Intangiriro ya polyamide pa6
Polyamide, yitwa polyamide pa mugufi, izwi nka nylon.Nubwoko bwa kristaline ya termoplastique ya plastike ikorwa na polymerisation ya binary amine na diacid cyangwa lactam.Hariho ubwoko bwinshi bwa PA, ukurikije umubare wa atome ya karubone muri monomer igira uruhare muri reaction ya polymerisation, kandi ubwoko butandukanye bwa PA hamwe nibikorwa bitandukanye burashobora gushingwa, nka PA6, PA66, PA612, PA1010, PA11, PA12, PA46 , PA9, PA1212, nibindi PA6 na PA66 bikoreshwa cyane, bingana na 90% yumusaruro wose.
Ibintu rusange bya polyamide pa6
Polyamid pa6 ifite polarite, idafite uburozi, uburyohe kandi byoroshye kurangi; ubwoko bwa Crystalline (50 kugeza 60%), amata yera yera cyangwa yera yumuhondo yumuhondo; igipimo cyumuvuduko); Ubucucike: 1.02 kugeza kuri 1,20g / cm³; Kwinjiza amazi menshi, hydrolysis reaction izaba kuri dogere selisiyusi 230; kwinjiza amazi PA46> PA6> PA66> PA1010> PA11> PA12> PA1212; Igipimo kinini cyo kugabanuka.PP, PE> PA> PS, ABS.Hagati yinzitizi yumutungo hamwe ninzitizi ikomeye kumuyaga.
Imiterere yubukorikori bwa polyamide pa6
Imiterere yubukorikori bwa polyamide pa6 muri rusange ifitanye isano na kristu: Iyo hejuru ya kristu, niko imbaraga nizindi zikomeye.Kubijyanye nimbaraga, PC> PA66> PA6> POM> ABS.Imbaraga zigira ingaruka cyane kuri hygroscopicity, uko ubushyuhe buri hejuru, niko hygroscopique iba iri hejuru, niko imbaraga za tensile zigabanuka nibindi bintu.
Ingaruka gukomera bigira ingaruka cyane kubikorwa bya hygroscopique.Hamwe n'ubwiyongere bw'ubushyuhe, kwinjiza amazi biriyongera kandi ubukana buriyongera..
Polyamid pa6 ifite amavuta meza yo kwinezeza no kurwanya kwambara neza.
Kurwanya amavuta meza, urugero.lisansi.
Imbaraga z'umunaniro ni nyinshi, muri rusange 20% kugeza 30% byimbaraga za tensile.Imbaraga z'umunaniro wa PA6 na PA66 zishobora kugera kuri 22MPa, zikurikira POM (35MPa) kandi hejuru ya PC (10-14MPa).Urukurikirane ukurikije imbaraga z'umunaniro: POM> PBT, PET> PA66> PA6> PC> PSF> PP.
Gukomera cyane, PA66: 108 kugeza 120HRR;PA6120HRR.
Kurwanya Creep Kurwanya: Kuruta PP na PE, kandi biruta ABS na POM.
Kurwanya imihangayiko idahwitse: Kuvura Annealing cyangwa ubushuhe bigomba gukorwa nyuma yo gutunganya ibicuruzwa.
