Phapang ke efe pakeng tsa hydroxyethyl cellulose le ethyl cellulose?

Batho ba bangata ha ba tsebe phapang pakeng tsa hydroxyethyl cellulose le ethyl cellulose. Hydroxyethyl cellulose le ethyl cellulose ke lintho tse peli tse fapaneng. Li na le litšobotsi tse latelang.

1 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, e leng se etsang hore e be le mefuta e mengata ea litšobotsi tsa ho qhibiliha le ho teteana, le ho se chese ha mocheso;
2. Ha e na ionic mme e ka phela hammoho le mefuta e mengata ya di-polymer tse ding tse qhibilihang ka metsing, di-surfactant le matswai, mme ke sethibisi se setle sa colloidal se nang le ditharollo 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.

2 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.
