Izakhiwo eziyisisekelo ze-carboxymethyl cellulose sodium CMC.

I-Sodium carboxymethylcellulose (CMC) iyi-polymer eguquguqukayo futhi eguquguqukayo enezinhlelo zokusebenza eziningi kuzo zonke izimboni ezahlukahlukene.Le nhlanganisela isuselwa ku-cellulose, i-polymer yemvelo etholakala ezindongeni zamaseli ezitshalo.I-CMC ikhiqizwa i-cellulose eshintsha amakhemikhali ngokwethula amaqembu e-carboxymethyl kumgogodla we-cellulose.I-sodium carboxymethylcellulose ewumphumela inezindawo ezihlukile ezenza ibe yigugu ezinhlelweni eziningi zokusebenza.

Isakhiwo samangqamuzana:

Isakhiwo samangqamuzana e-sodium carboxymethylcellulose siqukethe umgogodla we-cellulose onamaqembu e-carboxymethyl (-CH2-COO-Na) axhunywe kwamanye amaqembu e-hydroxyl kumayunithi e-glucose.Lokhu kuguqulwa kunikeza ukuncibilika nezinye izinto ezinenzuzo ku-cellulose polymer.

I-Solubility kanye nezixazululo zezakhiwo:

Enye yezinto eziyinhloko ze-CMC ukuncibilika kwayo emanzini.I-sodium carboxymethyl cellulose inyibilika kalula emanzini futhi yakha isisombululo se-viscous esisobala.Ukunyibilika kungalungiswa ngokushintsha i-degree of substitution (DS), okuyisilinganiso senani lamaqembu e-carboxymethyl ngeyunithi ngayinye ye-glucose ochungechungeni lwe-cellulose.

Izici ze-Rheological:

Ukuziphatha kwe-rheological kwezixazululo ze-CMC kuyaphawuleka.I-viscosity yezixazululo ze-CMC ikhula ngokugxila okukhulayo futhi incike kakhulu ezingeni lokushintshwa.Lokhu kwenza i-CMC ibe ukuqina okusebenzayo ezinhlelweni ezihlukahlukene, okuhlanganisa ukudla, imithi kanye nezinqubo zezimboni.

Izici ze-Ionic:

Ukuba khona kwe-sodium ion emaqenjini e-carboxymethyl kunikeza i-CMC uhlamvu lwayo lwe-ionic.Le mvelo ye-ionic ivumela i-CMC ukuthi ihlanganyele nezinye izinhlobo ezikhokhiswayo esixazululweni, iyenze ibe wusizo ezinhlelweni ezidinga ukubopha noma ukwakheka kwejeli.

ukuzwela kwe-pH:

Ukunyibilika kanye nezakhiwo ze-CMC kuthintwa i-pH.I-CMC inokunyibilika okuphezulu kakhulu futhi ibonisa ukusebenza kwayo okuhle kakhulu ngaphansi kwezimo ze-alkaline kancane.Kodwa-ke, ihlala izinzile phezu kwebanga elibanzi le-pH, ihlinzeka ngokuguquguquka kwezinhlelo zokusebenza ezahlukene.

Izakhiwo zokwakha ifilimu:

I-sodium carboxymethylcellulose inamandla okwenza ifilimu, okwenza ifaneleke izinhlelo zokusebenza ezidinga ukwakhiwa kwamafilimu amancane noma izimbotshana.Lesi sakhiwo singasetshenziselwa ukukhiqiza amafilimu adliwayo, izintambo zethebhulethi, njll.

Misa:

I-CMC izinzile ngaphansi kwezimo ezihlukahlukene zemvelo, okuhlanganisa izinga lokushisa kanye nezinguquko ze-pH.Lokhu kuzinza kunomthelela empilweni yayo yeshelufu ende kanye nokufaneleka kwezinhlelo eziningi ezahlukene.

I-Emulsion stabilizer:

I-CMC isebenza njenge-emulsifier esebenzayo futhi isiza ukuzinzisa ama-emulsion ekudleni nasezinhlelweni zokwakheka.Ithuthukisa ukuzinza kwe-emulsion yamafutha emanzini, isiza ukuthuthukisa ikhwalithi yonke kanye nempilo yeshalofu yomkhiqizo.

