Isetyenziselwa ntoni iHydroxyethyl Cellulose?

Iselulosi yeHydroxyethyl(HEC) yi-ether ye-cellulose engeyo-ionic eyenziwe kwi-cellulose yezinto ze-polymer yendalo ngokusebenzisa uchungechunge 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-ukwenza ifilimu, 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 zesicelo eziphambili:

1.Peyinta:Ipeyinti esekelwe emanzini i-viscous liquide eyenziwe nge-solvents eziphilayo okanye amanzi asekelwe kwi-resin, okanye ioli, 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.Cumyalelo:Kwinkalo yoshishino lokwakha, iHEC isetyenziswa njengesongezo sezinto ezinje ngodonga, ikhonkrithi (kubandakanywa ne-asphalt), iithayile ezincanyathisiweyo kunye nezixhobo zokucathula, ezinokunyusa i-viscosity kunye nokutyeba kwezinto zokwakha, ukuphucula ukunamathela, ukuthambisa, kunye namanzi. ugcino.Ukuphucula amandla e-flexural yamacandelo okanye amacandelo, phucula i-shrinkage, kwaye ugweme ukuqhekeka komphetho.

3.Texile:Ikotoni ephathwa nge-HEC, iifayili zokwenziwa okanye ukudibanisa ziphucula iipropathi zazo ezifana nokuchasana ne-abrasion, ukudaya, ukuchasana nomlilo kunye nokumelana nebala, kunye nokuphucula ukuzinza komzimba wabo (ukuncipha) kunye nokuqina, ngakumbi kwimicu yokwenziwa, eyenza ukuba iphefumle kwaye inciphise i-static. umbane.

4.Dikhemikhali ye-aily:I-ether ye-Cellulose iyongezwa ebalulekileyo kwiimveliso zemichiza yemihla ngemihla.Ayinakuphucula kuphela i-viscosity ye-liquid okanye i-emulsion cosmetics, kodwa iphucula ukusasazeka kunye nokuzinza kwe-foam.

5.Iphepha:Kwintsimi yokwenza iphepha, i-HEC ingasetyenziswa njenge-agent yokulinganisa, i-agent eyomeleza kunye ne-modifier yephepha.

6.Oukugrumba: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-HEC inokudlala 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 ngokutsha kwamagqabi ecuba.I-cellulose ye-Hydroxyethyl ingasetyenziselwa njengesongezo sokwandisa ukusebenza kokugquma kwezinto zomlilo, kwaye isetyenziswe ngokubanzi ekulungiseleleni "i-thickeners" yomlilo.I-Hydroxyethyl cellulose inokuphucula amandla amanzi kunye nokuncipha kwesanti yesamente kunye neenkqubo zesanti ye-sodium silicate.Iselulosi yeHydroxyethyl 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.
