Chiyambi cha Hydroxyethylcellulose (HEC):
Hydroxyethyl cellulose ndi chochokera ku cellulose, polysaccharide yopezeka mwachilengedwe yomwe imapezeka m'makoma a maselo.Ma cellulose amapangidwa ndi mayunitsi obwerezabwereza a glucose olumikizidwa pamodzi ndi β-1,4 glycosidic bond.Hydroxyethyl cellulose imapezeka mwa kusintha mapadi kudzera pakuyambitsa magulu a hydroxyethyl (-CH2CH2OH) pamsana wake.
Ndondomeko Yopanga:
Etherification ya Cellulose: Kupanga kwa HEC kumaphatikizapo etherification ya cellulose.Izi zimayamba ndi cellulose yochokera ku zamkati zamatabwa kapena ma linter a thonje.
Zomwe zimachitika ndi Ethylene Oxide: Ma cellulose amapangidwa ndi ethylene oxide pansi pamikhalidwe yamchere.Izi zimatsogolera m'malo mwa magulu a hydroxyl pamsana wa cellulose ndi magulu a hydroxyethyl, zomwe zimapangitsa kuti hydroxyethyl cellulose.
Kuyeretsedwa: Chogulitsacho chimatsukidwa kuti chichotse ma reagents osakhudzidwa ndi zinthu zam'mbali.
Makhalidwe a Hydroxyethylcellulose:
Kusungunuka: HEC imasungunuka m'madzi ozizira komanso otentha, kupanga zomveka bwino mpaka zosungunulira pang'ono kutengera ndende.
Viscosity: Imawonetsa khalidwe la pseudoplastic, kutanthauza kuti kukhuthala kwake kumachepa ndi kumeta ubweya wambiri.Kukhuthala kwa mayankho a HEC kumatha kusinthidwa ndi zinthu zosiyanasiyana monga ndende komanso kuchuluka kwa m'malo.
Katundu Wopanga Mafilimu: HEC imatha kupanga mafilimu osinthika komanso ogwirizana, ndikupangitsa kuti ikhale yothandiza pamapulogalamu osiyanasiyana pomwe kupanga mafilimu kumafunikira.
Thickening Agent: Chimodzi mwazinthu zazikulu zogwiritsira ntchito HEC ndi monga chowonjezera pamitundu yosiyanasiyana, monga zodzoladzola, mankhwala, ndi zinthu zosamalira anthu.
Kugwiritsa ntchito hydroxyethyl cellulose:
Zodzoladzola ndi Zosamalira Munthu: HEC imagwiritsidwa ntchito kwambiri muzodzoladzola ndi zinthu zosamalira munthu monga thickener, stabilizer, ndi kupanga mafilimu muzinthu monga mafuta odzola, mafuta odzola, shampoos, ndi mankhwala otsukira mano.
Mankhwala: M'mapangidwe amankhwala, HEC imagwira ntchito ngati woyimitsa, womangira, ndi wowongolera-kutulutsa matrix mu zokutira mapiritsi ndi zopangira pakamwa.
Utoto ndi Zopaka: HEC imagwiritsidwa ntchito mu utoto wopangidwa ndi madzi ndi zokutira monga chowonjezera ndi rheology modifier kuwongolera kukhuthala ndikuwongolera magwiridwe antchito.
Makampani a Chakudya: M'makampani azakudya, HEC imagwiritsidwa ntchito ngati chowonjezera komanso chokhazikika pazinthu monga sosi, zovala, ndi mkaka.
Mkangano Wachilengedwe Kapena Wopanga:
Gulu la hydroxyethylcellulose ngati lachilengedwe kapena lopangidwa limakhala lotsutsana.Nawa mikangano ya mbali zonse ziwiri:
Zotsutsana za Kugawikana Monga Zopangidwa:
Kusintha kwa Chemical: HEC imachokera ku cellulose kudzera mu njira yosinthira mankhwala yomwe imakhudza momwe cellulose imayendera ndi ethylene oxide.Kusintha kwamankhwala kumeneku kumatengedwa ngati kupanga m'chilengedwe.
Industrial Production: HEC imapangidwa makamaka kudzera m'mafakitale okhudzana ndi machitidwe oyendetsedwa ndi masitepe oyeretsa, omwe ndi ofanana ndi kupanga kopanga kopanga.
Digiri Yosintha: Mlingo wolowa m'malo mu HEC ukhoza kuwongoleredwa bwino panthawi ya kaphatikizidwe, kuwonetsa chiyambi chopangidwa.
Zotsutsana za Kugawa Monga Zachilengedwe:
Wochokera ku Cellulose: HEC imachokera ku cellulose, polima wachilengedwe wopezeka muzomera.
Gwero Longowonjezedwanso: Cellulose, zomwe zimayambira kupanga HEC, zimachokera kuzinthu zongowonjezedwanso monga zamkati zamatabwa ndi thonje.
Biodegradability: Monga cellulose, HEC ndi biodegradable, kusweka kukhala zinthu zopanda vuto m'chilengedwe pakapita nthawi.
Kugwira Ntchito Kufanana ndi Ma cellulose: Ngakhale kusinthidwa kwamankhwala, HEC imasungabe zinthu zambiri za cellulose, monga kusungunuka m'madzi ndi biocompatibility.
hydroxyethylcellulose ndi polima wosunthika wopangidwa kuchokera ku cellulose kudzera munjira yosintha mankhwala.Ngakhale kuti kupanga kwake kumaphatikizapo machitidwe opangira ndi mafakitale, pamapeto pake amachokera ku gwero lachilengedwe komanso losinthika.Mtsutso wokhudza ngati HEC iyenera kutchulidwa kuti ndi yachilengedwe kapena yopangidwa imasonyeza zovuta zofotokozera mawuwa potengera ma polima achilengedwe osinthidwa.Komabe, kuwonongeka kwake kwachilengedwe, kubwezeredwanso, komanso kufanana kwa cellulose kukuwonetsa kuti ili ndi mawonekedwe azinthu zachilengedwe komanso zopangira, zomwe zimalepheretsa malire pakati pa magulu awiriwa.
