Polyphthalamide (loo yaqaan PPA, Polyamide Performance High) waa qayb ka mid ah resins-ku-samaynta thermoplastic ee qoyska polyamide (nylon) oo lagu qeexay sida marka 55% ama in ka badan oo moles ah qaybta karboxilic acid ee unugga soo noqnoqda ee silsiladda polymer ay ka kooban tahay isku-dar. ee terephthalic (TPA) iyo isophthalic (IPA) acids. Beddelka aliphatic wuxuu go'aamiyaa go'aamada udgoonka ee laf-dhabarka polymer wuxuu kordhiyaa barta dhalaalka, heerkulka kala-guurka dhalada, caabbinta kiimikada iyo qallafsanaanta.
Resins-yada ku salaysan PPA waxa loo qaabeeyey qaybo si ay u bedelaan biraha codsiyada u baahan iska caabin heerkul sare ah sida qaybaha tareenada awooda baabuurta, guryaha isku xidhayaasha korantada ee heerkulka sare iyo isticmaalyo kale oo badan.
Heerkulka kala-guurka dhalada ee PPA wuu kordhaa marka tirada TPA ay korodho. Haddii in ka badan 55% qaybta aysiidhka ee PPA laga sameeyay IPA, markaa koobiyeerka ayaa ah mid aan caadi ahayn. Astaamaha polymers-ka-ka-soo-baxa ah ee polymers-ka amorphous waxaa lagu sifeeyay meelo kale si faahfaahsan. Si kooban, crystalline waxay ka caawisaa caabbinta kiimikada iyo sifooyinka farsamada ee ka sarreeya heerkulka kala-guurka dhalada (laakiin ka hooseeya barta dhalaalka). Amorphous polymers waxay ku fiican yihiin dagaalka iyo hufnaanta.
Tilmaamaha PPA
Maaddada PPA waxay leedahay sifooyin isku-dhafan oo heersare ah, kaas oo si fiican uga shaqeeya kulaylka, korantada, guryaha iyo kiimikooyinka. Gaar ahaan heerkulka sare ee PPA ayaa weli leh qallafsanaan sare iyo xoog sare, oo ay weheliso saxnaanta cabbirka iyo xasilloonida.
Goobta Codsiga ugu Weyn ee PPA
