Ts'ebetsong ea ho cheka oli le tlhahiso ea oli, HEC e sebelisoa haholo-holo e le tlatsetso bakeng sa mokelikeli oa ho cheka le mokelikeli oa fracturing.Mesebetsi ea eona e kenyelletsa:
Ho tenya le ho emisa: HEC e ka eketsa haholo viscosity ea mokelikeli oa ho cheka le mokelikeli oa fracturing, ea emisa ka nepo li-cuttings le li-proppants, ea thibela ho putlama ha liliba le ho eketsa tlhahiso ea seliba sa oli.
Taolo ea ho hloekisa: HEC e ka laola ka katleho tahlehelo ea ho hloekisa ea mokelikeli oa ho cheka, ho fokotsa tšilafalo ea sebopeho, le ho ntlafatsa botsitso le bokhoni ba tlhahiso ea liliba tsa oli.
Phetoho ea Rheological: HEC e ka ntlafatsa rheology ea mokelikeli oa ho cheka le mokelikeli o robehang, ho ntlafatsa bokhoni ba eona ba ho jara lehlabathe, le ho ntlafatsa ts'ebetso le phello ea ts'ebetso ea ho robeha.

2.3 Indasteri ea kaho
Lefapheng la kaho, HEC e atisa ho sebelisoa ka seretse sa samente, lihlahisoa tsa gypsum le pente ea latex.Mesebetsi ea eona ea mantlha e kenyelletsa:
Ho tiisa le ho boloka metsi: HEC e ka ntlafatsa ho tsitsisa ha seretse le gypsum, ho eketsa ts'ebetso nakong ea kaho, le ho ntlafatsa ho boloka metsi, ho thibela tahlehelo ea metsi, le ho ntlafatsa matla a ho kopanya.
Anti-sagging: Ka pente ea latex, HEC e ka thibela pente ho thella holim'a libaka tse otlolohileng, ho boloka seaparo sa seaparo, le ho ntlafatsa boleng ba kaho.
Khokahano e ntlafalitsoeng: HEC e ka ntlafatsa maqhama pakeng tsa seretse sa samente le substrate, ea eketsa matla le ho tšoarella ha thepa.

2.4 Indasteri ea Lik'hemik'hale ea Letsatsi le Letsatsi
Tšebeliso e ka sehloohong ea HEC lihlahisoa tsa letsatsi le letsatsi tsa lik'hemik'hale li kenyelletsa ho sebelisoa e le setenya, stabilizer le emulsifier bakeng sa sesepa, li-shampoo, litlolo le litlolo.Mesebetsi ea eona e kenyelletsa:
Ho teteana: HEC e ka eketsa viscosity ea lihlahisoa tsa letsatsi le letsatsi tsa lik'hemik'hale haholo, ea etsa hore sebopeho sa sehlahisoa se be bobebe 'me se be monate ho se sebelisa.
Ho tsitsa: HEC e na le ho qhibiliha ha metsi hantle le tšireletso ea colloid, e ka tsitsisa tsamaiso ea emulsified, e thibela ho arohana ha oli-metsi, le ho lelefatsa bophelo ba sethala sa sehlahisoa.
Ho emisoa: HEC e ka emisa likaroloana tse ntle, ea ntlafatsa ho hasana le ho tšoana ha sehlahisoa, le ho ntlafatsa ponahalo le sebopeho.

2.5 Indasteri ea Meriana
Indastering ea meriana, HEC e sebelisoa haholo-holo e le ntho e tlamang le e sa khaotseng ea tokollo, gelling agent le emulsifier bakeng sa matlapa.Mesebetsi ea eona e kenyelletsa:
Tlama: HEC e ka tlama likaroloana tsa lithethefatsi ka katleho le ho ntlafatsa matla a mochine le ts'ebetso ea ho arohana ha matlapa.
Tokollo e tsitsitseng: HEC e ka fetola tekanyo ea ho lokolloa ha lithethefatsi, ea finyella liphello tse tsitsitseng kapa tse laoloang, le ho ntlafatsa katleho ea lithethefatsi le ho latela mokuli.
Gel le emulsification: HEC e ka etsa gel e ts'oanang kapa emulsion ka mokhoa oa ho etsa lithethefatsi, ho ntlafatsa botsitso le tatso ea lithethefatsi.

3. Melemo le litšobotsi

3.1 Thepa e ntle haholo ea botenya le rheological
HEC e na le bokhoni bo babatsehang ba ho thibela le ho fetola li-rheological, tse ka eketsang haholo ponahalo ea litharollo tse nang le metsi a metsi, ho etsa hore li itšoare joaloka maro a pseudoplastic ka litekanyetso tse tlaase tsa ho kuta le metsi a Newtonian ka litekanyetso tse phahameng tsa ho kuta.Sena se e nolofalletsa ho fihlela litlhoko tsa rheological tsa mefuta e fapaneng ea likopo tsa indasteri.

3.2 Ho tsitsa le ho lumellana
HEC e na le botsitso bo botle ba lik'hemik'hale, e ka boloka ts'ebetso e tsitsitseng ho feta pH e pharaletseng, 'me e lumellana le mefuta e sa tšoaneng ea lik'hemik'hale le li-solvents.Sena se e nolofalletsa ho boloka phello e tsitsitseng ea ho teteana le ho tsitsisa lits'ebetsong tse rarahaneng tsa lik'hemik'hale.

3.3 Tšireletso le polokeho ea tikoloho
HEC e entsoe ka selulose ea tlhaho, e na le biodegradability e ntle ebile e baballa tikoloho.Ka nako e ts'oanang, HEC ha e na chefo ebile ha e na kotsi, 'me e loketse lihlahisoa tsa letsatsi le letsatsi tsa lik'hemik'hale le tsa meriana tse nang le litlhoko tse phahameng tsa tšireletso.

Hydroxyethyl cellulose (HEC) e na le mefuta e mengata ea lisebelisoa 'me e bapala karolo ea bohlokoa indastering ea lik'hemik'hale.Botenya ba eona bo babatsehang, thepa ea rheological, botsitso le ho lumellana ho etsa hore e be tlatsetso ea bohlokoa liindastering tse ngata tse kang liphahlo, petroleum, kaho, lik'hemik'hale tsa letsatsi le letsatsi le meriana.Ka nts'etsopele ea theknoloji le liphetoho tlhokahalong ea 'maraka, menyetla ea kopo ea HEC e tla ba e pharaletseng.
