1. Nokuda kwehukuru hwayo hudiki, SiO2 nanopowder inogona kunyatsozadza micro-cracks uye pores inoumbwa nemunharaunda shrinkage panguva yekurapa epoxy resin, kuderedza kupararira nzira yehutu hunopisa, uye kuwedzera kudzivirira nekudzivirira kushanda kwekuvhara;

2. Nokuda kwekuoma kwayo kwepamusoro, silica nanoparticle inowedzera kuoma kwe epoxy resin, nokudaro inosimudzira maitiro emagetsi.
Pamusoro pezvo, kuwedzera huwandu hwakakodzera hwenano silicon oxide zvidimbu zvinogona zvakare kuwedzera iyo interface yekubatanidza simba reiyo epoxy coating uye kuwedzera hupenyu hwebasa rejasi.

Nano silica is anorganic non-metallic material ine yakanakisa kupisa uye oxidation kuramba.Yayo mamorekuru mamiriro matatu-dimensional network ine [SiO4] tetrahedron seyakakosha zvimiro unit.Pakati pavo, maatomu eokisijeni nesilicon akabatanidzwa zvakananga ne-covalent bonds, uye chimiro chakasimba, saka chine makemikari akagadzikana ehupfumi, kupisa kwakanyanya uye kusagadzikana kwemamiriro ekunze, nezvimwewo.

Nano silicon dioxide inonyanya kuita basa reanti-corrosion filler mune epoxy coating.Kune rumwe rutivi, nano SiO2 inogona kunyatsozadza micro-cracks uye pores inogadzirwa mukurapa maitiro epoxy resin, uye kuvandudza kuramba kwekupinda;kune rumwe rutivi, mapoka anoshanda e nano silica uye epoxy resin anogona kuumba muviri / makemikari cross-linking points kuburikidza neadsorption kana reaction, uye kuunza Si-O-Si uye Si-O-C zvisungo mucheni ye molecular kuti iite zvitatu. -dimensional network dhizaini yekuvandudza coating adhesion.Uye zvakare, iyo yakakwira kuomarara kwe nano SiO2 inogona kuwedzera zvakanyanya kupfeka kuramba kwejasi, nekudaro kuwedzera hupenyu hwebasa rejasi.
