Iyini i-Sodium Carboxymethyl cellulose?

I-Carboxymethylcellulose (CMC) iyinhlanganisela yamakhemikhali eguquguqukayo futhi esetshenziswa kabanzi ethola ukusetshenziswa ezimbonini ezahlukahlukene ngenxa yezakhiwo zayo ezihlukile. Le polymer isuselwa ku-cellulose, i-polymer yemvelo etholakala ezindongeni zamaseli ezitshalo. I-Carboxymethylcellulose ihlanganiswa ukuguqulwa kwamakhemikhali e-cellulose ngokusungulwa kwamaqembu e-carboxymethyl, athuthukisa amandla ayo okuncibilika emanzini kanye nokujiya.

Isakhiwo se-Molecular and Synthesis

I-Carboxymethylcellulose iqukethe amaketanga e-cellulose anamaqembu e-carboxymethyl (-CH2-COOH) axhunywe kwamanye amaqembu e-hydroxyl kumayunithi e-glucose. Ukwenziwa kwe-CMC kuhilela ukusabela kwe-cellulose nge-chloroacetic acid, okuholela ekufakweni kwama-athomu e-hydrogen ochungechungeni lwe-cellulose ngamaqembu e-carboxymethyl. I-degree of substitution (DS), ekhombisa inani elimaphakathi lamaqembu e-carboxymethyl ngeyunithi ngayinye ye-glucose, lithonya izici ze-CMC.

Izakhiwo Zomzimba Nezamakhemikhali

1. Ukunyibilika: Esinye sezici eziphawulekayo ze-CMC ukuncibilika kwayo emanzini, okuyenza ibe i-ejenti yokuqina ewusizo ezixazululweni ezinamanzi. Izinga lokushintsha lithinta ukunyibilika, nge-DS ephezulu eholela ekwandeni kokuncibilika kwamanzi.
2. I-Viscosity: I-Carboxymethylcellulose ihlonishwa ngekhono layo lokwandisa i-viscosity yoketshezi. Lokhu kuyenza ibe isithako esijwayelekile emikhiqizweni eyahlukene, njengezinto zokudla, imithi, kanye nemikhiqizo yokunakekelwa komuntu siqu.
3. Izakhiwo Zokwakha Ifilimu: I-CMC ingakha amafilimu uma yomile, ibe negalelo ekusetshenzisweni kwayo ezimbonini lapho kudingeka khona ukunamathela okuthambile, okuguquguqukayo.
4. I-Ion Exchange: I-CMC inezindawo zokushintshanisa i-ion, eyivumela ukuthi ihlanganyele nama-ion kusixazululo. Lesi sakhiwo sivame ukuxhashazwa ezimbonini ezifana nokumba uwoyela nokuhlanza amanzi angcolile.
5. Ukuzinza: I-CMC izinzile ngaphansi kwezinhlobonhlobo zezimo ze-pH, ingeza ekusebenzisaneni kwayo ngezindlela eziningi ezinhlelweni ezihlukene.

Izinhlelo zokusebenza

1. Imboni Yokudla:

• I-Ejenti Yokuqina: I-CMC isetshenziswa njenge-ejenti yokuqina emikhiqizweni ehlukahlukene yokudla, okuhlanganisa amasoso, okokugqoka kanye nemikhiqizo yobisi.
• I-Stabilizer: Iqinisa ama-emulsions emikhiqizweni yokudla, ivimbela ukuhlukana.
• I-Texture Modifier: I-CMC ithuthukisa ukuthungwa nokuzwakala komlomo wezinto ezithile zokudla.

2. Ezemithi:

• Isibopho: I-CMC isetshenziswa njengesihlanganisi kumaphilisi emithi, esiza ukubamba izithako ndawonye.
• I-Suspension Agent: Isetshenziswa emithini engamanzi ukuvimbela ukuhlangana kwezinhlayiya.

3. Imikhiqizo Yokunakekela Umuntu:

• I-Viscosity Modifier: I-CMC yengezwa kuzimonyo, ama-shampoos, nama-lotions ukulungisa i-viscosity yako nokuthuthukisa ukuthungwa kwazo.
• I-Stabilizer: Iqinisa ama-emulsions ekwakhiweni kwezimonyo.

4. Imboni Yamaphepha:

• I-Surface Sizing Agent: I-CMC isetshenziswa embonini yamaphepha ukuthuthukisa izakhiwo zephepha, njengokushelela nokuphrinta.

5. Imboni Yezindwangu:

• I-ejenti yokulinganisa: I-CMC isetshenziswa kumafayibha ukuthuthukisa izakhiwo zawo zokuluka futhi ithuthukise amandla endwangu ewumphumela.

6. Ukumba Kawoyela:

• I-Ejenti Yokulawula Ukulahleka Kwe-Fluid: I-CMC isetshenziswa ekubhojweni okusamanzi ukuze kulawuleke ukulahlekelwa uketshezi, kuncishiswe ubungozi bokungazinzi kwe-wellbore.

7. Ukuhlanza Amanzi Angcolile:

• I-Flocculant: I-CMC isebenza njenge-flocculant ukuze ihlanganise izinhlayiya ezinhle, kube lula ukususwa kwazo ezinqubweni zokuhlanza amanzi angcolile.

Ukucatshangelwa Kwemvelo

I-Carboxymethylcellulose ngokuvamile ibhekwa njengephephile ukusetshenziswa ezinhlelweni ezihlukahlukene. Njengokuphuma kwe-cellulose, iyakwazi ukubola, futhi umthelela wayo kwezemvelo uphansi kakhulu. Kodwa-ke, kubalulekile ukucabangela yonke indawo yemvelo yokukhiqizwa nokusetshenziswa kwayo.

Isiphetho

I-Carboxymethylcellulose iyi-polymer eguquguqukayo futhi ebalulekile esetshenziswa kabanzi kuzo zonke izimboni ezahlukahlukene. Inhlanganisela yayo eyingqayizivele yezakhiwo, okuhlanganisa ukuncibilika kwamanzi, amandla okuqina, nokuzinza, kuyenza ibe ingxenye ebalulekile emikhiqizweni ehlukahlukene. Njengoba izimboni ziqhubeka nokufuna izixazululo ezisimeme nezisebenza kahle, indima ye-carboxymethylcellulose cishe izovela, futhi ucwaningo oluqhubekayo lungase lwembule izicelo ezintsha zale polymer ephawulekayo.
