I-Hydroxyethyl cellulose ne-ethyl cellulose

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

IHydroxYethyl Cellulose

Njenge-survic engekho emthethweni, ngaphezu kokuqina, ukumisa, ukubopha, ukugcwala, ukuhlasela amafilimu, ukusabalalisa, ukugcina amanzi nokuhlinzeka ngezakhiwo ezilandelayo:

1. I-HEC incane emanzini ashisayo noma abandayo, futhi ayihlanganisi ekushiseni okuphezulu noma ukubilisa, ukuze ibe nohlobo olunhlobonhlobo lwe-soubity kanye ne-viscosity, ne-gelation engeyona eyeshisayo;

4. Uma uqhathanisa ne-methyl cellulose ye-methyls ne-hydroxypropyll methyl cellulose, amandla asabalalisayo ka-HEC yimbi kakhulu, kepha i-colloid evikelayo inekhono eliqine kakhulu.

I-ethyl cellulose

Yi-ether ye-cellulose engeyona eye-ionic okungekho emthethweni emanzini kodwa incibilika ku-organic solvents. Inezici ezilandelayo:

1. Akulula ukushiswa.

2. Ukuqina okuhle okushisayo kanye ne-thermoplasticity enhle kakhulu.

3. AKUKHO BUNGAKWAZI UKUZEZA.

4. Ukuvumelana nezimo okuhle.

I-5. Izakhiwo ezinhle ze-dielectric.

I-6. Inokumelana okuhle kwe-alkali nokumelana nobuthakathaka kwe-acid.

7. Ukusebenza okuhle kokulwa nokuguga.

8. Ukumelana okuhle kosawoti, ukumunca okubandayo kanye nomswakama.

9. Izitebelelo kumakhemikhali, ukugcinwa isikhathi eside ngaphandle kokuwohloka.

10. Iyahambisana nama-resins amaningi kanye nokuhambisana okuhle nawo wonke amapulasitiki.

11. Kulula ukushintsha umbala ngaphansi kwemvelo eqinile ye-alkaline kanye nezimo zokushisa.
