Selulose ea Hydroxyethyl ka Mokelikeli oa ho Cheka

Hydroxyethyl cellulose (HEC) ke polima e qhibilihang ka metsing eo hangata e sebelisoang e le viscosifier ha ho cheka maro. Mokelikeli oa ho cheka, oo hape o tsejoang e le seretse sa ho cheka, ke karolo ea bohlokoa ts'ebetsong ea ho cheka e sebelisoang ho phenyekolla oli le khase, tlhahiso ea matla a mocheso oa mocheso oa mocheso le ho ntšoa ha liminerale. Sehloohong sena, re tla tšohla mefuta e fapaneng ea ts'ebeliso ea HEC ho maro a ho cheka.

Taolo ea Viscosity

E 'ngoe ea likopo tse ka sehloohong tsa HEC ho maro a ho cheka ke ho laola viscosity ea mokelikeli. Viscosity e bolela botenya kapa ho hana ho phalla ha mokelikeli. Ts'ebetso ea ho phunya e hloka mokelikeli o ka phallang habonolo ka har'a setsi sa ho phunya ebe o tsamaisa li-cuttings tsa ho phunya holimo. Leha ho le joalo, haeba viscosity ea mokelikeli o le tlase haholo, e ke ke ea khona ho jara li-cuttings, 'me haeba e phahame haholo, ho tla ba thata ho pompa ka har'a seliba.

HEC ke viscosifier e sebetsang hantle hobane e ka eketsa viscosity ea mokelikeli oa ho cheka ntle le ho eketsa bongata haholo. Sena se bohlokoa hobane mokelikeli o matla haholo o ka baka tšenyo selibeng 'me o ka ba oa etsa hore seliba se putlame. Ho feta moo, HEC e sebetsa maemong a tlase, e leng ho thusang ho fokotsa litšenyehelo tse akaretsang tsa mokelikeli oa ho cheka.

Tahlehelo ea Mokelikeli

Tšebeliso e 'ngoe ea bohlokoa ea HEC ho maro a ho cheka ke taolo ea tahlehelo ea mokelikeli. Ho lahleheloa ke metsi ho bolela ho lahleheloa ke mokelikeli ka har'a sebopeho nakong ea ho cheka. Sena se ka baka phokotso ea molumo oa mokelikeli oa ho cheka, e leng se ka bakang botsitso bo bobe ba seliba le ho fokotsa bokhoni ba ho cheka.

HEC ke sesebelisoa se sebetsang sa ho laola tahlehelo ea mokelikeli hobane se ka etsa kuku e tšesaane, e ke keng ea qojoa holim'a sebopeho. Keke ena ea sesefa e thusa ho thibela mokelikeli oa ho cheka hore o se ke oa kenella ka har'a sebopeho, ho fokotsa tahlehelo ea mokelikeli le ho boloka botsitso ba hantle.

Ho Emisa le Bokhoni ba ho Jara

HEC e boetse e sebelisoa ho cheka maro e le ho emisa le ho jara. Ts'ebetso ea ho cheka e kenyelletsa tšebeliso ea mefuta e fapaneng ea li-additives tse tiileng, ho kenyelletsa le barite le lisebelisoa tse ling tsa boima, tse kenyelletsoang mokelikeli ho eketsa bongata ba eona. HEC e sebetsa ka katleho ho emiseng li-additives tsena tse tiileng ka har'a mokelikeli le ho li thibela ho lula tlase ho seliba.

Ho feta moo, HEC e ka eketsa matla a ho jara a mokelikeli oa ho cheka. Sena se bolela palo ea likheo tsa ho cheka tseo mokelikeli o ka li tsamaisang holimo. Mokelikeli o nang le bokhoni bo phahameng ba ho jara o ka thusa ho ntlafatsa bokhoni ba ho cheka le ho fokotsa kotsi ea ho se tsitse ha liliba.

Mocheso le pH Botsitso

Mekelikeli ea ho cheka a tlas'a maemo a fapaneng a tikoloho, ho kenyelletsa le mocheso o phahameng le maemo a acidic. HEC e khona ho boloka li-viscosity le botsitso maemong ana a feteletseng, e leng se etsang hore e be tlatsetso e sebetsang bakeng sa maro a ho cheka a sebelisoang libakeng tse thata.

HEC e boetse e na le pH e tsitsitseng, ho bolelang hore e ka boloka viscosity ea eona le lisebelisoa tse ling ka metsi a nang le mefuta e mengata ea pH ea boleng. Sena se bohlokoa hobane pH ea maro a ho cheka a ka fapana haholo ho latela maemo a jeoloji a seliba.

Qetello

HEC ke tlatsetso ea bohlokoa ea maro a ho cheka ka lebaka la bokhoni ba eona ba ho laola viscosity, ho fokotsa tahlehelo ea mokelikeli, ho emisa le ho jara li-additives tse tiileng, le ho boloka botsitso libakeng tse thata.
