Polyanionic cellulosekamehla (PAC-R) ke karolo ea bohlokoa indastering ea oli le khase, haholo ts'ebetsong ea ho cheka. Polymer ena e qhibilihang ka metsi, e nkiloeng ho selulose, e sebetsa mesebetsi e sa tšoaneng ea metsi a ho cheka, e tlatsetsang katlehong le katlehong ea mesebetsi ea ho cheka. Phuputsong ena e batsi, re tla shebisisa ka har'a thepa, ts'ebeliso, ts'ebetso ea tlhahiso, phello ea tikoloho, le litebello tsa nako e tlang tsa PAC-R.

Thepa ea Polyanionic Cellulose Regular (PAC-R):

1. Sebopeho sa Lik'hemik'hale: PAC-R e tsoa ho selulose, polima ea tlhaho e fumanehang limeleng. E thehoa ka ho hlahisa lihlopha tsa anionic mokokotlong oa cellulose, e leng se etsang hore e qhibilihe ka metsing.
2. Ho qhibiliha ha Metsi: E 'ngoe ea lintho tse ka sehloohong tsa PAC-R ke ho qhibiliha ha eona ho phahameng ka metsi, e leng se lumellang ho kenngoa ha bonolo marong a ho cheka.
3. Ntlafatso ea Viscosity: PAC-R haholo-holo e sebelisoa e le viscosifier marong a ho cheka. E eketsa viscosity ea mokelikeli, e thusa ho emisa le ho tsamaisa li-cutlets tsa drill holimo.
4. Taolo ea Tahlehelo ea Mokelikeli: Mosebetsi o mong oa bohlokoa oa PAC-R ke taolo ea tahlehelo ea mokelikeli. E etsa kuku e sefang maboteng a seliba, ho thibela tahlehelo ea mokelikeli sebopehong le ho boloka botsitso ba hantle.
5. Thermal Stability: PAC-R e bonts'a botsitso ba mocheso, e etsa hore e tšoanelehe ho sebelisoa libakeng tsa ho cheka tse nang le mocheso o phahameng.
6. Mamello ea Letsoai: Sebopeho sa eona sa polyanionic se thusa PAC-R ho sebetsa ka katleho libakeng tse nang le letsoai le phahameng tse kopaneng le mesebetsi ea ho cheka kantle ho naha.

Tšebeliso ea PAC-R ho Mekelikeli ea ho Cheka:

1. Viscosifier: PAC-R e eketsoa marong a ho cheka ho eketsa viscosity, e thusang ho jara likhechana tsa ho cheka holimo le ho emisa lintho tse tiileng.
2. Setsi sa Tahlehelo ea Mekelikeli: E etsa kuku e tšesaane, e ke keng ea qoelisoa maboteng a seliba, e thibelang tahlehelo ea mokelikeli sebopehong le ho fokotsa tšenyo ea sebopeho.
3. Suspension Agent: PAC-R e thusa ho emisa lintho tse tiileng ka har'a mokelikeli oa ho cheka, ho thibela ho tsitsa le ho boloka homogeneity ea mokelikeli.
4. Friction Reducer: Ntle le ntlafatso ea viscosity, PAC-R e ka fokotsa likhohlano tsa maro a ho cheka, ea ntlafatsa ts'ebetso e akaretsang.

Mokhoa oa Tlhahiso oa PAC-R:

Tlhahiso ea PAC-R e kenyelletsa mehato e mengata:

1. Cellulose Sourcing: Cellulose, thepa e tala bakeng sa PAC-R, hangata e nkuoa ho tloha makhasi a lehong kapa lithareng tsa k'hothone.
2. Etherification: Cellulose e kena etherification, moo lihlopha tsa anionic li kenngoa mokokotlong oa cellulose. Ts'ebetso ena e etsa hore cellulose e qhibilihe ka metsing 'me e fane ka thepa ea polyanionic ho PAC-R e hlahisoang.
3. Tlhoekiso: PAC-R e kopaneng e ea hloekisoa ho tlosa litšila le ho netefatsa boleng ba sehlahisoa.
4. Ho omisa le ho Pakaletsa: PAC-R e hloekisitsoeng e omisitsoe ebe e pakeloa hore e abeloe basebelisi ba ho qetela.

Tšusumetso ea Tikoloho:

1. Biodegradability: PAC-R, e nkiloeng ho selulose, e ka senyeha tlas'a maemo a loketseng. Sena se fokotsa tšusumetso ea eona ea tikoloho ha e bapisoa le li-polymers tsa maiketsetso.
2. Taolo ea Litšila: Ho lahloa ka nepo ha maro a chekang a nang le PAC-R ho bohlokoa ho fokotsa tšilafalo ea tikoloho. Ho sebelisoa hape le kalafo ea maro a chekang ho ka fokotsa likotsi tsa tikoloho.
3. Moshoelella: Boiteko ba ho ntlafatsa ts'ebetso ea tlhahiso ea PAC-R bo kenyelletsa ho fumana selulose merung e laoloang ka mokhoa o tsitsitseng le ho kenya tšebetsong mekhoa ea tlhahiso e bolokang tikoloho.

Tebello ea Bokamoso:

1. Patlisiso le Nts'etsopele: Patlisiso e tsoelang pele e ikemiselitse ho ntlafatsa ts'ebetso le ho feto-fetoha ha maemo a PAC-R marong a ho cheka. Sena se kenyelletsa ho ntlafatsa thepa ea eona ea rheological, mamello ea letsoai, le botsitso ba mocheso.
2. Mehopolo ea Tikoloho: Lintlafatso tsa nako e tlang li ka shebana le ho fokotsa ts'ebetso ea tikoloho ea PAC-R ka ts'ebeliso ea lisebelisoa tse ka nchafatsoang le mekhoa ea tlhahiso e bolokang tikoloho.
3. Tumellano ea Taolo: Ho latela melao ea tikoloho le maemo a indasteri ho tla tsoela pele ho bopa nts'etsopele le ts'ebeliso ea PAC-R ts'ebetsong ea ho cheka.

Qetellong, polyanionic cellulose e tloaelehileng (PAC-R) e bapala karolo ea bohlokoa indastering ea oli le khase e le sesebelisoa sa viscosifier le se laolang tahlehelo ea mokelikeli marong a ho cheka. Mehaho ea eona e ikhethang, ho kenyelletsa ho qhibiliha ha metsi, ntlafatso ea viscosity, le botsitso ba mocheso, e etsa hore e be ea bohlokoa haholo lits'ebetsong tse fapaneng tsa ho cheka. Ha indasteri e ntse e tsoela pele, boiteko bo tsoelang pele ba lipatlisiso le nts'etsopele bo ikemiselitse ho ntlafatsa ts'ebetso le ts'ebetso ea tikoloho ea PAC-R, ho netefatsa hore e tsoela pele ho sebetsa mesebetsing ea ho cheka.
