Crystallization uye Zvivakwa zveSemi-Kunhuhwirira Copolymer Nylon/PA66

Mhoro, huya kuzobvunza zvigadzirwa zvedu!

Kuti udzidze maitiro ekristalllization uye zvimiro zvePA66 zvakagadziridzwa nemhando dzakasiyana dzesemi-inonhuhwirira copolymerized naironi resin, marudzi akasiyana esemi-anonhuhwirira akawedzera nylon resin akawedzerwa kuPA66 resin, uye mhedzisiro yemhando dzakasiyana uye zviri mukati mesemi-anonhuwirira. copolymerized nylon resin pane crystallization maitiro uye zvimiro zvealloy mate- rials zvakadzidzwa.Mhedzisiro yacho inoratidza kuti akasiyana marudzi esemi-anonhuwirira copolymerized nylon resins ane akasiyana crystallization maitiro uye yakakwana yemukati mumisanganiswa.Nekuwedzera kwepoly-m-xylyleneadipamide (MXD6) zvemukati, tembiricha yekunyungudika (Tm) uye tembiricha yecrystallization (Tc) yekuderera kwemusanganiswa, kuoma uye kupisa kwekupisa kwekuwedzera kwemusanganiswa, kuoma kwemc uye kunyura kwemvura kunoderera, uye kuwanda kune zvishoma.Kana huwandu hwekuwedzera hwepolyphthalamide (PA6T/6) hwakakura kupfuura kana kuenzana ne40% yechikamu cheresin, maitiro ekristalllization yemusanganiswa anotanga kushanduka zvakanyanya, kuoma uye kupisa kwekupisa kwemusanganiswa kunowedzerwa, uye kuoma kuri kuita. kuderedzwa.Nekuwedzera kwePA6T / 6 yemukati, kunyura kwemvura yemusanganiswa kunoderera, uye density haina mhedzisiro.Kana iyo yakawedzerwa huwandu hwepoly (p-phenyl-pentadiamine) (PA5T) yakakura kupfuura kana yakaenzana ne30% yechikamu cheresin, PA5T inotanga kuita basa mumusanganiswa, kuoma kunoderedzwa, kunyura kwemvura kunoderedzwa.Kunyura kwemvura yemusanganiswa kunotanga kuderera uyezve kunowedzera nekuwedzera kwePA5T yemukati, uye huwandu hwekuwedzera hwePA5T hune mhedzisiro shoma pakuwanda kwemusanganiswa.Kana huwandu hwe polydecamethylene terephthalate (PA10T) iri pasi pe40% yechikamu che resin, iyo T.m uye Tc yemusanganiswa inodzikira zvishoma nezvishoma, iyo kuomarara uye yekupisa deformation mc yemusanganiswa inowedzerwa, uye kuoma kunoderedzwa.Kunyura kwemvura yemusanganiswa kuderera nekuwedzera kwePA10T yemukati.Kana ichiwedzerwa kusvika ku50% yechikamu che resin, kunyura kwemvura hakuchina kuderedzwa, uye kuomarara uye deformation yekupisa haichagadziriswi.
