Nylon (Polyamide, PA) o se palasitika faʻainisinia maualuga faʻaaogaina lautele i mea tau eletise, taʻavale, ie, ma isi faʻalapotopotoga. Ona o lona mu, e matua taua tele le suia o le nailo e taofia ai le mu. O lo'o i lalo se fa'amatalaga au'ili'ili ma fa'amatalaga o fa'auiga e fa'asa'o ai le afi, e aofia uma fo'i vaifofo fa'asao fa'ama'i ma mea e leai se afi.
1. Fa'avae ole Fuafuaga Fa'asa'o ole Nailoni Afi
Ole mamanu ole nailoni e fa'afefeteina afi e tatau ona mulimulita'i i ta'iala nei:
- Malosi o le afi mumu: Faʻafeiloaʻi UL 94 V-0 poʻo le V-2 faʻataʻitaʻiga.
- Fa'agaioiina Fa'atinoga: E le tatau ona matua a'afia mea e fa'amama ai le mu o le nailoni (fa'ata'ita'iga, sua, mautu fa'amama).
- Meatotino Fa'ainisinia: O le fa'aopoopoina o mea fa'afefe mu e tatau ona fa'aitiitia le a'afiaga i le malosi o le nailoni, malō, ma le fa'alavalava.
- Siosiomaga Faauo: Fa'amuamua mea fa'afefe mu e leai se halogen e fa'amalieina tulafono fa'alesiosiomaga.
2. Fausia le Nailo Fa'asa'o Fa'asa'o
O mea fa'afefe mu (fa'ata'ita'iga, mea fa'apalapala) fa'alavelaveina fa'agaioiga o filifili afi e ala i le fa'asa'olotoina o fa'amalama halogen, e maua ai le lelei tele o le mu.
Fa'atulagaina o mea:

- Fa'afefiloi fa'afefiloi e fa'aaoga ai se masini fa'apipi'i fa'aulu ma pelletize.
- Pulea le vevela o le extrusion ile 240–280°C (fetuuna'i e fa'atatau ile ituaiga nailon).
Uiga:
- Tulaga lelei: Maua le afi mumu, maualalo le aofaʻi faaopoopo, taugofie.
- Fa'aletonu: E mafai ona fa'asa'olotoina kasa o'ona a'o mu, atugaluga o le si'osi'omaga.
3. Fausia Nailoni e Fa'asa'o ai le Afi e Sa'o Halogen
O mea e taofia ai le mu e leai se halogen (fa'ata'ita'iga, phosphorus-based, nitrogen-based, po'o inorganic hydroxides) e galue e ala i tali endothermic poʻo le faʻavaeina o le puipuiga, e maua ai le faʻaleleia atili o le siosiomaga.
Fa'atulagaina o mea:
- Nailoni resini (PA6 po'o PA66): 100 phr
- Fa'asa'o fa'avae phosphorus mumu mumu: 10–15 phr (fa'ata'ita'iga, ammonium polyphosphate APP po'o le phosphorus mumu)
- Fa'asa'o le mu e fa'avae i le nitrogen: 5–10 phr (fa'ata'ita'iga, melamine cyanurate MCA)
- Hydroxide fa'a-natura: 20-30 phr (fa'ata'ita'iga, magnesium hydroxide po'o le alumini hydroxide)
- Lubricant: 1–2 phr (faataitaiga, zinc stearate)
- Antioxidant: 0.5–1 phr (faataitaiga, 1010 po o le 168)
Fa'agaioiga Laasaga:
- Premix nylon resin, mumu mumu, lubricant, ma antioxidant tutusa tutusa.
- Fa'afefiloi fa'afefiloi e fa'aaoga ai se masini fa'apipi'i fa'aulu ma pelletize.
- Pulea le vevela o le extrusion ile 240–280°C (fetuuna'i e fa'atatau ile ituaiga nailon).
Uiga:
- Tulaga lelei: Siosiomaga, leai se kasa oona, tausisia tulafono faatonutonu.
