Fuafuaga Suiga mo Halogen-Free Flame Retardant PVC Pa'u

Folasaga

O lo'o gaosia e le tagata o tausia le pa'u PVC e fa'afefe mu ma fa'aaoga muamua le antimony trioxide (Sb₂O₃). Ua latou taumafai nei e aveese le Sb₂O₃ ma sui i mea e mumu ai le halogen. O le faʻatulagaina o loʻo iai nei e aofia ai le PVC, DOP, EPOXY, BZ-500, ST, HICOAT-410, ma le antimony. O le suiga mai se faiga pa'u PVC e fa'atatau i le antimony i se faiga e fa'asa'o ai le afi e leai se halogen e fa'atusalia ai se fa'aleleia atili fa'atekonolosi. O lenei suiga e le gata ina mulimulita'i i tulafono fa'alesiosiomaga ua fa'atuputeleina (fa'ata'ita'iga, RoHS, REACH) ae fa'apena fo'i le fa'aleleia atili o le ata "lanumeamata" o le oloa ma le fa'atauva'a o maketi.

Lu'itau Autu

  4. Fa'atinoga Fa'atinoga:
    • O uta maualuga o mea fa'atumu e leai se halogen (fa'ata'ita'iga, ATH) e ono a'afia ai le tafe liusuavai ma le mautu o gaioiga.
  5. Mana'oga tau:
    • O nisi mea e fa'agata ai afi e leai ni halogen maualuga e taugata, e mana'omia ai se paleni i le va o le fa'atinoga ma le tau.

Fuafuaga Filifilia mo Faiga Fa'asa'o Mu-Afi e Sa'oloto (mo Pa'u Fa'a PVC)

1. Fa'agata Muamua - Metal Hydroxides

  • Aluminium Trihydroxide (ATH):
    • E sili ona taatele, taugofie.
    • Mechanism: Endothermic decomposition (~ 200°C), faʻasaʻo vai ausa e faʻafefe ai kasa mumu ma le okesene aʻo fausia ai se faʻavae puipui.
    • Fa'aletonu: E maualalo le lelei, maualuga le uta e mana'omia (40-70 phr), fa'aitiitia ai le vaivai, fa'aumiumi, ma le fa'agasologa; e maualalo le vevela o le pala.
