Ethyl cellulose (EC)
Mafotokozedwe Akatundu
Ethylel® ethyl cellulose (EC) ndi yopanda tanthauzo, yoyera mpaka ufa wonyezimira wa tan.thyl. Amagwiritsidwa ntchito mu ma gels a Suntan, mafuta, ndi mafuta odzola. Uwu ndi ethyl ether of cellulose.thyll cellulose ec amasungunuka m'malo osiyanasiyana okhazikika. Nthawi zambiri, ethyl cellulose ec imagwiritsidwa ntchito ngati chinthu chosasinthika, chopanda zowonjezera mu matrix kapena ziwonetsero.
Ethyl cellulose ec imatha kugwiritsidwa ntchito kutsuka zosakaniza zingapo kapena zingapo za piritsi kuti ziwachitire ndi zinthu zina kapena wina ndi mnzake. Imatha kupewa kusinthasintha kwa zinthu za maxidic mosavuta monga ascorbic acid, kulola mapiritsi a mapiritsi ena osakanikirana. Kuwala kwa micro-tinthu tating'ono, ma pellets ndi mapiritsi.
Divancel® ethyl cellulose sangasungunuke m'madzi, koma osungunuka ambiri oyipitsidwa, kotero EC imagwiritsidwa ntchito m'mapiritsi, magaleta a wothandizira wake. Itha kuwonjezera kuuma kwa mapiritsi kuti muchepetse mapiritsi am'madzi kuti apangitse mawonekedwe a mafilimu kuti awonetsere mapiritsi, kuti mupewe kulephera kwa mankhwala osokoneza bongo kuti atetezetse mankhwala osokoneza bongo a Metamorphic, Kusungidwa koyenera kwa mapiritsi, kuyenera kugwiritsidwa ntchito ngati zinthu zolimbikitsa za mapiritsi otulutsidwa.

EC itha kusungunuka m'malo osiyanasiyana okhazikika, zosungunulira wamba (kuchuluka kwa voliyumu):
1) toloene: ethanol = 4: 1
2) Ethanol
3) acetone: isoppanol = 65:35
4) Toliene: Isoppanol = 4: 1
Methyl Acetate: Methanol = 85:15

Mapulogalamu
Ethyl cellulose ndi utoto wambiri. Imagwira ntchito ngati bander, chibwibwi, rheology yosintha, kanema wakale, ndi chotchinga madzi pazomwe zimagwiritsidwa ntchito pansipa:
Kumatira: Ethyl cellulose imagwiritsidwa ntchito kwambiri mu otentha masults ndi zomatira zina zosungunulira chifukwa cha kutentha kwake kopambana komanso nyonga zake. Imasungunuka m'makalasi otentha, mapiritsi, ndi mafuta.
Zovala: ethyl cellulose imapereka madzi osautsa, kulimba mtima, kusinthasintha komanso kupindika kwakukulu kwa utoto ndi zokutira. Itha kugwiritsidwanso ntchito m'mapepala ena apadera monga m'mapepala olumikizana ndi chakudya, kuyatsa kwabwino, kufota, kungokongoletsa, mapira, zokutira zam'madzi.
Ceramic: ethyl cellulose ikugwiritsidwa ntchito kwambiri mu ceramic yomwe imapangidwira pamagetsi ogwiritsira ntchito ma cardictic alractic. Imagwira ntchito ngati binder ndi rheology olera. Imaperekanso mphamvu zobiriwira ndikuwotcha popanda zotsalira.
Kusindikiza Inks: Ethyl cellulose imagwiritsidwa ntchito mu makilogalamu osungunuka osungunuka monga mafuta odzola, kusinthasintha ma inks osindikizira. Ndi chilengedwe komanso chogwirizana kwambiri ndi mafayilo ndi ma polima. Imapereka chizolowezi chambiri komanso zomangira zomwe zimathandiza kupanga mphamvu yayikulu ndi mafilimu otsutsana.
