Hydroxyethyl cellulose le ethyl cellulose

Hydroxyethyl cellulose le ethyl cellulose ke dintho tse pedi tse fapaneng. Di na le dibopeho tse latelang.

Hydroxyethyl cellulose

Jwalo ka surfactant e seng ya ionic, ntle le ho teteana, ho emisa, ho tlama, ho phaphamala, ho etsa filimi, ho qhalanya, ho boloka metsi le ho fana ka di-colloid tse sireletsang, e boetse e na le thepa e latelang:

1. HEC e qhibiliha metsing a chesang kapa a batang, 'me ha e potlake mochesong o phahameng kapa e belang, hoo e nang le mefuta e mengata ea litšobotsi tsa ho qhibiliha le ho teteana, le ho se chese ha mocheso;

2. Ntho e seng ionic ka boeona e ka phela hammoho le mefuta e mengata e fapaneng ea li-polymer tse ling tse qhibilihang ka metsing, li-surfactant le letsoai, 'me ke setenya se setle sa colloidal se nang le litharollo tsa electrolyte tse nang le mahloriso a mangata;

3. Bokgoni ba ho boloka metsi bo phahame habeli ho feta ba methyl cellulose, mme bo na le taolo e betere ya phallo;

4. Ha ho bapisoa le methyl cellulose e tsebahalang le hydroxypropyl methyl cellulose, bokhoni ba ho qhala ha HEC ke bo bobe ka ho fetisisa, empa colloid e sireletsang e na le bokhoni bo matla ka ho fetisisa.

Selulose ea ethyl

Ke ether ea cellulose e seng ea ionic e sa qhibiliheng metsing empa e qhibilihang ka har'a metsoako ea lintho tse phelang. E na le litšobotsi tse latelang:

1. Ha ho bonolo ho e chesa.

2. Botsitso bo botle ba mocheso le thermoplasticity e ntle haholo.

3. Ha ho na ho fifala ha mmala ho ya ka kganya ya letsatsi.

4. Ho tenyetseha ho hotle.

5. Thepa e ntle ea dielectric.

6. E na le khanyetso e ntle ea alkali le khanyetso e fokolang ea asiti.

7. Tshebetso e ntle ea ho thibela botsofali.

8. Ho hanyetsa letsoai, serame le mongobo hantle.

9. E tsitsitse lik'hemik'hale, e bolokoa nako e telele ntle le ho senyeha.

10. E lumellana le li-resin tse ngata 'me e lumellana hantle le li-plasticizer tsohle.

11. Ho bonolo ho fetola 'mala tlas'a tikoloho e matla ea alkaline le maemo a mocheso.
