1. Isingeniso
IHydroxyethyl Cellulose (HEC) iyi-polymer engeyona i-ionic emanzini encibilikayo ekhiqizwa ukusabela kwe-cellulose yemvelo kanye ne-ethylene oxide. Ngenxa yezakhiwo zayo eziyingqayizivele zomzimba namakhemikhali, njengokuncibilika kwamanzi okuhle, ukuqina, ukwenza ifilimu, ukuzinza kanye nekhono lokumiswa, i-HEC isetshenziswe kabanzi embonini yamakhemikhali.
2. Izinkambu Zokusebenza
2.1 Imboni yokuhlanganisa
Embonini yokumboza, i-HEC isetshenziswa kakhulu njenge-thickener ne-rheology modifier. Imisebenzi yayo ihlanganisa:
Ukuthuthukisa ukungaguquguquki kanye ne-rheology ye-coating: I-HEC ingakwazi ukulawula ngokuphumelelayo ukuziphatha kwe-rheological ye-coating, ithuthukise ukusebenza kokwakhiwa, yenza ukugqoka kungabi namathuba okucwila, futhi kube lula ukuxubha nokugoqa.
Ukuthuthukisa ukuzinza kwe-coating: I-HEC ine-solubility enhle kakhulu yamanzi kanye nokuvikelwa kwe-colloidal, okungavimbela ngokuphumelelayo ukuchithwa kwe-pigment kanye ne-stratification ye-coating, futhi kuthuthukise ukuzinza kwesitoreji sokugqoka.
Thuthukisa izakhiwo zefilimu zokumboza: I-HEC ingakha ifilimu efanayo ngesikhathi sokumisa inqubo yokugqoka, ukuthuthukisa amandla okumboza kanye ne-gloss yokugqoka.
2.2 Imboni kawoyela
Enqubweni yokumba uwoyela nokukhiqizwa kukawoyela, i-HEC isetshenziswa kakhulu njengesengezo sokumba uketshezi kanye noketshezi oluqhekekayo. Imisebenzi yayo ihlanganisa:
Ukuqina nokumiswa: I-HEC ingakhuphula ngokuphawulekayo i-viscosity yoketshezi lokumba kanye noketshezi oluphukayo, imise ngokuphumelelayo ukusika ama-drill cuttings nama-propants, ivimbele ukuwa kwe-wellbore futhi ikhulise ukukhiqizwa komthombo kawoyela.
Ukulawulwa kokuhlunga: I-HEC ingalawula ngempumelelo ukulahlekelwa kokuhlunga koketshezi lokumba, inciphise ukungcoliswa kokwakheka, futhi ithuthukise ukuzinza nokukhiqiza umthamo wemithombo kawoyela.
Ukuguqulwa kwe-Rheological: I-HEC ingathuthukisa i-rheology yoketshezi lokumba kanye noketshezi oluphukayo, ithuthukise umthamo wayo wokuthwala isihlabathi, futhi ithuthukise ukusebenza kahle kanye nomthelela wokusebenza kokuqhekeka.
2.3 Imboni yezokwakha
Embonini yezokwakha, i-HEC ivame ukusetshenziswa odakeni lukasimende, imikhiqizo ye-gypsum nopende we-latex. Imisebenzi yayo eyinhloko ihlanganisa:
Ukuqina nokugcinwa kwamanzi: I-HEC ingathuthukisa ukuhambisana kwe-mortar ne-gypsum, ikhulise ukusebenza ngesikhathi sokwakha, futhi ithuthukise ukugcinwa kwayo kwamanzi, ivimbele ukulahlekelwa kwamanzi, futhi ithuthukise amandla okubopha.
I-Anti-sagging: Kupende we-latex, i-HEC ingavimbela upende ukuthi ungagxumeki endaweni eqondile, igcine umfaniswano wokumboza, futhi ithuthukise ikhwalithi yokwakha.
Ukubopha okuthuthukisiwe: I-HEC ingathuthukisa ukuhlangana phakathi kodaka lukasimende ne-substrate, ikhulise amandla nokuqina kwempahla.
