Polyanionic cellulose

Polyanionic cellulose (PAC) ke motsoako oa cellulose o qhibilihang ka metsing o fumanang tšebeliso e atileng lits'ebetsong tse fapaneng tsa indasteri, haholo indastering ea ho cheka oli le khase. Mona ke kakaretso ea selulose ea polyanionic:

1. Sebopeho: Polyanionic cellulose e tsoa ho selulose, polymer ea tlhaho e fumanoang limela, ka ho fetola lik'hemik'hale. Lihlopha tsa carboxymethyl li kenngoa mokokotlong oa cellulose, li e fa thepa ea anionic (e qosoang hampe).

2. Mosebetsi:

• Viscosifier: PAC e sebelisoa haholo-holo joalo ka viscosifier marong a chekang metsi. E fana ka viscosity ho mokelikeli, ho ntlafatsa bokhoni ba eona ba ho emisa le ho tsamaisa li-cuttings tse chekiloeng holimo.
• Taolo ea Tahlehelo ea Mekelikeli: PAC e etsa kuku e tšesaane, e ke keng ea qoelisoa leboteng la borehole, e fokotsang tahlehelo ea mokelikeli sebopehong le ho boloka botsitso ba seliba.
• Rheology Modifier: PAC e susumetsa boits'oaro ba phallo le thepa ea rheological ea maro a ho cheka, e ntlafatsa ho emisoa ha lintho tse tiileng le ho fokotsa ho tsitsa.

3. Likopo:

• Ho Cheka Oli le Khase: PAC ke sehlomathiso se ka sehloohong sa maro a chekang a thehiloeng metsing a sebelisoang ho phuputsong le tlhahisong ea oli le khase. E thusa ho laola viscosity, tahlehelo ea mokelikeli, le rheology, ho netefatsa ts'ebetso e nepahetseng ea ho cheka le botsitso ba seliba.
• Kaho: PAC e sebelisoa e le ntho e thibelang metsi le ho boloka metsi mefuteng ea samente joalo ka li-grouts, slurries le mortars tse sebelisoang lits'ebetsong tsa kaho.
• Meriana: Litlhahlobong tsa meriana, PAC e sebetsa e le se tlamellang, se senyang, le se laolang ho lokolloa ha letlapa le li-capsules.

4. Thepa:

• Ho qhibiliha ha Metsi: PAC e qhibiliha habonolo ka metsing, e lumellang ho kenngoa habonolo mecheng ea metsi ntle le tlhokahalo ea lihlapolli tse eketsehileng kapa li-disperpers.
• Botsitso bo Phahameng: PAC e bonts'a botsitso bo phahameng ba mocheso le lik'hemik'hale, e boloka litšobotsi tsa eona tsa ts'ebetso ho feta mefuta e mengata ea mocheso le maemo a pH.
• Mamello ea Letsoai: PAC e bonts'a tšebelisano e ntle le maemo a holimo a letsoai le matsoai a atisang ho kopana le libaka tsa oli.
• Biodegradability: PAC e nkiloe mehloling e nchafalitsoeng e thehiloeng ho limela 'me e khona ho senyeha, ho e etsa hore e boloke tikoloho.

5. Boleng le Litlhaloso:

• Lihlahisoa tsa PAC li fumaneha ka limaraka tse fapaneng le litlhaloso tse etselitsoeng lits'ebetso tse ikhethileng le litlhoko tsa 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 ke tlatsetso e fapaneng le e sebetsang e nang le viscosifying, taolo ea tahlehelo ea mokelikeli, le thepa ea rheological, e etsang hore e be ea bohlokoa bakeng sa lits'ebetso tse fapaneng tsa indasteri, haholo indastering ea ho cheka oli le khase. Ho tšepahala ha eona, ts'ebetso ea eona, le ho lumellana ha eona le tikoloho li kenya letsoho ts'ebelisong ea eona e pharaletseng libakeng tse phephetsang tsa ho cheka.
