Ni ubuhe butumwa bwasimbuwe na selire?

Gusimbuza Abami basohotse na seliki ni itsinda ryibice bitandukanye kandi byingenzi bikomoka kuri selile, rimwe muri biolulymers nyinshi kwisi. Aba bahanga mu guhindura imiti yitsinda rya hydroxyl (-Oh) ryumuyobozi wa selile, bikaviramo ibicuruzwa bitandukanye bifite ibintu bitandukanye na porogaramu. Porogaramu iva muri faruceuticals, ibiryo, ibicuruzwa byita kugiti cyawe, ibikoresho byubaka, imyenda, nibindi byinshi.

Imiterere ya selile:
Cellulose ni Umurongo Polysaccharide igizwe no gusubiramo ibice bya glucose bihujwe na β-1,4-Glycosic Bonds. Ibice byo gusubiramo bigizwe n'amatsinda atatu ya hydroxyl kuri glucose igice cya glucose, gituma selile yatunganijwe cyane kandi byoroshye kubihindura imiti itandukanye.

Synthesis yo gusimburwa na seliki yasimbuwe:
Synthesis yo gusimbuza abahanga ba fililoye ikubiyemo intangiriro yimikorere itandukanye kumatsinda ya hydroxyl yumugongo wa selile. Uburyo busanzwe bwo guhuza aba ba ba ENOLNOrimo birimo guhinduka no gushikama.

Ibitekerezo bifatika birimo gusimbuza amatsinda ya hydroxyl hamwe na alkyl cyangwa aryl amatsinda yo gushiraho impamyabumenyi. Ibi birashobora kugerwaho na alkyl halides, enkyl sulfated cyangwa alkyl eTHers mubihe bikwiye. Mubisanzwe byakoreshejwe abakozi ba alkylating muriyi reaction birimo methyl chloride, rothyl chloride, na Benzyl chloride.

Gukomera, kurundi ruhande, bikubiyemo gusimbuza itsinda rya hydroxyl hamwe nitsinda rya Acyl kugirango rigire ubumwe bwa ester. Ibi birashobora kugerwaho ukoresheje chloside ya aside, anhydride cyangwa accide imbere ya katali. Mubisanzwe byakoreshejwe mubintu bya Acylating muri ibi bitagenda harimo anhydride ya acetike, chloride ya acetyl, na acide yibinure.

Ubwoko bwa seliki yasimbuwe na selile:
Methyl Cellulose (MC):

Methycellse ikorwa no guhinduranya kwa selile hamwe na medori.
Bikoreshwa cyane nkumubyimba, stabilizer na emalisiire mu nganda zitandukanye harimo ibiryo, imiti nibicuruzwa byita kugiti cyawe.
MC ikora gel isobanutse iyo hydrad kandi igaragaza imyitwarire ya pseudoplastique, bigatuma habaho porogaramu isaba kugenzura visositity.
Hydroxyyerlcellylcellse (Hec):

HydroxyAythyl selile irahuza no gutandukanya selile na Ethylene oxide.
Bikunze gukoreshwa nka Thickener, umukozi ufatika hamwe na firime yo gushinga filime mubice, kwisiga, ubuvuzi nizindi nganda.
Hec itanga imyitwarire ya pseudoplastique kubisubizo kandi itanga ibintu byiza byamazi.
HydroxyProprilose (HPC):

HydroxyPropyl Tlix CellUlose ikorwa no gutandukanya selile hamwe na propaylene.
Ikoreshwa nkumunyefuni, stabilizer na binder muri farumasi, cyane cyane mubyoroheje kandi bigenzurwa-bigenzurwa na sisitemu yo gutanga ibiyobyabwenge.
HPC ifite imitungo ya thermogell, ikora geles yubushyuhe bwo hejuru.
Carboxymethylcellsellse (CMC):

Carboxymethylcellse igahagarara no gutandukanya selile na sodium monochlorotace itarangwamo alkaline.
Byakoreshejwe cyane nkumubyimba, stilizer na emalifie mubiryo, ibyifuzo bya farumasi na gahunda.
CMC itanga vicosity imyitwarire yoroheje yo gufungura ibisubizo no kwerekana ibice bya comloidal.
Etyl HydroxyAythyl Cellulose (Ehec):