Ukugcinwa kwamanzi:

Ngenxa yekhono layo lokumunca amanzi, i-CMC isetshenziswa njenge-ejenti yokugcina amanzi ezimbonini ezahlukene.Le ndawo inenzuzo kakhulu ekusetshenzisweni okufana nezindwangu, lapho i-CMC isiza ukugcina umswakama wezindwangu phakathi nezinqubo ezihlukahlukene.

I-Biodegradability:

I-sodium carboxymethylcellulose ithathwa njenge-biodegradable ngoba itholakala ku-cellulose, i-polymer eyenzeka ngokwemvelo.Lesi sici sihambisana kakhulu nemvelo futhi sihambisana nesidingo esikhulayo sezinto ezisimeme kuzo zonke izimboni.

isicelo:

imboni yokudla:

I-CMC isetshenziswa kabanzi njenge-thickener, stabilizer kanye ne-texturizer ekudleni.

Ithuthukisa i-viscosity kanye nokuthungwa kwamasoso, okokugqoka kanye nemikhiqizo yobisi.

umuthi:

I-CMC isetshenziswa njengesihlanganisi ekwakhiweni kwethebulethi yezemithi.

Isetshenziselwa ukwakheka kwe-topical ukunikeza i-viscosity futhi ithuthukise ukuzinza kwama-gel nama-creams.

indwangu:

I-CMC isetshenziswa ekucubunguleni izindwangu njenge-ejenti yokulinganisa kanye ne-ejenti ejiya yokuphrinta ama-paste.

Ithuthukisa ukunamathela kodayi kwendwangu futhi ithuthukise ikhwalithi yokuphrinta.

Imboni kawoyela negesi:

I-CMC isetshenziselwa ukumba uketshezi ukulawula i-viscosity nezinto eziqinile ezimisiwe.

Isebenza njengesinciphisi sokulahlekelwa uketshezi futhi ithuthukisa ukuzinza kodaka lokumba.

Imboni yamaphepha:

I-CMC isetshenziswa njenge-ejenti yokugqoka iphepha ukuze kuthuthukiswe amandla nokuphrinta kwephepha.

Isebenza njengosizo lokugcina enqubweni yokwenza iphepha.

Imikhiqizo yokunakekelwa komuntu siqu:

I-CMC itholakala emikhiqizweni eyahlukene yokunakekelwa komuntu siqu efana nomuthi wokuxubha amazinyo kanye neshampoo njengesithako nesiqinisayo.

Inikela ekuthunjweni jikelele kanye nokuvumelana kwamafomula ezimonyo.

Izihlanzi kanye nezihlanzi:

I-CMC isetshenziswa njenge-thickener kanye ne-stabilizer ezintweni zokuhlanza uketshezi.

Ithuthukisa i-viscosity yesisombululo sokuhlanza, ithuthukise ukusebenza kwayo.

I-Ceramics ne-Architecture:

I-CMC isetshenziswa njenge-binder kanye ne-rheology modifier kuma-ceramics.

Isetshenziselwa izinto zokwakha ukuthuthukisa ukugcinwa kwamanzi kanye nezakhiwo zokwakha.

Ubuthi nokuphepha:

I-Carboxymethylcellulose ngokuvamile ibonwa njengephephile (i-GRAS) ngama-ejensi alawulayo ukuze isetshenziswe ekudleni nasezinhlelweni zemithi.Ayinabuthi futhi ibekezelelwa kahle, futhi ikhuthaza ukusetshenziswa kwayo kabanzi.

Ekuphetheni:

I-sodium carboxymethyl cellulose iyi-polymer enezici eziningi enezinhlobonhlobo zokusetshenziswa ezimbonini ezahlukahlukene.Izakhiwo zayo eziyingqayizivele, ezihlanganisa ukuncibilika kwamanzi, ukuziphatha kwe-rheological, izakhiwo ze-ionic namandla okwenza ifilimu, kuyenza ibe isithako esibalulekile ekudleni, emithini yemithi, ezindwangu kanye neminye imikhiqizo eminingi.Njengoba izimboni ziqhubeka nokufuna izinto ezisimeme nezisebenzayo, i-sodium carboxymethyl cellulose cishe izokhula ngokubaluleka, iqinise isikhundla sayo njengomdlali oyinhloko kumakhemikhali e-polymer kanye nezicelo zezimboni.
