Kodi hydroxyethyl cellulose amapangidwa kuchokera chiyani?

Hydroxyethyl cellulose (HEC) ndi polima wopangidwa kuchokera ku cellulose, polysaccharide yopezeka mwachilengedwe yomwe imapezeka muzomera.Ndi ufa woyera, wosungunuka m'madzi womwe umagwiritsidwa ntchito ngati thickening, suspending, and stabilizing agents muzinthu zosiyanasiyana, kuphatikizapo zodzoladzola, mankhwala, zotsukira, ndi zakudya.

HEC imapangidwa ndikuchitapo kanthu pa cellulose ndi ethylene oxide, mankhwala omwe amachokera ku ethylene, mpweya wa hydrocarbon.Ethylene oxide imakhudzidwa ndi magulu a hydroxyl pa mamolekyu a cellulose, kupanga maulalo a ether pakati pa mamolekyu a cellulose.Izi zimapanga polima yolemera kwambiri kuposa cellulose yoyambirira, ndipo imapatsa polimayo mphamvu zake zosungunuka m'madzi.

HEC imagwiritsidwa ntchito pazinthu zosiyanasiyana, kuphatikizapo zodzoladzola, mankhwala, zotsukira, ndi zakudya.Mu zodzoladzola, amagwiritsidwa ntchito ngati thickening wothandizira, suspending wothandizira, ndi stabilizer.Mu mankhwala, amagwiritsidwa ntchito ngati binder, disintegrant, and suspending agent.Mu zotsukira, amagwiritsidwa ntchito ngati thickening wothandizira, kuyimitsa wothandizira, ndi stabilizer.Muzakudya, zimagwiritsidwa ntchito ngati thickening, suspending agent, ndi stabilizer.

HEC imagwiritsidwanso ntchito pobowola mafuta ndi gasi, komwe imagwiritsidwa ntchito kuonjezera kukhuthala kwamadzi obowola ndikuchepetsa kutayika kwamadzi kuchokera pamapangidwe.Amagwiritsidwanso ntchito popanga mapepala, komwe amagwiritsidwa ntchito kuonjezera mphamvu ndi kuuma kwa pepala.

HEC ndi zinthu zopanda poizoni, zosakwiyitsa, komanso zopanda allergenic, zomwe zimapangitsa kuti zikhale zotetezeka kuti zigwiritsidwe ntchito pazinthu zosiyanasiyana.Komanso ndi biodegradable, kupanga izo kusankha bwino chilengedwe.
