Kuyini i-sodium carboxymetyl cellulose?

I-Carboxymethylcelcelcellellulose (CMC) iyinhlangano yamakhemikhali eguquguqukayo futhi esetshenziswa kabanzi ethola izinhlelo zokusebenza ezimbonini ezahlukahlukene ngenxa yezakhiwo zayo ezihlukile. Le polymer isuselwa ku-cellulose, i-polymer yemvelo etholakala ezindongeni zeseli zezitshalo. I-Carboxymethylcellellulose ihlanganiswe ukuguqulwa kwamakhemikhali kwe-cellulose ngokusebenzisa ukwethulwa kwamaqembu e-carboxymethyl, athuthukisa amandla ayo okuzinikela kwamanzi.

Isakhiwo samangqamuvulelo kanye ne-synthesis

I-Carboxymethylcelcellellulose iqukethe amaketanga we-cellulose enamaqembu e-carboxymethyl (-ch2-cooh) anamathele kwamanye amaqembu ama-hydroxyl kumayunithi we-glucose. Ukuhlanganiswa kwe-CMC kufaka phakathi ukusabela kwe-cellulose nge-chlorosetic acid, okuholela ekufakweni kwama-athomu ama-hydrogen kumaqembu we-cellulose enamaqembu e-callulose enamaqembu e-callulose enamaqembu e-callulose. Izinga lokufakwa esikhundleni (DS), elibonisa inani eliphakathi lamaqembu e-carboxymethyl ngamunye uphiko lwe-glucose, othonya izakhiwo ze-CMC.

Izakhiwo Zomzimba Nezamakhemikhali

1. I-Solubinity: Enye yezinto eziphawuleka ze-CMC i-solubility yayo yamanzi, okwenza kube yi-ejenti yokuqina ewusizo ezixazululweni zamanzi. Izinga lokufaka esikhundleni lithinta i-solubity, elinama-DS aphezulu aholela ekukhulisweni kwamanzi.
2. I-Viscosity: I-Carboxymethylcelellellulose ibaluleke kakhulu emandleni ayo ukukhulisa ukubonakala koketshezi. Lokhu kwenza kube isithako esivamile emikhiqizweni ehlukahlukene, njengezinto zokudla, amakhamishini kanye nemikhiqizo yokunakekelwa komuntu siqu.
3. Izakhiwo ezenziwe ngefilimu: I-CMC ingakha amafilimu lapho yomile, efaka isandla kuzinhlelo zayo ezimbonini lapho kutholakala khona i-coatible coatible.
4. I-ION Exchange: I-CMC inezakhiwo ze-Ion Shintshana, zivume ukuthi zihlanganyele nama-ion ngesixazululo. Le mpahla ivame ukuxhashazwa ezimbonini ezifana nokushayela uwoyela kanye nokwelashwa kwamanzi amdaka.
5. Ukuqina: I-CMC iqinile ngaphansi kwezinhlobonhlobo zezimo ze-PH, izengeze ekuguquguqukeni kwayo kuzicelo ezihlukile.

Izinja

1. Imboni yokudla:

• Umenzeli wokuqina: I-CMC isetshenziswa njenge-ejenti yokuqina emikhiqizweni yokudla ehlukahlukene, kufaka phakathi amasoso, ukugqoka kanye nemikhiqizo yobisi.
• I-Stabilizer: Iqinisa ama-emulsion emikhiqizweni yokudla, ukuvikela ukwahlukana.
• I-Tecumeture Modifier: I-CMC ithuthukisa ukuthungwa kanye nomlomo wezinto ezithile zokudla.

2. Izemithi:

• I-Binder: I-CMC isetshenziswa njenge-binder kumathebulethi wezemithi, isiza ukubamba izithako ndawonye.
• Umenzeli wokumiswa: Kuqashwa emithini ewuketshezi ukuvikela ukuhlalisa izinhlayiya.

3. Imikhiqizo yokunakekelwa komuntu siqu:

• I-VisCosity Modifier: I-CMC ingezwa kwizimonyo, ama-shampoos kanye no-lotions ukulungisa ukubonakala kwawo futhi athuthukise ukuthungwa kwawo.
• I-Stabilizer: Iqinisa ama-emulsions ekwakhekeni kwezimonyo.

4. Imboni yamaphepha:

• Umenzeli we-Surface Sizing: I-CMC isetshenziswa embonini yamaphepha ukuthuthukisa izakhiwo ezingaphezulu zephepha, njengokushelela kanye nokuphrinta.

5 Imboni yendwangu:

• I-ejenti yezandla: I-CMC isetshenziswa kwimicu ukuthuthukisa izakhiwo zayo zokuluka futhi ithuthukise amandla endwangu ephumayo.

6. Ukushayela uwoyela:

• U-Fluid Loss Control Agent: I-CMC iqashwa ekudleni uketshezi ukulawula ukulahleka kwamanzi, ukunciphisa ingozi yokungazinzi kahle.

7. Ukwelashwa kwamanzi amdaka:

• I-Flocculanti: I-CMC isebenza njenge-flocculant ukuze ihlanganise izinhlayiya ezinhle, lula ukususwa kwayo ezinqubweni zokwelashwa kwamanzi amdaka.

Ukucatshangelwa Kwezemvelo

I-Carboxymethylcelcellellulose ithathwa njengephephile ukuze isetshenziswe kwizicelo ezahlukahlukene. Njenge-cellulose derivative, kuyinto ebonakalayo, futhi umthelela wayo wezemvelo uphansi. Kodwa-ke, kubalulekile ukucubungula i-Footprint yemvelo ephelele yokukhiqizwa kwayo nokusetshenziswa kwayo.

Ukugcina

I-Carboxymethylcellellulose iyi-polymer eguquguqukayo futhi ebalulekile enezicelo ezisabalele kuyo yonke imboni ehlukene. Inhlanganisela yayo eyingqayizivele yezakhiwo, kufaka phakathi i-solubity yamanzi, amandla okuqina, nokuqina, kwenza kube yingxenye ebaluleke kakhulu emikhiqizweni ehlukahlukene. Njengoba izimboni ziyaqhubeka nokufuna izixazululo ezizinzile nezisebenzayo, iqhaza le-carboxymethylcellellulose kungenzeka livele, futhi ucwaningo oluqhubekayo lungathola izinhlelo zokusebenza ezintsha zaleli polymer emangalisayo.
