Kunezinhlobo eziningana ze-cellulose, futhi yini umehluko ekusebenziseni kwazo?

I-Cellulose iyi-polymer ehlukahlukene futhi eningi yemvelo etholakala ezindongeni zeseli zezitshalo, ukuhlinzeka ukwesekwa okuhlelekile nokuqina. Kuhlanganiswa ama-glucose amayunithi axhumene ndawonye ngama-β-1,4-glycosidic bond. Ngenkathi i-cellulose uqobo iyinto enobunzima, indlela ehlelekile futhi ecubungule ngayo imiphumela ezinhlotsheni ezahlukahlukene ngezakhiwo ezahlukahlukene kanye nezicelo.

I-1.Microcrystalline Cellulose (MCC):

I-MCCKukhiqizwa ukwelapha imicu ye-cellulose ngama-mineral acid, okuholela ezinkineni ezincane, ze-crystalline.
Isebenzisa: Kusetshenziswa kabanzi njenge-ejenti enobuningi, i-binder, nokuqhekeka kokuqanjwa kwemithi njengamathebulethi kanye nama-caplule. Ngenxa yemvelo yayo yokuhlanza kanye nokuxineka okuhle, i-MCC iqinisekisa ukusatshalaliswa kwezidakamizwa okufanayo futhi kusiza ukukhishwa kwezidakamizwa.

I-2.CelLellose Acetate:

I-Celsulose Acetate itholakala nge-actery cellulose nge-acetic anhydride noma i-acetic acid.
Sebenzisa: Lolu hlobo lweselula luvame ukusetshenziselwa ukukhiqizwa kwemicu yezindwangu, kufaka phakathi izingubo kanye ne-upholstery. Iphinde yaqashwa ekwenziweni kwezihlungi zikagwayi, ifilimu yezithombe, kanye nezinhlobo ezahlukahlukene zolwelwesi ngenxa yemvelo yayo evunyelwe.

I-3.Ithylcelcellose:

I-Ethylcellose isuselwa ku-cellulose ngokuyiphendula nge-ethyl chloride noma i-ethylene oxide.
Isebenzisa: Izakhiwo zayo ezinhle kakhulu zefilimu ezenziwe ngefilimu kanye nokumelana nezixazululo ze-organic yenza i-ethylcellose ilungele amaphilisi wezemithi e-coang, enikeza ukukhishwa kwezidakamizwa ezilawulwayo. Ngokwengeziwe, kuqashwa ekukhiqizweni kwama-inks, anamathela, kanye nezimbobo ezikhethekile.

I-4.hydroxypropyll methylcellulose (HPMC):

I-HPMCihlelwe ngokufaka esikhundleni samaqembu we-hydroxyl ane-cellulose enamaqembu we-methyly kanye ne-hydroxypropyl.
Isebenzisa: I-HPMC isebenza njengesikhulu, i-Stabilizer, kanye ne-emulsifier ezimbonini ezahlukahlukene, kubandakanya nokudla, izimonyo kanye nemithi. Kuvame ukutholakala emikhiqizweni yokunakekelwa komuntu siqu njenge-lotion, okhilimu, kanye namafutha, kanye nezicelo zokudla ezinjengososo, ukugqoka kanye no-ayisikhilimu.

I-5.sodium carboxymethyl cellulose (CMC):

I-CMC ikhiqizwa ngokwelapha iselula nge-chlororose acid ne-alkali.
Isebenzisa: Ngenxa ye-solubility yayo ephezulu ye-solubility kanye nezakhiwo ezikhuthazayo,CmIsetshenziswa kakhulu njenge-stabilizer kanye ne-viscosity modifier emikhiqizweni yokudla, amakhamishini kanye nezicelo zezimboni. Kuvame ukutholakala ezimpahleni ezibhakiwe, imikhiqizo yobisi, amazinyo okugeza, kanye nama-detegents.

I-6.NitroClulose:

I-NitroCellulose ikhiqizwa yi-nitrating cellulose ngenhlanganisela ye-nitric acid ne-sulfuric acid.
Isebenzisa: Ngokuyinhloko oqashwe ekwenziweni kweziqhumane, ama-lacquers, kanye namapulasitiki e-celluloid. Ama-lacquers asuselwa ku-nitrocellulose athandwa ekuqedeni izinkuni nezigqoko zezimoto ngenxa yezakhiwo zazo ezisheshayo zomisha nezesicwebezelayo.

7.Bacterial Celluleose:

I-Bacterial Cellulose ihlelwe yizinhlobo ezithile zamagciwane ngokusebenzisa ukuvutshelwa.
Isebenzisa: Izakhiwo zayo ezihlukile, kufaka phakathi ubumsulwa obuphezulu, amandla ashubile, kanye ne-biocomtic, yenza ama-bacterial cellulose abaluleke ngezicelo ze-biomedical, ukugqoka kwezicubu, nezinhlelo zokulethwa kwezidakamizwa.

Izinhlobo ezahlukahlukene ze-cellulose zinikezela ngezinto eziningi zezicelo kuzo zonke izimboni ezahlukahlukene, kufaka phakathi amakhambi, izindwangu, ukudla, izimonyo kanye nokukhiqiza. Uhlobo ngalunye lunezakhiwo ezihlukile ezenza zilungele ukusetshenziswa okuthile, ezisukela ekuhlinzekeni ukwesekwa kwesakhiwo kumathebulethi ezekhemisi ukuthuthukisa ukuthungwa kwemikhiqizo yokudla noma ukukhonza njengenye indlela esimeme kwi-biotechnology. Ukuqonda lo mehluko kwenza ukukhethwa okuhambisana nezinhlobo ze-cellulose ukuhlangabezana nezidingo ezithile zokusebenza kuzicelo ezihlukile.
