I-Polyanionic cellulose, i-PAC HV & LV

I-Polyanionic cellulose (PAC) iyi-polymer eguquguqukayo esetshenziswa ezimbonini ezahlukahlukene, kufaka phakathi ukumba uwoyela, ezemithi, ezokwakha, nokudla. I-PAC itholakala kumabanga ahlukene e-viscosity, okuhlanganisa i-viscosity ephezulu (HV) kanye ne-viscosity ephansi (LV), ngalinye linezinhlelo zokusebenza ezithize nezici:

  1. I-Polyanionic Cellulose (PAC):
    • I-PAC iphuma ku-cellulose encibilika emanzini etholakala ku-cellulose yemvelo ngokuguqulwa kwamakhemikhali, ngokuvamile ngokwethula amaqembu e-carboxymethyl kumgogodla we-cellulose.
    • Isetshenziswa kabanzi njenge-rheology modifier, i-viscosifier, ne-ejenti yokulawula ukulahlekelwa uketshezi kumasistimu asekelwe emanzini.
    • I-PAC ithuthukisa izinto eziwuketshezi ezifana ne-viscosity, ukumiswa kwezinto eziqinile, nokulawulwa kokulahlekelwa uketshezi ezinhlelweni ezihlukahlukene.
  2. I-PAC HV (I-Viscosity ephezulu):
    • I-PAC HV iyibanga le-polyanionic cellulose ene-viscosity ephezulu.
    • Isetshenziselwa ukumba uketshezi ukuhlola uwoyela negesi ukuze kunikeze i-viscosity ephezulu kanye nokulawulwa okuhle kakhulu kokulahlekelwa uketshezi.
    • I-PAC HV iwusizo ikakhulukazi ezimeni zokumba eziyinselele lapho ukugcinwa kokuzinza kwe-wellbore kanye nokuthwala umthamo wokusikwa okumbayo kubalulekile.
  3. I-PAC LV (I-Viscosity Ephansi):
    • I-PAC LV iyibanga le-polyanionic cellulose ene-viscosity ephansi.
    • Ibuye isetshenziselwe uketshezi lokumba kodwa iyathandwa uma kudingeka i-viscosity emaphakathi kanye nokulawulwa kokulahlekelwa uketshezi.
    • I-PAC LV inikezela nge-viscosification kanye nezakhiwo zokulawula uketshezi ngenkathi igcina i-viscosity ephansi uma iqhathaniswa ne-PAC HV.

Izicelo:

  • Ukumba Uwoyela Negesi: I-PAC HV ne-LV zombili izithasiselo 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 ekwakhiweni kukasimende njengama-grouts, ama-slurries, nama-mortar asetshenziswa ezinhlelweni zokwakha.
  • Ezemithi: Kokubili i-PAC HV ne-LV zingasebenza njengezibopheli, ezihlukanisayo, nama-ejenti akhishwayo okulawulwayo ekwakhiweni kwethebhulethi namakhephuseli kwezemithi.

Kafushane, i-polyanionic cellulose (PAC) kuwo womabili amabanga aphezulu e-viscosity (PAC HV) kanye ne-viscosity ephansi (PAC LV) idlala indima ebalulekile ezimbonini ezahlukahlukene, okuhlanganisa ukumba uwoyela, ukwakhiwa, kanye nemithi, ehlinzeka ngokulawula kwe-rheological, ukuguqulwa kwe-viscosity, noketshezi. izakhiwo zokulawula ukulahlekelwa. Ukukhethwa kwebanga le-PAC kuncike ezidingweni ezithile zohlelo lokusebenza nezici zokusebenza ezifiswayo.
