E nwere ọtụtụ ụdị cellulose, kedu ihe dị iche n'otú e si eji ha?

Cellulose bụ polima eke dị iche iche ma dịkwa ọtụtụ nke a na-ahụ n'ime mgbidi sel nke osisi, na-enye nkwado na nkwụsi ike. Ọ mejupụtara ya na nkeji glucose ejikọtara ọnụ site na njikọ β-1,4-glycosidic. Ọ bụ ezie na cellulose n'onwe ya bụ ihe yiri ibe ya, ụzọ esi hazie ya ma hazie ya na-eme ka ụdị dị iche iche nwee njirimara na ojiji dị iche iche.

1. Microcrystalline Cellulose (MCC):

MCCA na-emepụta ya site n'iji mineral acids gwọọ eriri cellulose, nke na-eme ka e nwee obere obere kristal.
Ojiji: A na-ejikarị ya eme ihe dị ka ihe na-eme ka ihe dị arọ, ihe na-ejikọ, na ihe na-agbaze ihe n'ime ọgwụ dịka mbadamba na kapsụl. N'ihi na ọ naghị arụ ọrụ nke ọma ma na-eme ka ọ dị mma, MCC na-ahụ na e kesara ọgwụ otu otu ma na-eme ka mwepụta ọgwụ dị mfe.

2. Cellulose Acetate:

A na-enweta cellulose acetate site na acetylating cellulose na acetylating anhydride ma ọ bụ acetic acid.
Ojiji: A na-ejikarị ụdị cellulose a emepụta eriri maka ákwà, gụnyere uwe na ihe mkpuchi. A na-ejikwa ya eme ihe na imepụta nzacha sịga, ihe nkiri foto, na ụdị akpụkpọ ahụ dị iche iche n'ihi na ọ na-abanye n'ime ihe.

3. Ethylcellulose:

A na-enweta Ethylcellulose site na cellulose site na imeghachi ya na ethyl chloride ma ọ bụ ethylene oxide.
Ojiji ya: Njirimara ya dị mma nke imepụta ihe nkiri na iguzogide ihe mgbaze organic na-eme ka ethylcellulose dị mma maka mkpuchi mbadamba ọgwụ, na-enye mwepụta ọgwụ n'okpuru njikwa. Na mgbakwunye, a na-eji ya eme ihe n'imepụta ink, ihe mmado, na mkpuchi pụrụ iche.

4.Hydroxypropyl Methylcellulose (HPMC):

HPMCA na-emepụta ya site na iji otu methyl na hydroxypropyl dochie otu hydroxyl nke cellulose.
Ojiji: HPMC na-arụ ọrụ dị ka ihe na-eme ka ihe sie ike, ihe na-eme ka ahụ sie ike, na ihe na-eme ka ihe sie ike n'ọtụtụ ụlọ ọrụ dị iche iche, gụnyere nri, ihe ịchọ mma, na ọgwụ. A na-ahụkarị ya na ngwaahịa nlekọta onwe onye dịka ude mmiri, ude mmiri, na mmanụ, yana n'ihe eji eme nri dị ka ihendori, ihe eji emechi ákwà, na ice cream.

5.Sodium Carboxymethyl Cellulose (CMC):

A na-emepụta CMC site na iji chloroacetic acid na alkali gwọọ cellulose.
Ojiji: N'ihi oke mmiri ya na-agbaze ma na-eme ka ọ sie ike,CMCA na-eji ya eme ihe nke ukwuu dị ka ihe na-eme ka ihe kwụsie ike ma na-agbanwe viscosity n'ihe oriri, ọgwụ, na ngwa ụlọ ọrụ mmepụta ihe. A na-ahụkarị ya n'ihe e ji eme achịcha, ihe e ji mmiri ara ehi mee, ihe e ji asa ezé, na ihe e ji asa ezé.

6.Nitrocellulose:

A na-emepụta nitrocellulose site na nitrating cellulose na ngwakọta nke nitric acid na sulfuric acid.
Ojiji: A na-ejikarị ya eme ihe n'ịmepụta ihe mgbawa, ihe mkpuchi, na plastik celluloid. Ihe mkpuchi ndị e ji nitrocellulose mee na-ewu ewu n'ịmecha osisi na mkpuchi ụgbọala n'ihi na ha na-akpọ nkụ ngwa ngwa ma na-egbuke egbuke.

7. Cellulose nje:

A na-emepụta cellulose nje site na ụdị nje bacteria ụfọdụ site na ịgbakọ.
Ojiji: Ihe pụrụ iche o nwere, gụnyere ịdị ọcha dị elu, ike nrụgide, na ndakọrịta ihe dị ndụ, na-eme ka cellulose nje baa uru na ojiji biomedical dịka ihe mkpuchi ọnya, ihe owuwu anụ ahụ, na sistemụ nnyefe ọgwụ.

Ụdị cellulose dị iche iche na-enye ọtụtụ ojiji n'ọtụtụ ụlọ ọrụ dị iche iche, gụnyere ọgwụ, ákwà, nri, ihe ịchọ mma, na mmepụta ihe. Ụdị ọ bụla nwere ihe pụrụ iche nke na-eme ka ọ dabara adaba maka ojiji ụfọdụ, site n'inye nkwado nhazi na mbadamba ọgwụ ruo ime ka udidi nke ngwaahịa nri dịkwuo mma ma ọ bụ ije ozi dị ka ihe ọzọ na-adịgide adịgide na teknụzụ bayoteknọlọji. Ịghọta ọdịiche ndị a na-eme ka nhọrọ nke ụdị cellulose ahaziri ahazi mezuo ihe achọrọ maka arụmọrụ dị iche iche na ngwa dị iche iche.
