Iselulosi yeHydroxyethyl (HEC)yi-ether ye-cellulose engeyo-ionic eyenziwe kwi-cellulose yendalo ye-polymer yendalo ngothotho lwe-etherification. Ayinavumba, ingenancasa, i-powder emhlophe engenatyhefu okanye i-granule, enokuthi inyibilike emanzini abandayo ukwenza isisombululo se-viscous esicacileyo, kwaye ukuchithwa akuchaphazeli ixabiso le-pH. Inokuqina, ukubopha, ukusabalalisa, i-emulsifying, ifilimu-ifom, ukumisa, i-adsorbing, i-surface esebenzayo, igcina ukufuma kunye neempawu zetyuwa. Isetyenziswa kakhulu kwipeyinti, ukwakhiwa, i-textile, ikhemikhali yemihla ngemihla, iphepha, ukugaya ioli kunye namanye amashishini.
Iindawo ezisetyenziswayo eziphambili:
I-1.Ipeyinti: Ipeyinti esekwe ngamanzi ilulwelo lwe-viscous oluxutywe kunye ne-solvents eziphilayo okanye amanzi asekelwe kwi-resin, okanye i-oyile, okanye i-emulsion, kunye nokongezwa kwezongezo ezihambelanayo. Iingubo ezisekelwe emanzini ezinomsebenzi ogqwesileyo kufuneka zibe nokusebenza okugqwesileyo, amandla amahle okufihla, ukunamathela okuqinileyo, kunye nokusebenza kakuhle kokugcinwa kwamanzi; I-cellulose ether yeyona nto ifanelekileyo ekrwada ukubonelela ngezi mpawu.
2.Ulwakhiwo: Kwinkalo yoshishino lokwakha, iHEC isetyenziswa njengesongezo sezinto ezifana nodonga, ikhonkrithi (kubandakanywa ne-asphalt), iithayile ezincamathisiweyo kunye nezixhobo zokucoca, ezinokunyusa i-viscosity kunye nokujiya kwezinto zokwakha, ukuphucula ukunamathela, ukuthambisa, kunye nokugcinwa kwamanzi. Ukuphucula amandla e-flexural yamalungu okanye amacandelo, phucula i-shrinkage, kwaye ugweme ukuqhekeka komphetho.
I-3. I-Textile: I-HEC-ephathwe i-cotton, i-synthetic fibers okanye i-blends iphucula iimpawu zabo ezifana nokuxhathisa i-abrasion, ukudaya, ukuxhathisa umlilo kunye nokumelana ne-stain, kunye nokuphucula ukuzinza komzimba wabo (ukunciphisa) kunye nokuqina, ngakumbi kwiifayili zokwenziwa, okwenza ukuba ziphefumle kwaye zinciphise umbane omileyo.
4.Ikhemikhali yemihla ngemihla:I-Cellulose ether sisongezo esibalulekileyo kwiimveliso zemichiza yemihla ngemihla. Ayinakuphucula kuphela i-viscosity ye-liquid okanye i-emulsion cosmetics, kodwa iphucula ukusasazeka kunye nokuzinza kwe-foam.
Iphepha le-5.Iphepha: Kwinkalo yokwenza iphepha, i-HEC ingasetyenziswa njenge-ejenti yokulinganisa, i-arhente yokomeleza kunye nesilungisi sephepha.
I-6.I-Oil drilling: i-HEC isetyenziswa kakhulu njenge-ejenti yokuqina kunye nokuzinzisa kwinkqubo yonyango ye-oilfield. Yikhemikhali ye-oilfield elungileyo. Yayisetyenziswa kakhulu ekwembeni, ekugqityweni kakuhle, ekusamenteni kunye neminye imisebenzi yokuvelisa i-oyile kumazwe angaphandle ngeminyaka yoo-1960.
Eminye imimandla yesicelo:
I-HECinokudlala indima yokubambelela kwityhefu emagqabini kwimisebenzi yokutshiza; I-HEC ingasetyenziswa njenge-thickener ye-emulsions yokutshiza ukunciphisa ukukhukuliseka kwechiza, ngaloo ndlela yandisa isiphumo sokutshiza nge-foliar. I-HEC isenokusetyenziswa njenge-ejenti yokwenza ifilimu kwii-agent zokugquma imbewu; njengesibophelelo ekusetyenzisweni kwakhona kwamagqabi ecuba. I-cellulose ye-Hydroxyethyl ingasetyenziselwa njengesongezo sokwandisa ukusebenza kokugquma kwezinto ezingatshiyo, kwaye isetyenziswe ngokubanzi ekulungiseleleni "ii-thickeners" ezingenamlilo. I-Hydroxyethyl cellulose inokuphucula amandla amanzi kunye nokuncipha kwesanti yesamente kunye neenkqubo zesanti ye-sodium silicate. I-Hydroxyethyl cellulose ingasetyenziselwa ukuveliswa kweefilimu kunye ne-dispersant ekuveliseni izilayidi ezincinci. I-Thickener kulwelo olunetyuwa ephezulu esetyenziselwa ukusetyenzwa kwefilimu. Isetyenziswe njenge-binder kunye ne-disperant ezinzileyo kwii-agent ze-fluorescent kwiingubo ze-fluorescent tube. Inokukhusela i-colloid kwimpembelelo yoxinaniso lwe-electrolyte; I-hydroxyethyl cellulose inokukhuthaza ukubekwa okufanayo kwisisombululo se-cadmium plating. Ingasetyenziselwa ukwenza izibophelelo eziphezulu zamandla kwiiseramikhi. Izinto ezigxotha amanzi zithintela ukufuma ekungeneni kwiintambo ezonakalisiweyo.
