I-Polyanionic Cellulose (PAC) kanye ne-Sodium Carboxymethyl Cellulose (CMC)

I-Polyanionic cellulose (PAC) kanye ne-sodium carboxymethyl cellulose (CMC) zombili ziyi-cellulose derivatives ezisetshenziswa kabanzi ezimbonini ezahlukahlukene ngenxa yezakhiwo zazo zokujiya, ukuzinza, kanye ne-rheological. Ngenkathi zabelana ngokufana okuthile, zinemehluko ohlukile ngokwesakhiwo samakhemikhali, izakhiwo, kanye nezinhlelo zokusebenza. Nasi ukuqhathanisa phakathi kwe-PAC ne-CMC:

1. Isakhiwo Samakhemikhali:
   • I-PAC: I-polyanionic cellulose iyi-polymer encibilika emanzini etholakala ku-cellulose ngokufakwa kwe-carboxymethyl namanye amaqembu e-anionic kumgogodla we-cellulose. Iqukethe amaqembu amaningi e-carboxyl (-COO-) eduze kwe-cellulose chain, okwenza ibe yi-anionic kakhulu.
   • I-CMC: I-sodium carboxymethyl cellulose nayo iyi-polymer encibilika emanzini etholakala ku-cellulose, kodwa idlula enkambisweni ethile ye-carboxymethylation, okuholela ekufakweni kwamaqembu e-hydroxyl (-OH) ngamaqembu e-carboxymethyl (-CH2COONa). I-CMC ngokuvamile iqukethe amaqembu e-carboxyl ambalwa uma kuqhathaniswa ne-PAC.
2. Imvelo ye-Ionic:
   • I-PAC: I-polyanionic cellulose i-anionic kakhulu ngenxa yokuba khona kwamaqembu amaningi e-carboxyl eceleni kwe-cellulose chain. Ibonisa izakhiwo eziqinile zokushintshana kwama-ion futhi ivame ukusetshenziswa njenge-ejenti yokulawula ukuhlunga kanye nokuguqula i-rheology oketshezini lokubhoboza olusekelwe emanzini.
   • I-CMC: I-sodium carboxymethyl cellulose nayo iyi-anionic, kodwa izinga layo le-anionicity lincike ezingeni lokushintshaniswa (DS) kwamaqembu e-carboxymethyl. I-CMC ivame ukusetshenziswa njengesithambisi-ndlela sokuqina, ukuzinza, kanye nokuguqula i-viscosity ezinhlotsheni ezahlukahlukene, okuhlanganisa ukudla, imithi, kanye nemikhiqizo yokunakekela umuntu siqu.
3. Ukuqina kanye ne-Rheology:
   • I-PAC: I-polyanionic cellulose ibonisa ukujiya okuphezulu kanye nokuziphatha kokunciphisa ukugunda esixazululweni, okwenza isebenze njengesithambisi sokujiya kanye nesiguquli se-rheology eziphuzweni zokubhoboza kanye nezinye izinhlelo zokusebenza zezimboni. I-PAC ingamelana namazinga okushisa aphezulu kanye namazinga kasawoti atholakala emisebenzini yasensimini kawoyela.
   • I-CMC: I-Sodium carboxymethyl cellulose nayo ibonisa izakhiwo zokuguqulwa kwe-viscosity kanye ne-rheology, kodwa i-viscosity yayo ivame ukuba phansi uma iqhathaniswa ne-PAC. I-CMC yakha izixazululo ezizinzile kakhulu nezingezona ezepulasitiki, okwenza ifaneleke ezinhlotsheni eziningi zezicelo, okuhlanganisa ukudla, izimonyo, kanye nemithi.
4. Izicelo:
   • I-PAC: I-polyanionic cellulose isetshenziswa kakhulu embonini kawoyela negesi njenge-ejenti yokulawula ukuhlunga, i-rheology modifier, kanye ne-fluid loss reducer kuma-drilling fluids. Iphinde isetshenziswe kwezinye izinhlelo zokusebenza zezimboni ezifana nezinto zokwakha kanye nokulungiswa kwemvelo.
   • I-CMC: I-Sodium carboxymethyl cellulose inezinhlelo zokusebenza ezahlukahlukene ezimbonini ezahlukahlukene, okuhlanganisa ukudla neziphuzo (njengesithambisi kanye nesiqinisi), imithi (njengesihlanganisi kanye nesihlukanisi), imikhiqizo yokunakekela umuntu (njengesilungisi se-rheology), izindwangu (njenge-ejenti yokulinganisa), kanye nokukhiqizwa kwephepha (njengesengezo sephepha).

kuyilapho kokubili i-polyanionic cellulose (PAC) kanye ne-sodium carboxymethyl cellulose (CMC) kuyizinto ezitholakala ku-cellulose ezinezakhiwo ze-anionic kanye nezicelo ezifanayo kwezinye izimboni, zinemehluko ohlukile ngokwesakhiwo samakhemikhali, izakhiwo, kanye nezicelo ezithile. I-PAC isetshenziswa kakhulu embonini kawoyela negesi, kuyilapho i-CMC ithola izicelo ezibanzi ekudleni, emithini yemithi, ekunakekelweni komuntu siqu, ezindwangu, nakwezinye izimboni.
