Polyanionic Cellulose High Viscosity (PAC HV)

High viscosity polyanionic cellulose (PAC-HV) ke mofuta o tsoang ho cellulose o sebelisoang haholo joalo ka setlolo sa viscosifier le tlatsetso ea taolo ea tahlehelo ea mokelikeli liindastering tse fapaneng, haholo ho cheka le ho phethela maro bakeng sa ho lekola oli le khase. Mona ke kakaretso ea PAC-HV:

1. Sebopeho: PAC-HV e tsoa ho selulose ea tlhaho ka ho fetola lik'hemik'hale ho hlahisa lihlopha tsa carboxymethyl le ho ntlafatsa ho qhibiliha ha eona metsing. Tekanyo ea ho kenya sebaka le boima ba limolek'hule e khetholla viscosity le litšobotsi tsa ts'ebetso tsa PAC-HV.

2. Mosebetsi:

• Viscosifier: PAC-HV e fana ka viscosity e phahameng ho litharollo tse nang le metsi, e etsa hore e sebetse hantle bakeng sa ho tenya maro a ho cheka le ho ntlafatsa bokhoni ba bona ba ho jara likheo tse chekiloeng.
• Taolo ea Tahlehelo ea Mekelikeli: PAC-HV 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-HV e susumetsa boitšoaro ba ho phalla le thepa ea rheological ea maro a ho cheka, e matlafatsa ho fanyeha ha lintho tse tiileng le ho fokotsa ho lula.

3. Likopo:

• Ho Cheka Oli le Khase: PAC-HV e sebelisoa haholo marong a ho cheka a thehiloeng metsing bakeng sa tšebetso ea ho cheka lebopong le kantle ho naha. E thusa ho boloka botsitso ba hantle, ho thibela tšenyo ea sebopeho, le ho nolofatsa ts'ebetso e nepahetseng ea ho cheka.
• Kaho: PAC-HV e hiriloe e le sekontiri se setenya le se bolokang metsi meralong ea samente joalo ka li-grouts, slurries, le mortars tse sebelisoang lits'ebetsong tsa kaho.
• Meriana ea Meriana: Meetsong ea meriana, PAC-HV e sebetsa e le se tlamellang, se senyang, le se laolang ho lokolloa ha letlapa le li-capsules.

4. Thepa:

• Viscosity e phahameng: PAC-HV e bonts'a viscosity e phahameng ka tharollo, e fana ka thepa e matla ea ho tenya esita le maemong a tlase.
• Ho qhibiliha ha Metsi: PAC-HV e qhibiliha habonolo ka metsing, e lumellang ho kenngoa habonolo mecheng ea metsi ntle le tlhokahalo ea lihlapolli tse eketsehileng kapa li-disperpers.
• Thermal Stability: PAC-HV e boloka viscosity ea eona le litšobotsi tsa ts'ebetso holim'a mefuta e mengata ea mocheso e kopanang le ho cheka le lisebelisoa tse ling tsa indasteri.
• Mamello ea Letsoai: PAC-HV e bonts'a tšebelisano e ntle le maemo a holimo a letsoai le matsoai a atisang ho kopana le tikoloho ea libaka tsa oli.

5. Boleng le Litlhaloso:

• Lihlahisoa tsa PAC-HV 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 bokhuts'oane, PAC-HV ke tlatsetso e fapaneng le e sebetsang e nang le viscosity e phahameng, taolo ea tahlehelo ea mokelikeli, le thepa ea rheological, e e etsang hore e be ea bohlokoa lits'ebetsong tse fapaneng tsa indasteri, haholo ts'ebetsong ea ho cheka oli le khase. Ho tšepahala ha eona, ts'ebetso, le ho lumellana le lisebelisoa tse ling li kenya letsoho ts'ebelisong ea eona e atileng libakeng tse phephetsang tsa ho cheka.
