Selilulose ya Polyanionic (PAC) na Selilulose ya Sodium Carboxymethyl (CMC)

Selulosi ya Polyanionic (PAC) na selulosi ya sodium carboxymethyl (CMC) byombi ni ibikomoka kuri selulosi bikoreshwa cyane mu nganda zitandukanye mu rwego rwo kubyimbisha, gushimangira no gupima imikorere y’imitsi. Nubwo bisa bimwe na bimwe, bifite itandukaniro ritandukanye mu bijyanye n’imiterere ya chimique, imiterere, n’ikoreshwa ryayo. Dore igereranya hagati ya PAC na CMC:

1. Imiterere y'ibinyabutabire:
   • PAC: Polyanionic cellulose ni polymer ishongera mu mazi ikomoka kuri cellulose binyuze mu gushyira carboxymethyl n'andi matsinda ya anionic ku mugongo wa cellulose. Irimo amatsinda menshi ya carboxyli (-COO-) ku muyoboro wa cellulose, bigatuma iba anionic cyane.
   • CMC: Selulosi ya sodium carboxymethyl nayo ni polymer ishongesha amazi ikomoka kuri selulosi, ariko inyura mu buryo bwihariye bwa carboxymethylation, bigatuma amatsinda ya hydroxyl (-OH) asimburwa n'amatsinda ya carboxymethyl (-CH2COONa). Ubusanzwe CMC iba ifite amatsinda make ya carboxyl ugereranije na PAC.
2. Kamere ya Ionic:
   • PAC: Selulose ya polyanionic ni anionic cyane bitewe n'uko hari amatsinda menshi ya karubokisili ku ruhererekane rwa selulose. Igaragaza ubushobozi bukomeye bwo guhanahana iyoni kandi ikunze gukoreshwa nk'igikoresho cyo kugenzura kuyungurura no guhindura rheology mu mazi acukurwa ashingiye ku mazi.
   • CMC: Selulosi ya sodium carboxymethyl nayo ni anionic, ariko urwego rwayo rwa anionic ruterwa n'urwego rwo gusimbuza (DS) amatsinda ya carboxymethyl. CMC ikunze gukoreshwa nk'uburyo bwo gukurura, gushimangira, no guhindura viscosity mu bintu bitandukanye, harimo ibiribwa, imiti, n'ibikoresho byo kwita ku buzima bw'umuntu.
3. Ubucucike n'ubuhanga mu mikorere y'umubiri:
   • PAC: Selulose ya polyanionic igaragaza ubushyuhe bwinshi no kugabanya ubushyuhe mu gikoresho, bigatuma igira akamaro nk'ikintu gihindura ubushyuhe n'ubuhumekero mu bicukurwa no mu zindi nganda. PAC ishobora kwihanganira ubushyuhe bwinshi n'umunyu mwinshi ugaragara mu bikorwa byo mu birombe bya peteroli.
   • CMC: Selulosi ya sodium carboxymethyl nayo igaragaza ubushobozi bwo guhindura ubushyuhe n'ubuhumekero, ariko ubusanzwe ubushyuhe bwayo buba buri hasi ugereranije na PAC. CMC ikora ibisubizo bihamye kandi by’ubuhinduzi bw’ibishushanyo mbonera, bigatuma ikoreshwa mu buryo butandukanye, harimo ibiryo, amavuta yo kwisiga, n’imiti.
4. Porogaramu:
   • PAC: Selulose ya polyanionic ikoreshwa cyane cyane mu nganda za peteroli na gaze nk'igikoresho cyo kugenzura kuyungurura, guhindura rheology, no kugabanya igihombo cy'amazi mu mazi acukurwa. Ikoreshwa kandi mu zindi nganda nko mu bikoresho by'ubwubatsi no mu gusana ibidukikije.
   • CMC: Selulosi ya sodium carboxymethyl ikoreshwa mu nganda zitandukanye, harimo ibiribwa n'ibinyobwa (nk'inyongeramusaruro n'ingufu), imiti (nk'inyongeramusaruro n'igabanya ubushyuhe), ibikoresho byo kwita ku buzima bw'umuntu (nk'inyongeramusaruro y'amaraso), imyenda (nk'inyongeramusaruro y'ingano), n'inganda zikora impapuro (nk'inyongeramusaruro y'impapuro).

Mu gihe selulose ya polyanionic (PAC) na selulose ya sodium carboxymethyl (CMC) ari ibintu bikomoka kuri selulose bifite imiterere ya anionic kandi bisa mu nganda zimwe na zimwe, bifite itandukaniro rigaragara mu miterere ya chimique, imiterere, n'imikorere yihariye. PAC ikoreshwa cyane cyane mu nganda za peteroli na gaze, mu gihe CMC ikoreshwa cyane mu biribwa, imiti, kwita ku buzima bw'umuntu ku giti cye, imyenda, n'izindi nganda.
