Ukuqhathaniswa kwempahla yokumelana nokulahleka kwe-fluid ye-polyanionic celvulose ekhiqizwa yinqubo yenhlama kanye nenqubo ye-slurry

I-Polyanionic Cellulose (PAC) iyi-polymer esolulekayo enamanzi etholakala ku-cellulose futhi isetshenziswa kakhulu njengesengezo sokulawula ukulahleka koketshezi ku-drive fluids esetshenziswa e-oyili nokuhlola igesi. Izindlela ezimbili eziphambili zokukhiqiza i-PAC yinqubo yenhlama kanye nenqubo ebabayo. Nakhu ukuqhathanisa impahla yokumelana noketshezi ye-PAC ekhiqizwa yilezi zinqubo ezimbili:

1. Inqubo yenhlama:
   • Indlela yokukhiqiza: Enqubweni yenhlama, i-PAC ikhiqizwa ngokuphendula i-cellulose nge-alkali, efana ne-sodium hydroxide, ukwakha inhlama ye-alkali ye-alkalile. Le nhlama iphinde yaphendulwa nge-chlororoacetic acid ukwethula amaqembu e-carboxymethyl e-cellulose backbone, okuholela ku-PAC.
   • Ubukhulu bezinhlayiyana: I-PAC ekhiqizwa yinqubo yenhlama imvamisa inosayizi omkhulu wezinhlayiyana futhi ingaqukatha ama-agglomerates noma ama-aggregates ama-PA PACKLES.
   • Ukumelana nokulahleka koketshezi: I-PAC ekhiqizwa yinqubo yenhlama ngokuvamile ibonisa ukumelana nokulahleka okuhle koketshezi kumanzi okumba. Kodwa-ke, usayizi omkhulu wezinhlayiyana kanye nokuba khona kwama-agglomerates kungahle kuholele ekuhambeni kwe-hydration kanye nokuhlakazeka kumanzi wokulahla amanzi asuselwa emanzini, ikakhulukazi ezimweni zokushisa eziphakeme kanye nezingcindezi eziphakeme.
2. Inqubo yeSlurry:
   • Indlela yokukhiqiza: Enqubweni yeSlurry, i-cellulose ihlakazeka okokuqala emanzini ukuze kwakhiwe i-Slurry, esele esenziwa nge-sodium hydroxide kanye ne-chlororoacetic acid ukukhiqiza ngokuqondile ngesisombululo.
   • Ubukhulu bezinhlayiya: I-PAC ekhiqizwa yinqubo ye-slurry imvamisa inosayizi omncane wezinhlayiyana futhi ihlakazeke ngendlela efanayo ngokuqhathaniswa ne-PAC ekhiqizwa yinqubo yenhlama.
   • Ukumelana nokulahleka koketshezi: I-PAC ekhiqizwa yinqubo ye-slurry ivame ukukhombisa ukumelana nokulahlekelwa koketshezi okuhle kakhulu ku-Dripled fluid. Ubukhulu obuncane bezinhlayiyana kanye nomfaniswano wokuhambisa ofanayo ku-hydration esheshayo kanye nokuhlakazeka emanzini okumba okususelwa emanzini, okuholela ekusebenzeni kokulawulwa kokulahlekelwa kokulahleka koketshezi, ikakhulukazi ezimweni zokumba ezilinselele.

Kokubili i-PAC ekhiqizwa yinqubo yenhlama kanye ne-PAC ekhiqizwa yinqubo ye-slurry kunganikeza ukumelana nokulahleka koketshezi okusebenzayo kumanzi okumba uketshezi. Kodwa-ke, i-PAC ekhiqizwa yinqubo ye-slurry inganikezela ngezinzuzo ezithile, njenge-hydration ethile kanye nokusakazeka, okuholela ekusebenzeni kokulawulwa kokulahlekelwa koketshezi, ikakhulukazi ezindaweni zokushisa eziphakeme nasezingeni eliphakeme. Ekugcineni, ukukhetha phakathi kwalezi zindlela ezimbili zokukhiqiza kungahle kuncike kwizidingo ezithile zokusebenza, ukucatshangelwa kwezindleko, nezinye izinto eziphathelene nohlelo lokusebenza lwe-drive fluid.
