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 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.
