Kubika amazi nihame rya HPMC

Kubika amazi numutungo wingenzi mubikorwa byinshi bikoresha hydrophilique nka selile ya selile.Hydroxypropylmethylcellulose (HPMC) ni imwe muri ethers ya selile ifite uburyo bwo kubika amazi menshi.HPMC ni polymer ya kimwe cya kabiri ikomoka kuri selile kandi ikoreshwa muburyo butandukanye mubikorwa byubwubatsi, imiti n’ibiribwa.

HPMC ikoreshwa cyane nkibyimbye, stabilisateur na emulisiferi mubicuruzwa bitandukanye byibiribwa nka ice cream, isosi hamwe n imyambarire kugirango byongere ubwiza, guhoraho hamwe nubuzima bwiza.HPMC ikoreshwa kandi mugukora imiti yimiti munganda zimiti nkibikoresho, bidahuza kandi bifata amashusho.Ikoreshwa kandi nkibikoresho bigumana amazi mubikoresho byubwubatsi, cyane cyane muri sima na minisiteri.

Kubika amazi numutungo wingenzi mubwubatsi kuko bifasha kurinda sima ivanze na minisiteri bishya kugirango bidakama.Kuma birashobora gutera kugabanuka no guturika, bikavamo intege nke kandi zidahinduka.HPMC ifasha kubungabunga amazi muri sima na minisiteri ikurura molekile zamazi hanyuma ikarekura buhoro buhoro mugihe, bigatuma ibikoresho byubwubatsi bikira neza kandi bigakomera.

Ihame ryo gufata amazi ya HPMC rishingiye kuri hydrophilicity.Bitewe no kuba hari hydroxyl groupe (-OH) muburyo bwa molekile, HPMC ifitanye isano namazi.Amatsinda ya hydroxyl akorana na molekile zamazi kugirango zibe imigozi ya hydrogène, bigatuma habaho igishishwa cyamazi gikikije iminyururu ya polymer.Igishishwa cya hydrated cyemerera iminyururu ya polymer kwaguka, ikongera ingano ya HPMC.

Kubyimba kwa HPMC ni inzira igenda iterwa nibintu bitandukanye nkurwego rwo gusimbuza (DS), ingano yingingo, ubushyuhe na pH.Urwego rwo gusimbuza bivuga umubare wamatsinda ya hydroxyl yasimbuwe kuri anhydroglucose murwego rwa selile.Iyo agaciro ka DS kari hejuru, hydrophilicity ninshi nuburyo bwiza bwo gufata amazi.Ingano ya HPMC nayo igira ingaruka ku gufata amazi, kuko uduce duto dufite ubuso bunini kuri buri gice, bigatuma amazi menshi yinjira.Ubushyuhe nagaciro ka pH bigira ingaruka kurwego rwo kubyimba no kubika amazi, nubushyuhe bwo hejuru hamwe nagaciro ka pH byongera kubyimba no kubika amazi ya HPMC.

Uburyo bwo gufata amazi ya HPMC bukubiyemo inzira ebyiri: kwinjiza no desorption.Mugihe cyo kwinjiza, HPMC ikurura molekile zamazi ziva mubidukikije, zigakora igishishwa cyamazi gikikije iminyururu ya polymer.Igishishwa cya hydration kibuza iminyururu ya polymer gusenyuka kandi igakomeza gutandukana, biganisha kubyimba HPMC.Molekules zamazi zinjiye zikora hydrogène hamwe nitsinda rya hydroxyl muri HPMC, bikongera imikorere yo gufata amazi.

Mugihe cya desorption, HPMC irekura buhoro buhoro molekile zamazi, bigatuma ibikoresho byubaka bikira neza.Kurekura buhoro buhoro molekile zamazi zituma sima na minisiteri bikomeza kuba byuzuye, bikavamo imiterere ihamye kandi iramba.Kurekura buhoro buhoro molekile zamazi nazo zitanga amazi ahoraho kuri sima na minisiteri, byongera inzira yo gukira no kongera imbaraga niterambere ryibicuruzwa byanyuma.

Muri make, gufata amazi ni umutungo wingenzi mu nganda nyinshi zikoresha hydrophilique nka selulose ethers.HPMC ni imwe muri ethers ya selile ifite imiterere yo gufata amazi menshi kandi ikoreshwa cyane mubikorwa byubwubatsi, imiti n’ibiribwa.Imiterere yo gufata amazi ya HPMC ishingiye kuri hydrophilique yayo, ituma ishobora gukuramo molekile zamazi ziva mubidukikije, bigakora igishishwa cyamazi gikikije iminyururu ya polymer.Igishishwa cyamazi gitera HPMC kubyimba, kandi kurekura buhoro buhoro molekile zamazi zituma ibikoresho byubaka bikomeza kuba byuzuye, bikavamo imiterere ihamye kandi iramba.
