Hydroxyethyl cellulose ndi ethyl cellulose

Hydroxyethyl cellulose ndi ethyl cellulose ndi zinthu ziwiri zosiyana. Ali ndi izi.

Hydroxyethyl cellulose

Monga chosungira chosagwirizana, kuphatikizira, kuyimitsa, kumangiriza, kumangika, kupanga mafilimu, kumalimbikitsanso ma coloid, omwe ali ndi zinthu zotsatirazi:

1. Hec imasungunuka m'madzi otentha kapena ozizira, ndipo osayendetsa kutentha kwambiri kapena kuwira, kotero kuti ili ndi mawonekedwe osiyanasiyana komanso owoneka bwino;

2. Osati anic yokha ikhoza kukhala yolumikizana ndi ma pointer ena osungunuka madzi osungunuka madzi, okonda ndi mchere, ndipo ndi njira yabwino kwambiri yothandizira kwambiri yama elecrorrolyte yokhala;

3. Kuchuluka kwa madzi ndikokwera kwambiri kuposa kwa methyl cellulose, ndipo ili ndi lamulo labwino;

4. Poyerekeza ndi methyl yovomerezeka ya cellose ndi hydroxypropyl methyl celyose, luso lofalitsidwa la hec ndiye loyipitsitsa, koma colloid yoteteza imakhala ndi mphamvu yolimba.

Ethyl cellulose

Ndi ma ether cellulose ether omwe amakhutira m'madzi koma sungunuka m'malo okhazikika. Ili ndi izi:

1. Osasavuta kuwotcha.

2.

3. Palibe kusinthanitsa ndi kuwala kwa dzuwa.

4. Kusinthasintha.

5. Katundu wabwino wa dieclectic.

6. Ili ndi vuto lalikulu la alkali ndi zofooka acid.

7..

8. Kukaniza kwabwino mchere, kuzizira komanso chinyezi.

9. Kukhazikika ku mankhwala, kusungidwa kwa nthawi yayitali popanda kuwonongeka.

10. Kugwirizana ndi ma resin komanso kuyenderana bwino ndi mafayilo onse.

11. Ndikosavuta kusintha mtundu pansi pa malo otetezeka a alkaline ndi mitembo.
