Ethyl Cellulose(EC)
Fa'amatalaga o oloa
O le Ethyl Cellulose (EC) o se mea e leai se tofo, tafe fua, pa'epa'e e pa'epa'e lanu pa'epa'e. Ethyl cellulose o se mea fa'apipi'i, fa'amu ata, ma mafiafia. E fa'aaogaina i gels suntan, kulimi, ma lotions. O le ethyl ether lea o le cellulose.Ethyl Cellulose EC e soluble i le tele o vailaʻau faʻalaʻau. E masani lava, o le Ethyl Cellulose EC o loʻo faʻaaogaina e avea o se mea e le mafai ona fulafula, e le mafai ona faʻaaogaina i le matrix poʻo le faʻapipiʻiina.
E mafai ona fa'aogaina le Ethyl Cellulose EC e fa'aofuina ai se tasi po'o le sili atu o mea aoga o le laulau e puipuia ai mai le fa'afeagai ma isi mea po'o le tasi ma le isi. E mafai ona puipuia ai le fa'alilolilo o mea e faigofie ona fa'afefeteina e pei o le ascorbic acid, fa'atagaina granulations mo papamaa faigofie fa'apipi'i ma isi fomu su'ega. E mafai ona fa'aogaina le EC na'o ia po'o le fa'atasi ma vaega e mafai ona solu vai e saunia ai fa'alavalava fa'asa'o fa'amalologa e masani ona fa'aaoga mo le ufiufi o micro-particles, pellets ma papa.
E le mafai e le Ethyl cellulose ona solo i totonu o le vai, ae mafai ona solu i le tele o solvents organic, o lea e faʻaaogaina ai le EC i papamaʻa, granule o lona sui faʻapipiʻi. E mafai ona faʻateleina le maʻaʻa o papa e faʻaitiitia ai le pala, e mafai ona faʻaaogaina e fai ma sui e fai ata tifaga e faʻaleleia ai foliga vaaia o papa, tofo vavae ese, e aloese ai mai le toilalo o vailaʻau faʻafefe vai e puipuia ai le ulufale mai o sui suiga metamorphic, faʻalauiloaina le teuina saogalemu o papamaa, e mafai foi ona faʻaaogaina e avea ma mea faʻamalosia mo papa faʻamalolo tumau.

Talosaga
Ethyl Cellulose o le resini tele-galuega. E galue e pei o se fusifusia, mafiafia, rheology modifier, ata tifaga muamua, ma vai pa i le tele o talosaga e pei ona auiliiliina i lalo:
Adhesives: Ethyl Cellulose o loʻo faʻaaogaina lautele i mea vevela vevela ma isi mea faʻapipiʻi faʻapipiʻi mo lona sili atu le thermoplasticity ma le malosi lanu meamata. E solu i polymers vevela, plasticizers, ma suauu.
Pa'u: Ethyl Cellulose e maua ai le susu, ma'a'a, fetu'una'i ma iila maualuga i vali ma fa'alavalava. E mafai fo'i ona fa'aoga i nisi o fa'alava fa'apitoa e pei o pepa fa'afeso'ota'i mea'ai, moli fa'amalama, fa'aulufale, fa'amalama, lacquers, varnishes, ma fa'alava o le gataifale.
Ceramics: Ethyl Cellulose e faʻaaogaina tele i sima e faia mo mea faʻaeletoroni e pei o le tele-layer ceramic capacitors. E galue e pei o se fusifusia ma le rheology modifier. E maua ai foi le malosi lanu meamata ma mu e aunoa ma se toega.
Lomitusi Inisi: Ethyl Cellulose o loʻo faʻaaogaina i faiga vaitusi faʻavae solvent e pei ole gravure, flexographic ma lau lomitusi lautusi. E organosoluble ma sili ona fetaui ma plasticizers ma polymers. E maua ai le faʻaleleia atili o le rheology ma mea faʻapipiʻi e fesoasoani i le faʻavaeina o ata tifaga malosi ma tetee.
