Enwere ụdị cellulose dị iche iche, oleekwa ọdịiche dị na ojiji ha?

Cellulose bụ polymer dị ukwuu ma dị ukwuu nke dị na mgbidi cell nke osisi, na-enye nkwado nhazi na isi ike. Ihe mejupụtara ya bụ nkeji glucose jikọtara ọnụ site na njikọ β-1,4-glycosidic. Ọ bụ ezie na cellulose n'onwe ya bụ ihe na-emekọ ihe, otu esi ahazi ya na nhazi ya na-arụpụta ụdị dị iche iche nwere njirimara na ngwa dị iche iche.

1. Microcrystalline cellulose (MCC):

MCCa na-emepụta site n'ịgwọ eriri cellulose na ịnweta acids, na-ebute obere, kristal ahụ.
Na-eji: A na-eji ya eme ihe n'ọtụtụ ebe dị ka onye na-emepụta ihe na-emepụta ihe, ihe nkedo, na nke na-agbasasị na usoro ọgwụ dịka mbadamba na capsules. N'ihi ọdịdị inert ya yana ezigbo mkpakọ, MCC na-ahụ maka nkesa otu ọgwụ ma na-eme ka a tọhapụ ọgwụ.

2. Cellulose acetate:

A na-enweta acetate cellulose site na acetylating cellulose na acetic anhydride ma ọ bụ acetic acid.
Na-eji: Ụdị cellulose a na-ejikarị emepụta eriri maka textiles, gụnyere uwe na akwa. A na-arụkwa ya n'ọrụ n'ichepụta ihe nzacha sịga, ihe nkiri foto, na ụdị akpụkpọ anụ dị iche iche n'ihi ọdịdị ya nke nwere ike ime nke ọma.

3. Ethylcellulose:

Ethylcellulose sitere na cellulose site na iji ethyl chloride ma ọ bụ ethylene oxide meghachi omume ya.
Na-eji: Njirimara mmepụta ihe nkiri mara mma na iguzogide ihe ndị na-emepụta ihe na-eme ka ethylcellulose dị mma maka mkpuchi mbadamba ọgwụ, na-enye ntọhapụ nke ọgwụ. Na mgbakwunye, a na-arụ ya n'ọrụ na mmepụta inks, nrapado, na mkpuchi pụrụ iche.

4.Hydroxypropyl Methylcellulose (HPMC):

HPMCA na-emepụta ya site na iji otu methyl na hydroxypropyl dochie otu hydroxyl nke cellulose.
Na-eji: HPMC na-eje ozi dị ka thickener, stabilizer, na emulsifier n'ime ụlọ ọrụ dị iche iche, gụnyere nri, ihe ntecha, na ọgwụ. A na-ahụkarị ya na ngwaahịa nlekọta onwe onye dị ka lotions, ude, na manu, yana na ngwa nri dị ka sauces, mgbakwasa, na ice cream.

5.Sodium Carboxymethyl Cellulose (CMC):

A na-emepụta CMC site n'ịgwọ cellulose na chloroacetic acid na alkali.
Na-eji: N'ihi nnukwu mmiri solubility ya na ihe na-eme ka ọ dị arọ,CMCA na-eji ya nke ukwuu dị ka ihe nkwụsi ike na viscosity modifier na ngwaahịa nri, ọgwụ na ngwa ụlọ ọrụ mmepụta ihe. A na-ahụkarị ya n'ime ngwaahịa esiri esi, ngwaahịa mmiri ara ehi, ncha eze, na ncha.

6. Nitrocellulose:

Nitrocellulose na-emepụta site na nitrating cellulose na ngwakọta nke nitric acid na sulfuric acid.
Na-eji: A na-eji ya eme ihe n'ụzọ bụ isi n'ichepụta ihe mgbawa, lacquers, na plastik celluloid. Nitrocellulose dabeere na lacquers na-ewu ewu na ngwucha osisi na mkpuchi ụgbọ ala n'ihi na ha na-ehicha ngwa ngwa na nnukwu ihe na-egbuke egbuke.

7. Cellulose nke nje bacteria:

A na-emepụta cellulose nje bacteria site na ụfọdụ ụdị nje bacteria site na gbaa ụka.
Na-eji: Ngwongwo ya pụrụ iche, gụnyere ịdị ọcha dị elu, ike mgbakasị ahụ, na bioocompatibility, na-eme cellulose nke nje bacteria bara uru na ngwa ahụike dị ka mgbakwasa ọnya, ihe nhịahụ nke anụ ahụ, na usoro nnyefe ọgwụ.

Ụdị cellulose dị iche iche na-enye ngwa dịgasị iche iche n'ofe ụlọ ọrụ dị iche iche, gụnyere ọgwụ, textiles, nri, ihe ịchọ mma, na mmepụta ihe. Ụdị nke ọ bụla nwere ihe pụrụ iche na-eme ka ọ dabara maka ojiji a kapịrị ọnụ, sitere na inye nkwado nhazi na mbadamba ọgwụ ruo ịkwalite udidi nke ngwaahịa nri ma ọ bụ na-eje ozi dị ka ihe ọzọ na-adigide na nkà na ụzụ biotechnology. Ịghọta ọdịiche ndị a na-enyere aka nhọpụta ahaziri nke ụdị cellulose iji mezuo ihe achọrọ ịrụ ọrụ kpọmkwem na ngwa dị iche iche.
