tsona, liathomo tsa oksijene le silicon li kopantsoe ka ho toba ke litlamo tsa covalent, 'me sebopeho se matla, kahoo se na le lisebelisoa tse tsitsitseng tsa lik'hemik'hale, mocheso o babatsehang le ho hanyetsa boemo ba leholimo, joalo-joalo.

Nano silicon dioxide haholo-holo e bapala karolo ea anti-corrosion filler ho epoxy coating.Ka lehlakoreng le leng, nano SiO2 e ka tlatsa ka katleho li-micro-cracks le li-pores tse hlahisoang ts'ebetsong ea ho phekola epoxy resin, le ho ntlafatsa ho hanyetsa ho kenella;ka lehlakoreng le leng, lihlopha tse sebetsang tsa nano silica le epoxy resin li ka theha lintlha tsa 'mele / lik'hemik'hale tse kopanyang ka mokhoa oa adsorption kapa karabelo, le ho hlahisa li-bond tsa Si-O-Si le Si-O-C ka har'a ketane ea molek'hule ho etsa tse tharo. -dimensional netweke sebopeho ho ntlafatsa barbotage adhesion.Ho phaella moo, boima bo phahameng ba nano SiO2 bo ka ntlafatsa haholo ho hanyetsa ha seaparo, kahoo ho lelefatsa bophelo ba tšebeletso ea ho roala.

Boemo ba polokelo:

SiO2 nanoparticles nano silica phofo e lokela ho koaloa hantle e bolokiloe sebakeng se omileng le se phodileng.
