Ethyl Cellulose(EC)
Tlhaloso ea Sehlahisoa
Ethyl Cellulose (EC) ke phofshoana e sa latsoeheng, e phallang ka bolokolohi, e tšoeu ho isa ho e khanyang ea tan-colored.ethyl cellulose ke setlamo, sa pele sa filimi, le se teteaneng.E sebelisoa ho etsa li-gel, litlolo le litlolo tsa letsatsi.Ena ke ether ea ethyl ea cellulose.Ethyl Cellulose EC e qhibiliha ka har'a mefuta e mengata ea metsoako ea tlhaho.Ka tloaelo, Ethyl Cellulose EC e sebelisoa e le karolo e sa tsitsang, e sa tsitsang ka har'a matrix kapa litsamaiso tsa ho roala.
Ethyl Cellulose EC e ka sebelisoa ho koahela motsoako o le mong kapa tse ling tse sebetsang tsa letlapa ho li thibela ho sebetsana le lisebelisoa tse ling kapa le tse ling.E ka thibela ho fifala ha lintho tse nang le oxidizable habonolo joalo ka asiti ea ascorbic, e lumellang granulations bakeng sa matlapa a hatelletsoeng habonolo le mefuta e meng ea litekanyetso.EC e ka sebelisoa ka boyona kapa hammoho le likarolo tse qhibilihang ka metsing ho lokisa liphahlo tse tsitsitseng tsa filimi tse sebelisoang khafetsa. ho koaheloa ha li-micro-particles, li-pellets le matlapa.
Ethyl cellulose ha e khone ho qhibiliha ka metsing, empa e qhibiliha ka har'a metsoako e mengata ea lintho tse phelang, kahoo EC e sebelisoa matlapeng, li-granules tsa sekhomaretsi sa eona.E ka eketsa boima ba matlapa ho fokotsa matlapa a friability, e ka sebelisoa e le moemeli oa ho etsa lifilimi ho ntlafatsa ponahalo ea matlapa, tatso e ikhethileng, ho qoba ho hloleha ha lithethefatsi tse thibelang metsi ho thibela ho ata ha mahlahana a phetoho ea metamorphic, ho khothaletsa. polokelo e bolokehileng ea matlapa, le eona e ka sebelisoa e le lisebelisoa tse matlafatsang bakeng sa matlapa a tsoelang pele a tokollo.

Lisebelisoa
Ethyl Cellulose ke resin e nang le mesebetsi e mengata.E sebetsa joalo ka binder, thickener, rheology modifier, filimi ea pele, le thibelo ea metsi lits'ebetsong tse ngata tse hlalositsoeng ka tlase:
Likhomaretsi: Ethyl Cellulose e sebelisoa ka ho pharaletseng ho qhibiliha ho chesang le li-adhesives tse ling tse thehiloeng ho solvent bakeng sa thermoplasticity e ntle haholo le matla a eona a matala.E qhibiliha ka har'a li-polymer tse chesang, li-plasticizers le oli.
Liaparo: Ethyl Cellulose e fana ka ho thibela metsi, ho tiea, ho feto-fetoha ha maemo le ho khanya ho phahameng ho lipente le liphahlo.E ka boela ea sebelisoa liphahlong tse ling tse khethehileng tse kang pampiring ea lijo, mabone a fluorescent, marulelo, enameling, lacquers, li-varnish le liphahlo tsa marine.
Ceramics: Ethyl Cellulose e sebelisoa haholo ka lirafshoa tse entsoeng bakeng sa lisebelisoa tsa elektroniki tse kang li-multi-layer ceramic capacitor.E sebetsa joalo ka setlamo le rheology modifier.E boetse e fana ka matla a botala le ho chesa ntle le masala.
Li-Inks tsa Khatiso: Ethyl Cellulose e sebelisoa mekhoeng ea enke e thehiloeng ho solvent e kang gravure, flexographic le li-inks tsa khatiso tsa skrine.E na le organosoluble ebile e lumellana haholo le li-plasticizers le li-polymers.E fana ka thepa e ntlafetseng ea rheology le e tlamang e thusang ho thehoa ha lifilimi tse matla le tse hanyetsang.
