Cellulose ether
Ma cellulose ethers ndi gulu la zotumphukira za cellulose zosinthidwa, pomwe magulu a hydroxyl (-OH) a mamolekyu a cellulose amasinthidwa ndi magulu a ether (-OR). Zosinthazi zimakulitsa mphamvu ya cellulose, ndikupangitsa kuti ikhale yothandiza m'mafakitale osiyanasiyana.
Ma cellulose Ether atsimikizira kuti ndi othandiza kwambiri ma polima achilengedwe, kupeza ntchito m'malo ophatikiza chakudya, zinthu zosamalira anthu, mankhwala opangira mafuta, zomangamanga, mapepala, zomatira, ndi nsalu.;
Amakhala ndi phindu lapadera pakugwiritsa ntchito mankhwala chifukwa cha mawonekedwe omwe amaphatikiza kutentha kwa magalasi apamwamba, kukhazikika kwamankhwala ndi photochemical, kusungunuka, crystallinity yochepa, kuthekera kwa hydrogen bonding, ndi kawopsedwe kakang'ono.;
Pankhani ya kawopsedwe, ma cellulose ethers alibe mphamvu zolowera m'matumbo am'mimba ndipo ambiri ali kale m'mapangidwe ovomerezeka ndi US Food and Drug Administration.
Ma cellulose ethers ndi ma polima osungunuka m'madzi opangidwa ndi kusintha kwa mankhwala a cellulose.;
Ma cellulose ethers akuluakulu amalonda amaphatikizapo carboxymethylcellulose (CMC), methylcellulose (MC) ndi zotumphukira monga hydroxypropyl methylcellulose (HPMC) ndi hydroxyethyl methylcellulose (HEMC), hydroxyethylcellulose (HEC) ndi zotumphukira monga ethyl hydroxyethylHEcellulose (methylEmethylEthyylHEcellulose) ), hydroxypropyl cellulose (HPC), ndi ethylcellulose (EC).
Ma cellulose ethersamagwira ntchito ngati zolimbitsa thupi, zonenepa, komanso zosintha ma viscosity m'mafakitale ambiri, kuphatikiza chakudya, mankhwala, zinthu zosamalira anthu, mankhwala opangira mafuta, zomangamanga, mapepala, zomatira, ndi nsalu;
Posankha ntchito, amapikisana wina ndi mzake komanso ndi ma polima osungunuka m'madzi (polyvinyl mowa, polyurethane associative thickeners, polyacrylates) ndi ma polima osungunuka m'madzi (xanthan chingamu, carrageenan, dzombe chingamu).
Kusankhidwa kwa polima kumatsimikiziridwa ndi kusinthanitsa kwamitengo/ntchito, kupezeka, komanso kumasuka kwakusintha kwazinthu potengera mtengo/machitidwe.
Ma cellulose ether ndi ufa wa cellulose etha wopangidwa ndi ulusi wamatabwa kapena woyengedwa wamfupi wa thonje monga zida zazikulu, pambuyo pa mankhwala opangira mankhwala komanso zochita za etherifying monga chlorinated ethylene, chlorinated propylene ndi ethylene oxidized.
Kapangidwe ka cellulose ether ndizovuta.;
Cellulose ether imayamba ndi kutulutsa mapadi kuchokera ku thonje kapena nkhuni, zomwe zimasandulika kukhala zamchere zamchere pambuyo powonjezera sodium hydroxide ndi mankhwala amachitira (alkaline solution).
Pansi pa zochita za etherifying agents (etherification reaction), ma cellulose ether amapangidwa kuchokera ku cellulose yamchere kudzera munjira monga kutsuka ndi madzi, kuyanika ndi kupera.
Ma cellulose ethers ndiwowonjezera ofunikira kwambiri pazowonjezera zamakono zopangira simenti ndi gypsum.;
Cellulose ether imathandizira kupanga mapangidwe, imapangitsa machinability, imawonjezera kutulutsa, kuphimba ndi kuchepetsa zinyalala.
Ma cellulose ether amapereka zabwino zambiri panthawi imodzi; Zimatengera ntchito monga kusungira madzi, kudzoza, kuwonjezereka kwa ming'alu, anti-slip, kuwonjezera kumamatira ndikuwonjezera nthawi yotseguka.;
Cellulose ether imagwira ntchito ndi malingaliro ochita upainiya, kuwongolera kokhazikika, kasamalidwe ndi ntchito yamakasitomala oyamba mu R&D.
Ma cellulose ethers ndi oyeretsedwa kwambiri, osungunuka m'madzi, ma polima osakhala a ionic opangidwa kuti agwiritsidwe ntchito ngati zothandizira kusunga madzi, kukhuthala ndi kupanga mafilimu, ma colloids oteteza, kuyimitsa ndi emulsifying agents, binders ndi stabilizers.
Kuchokera ku cellulose, gwero lachilengedwe, lochuluka komanso longowonjezedwanso, Ma cellulose ethers akhala akugwiritsidwa ntchito kwa zaka zopitilira 50 kupititsa patsogolo ntchito yazinthu pakusamalira munthu, mankhwala ndi zakudya.
