Ukuqaliswa kwe-polyamid pa6
I-Polyamide, ekubhekiselwa kuyo njenge-polyamide pa ngokufutshane, yaziwa ngokuba yinayiloni.Luhlobo lweplastiki ye-crystalline ye-thermoplastic eyenziwe yi-polymerization ye-binary amines kunye ne-diacid okanye i-lactam.Kukho iintlobo ezininzi ze-PA, ngokwenani le-athom zekhabhoni kwi-monomer ebandakanyekayo kwi-polymerization reaction, kunye neentlobo ezahlukeneyo ze-PA ezineentsebenzo ezahlukeneyo zinokuqulunqwa, njenge-PA6, i-PA66, i-PA612, i-PA1010, i-PA11, i-PA12, i-PA46 , PA9, PA1212, njl. I-PA6 kunye ne-PA66 zisetyenziswa kakhulu, zibala i-90% yemveliso epheleleyo.
Iimpawu eziqhelekileyo zepolyamid pa6
I-Polyamid pa6 ine-polarity, engeyotyhefu, ayinancasa kwaye kulula ukuyibala;Uhlobo lweCrystalline (50 ukuya kwi-60%), igranule emhlophe ekhanyayo okanye etyheli; ulwelo lweNewtonian (ulwelo lweNewtonian lubhekisa kulwelo apho uxinzelelo lulingana izinga loxinzelelo);Uxinzelelo: 1.02 ukuya ku-1.20g/cm³;Ukufunxa amanzi aphezulu, ukusabela kwehydrolysis kuya kwenzeka kuma-230 degrees Celsius;Ukufunxa amanzi PA46 > PA6 > PA66 > PA1010 > PA11 > PA12 > PA1212;Isantya esikhulu sokushwabana sokubumba.PP, PE > PA > PS, ABS.Ipropathi yesithintelo esiphakathi kunye nesithintelo esinamandla emoyeni.
Iipropati zomatshini we-polyamid pa6
Iimpawu zomatshini we-polyamid pa6 ngokubanzi zihambelana ne-crystallinity: I-crystallinity ephezulu, iphezulu amandla kunye nokuqina kokuqina.Ngokubhekiselele kumandla, i-PC> PA66> PA6> POM> ABS.Amandla achaphazeleka kakhulu yi-hygroscopicity, iqondo lokushisa eliphezulu, i-hygroscopicity ephezulu, i-hygroscopicity iphantsi, amandla aphantsi kunye nezinye iimpawu.
Ukuqina kwempembelelo kuchaphazeleka kakhulu ngumsebenzi we-hygroscopic.Ngokunyuka kweqondo lokushisa, ukunyuswa kwamanzi kwanda kwaye ukuqina kwanda.(Ngesiqhelo, ukuqina akuhambi kakuhle kwindawo eyomileyo kunye nobushushu obuphantsi, kwaye kunokwenzeka ukuba ubenoxinzelelo lokuqhekeka ngeemveliso zentsimbi kunye nokwaphuka kwentsimbi ku-0℃.
I-Polyamid pa6 ine-self-lubricity elungileyo kunye nokumelana kakuhle nokunxiba.
Ukuchasana okugqwesileyo kwioli, umz.ipetroli.
Amandla okudinwa aphezulu, ngokubanzi ama-20% ukuya kwi-30% yamandla okuqina.Amandla okukhathala kwe-PA6 kunye ne-PA66 anokufikelela malunga ne-22MPa, okwesibini kuphela kwi-POM (35MPa) kwaye iphezulu kune-PC (10-14MPa).Ukulandelelana ngokwamandla okukhathala: POM> PBT, PET> PA66> PA6> PC> PSF> PP.
Ubunzima obuphezulu, i-PA66: 108 ukuya kwi-120HRR;PA6120HRR.
Ukuxhatshazwa kwe-Creep embi: Kungcono kune-PP kunye ne-PE, kwaye kubi kune-ABS kunye ne-POM.
Ukumelana noxinzelelo olubi lokuqhekeka: Ukufakelwa okanye unyango lokufumisa kufuneka lwenziwe emva kokulungiswa kweemveliso.
