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

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

1. Uma kungadingeki ukumelana nokushisa okuphezulu okungaphezu kuka-187°C, khetha i-PA6+GF, njengoba ingabizi kakhulu futhi kulula ukuyicubungula.
2. Ngezinhlelo zokusebenza ezidinga ukumelana nokushisa okuphezulu, sebenzisa i-PA66+GF.
3. I-HDT (Izinga lokushisa lokushintsha kokushisa) le-PA66+30GF lingu-250°C, kanti ele-PA6+30GF lingu-220°C.

I-PA6 inezakhiwo zamakhemikhali nezomzimba ezifana ne-PA66, kodwa inezinga eliphansi lokuncibilika kanye nobubanzi bokushisa bokucubungula obubanzi. Inikeza ukumelana okungcono komthelela kanye nokumelana nesinyibilikisi kune-PA66 kodwa inokumuncwa komswakama okuphezulu. Njengoba izici eziningi zekhwalithi zezingxenye zepulasitiki zithinteka ukumuncwa komswakama, lokhu kufanele kucatshangelwe ngokucophelela lapho kuklanywa imikhiqizo ene-PA6.

Ukuqinisekisa izakhiwo ze-PA6, kuvame ukungezwa ama-modifiers ahlukahlukene. I-fiber yengilazi iyisengezo esivamile, futhi irabha yokwenziwa nayo ingafakwa ukuze kuthuthukiswe ukumelana nokushayisana.

Ku-PA6 engaqiniswanga, izinga lokuncipha liphakathi kuka-1% no-1.5%. Ukwengeza i-fiber yengilazi kunganciphisa ukuncipha kube ngu-0.3% (nakuba kuphakeme kancane ohlangothini oluqondile nokugeleza). Izinga lokugcina lokuncipha lithonywa kakhulu yi-crystallinity kanye nokumuncwa komswakama.

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

1. Ukwelashwa Kokomisa:

• I-PA6 imunca umswakama kalula kakhulu, ngakho-ke ukomisa ngaphambi kokucubungula kubalulekile.
  • Uma izinto zitholakala emaphaketheni angangeni umswakama, gcina isitsha sivaliwe.
  • Uma okuqukethwe komswakama kudlula u-0.2%, komise emoyeni oshisayo ku-80°C noma ngaphezulu amahora angu-3-4.
  • Uma kubekwe emoyeni isikhathi esingaphezu kwamahora angu-8, kunconywa ukomisa nge-vacuum ku-105°C isikhathi esingamahora angu-1-2.
  • Kunconywa umshini wokomisa osusa umswakama.
• I-PA66 ayidingi ukomiswa uma izinto zivaliwe ngaphambi kokucutshungulwa.
  • Uma isitsha sokugcina sivuliwe, somise emoyeni oshisayo ku-85°C.
  • Uma okuqukethwe komswakama kudlula u-0.2%, ukomisa nge-vacuum ku-105°C amahora angu-1-2 kuyadingeka.
  • Kunconywa umshini wokomisa osusa umswakama.

2. Izinga Lokushisa Lokubumba:

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