I-Hydroxyethyl cellulose ne-ethyl cellulose

I-Hydroxyethyl cellulose ne-ethyl cellulose yizinto ezimbili ezihlukene. Banezici ezilandelayo.

I-Hydroxyethyl cellulose

Njenge-surfactant engeyona i-ionic, ngaphezu kokuqina, ukumisa okwesikhashana, ukubopha, ukuntanta, ukwenza ifilimu, ukusabalalisa, ukugcina amanzi kanye nokuhlinzeka ngama-colloid okuzivikela, futhi inezindawo ezilandelayo:

1. I-HEC iyancibilika emanzini ashisayo noma abandayo, futhi ayidli ngokushisa okuphezulu noma ukubila, ukuze ibe nezici eziningi zokuncibilika kanye nezici ze-viscosity, kanye ne-gelation engashisi;

2. I-non-ionic ngokwayo ingahlala kanye nohlu olubanzi lwama-polymers ancibilikayo emanzini, ama-surfactants nama-salts, futhi iyi-thickener ye-colloidal 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.

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, isitoreji sesikhathi 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.
