ʻO ka Nylon (Polyamide, PA) kahi plastik hana kiʻekiʻe i hoʻohana nui ʻia i ka uila, automotive, textiles, a me nā māla ʻē aʻe. Ma muli o kona hiki ke ʻā, he mea nui ka hoʻololi ʻana i ke ahi o ka nylon. Aia ma lalo iho kahi hoʻolālā kikoʻī a me ka wehewehe ʻana o nā hoʻoheheʻe ʻana i ka lapalapa ahi o ka nylon, e uhi ana i nā mea hoʻonā ahi halogenated a me ka halogen-free flame retardant.
1. Nā Kumu o ka Hoʻolālā Hoʻolālā ʻAi ʻAi ʻAi ʻAi
ʻO ka hoʻolālā ʻana o nā hoʻolālā ahi ahi nylon e pili pono i kēia mau loina:
- ʻO ke ahi wela kiʻekiʻe: E hui i nā kūlana UL 94 V-0 a i ʻole V-2.
- Hana Hana: ʻAʻole pono e hoʻopilikia nui nā mea pale ahi i nā waiwai hana o ka nylon (e laʻa, ka wai, ke kūpaʻa wela).
- Na Waiwai Mechanical: ʻO ka hoʻohui ʻana o nā mea pale ahi e hōʻemi i ka hopena i ka ikaika o ka nylon, ʻoʻoleʻa, a me ke kūpaʻa ʻana o ke kapa.
- Aloha Kaiapuni: E hoʻopaʻa mua i nā mea pale ahi ʻole halogen e hoʻokō i nā lula kaiapuni.
2. Hoʻokumu ʻia ʻo Nailona hoʻopaʻa ʻia i ke ahi halogenated
ʻO nā mea hoʻopaʻa ahi halogenated (e laʻa, nā pūhui brominated) ke hoʻopau i nā hopena o ke kaulahao hoʻopau ʻana ma o ka hoʻokuʻu ʻana i nā radical halogen, e hāʻawi ana i ka maikaʻi o ke ahi.
Hoʻohui ʻia:
- Nailon resin (PA6 a i ole PA66): 100 phr
- Pale ahi i hoʻopaʻa ʻia: 10-20 phr (e laʻa, decabromodiphenyl ethane, polystyrene brominated)
- Antimony trioxide (synergist): 3-5 phr
- Lubricant: 1-2 phr (e laʻa, calcium stearate)
- Antioxidant: 0.5–1 phr (e laʻa, 1010 a i ʻole 168)
Kaʻina Hana:
- Premix nylon resin, flame retardant, synergist, lubricant, and antioxidant uniformly.
- E hoʻoheheʻe me ka hoʻohana ʻana i kahi extruder twin-screw a me ka pelletize.
- E mālama i ka mahana extrusion ma 240–280°C (hoʻololi ma muli o ke ʻano nylon).
Nā hiʻohiʻona:
- Nā pono: Kiʻekiʻe ahi retardant pono, haʻahaʻa additive nui, kumu kūʻai-pono.
- Nā pōʻino: Hiki ke hoʻokuʻu ʻia nā kinoea ʻawaʻawa i ka wā o ka puhi ʻana, nā pilikia kaiapuni.
3. Hoʻokumu ʻia ʻo Halogen-Free Flame Retardant Nylon
Hoʻohana nā mea hoʻopaʻa ahi ʻole halogen (e laʻa, phosphorus-based, nitrogen-based, a inorganic hydroxides) ma o ka hopena endothermic a i ʻole ka hoʻokumu ʻana i ka papa pale, e hāʻawi ana i ka hana kaiapuni ʻoi aku ka maikaʻi.
Hoʻohui ʻia:
- Nailon resin (PA6 a i ole PA66): 100 phr
- ʻAi i ka lapalapa ahi ma muli o ka phosphorus: 10-15 phr (e laʻa, ammonium polyphosphate APP a i ʻole phosphorus ʻulaʻula)
- Pākuʻi ʻia i ka lapalapa ahi ma muli o ka Nitrogen: 5–10 phr (e laʻa, melamine cyanurate MCA)
- ʻO ka waiʻawaʻawaʻawaʻawaʻole: 20-30 phr (e laʻa, magnesium hydroxide a i ʻole alumini hydroxide)
- Lubricant: 1-2 phr (e laʻa, zinc stearate)
- Antioxidant: 0.5–1 phr (e laʻa, 1010 a i ʻole 168)
Kaʻina Hana:
- Premix nylon resin, flame retardant, lubricant, and antioxidant uniformly.
- E hoʻoheheʻe me ka hoʻohana ʻana i kahi extruder twin-screw a me ka pelletize.
- E mālama i ka mahana extrusion ma 240–280°C (hoʻololi ma muli o ke ʻano nylon).
