Hoahoa Tātai mo te MCA me te Aluminum Hypophosphite (AHP) i roto i te paninga Wehewehe mo te Whakamutunga mura.

Hoahoa Tātai mo te MCA me te Aluminum Hypophosphite (AHP) i roto i te paninga Wehewehe mo te Whakamutunga mura.

I runga i nga whakaritenga motuhake a te kaiwhakamahi mo nga paninga whakawehe mura, nga ahuatanga o teMelamine Cyanurate (MCA)aKonumohe Hypophosphite (AHP)ka tātarihia penei:

1. Hototahi ki nga Pūnaha Slurry

• MCA:
• Pūnaha wai:Me whakarerekē te mata (hei tauira, he maataki hono silane, surfactant ranei) hei whakapai ake i te marara; ki te kore, ka tupu pea te agglomeration.
• Nga punaha NMP:Ka whakaatu pea i te pupuhi iti i roto i nga whakarewa polar (e taunakitia ana: whakamatauria te tere o te pupuhi i muri i te rukutanga 7-ra).
• AHP:
• Pūnaha wai:He pai te whakamararatanga, engari me whakahaere te pH (kei te whakamaarama te waiwao ma te waikawa).
• Nga punaha NMP:He nui te pumau matū me te iti o te mate te pupuhi.
  Whakamutunga:Ko te AHP e whakaatu ana i te pai ake o te hototahitanga, ko te MCA me whakarereke.

2. Te Rahi Matūriki me te Whakakikorua Tukanga Te Urutau

• MCA:
• D50 Taketake: ~1–2 μm; me huri (hei tauira, te mira kirikiri) hei whakaiti i te rahi o te matūriki, engari ka pakaru pea tona hanganga paparanga, ka pa te pai o te mura.
• Me whakamanahia te riterite i muri i te huri huri (SEM observation).
• AHP:
• D50 Taketake: Ko te tikanga ≤5 μm; ko te huri ki D50 0.5 μm/D90 1 μm ka taea (ka kaha te huri oro ki te whakakorikori i te slurry viscosity titaha).
  Whakamutunga:He pai ake te urutau o te matūriki o te MCA me te iti ake o te tupono o te tukanga.

3. Adhesion me Abrasion Ātete

• MCA:
• Ko te polarity iti e arai ana ki te whakauru kino ki nga kiriata wehewehe PE / PP; e hiahia ana kia 5–10% nga here kiriaku (hei tauira, PVDF-HFP).
• Ko te whakarea waku teitei pea me taapiri te 0.5-1% nano-SiO₂ hei whakapai ake i te aukati kakahu.
• AHP:
• Ko nga roopu hydroxyl mata e hanga ana i nga here hauwai me te whakawehe, hei whakapai ake i te piri, engari me 3-5% nga here polyurethane kei te hiahia tonu.
• Ko te kaha ake o te pakeke (Mohs ~3) ka heke te matūriki moroiti i raro i te waku roa (me whakamatau i te hurihanga).
  Whakamutunga:He pai ake te mahi a te AHP engari me arotau te here.

4. Ngaaaahua Ngaaaahua me nga Ahuatanga Pito

• MCA:
• Te pāmahana whakapoapoa: 260–310°C; e kore e taea te whakaputa hau i te 120–150°C, ka kore pea e pehi i te rerenga waiariki.
• AHP:
• Te paemahana pirau: 280–310°C, he iti hoki mo te hanga hau wera iti.
  Take Matua:Ka pirau nga mea e rua ki runga ake i te awhe whainga (120–150°C).Rongoā:
• Whakauruhia nga kaitoi-whakaritenga iti (hei tauira, te ūkuikui whero microencapsulated, te awhe pirau: 150–200°C) te haukinia polyphosphate ranei (APP, kua pania ki te whakatika i te pirau ki te 140–180°C).
• Hoahoa heMCA/APP hiato (6:4 ōwehenga)ki te whakamahi i te whakangao hau iti-mahana a APP + te aukati mura o te hau-waa MCA.

5. Te Maama Hiko me te Waikura

• MCA:
• He koretake te hiko, engari ko te toenga melamine koreutu (te ma ≥99.5% e hiahiatia ana) ka taea te whakakorikori i te pirau hiko.
• AHP:
• Ko nga poke waikawa (hei tauira, H₃PO₂) me whakaitihia (whakamatautau ICP: katote whakarewa ≤10 ppm) kia kore ai e whakatere i te LiPF₆ hydrolysis.
  Whakamutunga:Ko nga mea e rua e hiahia ana kia tino parakore (≥99%), engari he ngawari ake te purei a MCA.

Kaupapa Whakataunga Matawhānui

1. Tīpakonga Whakamutunga Mua Tuatahi:

• Manakohia:AHP (taurite te whakamararatanga/apiri) + te whakahiato i te pāmahana iti (hei tauira, 5% te ūkuikui whero microencapsulated).
• He rereke:MCA whakarerekē (carboxyl-honohia mo te whakamararatanga wai) + APP synergist.

1. Arotautanga Tukanga:

• tātai slurry:AHP (90%) + polyurethane binder (7%) + wetting agent (BYK-346, 0.5%) + defoamer (2%).
• Tawhā huri:Te mira kirikiri me nga pirepire 0.3 mm ZrO₂, 2000 rpm, 2 haora (te whaainga D90 ≤1 μm).

1. Whakamātautau Whakamana:

• Te waiariki pirau:TGA (te mate taimaha <1% i te 120 ° C / 2h; te whakaputa hau i te 150 ° C / 30min ma te GC-MS).
• Pumautanga Hiko:Te kitenga SEM i muri i te 30-ra te rumaki ki te 1M LiPF₆ EC/DMC i te 60°C.

Taunakitanga Whakamutunga

Ko te MCA me te AHP anake e tutuki nga whakaritenga katoa. Apūnaha ranuka tohutohuhia:

• AHP (poupou)+ūkuikui whero microencapsulated (whakaputa hau-mahana-iti)+nano-SiO₂(ātete abrasion).
• Whakanohia ki te kapia wai-nui (hei tauira, te whakaehunga hiato kiriaku-epoxy) me te arotau i te whakarereketanga o te mata kia pai ai te rahi matūriki/te marara.
  He whakamatautau anoe hiahiatia ana hei whakamana i te whakakotahitanga o te waiariki-hiko.
