Batho ba bangata ha ba tsebe phapang lipakeng tsa hydroxyethyl cellulose le ethyl cellulose. Hydroxyethyl cellulose le ethyl cellulose ke lintho tse peli tse fapaneng. Ba na le litšobotsi tse latelang.
1 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 chese ka mocheso o phahameng kapa ho belisoa, ho etsa hore e be le mefuta e mengata ea ho qhibiliha le litšoaneleho tsa viscosity, le gelation e se nang mocheso;
2. Ha e na ionic 'me 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 ho phalla.
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.
2 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 ha letsoai, serame le ho monya 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.
