E tele ituaiga o cellulose, ma o le a le eseesega o latou faʻaoga?

O le cellulose o se polymer fa'alenatura e tele ma tele e maua i totonu o puipui sela o la'au, e maua ai le lagolago ma le fa'amalo. O lo'o fa'avaeina i iunite kulukose e feso'ota'i fa'atasi e ala i fusi β-1,4-glycosidic. E ui o le cellulose lava ia o se mea tutusa, o le auala e faʻatulagaina ma faʻatautaia e maua ai ituaiga eseese ma mea eseese ma faʻaoga.

1.Microcrystalline Cellulose (MCC):

MCCe gaosia e ala i le togafitia o alava cellulose ma minerale acids, e maua ai ni mea laiti, tioata tioata.
Fa'aoga: E fa'aaogaina lautele e fai ma sui fa'apipi'i, fusifusia, ma fa'ama'i i vaila'au fa'afoma'i e pei o papa ma capsules. Ona o lona natura le lelei ma le sili ona fa'apipi'i, e fa'amautinoa e le MCC le tufatufaina tutusa o vaila'au ma fa'afaigofie le tu'uina atu o vaila'au.

2. Cellulose Acetate:

O le acetate cellulose e maua mai i le acetylating cellulose ma le acetic anhydride poʻo le acetic acid.
Fa'aoga: O lenei ituaiga o cellulose e masani ona fa'aaogaina i le gaosiga o alava mo 'ie, e aofia ai lavalava ma mea fa'aofuofu. O lo'o fa'afaigaluegaina fo'i i le gaosiga o fa'amama sikaleti, ata pu'e ata, ma ituaiga fa'amama eseese ona o lona natura semi-permeable.

3. Ethylcellulose:

O le Ethylcellulose e maua mai i le cellulose e ala i le fa'afo'iina i le ethyl chloride po'o le ethylene oxide.
Fa'aoga: O ona uiga lelei e fai ata tifaga ma le tete'e atu i so'o so'o e mafai ai ona fetaui lelei le ethylcellulose mo le fa'apipi'iina o fualaau fa'ama'i, ma maua ai le fa'asao fa'atonutonuina o vaila'au. E le gata i lea, o loʻo faʻaaogaina i le gaosiga o vaitusi, faʻapipiʻi, ma faʻapipiʻi faʻapitoa.

4.Hydroxypropyl Methylcellulose (HPMC):

HPMCe fa'apipi'iina e ala i le suitulaga o vaega hydroxyl o cellulose i vaega methyl ma hydroxypropyl.
Fa'aoga: E galue le HPMC o se mafiafia, fa'amautu, ma emulsifier i alamanuia eseese, e aofia ai mea'ai, mea teuteu, ma vaila'au. E masani ona maua i mea tau tausiga a le tagata lava ia e pei o lotions, kulimi, ma suauu, faʻapea foʻi ma meaʻai e pei o sosi, ofu, ma aisakulimi.

5. Sodium Carboxymethyl Cellulose (CMC):

O le CMC e gaosia e ala i le togafitia o le cellulose i le chloroacetic acid ma le alkali.
Fa'aoga: Ona o le maualuga o le solubility i le vai ma le mafiafia o mea,CMCo lo'o fa'aaogaina tele e fai ma fa'amautu ma suiga viscosity i mea'ai, vaila'au, ma fa'aoga tau alamanuia. E masani ona maua i mea tao tao, oloa susu, pa'u fulunifo, ma vailaau fa'amama.

6. Nitrocellulose:

O le Nitrocellulose e gaosia e ala i le faʻasalaina o le cellulose ma le faʻafefiloi o le nitric acid ma le sulfuric acid.
Fa'aoga: E fa'aaoga muamua i le gaosiga o mea pāpā, lacquers, ma palasitika celluloid. Nitrocellulose-based lacquers e lauiloa i le faʻamaeʻaina o fafie ma mea faʻapipiʻi taʻavale ona o lo latou vave faʻagogo ma mea maualuga iila.

7.Bacterial Cellulose:

O le cellulose faʻamaʻi e faʻapipiʻiina e nisi ituaiga o siama e ala i le faʻafefe.
Fa'aoga: O ona uiga fa'apitoa, e aofia ai le mama maualuga, malosi fa'amalosi, ma le biocompatibility, e fa'atauaina ai le cellulose siama i fa'aoga fa'afoma'i e pei o le fa'aofuina o manu'a, fa'ainisinia fa'ainisinia, ma faiga tu'uina atu vaila'au.

O ituaiga eseese o cellulose e ofoina atu le tele o talosaga i totonu o pisinisi eseese, e aofia ai vailaʻau, ie, meaʻai, mea teuteu, ma gaosiga. O ituaiga ta'itasi o lo'o iai mea fa'apitoa e fa'atatau mo fa'aoga fa'apitoa, e amata mai i le tu'uina atu o le lagolago fa'avae i vaila'au vaila'au i le fa'aleleia atili o mea'ai mea'ai po'o le avea o se suiga gafataulimaina i biotechnology. O le malamalama i nei eseesega e mafai ai ona fetaui lelei le filifiliga o ituaiga cellulose e fetaui ma manaoga faʻapitoa i faʻatinoga i talosaga eseese.
