Dị ka resin thermosetting, epoxy resin nwere uru nke ezigbo anụ ahụ, mkpuchi eletriki, ezigbo adhesion, nguzogide alkali, nguzogide abrasion, nrụpụta dị mma, nkwụsi ike na ọnụ ala.Ọ bụ otu n'ime resins kachasị ukwuu nke a na-eji eme ihe na ihe polymer .. Mgbe ihe karịrị afọ 60 nke mmepe, e jiriwo resin epoxy na mkpuchi, igwe, ikuku, ihe owuwu na ubi ndị ọzọ.

Ka ọ dị ugbu a, a na-ejikarị resin epoxy eme ihe na ụlọ ọrụ mkpuchi, na mkpuchi e ji ya mee ihe dị ka ihe a na-akpọ ihe mkpuchi epoxy resin.A na-akọ na mkpuchi epoxy resin bụ ihe nchebe siri ike nke enwere ike iji kpuchie ihe ọ bụla, site na ala, nnukwu ngwa eletriki na obere ngwaahịa eletrọnịkị, iji chebe ha pụọ ​​​​na mmebi ma ọ bụ iyi.Na mgbakwunye na ịdịte aka nke ukwuu, mkpuchi resin epoxy na-adịkarịkwa eguzogide ihe ndị dị ka nchara na corrosion kemịkalụ, yabụ na ha na-ewu ewu n'ọtụtụ ụlọ ọrụ na ojiji dị iche iche.

Ihe nzuzo nke mkpuchi mkpuchi epoxy

Ebe ọ bụ na resin epoxy so na ụdị nke polymer mmiri mmiri, ọ chọrọ enyemaka nke ndị na-agwọ ọrịa, ihe mgbakwunye na pigmenti iji banye n'ime mkpuchi epoxy na-eguzogide corrosion.N'ime ha, a na-agbakwunye nano oxides dị ka pigmenti na ndị na-ejuputa na mkpuchi epoxy resin, na ndị nnọchianya a na-ahụkarị bụ silica (SiO2), titanium dioxide (TiO2), aluminum oxide (Al2O3), zinc oxide (ZnO), na obere oxides ụwa.Site na nha na nhazi ha pụrụ iche, nano oxides ndị a na-egosipụta ọtụtụ ihe pụrụ iche nke anụ ahụ na kemịkalụ, nke nwere ike ime ka akụrụngwa na mgbochi corrosion dịkwuo elu nke mkpuchi ahụ.

Enwere isi ụzọ abụọ maka oxides nano particles iji kwalite arụmọrụ nchebe nke mkpuchi epoxy:

Nke mbụ, na obere nha nke ya, ọ nwere ike mejupụta micro-cracks na pores nke a na-emepụta site na shrinkage mpaghara n'oge usoro ọgwụgwọ nke resin epoxy, na-ebelata ụzọ mgbasa nke mgbasa ozi na-emebi emebi, ma welie nchebe na nchebe nke mkpuchi;

Nke abụọ bụ iji ike siri ike nke oxide ahụ na-eme ka ike nke resin epoxy dịkwuo elu, si otú ahụ na-eme ka ihe ndị na-emepụta ihe nke mkpuchi ahụ dịkwuo mma.

Tụkwasị na nke ahụ, ịgbakwunye ihe kwesịrị ekwesị nke nano oxide particles nwekwara ike ime ka ike njikọ interface nke mkpuchi epoxy gbasaa ma gbasaa ndụ ọrụ nke mkpuchi ahụ.

N'ime ndị a oxides nanopowders, nano silicon dioxide (SiO2) bụ ụdị ọnụnọ dị elu.Silica nano bụ ihe inorganic na-abụghị ọla nke nwere ezigbo nguzogide okpomọkụ na nguzogide oxidation.Ọnọdụ molekụla ya bụ usoro netwọkụ nwere akụkụ atọ nwere [SiO4] tetrahedron dị ka ngalaba nhazi ntọala.N'ime ha, ikuku oxygen na silicon atom na-ejikọta ya kpọmkwem site na njikọ covalent, na usoro ahụ siri ike, ya mere ọ nwere ihe ndị na-edozi ahụ, ezigbo okpomọkụ na ihu igwe, wdg.

Nano SiO2 na-arụkarị ọrụ nke ihe mgbochi corrosion na mkpuchi epoxy.N'otu aka ahụ, silicon dioxide nwere ike mejupụta micro-cracks na pores nke a na-emepụta na usoro ọgwụgwọ nke resin epoxy, ma melite ntinye ntinye nke mkpuchi;N'aka nke ọzọ, , The ọtọ ìgwè nke nano-SiO2 na epoxy resin nwere ike na-etolite anụ ahụ / chemical cross-njikọ ihe site adsorption ma ọ bụ mmeghachi omume, na-ewebata Si-O-Si na Si-O-C agbụ n'ime molekul yinye na-etolite. usoro netwọk akụkụ atọ iji meziwanye mkpuchi mkpuchi.Tụkwasị na nke ahụ, ịdị elu nke nano-SiO2 nwere ike ime ka nkwụsị nke mkpuchi ahụ dịkwuo elu, si otú ahụ na-agbatị ndụ ọrụ nke mkpuchi ahụ.
