Hydroxyyeryl selile (hec) rwose ni polymer. Kugirango dusobanukirwe byimazeyo ibi, dukeneye gucukumbura ibintu byibanze bya polymers, imiterere ya selile nibibi byayo, synthesis numutungo wa hydroxyyethyl selile, nibisabwa.
1. Ibitekerezo by'ibanze bya Polymers
Polymers ni Ibikoresho bya Macromolecular byakozwe numubare munini wo gusubiramo ibice (bita Monomers) bihujwe nibirobyi. Iyi monomers ikora imirongo miremire binyuze mubitekerezo byingenzi, gutanga polymers idasanzwe kumubiri no mumiti. Ukurikije amasoko yabo, polymers arashobora kugabana amacakubiri muri polymers na synthique polymeti. Polymers Kamere arimo selile, proteyine, na reberi karemano; Polymetike polymets ikubiyemo polyethylene, polystyrene, na polyvinyl chloride.
2. Cekwi nubuzima bwayo
Cellulose niworoheje kama cyane muri kamere muri kamere, cyane cyane uboneka mu rukuta rwa selile. Cellulose ni polysaccharide igizwe na β-d-glucose ifitanye isano na β (1 → 4) hamwe na glycosic inkwano, hamwe na karina rirenze. Kubera ibice byayo byasubiwemo bya glucose, selile ubwayo ni polymer isanzwe.
3. Synthesis n'imiterere ya HydroxyIthyll selile
Hydroxyyeryl selile ni ukomoka kuri selile, biboneka mu kumenyekanisha hydroxyyethyl (-CH₂ch₂oh) abasimbuye mu ruhererekane rwa TOLECULOSE. By'umwihariko, reacts ya selile hamwe na ethlorocetate cyangwa ethyl chlorocetate igisubizo kiri mubihe bya alkaline kugirango utange hydroxinethyl selile.
Ihuriro, hydroxyyeryl selilese iracyagumana imiterere miremire ya selile, ni ukuvuga urunigi nyamukuru rwagizwe igice kinini cya glucose. Nyamara, amatsinda amwe ya hydroxyl yasimbuwe nitsinda rya hydroxyeryethyl, kandi iri hinduka rituma ibiranga selile biranga hamwe nibiranga selile yumwimerere. Nubwo intangiriro yabasimbuye, HydroxyEthyl selile iracyari ikigo kinini cya molecular, kandi imiterere yacyo ikubiyemo ibice byasubiwemo, niko byujuje ibisobanuro bya polymer.
4. Ibyiza bya HydroxyIthyll selile
Nka polymer, hydroxyyeryl selile ifite ibintu bisanzwe bya polymer kuburyo bukurikira:
Uburemere bwo hejuru bwa molekilar: Uburemere bwa molekile bwa hydroxyithyl buri gihe hagati y'ibihumbi n'ibihumbi hamwe na miriyoni z'imicurane, byerekana ibiranga polymer bigaragara.
Ibisubizo: HydroxyEthyll selile irashobora gukora igisubizo cya Collous Collous ku mazi akonje n'amazi ashyushye. Viscosiya igisubizo cyayo ijyanye nuburemere bwa molekile nurwego rwo gusimbuza. Uyu mutungo ufite akamaro gakomeye muri porogaramu nyinshi.
THERMOSENTIVITIVITIVITIKI: IYI GEREZA Z'IMBONIZO HYDROXYithyl igisubizo gihinduka ubushyuhe, byerekana rero termosensivit, ni umutungo usanzwe wibisubizo bya polymer.
Ubushobozi bwo gukora firime hamwe na firime: Bitewe no kwishoramo n'imikoranire y'iminyururu ya polymer, hydroxyEyyl selile irashobora gukora imiterere ihamye mu gisubizo, ikayiha ubushobozi buhebuje n'ubushobozi buhebuje n'ubushobozi buhebuje n'ubushobozi buhebuje.
V. Gukoresha hydroxyyerthyl selile
Bitewe numutungo wihariye wa Polymer, HydroxyAythyl selile ikoreshwa cyane mumirima myinshi. Ibikurikira ni bimwe mubisanzwe:
Ibikoresho byubaka: Nkuko na cevement yongeyeho, hydroxyAbleyl, HydroxyAthyl Cellulose irashobora gutera imbere amazi n'amazi yo kugumana na sima yo kunyerera no kunoza imikorere yubwubatsi.
Gukora no gushushanya: Muri Coatings, HEC ikoreshwa nkuwabyimbye, stabilizer na firime yo gushiraho film kugirango utezimbere izoround kandi yoroshya.
Inzitizi: Umutungo wacyo mwiza ugira ikintu cyingenzi mubikorwa byinshi.
Inganda zimpapuro: Hec ikoreshwa mumpapuro no gutunganya kugirango atezimbere neza hamwe nimpapuro zimpapuro.
Kwisiga: Hec ikoreshwa cyane mumavuta, amenyo nibicuruzwa byita kuruhu.
Izi porogaramu zikoresha imitungo ya Polymer ya HydroxyAbethyl selile, nk'urubyiruko rwo hejuru, imitungo yo gukora film n'umutungo wa film n'umutekano, byerekana imikorere yayo n'akamaro nka polymer.
Hydroxyyeryl selile ni polymer yabonetse kubitekerezo bya selile. Imiterere yacyo ikubiyemo umubare munini wibice byinshi bya glucose, bikaba bikomeje kubiranga uburemere bukomeye bwa molekelar hamwe nimirongo nyuma yuburyo bwa hydroxyyerthyl. Hydroxyyethyl Kubwibyo, birashobora kuvuga neza ko HydroxyAythyl selile ni polymer ikomeye.
