Polyanionic Cellulose (PAC)

Polyanionic Cellulose (PAC) ke motsoako oa selulose o qhibilihang ka metsing o sebelisoang haholo liindastering tse fapaneng bakeng sa thepa ea ona ea rheological le matla a ho laola tahlehelo ea mokelikeli. E tsoa ho selulose ea tlhaho ka letoto la liphetoho tsa lik'hemik'hale, tse hlahisang polima e nang le litefello tsa anionic haufi le mokokotlo oa cellulose. Mona ke lintlha tsa bohlokoa mabapi le Polyanionic Cellulose:

1. Sebopeho sa Lik'hemik'hale: PAC e tšoana ka lik'hemik'hale le selulose empa e na le lihlopha tsa anionic carboxyl (-COO-) tse khomaretsoeng mokokotlong oa cellulose. Lihlopha tsena tsa anionic li fana ka PAC ka thepa ea eona e ikhethang, ho kenyeletsoa ho qhibiliha ha metsi le bokhoni ba ho sebelisana le limolek'hule tse ling ka litšebelisano tsa motlakase.
2. Mosebetsi: PAC e sebelisoa haholo-holo e le mofetoleli oa rheology le moemeli oa ho laola tahlehelo ea mokelikeli ho metsi a cheka bakeng sa ho hlahloba oli le khase. E thusa ho laola li-viscosity le thepa ea phallo ea maro a ho cheka, ho ntlafatsa ho emisoa ha lintho tse tiileng, le ho fokotsa tahlehelo ea mokelikeli hore e be sebopeho sa porous. PAC e boetse e ntlafatsa ho hloekisoa ha mekoti le ho thibela ho se tsitse ha seliba nakong ea ho cheka.
3. Likopo: Tšebeliso e kholo ea PAC ke indastering ea oli le khase, moo e sebelisoang ho cheka metsoako ea seretse. E sebelisoa hangata ka har'a metsi a cheka a thehiloeng metsing le ka oli ho ntlafatsa ts'ebetso le ho netefatsa ts'ebetso e nepahetseng ea ho cheka. PAC e boetse e sebelisoa liindastering tse ling bakeng sa ho tenya, ho tsitsisa, le ho boloka metsi ka mekhoa e fapaneng.
4. Mefuta: PAC e fumaneha ka limaraka le li-viscosity tse fapaneng ho lumellana le litlhoko tse khethehileng tsa kopo. Mefuta e tloaelehileng ea PAC e kenyelletsa limaraka tse tlase tsa viscosity bakeng sa taolo ea tahlehelo ea mokelikeli le limaraka tse phahameng tsa viscosity bakeng sa phetoho ea viscosity le ho emisoa ha lintho tse tiileng marong a ho cheka. Khetho ea mofuta oa PAC e ipapisitse le lintlha tse kang maemo a seliba, tikoloho ea ho cheka, le lintlha tsa mokelikeli.
5. Melemo: Tšebeliso ea PAC e fana ka melemo e mengata ts'ebetsong ea ho cheka, ho kenyelletsa:
   • Taolo e sebetsang ea tahlehelo ea mokelikeli ho boloka botsitso ba hantle le ho thibela tšenyo ea sebopeho.
   • Ho emisoa ho ntlafalitsoeng ha li-drill cuttings le lintho tse tiileng, tse lebisang ho hloekisoeng ha likoti hantle.
   • Matla a rheological a ntlafalitsoeng, a netefatsa ts'ebetso e tsitsitseng ea mokelikeli tlas'a maemo a fapaneng a tlase.
   • Ho tsamaellana le li-additives tse ling le likarolo tsa mokelikeli oa ho cheka, ho nolofatsa mokhoa oa ho hlophisa le ho ntlafatsa.
6. Mehopolo ea Tikoloho: Le hoja PAC e sebelisoa haholo marong a ho cheka, phello ea eona ea tikoloho le ho senyeha ha bioloji li lokela ho nkoa. Boiteko bo ntse bo tsoela pele ba ho hlahisa mekhoa e meng e se nang tikoloho ho PAC le ho fokotsa sebaka sa eona sa tikoloho ts'ebetsong ea ho cheka.

Polyanionic Cellulose (PAC) ke tlatsetso e feto-fetohang le ea bohlokoa indastering ea oli le khase, moo e bapalang karolo ea bohlokoa ho ntlafatseng ts'ebetso ea mokelikeli oa ho cheka le ho netefatsa ts'ebetso e nepahetseng ea ho cheka. Lintho tsa eona tse ikhethang tsa rheological, bokhoni ba ho laola tahlehelo ea mokelikeli, le ho lumellana ho etsa hore e be karolo ea bohlokoa ho cheka metsoako ea seretse.