Ethyl HydroxyAythyl selile ni ubumuga buteye isoni, bukorwa nuburyo bukurikiranye bwa selile hamwe na ethylene oxide na rotyl chloride.
Ikoreshwa nka Thickener, imvugo ya romesier na firime byahoze mubyiciro bitandukanye birimo amatara, ahisha hamwe nibicuruzwa byita kugiti cyawe.
Ehec ifite amazi menshi yo kwikebana no guhuza kuruta kuri bo hamwe na bagenzi babo.
Ibiranga Abami basimbuwe na selile:
Imitungo ya overi ya Celilose yasimbuwe bitewe nibintu nkurwego rwo gusimbuza, uburemere bwa molecular na miti yimiti. Ariko, mubisanzwe bagaragaza ibiranga bikurikira:

Hydrophility: Yasohoye Overteledated Overteleated Old ni hydrophilique kubera ko hariho amatsinda ya hydroprisile muburyo bwabo, bituma bakorana na molekile yamazi binyuze muri hydrodin.

Kwinginga no guhagarara: Benshi mu bahanga muri seliki basimbuwe na filime babyimbye kandi bakavamo imitungo, bikavamo gushiraho ibisubizo bya virusire cyangwa gels kuri hydtion. Viscosiya na gel imbaraga ziterwa nibintu nkibitekerezo bya polymer nuburemere bwa molekile.

Gushiraho filime: Bamwe bamenyesheje abakoresha ikarigo bashoboye gukora firime zisobanutse kandi zifunguye iyo zijugunywe igisubizo. Uyu mutungo ufite ibyiza mubisabwa nkibisohoka, kumenza, no kugenzurwa-kurekura byatanzwe na sisitemu yo gutanga ibiyobyabwenge.

Guhagarara: Gusimbuza abahanga ba selile muri rusange bimurika neza kumwanya munini wa PH nubushyuhe. Barwanya kwangirika kwa mikorobile na eydrolysis, bigatuma bakwirakwiriye kugirango bakore ibintu bitandukanye.

Imyitwarire yuburyo: Yashizeho abakora selile bakunze kwerekana imyitwarire ya pseudopplastique cyangwa amafaranga yoroheje, bivuze ko vico yabo iragabanuka munsi yimihangayiko. Uyu mutungo wifuzwa mubisabwa bisaba koroshya cyangwa gusaba.

Gusaba abakora selile basimbuwe.
Yasimbuye abahanga ba selile bakoreshwa cyane mu nganda nyinshi bitewe n'imiterere yabo yo mu mibare. Ibisabwa bimwe byingenzi birimo:

Inganda z'ibiryo: Yasohoye OUTHTERS nka CARBoxymethylcellSelcellse (CMC) ikoreshwa nk'abarimbyi, abigabye, kandi bamagana mu biribwa nk'isakoshi, imyambaro n'amata. Batezimbere imiterere, gushikama n'umunwa mugihe cyo kwagura ubuzima bwa filf.

Farumasiti: Yasimbuwe na selile ya Flimiulose yakoreshwaga cyane muri farumasi nka farumasi nka bunders, iganduzwa kandi igenzurwa nabakozi bashinzwe kurekura ibisate, capsules hamwe nibikorwa byingenzi. Batezimbere itangwa ryabiyobyabwenge, ibinyabuzima no kubara abarwayi.

Ibicuruzwa byita ku muntu: byasimbuye abakoresha kwa Celese bihuriweho mu bicuruzwa byita ku giti cye nka Shampoos, amavuta na cream bitewe no kubyimba kwabo, guhagarikwa no gukora siporo. Bizindukira ibicuruzwa bihamye, imiterere n'imiterere yibiranga.

Ibikoresho byubwubatsi: Ubundi buryo bwa Celilose bukoreshwa nkinyongera mubikoresho byubwubatsi nka croment hamwe nibicuruzwa bishingiye ku kunoza imikorere, kugumana amazi no kumeneka. Binoza imikorere no kuramba byibi bikoresho.

Imyenda: isimburwa na selile ya selile yo gucapa no kurangiza inzira yo gutanga ubugenzuzi bwa vino, gukomera no gukaraba. Bafasha murwego rwo kubitsa kuri dyes na pigment kuri subdeli.

Inganda za peteroli na gaze: Simbuza Abami Bakuru nka virusire hamwe nabakozi bashinzwe amazi mumazi yo gucumura neza numutekano wibikorwa byo gucukura peteroli na gaze.
