Wahi hoʻoheheʻe ʻo Ethylcellulose

He polymer thermoplastic ka Ethylcellulose, a palupalu ia ma mua o ka heheʻe ʻana i nā mahana kiʻekiʻe. ʻAʻohe ona wahi heheʻe ʻokoʻa e like me kekahi mau mea crystalline. Akā, ke hele nei ia i kahi kaʻina palupalu mālie me ka piʻi ʻana o ka mahana.

ʻO ka mahana palupalu a i ʻole ka mahana hoʻololi aniani (Tg) o ka ethylcellulose e hāʻule pinepine i loko o kahi pae ma mua o kahi kiko kikoʻī. Pili kēia pae mahana i nā mea e like me ke kekelē o ka hoʻololi ʻana o ka ethoxy, ke kaumaha molekala, a me ke ʻano kikoʻī.

Ma keʻano laulā, aia ka mahana hoʻololi aniani o ka ethylcellulose ma ka pae o 135 a 155 degere Celsius (275 a 311 degere Fahrenheit). Hōʻike kēia pae i ka mahana e lilo ai ka ethylcellulose i mea maʻalahi a emi iki ka paʻa, e hoʻololi ana mai kahi aniani a i kahi kūlana rubbery.

He mea nui e hoʻomaopopo he hiki ke ʻokoʻa ke ʻano palupalu o ka ethylcellulose ma muli o kāna noi a me ke alo o nā mea ʻē aʻe i loko o kahi ʻano hana. No ka ʻike kikoʻī e pili ana i ka huahana ethylcellulose āu e hoʻohana nei, ua ʻōlelo ʻia e nānā i ka ʻikepili loea i hāʻawi ʻia e ka mea hana Ethyl cellulose.
