Yintoni iHydroxyethyl Cellulose?

I-Hydroxyethyl cellulose yi-fiber okanye i-powdery fibrous emhlophe ukuya kokhanyayo, eqinileyo okanye etyheli, ayinatyhefu, ayinancasa, kwaye inyibilika lula emanzini. Ayinyibiliki kwi-organic solvents. Ineempawu zokutyeba, ukuxhoma, ukubopha, ukuxuba, ukusasaza, kunye nokugcina umswakama. Izisombululo ezine-viscosity ezahlukeneyo zinokulungiswa. Inonyibiliko lwetyuwa oluhle kakhulu kwi-electrolytes. I-Hydroxyethyl cellulose yi-powder emhlophe okanye etyheli ekhanyayo engenavumba, engenancasa, kwaye elula ukuhamba. Iyanyibilika emanzini abandayo nashushu, kwaye ngokubanzi ayinyibiliki kwi-organic solvents ezininzi. I-viscosity ayitshintshi kangako xa ixabiso le-pH liphakathi kwe-2-12, kodwa i-viscosity iyancipha ngaphaya kolu luhlu.

Isicelo

1. I-Hydroxyethyl cellulose (HEC) yi-non-ionic soluble cellulose ether enokuqina okuhle, ukumiswa, ukusasazwa, i-emulsification, ukunamathela, ukwakheka kwefilimu, ukukhuselwa kokufuma kunye neempawu zokukhusela ze-colloid. Ngenxa yeempawu zayo ezizodwa zomzimba nezekhemikhali, i-HEC isetyenziswa kakhulu kwiindawo ezininzi, kubandakanya kodwa kungaphelelanga apho ekutsalweni kweoyile, ukugqunywa, ukwakhiwa, ukutya kwamayeza, amalaphu, ukwenza iphepha kunye ne-polymerization.
2. Kwicandelo lezamayeza, ukongeza ekubeni yinto etyebisayo nekhuselayo, i-hydroxyethyl cellulose ikwanefuthe lokufumisa, ukufumisa, ukulwa nokwaluphala, ukucoca ulusu, kunye nokususa i-melanin. Ifanelekile ukwenza amaconsi amehlo, izitshizi zeempumlo, izisombululo zomlomo, njl. Inganyusa i-viscosity yeyeza, iphucule izinga lokufunxwa kweyeza emzimbeni, kwaye yonyuse uzinzo lweyeza ukuthintela ukubola kweyeza kunye ne-oxidation.
3. Kwishishini lezinto zokuthambisa, i-HEC isetyenziswa kakhulu ekwenzeni ishampu, i-conditioner, i-cream, i-lotion kunye nezinye iimveliso. Ingalungisa ubungqingqwa kunye nobume bezinto zokuthambisa ukuze kube lula ukuzisebenzisa nokuzifunxa. Kwangaxeshanye, ikwanayo nefuthe lokufumisa, inokuvala ukufuma, kwaye ithintele ukoma nokuqhekeka kolusu.
4. Ukongeza, i-hydroxyethyl cellulose isetyenziswa kakhulu njengesithambisi-mbala, isithambisi-mbala kunye nesigcina-zimo kwishishini lokutya, nto leyo enokunyusa uburhabaxa kunye nobume bokutya kwaye iphucule incasa kunye nomgangatho wokutya. Ingasetyenziswa njenge-emulsifier kunye nesiqinisi ukuthintela ukwahlulwahlulwa kokutya kunye nokuna kwemvula.
5. Ngokuphathelele i-acidity kunye ne-alkalinity ye-hydroxyethyl cellulose, ekubeni ikwiklasi ye-non-ionic cellulose ether, ayina-acid kwaye ayina-alkaline. Ifomyula yayo yekhemikhali yi-(C2H6O2)n, ineempawu zokunyibilika ezilungileyo, uzinzo kunye nokuqina, kwaye idlala indima ebalulekileyo kwiindawo ezahlukeneyo zokusetyenziswa.
