Kodi pali kusiyana kotani pakati pa cellulose ether ndi cellulose?

Ma cellulose ndi cellulose ether onse amachokera ku cellulose, polima zachilengedwe zomwe zimapezeka m'makoma a cellulose.Komabe, ali ndi kusiyana kosiyana m'mapangidwe awo amankhwala ndi katundu:

1. Kapangidwe ka Mankhwala: Ma cellulose ndi mzere wa polysaccharide wokhala ndi mayunitsi obwerezabwereza olumikizidwa ndi β(1→4) glycosidic bond.Ndi polymer yowongoka yokhala ndi digiri yapamwamba ya crystallinity.
2. Hydrophilicity: Ma cellulose ndi hydrophilic, kutanthauza kuti ali ndi mgwirizano wamphamvu wamadzi ndipo amatha kuyamwa chinyezi chambiri.Katunduyu amakhudza machitidwe ake pazinthu zosiyanasiyana, kuphatikiza kuyanjana kwake ndi machitidwe opangira madzi monga zosakaniza za simenti.
3. Kusungunuka: Pure cellulose sasungunuke m'madzi ndi zosungunulira zambiri za organic chifukwa cha mawonekedwe ake owala kwambiri komanso kulumikizana kwakukulu kwa haidrojeni pakati pa maunyolo a polima.
4. Kutulutsa: Cellulose ether ndi mtundu wosinthidwa wa cellulose womwe umapezeka kudzera muzotulutsa mankhwala.Izi zimaphatikizapo kuyambitsa magulu ogwira ntchito, monga hydroxyethyl, hydroxypropyl, methyl, kapena carboxymethyl magulu, pamsana wa cellulose.Zosinthazi zimasintha mawonekedwe a cellulose, kuphatikiza kusungunuka kwake, machitidwe a rheological, komanso kugwirizana ndi zinthu zina.
5. Kusungunuka m'madzi: Ma cellulose ethers amatha kusungunuka kapena kutayika m'madzi, kutengera mtundu wake komanso kuchuluka kwa m'malo.Kusungunuka kumeneku kumawapangitsa kukhala othandiza kwambiri m'mafakitale osiyanasiyana, kuphatikiza mankhwala, chakudya, zodzoladzola, ndi zomangamanga.
6. Kugwiritsa ntchito: Ma cellulose ethers amapeza kuti amagwiritsidwa ntchito ponseponse ngati zowonjezera, zolimbitsa thupi, zomangira, ndi zopangira mafilimu muzinthu zosiyanasiyana.Pomanga, nthawi zambiri amagwiritsidwa ntchito ngati zowonjezera muzinthu zopangidwa ndi simenti kuti azitha kugwira bwino ntchito, kusunga madzi, kumamatira, ndi zina.

Mwachidule, pamene mapadi ndi mapadi etero amagawana chiyambi wamba, mapadi etere ndi mankhwala kusinthidwa kuti atchule katundu enieni kuti sungunuka kapena dispersible m'madzi ndi oyenera ntchito zosiyanasiyana kumene kulamulira khalidwe rheological ndi mogwirizana ndi zinthu zina amafuna.
