Celluluse etherch

Cellulose Ether Ether ndi polymer pompopomphukira kwa cellulose ndi mawonekedwe a ether. Mphete iliyonse ya glucose mu cellulose macromolecule imakhala ndi gulu la hydroxyl pa atomu wachisanu ndi chimodzi, ndipo yachiwiri hydroxyl ma atomu achiwiri ndi achitatu. The hydrojeni mu gulu la hydroxyl amasinthidwa ndi gulu la hydrocarbon kuti apange cellose. Ndiwopanga mankhwala a hydroxyl hydrogen ndi gulu la hydrocarbon mu cellulose polymer. Cellulose ndi polymerroxy polymer poimba kuti sisungunuke kapena kusungunuka. Cellulose imatha kusungunuka m'madzi, kuchepetsa alkali yankho ndi zosungunulira pambuyo pa kusinthika, ndipo ali ndi thermoplacastic.

Cellulose ether ndi nthawi yayitali ya mndandanda wazinthu zingapo zomwe zimapangidwa ndi alkali cellulose ndikumukonda. Ma cellulose alkali alowa m'malo mwa othandizira osiyanasiyana kuti apeze cellulose yosiyanasiyana.

Malinga ndi ma ionization chinthu chamitundu, celloseses ceres zitha kugawidwa mu Ionic (monga Carboxymethyl cellulose) madera awiri.

Malinga ndi mtundu wa gawo la malo oyimira m'malo a celluse agawika mu ether imodzi (monga methyl cellulose) ndi ethersed ethelose (monga hydroxypropyl celyiluse). Malinga ndi kusungunuka, imatha kugawidwa m'madzi (monga hydroxethyl cellulose) ndi solvent soluluse (monga ethyl cellulose). Matoma owuma makamaka amagwiritsa ntchito ma cellulose osungunuka madzi, omwe amatha kugawidwa mu mtundu wosungunuka mwachangu ndikuchedwa kusungunuka pambuyo pa chithandizo chapamwamba.

Admixtaxures amatenga gawo lalikulu pakuwongolera matope owuma ndi akaunti yoposa 40% yazomwe zimawononga matope osakanikirana. Gawo lalitali pamsika wapabanja limaperekedwa ndi opanga zakunja, ndipo kuchuluka kwa malonda kumaperekedwanso ndi othandizira. Zotsatira zake, mtengo wa zinthu zosakanizika matope umakhala wokwera, ndipo nkovuta kuchitira matope wamba owoneka bwino ndikuyala matope ndi malo ambiri komanso ambiri. Zogulitsa pamsika waukulu zimayendetsedwa ndi makampani akunja, opanga matope otsika phindu, ndalama zochepa; Kugwiritsa ntchito kaphatikizidwe kamakhala kosakanikirana komanso kuwunikira, kutsata mwakhungu.

Wogwira ntchito yosungidwa yamadzi ndiye njira yofunika kwambiri yosinthira matope osakanikirana owuma komanso imodzi mwazovomerezeka kuti mudziwe mtengo wamatope osakanikirana. Ntchito yayikulu ya ethel ether ndikusunga madzi.

Njira yamakina am'matope mwa matope ndi motere:
