Fa'asinoga Fa'asinomaga mo V-0 Fa'alumaina PVC Thermoplastic Plastics

Ina ia ausia se fua faatatau V-0 mumu mumu (e tusa ai ma UL-94 tulaga) i PVC thermoplastic plastics, alumini hypophosphite ma boric acid o lua e masani ona faʻaaogaina afi mumu. O latou tulaga fa'aopoopo e mana'omia ona fa'asilisiliina fa'atatau i le fa'atulagaina fa'apitoa, tulaga fa'agaioiga, ma mana'oga fa'atinoga. O lo'o i lalo nisi o fautuaga ma vaega fa'asino:

1. Laasaga Faaopoopo o Alumini Hypophosphite

Alumini hypophosphite o se phosphorus-faʻavae mu retardant lelei talafeagai mo mea PVC. E taofia ai le mu e ala i le faia o se vaega phosphate puipuia ma tuʻuina atu le kasa phosphoric acid.

• Laasaga fa'aopoopo fautuaina: 15–25 ph(vaega ile selau vaega ole resin)
• Mo PVC masani, faʻaopoopo faʻatasi20 phole alumini hypophosphite e masani lava ona ausia le V-0 fua fa'atatau o le mu.
• Mo le maualuga o le mumu, e mafai ona faʻateleina le fua, ae o le aʻafiaga i mea faʻainisinia e tatau ona mafaufau i ai.
• Fa'aeteetega:
• Ole alumini alumini hypophosphite e mafai ona fa'aitiitia ai le fa'atinoina o galuega (fa'ata'ita'iga, le lelei le tafe).
• E fautuaina e tu'u fa'atasi ma isi mea fa'afefe mu (eg, boric acid, alumini hydroxide) mo a'afiaga fa'atasi.

2. Laasaga Faaopoopo o le Boric Acid

O le Boric acid ose mumu e fa'amu'amu'a maualalo le tau e galue muamua e ala i le fa'aleagaina o le endothermic ma le fa'atūina o se fa'amalama puipui e pei o tioata.

• Laasaga fa'aopoopo fautuaina: 5–15 ph
• O le boric acid e masani ona faʻaaogaina e avea o se faʻamaʻi mumu lona lua, ma o le tele o aofaiga e ono faʻaleagaina ai mea faʻainisinia ma gaioiga.
• I le PVC, faʻaopoopo faʻatasi10 pho le boric acid e mafai ona faʻatasi ma le alumini hypophosphite e faʻaleleia ai le mumu.
• Fa'aeteetega:
• Boric acid e hygroscopic, o le teuina ma le tagofiaina e tatau ona aloese mai le susū.
• E fa'atapula'aina lona a'afiaga o le mu pe a fa'aaogaina na'o ia; e masani lava ona tu'ufa'atasia ma isi mea e fa'afefe mu (fa'ata'ita'iga, alumini hypophosphite, alumini hydroxide).

3. Fausiaina Synergistic o Alumini Hypophosphite ma Boric Acid

Ina ia ausia se fua faatatau V-0, alumini hypophosphite ma boric acid e mafai ona tuʻufaʻatasia mo aʻafiaga synergistic. O loʻo i lalo se faʻasologa o faʻamatalaga:

• Aluminium hypophosphite: 15–20 ph
• Boric acid: 5–10 ph
• isi mea fa'aopoopo:
• Plasticizer (fa'ata'ita'iga, DOP): Pe a mana'omia (fetuuna'i e fa'atatau i mana'oga ma'a'a PVC)
• Fa'amautu:2–5 ph(fa'ata'ita'iga, masima ta'ita'i, fa'amautu calcium-zinc)
• Lubricant:0.5–1 ph(faataitaiga, stearic acid)

Fa'ata'ita'iga Fa'atusa:

• PVC resini:100 ph
• Aluminium hypophosphite:18 ph
• Zinc borate:8 phr
• Fa'apipi'i (DOP):40 ph
• Fa'amautu:3 phr
• Lubricant:0.8 ph

4. Su'ega ma Fa'atonuga

I faʻatinoga faʻatinoga, o laasaga nei e fautuaina mo suʻega ma faʻalelei:

1. Fa'atonuga pailate:Saunia se faʻataʻitaʻiga laʻititi e faʻavae i luga o laina faʻasino.
2. Su'ega UL-94:Fa'atino su'ega mu i luga o le sa'o e iloilo ai le fua fa'atatau o le mu.
3. Su'ega fa'atinoga:Iloilo mea fa'ainisinia (fa'ata'ita'iga, malosi fa'amalosi, malosi o a'afiaga) ma fa'atinoga fa'agaioiga (fa'ata'ita'iga, fe'avea'i, mautu le vevela).
4. Fa'atonuga:Fetuuna'i le maualuga o le alumini hypophosphite ma le boric acid po'o le fa'aofiina o isi mea e fa'afefe mu (fa'ata'ita'iga, alumini hydroxide, antimony trioxide) e fa'aleleia atili ai le fa'atinoga.

5. Manatu Autu

• Fa'agasologa o le vevela:O le vevela o le alumini hypophosphite ma le boric acid e maualuga tele; fa'amautinoa e le sili atu le vevela o le gaosiga i nei tapula'a e aloese ai mai le fa'aleagaina.
• Ta'ape:Ia fa'amautinoa le fa'asalalauina tutusa o fa'ama'i afi i le PVC e puipuia ai fa'afitauli fa'apitonu'u.
• Aafiaga ole siosiomaga:O le alumini hypophosphite ma le boric acid e faʻafefe ai le afi, ae e tatau ona faʻamaonia le fetaui ma isi faʻaopoopoga.

6. Fa'ai'uga

Ina ia ausia se fua faatatau V-0 mumu i totonu o PVC thermoplastic plastics, o la'asaga fa'aopoopo fautuaina e15-25 itula mo le alumini hypophosphitema5-15 itula mo le boric acid. O le fa'aogaina fa'atasi o nei fa'amalama mu e mafai ona fa'aleleia ai le fa'atinoga. I le faʻataʻitaʻiga, e manaʻomia le faʻataʻitaʻiina e faʻavae i luga o faʻatulagaga maʻoti ma manaʻoga faʻatinoga, ma e tatau ona faia suʻega UL-94 e faʻamaonia ai le fua o le mumu.
