Cellulose, hydroxyethyl ether (MW 1000000)

Cellulose hydroxyethyl etherndi chochokera ku cellulose, polima wachilengedwe wopezeka m'makoma a cell a zomera. Kusintha kwa hydroxyethyl ether kumaphatikizapo kuyambitsa magulu a hydroxyethyl ku mapangidwe a cellulose. Kulemera kwa molekyulu (MW) yotchulidwa kuti 1,000,000 mwina imatanthawuza kulemera kwa maselo a cellulose hydroxyethyl ether. Nazi mfundo zazikuluzikulu za cellulose hydroxyethyl ether yokhala ndi molekyulu yolemera 1,000,000:

1. Kapangidwe ka Chemical:
   • Ma cellulose hydroxyethyl ether amachokera ku cellulose pochita ndi ethylene oxide, zomwe zimapangitsa kuti magulu a hydroxyethyl alowe msana wa cellulose.
2. Kulemera kwa Molecular:
   • Kulemera kwa molekyulu ya 1,000,000 kumasonyeza kulemera kwa maselo a cellulose hydroxyethyl ether. Mtengo uwu ndi muyeso wa kuchuluka kwa maunyolo a polima mu zitsanzo.
3. Katundu Wathupi:
   • Maonekedwe enieni a cellulose hydroxyethyl ether, monga kusungunuka, kukhuthala, ndi kuthekera kopanga gel, zimadalira zinthu monga kuchuluka kwa m'malo (DS) ndi kulemera kwa maselo. Maselo apamwamba a mamolekyu amatha kukhudza kukhuthala kwa ma viscosity ndi machitidwe a rheological a mayankho.
4. Kusungunuka:
   • Cellulose hydroxyethyl ether nthawi zambiri amasungunuka m'madzi. Mlingo wa m'malo ndi maselo kulemera zingakhudze ake solubility ndi ndende imene imapanga zomveka zothetsera.
5. Mapulogalamu:
   • Cellulose hydroxyethyl ether yokhala ndi molekyulu yolemera 1,000,000 imatha kupeza ntchito m'mafakitale osiyanasiyana:
     • Mankhwala: Atha kugwiritsidwa ntchito popanga mankhwala opangidwa molamulidwa, zokutira, ndi zina zamankhwala.
     • Zida Zomangira: Mumatope, pulasitala, ndi zomatira matailosi kuti madzi asasungike bwino komanso kuti azigwira ntchito bwino.
     • Zopaka ndi Mafilimu: Popanga zokutira ndi mafilimu chifukwa cha mawonekedwe ake opanga mafilimu.
     • Zopangira Zosamalira Munthu: Mu zodzoladzola ndi zinthu zosamalira munthu chifukwa chakukula kwake komanso kukhazikika kwake.
6. Kuwongolera kwa Rheological:
   • Kuwonjezera pa cellulose hydroxyethyl ether angapereke ulamuliro pa rheological katundu wa mayankho, kupanga kukhala ofunika mu formulations kumene kulamulira mamasukidwe akayendedwe n'kofunika.
7. Biodegradability:
   • Ma cellulose ether, kuphatikiza zotuluka mu hydroxyethyl ether, nthawi zambiri zimatha kuwonongeka, zomwe zimapangitsa kuti asamawononge chilengedwe.
8. Kaphatikizidwe:
   • The synthesis kumakhudza mmene mapadi ndi ethylene okusayidi pamaso pa zamchere. Mlingo wa m'malo ndi maselo kulemera akhoza lizilamulira pa kaphatikizidwe ndondomeko.
9. Kafukufuku ndi Chitukuko:
   • Ofufuza ndi opangira amatha kusankha ma cellulose hydroxyethyl ethers kutengera kulemera kwa maselo ndi kuchuluka kwa m'malo kuti akwaniritse zomwe akufuna pazogwiritsa ntchito zosiyanasiyana.

Ndikofunikira kudziwa kuti katundu ndi ntchito za cellulose hydroxyethyl ether zimatha kusiyanasiyana kutengera mawonekedwe ake, ndipo zomwe zatchulidwazi zimapereka chithunzithunzi chonse. Tsatanetsatane waukadaulo woperekedwa ndi opanga kapena ogulitsa ndikofunikira kuti mumvetsetse mtundu wa cellulose hydroxyethyl ether womwe ukufunsidwa.
