Kufunikira ndi kugwiritsa ntchito kwa hydroxyethyl cellulose

1. Katundu wa hydroxyethyl cellulose

Izi ndizoyera kapena zoyera zachikasu zopanda mafuta komanso zosavuta kuyenda ufa, 40 mesh sieve ≥9%; kutentha kofewa: 135-140 ° C; Kuwonekera kwa kachulukidwe kowoneka: 0.35-0.61g / ml; Kutentha kutentha: 205-210 ° C; Kuwotcha liwiro pang'onopang'ono; Kutentha kwa Equilium: 23 ° C; 6% pa 50% rh, 29% pa 84% rh.

Imasungunuka m'madzi onse ozizira ndi madzi otentha, ndipo nthawi zambiri mumasungunuka kwambiri. Makutu amasintha pang'ono mu mtundu wa pH yamtengo 2-12, koma ma viscy akuchepera kupitirira izi.

2. Malo ofunikira

Monga osagwirizana ndi ionic, hydroxethyl cellulose ili ndi zotsatirazi kuwonjezera, kuyimitsa, kuyandama, kukonza mafilimu,

1. Hec amasungunuka m'madzi otentha kapena madzi ozizira, ndipo osayendetsa kutentha kwambiri kapena kuwira, komwe kumapangitsa kuti kukhala ndi kusungunuka kosiyanasiyana, mawonekedwe a ma victory komanso miyala yamtengo wapatali.

2. Sikuti ndi ionic ndipo imatha kukhala yolumikizana ndi ma pointer ena osungunuka madzi, okonda, komanso mchere. Ndibwino kwambiri cololodal yothetsera mavuto ambiri a electrolyte.

3. Kuchuluka kwa madzi ndikokwera kwambiri ngati kwa methyl cellulose, ndipo ili ndi njira yabwino kwambiri.

4. Poyerekeza ndi methyl cellulose ndi hydroxypropyl methy cellose, hec imakhala ndi kuthekera kovuta kwambiri, koma kuthekera kolimba koteteza kwambiri.

3. Kugwiritsa ntchito hydroxyethyl cellulose

Nthawi zambiri amagwiritsa ntchito ngati oteteza, othandizira, zomata, okhazikika, mafuta, mafuta, mafuta, mafuta a matrix, omwe amathanso kugwiritsidwa ntchito ngati chakudya.
