Kodi pali kusiyana kotani pakati pa hydroxyethyl cellulose ndi ethyl cellulose?

Anthu ambiri sangathe kusiyanitsa pakati pa hydroxyethyl cellulose ndi ethyl cellulose.Hydroxyethyl cellulose ndi ethyl cellulose ndi zinthu ziwiri zosiyana.Iwo ali ndi makhalidwe otsatirawa.

1 Hydroxyethyl cellulose:
Monga surfactant yopanda ionic, kuphatikiza kukhuthala, kuyimitsa, kumanga, kuyandama, kupanga filimu, kubalalitsa, kusunga madzi ndikupereka ma colloids oteteza, ilinso ndi izi:
1. HEC imasungunuka m'madzi otentha kapena ozizira, ndipo sichitha kutentha kwambiri kapena kutentha, kumapangitsa kuti ikhale ndi mitundu yambiri ya solubility ndi viscosity, ndi gelation yopanda kutentha;
2. Ndizopanda ma ionic ndipo zimatha kukhala pamodzi ndi ma polima ena osungunuka m'madzi, ma surfactants ndi mchere, ndipo ndi abwino kwambiri a colloidal thickener omwe ali ndi ma electrolyte apamwamba kwambiri;
3. Mphamvu yosungira madzi imakhala yowirikiza kawiri kuposa ya methyl cellulose, ndipo imakhala ndi malamulo oyendetsera bwino.
4. Poyerekeza ndi methyl cellulose yodziwika bwino ndi hydroxypropyl methyl cellulose, mphamvu yobalalika ya HEC ndiyoipa kwambiri, koma colloid yotetezera imakhala ndi mphamvu zolimba kwambiri.

2 Ethyl cellulose
Ndi non-ionic cellulose ether amene sasungunuke m'madzi koma sungunuka mu zosungunulira organic.Lili ndi izi:

1. Zosavuta kuwotcha.
2. Kukhazikika kwamafuta abwino komanso thermoplasticity yabwino kwambiri.
3. Palibe kusinthika kwa kuwala kwa dzuwa.
4. Kusinthasintha kwabwino.
5. Zinthu zabwino za dielectric.
6. Ili ndi kukana kwambiri kwa alkali komanso kufooka kwa asidi.
7. Kuchita bwino koletsa kukalamba.
8. Kukana kwabwino kwa mchere, kuzizira ndi kuyamwa kwa chinyezi.
9. Kukhazikika kwa mankhwala, kusungidwa kwa nthawi yaitali popanda kuwonongeka.
10. Yogwirizana ndi ma resins ambiri ndikugwirizana bwino ndi mapulasitiki onse.
11. N'zosavuta kusintha mtundu pansi pa malo amphamvu amchere komanso kutentha.
