Ukusetyenziswa kwe-Hydroxyethyl Cellulose (HEC)

I-Hydroxyethyl cellulose (HEC) yi-ether ye-cellulose engeyo-ionic eyenziwe kwi-cellulose yendalo ye-polymer yendalo ngoluhlu 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

ukutyabeka
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.

ulwakhiwo
Kwintsimi yoshishino lokwakha, i-HEC isetyenziswe njengesongezo kwizinto ezifana nezixhobo zodonga, ikhonkrithi (kubandakanywa ne-asphalt), iileyile eziqhotyoshelweyo kunye nezinto zokukhahlela.

Izongezo zinokwandisa i-viscosity kunye nokuqina kwezinto zokwakha, ukuphucula ukunamathela, ukuthambisa, kunye nokugcinwa kwamanzi, ukwandisa amandla okuguquguquka kwamalungu okanye amacandelo, ukuphucula ukucutheka, kunye nokuphepha ukuqhekeka komphetho.

Umqhaphu
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.

imichiza yemihla ngemihla
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.

ukwenza iphepha
Kwintsimi yokwenza iphepha, i-HEC ingasetyenziswa njenge-arhente yokulinganisa, i-arhente yokomeleza kunye nesilungisi sephepha.

ukomba ioli
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

ezolimo
I-Hydroxyethyl cellulose (HEC) inokunqumamisa ngokufanelekileyo iityhefu eziqinileyo kwizitshizi ezisekwe emanzini.

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; njengento yokuncamathelisa ekusetyenzisweni kwakhona kwamagqabi ecuba.

umlilo
Iselulosi yeHydroxyethyl ingasetyenziswa njengesongezelelo sokwandisa ukusebenza kokugquma kwezinto ezingatshiyo, kwaye isetyenziswe ngokubanzi ekulungiseleleni “izityebi” ezingatshiyo.

ukwenza
IHydroxyethylcellulose inokuphucula amandla amanzi kunye nokuncipha kwesanti yesamente kunye neenkqubo zesanti ye-sodium silicate.

Imicroscope
I-Hydroxyethyl cellulose ingasetyenziselwa ukuveliswa kweefilimu kunye ne-dispersant ekuveliseni izilayidi ezincinci.

I-Thickener kulwelo oluphezulu lwetyuwa olusetyenziselwa ukusetyenzwa kwefilimu.

ipeyinti ye-fluorescent tube
Isetyenziswe njenge-binder kunye ne-disperant ezinzileyo kwii-agent ze-fluorescent kwiingubo ze-fluorescent tube.

I-Electroplating kunye ne-Electrolysis
Inokukhusela i-colloid kwimpembelelo yoxinaniso lwe-electrolyte; I-hydroxyethyl cellulose inokukhuthaza ukubekwa okufanayo kwisisombululo se-cadmium plating.

iiseramikhi
Ingasetyenziselwa ukwenza izibophelelo eziphezulu zamandla kwiiseramikhi.

intambo
Izinto ezigxotha amanzi zithintela ukufuma ekungeneni kwiintambo ezonakalisiweyo.
