Hydroxyethylcellulose (HEC) ke thepa e feto-fetohang e sebelisoang haholo liindastering tse fapaneng ka lebaka la thepa ea eona e ikhethang. Lisebelisoa tsa eona li tloha ho li-detergents tsa pente le samente ho ea ho li-putty tsa lebota le lisebelisoa tse bolokang metsi. Tlhokahalo ea HEC e eketsehile lilemong tsa morao tjena mme ho lebelletsoe hore e tla tsoela pele ho hola le nakong e tlang.
HEC e tsoa ho cellulose, polymer ea tlhaho e fumanehang maboteng a lisele tsa semela. Lihlopha tsa Hydroxyethyl li kenngoa ka har'a ketane ea cellulose ka karabelo ea etherification, ka hona e fetola thepa ea eona. HEC e hlahisoang e ka qhibiliha ka har'a metsi le li-solvents tsa tlhaho, e leng se etsang hore e be khetho e ratoang bakeng sa mefuta e sa tšoaneng ea likopo.
E 'ngoe ea litšebeliso tse atileng haholo tsa HEC ke indastering ea ho roala. E sebetsa joalo ka motenya mme e fana ka viscosity ea pente, e etsa hore ho be bonolo ho e sebelisa. HEC e boetse e thusa ho thibela pente hore e se ke ea rotha kapa ea thella, e etsa bonnete ba hore e boreleli ebile e le holim'a metsi. Ho phaella moo, e ntlafatsa ho phalla ha pente, ho etsa hore ho be bonolo hore pente e khomarele bokaholimo bo pentiloeng. HEC e boetse e ntlafatsa ho hanyetsa ha pente ho metsi le abrasion, kahoo e matlafatsa nako e telele.
HEC e boetse e sebelisoa e le moemeli oa ho hloekisa indastering ea pente. E thusa ho tlosa litšila le litšila tse ling tse tsoang holim'a metsi a pentiloeng, e leng ho lumellang pente hore e be le sekhomaretsi se setle. E ka boela ea thusa ho thibela pente ho ebola kapa ho ebola ka ho ntlafatsa litšobotsi tsa eona tse tlamahanyang.
Tšebeliso e 'ngoe e kholo ea HEC ke indastering ea kaho. E sebelisoa haholo mefuteng ea samente le ea konkreite ka lebaka la bokhoni ba eona ba ho sebetsa e le ntho e teteaneng, e tsitsitseng le e bolokang metsi. E ntlafatsa ho sebetsa ha metsoako ea samente le konkreite, ho etsa hore ho be bonolo ho sebetsana le ho aha. HEC e boetse e thusa ho fokotsa palo ea metsi a hlokahalang motsoakong, e leng se etsang hore ho be le nako e telele ea nako e telele le matla.
Ho phaella ho samente le konkreite, HEC e boetse e sebelisoa ka libopeho tsa putty leboteng. E sebetsa e le motenya, e ntlafatsa thepa ea sekhomaretsi ea putty le ho etsa bonnete ba hore sebaka se boreleli, le lebota. HEC e boetse e thusa ho fokotsa palo ea shrinkage e hlahang nakong ea ts'ebetso ea ho omisa, kahoo e matlafatsa nako e telele ea putty.
HEC e boetse e sebelisoa e le sesebelisoa sa ho boloka metsi temong. E kenngoa mobung ho thusa ho boloka mongobo, e leng ntho ea bohlokoa bakeng sa kholo ea limela. HEC e thusa ho ntlafatsa sebopeho sa mobu, ho etsa hore ho be bonolo hore metso ea limela e kenelle le ho monya metsi le limatlafatsi.
Ka kakaretso, tšebeliso ea HEC e fetotse liindasteri tse fapaneng ka lebaka la thepa ea eona e ikhethang. E ntlafatsa boleng le ho tšoarella ha lipente, lisamente, li-putty tsa leboteng, le lisebelisoa tse bolokang metsi. Ke motsoako oa bohlokoa 'me o phetha karolo ea bohlokoa ho hlahisa lihlahisoa tsa boleng bo phahameng tse finyellang litlhoko tsa bareki.
E 'ngoe ea melemo ea mantlha ea HEC ke hore ha e na chefo ebile ha e na chefo. Ha e lematse tikoloho kapa hona ho beha likotsi leha e le life tsa bophelo ho batho kapa liphoofolo. Ho feta moo, e bonolo ho e tšoara le ho e tsamaisa, e etsa hore e be e loketseng lits'ebetso tse kholo tsa indasteri.
Bokamoso ba HEC bo khanya ’me ho lebeletsoe hore e tsoele pele ho phetha karolo ea bohlokoa liindastering tse fapa-fapaneng. Ha tlhoko ea lihlahisoa tsa boleng bo holimo e ntse e eketseha, tlhokahalo ea HEC le eona e tla eketseha, e tsamaise boqapi bo eketsehileng le nts'etsopele lefapheng lena.
Tšebeliso ea HEC e fetotse liindasteri tse fapaneng ka lebaka la thepa ea eona e ikhethang.
