Calaamadaha wax soo saarka

Polyphthalthamide (aka. PAS, POLYOMIde-ka Sare ee Polyamide) waa qayb ka mid ah enemoplastic-ka the polmontlastic-ka ah ee polyont (NYLON) ee loo yaqaan '55% ama in ka badan oo ka mid ah qaybta' CardBylic Acid 'ee ka mid ah silsiladda polymer-ka ayaa ka kooban isku darka of trehaphalic (TPA) iyo asiidhyada isqarxinta (IPA). Beddelka alifacatic gorgol-ka-gobakaallada udgoon ee laf-dhabarka polymer wuxuu kordhiyaa meesha dhalaalaysa, heerkulka kala-guurka ee galaaska, iska caabinta kiimikada iyo adkaanta kiimikada iyo adkaanta.

Bixinta PPA ee ku saleysan PPA ayaa loo geystaa qaybo lagu beddelo macdanta codsiyada u baahan caabbinta heerkulka sare sida qaybaha tareenka tamarta ee heerkulka ah, guryaha isku xirka heerkulka korantada ee heerkulka korantada iyo adeegsiyo badan oo badan.

Heerkulka kala-guurka ee ku meelgaarka ah ee PPA ayaa kordhaysa inta qaddarka TPA ay kordhaan. Haddii in ka badan 55% qaybta acid ee PPA laga gaaro IPA, markaa copolmymer waa amorphous. Sifooyinka ku saabsan polylols polylols v polyplous v bushmoodka amorphous waxaa lagu sharaxay meel kale si faahfaahsan. Si kooban, Crystallineline waxay ka caawisaa iska caabbinta kiimikada iyo guryaha farsamada ee ka sarreeya heerkulka kala-guurka quraaradda (laakiin ka hooseysa meesha dhalaalaysa). Polyporter-ka am lymous wuxuu ku fiican yahay warshadda iyo daah furnaanta.

PPA-ga PPA

Qalabka PPA PPA waxay leedahay guryo isku-dhafan oo heer sare ah, oo si fiican u sameeya kuleylka, korantada, jirka iyo kiimikada. Gaar ahaan heerkulka sare ee PPA wali waxay leedahay feejignaan sare iyo xoog sare, oo ay weheliso saxsanaanta cabirka cabirka iyo xasillooni ee aad u wanaagsan.
