Ungahlonza kanjani kahle futhi ukhethe phakathi kwe-PA6 eguquliwe kanye ne-PA66 (Ingxenye 2)?

Iphuzu lesi-5: Ungakhetha Kanjani Phakathi kwe-PA6 ne-PA66?

1. Uma kungadingeki ukumelana nezinga lokushisa eliphezulu ngaphezu kuka-187°C, khetha i-PA6+GF, njengoba kubiza kakhulu futhi kulula ukusetshenzwa.
2. Ngezinhlelo zokusebenza ezidinga ukumelana nezinga lokushisa eliphezulu, sebenzisa i-PA66+GF.
3. I-HDT (Heat Deflection Temperature) ye-PA66+30GF ingu-250°C, kuyilapho leyo ye-PA6+30GF ingu-220°C.

I-PA6 inezindawo zamakhemikhali nezomzimba ezifana ne-PA66, kodwa inendawo encibilikayo ephansi kanye nebanga lokushisa elibanzi lokucubungula. Inikeza ukumelana nomthelela ongcono kanye nokumelana ne-solvent kune-PA66 kodwa inokumunca umswakama ophezulu. Njengoba izici eziningi zekhwalithi zezingxenye zepulasitiki zithintwa ukumuncwa komswakama, lokhu kufanele kucatshangelwe ngokucophelela lapho uklama imikhiqizo nge-PA6.

Ukuqinisekisa izakhiwo zemishini ze-PA6, izinguqulo ezihlukahlukene zivame ukungezwa. I-Glass fiber iyisengezo esivamile, futhi irabha yokwenziwa ingase ihlanganiswe ukuze kuthuthukiswe ukumelana nomthelela.

Ku-PA6 engaqinisiwe, izinga lokuncipha liphakathi kuka-1% no-1.5%. Ukwengeza i-fiber yengilazi kunganciphisa ukushwabana kufinyelele ku-0.3% (nakuba iphakeme kancane ekuqondeni okuhambisana nokugeleza). Izinga lokugcina lokushwabana lithonywa ikakhulukazi ubucwebe nokumuncwa komswakama.

Iphuzu lesi-6: Umehluko Ezinqubweni Zokubumba Umjovo ze-PA6 ne-PA66

1. Ukwelashwa Kokomisa:

• I-PA6 imunca umswakama kalula, ngakho-ke ukomisa ngaphambi kokucubungula kubalulekile.
  • Uma okokusebenza kunikezwa emaphaketheni angangenwa umswakama, gcina isiqukathi sivaliwe.
  • Uma umswakama udlula u-0.2%, womise emoyeni oshisayo ku-80°C noma ngaphezulu amahora angu-3-4.
  • Uma kuvezwe emoyeni isikhathi esingaphezu kwamahora angu-8, kunconywa ukomiswa ngevacuum ku-105°C amahora angu-1-2.
  • Kunconywa umshini wokomisa umswakama.
• I-PA66 ayidingi ukomiswa uma impahla ivaliwe ngaphambi kokucubungula.
  • Uma isiqukathi sokugcina sivuliwe, somise emoyeni oshisayo ku-85°C.
  • Uma umswakama udlula u-0.2%, ukomiswa kwevacuum ku-105°C amahora angu-1-2 kuyadingeka.
  • Kunconywa ukomisa umswakama.

2. Izinga Lokushisa Lokubumba:

• I-PA6: 260–310°C (kumabanga aqinisiwe: 280–320°C).
• I-PA66: 260–310°C (amabanga aqinisiwe: 280–320°C).
