Ethyl Cellulose (EC)
Mafotokozedwe Akatundu
Ethyl Cellulose (EC) ndi yopanda kukoma, yomasuka, yoyera mpaka yopepuka yamtundu wa tan-colored powder.ethyl cellulose ndi binder, filimu yakale, ndi thickener. Amagwiritsidwa ntchito mu suntan gels, creams, ndi lotions. Iyi ndi ethyl ether ya cellulose.Ethyl Cellulose EC imasungunuka mumitundu yambiri ya organic solvents. Nthawi zambiri, Ethyl Cellulose EC imagwiritsidwa ntchito ngati gawo losatupa, losasungunuka m'matrix kapena makina opaka.
Ethyl Cellulose EC itha kugwiritsidwa ntchito kuvala chinthu chimodzi kapena zingapo zogwira ntchito papiritsi kuti zisakhudzidwe ndi zinthu zina kapena wina ndi mnzake. Zitha kulepheretsa kusinthika kwa zinthu zomwe zimatha okosijeni mosavuta monga ascorbic acid, kulola kuti ma granulations a mapiritsi oponderezedwa mosavuta ndi mitundu ina ya mlingo.EC itha kugwiritsidwa ntchito payokha kapena kuphatikiza ndi zigawo zosungunuka m'madzi kukonzekera zokutira zamafilimu zomwe zimagwiritsidwa ntchito pafupipafupi. kuyanika kwa micro-particles, pellets ndi mapiritsi.
Ethyl mapadi sangathe kupasuka m'madzi, koma sungunuka zambiri zosungunulira organic, kotero EC ntchito mapiritsi, granules wa wothandizila ake zomatira. Zitha kuonjezera kuuma kwa mapiritsi kuchepetsa friability mapiritsi, angagwiritsidwe ntchito ngati filimu kupanga wothandizila kusintha maonekedwe a mapiritsi, akutali kukoma, kupewa kulephera madzi tcheru mankhwala kupewa kuchuluka kwa metamorphic kusintha wothandizila, kulimbikitsa. Kusungirako bwino kwa mapiritsi, kumatha kugwiritsidwanso ntchito ngati zida zolimbikitsira mapiritsi omasulidwa nthawi zonse.

Mapulogalamu
Ethyl cellulose ndi utomoni wamitundu yambiri. Zimagwira ntchito ngati binder, thickener, rheology modifier, filimu yakale, ndi chotchinga madzi muzinthu zambiri monga momwe zilili pansipa:
Zomatira: Ethyl Cellulose imagwiritsidwa ntchito kwambiri posungunula ndi zomatira zina zosungunulira chifukwa cha thermoplasticity yake yabwino komanso mphamvu zobiriwira. Amasungunuka mu ma polima otentha, mapulasitiki, ndi mafuta.
Zovala: Ethyl Cellulose imapereka kutsekereza madzi, kulimba, kusinthasintha komanso kuwala kwambiri kwa utoto ndi zokutira. Itha kugwiritsidwanso ntchito pazopaka zapadera monga pamapepala olumikizana ndi chakudya, kuyatsa kwa fulorosenti, denga, zokutira, ma lacquers, vanishi, ndi zokutira zam'madzi.
Ceramics: Ethyl Cellulose imagwiritsidwa ntchito kwambiri muzoumba zopangira zamagetsi monga ma multilayer ceramic capacitors. Zimagwira ntchito ngati binder ndi rheology modifier. Amaperekanso mphamvu zobiriwira ndikuwotcha popanda zotsalira.
Ma Inks Osindikizira: Ethyl Cellulose amagwiritsidwa ntchito m'makina a inki osungunulira monga gravure, flexographic ndi inki zosindikizira pazenera. Ndi organosoluble komanso yogwirizana kwambiri ndi mapulasitiki ndi ma polima. Amapereka ma rheology otsogola komanso zomangira zomwe zimathandizira kupanga mafilimu amphamvu kwambiri komanso kukana.
