I-Poly Anionic cellulose, i-PAC-LV, i-PAC-HV

I-Poly anionic cellulose (PAC) i-polymer encibilika emanzini etholakala ku-cellulose futhi yalungiswa ngamaqembu e-carboxymethyl. Isetshenziswa kakhulu ezimbonini ezahlukahlukene, okuhlanganisa ukumba uwoyela, ezokwakha, ezemithi, nokudla. I-PAC itholakala kumabanga ahlukene e-viscosity, ne-PAC-LV (Low Viscosity) kanye ne-PAC-HV (High Viscosity) okuyizinhlobonhlobo ezimbili ezivamile. Nakhu ukuhlukaniswa ngakunye:

1. I-Poly anionic Cellulose (PAC):
   • I-PAC iwukuphuma kwe-cellulose enikeza izici ze-rheological kuzixazululo ezinamanzi.
   • Isetshenziswa njenge-viscosifier, i-ejenti yokulawula ukulahlekelwa uketshezi, kanye ne-rheology modifier ezinhlobonhlobo zezinhlelo zokusebenza.
   • I-PAC iphumelela kakhulu ekulawuleni izinto eziwuketshezi ezifana ne-viscosity, ukumiswa kwezinto eziqinile, nokulahlekelwa uketshezi, okuyenza ibe yigugu ezinqubweni ezihlukahlukene zezimboni.
2. I-PAC-LV (I-Viscosity Ephansi):
   • I-PAC-LV iyibanga le-polyanionic cellulose ene-viscosity ephansi.
   • Ngokuvamile isetshenziswa lapho i-viscosity emaphakathi kanye nokulawulwa kokulahlekelwa uketshezi kuyadingeka ezinhlelweni ezifana nokumba uwoyela, ukwakhiwa, kanye nemithi.
   • I-PAC-LV ihlinzeka nge-viscosification kanye nezakhiwo zokulawula uketshezi ngenkathi igcina i-viscosity ephansi uma iqhathaniswa ne-PAC-HV.
3. I-PAC-HV (I-Viscosity ephezulu):
   • I-PAC-HV iyibanga le-polyanionic cellulose ene-viscosity ephezulu.
   • Isetshenziswa lapho i-viscosity ephezulu kanye nokulawulwa okuhle kakhulu kokulahlekelwa uketshezi kuyadingeka, ikakhulukazi ekufakweni okudingayo okufana nokubhola uwoyela negesi.
   • I-PAC-HV iphumelela kakhulu ekugcineni ukuqina kwe-wellbore, ukuthwala umthamo wokusikwa okumbayo, nokulawula ukulahleka koketshezi ezimeni zokumba eziyinselele.

Izicelo:

• Ukumba Kawoyela Negesi: Kokubili i-PAC-LV ne-PAC-HV iyizithasiselo ezibalulekile kuketshezi lokumba olusekelwe emanzini, okunikela ekulawuleni i-viscosity, ukulawulwa kokulahlekelwa uketshezi, nokuguqulwa kwe-rheology.
• Ukwakhiwa: I-PAC-LV ingase isetshenziswe njenge-ejenti yokuqina kanye nokugcina amanzi ekwenziweni kukasimende njengama-grouts, ama-slurries, nama-mortar asetshenziswa ezinhlelweni zokwakha.
• Ezemithi: I-PAC-LV ne-PAC-HV zingasebenza njengezibopheli, ezihlukanisayo, nama-ejenti akhishwayo okulawulwayo ekwakhiweni kwethebhulethi kanye nama-capsule kwezemithi.
• Imboni Yokudla: I-PAC isetshenziswa njenge-thickener, stabilizer, kanye ne-emulsifier emikhiqizweni yokudla, ehlinzeka ukuthungwa kanye nokwenza ngcono impilo yeshelufu.

Kafushane, i-polyanionic cellulose kuwo womabili amamaki e-viscosity ephansi (i-PAC-LV) kanye ne-viscosity ephezulu (PAC-HV) idlala indima ebalulekile ezimbonini ezihlukahlukene, ihlinzeka ngokulawula kwe-rheological, ukuguqulwa kwe-viscosity, kanye nezakhiwo zokulawula ukulahlekelwa koketshezi ezihambisana nezidingo ezithile zohlelo lokusebenza.
