Kodi pali kusiyana kotani pakati pa HEC ndi HEMC?

HEC (Hydroxyethyl Cellulose) ndi HEMC (Hydroxyethyl Methyl Cellulose) onse ndi ma polima opangidwa kuchokera ku cellulose, polysaccharide yopezeka mwachilengedwe yomwe imapezeka muzomera.Zonsezi zimagwiritsidwa ntchito ngati zonenepa, zolimbitsa thupi, ndi zopangira ma emulsifiers pazinthu zosiyanasiyana, kuphatikiza utoto ndi zokutira, chakudya, mankhwala, zodzoladzola, ndi ntchito zamafakitale.

Kusiyana kwakukulu pakati pa HEC ndi HEMC kuli mu kapangidwe kake ka mankhwala.HEC ndi yochokera ku cellulose yopanda ionic, pomwe HEMC ndi yochokera ku ionic cellulose.HEC imapangidwa ndi gulu limodzi la hydroxyethyl lomwe limagwirizanitsidwa ndi cellulose msana, pamene HEMC imapangidwa ndi magulu awiri a hydroxyethyl omwe amamangiriridwa ku msana wa cellulose.

HEC ndi polima wosungunuka m'madzi womwe umagwiritsidwa ntchito ngati thickening muzinthu zosiyanasiyana, kuphatikiza utoto & zokutira, chakudya, mankhwala, ndi zodzola.Amagwiritsidwa ntchito kuonjezera mamasukidwe akayendedwe a chinthu, kuwongolera kukhazikika kwake, ndikupereka mawonekedwe osalala.Amagwiritsidwanso ntchito ngati emulsifier kuti athandizire kuti zosakaniza zisalekanitse.

HEMC imakhalanso ndi polima yosungunuka m'madzi yomwe imagwiritsidwa ntchito ngati thickening agent.Amagwiritsidwa ntchito pazinthu zosiyanasiyana, kuphatikizapo zomangamanga, chakudya, mankhwala, ndi zodzoladzola.Amagwiritsidwa ntchito kuonjezera mamasukidwe akayendedwe a chinthu, kuwongolera kukhazikika kwake, ndikupereka mawonekedwe osalala.Amagwiritsidwanso ntchito ngati emulsifier kuti athandizire kuti zosakaniza zisalekanitse.

HEC imagwiritsidwa ntchito kwambiri popanga utoto ndi zokutira, pomwe HEMC imagwiritsidwa ntchito kwambiri pomanga ndi zodzoladzola.HEC imakhala yothandiza kwambiri pakuwonjezera kukhuthala kwa chinthu kuposa HEMC, komanso imakhala yokhazikika munjira za acidic ndi zamchere.HEMC imakhala yothandiza kwambiri popereka mawonekedwe osalala ku chinthu kuposa HEC, komanso imakhala yokhazikika pakutentha kwambiri.

Mwachidule, kusiyana kwakukulu pakati pa HEC ndi HEMC kuli mu kapangidwe kake ka mankhwala.HEC ndi yochokera ku cellulose yopanda ionic, pomwe HEMC ndi yochokera ku ionic cellulose.HEC imagwiritsidwa ntchito kwambiri popaka utoto & zokutira, zotsukira, pomwe HEMC imagwiritsidwa ntchito kwambiri pomanga ndi zodzoladzola.HEC imakhala yothandiza kwambiri pakuwonjezera kukhuthala kwa chinthu, pomwe HEMC imakhala yothandiza kwambiri popereka mawonekedwe osalala.
