Hariho ubwoko bwinshi bwa organosilicon, muribwo buryo bwo guhuza silane hamwe nibintu bihuza bisa. Mubisanzwe biragoye kubantu bahuye gusa na organosilicon kubyumva. Ni irihe sano n'itandukaniro riri hagati yabyo?
umukozi wa silane
Nubwoko bwa organic silicon compound ikubiyemo ibintu bibiri bitandukanye bya chimique muri molekile zayo, bikoreshwa mugutezimbere imbaraga zifatika hagati ya polymers nibikoresho kama. Ibi birashobora kwerekeza ku kunoza kwizirika kwukuri no kuzamura ubushuhe, imvugo, nibindi bikorwa. Ibikoresho byo guhuza bishobora kandi kugira ingaruka zihindura akarere ka interineti kugirango zongere imipaka hagati yicyiciro kama n’ibinyabuzima.
Kubwibyo, ibikoresho byo guhuza silane bikoreshwa cyane munganda nkibifata, ibifuniko na wino, reberi, casting, fiberglass, insinga, imyenda, plastike, ibyuzuza, kuvura hejuru, nibindi.

Ibikoresho bisanzwe byo guhuza silane birimo:
Amazi arimo silane: bis - [3- (triethoxysilane) - propyl] - tetrasulfide, bis - [3- (triethoxysilane) - propyl] - disulfide
Aminosilane: gamma aminopropyltriethoxysilane, N - β - (aminoethyl) - gamma aminopropyltrimethoxysilane
Vinylsilane: Ethylenetriethoxysilane, Ethylenetrimethoxysilane
Epoxy silane: 3-glycidoxypropyltrimethoxysilane

Methacryloyloxysilane: gamma methacryloyloxypropyltrimethoxysilane, gamma methacryloyloxypropyltriisopropoxysilane

Uburyo bwibikorwa byumukozi uhuza silane:
Umukozi uhuza Silane
Silane irimo amatsinda abiri cyangwa menshi ya silicon ikora irashobora gukora nkumushinga woguhuza hagati ya molekile yumurongo, kwemerera molekile nyinshi zumurongo cyangwa macromolecules cyangwa amashami yashami yoroheje guhuza no guhuza mumiterere yibice bitatu, biteza imbere cyangwa bigahuza gushiraho imiyoboro ya covalent cyangwa ionic. hagati y'iminyururu ya polymer.
Umukozi uhuza ibice byingenzi bigize icyumba kimwe cy'ubushyuhe bwa silicone reberi, kandi ni ishingiro ryo kumenya uburyo bwo guhuza no guhuza amazina y'ibicuruzwa.
Ukurikije ibicuruzwa bitandukanye byerekana uko ibintu bimeze, ubushyuhe bwicyumba kimwe cyubushyuhe bwa silicone reberi irashobora gushyirwa mubwoko butandukanye nk'ubwoko bwa deacidification, ubwoko bwa ketoxime, ubwoko bwa alcool, ubwoko bwa deamination, ubwoko bwa deamidation, n'ubwoko bwa deacetylation. Muri byo, ubwoko butatu bwambere nibicuruzwa rusange byakozwe murwego runini.

Dufashe urugero rwa methyltriacetoxysilane rwambukiranya urugero, bitewe nigicuruzwa cya reaction ya acide acetike, byitwa ubushyuhe bwicyumba cya deacetylated icyumba cya silicone rubber.
Muri rusange, guhuza imiyoboro hamwe nibikoresho byo guhuza silane biratandukanye, ariko haribisanzwe, nka alpha series ya silane ihuza ibikoresho ihagarariwe na phenylmethyltriethoxysilane, yakoreshejwe cyane mubice bimwe byubushyuhe bwicyumba cyubushyuhe bwa silicone reberi.

Ihuriro rusange rya silane ririmo:

Silane idafite umwuma: alkyltriethoxyl, methyltrimethoxy
Ubwoko bwa Deacidification silane: triacetoxy, propyl triacetoxy silane
Ubwoko bwa Ketoxime silane: Vinyl tributone oxime silane, Methyl tributone oxime silane
