Crystallization iyo Astaamaha Semi-Aromatic Copolymer Nylon/PA66

Hello, kaalay inaad la tashato alaabtayada!

Si loo barto habdhaqanka crystallization iyo sifooyinka PA66 oo lagu beddelay noocyo kala duwan oo ah xabagta nayloon ee semi-aromatic copolymerized, noocyo kala duwan oo semi-aromatic copolymerized nylon resin ayaa lagu daray saamaynta noocyada kala duwan iyo waxa ku jira ee semi-caraf udgoon. Xabagta nayloon ee koobiyeysan oo ku saabsan dabeecadda crystallization iyo sifooyinka walxaha alwaaxyada ayaa la darsay.Natiijooyinku waxay muujinayaan in noocyada kala duwan ee udugga semi-aromatic copolymerized nylon ay leeyihiin dabeecad crystallization oo kala duwan iyo content ugu fiican ee isku darka ah.Iyada oo korodhka ka kooban poly-m-xylyleneadipamide (MXD6), heerkulka dhalaalka (T)miyo heerkulka crystallization (Tc) ee isku dhafka ah ayaa hoos u dhacaya, qallafsanaanta iyo kuleylka kuleylka ee isku-dhafka ayaa kordha, adkaanta mc iyo nuugista biyaha ayaa hoos u dhacda, cufnaanta ayaa leh saameyn yar.Marka qadarka dheeriga ah ee polyphthalamide (PA6T / 6) uu ka weyn yahay ama la mid yahay 40% ee qaybta resin-ka, dabeecadda crystallization ee isku-darka ayaa bilaaba inay si weyn isu beddesho, qallafsanaanta iyo kulaylka isku-dhafka ayaa la wanaajiyey, iyo adkaanta waa la dhimay.Kordhinta maadada PA6T/6, nuugista biyaha ee isku dhafka ayaa hoos u dhacaya, cufnaanta ayaa leh saameyn yar.Marka tirada lagu daray ee poly (p-phenyl-pentadiamine) (PA5T) ay ka weyn tahay ama la mid tahay 30% ee qaybta resin, PA5T waxay bilaabataa inay door ka ciyaarto isku dhafka, adkaanta waa la dhimay, nuugista biyaha waa la dhimay.Nuugista biyaha ee isku dhafka ayaa marka hore hoos u dhacda ka dibna waxay kordhisaa kororka maadada PA5T, iyo qadarka dheeraadka ah ee PA5T ayaa saameyn yar ku leh cufnaanta isku darka.Marka caddadka polydecamethylene terephthalate (PA10T) ay ka yar tahay 40% qaybta resin, Tm iyo Tc Isku-dhafka ayaa si tartiib tartiib ah u yaraanaya, qallafsanaanta iyo kulaylka mc ee isku-dhafka ayaa la wanaajiyey, adkaantana waa la dhimay.Nuugista biyaha ee isku dhafka ayaa hoos u dhacay kororka maadada PA10T.Marka la kordhiyo ilaa 50% qaybta resin-ka, nuugista biyaha mar dambe lama yarayn, iyo qallafsanaanta kulaylka lama sii wanajin.
