- Solvent: Pe a manaʻomia (fetuunaʻi le viscosity).
Uiga:
- Tulaga lelei: Maua le afi maualuga, maualalo le aofaʻi faʻaopoopo.
- Fa'aletonu: E ono maua mai kasa oona i le taimi e mu ai; popolega tau le siosiomaga.
3. Fa'apipi'i Fa'apipi'i Fa'asa'o e Fa'asa'o 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 le inorganic hydroxides) e galue e ala i tali endothermic po'o le fa'avaeina o vaega puipui, e maua ai le fa'atinoga lelei o le si'osi'omaga.
Vaega Fausia:
- Mea Fa'amau Fa'amau: Epoxy resin, polyurethane, po'o le acrylic.
- Fofofo-Fa'asa'o Mumu: 10–15% (faataitaiga,ammonium polyphosphate APPpoʻo le phosphorus mumu).
- Fa'asa'oina o le Afi o le Nitrogen: 5–10% (faataitaiga, melamine cyanurate MCA).
- Hydroxides e le fa'aogaina: 20–30% (fa'ata'ita'iga, aluminium hydroxide po'o le magnesium hydroxide).
- Fa'apalaisa: 1–3% (faaleleia le fetuutuunai).
- Sui Fa'amalolo: Filifilia e faavae ile ituaiga pipii.
- Solvent: Pe a manaʻomia (fetuunaʻi le viscosity).
Uiga:
- Tulaga lelei: Fa'alelei le si'osi'omaga, leai ni kasa oona, fa'atulafonoina.
- Fa'aletonu: Fa'aitiitia le afi fa'afefeteina, maualuga le aofa'i fa'aopoopo, e ono a'afia ai mea fa'ainisinia.
4. Manatu Autu ile Fuafuaga Fa'atulagaina
- Filifiliga Fa'amumu:
- Halogenated: maualuga le lelei ae o loʻo iai aʻafiaga o le siosiomaga ma le soifua maloloina.
- Halogen-Free: Eco-friendly ae manaʻomia ni aofaʻi tele.
- Fegalegaleaiga: Ia mautinoa o le mu e le mafai ona faʻapupulaina pe faʻaitiitia le faʻaogaina o le fusi.
- Fa'agaioiga: Aloese mai le fa'alavelave i le fofo ma le fa'afefe.
- Siosiomaga Tausi: Mana'omia filifiliga e leai se halogen e fetaui ma RoHS, REACH, ma isi.
5. Talosaga masani
- Fausia: Fa'amau fa'amaufa'ailoga afi, fa'apipi'i fa'avae.
- Fa'aeletonika: Fa'apipi'i fa'apipi'i laupapa li'o, fa'apipi'i fa'aulu.
- Ta'avale: Fa'apipi'i moli ulu, fa'apipi'i totonu.
6. Fautuaga mo le Fa'atulagaina o Fa'atonuga
- Fa'aleleia o le Mumu:
- Fa'atasiga fa'atasi (fa'ata'ita'iga, halogen-antimony, phosphorus-nitrogen).
- 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 o mea fa'aopoopo.
- Fa'aleleia Meatotino Fa'ainisinia:
- Tougheners (fa'ata'ita'iga, POE po'o le EPDM) e fa'aleleia atili ai le fetu'una'i ma le a'afiaga.
- Fa'amalosia mea fa'atumu (fa'ata'ita'iga, alava tioata) e fa'ateleina ai le malosi ma le ma'a'a'a.
- Fa'aitiitiga o tau:
- Fa'asili le fua o le mu e fa'aitiitia ai le fa'aoga a'o fa'amalieina mana'oga.
- Filifili mea e taugofie (fa'ata'ita'iga, mea fa'ale-aiga po'o fa'afefiloi afi mumu).
7. Siosiomaga ma Tulafono Fa'atonu Manaoga
- Fa'afiofi Mu'amu: Faʻatapulaʻaina i lalo ole RoHS, REACH, ma isi; faaaoga ma le faaeteete.
- Fa'agata Mu-Afi e leai se Halogen: Ia tausisia tulafono faatonutonu; agai i luma.
8. Aotelega
Fa'apipi'i fa'aluma afi e tatau ona fa'atulagaina e fa'atatau i fa'aoga ma'oti ma mana'oga fa'atulafonoina, filifili i le va o le halogenated po'o le halogen-free options. 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 ai le tele o mea fa'aopoopo. E ala i le fa'amalieina o fa'asologa ma faiga, e mafai ona atia'e ni fa'apipi'i fa'alumaina afi, fa'aeletonika, ta'avale, ma isi pisinisi.
