Me pēhea te tautuhi tika me te whiriwhiri i waenga i te PA6 me te PA66 kua whakarerekētia (Wāhanga 2)?

Tohu 5: Me pēhea te whiriwhiri i waenga i te PA6 me te PA66?

1. Mena kāore e hiahiatia he ātete pāmahana teitei i runga ake i te 187°C, whiriwhiria te PA6+GF, he iti ake te utu, he māmā ake hoki te tukatuka.
2. Mō ngā tono e hiahia ana ki te ātete pāmahana teitei, whakamahia te PA66+GF.
3. Ko te HDT (Heat Deflection Temperature) o PA66+30GF he 250°C, ko te PA6+30GF ia he 220°C.

He rite ngā āhuatanga matū me ngā āhuatanga ā-tinana o PA6 ki te PA66, engari he iti ake te ira rewa me te whānuitanga o te pāmahana tukatuka. He pai ake te ātete pānga me te ātete whakarewa i te PA66 engari he nui ake te mimiti makuku. Nā te mea he maha ngā āhuatanga kounga o ngā wāhanga kirihou e pāngia ana e te mimiti makuku, me āta whakaaro tēnei i te wā e hoahoa ana i ngā hua me te PA6.

Hei whakarite i ngā āhuatanga ā-pūkaha o te PA6, he maha ngā wā ka tāpirihia he momo whakarerekētanga. He mea tāpiri noa te muka karāhe, ā, ka taea hoki te whakauru i te rapa hangai hei whakarei ake i te ātete pānga.

Mō te PA6 kāore i whakakahangia, ko te tere whakahekenga kei waenganui i te 1% me te 1.5%. Mā te tāpiri muka karāhe ka taea te whakaiti i te whakahekenga ki te 0.3% (ahakoa he paku teitei ake i te ahunga poutū ki te rere). Ko te tere whakahekenga whakamutunga ka pāngia e te tioata me te mimiti makuku.

Tohu 6: Ngā Rerekētanga o ngā Tukanga Werohanga mō te PA6 me te PA66

1. Maimoatanga Whakamaroke:

• He tino ngāwari te mimiti a te PA6 i te makuku, nō reira he mea nui te whakamaroke i mua i te tukatuka.
  • Mena kei roto te rauemi i te takai ātete-makuku, me hiri te ipu.
  • Mena he nui ake te makuku i te 0.2%, whakamarokehia ki te hau wera i te 80°C, neke atu rānei, mō ngā haora 3–4.
  • Mena ka pāngia e te hau mō te neke atu i te 8 hāora, he mea pai kia whakamarokehia ki te mīhini korehau i te 105°C mō te 1–2 hāora.
  • E taunaki ana kia whakamahia he mīhini whakamaroke haumākū.
• Kāore e hiahiatia te whakamaroke i te PA66 mēnā kua hiritia te rauemi i mua i te tukatuka.
  • Mena kua whakatuwheratia te ipu rokiroki, whakamarokehia ki te hau wera i te 85°C.
  • Mena he nui ake te makuku i te 0.2%, me whakamaroke ki te mīhini korehau i te 105°C mō te 1–2 hāora.
  • E taunaki ana kia whakamahia he mīhini whakamaroke haumākū.

2. Te pāmahana whakapūtanga:

• PA6: 260–310°C (mō ngā kōeke whakapakari: 280–320°C).
• PA66: 260–310°C (mō ngā kōeke whakapakari: 280–320°C).
