Ibyiciro byo gusiga irangi

Ukurikije amatsinda atandukanye akora, irangi rishobora kugabanywamo ubwoko bubiri: ubwoko bwa triazene bwa simmetrike nubwoko bwa vinylsulfone.

Ubwoko bwa triazene ya Symmetric: Muri ubu bwoko bwamabara asize, imiterere yimiti ya atome ya chlorine ikora cyane.Mugihe cyo gusiga irangi, atome ya chlorine isimburwa na fibre selile ya selile ya alkaline hanyuma igahinduka mumatsinda.Igisubizo hagati y irangi na fibre ya selile ni reaction ya bimolecular nucleophilique.

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 ibe itsinda rya vinyl sulfone.Itsinda rya vinyl sulfone rihuza fibre ya selile kugirango ikore nucleophilique reaction kugirango ikore ubumwe bwa covalent.

Irangi ryombi ryavuzwe haruguru nubwoko nyamukuru bwamabara asize hamwe nibisohoka byinshi kwisi.Mu rwego rwo kunoza igipimo cyo gutunganya amarangi adasubirwaho, amatsinda abiri yitabiriwe yinjiye muri molekile y'irangi mumyaka yashize, aribyo irangi ryibiri.

Irangi ryoroshye rishobora kugabanywamo ibice byinshi ukurikije amatsinda yabo atandukanye:

1. Irangi ryo mu bwoko bwa X ririmo itsinda rito rya dichloro-s-triazine, niryo bara rifite ubushyuhe buke, rikwiriye gusiga fibre selile kuri 40-50 ℃.

2. Irangi ryubwoko bwa K ririmo itsinda ryitwa monochlorotriazine, niryo rangi ryubushyuhe bwo hejuru, rikwiriye gucapwa no gusiga irangi kumyenda y'ipamba.

3. Ubwoko bwa KN bwirangi burimo amatsinda ya hydroxyethyl sulfone sulfate, aribara ryubushyuhe bwo hagati.Ubushyuhe bwo gusiga irangi 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.Irakwiriye gucapisha ubushyuhe buciriritse no gusiga irangi ipamba.

5. Ubwoko bwa KE bwirangi burimo amatsinda abiri yubusa kandi ni ay'ubushyuhe 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 ryitondewe 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 imikorere myiza iringaniye, amabara meza, umucyo mwiza, byoroshye gukoresha, chromatogramu yuzuye, nigiciro gito.

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

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