Cellulose ikurura amazi neza?

Cellulose, ibinyabuzima byinshi cyane ku isi, byerekana ibintu bitangaje, kimwe muri byo ni ubushobozi bwo gufata amazi. Iyi miterere ya hygroscopique ya selile isanga ibikorwa byinshi mubikorwa bitandukanye, kuva imyenda kugeza imiti. Gusobanukirwa nuburyo bukoreshwa mumazi ya selile ni ngombwa mugutezimbere imikoreshereze yayo mubikorwa bitandukanye.

Iriburiro:

Cellulose, polysaccharide igizwe na glucose igizwe na β (1 → 4) imigozi ya glycosideque, nikintu cyambere cyubaka urukuta rwibimera. Ubwinshi bwayo muri kamere, kuvugururwa, hamwe na biodegradabilite bituma iba ibikoresho byifuzwa cyane mubikorwa byinshi byinganda. Imwe mu miterere ishimishije ya selile ni ubushobozi bwayo bwo gufata amazi neza. Ibi biranga bifite ingaruka zikomeye mubice bitandukanye nk'imyenda, gukora impapuro, ibiryo, imiti, na biomaterial. Gusobanukirwa nuburyo bushingiye kumyitwarire ya selile ya selile ningirakamaro mugukoresha imbaraga zayo zose muribi bikorwa.

Ibintu bigira uruhare mu gufata amazi na Cellulose:

Ibintu byinshi bigira uruhare mubushobozi bwo gufata amazi ya selile:

Crystallinity: Imiterere ya kristaline ya selile igira ingaruka zikomeye kumiterere yayo. Uturere twa Crystalline twerekana amazi make ugereranije n'uturere twa amorphous kubera kubuza amazi ya molekile.

Ubuso bwubuso: Ubuso bwa fibre ya selile igira uruhare runini mukunywa amazi. Kugabanura neza selile hamwe nubuso burebure buringaniye bikurura amazi menshi ugereranije na bulkier selile.

Hydrophilicity: Amatsinda ya Hydroxyl (-OH) aboneka muri molekile ya selile abaha hydrophilique, byorohereza kwinjiza amazi binyuze muri hydrogène.

Impamyabumenyi ya Polymerisation: Cellulose ifite urwego rwo hejuru rwa polymerisation ikunda kugira ubushobozi bwo kwinjiza amazi menshi kubera ko hari amatsinda menshi ya hydroxyl kuri misa imwe.

Ubushyuhe n'ubushuhe bugereranijwe: Ibidukikije nk'ubushyuhe n'ubushuhe bugereranije bigira ingaruka cyane ku myitwarire ya selile. Ubushyuhe bwo hejuru hamwe nubushuhe muri rusange byongera kwinjiza amazi kubera kwiyongera kwa molekile zamazi.

Uburyo bwo Kuranga:

Ubuhanga butandukanye bukoreshwa mukuranga imiterere yo kwinjiza amazi ya selile:

Isesengura rya Gravimetric: Uburyo bwa Gravimetric burimo gupima uburemere bwibiro bya selile ya selile iyo uhuye namazi mugihe. Ibi bitanga amakuru menshi kubijyanye no kwinjiza amazi hamwe nubushuhe buringaniye.

Fourier Guhindura Infrared Spectroscopy (FTIR): FTIR spectroscopy ikoreshwa mugusesengura impinduka mumatsinda yimikorere ya selile nyuma yo kwinjiza amazi. Guhinduranya mumwanya wimisozi nuburemere byerekana imikoranire hagati ya selile na molekile zamazi.

Gutandukanya X-ray (XRD): XRD ikoreshwa mugusuzuma impinduka ziterwa na selile ya selile nyuma yo kwinjiza amazi. Kugabanuka mubipimo byerekana kristu byerekana kubyimba fibre selile bitewe no gufata amazi.

Gusikana Electron Microscopy (SEM): SEM yemerera kubona amashusho yimpinduka zijyanye na morphologie muri fibre selile mbere na nyuma yo kwinjiza amazi. Itanga ubushishozi muburinganire bwimiterere nubushake bwibikoresho bya selile.

Gukoresha Cellulose nkibikoresho bya Hygroscopique:

Imiterere ya hygroscopique ya selile isanga ibintu bitandukanye mubikorwa bitandukanye:

Imyenda: Fibre ishingiye kuri selile nka pamba na rayon ikoreshwa cyane mugukora imyenda bitewe nubushobozi bwabo bwo gukuramo ubuhehere, butanga ihumure no guhumeka imyenda.

Gukora impapuro: Fibre ya selile ikora nkibikoresho byibanze mu gukora impapuro. Ibikoresho byabo byo gufata amazi bigira ingaruka kumpapuro, ubwiza, n'imbaraga.

Inganda zikora ibiribwa: Ibikomoka kuri selile nka methylcellulose na carboxymethylcellulose bikoreshwa nkibibyimba, stabilisateur, na emulisiferi mubicuruzwa byibiribwa. Ubushobozi bwabo bwo gufata amazi byongera imiterere nubuzima bwiza.

Imiti ya farumasi: Ibikoresho bikomoka kuri selile bikoreshwa muburyo bwa farumasi kubushobozi bwabo bwo kugenzura irekurwa ryibiyobyabwenge, kuzamura umutekano, no kongera bioavailability. Bafasha kandi mugusenyuka no gusesa ibinini na capsules.

Ibinyabuzima: Hydrogels ya selile na firime bigenda bigaragara nkibinyabuzima byizewe bikoresha imiti itandukanye, harimo gutanga ibiyobyabwenge, gukora ingirabuzimafatizo, no gukiza ibikomere. Ubushobozi bwabo bwo kwinjiza amazi butuma amazi meza no gukwirakwira neza.

Ubushobozi budasanzwe bwa Cellulose bwo gufata amazi bukomoka kumiterere yihariye yimiterere nubumara. Gusobanukirwa ibintu bigira uruhare mu kwinjiza amazi, uburyo bwo kuranga, no gukoresha selile nkibikoresho bya hygroscopique ningirakamaro mugutezimbere imikoreshereze yabyo mubikorwa bitandukanye. Ubushakashatsi bukomeje muri uru rwego bizarushaho kwagura ibikorwa no gutanga umusanzu mu iterambere ryibikoresho birambye hamwe nibikorwa byongerewe imbaraga.
