I-Hydroxyethyl cellulose (HEC), i-polymer engeyona i-ionic, encibilikayo emanzini, inezinhlelo eziningi zokwakha izinhlelo zokubopha udonga lwangaphandle. Ngokuyinhloko ithuthukisa ukusebenza kahle kokubopha, ukugcinwa kwamanzi, izakhiwo zokulinganisa, kanye nekhwalithi yokwakha ifilimu, okwenza kube yinto ebalulekile ezinhlelweni zokubopha udonga lwangaphandle zanamuhla.
1.I-HEC inezindawo ezinhle kakhulu zokuncibilika kwamanzi kanye nokujiya, yakha isisombululo esizinzile ezinhlelweni zokumboza udonga lwangaphandle olusekelwe emanzini. Ngemva kokuncibilika, yandisa kakhulu ukujiya kodonga, ivimbele ukugoba, ukuconsa, noma ukwakheka ngesikhathi sokufaka, ngaleyo ndlela iqinisekise ukumboza okufanayo ebusweni bodonga. Ngesikhathi esifanayo, umphumela wokujiya we-HEC ulawula ngempumelelo izakhiwo ze-thixotropic zodonga, ugcina ukuqina okuthile lapho umile ngenkathi uvumela ukuthi kugeleze kalula ngesikhathi sokuxuba noma ukuxubha, okuthuthukisa ukusebenziseka kalula.
2.I-HEC ibonisa ukugcinwa kwamanzi okuhle kakhulu ezimbozweni zangaphandle zodonga. Ngesikhathi senqubo yokomisa, ukuhwamuka komswakama okusheshayo kakhulu kungaholela ekuncipheni kwefilimu, ukuqhekeka, noma ukuqhakaza, okuthinta ukumelana nesimo sezulu kanye nobuhle bengubo. I-HEC ingakhipha umswakama kancane kancane, yandise isikhathi sokuvula kwengubo futhi iholele ekwakhekeni kwefilimu efanayo futhi ebanzi, ithuthukise ukunamathela nokuqina ngemva kokomisa. Ngaphezu kwalokho, i-HEC ingasebenza ngokubambisana nezinye izithasiselo ezifana nezihlakaza kanye nama-eleveling agents ukuze kuthuthukiswe ukusebenza kwengubo kanye nokushelela kobuso.
3.Ezimbozweni zodonga zangaphandle, i-HEC ingathuthukisa nokuzinza kohlelo lokumboza. Izimbozo zodonga zangaphandle zivame ukuba yizinto eziqinile kakhulu, izinhlelo ezihlakazekile, ezithambekele ekuqhekekeni noma ekuhlukanisweni. Ezinhlelweni ezisekelwe emanzini, i-HEC ingakha isakhiwo senethiwekhi, imise futhi ihlakaze izinhlayiya ze-pigment kanye ne-filler, ivimbele ngempumelelo ukuqhekeka futhi iqinisekise ukuzinza kwesitoreji sesikhathi eside. Lokhu kubaluleke kakhulu ezimbozweni zodonga zangaphandle ezisetshenziswa ekwakheni okukhulu noma ekuthuthweni okude.
4.Inani le-HEC engeziwe kanye nesisindo sayo sama-molecule nakho kuyizinto ezibalulekile ekusetshenzisweni. Ngokuvamile, i-HEC ephezulu yesisindo sama-molecule inikeza imiphumela eqinile yokuqina kanye nokugcinwa kwamanzi, kuyilapho i-HEC yesisindo sama-molecule ephansi ifaneleka kakhulu ezinhlelweni zokumboza ezidinga ukugeleza okuphezulu kanye nokufuthwa. Umthamo we-HEC ezimbozweni zodonga zangaphandle uvame ukuba phakathi kuka-0.1% no-0.5%, olungiselelwe futhi ulungiswe ngokwezinhlobo ezahlukene zezinto eziyisisekelo, izindlela zokusetshenziswa, kanye nezimo zezulu. Ukwengezwa ngokweqile kwe-HEC kungaholela ekuqineni okukhulu kakhulu kokumboza, okuthinta ukusetshenziswa, kanti ukwengezwa okunganele kuzoyivimbela ekufezeni imisebenzi yayo yokugcina amanzi kanye nokulinganisa ehlosiwe.
5.I-HEC inezinzuzo futhi ekugqokeni odongeni lwangaphandle olunobungani nemvelo. Njenge-non-ionic natural polymer derivative, i-HEC inobuthi obuphansi futhi iyabola, ihlangabezana nezidingo zezingubo zesimanje zokwakha ze-VOC ephansi (ama-organic compounds aguquguqukayo) kanye nokusebenza kwemvelo. Ngaphezu kwalokho, ukusetshenziswa kwe-HEC akuvezi ukusabela okukhulu kwamakhemikhali ngama-pigment avamile, ama-filler, kanye nezithasiselo, ngaleyo ndlela kukhombisa ukuhambisana okuhle nokuzinza.
6.Ukusetshenziswa kweI-HECEzinhlelweni zokubopha udonga lwangaphandle kubonakala kakhulu ekuqineni, ukugcinwa kwamanzi, ukusebenza okuthuthukisiwe kohlelo, kanye nokuzinza kohlelo okuthuthukisiwe. Ukukhetha okufanele uhlobo lwe-HEC kanye nomthamo kungenza ngcono kakhulu ukusebenza kahle, ukumelana nesimo sezulu, kanye nokubukeka kokubopha, kunikeze ukwesekwa okuthembekile kocwaningo kanye nokusetshenziswa kokubopha udonga lwangaphandle okusebenzayo kakhulu. Njengoba izidingo ezikhulayo zokongiwa kwamandla okwakha kanye nokuvikelwa kwemvelo, ukusetshenziswa kwe-HEC kokubopha udonga lwangaphandle kuzosabalala kakhulu, futhi ukusebenza kwayo kanye nenani kuzoqhubeka nokuthuthukiswa nokuthuthukiswa.
