Kodi HEC material ndi chiyani?

HEC (Hydroxyethyl Cellulose) ndi polima wopangidwa kuchokera ku cellulose, polima wachilengedwe wopezeka muzomera. Ndi polima yopanda ionic, yosungunuka m'madzi yomwe imagwiritsidwa ntchito pazinthu zosiyanasiyana, kuphatikiza zinthu zosamalira anthu, mankhwala, zakudya, komanso ntchito zamafakitale. HEC ndi zinthu zosunthika zomwe zili ndi katundu wambiri, kuphatikizapo kukhuthala, kukhazikika, kuyimitsa, ndi kutsekemera.

HEC imapangidwa ndi njira yotchedwa etherification, yomwe cellulose imathandizidwa ndi ethylene oxide kupanga polyether. Chotsatira chake ndi polima yopangidwa ndi poliyesi yokhala ndi zinthu zambiri, kuphatikiza kukhuthala, kuyimitsa, ndi emulsifying. HEC ndi ufa woyera, wopanda fungo, komanso wosakoma womwe umasungunuka m'madzi ndi zosungunulira zina za polar.

HEC imagwiritsidwa ntchito pazinthu zosiyanasiyana, kuphatikizapo zinthu zosamalira anthu, mankhwala, zakudya, ndi mafakitale. Pazinthu zosamalira anthu, HEC imagwiritsidwa ntchito ngati thickener, stabilizer, ndi emulsifier. Amagwiritsidwa ntchito kulimbitsa ma shampoos, zoziziritsa kukhosi, zodzoladzola, zopaka mafuta, komanso kukhazikika ndi kusungunula zosakaniza zamafuta ndi madzi. Pazamankhwala, HEC imagwiritsidwa ntchito ngati woyimitsa, komanso stabilizer ndi thickener. Muzakudya, HEC imagwiritsidwa ntchito ngati stabilizer, thickener, and emulsifier. Amagwiritsidwa ntchito kulimbitsa ma sauces, gravies, soups, komanso kukhazikika ndi kusakaniza mafuta ndi madzi.

M'mafakitale, HEC imagwiritsidwa ntchito ngati thickener, stabilizer, ndi emulsifier. Amagwiritsidwa ntchito kulimbitsa utoto, zokutira, zomatira, komanso kukhazikika ndi kusungunula zosakaniza zamafuta ndi madzi. HEC imagwiritsidwanso ntchito pobowola ndi kupanga mafuta ndi gasi, monga kusintha kwa viscosity, komanso ngati gelling agent.

HEC ndi zinthu zosunthika zomwe zimakhala ndi katundu wambiri, zomwe zimapangitsa kuti zikhale zoyenera pa ntchito zosiyanasiyana. Ndi polima yopanda ionic, yosungunuka m'madzi yomwe imagwiritsidwa ntchito kulimbitsa, kukhazikika, komanso kusungunula zosakaniza zamafuta ndi madzi. Amagwiritsidwa ntchito pazinthu zosamalira anthu, mankhwala, zakudya, ndi mafakitale. HEC ndi zinthu zotetezeka komanso zothandiza zomwe zimagwiritsidwa ntchito pazinthu zosiyanasiyana.
