I-Polyanionic Cellulose (PAC) ne-Sodium Carboxymethyl Cellulose (CMC)
I-Polyanionic cellulose (PAC) kanye ne-sodium carboxymethyl cellulose (CMC) kokubili okuphuma ku-cellulose asetshenziswa kakhulu ezimbonini ezihlukahlukene ukuze kuqiniswe, ukusimamisa, kanye nezakhiwo ze-rheological. Ngenkathi babelana ngokufana okuthile, baphinde babe nomehluko ohlukile ngokuya ngesakhiwo samakhemikhali, izakhiwo, kanye nokusetshenziswa. Nasi ukuqhathanisa phakathi kwe-PAC ne-CMC:
- Isakhiwo Sekhemikhali:
- I-PAC: I-Polyanionic cellulose iyi-polymer encibilika emanzini etholakala ku-cellulose ngokwethulwa kwe-carboxymethyl namanye amaqembu e-anionic kumgogodla we-cellulose. Iqukethe amaqembu amaningi e-carboxyl (-COO-) eduze kweketango le-cellulose, okuyenza ibe i-anionic kakhulu.
- I-CMC: I-Sodium carboxymethyl cellulose iphinde ibe i-polymer encibilika emanzini etholakala ku-cellulose, kodwa ibhekana nenqubo ethile ye-carboxymethylation, okuholela ekushintshweni kwamaqembu e-hydroxyl (-OH) namaqembu e-carboxymethyl (-CH2COONa). I-CMC ngokuvamile iqukethe amaqembu ambalwa e-carboxyl uma kuqhathaniswa ne-PAC.
- I-Ionic Nature:
- I-PAC: I-Polyanionic cellulose ine-anionic kakhulu ngenxa yokuba khona kwamaqembu amaningi e-carboxyl eduze kweketango le-cellulose. Ibonisa izakhiwo eziqinile ze-ion-exchange futhi ivame ukusetshenziswa njenge-ejenti yokulawula ukuhlunga kanye ne-rheology modifier kuketshezi lokumba olusekelwe emanzini.
- I-CMC: I-sodium carboxymethyl cellulose nayo iyi-anionic, kodwa izinga layo le-anionicity lincike ezingeni lokushintsha (DS) lamaqembu e-carboxymethyl. I-CMC ivamise ukusetshenziswa njenge-thickener, stabilizer, kanye nesilungisi se-viscosity ezinhlelweni ezihlukene, okuhlanganisa ukudla, imithi, nemikhiqizo yokunakekela komuntu siqu.
- I-Viscosity kanye ne-Rheology:
- I-PAC: I-Polyanionic cellulose ibonisa i-viscosity ephezulu kanye nokuziphatha kokunciphisa i-shear esixazululweni, okuyenza isebenze njengesiguquli esijiyayo nesiguquli se-rheology kuketshezi lokumba nezinye izinhlelo zokusebenza zezimboni. I-PAC ingakwazi ukumelana namazinga okushisa aphezulu kanye namazinga kasawoti atholwa emisebenzini yase-oilfield.
- I-CMC: I-Sodium carboxymethyl cellulose iphinde ibonise i-viscosity kanye nezakhiwo zokuguqulwa kwe-rheology, kodwa i-viscosity yayo ngokuvamile iphansi uma iqhathaniswa ne-PAC. I-CMC yenza izisombululo ezizinzile nezingamanga, iyenze ifanelekele uhla olubanzi lwezicelo, okuhlanganisa ukudla, izimonyo, kanye nemithi.
- Izicelo:
- I-PAC: I-Polyanionic cellulose isetshenziswa ngokuyinhloko embonini kawoyela negesi njenge-ejenti yokulawula ukuhlunga, i-rheology modifier, kanye nesinciphisi sokulahlekelwa uketshezi emanzini okumba. Ibuye isetshenziswe kwezinye izinhlelo zokusebenza zezimboni ezifana nezinto zokwakha kanye nokulungiswa kwemvelo.
- I-CMC: I-Sodium carboxymethyl cellulose inezinhlelo zokusebenza ezihlukahlukene ezimbonini ezihlukahlukene, okuhlanganisa ukudla neziphuzo (njenge-thickener and stabilizer), imithi yemithi (njenge-binder ne-disintegrant), imikhiqizo yokunakekelwa komuntu siqu (njenge-rheology modifier), izindwangu (njenge-ejenti yokulinganisa) , kanye nokukhiqizwa kwephepha (njengesengezo sephepha).
kuyilapho kokubili i-polyanionic cellulose (PAC) kanye ne-sodium carboxymethyl cellulose (CMC) kuyizinto eziphuma ku-cellulose ezinezakhiwo ze-anionic kanye nezicelo ezifanayo kwezinye izimboni, zinomehluko ohlukile mayelana nesakhiwo samakhemikhali, izakhiwo, kanye nezicelo ezithile. I-PAC isetshenziswa kakhulu embonini kawoyela negesi, kuyilapho i-CMC ithola ukusetshenziswa okubanzi ekudleni, kwezemithi, ekunakekelweni komuntu siqu, kwezindwangu, nakwezinye izimboni.
