1. Isingeniso
I-Hydroxyethyl Cellulose (HEC) iyinto ye-polymer engeyona i-ionic encibilikayo emanzini ekhiqizwa ukusabela kwe-cellulose yemvelo kanye ne-ethylene oxide. Ngenxa yezakhiwo zayo eziyingqayizivele zomzimba nezamakhemikhali, njengokuncibilika kwamanzi okuhle, ukuqina, ukwakha ifilimu, ukuzinza kanye nekhono lokumiswa, i-HEC isetshenziswe kabanzi embonini yamakhemikhali.
2. Izinkambu Zohlelo Lokusebenza
2.1 Imboni Yokumboza
Embonini yokumboza, i-HEC isetshenziswa kakhulu njengesithambisi sokujiya kanye nesiguquli se-rheology. Imisebenzi yayo ifaka:
Ukuthuthukisa ukuhambisana kanye nokwakheka kwengubo: I-HEC ingalawula ngempumelelo ukuziphatha kwengubo kwengubo, ithuthukise ukusebenza kokwakhiwa, yenze ingubo ingabi lula ukugoba, futhi kube lula ukuyixubha nokuyigoqa.
Ukuthuthukisa ukuzinza kwengubo: I-HEC inokuncibilika kwamanzi okuhle kakhulu kanye nokuvikelwa kwe-colloidal, okungavimbela ngempumelelo ukuthungwa kwe-pigment kanye nokuhlukaniswa kwengubo, futhi kuthuthukise ukuzinza kwengubo yokugcina.
Thuthukisa izakhiwo zokwakha ifilimu zezimbozo: I-HEC ingakha ifilimu efanayo ngesikhathi senqubo yokomisa isimbozo, ithuthukise amandla okumboza kanye nokucwebezela kwesimbozo.
2.2 Imboni kaphethiloli
Enkambisweni yokubhoboza uwoyela nokukhiqizwa kwawoyela, i-HEC isetshenziswa kakhulu njengesithasiselo soketshezi lokubhoboza kanye noketshezi lokuqhekeka. Imisebenzi yayo ihlanganisa:
Ukuqina nokumiswa: I-HEC ingakhulisa kakhulu ukujiya koketshezi lokubhoboza kanye noketshezi lokuqhekeka, imise ngempumelelo izingcezu zokubhoboza kanye nama-proppants, ivimbele ukuwohloka kwe-wellbore futhi ikhulise ukukhiqizwa kwemithombo kawoyela.
Ukulawulwa kokuhlunga: I-HEC ingalawula ngempumelelo ukulahleka kokuhlunga koketshezi lokubhoboza, inciphise ukungcola kokwakheka, futhi ithuthukise ukuzinza kanye namandla okukhiqiza emithombo kawoyela.
Ukuguqulwa kwe-Rheological: I-HEC ingathuthukisa i-rheology yoketshezi lokubhoboza kanye noketshezi lokuqhekeka, ithuthukise amandla ayo okuthwala isihlabathi, futhi ithuthukise ukusebenza kahle kanye nomphumela wemisebenzi yokuqhekeka.
2.3 Imboni yokwakha
Embonini yokwakha, i-HEC ivame ukusetshenziswa ku-samente mortar, imikhiqizo ye-gypsum kanye nopende we-latex. Imisebenzi yayo eyinhloko ihlanganisa:
Ukuqina nokugcinwa kwamanzi: I-HEC ingathuthukisa ukuhambisana kwe-mortar ne-gypsum, yandise ukusebenza kahle ngesikhathi sokwakhiwa, futhi ithuthukise ukugcinwa kwamanzi kwayo, ivimbele ukulahleka kwamanzi, futhi ithuthukise amandla okubopha.
Ukungaguquguquki: Kupende we-latex, i-HEC ingavimbela upende ukuthi ungaguquguquki ezindaweni eziqondile, igcine ukumbozwa kufana, futhi ithuthukise ikhwalithi yokwakha.
Ukubopha okuthuthukisiwe: I-HEC ingathuthukisa ukubopha phakathi kodaka lukasimende kanye ne-substrate, yandise amandla nokuqina kwezinto.
