Ukuqhathaniswa kwe-Fluid Loss Resistance Property ye-Polyanionic cellulose Ekhiqizwe Inqubo Yenhlama kanye Nenqubo Ye-Slurry

I-Polyanionic cellulose (PAC) i-polymer encibilika emanzini etholakala ku-cellulose futhi ivamise ukusetshenziswa njengesithasiselo sokulawula ukulahlekelwa uketshezi oketshezini lokumba olusetshenziswa ekuhloleni uwoyela negesi. Izindlela ezimbili eziyinhloko zokukhiqiza i-PAC inqubo yenhlama kanye nenqubo ye-slurry. Nasi isiqhathaniso sendawo ye-PAC yokumelana nokulahlekelwa uketshezi ekhiqizwa yilezi zinqubo ezimbili:

1. Inqubo Yenhlama:
   • Indlela Yokukhiqiza: Enqubweni yenhlama, i-PAC ikhiqizwa ngokuphendula i-cellulose nge-alkali, njenge-sodium hydroxide, ukwenza inhlama ye-alkaline cellulose. Le nhlama ibe isisabela nge-chloroacetic acid ukwethula amaqembu e-carboxymethyl kumgogodla we-cellulose, okuholela ku-PAC.
   • Usayizi Wezinhlayiyana: I-PAC ekhiqizwa inqubo yenhlama ngokuvamile inosayizi wezinhlayiyana ezinkulu futhi ingase iqukathe ama-agglomerates noma ama-aggregate ezinhlayiyana ze-PAC.
   • I-Fluid Loss Resistance: I-PAC ekhiqizwa inqubo yenhlama ngokuvamile ibonisa ukumelana nokulahlekelwa uketshezi oketshezini lokumba. Nokho, ubukhulu bezinhlayiyana ezinkulu kanye nokuba khona okungaba khona kwama-agglomerate kungase kubangele ukugeleza kwamanzi kancane kanye nokuhlakazeka emanzini okumba asekelwe emanzini, okungase kuthinte ukusebenza kokulawula ukulahlekelwa uketshezi, ikakhulukazi ezimweni zokushisa eziphezulu kanye nezimo eziphezulu zokucindezela.
2. Inqubo ye-Slurry:
   • Indlela Yokukhiqiza: Enqubweni ye-slurry, i-cellulose iqala ukuhlakazwa emanzini ukuze yakhe i-slurry, bese isabela nge-sodium hydroxide ne-chloroacetic acid ukukhiqiza i-PAC ngqo kwisisombululo.
   • Usayizi Wezinhlayiyana: I-PAC ekhiqizwa inqubo ye-slurry ngokuvamile inosayizi wezinhlayiyana ezincane futhi ihlakazeke ngokufanayo esixazululweni uma kuqhathaniswa ne-PAC ekhiqizwa inqubo yenhlama.
   • I-Fluid Loss Resistance: I-PAC ekhiqizwa inqubo ye-slurry ijwayele ukukhombisa ukumelana nokulahlekelwa uketshezi kuketshezi lokumba. Usayizi wezinhlayiyana ezincane kanye nokuhlakazeka okufanayo kubangela ukugeleza kwamanzi ngokushesha kanye nokuhlakazeka emanzini okumba asekelwe emanzini, okuholela ekusebenzeni okuthuthukisiwe kokulawula ukulahlekelwa uketshezi, ikakhulukazi ezimeni zokumba eziyinselele.

kokubili i-PAC ekhiqizwa inqubo yenhlama kanye ne-PAC ekhiqizwa inqubo ye-slurry inganikeza ukumelana okuphumelelayo kokulahlekelwa uketshezi emanzini okumba. Kodwa-ke, i-PAC ekhiqizwa inqubo ye-slurry ingase inikeze izinzuzo ezithile, ezifana nokugeleza kwamanzi okusheshayo nokuhlakazeka, okuholela ekusebenzeni okuthuthukisiwe kokulawula ukulahlekelwa uketshezi, ikakhulukazi ezindaweni zokumba ezinezinga lokushisa eliphezulu kanye nokucindezela okuphezulu. Ekugcineni, ukukhetha phakathi kwalezi zindlela ezimbili zokukhiqiza kungase kuncike ezidingweni ezithile zokusebenza, ukucatshangelwa kwezindleko, nezinye izici ezihambisana nokusetshenziswa koketshezi lokumba.
