Ukuthelekiswa kwePropati ye-Fluid Loss Resistance Property ye-Polyanionic cellulose Eveliswe yiNkqubo yeDough kunye neNkqubo ye-Slurry

I-Polyanionic cellulose (PAC) yipolymer enyibilikayo emanzini ephuma kwi-cellulose kwaye isetyenziswa ngokuqhelekileyo njengesongezo sokulawula ukulahleka kwamanzi kwiincindi zokomba ezisetyenziselwa ukuhlola ioli kunye negesi. Iindlela ezimbini eziphambili zokuvelisa iPAC yinkqubo yentlama kunye nenkqubo yodaka. Nalu uthelekiso lwepropathi yokumelana nolwelo lwePAC oluveliswe zezi nkqubo zimbini:

1. Inkqubo yoHlama:
   • Indlela yokuvelisa: Kwinkqubo yentlama, i-PAC iveliswa ngokuphendula i-cellulose kunye ne-alkali, njenge-sodium hydroxide, ukwenza intlama ye-alkaline cellulose. Le ntlama iphinda iphendule nge-chloroacetic acid ukwazisa amaqela e-carboxymethyl kwi-cellulose backbone, ekhokelela kwi-PAC.
   • Ubungakanani besuntswana: IPAC eveliswa yintlama ikholisa ukuba nobungakanani besuntswana elikhulu kwaye inokuqulatha agglomerates okanye aggregates of PAC particles.
   • I-Fluid Loss Resistance: I-PAC eveliswa yinkqubo yentlama ibonakalisa ukuxhathisa ilahleko entle yolwelo kulwelo lokomba. Nangona kunjalo, ubungakanani bamasuntswana amakhulu kunye nobukho obunokwenzeka be-agglomerates bunokubangela ukuhanjiswa okucothayo kunye nokusasazeka kulwelo olusekwe emanzini, olunokuchaphazela ukusebenza kolawulo lokulahleka kolwelo, ngakumbi kwimeko yobushushu obuphezulu kunye noxinzelelo oluphezulu.
2. Inkqubo yoLudaka:
   • Indlela yokuvelisa: Kwinkqubo ye-slurry, i-cellulose ihlakazwa kuqala emanzini ukuze yenze i-slurry, ethi iphendule nge-sodium hydroxide kunye ne-chloroacetic acid ukuvelisa i-PAC ngqo kwisisombululo.
   • Ubungakanani beNcam: I-PAC eveliswa yinkqubo yodaka iqhele ukuba nobungakanani besuntswana elincinci kwaye isasazwe ngokulinganayo kwisisombululo xa kuthelekiswa nePAC eveliswa yinkqubo yentlama.
   • I-Fluid Loss Resistance: I-PAC eveliswa yinkqubo yodaka ithande ukubonisa ukuxhathisa ilahleko yolwelo olubalaseleyo kulwelo lokomba. Ubungakanani beqhekeza elincinci kunye nokusabalalisa okufanayo kubangela ukuhanjiswa ngokukhawuleza kunye nokusabalalisa kumanzi okugaya asekelwe emanzini, okukhokelela ekuphuculeni ukusebenza kokulawulwa kokulahleka kwamanzi, ngakumbi kwiimeko ezinzima zokugaya.

zombini PAC eveliswe inkqubo intlama kunye PAC eveliswe yinkqubo ludaka inokubonelela olusebenzayo ulwelo ilahleko ukuxhathisa kulwelo kusombiwa. Nangona kunjalo, iPAC eveliswe yinkqubo ye-slurry inokubonelela ngezibonelelo ezithile, ezifana nokukhawuleza kwe-hydration kunye nokusasazwa, okukhokelela ekusebenzeni okuphuculweyo kokulawulwa kwelahleko, ngakumbi kwindawo yobushushu obuphezulu kunye noxinzelelo oluphezulu lokomba. Ekugqibeleni, ukhetho phakathi kwezi ndlela zimbini zokuvelisa lunokuxhomekeka kwiimfuno ezithile zokusebenza, ukuqwalaselwa kweendleko, kunye nezinye izinto ezifanelekileyo kwisicelo se-drilling fluid.
