Yintoni iHydroxyethyl Cellulose?

IHydroxyethyl cellulose yintsinga emhlophe ukuya kumthubi okhanyayo okanye umgubo oqinileyo, ongenatyhefu, awunancasa, kwaye unyibilika lula emanzini. Ayinyibiliki kwizinyibilikisi zendalo ngokubanzi. Ineempawu zokujiya, ukuxhoma, ukudibanisa, ukumilisela, ukusabalalisa, kunye nokugcina ukufuma. Izisombululo ezinoluhlu oluhlukeneyo lwe-viscosity zinokulungiswa. Inonyibiliko oluhle kakhulu lwetyuwa kwi-electrolytes. IHydroxyethyl cellulose ngumgubo omhlophe okanye okhanyayo ongenavumba, awunancasa, kwaye uqukuqela lula. Iyanyibilika kumanzi abandayo nashushu, kwaye ayinyibiliki ngokubanzi kwizinyibilikisi ezininzi zezinto eziphilayo. I-viscosity iyatshintsha kancinci xa ixabiso le-pH likuluhlu lwe-2-12, kodwa i-viscosity iyancipha ngaphaya kolu luhlu.

Isicelo

1. I-Hydroxyethyl cellulose (HEC) i-ether ye-cellulose e-non-ionic e-soluble ene-thickening enhle, ukumiswa, ukusabalalisa, i-emulsification, i-adhesion, ukubunjwa kwefilimu, ukukhuselwa komswakama kunye neendawo ezikhuselayo ze-colloid. Ngenxa yeempawu zayo ezikhethekileyo zomzimba kunye neekhemikhali, i-HEC isetyenziswa ngokubanzi kwiinkalo ezininzi, kubandakanywa kodwa ingaphelelanga ekutsalweni kweoli, iingubo, ukwakhiwa, ukutya kwamayeza, i-textiles, i-papermaking kunye ne-polymerization.
2. Kwintsimi yamachiza, ngaphezu kwe-thickener kunye ne-agent ekhuselayo, i-cellulose ye-hydroxyethyl nayo ineempembelelo zokuthambisa, i-hydrating, i-anti-aging, ukucocwa kwesikhumba kunye nokususa i-melanin. Ifanelekile ukwenza amathontsi eliso, izitshizi zempumlo, izisombululo zomlomo, njl njl. Inokunyusa i-viscosity yeyeza, iphucule izinga lokufunxa ichiza emzimbeni, kwaye yandise ukuzinza kwechiza ukuthintela ukubola kweziyobisi kunye ne-oxidation.
3. Kwishishini lezinto zokuthambisa, i-HEC isetyenziswa kakhulu ekwenzeni ishampu, i-conditioner, i-cream, i-lotion kunye nezinye iimveliso. Iyakwazi ukulungelelanisa i-viscosity kunye nokuthungwa kwezinto zokuthambisa ukuze kube lula ukuzisebenzisa kunye nokufunxa. Kwangaxeshanye, ikwanazo nefuthe lokuthambisa, inokuvala ukufuma, kwaye ithintele ukomisa kwesikhumba kunye nokuqhekeka.
4. Ukongeza, i-hydroxyethyl cellulose isetyenziswa kakhulu njenge-thickener, i-colorant kunye ne-preservative kwishishini lokutya, elinokunyusa i-viscosity kunye nokuthungwa kokutya kunye nokuphucula incasa kunye nomgangatho wokutya. Ingasetyenziswa kwakhona njenge-emulsifier kunye ne-stabilizer ukuthintela i-stratification yokutya kunye nemvula.
5. Ngokumalunga ne-acidity kunye ne-alkalinity ye-hydroxyethyl cellulose, ekubeni i-non-ionic cellulose ether class, ayikho i-acidic okanye i-alkaline. I-formula yayo yeekhemikhali (C2H6O2) n, ene-solubility efanelekileyo, ukuzinza kunye neempawu zokuqina, kwaye idlala indima ebalulekileyo kwiinkalo ezahlukeneyo zesicelo.
