Izakhiwo kanye nokusebenzisa kwe-hydroxyethyl celtulose (HEC)

1. Izakhiwo ze-hydroxyethyl cellulose
I-Hydroxyyethyl cellulose (I-HEC, i-Hydroxyyethyl celtuleose) iyingxenye yamanzi ebekiwe i-polymer etholwe ukuguqulwa kwamakhemikhali kwe-cellulose yemvelo. Isakhiwo saso sakhiwa ama-glucose amayunithi axhunywe ngamabhondi angu-β-1,4-glycosidic. Amaqembu e-HydroxyEthyl (-ch2chCH2OH) angeniswa kumamolekyuli we-Hydroxyethyl cellulose, okuhlanganisa namaqembu we-hydroxy e-cellulose ngokusebenzisa ukusabela kwamakhemikhali. Ngenxa yalokhu kuguqulwa, i-HEC inezakhiwo eziningi ezihlukile kusuka ku-cellulose yangempela.

Izakhiwo Ezibonakalayo
Ukubukeka: I-HEC imvamisa i-amorphous powder emhlophe noma emhlophe emhlophe enobuhlakani obuhle.
I-Solubinity: I-HEC incibilika kalula emanzini, ikakhulukazi emanzini abandayo, akha isixazululo se-viscous. Lokhu kungenxa yokuhlanganiswa kwe-hydrogen phakathi kweHydroxyethyl Group kanye nama-molecule amanzi, anika amandla i-hec ukuthi ihlakazeke kakhulu emanzini.
I-Viscosity: Isixazululo se-HEC emanzini sibonisa ukubonakala okuphezulu, futhi ukubonakala kuhlobene kakhulu nesisindo se-molecular kanye nokuhlushwa kwesixazululo. Ngokuvamile, i-viscosity ye-HEC inyuka ngokwanda kwesisindo se-molecular.
Ukuqina okushisayo: I-HEC inokuqina okuhle okushisayo futhi ingakwazi ukugcina ukusebenza okuzinzile ngaphakathi kobubanzi bokushisa obuthile. Ngokuvamile, i-HEC ingamelana namazinga okushisa aphezulu, kepha ukusebenza kwayo kuyokwehla ngemuva kokushisa okungamazinga athile.

Izakhiwo Zamakhemikhali
Umsebenzi ongaphezulu: Iqembu le-hydroxyethyl ku-hec molecule yi-hydrophilic, evumela i-hec ukwakha isisombululo esizinzile emanzini futhi ithuthukise umsebenzi wendawo.
Ukuguqulwa: Ngokushintsha izimo zokuphendula ekuphenduleni kwamakhemikhali, isisindo se-molecular, i-solubity, ukubonana nezinye izakhiwo zika-HEC zingashintshwa ukuze zihlangabezane nezidingo ezihlukile zokusebenzisa.
Ukuqina kwe-PH: I-HEC iqinile emvelweni engathathi hlangothi noma ebuthakathaka, kepha i-solubeni yayo ingathinteka ezingeni elithile ngaphansi kwezimo eziqinile ze-acidic noma ze-alkali.

2. Ukusetshenziswa kwe-hydroxyethyl cellulose
Ngenxa yezakhiwo zayo ezinhle kakhulu, i-HEC isetshenziswe kabanzi emikhakheni ehlukahlukene. Ukusetshenziswa okuyinhloko kufaka phakathi izici ezilandelayo:

Imboni yezokwakha embonini yezokwakha, i-HEC ivame ukusetshenziswa njengesengezo sezinto zokwakha, ikakhulukazi ku usimende, i-gypsum, ukumboza, ukunamathela kweminye imikhiqizo. I-HEC ingathuthukisa ukuvumelana, ubisi kanye nokusebenza kwalezi zinto zokwenziwa. Ngaphezu kwalokho, i-HEC ingathuthukisa nokugcinwa kwamanzi kodaka, yandisa isikhathi sokwakha, futhi ivikele usimende ekuhleleni ngokushesha okukhulu. Ngenxa yezakhiwo zayo zokuqina, i-HEC ingathuthukisa ukumbozwa kanye nokunamathelisa kwezingubo zokwakha.