Nā hiʻohiʻona:
- Nā pono: Pili kaiapuni, ʻaʻohe hoʻokuʻu kinoea ʻona, kūpono i nā lula.
- Nā pōʻino: ʻOi aku ka maikaʻi o ka pale ʻana i ke ahi, ʻoi aku ka nui o nā mea hoʻohui, hiki ke hopena i nā waiwai mechanical.
4. Nā Manaʻo Nui ma ka Hoʻolālā Hoʻolālā
(1) Koho ʻana i ke ahi
- Nā mea pale ahi halogenated: Kiʻekiʻe ka maikaʻi akā hoʻopilikia i ke kaiapuni a me ke olakino.
- ʻO nā mea pale ahi ʻole halogen: Pili kaiaola akā makemake i nā huina nui a pili paha i ka hana waiwai.
(2) Hoʻohana i nā Synergists
- Antimony trioxide: Hana pū me nā mea hoʻopaʻa ahi halogenated e hoʻoikaika i ka hoʻopaʻa ahi.
- ʻO ka hui pū ʻana o Phosphorus-nitrogen: I loko o nā ʻōnaehana halogen, hiki i ka phosphorus a me ka nitrogen-based flame retardants hiki ke synergize e hoʻomaikaʻi i ka pono.
(3) Hoʻopuehu a hiki i ka hana
- Nā mea hoʻopuehu: E hōʻoia i ka hoʻopuehu like ʻana o nā mea hoʻopaʻa ahi e pale aku i nā kiʻekiʻe kiʻekiʻe kūloko.
- Nā Lubricants: E hoʻomaikaʻi i ka hoʻoheheʻe ʻana a hoʻemi i ka ʻaʻahu o nā mea hana.
(4) ʻO nā antioxidants
Kāohi i ka hōʻino ʻana o nā mea i ka wā e hana ai a hoʻonui i ka paʻa o ka huahana.
5. Nā noi maʻamau
- Mea uila: Nā ʻāpana pale ahi e like me nā mea hoʻohui, nā hoʻololi, a me nā kumu.
- Kaʻa kaʻa: Phr pale ahi e like me ka uhi mīkini, nā mea uwea, a me nā mea o loko.
- Nā lole lole: Nā pulupulu a me nā lole pale ahi.
6. Nā Manaʻo Hoʻolālā Hoʻolālā
(1) Hoʻonui i ka maikaʻi o ke ahi
- ʻO ka hui pū ʻana o ke ahi: Halogen-antimony a i ʻole phosphorus-nitrogen synergies e hoʻomaikaʻi i ka hana.
- Nā mea pale ahi nano: E laʻa, nano magnesium hydroxide a i ʻole nano pālolo, e hoʻonui i ka pono a hoʻemi i nā mea hoʻohui.
(2) Hoʻomaikaʻi i nā pono Mechanical
- Nā mea paʻakikī: E laʻa, POE a i ʻole EPDM, e hoʻoikaika i ka paʻakikī o nā mea a me ka pale ʻana i ka hopena.
- Hoʻoikaika i nā mea hoʻopihapiha: E laʻa, ke aniani aniani, e hoʻomaikaʻi i ka ikaika a me ka ʻoʻoleʻa.
(3) Ho'emi Kumukuai
- E hoʻonui i ka lakene pale ahi: E hoʻemi i ka hoʻohana ʻana i ka wā e hoʻokō ai i nā koi o ke ahi.
- E koho i nā mea waiwai: E laʻa, nā mea pale ahi i hui ʻia.
7. Nā Koina Kaiapuni a Hooponopono
- Nā mea pale ahi halogenated: Kāohi ʻia e RoHS, REACH, etc., e koi ana i ka hoʻohana akahele.
- ʻO nā mea pale ahi ʻole halogen: Kūlike me nā lula, e hōʻike ana i nā ʻano o ka wā e hiki mai ana.
Pono e noʻonoʻo i ka hoʻolālā ʻana o nā hoʻoheheʻe ahi nylon i nā hiʻohiʻona noi kikoʻī a me nā koi hoʻoponopono i ke koho ʻana i nā mea pale ahi halogenated a i ʻole halogen-free. Hāʻawi nā mea hoʻopaʻa ahi halogenated i ka hana kiʻekiʻe akā ke kū nei i nā pōʻino kaiapuni, ʻoiai ʻo nā mea ʻē aʻe halogen-free ʻoluʻolu kaiapuni akā makemake i nā mea hoʻohui nui. Ma o ka hoʻoponopono ʻana i nā hana a me nā kaʻina hana, hiki ke hoʻomohala ʻia nā mea pono o ka uila, kaʻa, textiles, a me nā ʻoihana ʻē aʻe.
