Polyanionic cellulose LV HV

Polyanionic cellulose (PAC) i polymer inonyungudika mumvura inotorwa kubva muselulosi. Inoshandiswa zvakanyanya muindasitiri yemafuta uye gasi sekuwedzera kwemvura yekuchera, uko inoshandiswa kudzora kurasikirwa kwemvura, kuwedzera viscosity, uye kugadzirisa shale inhibition. PAC inowanikwa mumagiredhi akasiyana, ine madhigirii akasiyana ekutsiva uye huremu hwemamorekuru. Magiredhi maviri akajairika ePAC akaderera viscosity (LV) uye yakakwirira viscosity (HV) PAC.

PAC LV ine yakaderera molecular huremu uye yakaderera dhigirii yekutsiva. Inoshandiswa sefiltration control agent uye se rheology modifier mumvura yekuchera. LV-PAC ine yakanaka solubility mumvura uye inoshanda munzvimbo dzakaderera. Inoshandiswawo seviscosifier mune simenti slurries uye seyakagadzikana mune emulsions.

PAC HV, kune rumwe rutivi, ine huremu hwepamusoro-soro uye dhigirii repamusoro rekutsiva kupfuura LV-PAC. Inoshandiswa seyekutanga viscosifier uye yekurasikirwa kwemvura yekudzora mumiriri mukuchera zvinwiwa. HV-PAC inogona zvakare kushandiswa seyechipiri viscosifier musanganiswa nemamwe mapolymer. Iine kushivirira kwakakwirira kwemunyu uye tembiricha, uye inoshanda pamatunhu akakwirira.

Ose ari maviri LV-PAC neHV-PAC ari polyanionic, zvinoreva kuti anotakura mhosva isina kunaka. Kuchaja uku kunoita kuti vashande pakudzora kurasikirwa kwemvura nekugadzira keke resefa patsime. Kuchaja kwakashata kunoitawo kuti vashande pakudzivisa shale hydration uye kupararira. PAC inogona zvakare kuvandudza kugadzikana kwegomba nekudzivirira kutama kwefaindi uye zvidimbu zvevhu.

Mukupedzisa, polyanionic cellulose (PAC) i polymer inoshanda zvakasiyana-siyana iyo inoshandiswa muindasitiri yemafuta negasi sekuwedzera kwemvura yekuchera. LV-PAC neHV-PAC magiredhi maviri akajairwa ePAC ayo anoshandiswa kune zvakasiyana. LV-PAC inoshandiswa sefiltration control agent uye se rheology modifier, nepo HV-PAC inoshandiswa seyakanyanya viscosifier uye fluid kurasikirwa control agent. Ose magiredhi ePAC ari polyanionic uye anoshanda pakudzora kurasikirwa kwemvura uye kuvharidzira shale hydration uye kupararira.
