Kodi HEC ndi yachilengedwe?
HEC sizinthu zachilengedwe. Ndi polima yopangidwa kuchokera ku cellulose, yomwe ndi polysaccharide yopezeka mwachilengedwe yomwe imapezeka muzomera. Hydroxyethyl cellulose HEC ndi polima wosungunuka m'madzi womwe umagwiritsidwa ntchito mosiyanasiyana, kuphatikiza ngati thickening agent, emulsifier, stabilizer, and suspending agent.
HEC imapangidwa pochita ma cellulose ndi ethylene oxide, mankhwala opangidwa ndi petroleum. Izi zimapanga polima ndi chikhalidwe cha hydrophilic (chokonda madzi), chomwe chimapangitsa kuti chisungunuke m'madzi. HEC ndi ufa woyera, wopanda fungo wopanda fungo komanso wosakoma. Sichikhoza kuyaka ndipo chimakhala chokhazikika pamitundu yosiyanasiyana ya kutentha ndi pH.
HEC imagwiritsidwa ntchito m'mafakitale osiyanasiyana, kuphatikizapo chakudya, mankhwala, zodzoladzola, ndi zinthu zosamalira anthu. Mu chakudya, amagwiritsidwa ntchito ngati thickener, emulsifier, ndi stabilizer. Muzamankhwala, amagwiritsidwa ntchito ngati kuyimitsidwa kwapaintaneti ndi binder yamapiritsi. Muzodzoladzola ndi zinthu zosamalira anthu, zimagwiritsidwa ntchito ngati thickener ndi stabilizer.
HEC nthawi zambiri imawonedwa ngati yotetezeka kuti igwiritsidwe ntchito m'zakudya, mankhwala, ndi zodzoladzola. Imavomerezedwa kuti igwiritsidwe ntchito ku United States ndi Europe, ndipo yalembedwa pamndandanda wa FDA's Generally Recognized as Safe (GRAS).
HEC sizinthu zachilengedwe, koma ndizotetezeka komanso zothandiza zomwe zimagwiritsidwa ntchito kwambiri m'mafakitale ambiri. Ndilo gawo lofunikira lazinthu zambiri, ndipo kusinthasintha kwake kumapangitsa kuti likhale lofunika kwambiri pa ntchito zambiri.
