Epoxy iramenyerewe na bose.Ubu bwoko bwibinyabuzima nabwo bwitwa resin artificiel, resin glue, nibindi. Nubwoko bwingenzi cyane bwa plastike ya termosetting.Bitewe numubare munini wibikorwa bikora hamwe na polar, epoxy resin molekules irashobora guhuzwa kandi igakizwa nubwoko butandukanye bwimiti ikiza, kandi imitungo itandukanye irashobora gushirwaho wongeyeho inyongeramusaruro zitandukanye.

Nka resmosetting resin, epoxy resin ifite ibyiza byimiterere myiza yumubiri, izirinda amashanyarazi, gufatira neza, kurwanya alkali, kurwanya abrasion, gukora neza, gutuza no kugiciro gito.Nibimwe mubintu binini byibanze bikoreshwa mubikoresho bya polymer .. Nyuma yimyaka irenga 60 yiterambere, epoxy resin yakoreshejwe mubitambaro, imashini, ikirere, ubwubatsi nizindi nzego.

Kugeza ubu, epoxy resin ikoreshwa cyane mu nganda zitwikiriye, kandi igipfundikizo cyakozwe nacyo nka substrate cyitwa epoxy resin coating.Biravugwa ko gutwikira epoxy resin ari ibintu byinshi birinda ibintu bishobora gukoreshwa mu gupfuka ikintu icyo ari cyo cyose, kuva hasi, ibikoresho bikomeye by’amashanyarazi kugeza ku bicuruzwa bito bya elegitoroniki, kugira ngo birinde kwangirika cyangwa kwambara.Usibye kuba biramba cyane, epoxy resin coatings muri rusange irwanya kandi ibintu nka ingese na ruswa ya chimique, bityo ikaba izwi cyane mubikorwa byinshi bitandukanye no gukoresha.

Ibanga rya epoxy coating igihe kirekire

Kubera ko epoxy resin iri mubyiciro bya polymer yamazi, ikeneye ubufasha bwumuti ukiza, inyongeramusaruro hamwe na pigment kugirango yinjire muri epoxy irwanya ruswa.Muri byo, okiside ya nano ikunze kongerwaho nka pigment hamwe nuwuzuza kuri epoxy resin coatings, kandi abahagarariye bisanzwe ni silika (SiO2), dioxyde de titanium (TiO2), okiside ya aluminium (Al2O3), okiside ya zinc (ZnO), na oxyde idasanzwe.Nubunini bwihariye nuburyo bwihariye, iyi nano oxyde yerekana ibintu byinshi bidasanzwe byumubiri nubumashini, bishobora kuzamura cyane imiterere ya mashini na anti-ruswa.

Hariho uburyo bubiri bwingenzi bwa oxyde nano ibice byongera imbaraga zo kurinda epoxy coatings:

Ubwa mbere, hamwe nubunini bwayo buto, irashobora kuzuza neza micro-crack na pore zakozwe no kugabanuka kwaho mugihe cyo gukira kwa epoxy resin, kugabanya inzira yo gukwirakwiza ibitangazamakuru byangirika, kandi byongera imikorere yo gukingira no gukingira igifuniko;

Iya kabiri ni ugukoresha ubukana bwinshi bwibice bya oxyde kugirango wongere ubukana bwa epoxy resin, bityo uzamure imiterere yubukorikori.

Mubyongeyeho, wongeyeho urugero rukwiye rwa nano oxyde ya nano irashobora kandi kongera imbaraga zo guhuza imbaraga za epoxy coating kandi ikongerera igihe cyumurimo wa coating.

Uruhare rwanano silikaifu:

Muri iyi oxyde nanopowders, nano silicon dioxyde (SiO2) ni ubwoko bwo hejuru.Silica nano nikintu kidasanzwe kidafite ubutare hamwe nubushyuhe buhebuje hamwe na okiside.Imiterere ya molekuliyumu ni urwego rwibice bitatu byubatswe hamwe na tetrahedron [SiO4] nkigice cyibanze cyubaka.Muri byo, atome ya ogisijeni na silikoni ihuzwa mu buryo butaziguye n’imigozi ya covalent, kandi imiterere irakomeye, bityo ikaba ifite imiterere ihamye yimiti, ubushyuhe bwiza nubushyuhe bwikirere, nibindi.

Nano SiO2 ahanini ifite uruhare runini rwuzuza ruswa muri epoxy coating.Ku ruhande rumwe, dioxyde ya silicon irashobora kuzuza neza micro-crack na pore byakozwe mugukiza kwa epoxy resin, kandi bigateza imbere kwinjirira kwifata;kurundi ruhande ,,, Amatsinda yimikorere ya nano-SiO2 na epoxy resin arashobora gukora ingingo zifatika / imiti ihuza imipaka binyuze muri adsorption cyangwa reaction, hanyuma ikinjiza Si-O - Si na Si - O - C mumurongo wa molekile kugirango ubeho imiyoboro itatu-yimiterere kugirango itezimbere igifuniko.Byongeye kandi, ubukana bwinshi bwa nano-SiO2 burashobora kongera imbaraga zo kwihanganira kwambara, bityo bikongerera igihe cyo gukora.
