Me pēhea te tautuhi tika me te whiriwhiri i waenga i te PA6 me te PA66 kua whakarerekētia (Wāhanga 1)?

I te piki haere o te pakari o te hangarau R&D nairona whakarerekētia, kua whānui haere te whānuitanga o te tono o PA6 me PA66. He maha ngā kaihanga hua kirihou, ngā kaiwhakamahi rānei o ngā hua kirihou nairona kāore i te mārama ki ngā rerekētanga i waenga i te PA6 me te PA66. Hei tāpiri, nā te mea kāore he rerekētanga tirohanga mārama i waenga i te PA6 me te PA66, kua ara ake te maha o ngā whakapoauautanga. Me pēhea te wehewehe i te PA6 me te PA66, ā, me pēhea te whiriwhiri i a rāua?

Tuatahi, Ngā Tohutohu mō te Tāutu i te PA6 me te PA66:
Ina tahuna, ka puta he kakara rite ki te huruhuru hipi, ki ngā whao rānei kua tahuna te PA6 me te PA66. Ka puta he mura kōwhai i te PA6, ko te PA66 ia ka mura ki te mura kikorangi. He pakari ake te PA6, he iti ake te utu i te PA66, ā, he iti ake te ira rewa (225°C). He kaha ake te PA66, he ātete pai ake ki te kakahu, ā, he teitei ake te ira rewa (255°C).

Tuarua, Ngā Rerekētanga o ngā Āhuatanga Ā-tinana:

• PA66:Te ira rewa: 260–265°C; te pāmahana whakawhiti karāhe (āhua maroke): 50°C; te mātotoru: 1.13–1.16 g/cm³.
• PA6:He pire polymer tioata mā-miraka, āhua mārama, he mātotoru rānei; te ira rewa: 220°C; te pāmahana pirau: neke atu i te 310°C; te mātotoru whanaunga: 1.14; te mimiti wai (24 hāora i roto i te wai i te 23°C): 1.8%. He tino pai te ātete ki te kakahu me te whakahinuhinu-ā-ia anō, he kaha miihini teitei, he ātete wera me ngā āhuatanga whakamahana hiko pai, he pai te mahi pāmahana iti, he āhuatanga tine-ā-ia anō, me te ātete matū—ina koa te ātete hinu.

Ki te whakaritea ki te PA66, he māmā ake te tukatuka me te hanga i te PA6, he pai ake te kanapa o te mata i roto i ngā hua kua oti, ā, he whānui ake te awhe pāmahana e taea ai te whakamahi. Heoi, he nui ake te mimiti wai, ā, he ngoikore te pumau o ngā āhuatanga. He iti ake te pakari, he iti ake te ira rewa, ā, ka taea te whakamahi mō ngā wā roa i roto i ngā taiao uaua. He pai te ātete ki te ahotea puta noa i te awhe pāmahana whānui, me te pāmahana ratonga tonu o te 105°C.

Tuatoru, Me pēhea te whakatau mēnā ka whakamahia te PA66, te PA6 rānei?
Te whakataurite i te mahi i waenga i te PA6 me te PA66:

• Ngā āhuatanga miihini: PA66 > PA6
• Mahi wera: PA66 > PA6
• Utu: PA66 > PA6
• Te pūwāhi rewa: PA66 > PA6
• Te mimiti wai: PA6 > PA66

Tuawhā, Ngā Rerekētanga o te Whānuitanga o te Tono:

• Ngā kirihou hangarau PA6He kaha te kume, he ātete pai ki te pānga, he ātete pai ki te kakahu, he ātete matū, ā, he iti te tauwehenga waku. Mā ngā whakarerekētanga pēnei i te whakakaha muka karāhe, te whakakī kohuke, ngā tāpiringa ārai mura rānei, ka taea te whakapai ake i tō rātou mahi whānui. E whakamahia nuitia ana ēnei i roto i te umanga motuka me ngā mara hiko/hiko.
• PA66He tino pai te mahi whānui, tae atu ki te kaha teitei, te pakari, te ātete pānga, te ātete hinu me te matū, te ātete kakahu, me te whakahinuhinu-ake. He tino pai ki te pakeke, te pakari, te ātete wera, me te ātete ngoki. Nā tōna kaha teitei ake i te PA6, he nui ake te whakamahinga o te PA66 i roto i ngā mahi ahumahi pēnei i te hanga taura potae.
