Kodi pali kusiyana kotani pakati pa hydroxethyl cellulose ndi ethyl cellulose

Anthu ambiri sanganene kusiyana pakati pa hydroxyethyl cellulose ndi ethyl cellulose. Hydroxyethyl cellulose ndi ethyl cellulose ndi zinthu ziwiri zosiyana. Ali ndi izi.

1
Hydroxyethyl cellulose:
Monga chosungira chosagwirizana, kuphatikizira, kuyimitsa, kumangiriza, kumangika, kupanga mafilimu, kumalimbikitsanso ma coloid, omwe ali ndi zinthu zotsatirazi:
1. Hec amasungunuka m'madzi otentha kapena ozizira, ndipo osayendetsa kutentha kwambiri kapena kuwira, kuwononga mawonekedwe osiyanasiyana komanso owoneka bwino;
2. Sikuti ndi ionic ndipo imatha kukhala yolumikizana ndi ma pointer ena osungunuka madzi, ogwiritsa ntchito ndi mchere, ndipo ndi njira yabwino kwambiri yothandizira kwambiri yama elecrolyte;
3. Kuchuluka kwa madzi ndikokwera kwambiri ngati kwa methyl cellulose, ndipo ili ndi njira yabwino kwambiri.
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.
