PAC (Polyanionic Cellulose)

Polyanionic cellulose (PAC) ke polima e qhibilihang ka metsi e tsoang ho selulose, motsoako oa tlhaho o fumanoang limela. PAC e sebelisoa haholo liindastering tse fapaneng, ho kenyeletsoa le ho cheka oli, ka lebaka la thepa ea eona e ikhethang le ho feto-fetoha ha maemo. Boemong ba ho cheka oli, PAC e sebetsa mesebetsi e 'maloa ea bohlokoa ho maro a ho cheka:

1. Viscosification: PAC e sebelisoa haholo-holo e le viscosifier ka maro a ho cheka metsi. E thusa ho eketsa viscosity ea mokelikeli, ho ntlafatsa bokhoni ba eona ba ho emisa le ho tsamaisa li-cuttings tse chekiloeng le lintho tse ling tse tiileng holimo. Sena se thusa ho boloka botsitso ba seliba le ho thibela ho putlama ha lesoba.
2. Taolo ea Tahlehelo ea Mekelikeli: PAC e etsa kuku e tšesaane e ke keng ea qoelisoa maboteng a seliba, e fokotsang tahlehelo ea mokelikeli oa ho cheka sebakeng se potolohileng. Sena se thusa ho boloka bots'epehi ba wellbore, ho thibela tšenyo ea sebopeho, le ho ntlafatsa bokhoni ba ho cheka.
3. Phetoho ea Rheology: PAC e susumetsa boits'oaro ba phallo le thepa ea rheological ea maro a ho cheka, ho ntlafatsa ho emisoa ha lintho tse tiileng le ho fokotsa ho tsitsa. Sena se tiisa ts'ebetso e tsitsitseng ea mokelikeli oa ho phunya tlas'a maemo a fapaneng a tlase.
4. Ho Hloekisa Likoti: Ka ho eketsa viscosity le bokhoni ba ho jara ba mokelikeli oa ho cheka, PAC e ntlafatsa ts'ebetso ea ho hloekisa mekoti, e thusa ho tlosoa ha likheo tse chekiloeng le litšila tse tsoang selibeng.
5. Thempereichara le Botsitso ba Letsoai: PAC e bonts'a mamello e phahameng ea mocheso le letsoai, e boloka ponahalo ea eona le litšoaneleho tsa ts'ebetso holim'a mefuta e mengata ea mocheso le letsoai le fumanoang mesebetsing ea ho cheka.
6. E Sekehela Tikoloho: PAC e nkiloe mehloling e nchafalitsoeng e thehiloeng ho limela 'me e khona ho senyeha, ho e etsa hore e se ke ea silafatsa tikoloho ebile e loketse ho sebelisoa libakeng tse chekoang haholo ke tikoloho.

PAC e fumaneha ka limaraka tse fapaneng le litlhaloso tse lumellanang le litlhoko tse khethehileng tsa mokelikeli oa ho cheka le maemo a ts'ebetso. Mehato ea taolo ea boleng e netefatsa botsitso le ho latela maemo a indasteri, ho kenyeletsoa lintlha tsa API (American Petroleum Institute) bakeng sa ho cheka li-additives tsa mokelikeli.

Ka bokhutšoanyane, polyanionic cellulose (PAC) ke tlatsetso ea bohlokoa ho metsi a cheka a thehiloeng metsing bakeng sa ho hlahloba oli le khase, ho fana ka viscosification, taolo ea tahlehelo ea mokelikeli, phetoho ea rheology, le lisebelisoa tse ling tsa bohlokoa tse tlatsetsang ts'ebetsong e sebetsang hantle le e atlehileng ea ho cheka.
