Hydroxyethyl cellulose le ethyl cellulose

Hydroxyethyl cellulose le ethyl cellulose ke lintho tse peli tse fapaneng. Ba na le litšobotsi tse latelang.

Hydroxyethyl cellulose

Joalo ka "non-ionic surfactant", ntle le ho tenya, ho emisa, ho tlama, ho phaphamala, ho etsa filimi, ho qhalakanya, ho boloka metsi le ho fana ka li-colloids tse sireletsang, e boetse e na le thepa e latelang:

1. HEC e qhibiliha ka metsing a chesang kapa a batang, 'me ha e na mocheso o phahameng kapa o belang, e le hore e be le mefuta e mengata ea ho qhibiliha le litšoaneleho tsa viscosity, le gelation e sa chesang;

2. The non-ionic ka boeona e ka phela hammoho le mefuta e mengata e mengata ea li-polymers tse qhibilihang ka metsing, li-surfactants le letsoai, 'me ke motsoako o babatsehang oa colloidal o nang le litharollo tse phahameng tsa electrolyte;

3. Matla a ho boloka metsi a phahame ka makhetlo a mabeli ho feta a methyl cellulose, 'me a na le taolo e ntle ea phallo;

4. Ha ho bapisoa le methyl cellulose e tsejoang le hydroxypropyl methyl cellulose, bokhoni ba ho qhalakanngoa ba HEC bo bobe ka ho fetisisa, empa colloid e sireletsang e na le matla a matla ka ho fetisisa.

Ethyl cellulose

Ke non-ionic cellulose ether e sa qhibiliheng metsing empa e qhibiliha ka har'a metsoako ea tlhaho. E na le litšobotsi tse latelang:

1. Ha ho bonolo ho chesa.

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

3. Ha ho na khanya ea letsatsi.

4. Ho tenyetseha hantle.

5. Lintho tse ntle tsa dielectric.

6. E na le khanyetso e ntle ea alkali le ho hanyetsa acid e fokolang.

7. Ts'ebetso e ntle ea ho thibela botsofali.

8. Ho hanyetsa hantle ho noa letsoai, serame le mongobo.

9. E tsitsitseng ho lik'hemik'hale, polokelo ea nako e telele ntle le ho senyeha.

10. E lumellana le li-resin tse ngata le ho lumellana hantle le li-plasticizers tsohle.

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