Te Hoahoa Tātai mō te MCA me te Hypophosphite Konumohe (AHP) i roto i te Paninga Wehewehe hei Ārai i te Mura

Te Hoahoa Tātai mō te MCA me te Hypophosphite Konumohe (AHP) i roto i te Paninga Wehewehe hei Ārai i te Mura

I runga i ngā whakaritenga motuhake a te kaiwhakamahi mō ngā paninga wehewehe ātete-mura, ko ngā āhuatanga oMelamine Cyanurate (MCA)meKonumohe Hipofosita (AHP)ka tātarihia penei:

1. Hototahi ki ngā Pūnaha Para

• MCA:
• Ngā pūnaha wai:Me whakarerekē te mata (hei tauira, ngā kaihoko honohono silane, ngā surfactants rānei) hei whakapai ake i te horapa; ki te kore, ka puta pea te whakaemi.
• Ngā pūnaha NMP:Tērā pea ka kitea he pupuhi iti i roto i ngā whakarewa porotaka (e taunakitia ana: whakamātauria te tere pupuhi i muri i te rumakina mō ngā rā e 7).
• AHP:
• Ngā pūnaha wai:He pai te horapa, engari me whakahaere te pH (tērā pea ka puta te waikura i ngā āhuatanga waikawa).
• Ngā pūnaha NMP:He tino pumau te matū, he iti rawa te mōrearea pupuhi.
  Whakatau:He pai ake te hototahitanga o te AHP, engari me whakarerekē te MCA.

2. Te Rahi o te Matūriki me te Āheinga o te Tukanga Paninga

• MCA:
• D50 Taketake: ~1–2 μm; me huri (hei tauira, te mira onepu) hei whakaiti i te rahi o te matūriki, engari ka kino pea tōna hanganga paparanga, ka pā ki te whai huatanga o te ātete mura.
• Me manatoko te ōritetanga i muri i te huri (tirohanga SEM).
• AHP:
• D50 Taketake: I te nuinga o te wā ka taea te huri ki te D50 0.5 μm/D90 1 μm (tērā pea ka piki ake te matotoru o te paru mēnā ka huri nui rawa).
  Whakatau:He pai ake te urutau o te MCA ki te rahi o te matūriki, ā, he iti ake te mōrearea tukanga.

3. Ātete ki te Piri me te Ātete ki te Waro

• MCA:
• Nā te iti o te polarity ka ngoikore te piri ki ngā kiriata wehewehe PE/PP; me 5–10% ngā here kiriaku (hei tauira, PVDF-HFP).
• Nā te nui o te tauwehenga waku, me tāpiri pea te 0.5–1% nano-SiO₂ hei whakapai ake i te ātete ki te kakahu.
• AHP:
• Ka hanga hononga hauwai ngā rōpū hydroxyl o te mata ki te wehewehe, ka pai ake te piri, engari e hiahiatia tonutia ana he here polyurethane 3–5%.
• Mā te pakeke nui ake (Mohs ~3) ka heke pea ngā matūriki iti i raro i te waku roa (me whakamātautau huringa).
  Whakatau:He pai ake te mahi whānui a te AHP engari me arotau te here.

4. Te Pūmautanga o te Wera me ngā Āhuatanga Pirau

• MCA:
• Pāmahana pirau: 260–310°C; kāore e taea te whakaputa hau i te 120–150°C, ā, kāore pea e taea te pehi i te rerenga wera.
• AHP:
• Te pāmahana pirau: 280–310°C, kāore hoki i te rawaka mō te whakaputa hau i te pāmahana iti.
  Take Matua:Ka pirau ngā mea e rua i runga ake i te awhe ūnga (120–150°C).Ngā otinga:
• Whakauruhia ngā matū honohono pāmahana-iti (hei tauira, te whākawa whero kua whakakīia ki roto i te capsules iti, te awhe pirau: 150–200°C) te ammonium polyphosphate kua whakarerekētia rānei (APP, kua pania hei whakatika i te pirau ki te 140–180°C).
• Hoahoa heMCA/APP hiato (ōwehenga 6:4)hei whakamahi i te whakaputa hau pāmahana-iti a APP + te aukati mura āhua-hau a MCA.

5. Ātete Hikohiko me te Waikura

• MCA:
• Kāore e mahi ana i te hikohiko matū, engari ko te melamine kore utu toenga (e hiahiatia ana te parakore ≥99.5%) ka āwhina pea i te wetewete i ngā hikohiko.
• AHP:
• Me whakaiti i ngā poke waikawa (hei tauira, H₃PO₂) (whakamātautau ICP: ngā katote konganuku ≤10 ppm) kia kore ai e tere ake te waikura o LiPF₆.
  Whakatau:E rua ngā mea e hiahiatia ana he parakore teitei (≥99%), engari he māmā ake te pure i te MCA.

Whakaaro Whakaoti Whānui

1. Kōwhiringa Ārai Mura Matua:

• Pai ake:AHP (whakamarara taurite/piripiri) + kaiwhakakotahi pāmahana-iti (hei tauira, 5% te whākawa whero kua whakakīia ki roto i te capsules iti).
• Kōwhiringa kē:MCA whakarerekētia (kāpokepoke-carboxyl mō te marara wai) + APP synergist.

1. Arotautanga Tukanga:

• Tātai parai:AHP (90%) + here polyurethane (7%) + kaihoko whakamakuku (BYK-346, 0.5%) + kaiwhakakore huka (2%).
• Ngā tawhā huri:Mira onepu me ngā pītiti ZrO₂ 0.3 mm, 2000 rpm, 2 hāora (whāinga D90 ≤1 μm).

1. Ngā Whakamātautau Whakamana:

• Te pirau wera:TGA (te whakahekenga taumaha <1% i te 120°C/2h; te putanga hau i te 150°C/30min mā te GC-MS).
• Te pumau hikohiko:Te mātakitaki i te SEM i muri i te rumakina mō ngā rā 30 ki roto i te 1M LiPF₆ EC/DMC i te 60°C.

Taunakitanga Whakamutunga

Kāore a MCA, a AHP rānei e tutuki i ngā whakaritenga katoa.pūnaha ranue taunakihia ana:

• AHP (matrix)+te whākawa whero kua whakakīia ki roto i te kāpūkara iti (te kaihanga hau pāmahana iti)+nano-SiO₂(ātete ki te pakū).
• Tāpirihia ki tētahi kapia wai piri-teitei (hei tauira, te whakahuihuinga hiato kiriaku-epoxy) ka arotau i te whakarerekētanga o te mata mō te rahi o te matūriki/te pumau o te marara.
  Whakamātautau anōe hiahiatia ana hei whakamana i te mahi tahi o te wera me te hikohiko.
