Ni bangahe uzi kubyerekeye guhuza silane?

Amakuru

Ibikoresho byo guhuza Silane ni ubwoko bwimvange ya silicon irimo ibintu bibiri bitandukanye bya shimi muri molekile, bikoreshwa mugutezimbere imbaraga zifatika hagati ya polymers nibikoresho kama. Ibi birashobora kwerekeza ku kwiyongera kwifatizo ryukuri, kimwe no kunoza imiterere yubushuhe, imiterere ya rheologiya, nibindi bikorwa. Ibikoresho byo guhuza bishobora kandi kugira ingaruka zo guhindura igice cyimbere kugirango zongere imipaka hagati yicyiciro kama nimborera.
Kubwibyo,ibikoresho bya silanezikoreshwa cyane mu nganda nka adheshes, coatings na wino, rubber, casting, fiberglass, insinga, imyenda, plastike, kuzuza, no kuvura hejuru.

umukozi wo guhuza silane ..
Ibicuruzwa byayo bya kera birashobora guhagararirwa na formula rusange XSiR3, aho X nitsinda ridafite hydrolytike, harimo amatsinda ya alkenyl (cyane cyane Vi) hamwe nitsinda rya hydrocarubone hamwe nitsinda rikora nka CI na NH2 kurangiza, ni ukuvuga amatsinda akora ya karubone; R ni itsinda rya hydrolyzable, harimo OMe, OEt, nibindi
Amatsinda akora muri X akunda kwitwara hamwe nitsinda ryimikorere muri polymers kama, nka OH, NH2, COOH, nibindi, bityo bigahuza silane na polymers organic; Iyo itsinda rikora rifite hydrolyzed, Si-R ihinduka Si-OH hanyuma ibicuruzwa nka MeOH, EtOH, nibindi bikabyara. Si OH irashobora gukwirakwira hamwe no kubura umwuma hamwe na Si OH mu zindi molekile cyangwa Si OH hejuru yubutaka bwavuwe kugirango habeho imiyoboro ya Si O-Si, ndetse ikanakorana na okiside zimwe na zimwe kugirango zibe Si O zihamye, zemererasilaneguhuza nibikoresho bidasanzwe cyangwa ibyuma.
