Polyanionic cellulose, PAC HV & LV

I-Polyanionic cellulose (PAC) yipolymer eguquguqukayo esetyenziswa kumashishini ahlukeneyo, kubandakanya ukugrumba ioyile, amayeza, ukwakhiwa, kunye nokutya. I-PAC ifumaneka kumabakala ahlukeneyo e-viscosity, kuquka i-viscosity ephezulu (HV) kunye ne-viscosity ephantsi (LV), nganye inezicelo ezithile kunye neempawu:

1. Polyanionic Cellulose (PAC):
   • I-PAC iphuma kwi-cellulose enyibilikayo emanzini ephuma kwiselulosi yendalo ngokuguqulwa kweekhemikhali, ngokwesiqhelo ngokwazisa amaqela e-carboxymethyl kumqolo we-cellulose.
   • Isetyenziswa ngokubanzi njenge-rheology modifier, i-viscosifier, kunye ne-arhente yokulawula ukulahleka kwamanzi kwiinkqubo ezisekelwe emanzini.
   • I-PAC iphucula iipropati zolwelo ezifana ne-viscosity, ukunqunyanyiswa kwezinto eziqinileyo, kunye nokulawulwa kwelahleko yolwelo kwizicelo ezahlukeneyo.
2. I-PAC HV (I-Viscosity ephezulu):
   • I-PAC HV ibakala le-polyanionic cellulose ene-viscosity ephezulu.
   • Isetyenziselwa ukugrumba ulwelo lweoyile kunye negesi yokuhlola ukubonelela nge-viscosity ephezulu kunye nolawulo olubalaseleyo lokulahleka kolwelo.
   • I-PAC HV iluncedo kakhulu kwiimeko zokomba ezicela umngeni apho ukugcinwa kozinzo lwequla kunye nokuthwala umthamo wokusika okugrunjiweyo kubalulekile.
3. I-PAC LV (I-Viscosity ephantsi):
   • I-PAC LV ibakala le-polyanionic cellulose ene-viscosity ephantsi.
   • Ikwasetyenziselwa ukugrumba ulwelo kodwa iyakhethwa xa i-viscosity ephakathi kunye nokulawulwa kokulahleka kolwelo kufuneka.
   • I-PAC LV inikezela nge-viscosification kunye neempawu zokulawula ukulahleka kwamanzi ngelixa igcina i-viscosity ephantsi xa kuthelekiswa ne-PAC HV.

Usetyenziso:

• I-Oli kunye neGesi yoKwemba: I-PAC HV kunye ne-LV zombini izongezo eziyimfuneko kumanzi okugaya asekelwe emanzini, anegalelo kulawulo lwe-viscosity, ulawulo lokulahlekelwa kwamanzi, kunye nokuguqulwa kwe-rheology.
• Ulwakhiwo: I-PAC LV ingasetyenziswa njengento etyebisayo kunye nokugcina amanzi kwimixube yesamente efana neegrouts, islurries, kunye nedaka ezisetyenziswa kwizicelo zokwakha.
• I-Pharmaceuticals: Zombini i-PAC HV kunye ne-LV inokusebenza njengezibophelelo, i-disintegrants, kunye ne-controlled-release agents kwi-tablet kunye ne-capsule formulations kwi-pharmaceuticals.

Isishwankathelo, i-polyanionic cellulose (PAC) kuzo zombini i-viscosity ephezulu (i-PAC HV) kunye ne-viscosity ephantsi (i-PAC LV) amabakala adlala indima ebalulekileyo kumashishini ahlukeneyo, kubandakanywa ukugaya ioli, ukwakhiwa, kunye namayeza, ukubonelela ngolawulo lwe-rheological, ukuguqulwa kwe-viscosity, kunye nolwelo. iipropati zokulawula ilahleko. Ukukhethwa kwebakala lePAC kuxhomekeke kwiimfuno ezithile zesicelo kunye neempawu zokusebenza ezinqwenelekayo.
