Polyanionic cellulose LV HV

Polyanionic cellulose (PAC) ke polima e qhibilihang ka metsing e tsoang ho selulose.E sebelisoa haholo indastering ea oli le khase e le motsoako oa mokelikeli oa ho cheka, moo o sebelisetsoang ho laola tahlehelo ea mokelikeli, ho eketsa viscosity, le ho ntlafatsa thibelo ea shale.PAC e fumaneha ka limaraka tse fapaneng, ka likhato tse fapaneng tsa sebaka le boima ba molek'hule.Limaraka tse peli tse tloaelehileng tsa PAC ke viscosity e tlase (LV) le viscosity e phahameng (HV) PAC.

PAC LV e na le boima bo tlase ba limolek'hule le boemo bo tlase ba ho nka sebaka.E sebelisoa e le moemeli oa ho laola ho hloekisa le ho fetola rheology ka maro a ho cheka.LV-PAC e na le ho qhibiliha ha metsi hantle 'me e sebetsa maemong a tlase.E boetse e sebelisoa e le viscosifier ka li-slurries tsa samente le joalo ka stabilizer ho li-emulsions.

PAC HV, ka lehlakoreng le leng, e na le boima ba molek'hule bo phahameng le boemo bo phahameng ba ho nka sebaka ho feta LV-PAC.E sebelisoa e le sesebelisoa sa mantlha sa viscosifier le se laolang tahlehelo ea mokelikeli marong a ho cheka.HV-PAC e ka boela ea sebelisoa e le viscosifier ea bobeli hammoho le li-polymer tse ling.E na le mamello e phahameng ea letsoai le mocheso, 'me e sebetsa hantle libakeng tse phahameng.

Ka bobeli LV-PAC le HV-PAC ke polyanionic, ho bolelang hore li na le tefiso e mpe.Tefiso ena e ba etsa hore ba atlehe ho laola tahlehelo ea mokelikeli ka ho etsa kuku e sefang selibeng.Tefiso e mpe e boetse e etsa hore e atlehe ho thibela hydration ea shale le ho hasana.PAC e ka boela ea ntlafatsa botsitso ba wellbore ka ho thibela ho falla ha likotlo le likaroloana tsa letsopa.

Qetellong, polyanionic cellulose (PAC) ke polima e nang le mefuta e mengata e sebelisoang indastering ea oli le khase e le motsoako oa mokelikeli oa ho cheka.LV-PAC le HV-PAC ke limaraka tse peli tse tloaelehileng tsa PAC tse sebelisetsoang merero e fapaneng.LV-PAC e sebelisoa e le sesebelisoa sa ho laola ho hloekisa le ho fetola rheology, ha HV-PAC e sebelisoa e le mochine o ka sehloohong oa viscosifier le ho laola tahlehelo ea mokelikeli.Limaraka ka bobeli tsa PAC li na le polyanionic 'me li sebetsa hantle ho laola tahlehelo ea mokelikeli le ho thibela ho phalla ha shale le ho hasana.
