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-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 zesicelo eziphambili:

1.Peyinta:Ipeyinti esekelwe ngamanzi 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 zokukhahlela, 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:I-HEC ephathwayo ikotoni, iifayili zokwenziwa okanye ukudibanisa ziphucula iipropati zabo ezifana nokuchasana kwe-abrasion, ukudaya, ukuxhathisa umlilo kunye nokuchasana kwebala, kunye nokuphucula ukuzinza komzimba wabo (ukunciphisa) kunye nokuqina, ngakumbi kwiifayili zokwenziwa, okwenza ukuba ziphefumule kwaye zinciphise 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 ezingatshiyo, kwaye isetyenziswe ngokubanzi ekulungiseleleni "ii-thickeners" ezingenamlilo. 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.
