Ethylcellulose barta dhalaalka

Ethylcellulose waa polymer thermoplastic, waxayna jilcisaa halkii ay ku dhalaali lahayd heerkul sare. Ma laha meel dhalaalaysa oo kala duwan sida walxaha crystalline qaarkood. Taa beddelkeeda, waxay maraysaa hab tartiib tartiib ah oo leh heerkul sii kordhaya.

Jilcinta ama heerkulka kala-guurka dhalada (Tg) ee ethylcellulose wuxuu caadi ahaan ku dhacaa meel kala duwan halkii uu ka ahaan lahaa meel gaar ah. Kala duwanaanshaha heerkulkani wuxuu ku xiran yahay arrimo ay ka mid yihiin heerka beddelka ethoxy, miisaanka unugyada, iyo qaabaynta gaarka ah.

Guud ahaan, heerkulka kala-guurka dhalada ee ethylcellulose wuxuu ku jiraa inta u dhaxaysa 135 ilaa 155 darajo Celsius (275 ilaa 311 darajo Fahrenheit). Kala duwanaanshahan ayaa tilmaamaya heerkulka ethylcellulose uu noqdo mid dabacsan oo ka sii adag, kana soo wareegaya muraayad ilaa xaalad caag ah.

Waxaa muhiim ah in la ogaado in dabeecadda jilicsan ee ethylcellulose ay kala duwanaan karto iyadoo ku saleysan codsigeeda iyo joogitaanka maaddooyinka kale ee qaabeynta. Macluumaad gaar ah oo ku saabsan sheyga ethylcellulose ee aad isticmaalayso, waxa lagu talinayaa in aad tixraacdo xogta farsamada ee ay bixisay soo saaraha Ethyl cellulose.
