Sebaka se qhibilihang sa ethylcellulose

Ethylcellulose ke polymer ea thermoplastic, 'me ea nolofatsa ho fapana le ho qhibiliha ka mocheso o phahameng.Ha e na sebaka se ikhethileng sa ho qhibiliha joalo ka lisebelisoa tse ling tsa kristale.Ho e-na le hoo, butle-butle e nolofala ka mocheso o ntseng o eketseha.

Thempereichara ea ho nolofatsa kapa ea khalase (Tg) ea ethylcellulose hangata e oela ka har'a mefuta e fapaneng ho fapana le ntlha e itseng.Mofuta ona oa mocheso o itšetlehile ka lintlha tse kang tekanyo ea ethoxy substitution, boima ba molek'hule, le mokhoa o itseng oa ho etsoa.

Ka kakaretso, mocheso oa phetoho ea khalase oa ethylcellulose o boemong ba likhato tse 135 ho isa ho tse 155 tsa Celsius (275 ho isa ho 311 degrees Fahrenheit).Lethathamo lena le bontša mocheso oo ethylcellulose e fetohang habonolo le ho se thata, ho tloha ho khalase ho ea sebakeng sa rabara.

Ho bohlokoa ho hlokomela hore boitšoaro bo bonolo ba ethylcellulose bo ka fapana ho latela ts'ebeliso ea eona le boteng ba lisebelisoa tse ling ha ho etsoa.Bakeng sa tlhaiso-leseling e tobileng mabapi le sehlahisoa sa ethylcellulose seo u se sebelisang, ho khothaletsoa ho sheba lintlha tsa tekheniki tse fanoeng ke moetsi oa cellulose ea Ethyl.
