Abantu abaningi abakwazi ukuhlukanisa phakathi kwe-hydroxyethyl cellulose ne-ethyl cellulose. I-Hydroxyethyl cellulose ne-ethyl cellulose yizinto ezimbili ezihlukene. Banezici ezilandelayo.
1 I-Hydroxyethyl cellulose:
Njenge-surfactant engeyona i-ionic, ngaphezu kokuqina, ukumisa, ukubopha, ukuntanta, ukwenza ifilimu, ukuhlakazeka, ukugcina amanzi nokuhlinzeka ngama-colloid okuvikela, futhi inalezi zakhiwo ezilandelayo:
1. I-HEC iyancibilika emanzini ashisayo noma abandayo, futhi ayidli ekushiseni okuphezulu noma ekubiliseni, okuyenza ibe nezici eziningi zokuncibilika kanye nezici ze-viscosity, kanye ne-gelation engashisi;
2. Ayiyona i-ionic futhi ingahlala kanye nohlu olubanzi lwama-polymers ancibilikayo emanzini, ama-surfactants nosawoti, futhi iyi-colloidal thickener enhle kakhulu equkethe izixazululo ze-electrolyte eziphezulu zokugxila;
3. Umthamo wokugcina amanzi uphakeme ngokuphindwe kabili kunalowo we-methyl cellulose, futhi unokulawula ukugeleza okungcono.
4. Uma kuqhathaniswa ne-methyl cellulose eyaziwayo kanye ne-hydroxypropyl methyl cellulose, ikhono lokuhlakaza le-HEC libi kakhulu, kodwa i-colloid evikelayo inekhono eliqine kakhulu.
2 I-Ethyl cellulose
I-non-ionic cellulose ether engancibiliki emanzini kodwa encibilika kuzincibilikisi zemvelo. Inezici ezilandelayo:
1. Akulula ukushisa.
2. Ukuzinza okuhle kwe-thermal kanye ne-thermoplasticity enhle kakhulu.
3. Akukho ukushintsha kombala ekukhanyeni kwelanga.
4. Ukuvumelana nezimo okuhle.
5. Izakhiwo ezinhle ze-dielectric.
6. Inokumelana okuhle kakhulu kwe-alkali nokumelana ne-asidi ebuthakathaka.
7. Ukusebenza okuhle kokuguga.
8. Ukumelana kahle nosawoti, amakhaza kanye nokumuncwa komswakama.
9. Izinzile kumakhemikhali, ukugcina isikhathi eside ngaphandle kokuwohloka.
10. Ihambisana nama-resin amaningi kanye nokuhambisana okuhle nawo wonke ama-plasticizers.
11. Kulula ukushintsha umbala ngaphansi kwemvelo eqinile ye-alkaline nezimo zokushisa.
