Ni gute wamenya neza kandi ugahitamo hagati ya PA6 yahinduwe na PA66 (Igice cya 2)?

Ingingo ya 5: Nigute wahitamo hagati ya PA6 na PA66?

1. Iyo ubushyuhe bwinshi buri hejuru ya 187°C budakenewe, hitamo PA6+GF, kuko ihendutse kandi yoroshye kuyitunganya.
2. Ku bikoresho bisaba ubushyuhe bwinshi, koresha PA66+GF.
3. HDT (Ubushyuhe bwo Guhindura Ubushyuhe) ya PA66+30GF ni 250°C, mu gihe iya PA6+30GF ari 220°C.

PA6 ifite imiterere ya shimi n'iy'umubiri nk'iya PA66, ariko ifite aho ishongesha hato kandi ikagira ubushyuhe bwinshi bwo kuyitunganya. Itanga ubudahangarwa bwiza bwo guhangana n'ingaruka no kudahangarwa n'ibintu bihumanya kurusha PA66 ariko ifite ubushobozi bwo gufata amazi menshi. Kubera ko imiterere myinshi y'ibice bya pulasitiki igira ingaruka ku gushonga k'amazi, ibi bigomba kwitabwaho cyane mu gushushanya ibicuruzwa bifite PA6.

Kugira ngo hamenyekane imiterere ya PA6 mu buryo bw’ikoranabuhanga, hakunze kongerwamo ibintu bitandukanye bihindura. Fibre y’ikirahure ni inyongera isanzwe, kandi rubber y’ubukorikori ishobora no gushyirwamo kugira ngo yongere ubushobozi bwo kurwanya ingaruka.

Ku bijyanye na PA6 idakomejwe, igipimo cyo kugabanuka kiri hagati ya 1% na 1.5%. Kongeramo fibre y'ikirahure bishobora kugabanya kugabanuka kugeza kuri 0.3% (nubwo biri hejuru gato mu cyerekezo cy'amazi). Igipimo cyo kugabanuka kwa nyuma ahanini giterwa n'ubushyuhe n'uburyo amazi yinjizwamo.

Ingingo ya 6: Itandukaniro mu buryo bwo gushushanya inshinge kuri PA6 na PA66

1. Uburyo bwo kumisha:

• PA6 ifata ubushuhe byoroshye cyane, bityo kumisha mbere yo gutunganya ni ingenzi cyane.
  • Niba ibikoresho bitanzwe mu ipaki idapfa guhumeka, komeza ufunze igikoresho.
  • Niba ubushuhe burenze 0.2%, bumutse mu kirere gishyushye kuri 80°C cyangwa hejuru yayo mu gihe cy'amasaha 3-4.
  • Iyo bishyizwe mu mwuka mu gihe kirenze amasaha 8, ni byiza kubyutsa mu cyuma gishyushye kuri 105°C mu gihe cy'isaha 1-2.
  • Icyuma cyumisha amazi gitanga ubushuhe ni byiza.
• PA66 ntisaba kumisha ibikoresho iyo bifunze mbere yo kubitunganya.
  • Niba igikoresho cyo kubikamo cyarafunguwe, gikanike mu mwuka ushyushye kuri dogere selisiyusi 85.
  • Niba ubushuhe burenze 0.2%, ni ngombwa kumisha amazi mu buryo bwa vacuum kuri 105°C mu gihe cy'isaha 1-2.
  • Icyuma cyumisha amazi gitanga ubushuhe ni byiza.

2. Ubushyuhe bwo Gutunganya:

• PA6: 260–310°C (ku gipimo cy’ubushyuhe: 280–320°C).
• PA66: 260–310°C (ku gipimo cy’ubushyuhe: 280–320°C).