2.4 Imboni Yamakhemikhali Yansuku zonke
Ukusetshenziswa okuyinhloko kwe-HEC emikhiqizweni yamakhemikhali yansuku zonke kuhlanganisa ukusetshenziswa njengesithako esijiyayo, isinzisi kanye nesigaxamisi sezinto zokuhlanza, ama-shampoos, okokugcoba nezimonyo. Imisebenzi yayo ihlanganisa:
Ukuqina: I-HEC ingakhuphula kakhulu i-viscosity yemikhiqizo yamakhemikhali yansuku zonke, yenze ukuthungwa komkhiqizo kube ntekenteke futhi kube kuhle ukukusebenzisa.
Ukuzinzisa: I-HEC inokunyibilika okuhle kwamanzi kanye nokuvikelwa kwe-colloid, ingakwazi ukuzinzisa uhlelo lwe-emulsified, ivimbele ukuhlukaniswa kwamanzi kawoyela, futhi yandise impilo yeshalofu yomkhiqizo.
Ukumiswa: I-HEC ingamisa izinhlayiya ezinhle, ithuthukise ukuhlakazeka nokufana komkhiqizo, futhi ithuthukise ukubukeka nokuthungwa.
2.5 Imboni Yezemithi
Embonini yezemithi, i-HEC isetshenziswa kakhulu njenge-binder kanye ne-ejenti ekhishwa njalo, i-ejenti ye-gelling kanye ne-emulsifier yamaphilisi. Imisebenzi yayo ihlanganisa:
Ukubopha: I-HEC ingabopha ngempumelelo izinhlayiya zezidakamizwa futhi ithuthukise amandla emishini nokusebenza kokuhlakazeka kwamaphilisi.
Ukukhululwa okusimeme: I-HEC ingalungisa izinga lokukhululwa kwezidakamizwa, izuze imiphumela eqhubekayo noma elawulwayo yokukhululwa, futhi ithuthukise ukusebenza kwezidakamizwa nokuthobela isiguli.
I-Gel kanye ne-emulsification: I-HEC ingenza i-gel iyunifomu noma i-emulsion ekwakhiweni kwezidakamizwa, ithuthukise ukuzinza nokunambitheka komuthi.
3. Izinzuzo nezici
3.1 Ukuqina okuhle kakhulu kanye nezimpawu ze-rheological
I-HEC inekhono elihle kakhulu lokujiya kanye nokuguqulwa kwe-rheological, okungakhuphula ngokuphawulekayo i-viscosity yezixazululo ezinamanzi, kuzenze ziziphathe njengama-pseudoplastic fluids ngamanani aphansi okugunda kanye noketshezi lwe-Newtonian emazingeni aphezulu e-shear. Lokhu kuyenza ikwazi ukuhlangabezana nezidingo ze-rheological zezinhlobonhlobo zezicelo zezimboni.
3.2 Ukuzinza nokuhambisana
I-HEC inokuqina okuhle kwamakhemikhali, ingakwazi ukugcina ukusebenza okuzinzile phezu kwebanga elibanzi le-pH, futhi iyahambisana nezinhlobonhlobo zamakhemikhali nezincibilikisi. Lokhu kuyenza ikwazi ukugcina umphumela wokujiya nokuzinzisa ezinzile ezinhlelweni zamakhemikhali eziyinkimbinkimbi.
3.3 Ukuvikelwa kwemvelo kanye nokuphepha
I-HEC yenziwe nge-cellulose yemvelo, inokubola okuhle kwe-biodegradability futhi inobungani nemvelo. Ngesikhathi esifanayo, i-HEC ayinabo ubuthi futhi ayinabungozi, futhi ilungele imikhiqizo yansuku zonke yamakhemikhali nemithi enezidingo zokuphepha eziphezulu.
I-Hydroxyethyl cellulose (HEC) inohlu olubanzi lwezinhlelo zokusebenza futhi idlala indima ebalulekile embonini yamakhemikhali. Ukuqina kwayo okuhle kakhulu, izakhiwo ze-rheological, ukuzinza nokuhambisana kwenza kube isengezo esibalulekile ezimbonini eziningi ezifana nezingubo, i-petroleum, ukwakhiwa, amakhemikhali nsuku zonke kanye nemithi. Ngokuthuthuka kobuchwepheshe kanye nezinguquko ezidingekayo zemakethe, amathuba okufaka isicelo e-HEC azoba banzi.
