Sodium carboxymethyl cellulose (CMC-HV) bakeng sa mokelikeli oa ho cheka

Sodium carboxymethyl cellulose high viscosity (CMC-HV) ke sehlomathiso se seng sa bohlokoa se sebelisoang marong a ho cheka, a tšoanang le polyanionic cellulose regular (PAC-R). CMC-HV ke polymer e qhibilihang ka metsing e nkiloeng ho selulose, e fetotsoeng ka lik'hemik'hale ho hlahisa lihlopha tsa carboxymethyl mokokotlong oa cellulose. Phetoho ena e ntlafatsa ho qhibiliha ha eona ha metsi 'me e fana ka litšobotsi tse phahameng tsa viscosity, e etsa hore e tšoanelehe bakeng sa lisebelisoa tse fapaneng indastering ea oli le khase, haholo-holo ts'ebetsong ea ho cheka.

Thepa ea Sodium Carboxymethyl Cellulose High Viscosity (CMC-HV):

1. Sebopeho sa Lik'hemik'hale: CMC-HV e entsoe ka ho arabela selulose ka sodium chloroacetate tlas'a maemo a alkaline, e leng se hlahisang ho kenngoa ha lihlopha tsa carboxymethyl mokokotlong oa cellulose.
2. Ho qhibiliha ha Metsi: Joalo ka PAC-R, CMC-HV e qhibiliha haholo ke metsi, e lumellang ho kenyeletsoa ha bonolo marong a ho cheka.
3. Ntlafatso ea Viscosity: CMC-HV e sebelisoa haholo-holo joalo ka viscosifier marong a chekang. E fana ka viscosity e phahameng ho mokelikeli, e thusa ho emisa le ho tsamaisa li-cutlets tsa drill.
4. Taolo ea Tahlehelo ea Mokelikeli: Ho tšoana le PAC-R, CMC-HV e boetse e thusa ho laola tahlehelo ea mokelikeli ka ho etsa kuku e sefang maboteng a seliba, ho thibela tlhaselo ea mokelikeli sebopehong.
5. Thermal Stability: CMC-HV e bonts'a botsitso bo botle ba mocheso, e etsa hore e loketse ho sebelisoa libakeng tsa ho cheka tse nang le mocheso o phahameng.
6. Mamello ea Letsoai: Le hoja e sa mamelle letsoai le phahameng joaloka PAC-R, CMC-HV e ntse e ka sebetsa ka katleho maemong a itekanetseng a letsoai.

Tšebeliso ea CMC-HV ho Mekelikeli ea ho Cheka:

1. Viscosifier: CMC-HV e eketsa viscosity ea maro a chekang, e thusang ho hloekisoa ha mekoti, ho emisoa ha lintho tse tiileng, le ho sebetsa hantle ha haeteroliki.
2. Setsi sa Tahlehelo ea Mekelikeli: E thusa ho theha kuku e tšesaane, e ke keng ea qoelisoa maboteng a seliba, e fokotsa tahlehelo ea mokelikeli sebopehong le ho fokotsa tšenyo ea sebopeho.
3. Thibelo ea Shale: CMC-HV e ka thibela ho phalla ha shale le ho hasana, ho thusa ho tsitsisa libopeho le ho thibela mathata a ho se tsitse ha wellbore.
4. Friction Reducer: Ntle le ntlafatso ea viscosity, CMC-HV e ka sebetsa joalo ka mokhoa oa ho fokotsa likhohlano, ho ntlafatsa ts'ebetso ea ts'ebetso ea ho cheka.

Mokhoa oa Tlhahiso oa CMC-HV:

Tlhahiso ea CMC-HV e kenyelletsa mehato e mengata:

1. Cellulose Sourcing: Cellulose, eo hangata e nkiloeng ho makhasi a lehong kapa lithareng tsa k'hothone, e sebetsa e le thepa e tala bakeng sa tlhahiso ea CMC-HV.
2. Etherification: Cellulose e kena etherification le sodium chloroacetate tlas'a maemo a alkaline ho hlahisa lihlopha tsa carboxymethyl mokokotlong oa cellulose.
3. Neutralization: Ka mor'a karabelo, sehlahisoa ha se nke lehlakore ho se fetolela ka mokhoa oa letsoai oa sodium, e leng ho ntlafatsang ho qhibiliha ha metsi.
4. Tlhoekiso: CMC-HV e kopaneng e ea hloekisoa ho tlosa litšila le ho netefatsa boleng ba sehlahisoa.
5. Ho omisa le ho Pakaletsa: CMC-HV e hloekisitsoeng e omisitsoe ebe e pakeloa hore e abeloe basebelisi ba ho qetela.

Tšusumetso ea Tikoloho:

1. Biodegradability: CMC-HV, e nkiloeng ho selulose, e ka senyeha tlas'a maemo a nepahetseng, e fokotsa tšusumetso ea eona ea tikoloho ha e bapisoa le lipolymer tsa maiketsetso.
2. Taolo ea Litšila: Ho lahloa ka nepo ha maro a cheka a nang le CMC-HV ho bohlokoa ho fokotsa tšilafalo ea tikoloho. Ho sebelisoa hape le kalafo ea maro a chekang ho ka thusa ho fokotsa likotsi tsa tikoloho.
3. Moshoelella: Boiteko ba ho ntlafatsa ts'ebetso ea tlhahiso ea CMC-HV e 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 CMC-HV 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 CMC-HV ka ts'ebeliso ea lisebelisoa tse ka nchafatsoang le lits'ebetso tsa tlhahiso ea 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 CMC-HV ts'ebetsong ea ho cheka.

Ka kakaretso, sodium carboxymethyl cellulose high viscosity (CMC-HV) ke tlatsetso ea bohlokoa marong a ho cheka, e sebetsang e le viscosifier, sesebelisoa sa taolo ea tahlehelo ea mokelikeli, le inhibitor ea shale. Thepa ea eona, ho kenyelletsa ho qhibiliha ha metsi, viscosity e phahameng, 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, liteko tse tsoelang pele tsa lipatlisiso le nts'etsopele li ikemiselitse ho ntlafatsa ts'ebetso le ts'ebetso ea tikoloho ea CMC-HV, ho netefatsa bohlokoa ba eona bo tsoelang pele mesebetsing ea ho cheka.