2.4 Imboni Yamakhemikhali Yansuku Zonke
Ukusetshenziswa okuyinhloko kwe-HEC emikhiqizweni yamakhemikhali yansuku zonke kufaka phakathi ukusetshenziswa njengesithambisi, isiqinisi kanye nesithambisi sezinto zokuhlanza, ama-shampoo, ama-lotion kanye nezimonyo. Imisebenzi yayo ifaka:
Ukuqina: I-HEC ingakhulisa kakhulu ukujiya kwemikhiqizo yamakhemikhali yansuku zonke, okwenza ukuthungwa komkhiqizo kube bucayi futhi kube kuhle ukukusebenzisa.
Ukuzinza: I-HEC inokuncibilika kwamanzi okuhle kanye nokuvikelwa kwe-colloid, ingazinzisa uhlelo oluhlanganisiwe, ivimbele ukuhlukaniswa kwamafutha namanzi, futhi yandise impilo yeshelufu yomkhiqizo.
Ukumiswa: I-HEC ingamisa izinhlayiya ezincane, ithuthukise ukuhlakazeka kanye nokufana komkhiqizo, futhi ithuthukise ukubukeka kanye nokuthungwa.
2.5 Imboni Yezemithi
Embonini yezemithi, i-HEC isetshenziswa kakhulu njenge-binder kanye ne-ejenti yokukhulula okuqhubekayo, i-gelling agent kanye ne-emulsifier yamaphilisi. Imisebenzi yayo ihlanganisa:
Ukubopha: I-HEC ingabopha ngempumelelo izinhlayiya zemithi futhi ithuthukise amandla okusebenza kanye nokusebenza kokuqhekeka kwamaphilisi.
Ukukhishwa okuqhubekayo: I-HEC ingalungisa izinga lokukhishwa kwemithi, ifinyelele imiphumela yokukhishwa okuqhubekayo noma okulawulwayo, futhi ithuthukise ukusebenza kahle kwemithi kanye nokuthobela imithetho yesiguli.
Ijeli kanye ne-emulsification: I-HEC ingakha ijeli noma i-emulsion efanayo ekwakhiweni kwesidakamizwa, ithuthukise ukuzinza kanye nokunambitheka kwesidakamizwa.
3. Izinzuzo nezici
3.1 Izakhiwo ezinhle kakhulu zokujiya kanye ne-rheological
I-HEC inekhono elihle kakhulu lokuqinisa nokuguqula i-rheological, elingakhulisa kakhulu i-viscosity yezixazululo zamanzi, okwenza zisebenze njengoketshezi lwe-pseudoplastic ngesilinganiso esiphansi sokusika kanye noketshezi lwe-Newtonian ngesilinganiso esiphakeme sokusika. Lokhu kwenza ikwazi ukuhlangabezana nezidingo ze-rheological zezicelo ezahlukahlukene zezimboni.
3.2 Ukuqina nokuhambisana
I-HEC inamandla amahle okuqina kwamakhemikhali, ingagcina ukusebenza okuzinzile ebangeni elibanzi le-pH, futhi iyahambisana namakhemikhali ahlukahlukene kanye nezinyibilikisi. Lokhu kuyenza ikwazi ukugcina ukuqina okuzinzile kanye nomphumela wokuzinza ezinhlelweni zamakhemikhali eziyinkimbinkimbi.
3.3 Ukuvikelwa nokuphepha kwemvelo
I-HEC yenziwe nge-cellulose yemvelo, inokubola okuhle futhi inobungani nemvelo. Ngesikhathi esifanayo, i-HEC ayinabo ubuthi futhi ayinangozi, futhi ifaneleka emikhiqizweni yansuku zonke yamakhemikhali neyemithi enezidingo zokuphepha eziphezulu.
I-Hydroxyethyl cellulose (HEC) inezinhlobo eziningi zezicelo futhi idlala indima ebalulekile embonini yamakhemikhali. Ukuqina kwayo okuhle kakhulu, izakhiwo ze-rheological, ukuzinza kanye nokuhambisana kwayo kwenza kube yinto ebalulekile ezimbonini eziningi ezifana nokugqoka, uphethiloli, ukwakhiwa, amakhemikhali ansuku zonke kanye nemithi. Ngokuthuthuka kobuchwepheshe kanye nezinguquko ekudingweni kwemakethe, amathuba okusetshenziswa kwe-HEC azoba maningi.
