Porogaramu zitandukanye za selile hamwe nibiyikomokaho

Cellulose ni macromolecular polysaccharide igizwe na glucose, ibaho cyane mubimera bibisi n'ibinyabuzima byo mu nyanja. Nibintu byakwirakwijwe cyane kandi binini bya polymer karemano muri kamere. Ifite biocompatibilité nziza, ishobora kuvugururwa na Biodegradable nibindi byiza. Binyuze kuri fotosintezeza, ibimera birashobora guhuza toni miriyoni amagana ya selile buri mwaka.

Ibyifuzo bya Cellulose

Cellulose gakondo yagiye ikoreshwa cyane kubera imiterere yumubiri na chimique, mugihe ibintu bisanzwe bya polymer material selile bifite imikorere itandukanye nyuma yo gutunganya no kubihindura, bishobora guhuza ibikenerwa bitandukanye ninganda zitandukanye. Imikoreshereze yimikorere yibikoresho bya selile byahindutse inzira yiterambere ryiterambere hamwe nubushakashatsi bwibikoresho bya polymer.

Inkomoko ya selile ikorwa na esterification cyangwa etherification ya hydroxyl mumatsinda ya selile ya polymer hamwe na reagent ya chimique. Ukurikije imiterere yimiterere yibicuruzwa byabyitwayemo, ibikomoka kuri selile bishobora kugabanywamo ibyiciro bitatu: selile ya selile, ester selile, na selile ya ether.

1. Cellulose ether

Cellulose ether nijambo rusange ryuruhererekane rwibikomoka kuri selile byakozwe nigikorwa cya alkali selulose na etherifying agent mubihe bimwe. Cellulose ether ni ubwoko bwa selulose ikomoka hamwe nubwoko butandukanye, imirima yagutse ikoreshwa, ingano nini yumusaruro nagaciro gakomeye mubushakashatsi. Ikoreshwa ryarwo ririmo ibintu byinshi nkinganda, ubuhinzi, inganda z’imiti ya buri munsi, kurengera ibidukikije, ikirere ndetse n’ingabo z’igihugu.

Ethers ya selile ikoreshwa mubucuruzi ni: methyl selulose, carboxymethyl selulose, Ethyl selulose, hydroxyethyl selulose, cyanoethyl selulose, hydroxypropyl selulose na hydroxypropyl methylcellulose Cellulose nibindi.

2

Ester ya selile ikoreshwa cyane mubijyanye no kurinda igihugu, inganda z’imiti, ibinyabuzima, ubuvuzi, ubwubatsi ndetse n’ikirere.

Esters ya selulose ikoreshwa mubucuruzi ni: nitrat ya selulose, selile ya selile, selile ya acetate butyrate na selile xanthate.
3. Cellulose ether ester

Cellulose ether esters ni ester-ether ivanze.

Umwanya wo gusaba

1. Imiti yimiti

Cellulose ether nibikomoka kuri ester bikoreshwa cyane mubuvuzi kubyimbye, bidasanzwe, kurekurwa kuramba, kurekurwa kugenzurwa, gukora firime nibindi bikorwa.

2. Umwanya wo gutwikira

Cellulose esters igira uruhare runini mugutwikira porogaramu. Ester ya selulose ikoreshwa muri binders, ibisigarira byahinduwe cyangwa ibikoresho byabanjirije firime kugirango bitange ibifuniko nibintu byinshi byiza.

3. Umwanya wa tekinoroji ya Membrane

Cellulose n'ibiyikomokaho bifite ibyiza byo gusohora byinshi, imikorere ihamye, hamwe no kongera gukoreshwa. Binyuze murwego-rw-kwishyira hamwe, uburyo bwo guhinduranya icyiciro, tekinoroji ya electrospinning nubundi buryo, ibikoresho bya membrane nibikorwa byiza byo gutandukana birashobora gutegurwa. Mubyerekeranye na tekinoroji ya membrane ikoreshwa cyane.

4. Umwanya wo kubaka

Ether ya selile ifite imbaraga nyinshi zidasubirwaho kandi zikaba ingirakamaro kubwinyongera mubice byubwubatsi, nkibikoresho bya sima bishingiye kuri sima.

5. Ikirere, ibinyabiziga bishya byingufu nibikoresho bya elegitoroniki byo mu rwego rwo hejuru

Ibikoresho bishingiye kuri selile ikora ibikoresho bya optoelectronic birashobora gukoreshwa mubirere, ibinyabiziga bishya byingufu hamwe nibikoresho bya elegitoroniki byo mu rwego rwo hejuru.

6. Indi mirima

Ibibazo nigisubizo mugukoresha selile

Kugeza ubu, selile iracyafite ibitagenda neza. Bitewe n'ibiranga imiterere yacyo, selile ntishobora gushonga kandi biragoye gushonga mumashanyarazi asanzwe, bigabanya cyane iterambere no gukoresha ibikoresho bya selile. Nkumuti muke mumashanyarazi asanzwe, kubura thermoplastique, hydrophilicity nyinshi no kubura antibacterial.

Kubwibyo, gushushanya no kubaka ibikoresho bishya bikomoka kuri selile ni ishingiro ryo gukoresha neza selile, kandi guteza imbere ikoranabuhanga risesuye kandi ryiza rya selile ni inzira yingenzi kandi byemeza ko ikoreshwa rya selile.
