Fa'aoga:
- Talafeagai mo faiga faavae mumu mu.
- Fautuaina e tu'u fa'atasi ma synergists (fa'ata'ita'iga, zinc borate).
Zinc Borate
Tulaga lelei:
- Synergistic mumu mumu, faʻaleleia le aoga ATH.
- Fa'ateleina le fa'atupuina o le asu ma taofia le asu.
Fa'aletonu:
- Fa'atapula'a le aoga pe a fa'aaogaina na'o; e mana'omia le tu'ufa'atasia ma isi fa'amalama afi.
Fa'aoga:
- Fautuaina e avea o se synergist mo ATH poʻo alumini hypophosphite.
Aluminium Hypophosphite
Tulaga lelei:
- E sili ona lelei, leai se halogen, maualalo le uta (10-20 phr).
- Lelei faʻamautu faʻamafanafana, talafeagai mo manaʻoga maualuga mumu.
Fa'aletonu:
- Tau maualuga.
- O feso'ota'iga ma faiga latex e mana'omia le fa'amaonia.
Fa'aoga:
- E fetaui mo tulaga maualuga o le mumu (fa'ata'ita'iga, UL94 V-0).
- E mafai ona faʻaaogaina naʻo ia pe faʻatasi.
MCA (Melamine Cyanurate)
Tulaga lelei:
- Fa'asao le afi fa'avae nitrogen, fa'afefe asu.
Fa'aletonu:
- Le lelei le ta'ape.
- E ono fa'alavelave i le fa'asusu.
- O le vevela vevela maualuga (~ 300 ° C), e le fetaui ma le gaosiga o le latex maualalo.
Fa'aoga:
- E le fautuaina e fai ma fa'amuamua; mana'omia le fa'ata'ita'iga fa'amaonia.
II. Fautuaga Fautuaga ma Fautuaga Faagaioiga
Fuafuaga 1: ATH + Zinc Borate (Filifiliga Tau Tamaoaiga)
Tulaga:
- Aluminium Hydroxide (ATH): 30-40 phr
- Zinc Borate: 5-10 phr
- Dispersant (fa'ata'ita'iga, so'o fa'apipi'i silane): 1-2 phr (fa'aleleia le ta'ape)
Uiga:
- Tau maualalo, fa'alelei le si'osi'omaga.
- E fetaui mo mana'oga lautele mo le mu (fa'ata'ita'iga, UL94 HF-1).
- E mafai ona faʻaitiitia teisi le faʻaleleia o le omomi; Vulcanization optimization mana'omia.
Fuafuaga 2: Aluminium Hypophosphite + Zinc Borate (Filifiliga Maualuga)
Tulaga:
- Aluminium Hypophosphite: 15-20 phr
- Zinc Borate: 5-8 phr
- Plasticizer (fa'ata'ita'iga, paraffin vai): 2-3 phr (fa'aleleia le fa'agaioiina)
Uiga:
- Maua maualuga le fa'alumaina o le afi, maualalo le utaina.
- Talafeagai mo fa'aaliga maualuga mana'omia (fa'ata'ita'iga, fa'amumu i luga V-0).
- O le fetaui o le alumini hypophosphite ma le latex e manaʻomia le suʻega.
Fuafuaga 3: ATH + Alumini Hypophosphite (Filifiliga Paleni)
Tulaga:
- Aluminium Hydroxide: 20-30 phr
- Aluminium Hypophosphite: 10-15 phr
- Zinc Borate: 3-5 phr
Uiga:
- Fa'apaleni tau ma fa'atinoga.
- Faʻaitiitia le faʻalagolago i se afi mumu e tasi, faʻaitiitia le aʻafiaga i mea faitino.
III. Fa'atonuga o Fa'agasologa
Ta'apeina:
- E tatau ona fa'afefete afi mumu i le ≤5μm e aloese ai mai le afaina o le fausaga foam.
- E fautuaina le faʻasalalau muamua i le latex poʻo le televave o mea faʻafefiloi.
Tulaga Fa'amalolo:
- Pulea le vevela o le fofo (e masani lava 110-130°C mo le latex) e puipuia ai le vave pala o mea e taofia ai le mu.
Su'ega Fa'atinoga:
- Suʻega taua: Oxygen Index (LOI), Vertical Burn (UL94), Density, Resilience.
- Afai e le lava le mumu o le afi, faasolosolo malie ona faateleina le alumini hypophosphite poʻo le ATH ratios.
IV. Fautuaga Faaopoopo
Su'ega MCA:
- Afai e fa'ata'ita'i, fa'aaoga le 5-10 phr i ni vaega laiti e va'ai ai le a'afiaga o le fa'a'ofu'ofu o le tutusa.
Tusipasi Siosiomaga:
- Ia fa'amautinoa o lo'o fa'atumauina e fa'agata mumu le RoHS/REACH mo fa'atau atu i fafo.
Fa'afefiloiga Synergistic:
- Mafaufau e fa'aopoopo i ai ni vaega laiti ole nanoclay (2-3 phr) e fa'aleleia atili ai a'afiaga o pa puipui.
