Ethyl cellulose

Ethyl cellulose ndi chochokera ku cellulose, polima wachilengedwe wopezeka muzomera.Amapangidwa ndi zomwe cellulose ndi ethyl chloride pamaso pa chothandizira.Ethyl cellulose imagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana chifukwa cha mawonekedwe ake apadera komanso kusinthasintha.Nazi zina zofunika ndikugwiritsa ntchito kwa ethyl cellulose:

1. Insolubility m'madzi: Ethyl cellulose sasungunuka m'madzi, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsa ntchito komwe kumayenera kukana madzi.Katunduyu amalolanso kugwiritsidwa ntchito ngati chotchingira choteteza m'zamankhwala komanso ngati chotchinga pakupanga chakudya.
2. Kusungunuka mu Zosungunulira Zachilengedwe: Ethyl cellulose imatha kusungunuka mumitundu yambiri yamadzimadzi, kuphatikiza ethanol, acetone, ndi chloroform.Kusungunuka kumeneku kumapangitsa kuti zikhale zosavuta kupanga ndi kupanga zinthu zosiyanasiyana, monga zokutira, mafilimu, ndi inki.
3. Kutha Kupanga Mafilimu: Ethyl cellulose amatha kupanga mafilimu osinthika komanso olimba akayanika.Katunduyu amagwiritsidwa ntchito ngati zokutira pamapiritsi m'zamankhwala, pomwe amapereka chitetezo chazomwe zimagwira ntchito.
4. Thermoplasticity: Ethyl cellulose imawonetsa machitidwe a thermoplastic, kutanthauza kuti imatha kufewetsa ndikuwumbidwa ikatenthedwa kenako kukhazikika pakuzizira.Katunduyu amapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito pazomatira zosungunuka ndi mapulasitiki owumbika.
5. Chemical Inertness: Ethyl cellulose ndi inert ndi mankhwala ndipo kugonjetsedwa ndi zidulo, alkalis, ndi zambiri zosungunulira organic.Katunduyu amapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito muzopanga zomwe kukhazikika komanso kuyanjana ndi zinthu zina ndizofunikira.
6. Biocompatibility: Ethyl cellulose nthawi zambiri imawonedwa ngati yotetezeka (GRAS) kuti igwiritsidwe ntchito muzamankhwala, chakudya, ndi zodzikongoletsera.Sichiwopsezo ndipo sichikhala pachiwopsezo cha zotsatira zoyipa zikagwiritsidwa ntchito monga momwe amafunira.
7. Kutulutsidwa Kolamulidwa: Ethyl cellulose nthawi zambiri amagwiritsidwa ntchito popanga mankhwala kuti azitha kutulutsa zinthu zomwe zimagwira ntchito.Posintha makulidwe a zokutira za ethyl cellulose pamapiritsi kapena ma pellets, kuchuluka kwa mankhwalawa kumatha kusinthidwa kuti akwaniritse mbiri yayitali kapena yokhazikika.
8. Binder ndi Thickener: Ethyl cellulose amagwiritsidwa ntchito ngati binder ndi thickener mu ntchito zosiyanasiyana, kuphatikizapo inki, zokutira, ndi zomatira.Iwo bwino rheological zimatha formulations ndi kuthandiza kukwaniritsa ankafuna kugwirizana ndi mamasukidwe akayendedwe.

ethyl cellulose ndi polima yosunthika yomwe imagwiritsidwa ntchito mosiyanasiyana m'mafakitale monga mankhwala, chakudya, zodzoladzola, zokutira, ndi zomatira.Kuphatikizika kwake kwapadera kwa zinthu kumapangitsa kuti ikhale yofunika kwambiri pamapangidwe ambiri, komwe imathandizira kukhazikika, magwiridwe antchito, ndi magwiridwe antchito.
