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

Polyanionic selulose (PAC) na sodium carboxymethyl selulose (CMC) byombi bikomoka kuri selile ikoreshwa cyane munganda zinyuranye kugirango zibyibushye, zihamye, hamwe na rheologiya. Mugihe basangiye bimwe, bafite itandukaniro ritandukanye mubijyanye nimiterere yimiti, imiterere, nibisabwa. Dore igereranya hagati ya PAC na CMC:

1. Imiterere ya shimi:
   • PAC: Cellulose ya polyanionic ni polymer ikemura amazi ikomoka kuri selile mugutangiza carboxymethyl hamwe nandi matsinda ya anionic kumugongo wa selile. Irimo amatsinda menshi ya carboxyl (-COO-) kumurongo wa selile, bigatuma anionic cyane.
   • CMC: Sodium carboxymethyl selulose nayo ni polymer yamazi yamazi akomoka kuri selile, ariko ikora inzira yihariye ya carboxymethylation, bikavamo gusimbuza amatsinda ya hydroxyl (-OH) hamwe nitsinda rya carboxymethyl (-CH2COONa). Ubusanzwe CMC irimo amatsinda mato ya carboxyl ugereranije na PAC.
2. Kamere ya Ionic:
   • PAC: Cellulose ya polyanionic ni anionic cyane kuberako hariho amatsinda menshi ya carboxyl kumurongo wa selile. Yerekana imbaraga zikomeye za ion-guhanahana amakuru kandi ikoreshwa kenshi nkigikoresho cyo kugenzura no kuyungurura imvugo mu mazi ashingiye kumazi.
   • CMC: Sodium carboxymethyl selulose nayo ni anionic, ariko urugero rwayo rwa anionicity biterwa nurwego rwo gusimbuza (DS) mumatsinda ya carboxymethyl. Ubusanzwe CMC ikoreshwa nkibyimbye, stabilisateur, hamwe noguhindura viscosity mubikorwa bitandukanye, harimo ibiryo, imiti, nibicuruzwa byita kumuntu.
3. Viscosity and Rheology:
   • PAC: Cellulose ya polyanionic yerekana ububobere buke hamwe nimyitwarire yogosha mugukemura, bigatuma ikora neza nkumuhinduzi wimbaraga na rheologiya mugucukura amazi nibindi bikorwa byinganda. PAC irashobora kwihanganira ubushyuhe bwinshi nubunini bwumunyu uhura nibikorwa bya peteroli.
   • CMC: Sodium carboxymethyl selulose nayo igaragaza ubwiza bwimiterere na rheologiya, ariko ububobere bwayo mubusanzwe buri hasi ugereranije na PAC. CMC ikora ibisubizo bihamye kandi bita pseudoplastique, bigatuma ikwirakwira muburyo butandukanye, harimo ibiryo, amavuta yo kwisiga, hamwe na farumasi.
4. Porogaramu:
   • PAC: Cellulose ya polyanionique ikoreshwa cyane cyane munganda za peteroli na gaze nkumukozi ushinzwe kugenzura akayunguruzo, guhindura imvugo, no kugabanya igihombo cyamazi mu gucukura amazi. Irakoreshwa kandi mubindi bikorwa byinganda nkibikoresho byubwubatsi no gutunganya ibidukikije.
   • CMC: Sodium carboxymethyl selulose ifite porogaramu zitandukanye mu nganda zinyuranye, zirimo ibiryo n'ibinyobwa (nk'ibyimbye na stabilisateur), imiti (nka binder na disintegrant), ibicuruzwa byita ku muntu (nk'umuhinduzi wa rheologiya), imyenda (nk'umukozi ufite ubunini) , no gukora impapuro (nk'inyongera y'impapuro).

mugihe byombi bya polyanionic selile (PAC) na sodium carboxymethyl selulose (CMC) nibikomoka kuri selile bifite imitungo ya anionic nibindi bisa mubikorwa bimwe na bimwe, bifite itandukaniro ritandukanye mubijyanye nimiterere yimiti, imiterere, nibisabwa byihariye. PAC ikoreshwa cyane cyane mu nganda za peteroli na gaze, mugihe CMC isanga ibintu byinshi mubiribwa, imiti, ubuvuzi bwihariye, imyenda, nizindi nganda.
