Cellulose Ether Nimwe Mubintu Byingenzi Polymer Kamere

Cellulose ether ni polymer karemano ikomoka kuri selile, nicyo kintu cyibanze cyimiterere yibimera.Nicyiciro cyingenzi cya polymers gifite inganda nyinshi zikoreshwa.Cellulose ether ni polymer-soluble polymer ifite imiterere myiza yo gukora firime, kandi ikoreshwa cyane nkibyimbye, binder, stabilisateur, na emulisiferi mubikorwa bitandukanye nkibiryo, imiti, amavuta yo kwisiga, nubwubatsi.

Cellulose ni polymer karemano cyane kwisi, kandi iboneka murukuta rw'utugingo ngengabuzima.Numunyururu muremure wa polysaccharide igizwe na glucose ibice bihujwe hamwe na β-1,4-glycosidic.Molekile ya selile ni urunigi rwumurongo rushobora gukora hydrogene ihuza iminyururu ituranye, bikavamo imiterere ikomeye kandi ihamye.

Cellulose ether ikorwa no guhindura imiti ya selile.Igikorwa cyo guhindura kirimo gusimbuza amwe mumatsinda ya hydroxyl (-OH) kuri molekile ya selile hamwe na ether matsinda (-O-).Uku gusimburwa kuvamo gukora polymer-e-soluber polymer igumana byinshi mubintu bya selile, nkuburemere bwa molekile nyinshi, ubukonje bwinshi, hamwe nubushobozi bwo gukora firime.

Ethers ikunze gukoreshwa cyane mu nganda ni methyl selulose (MC), hydroxypropyl selulose (HPC), hydroxyethyl selulose (HEC), na carboxymethyl selulose (CMC).

Methyl selulose (MC) ni selile ya selile ikorwa nigikorwa cya selile na methyl chloride.Ni polymer yamazi ashonga ikora igisubizo gisobanutse, kibonerana iyo gishonge mumazi.MC ifite imiterere myiza yo gukora firime kandi ikoreshwa cyane nkibyimbye kandi bihuza ibiryo, imiti, hamwe no kwisiga.Ikoreshwa kandi nka binder mubikoresho byubwubatsi nka plaster na sima.

Hydroxypropyl selulose (HPC) ni selile ya selile ikorwa nigikorwa cya selile hamwe na okiside ya propylene.Ni polymer yamazi ashonga ikora igisubizo gisobanutse, kibonerana iyo gishonge mumazi.HPC ifite imiterere myiza yo gukora firime kandi ikoreshwa nkibyimbye, bihuza, hamwe na stabilisateur mubiribwa, imiti, hamwe no kwisiga.Ikoreshwa kandi nka binder mubikoresho byubwubatsi nka beto na gypsumu.

Hydroxyethyl selulose (HEC) ni selile ya selile ikorwa nigikorwa cya selile hamwe na okiside ya Ethylene.Ni polymer yamazi ashonga ikora igisubizo gisobanutse, kibonerana iyo gishonge mumazi.HEC ifite uburyo bwiza bwo kubyimba no gutuza kandi ikoreshwa cyane nkibyimbye, binder, na emulisiferi mubiribwa, imiti, no kwisiga.Irakoreshwa kandi mubyimbye mumavuta yo gucukura peteroli no mugukora amarangi ya latex.

Carboxymethyl selulose (CMC) ni ether ya selile ikorwa nigikorwa cya selile hamwe na aside ya chloroacetic.Ni polymer yamazi ashonga ikora igisubizo gisobanutse, kibonerana iyo gishonge mumazi.CMC ifite umubyimba mwiza kandi utuje kandi ikoreshwa nkibyimbye, bihuza, na emulisiferi mubiribwa, imiti, hamwe no kwisiga.Irakoreshwa kandi nka binder mu mpapuro kandi nka stabilisateur mu myenda.

Imiterere ya selulose ether iterwa nurwego rwo gusimbuza (DS), niwo mubare ugereranije numubare wa ether kumurwi wa glucose kuri molekile ya selile.DS irashobora kugenzurwa mugihe cya synthesis ya selulose ether, kandi igira ingaruka kumashanyarazi, viscosity, hamwe na gel-form ya polymer.Ether ya selile ifite DS nkeya ntishobora gushonga mumazi kandi ifite ubukonje bwinshi

n'imiterere ya gel, mugihe abafite DS ndende barushaho gushonga mumazi kandi bafite ububobere buke hamwe nubutaka bwa gel.

Kimwe mu byiza byingenzi bya selile ether ni biocompatibilité yayo.Ni polymer karemano idafite uburozi, idafite allergiki, na biodegradable, bigatuma iba ibikoresho byiza byo gukoresha mubiribwa, imiti, no kwisiga.Irashobora kandi guhuzwa nibindi bikoresho byinshi, bigatuma iba ingenzi muburyo bwinshi.

Mu nganda zibiribwa, ether ya selile ikoreshwa nkibyimbye, stabilisateur, na emulisiferi mubicuruzwa bitandukanye nka sosi, imyambarire, nibicuruzwa bitetse.Irashobora gufasha kunoza imiterere no guhuza ibyo bicuruzwa, hamwe nubuzima bwabo bwubuzima hamwe nubuziranenge muri rusange.Ether ya selile irashobora kandi gukoreshwa mugusimbuza ibinure mubiribwa birimo amavuta make na calorie yagabanutse, kuko bishobora gufasha gukora amavuta yuzuye amavuta adakeneye amavuta yongeweho.

Mu nganda zimiti, selile ether ikoreshwa nka binder, disintegrant, kandi irekura-irekura muburyo bwa tablet.Irashobora gufasha kunoza uburyo bwo guhunika no gutembera kwa poro, kimwe no gusesa no bioavailable yibikoresho bya farumasi ikora.Ether ya selile nayo ikoreshwa nkibyimbye na stabilisateur muburyo bukomeye nka cream, amavuta yo kwisiga, na geles.

Mu nganda zo kwisiga, selulose ether ikoreshwa nkibyimbye, binder, na emulisiferi mubicuruzwa bitandukanye nka shampo, kondereti, no koza umubiri.Irashobora gufasha kunoza imiterere no guhuza ibyo bicuruzwa, kimwe no guhagarara kwabo hamwe nibikorwa rusange.Cellulose ether irashobora kandi gukoreshwa nka firime-yahoze mu kwisiga nka mascara na eyeliner, kuko ishobora gufasha gukora neza ndetse ikanashyirwa mubikorwa.

Mu nganda zubaka, ether ya selile ikoreshwa nka binder, kubyimbye, hamwe na stabilisateur mubikoresho bitandukanye nka plaster, sima, na minisiteri.Irashobora gufasha kunoza imikorere nimbaraga zibi bikoresho, hamwe no kubika amazi no gufata neza.Ether ya selile irashobora kandi gukoreshwa nkimpinduka ya rheologiya mumazi yo gucukura peteroli, kuko ishobora gufasha kugenzura ububobere nubwiza bwamazi.

Mugusoza, selulose ether ningirakamaro ya polymer isanzwe ifite inganda nyinshi.Yakozwe nuburyo bwo guhindura imiti ya selile kandi ifite amashusho meza yo gukora firime, kubyimba, no gutuza.Ether ya selile ikoreshwa cyane mubiribwa, imiti, amavuta yo kwisiga, nubwubatsi, kandi ni biocompatable, non-toxic, non-allergenic, and biodegradable.Hamwe nimiterere yihariye kandi itandukanye, selile ether izakomeza kuba ibikoresho byingenzi mumyaka myinshi iri imbere.
