Umehluko phakathi kwe-Sodium CMC, i-Xanthan Gum ne-Guar Gum

I-sodium carboxymethyl cellulose (CMC), i-xanthan gum, ne-guar gum zonke zingama-hydrocolloid asetshenziswa kabanzi asetshenziswa ngezindlela ezahlukahlukene emkhakheni wokudla, owekhemisi, wezimonyo, nezimboni. Nakuba babelana ngokufana okuthile mayelana nezakhiwo zabo zokujiya, ukuzinzisa, kanye ne-gelling, kukhona futhi umehluko ophawulekayo ekwakhekeni kwamakhemikhali abo, imithombo, ukusebenza, kanye nokusetshenziswa kwazo. Ake sihlole umehluko phakathi kwalawa ma-hydrocolloid amathathu:

1. Isakhiwo Samakhemikhali:

• I-Sodium Carboxymethyl Cellulose (CMC): I-CMC iphuma ku-cellulose encibilika emanzini, okuyi-polysaccharide eyakhiwe amayunithi eglucose aphindaphindayo. Amaqembu e-Carboxymethyl (-CH2-COOH) ethulwa kumgogodla we-cellulose ngokusabela kwe-etherification, enikeza ukuncibilika kwamanzi kanye nezakhiwo zokusebenza ku-polymer.
• I-Xanthan Gum: I-Xanthan gum iyi-polysaccharide encane ekhiqizwa ngokuvutshelwa yi-bacterium i-Xanthomonas campestris. Iqukethe amayunithi aphindaphindayo e-glucose, mannose, ne-glucuronic acid, namaketanga aseceleni aqukethe izinsalela ze-mannose kanye ne-glucuronic acid. I-Xanthan gum yaziwa ngesisindo sayo samangqamuzana aphezulu kanye nezakhiwo eziyingqayizivele ze-rheological.
• I-Guar Gum: I-Guar gum itholakala ku-endosperm ye-guar bean (Cyamopsis tetragonoloba). Yakhiwe nge-galactomannan, i-polysaccharide ehlanganisa uchungechunge lwamayunithi e-mannose anamaketanga aseceleni e-galactose. I-Guar gum inesisindo samangqamuzana aphezulu futhi yenza izixazululo ze-viscous lapho inamanzi.

2. Umthombo:

• I-CMC isuselwa ku-cellulose, i-polymer yemvelo etholakala ezindongeni zamaseli ezitshalo.
• I-Xanthan gum ikhiqizwa nge-microbial fermentation of carbohydrates yi-Xanthomonas campestris.
• I-Guar gum itholakala ku-endosperm ye-guar bean.

3. Imisebenzi:

• I-Sodium Carboxymethyl Cellulose (CMC):
  • Isebenza njenge-thickener, stabilizer, binder, kanye nefilimu-yangaphambili emisebenzini ehlukahlukene.
  • Yakha amajeli abonisa ngale nashintshayo ngokushisa.
  • Ibonisa ukuziphatha kokugeleza kwe-pseudoplastic.
• I-Xanthan Gum:
  • Isebenza njenge-thickener, stabilizer, emulsifier, ne-ejenti yokumisa okwesikhashana.
  • Inikeza isilawuli se-viscosity esihle kakhulu kanye nokuziphatha kokunciphisa i-shear.
  • Yakha izixazululo ze-viscous namajeli azinzile.
• I-Guar Gum:
  • Isebenza njenge-thickener, stabilizer, binder, kanye ne-emulsifier.
  • Inikeza i-viscosity ephezulu kanye nokuziphatha kokugeleza kwe-pseudoplastic.
  • Yakha izixazululo ze-viscous namajeli azinzile.

4. Ukunyibilika:

• I-CMC incibilika kakhulu emanzini abandayo nashisayo, yakha izixazululo ezicacile nezibonakalayo.
• I-Xanthan gum iyancibilika emanzini abandayo nashisayo, inezindawo ezinhle kakhulu zokuhlakazeka kanye ne-hydration.
• I-Guar gum ibonisa ukuncibilika okulinganiselwe emanzini abandayo kodwa ihlakazeka kahle emanzini ashisayo ukuze yakhe izixazululo ze-viscous.

5. Ukuzinza:

• Izixazululo ze-CMC zizinzile phezu kwebanga elibanzi le-pH nezimo zokushisa.
• Izixazululo ze-Xanthan gum zizinzile phezu kwebanga elibanzi le-pH futhi amelana nokushisa, ukugunda, nama-electrolyte.
• Izixazululo ze-Guar gum zingabonisa ukuzinza okuncishisiwe ku-pH ephansi noma lapho kukhona ukugxila okuphezulu kosawoti noma i-calcium ions.

6. Izicelo:

• I-Sodium Carboxymethyl Cellulose (CMC): Isetshenziswa emikhiqizweni yokudla (isb., amasoso, okokugqoka, indawo yokubhaka), imithi (isb., amaphilisi, okokumiswa), izimonyo (isb., okhilimu, izinto zokuthambisa), izindwangu, nezisetshenziswa zasembonini (isb., amaphepha, okokuhlanza ).
• I-Xanthan Gum: Isetshenziswa kakhulu emikhiqizweni yokudla (isb., okokugqoka kwesaladi, amasoso, ubisi), imithi (isb, ukumiswa, ukunakekelwa komlomo), izimonyo (isb., okhilimu, umuthi wokuxubha), uketshezi lokumba uwoyela, nezinye izinto ezisetshenziswa ezimbonini.
• I-Guar Gum: Isetshenziswa emikhiqizweni yokudla (isb., izinto ezibhakwayo, ubisi, iziphuzo), imithi (isb, amaphilisi, izinto ezimisiwe), izimonyo (isb., okhilimu, okokugcoba), ukuphrinta kwendwangu, kanye noketshezi oluphuma ku-hydraulic fracturing embonini kawoyela.

Isiphetho:

Ngenkathi i-sodium carboxymethyl cellulose (CMC), i-xanthan gum, ne-guar gum yabelana ngokufana okuthile ekusebenzeni kwayo nasekusetshenzisweni kwayo njengama-hydrocolloid, futhi ikhombisa umehluko ohlukile ekwakhekeni kwamakhemikhali, imithombo, izakhiwo, kanye nokusetshenziswa kwayo. Ukuqonda lo mehluko kubalulekile ekukhetheni i-hydrocolloid efaneleke kakhulu yezinhlelo zokusebenza ezithile ezimbonini ezihlukahlukene. I-hydrocolloid ngayinye inikeza izinzuzo eziyingqayizivele nezici zokusebenza ezingalungiselelwa ukuhlangabezana nezidingo zokwakheka nezinqubo ezahlukene.