Imboni yamakhemikhali yansuku zonke embonini yamakhemikhali yansuku zonke, i-HEC isetshenziswa kabanzi ekukhiqizweni kwezinsimbi, ama-shampoos, ama-gels okugeza, okhilimu neminye imikhiqizo. Iqhaza eliphambili le-HEC kule mikhiqizo linjengesikhumuleli, ukumisa i-ejenti, i-emulsifier ne-stabilizer. I-HEC ingasiza imikhiqizo ukuba ilondoloze i-viscosity efanelekile, inikeze umuzwa omuhle wokusebenzisa, futhi uthuthukise ukuqina komkhiqizo. Ngaphezu kwalokho, i-HEC ingathuthukisa futhi izakhiwo ze-bhe ngokomqondo zokuhlanza ukuqinisekisa ukufana kwabo kanye nokusebenza ngempumelelo ngesikhathi sokusetshenziswa.

Imboni yokudla i-HEC isetshenziswa njengesikhudlwana, i-stabilizer kanye ne-emulsifier embonini yokudla, ikakhulukazi ekudleni okufana no-ayisikhilimu, ujusi, izinkokhelo kanye nokugqoka kwesaladi. Ngoba i-HEC ine-solubility yamanzi amahle, ingathuthukisa ukunambitheka kanye nokuthungwa kokudla, yandise ukuvumelana kwemikhiqizo, ithuthukise ukulimala kokudla, futhi yandise impilo eshalofini.

Imboni yezemithi embonini yezemithi, i-HEC isetshenziswa ikakhulukazi njengenkampani yenethiwekhi, i-emulsifier, enamathela futhi ikhudlwana izidakamizwa. Kusetshenziselwa ukulungiselela izidakamizwa zomlomo, ama-opels aphezulu, ama-gels, amaconsi wamehlo, njll. Amalungiselelo wezidakamizwa, uqinisekise ukuqina kwezidakamizwa, aqinisekise ukuqina kwezidakamizwa, futhi athuthukise ukungatholakali kwezidakamizwa.

I-Agenct yezolimo isetshenziswa kabanzi kwezolimo njenge-ejenti yokuvikela izitshalo, i-pesticide emulsifier kanye nomanyolo omkhulu. Kungathuthukisa ukusabalalisa kwezibulala-zinambuzane, zisize ama-pesticides ukuthi afafazwe ngokulinganayo futhi athuthukise ukunamathela kwemithi yokubulala izinambuzane. Ngasikhathi sinye, i-HEC nayo ingathuthukisa ukuqina komanyolo, inciphise ukulahleka komanyolo enhlabathini, futhi uthuthukise ukusebenza kahle komanyolo.

I-Petroleum Industry Hec idlala indima ebalulekile embonini kaPetroleum, ikakhulukazi ekuvuneni uketshezi kanye namakhemikhali we-oilfield. Isetshenziswa njengomuntu omkhulu, umenzi osomisayo ne-stabilizer. I-HEC ingakhuphula i-viscosity yokuvuza uketshezi futhi ithuthukise umthamo othwala uketshezi, ukuze ikwazi ukuthwala ngempumelelo imfucumfucu eyakhiwe ngesikhathi sokumba. Ngasikhathi sinye, i-HEC ingavimbela ukuvuza okuwuketshezi emafutheni namagesi ngesikhathi sokumba ukuze kuqinisekiswe inqubekela phambili yokusebenza ebushelelezi.

IHydroxYethyl Cellulose (I-HEC) iyisitatimende se-polymer esine-soluble polymer ngokusebenza okuhle kakhulu. Ukuqina kwayo okuyingqayizivele, ukuqina kwamanzi ane-soubelity enhle kwenza kusetshenziswe kabanzi ezimbonini eziningi ezinjengezokwakha, amakhemikhali nsuku, ukudla, umuthi, umuthi, ezolimo kanye nophethiloli. Ngokuthuthukiswa kwezobuchwepheshe, inqubo yokukhiqiza nokulawulwa kokusebenza kwe-HEC kuzoqhubeka nokuthuthuka, futhi amathemba awo okufaka isicelo azoba abanzi.
