Ibyiciro byo gusiga irangi

Ukurikije amatsinda atandukanye akora, amarangi ashobora kugabanywamo ubwoko bubiri: ubwoko bwa triazene bwa simmetrike nubwoko bwa vinylsulfone.

Ubwoko bwa triazene ya Symmetric: Muri ubu bwoko bwamabara adasanzwe, imiti ya chorine ikora cyane.Mugihe cyo gusiga irangi, atome ya chlorine isimburwa na fibre ya selile muburyo bwa alkaline hanyuma igahinduka mumatsinda.Igisubizo hagati y irangi na fibre ya selile ni bimolecular nucleophilique yo gusimbuza reaction.

Ubwoko bwa Vinyl sulfone: vinyl sulfone (D-SO2CH = CH2) cyangwa β-hydroxyethyl sulfone sulfate.Mugihe cyo gusiga irangi, hyd-hydroxyethyl sulfone sulfate igwa mumashanyarazi ya alkaline kugirango ikore vinyl sulfone.Itsinda rya vinyl sulfone rihuza fibre ya selile kugirango ikore nucleophilique reaction kugirango ikore ubumwe.

Amabara abiri ya reaction yavuzwe haruguru nubwoko nyamukuru bwamabara meza kandi asohoka cyane kwisi.Kugirango tunonosore igipimo cyogusiga amarangi adasubirwaho, amatsinda abiri yitabiriwe yinjiye muri molekile yamabara mumyaka yashize, aribyo irangi ryibiri.

Irangi ryoroshye rishobora kugabanywamo ibice byinshi ukurikije amatsinda yabo atandukanye:

1. Irangi ryubwoko bwa X ririmo dichloro-s-triazine reaction, ni irangi ryubushyuhe buke, rikwiriye gusiga fibre selile kuri 40-50 ℃.

2. Irangi ryubwoko bwa K ririmo amatsinda ya monochlorotriazine, niryo bara ryubushyuhe bwo hejuru, rikwiriye gucapwa no gusiga irangi kumyenda y'ipamba.

3. Ubwoko bwa KN bwirangi burimo amatsinda ya hydroxyethyl sulfone sulfate, ni amarangi yubushyuhe bwo hagati.Ubushyuhe bwo gusiga ni 40-60 ℃, bubereye gusiga irangi rya pamba, gusiga irangi ryinshi, no gucapa irangi risa nkibara ryinyuma;birakwiriye kandi gusiga irangi ryimyenda.

4. Irangi ryubwoko bwa M ririmo amatsinda abiri akora kandi ni ay'ubushyuhe bwo hagati.Ubushyuhe bwo gusiga irangi ni 60 ° C.Birakwiriye gucapisha ubushyuhe buciriritse no gusiga irangi no kumyenda.

5. Ubwoko bwa KE bwirangi burimo amatsinda abiri yubusa kandi ni mubushyuhe bwo hejuru bwo gusiga irangi, bikwiranye no gusiga ipamba nigitambara.

Ibiranga

1. Irangi rirashobora gukora hamwe na fibre kugirango ube umurunga wa covalent.Mubihe bisanzwe, uku guhuza ntikuzatandukana, ubwo rero irangi ryibara rimaze gusiga irangi kuri fibre, rizagira ibara ryiza ryihuta, cyane cyane kuvura neza.Byongeye kandi, fibre ntizacika nkibara rya vat nyuma yo gusiga irangi.

2. Ifite uburyo bwiza bwo kuringaniza, amabara meza, umucyo mwiza, byoroshye gukoresha, chromatogramu yuzuye, nigiciro gito.

3. Irashobora gukorerwa cyane mubushinwa, ishobora guhaza byimazeyo ibikenerwa byo gucapa no gusiga amarangi;ifite uburyo butandukanye bwo gukoresha, ntabwo ari ugusiga irangi rya selile gusa, ahubwo no gusiga irangi rya poroteyine hamwe nigitambara kivanze.

Turi abatanga amabara meza.Niba ushimishijwe nibicuruzwa byacu, nyamuneka twandikire.