- Fa'aletonu: Fa'aitiitia le afi fa'afefeteina o le afi, maualuga le aofa'i o mea fa'aopoopo, a'afiaga i mea fa'ainisinia.
4. Manatu Autu ile Fuafuaga Fa'atulagaina
(1) Filifiliga Fa'amumu
- Fa'aliga fa'amumu: maualuga le lelei ae o lo'o a'afia ai le si'osi'omaga ma le soifua maloloina.
- Fa'agata afi e leai se halogen: Fa'alelei ae mana'omia ni aofa'iga tetele ma e ono a'afia ai le fa'atinoga o meafaitino.
(2) Fa'aaogaina o Synergists
- Antimony trioxide: Galulue fa'atasi ma mea fa'afefe mu e fa'aleleia ai le mu.
- Phosphorus-nitrogen synergy: I faiga e leai ni halogen, phosphorus ma nitrogen-based flame retardants e mafai ona galulue faatasi e faaleleia atili ai le lelei.
(3) Ta'ape ma Fa'agaioiina
- Fa'asalalau: Fa'amautinoa le fa'asalalauina tutusa o mea e fa'afefe ai le afi e 'alofia ai fa'aputuga maualuga.
- Lubricants: Faʻaleleia le faʻaogaina o le suavai ma faʻaitiitia le ofuina o meafaigaluega.
(4) Antioxidants
Puipuia le faaleagaina o meafaitino i le faagasologa o le gaosiga ma faaleleia le mautu o oloa.
5. Talosaga masani
- Fa'aeletonika: Vaega e le mu e pei o so'o, ki, ma sockets.
- Ta'avale: Phr e le mu e pei o ufiufi afi, uaea uaea, ma vaega o totonu.
- 'ie: Alava mumu ma ie.
6. Fautuaga mo le Fa'atulagaina o Fa'atonuga
(1) Fa'asiliina le Fa'asa'oina o le Mu
- Fa'afefiloi e mumu mu: Halogen-antimony poʻo le phosphorus-nitrogen synergies e faʻaleleia ai le faʻatinoga.
- Nano fa'aluma afi: Fa'ata'ita'iga, nano magnesium hydroxide po'o nano omea, e fa'aleleia atili ai le lelei ma fa'aitiitia le aofa'i fa'aopoopo.
(2) Fa'aleleia Meatotino Fa'ainisinia
- Malolosi: Fa'ata'ita'iga, POE po'o le EPDM, e fa'aleleia atili ai le malosi o meafaitino ma le a'afiaga.
- Faʻamalosia mea faʻatumu: Fa'ata'ita'iga, alava tioata, e fa'aleleia atili ai le malosi ma le ma'a'a'a.
(3) Fa'aitiitiga o tau
- Fa'ateteleina fua faatatau o le mu: Fa'aiti'itia le fa'aoga a'o fa'amalieina mana'oga mo le fa'alumaina.
- Filifili mea taugofie: Fa'ata'ita'iga, mea fa'ale-aiga po'o fa'afefiloi afi mumu.
7. Siosiomaga ma Tulafono Fa'atonu Manaoga
- Fa'aliga fa'amumu: Faʻatapulaʻaina e RoHS, REACH, ma isi, e manaʻomia ai le faʻaoga faʻaeteete.
- Fa'agata afi e leai se halogen: Fa'ata'ita'i ma fa'atonuga, fa'atusalia aga'i i luma.
Ole mamanu ole nailoni e fa'asa ai le afi e tatau ona mafaufau i fa'ata'ita'iga fa'apitoa ma mana'oga fa'atonutonu pe a filifilia ni mea fa'amalama e leai se afi. O mea e fa'afefeteina o le afi e ofoina atu le maualuga o le lelei ae o lo'o a'afia ai le si'osi'omaga, a'o isi mea e leai ni halogen e fa'alelei i le si'osi'omaga ae e mana'omia ni fa'aopoopoga tetele. E ala i le fa'avasegaina o fa'asologa ma fa'agasologa, e mafai ona fa'atupuina mea fa'akomepiuta fa'aeletonika, ta'avale, ie, ma isi fale gaosi oloa.
