Gahunda yo kubyara Acrylamide nihame

Uburyo bwo gukora

Uburyo 1: Uburyo bwa Hydrolysis
Uwitekaacrylamidebyabonetse muburyo bwa hydrolysis bifite gukwirakwiza bidasanzwe iminyururu ya acrylamide kumurongo wa macromolecular. Ijanisha rya maraacrylamideIminyururu kuri macromolecular iminyururu ni urwego rwa hydrolysis.
Ugereranije nuburyo bwa cololymerisation, amazi-soluble anti-dandruff factor (HD) yibicuruzwa byateguwe nuburyo rusange hydrolysis ntabwo ari hejuru, munsi ya 30%. Mubyukuri, ibicuruzwa bifite HD birenga 70% bigomba gutegurwa nuburyo bwa copolymerisation, bufite ibyo busabwa kubushyuhe bwa hydrolysis hamwe nibyabaye, kandi bikunda kwangirika kwa macromolekula mugihe cya hydrolysis.

Uburyo bwa 2: Polymerisation yumuti wamazi
Amazi yumuti polymerisation polymerisiyasi aho reaction ya monomer nuwatangije gushonga mumazi. Ubu buryo buroroshye, umwanda muke w’ibidukikije, umusaruro mwinshi wa polymer, byoroshye kubona polimeri ifite uburemere buke ugereranije, nuburyo bwa mbere bwakoreshejwe mu nganda zikora inganda za polyacrylamide, kandi bwabaye uburyo nyamukuru bwo gukora inganda za polyacrylamide. Polymerisation yumuti wamazi yarizwe cyane.

Uburyo 3: Inverted emulsion polymerisation
Sisitemu yo gukwirakwiza icyiciro cya colloidal ikeneye gutegurwa mbere yoguhindura icyiciro cya emulsion polymerisation na reversion-fonction polymerisation, ni ukuvuga, amazi / amavuta (W / 0) sisitemu yo gukwirakwiza heterogeneous ikorwa mugice cyamavuta yumuti wamazi wa monomer ukurura gutatanya. cyangwa emulifier, hanyuma uwatangije yongewe kubusa polymerisation yubusa.
Mubisanzwe, abatangiza amavuta ya elegitoronike akoreshwa muguhindura icyiciro cya emulsion polymerisation, cyane cyane anionic yubusa radical yatangije na non-ionic free radical radical, mugihe ihindagurika ryicyiciro cyo guhagarika polymerisation ikoresha intangiriro zamazi, nka persulfate. Hano hari ibitekerezo bibiri kuri nucleation ya AM / AA ihinduranya emulion polymerisation: micellar nucleation na monomer droplet nucleation. Kinetics iratandukanye cyane nubusanzwe positif positif nziza.

Uburyo bwa 4: Guhindura polymerisiyasi
Guhindura icyiciro cyahagaritswe polymerisation nuburyo bwiza bwo kubyaza umusaruro inganda za polymer zishonga amazi yakozwe mumyaka 10 ishize. Di-monie yize AM ihinduranya-icyiciro cyo guhagarika polymerisation ikoresheje imiyoboro, NMR na microscopi ya electron mu 1982.

Uburyo 5: Ubundi buryo bwa polymerisation
Usibye uburyo bwavuzwe haruguru, homopolymer na copolymer ya acrylamide nibiyikomokaho birashobora guhindurwa na reaction ya Mannich no guhimba copolymerisation. Kwinjiza amine muri polyacrylamide mugihe cya Mannich reaction nuburyo bwingenzi bwo kubona cationic polyelectrografting ya polyacrylamide. Amine akunze gukoreshwa ni dimethylamine, diethylamine, diethanolamine nibindi.

AM / AA ikunze gushyirwaho ibinyamisogwe kugirango itegure ibisigazwa byinjira cyane, cyangwa hamwe nabandi ba monomolecular monomers kugirango bashire AM / AA mubice bimwe. Ibiro byinshi bya molekuline cationic polyacrylamide (CPAM) bikoreshwa cyane mugukora amavuta, ariko HPAM ifite kwihanganira umunyu muke.
