UYilo lweFomula ye-MCA kunye ne-Aluminiyam Hypophosphite (AHP) kwiSahluli soMtyalo wokuRetada komlilo

Ngokusekwe kwiimfuno ezikhethekileyo zomsebenzisi zokwahlula isahlukanisi esinqanda amadangatye, iimpawu zeIMelamine Cynurate (MCA)kwayeIAluminiyam Hypophosphite (AHP)zicazululwa ngolu hlobo lulandelayo:

1. Ukuhambelana neeNkqubo zeSlurry

• I-MCA:
• Iinkqubo zamanzi:Ifuna ukuguqulwa komphezulu (umzekelo, i-silane coupling agents okanye i-surfactants) ukuphucula ukusasazeka; kungenjalo, i-agglomeration ingenzeka.
• Iinkqubo ze-NMP:Ingabonisa ukuvuvukala okuncinci kwi-solvents ye-polar (kucetyiswa: ukuvavanya izinga lokuvuvukala emva kokucwiliswa kweentsuku ezi-7).
• AHP:
• Iinkqubo zamanzi:I-dispersibility elungileyo, kodwa i-pH kufuneka ilawulwe (iimeko ze-asidi zinokubangela i-hydrolysis).
• Iinkqubo ze-NMP:Ukuzinza okuphezulu kweekhemikhali kunye nomngcipheko omncinci wokuvuvukala.
  Isiphelo:I-AHP ibonisa ukuhambelana okungcono, ngelixa i-MCA idinga ukulungiswa.

2. Ubungakanani beNgxelo kunye neNkqubo yokuNxibelela uKuguquguquka

• I-MCA:
• I-D50 yoqobo: ~1–2 μm; ifuna ukucola (umzekelo, ukucola isanti) ukunciphisa ubungakanani bamasuntswana, kodwa kusenokonakalisa ulwakhiwo lwayo, nto leyo echaphazela ukusebenza kakuhle kwedangatye.
• Ukufana kwasemva kokusila kufuneka kuqinisekiswe (uqwalaselo lwe-SEM).
• AHP:
• I-D50 yoqobo: Ngokuqhelekileyo ≤5 μm; ukugaya ukuya ku-D50 0.5 μm/D90 1 μm iyafezekiswa (ukusila ngokugqithisileyo kunokubangela i-slurry viscosity spikes).
  Isiphelo:I-MCA inobungakanani obungcono bokuguquguquka kunye nomngcipheko ophantsi wenkqubo.

3. Ukuncamathela kunye noKuxhathisa i-Abrasion

• I-MCA:
• I-polarity ephantsi ikhokelela ekubambeni kakubi kunye neefilimu ze-PE / PP zokwahlula; ifuna i-5-10% ye-acrylic-based binders (umzekelo, i-PVDF-HFP).
• I-coefficient ye-friction ephezulu ingadinga ukongeza i-0.5-1% ye-nano-SiO₂ ukuphucula ukuxhathisa ukunxiba.
• AHP:
• Amaqela e-hydroxyl angaphezulu enza iibhondi ze-hydrogen kunye ne-separator, ukuphucula ukunamathela, kodwa i-3-5% i-polyurethane binders isadingeka.
• Ubulukhuni obuphezulu (i-Mohs ~ 3) bunokubangela ukuchithwa kwe-microparticle phantsi kwe-friction ixesha elide (idinga uvavanyo lwe-cyclic).
  Isiphelo:I-AHP ibonelela ngokusebenza okungcono xa iyonke kodwa ifuna ukwenziwa kwe-binder.

4. Ukuzinza kweThermal kunye neePropati zokuBola

• I-MCA:
• Iqondo lokushisa lokubola: 260-310 ° C; ayikwazi ukuvelisa igesi kwi-120-150 ° C, enokuthi ingakwazi ukucinezela i-thermal runaway.
• AHP:
• Iqondo lokushisa lokubola: i-280-310 ° C, nayo ayinakwanela ukuveliswa kwegesi ephantsi.
  Umba oPhambili:Zombini zibola ngaphezu koluhlu olujoliswe kuyo (120-150 ° C).Izisombululo:
• Yazisa ama-synergists aphantsi kweqondo lokushisa (umzekelo, i-phosphorus ebomvu ye-microencapsulated, uluhlu lokubola: 150-200 ° C) okanye i-ammonium polyphosphate elungisiweyo (i-APP, ifakwe ukulungelelanisa ukubola kwi-140-180 ° C).
• Yila iI-MCA/APP indibaniselwano (6:4 umlinganiselo)ukonyusela i-APP yokuvelisa irhasi yobushushu obuphantsi + i-MCA's gas-class inhibition flame.

5. Electrochemical and Corrosion Resistance

• I-MCA:
• I-Electrochemically inert, kodwa i-melamine yamahhala eseleyo (ubunyulu ≥99.5% efunekayo) inokubangela ukubola kwe-electrolyte.
• AHP:
• Ukungcola kwe-Acidic (umz., H₃PO₂) kufuneka kuncitshiswe (uvavanyo lwe-ICP: ii-ion zetsimbi ≤10 ppm) ukuphepha ukukhawuleza kwe-LiPF₆ hydrolysis.
  Isiphelo:Zombini zifuna ukucoceka okuphezulu (≥99%), kodwa i-MCA kulula ukuyihlambulula.

Isindululo sesisombululo esiBanzi

1. UKhetho olungundoqo lokubuyiswa komlilo:

• Ekhethwayo:I-AHP (i-dispersibility / i-adhesion elinganayo) + i-synergist yobushushu obuphantsi (umzekelo, i-5% ye-phosphorus ebomvu ye-microencapsulated).
• Enye indlela:I-MCA elungisiweyo (i-carboxyl-grafted for aqueous dispersion) + APP synergist.

1. UPhuculo lweNkqubo:

• Ifomula yoludaka:I-AHP (90%) + i-polyurethane binder (7%) + i-arhente yokumanzisa (BYK-346, 0.5%) + i-defoamer (2%).
• Iiparamitha zokugaya:Ilitye leSanti kunye ne-0.3 mm ZrO₂ ubuhlalu, i-2000 rpm, i-2 h (i-target D90 ≤1 μm).

1. Iimvavanyo zoQinisekiso:

• Ukubola kobushushu:I-TGA (ukulahlekelwa kwesisindo <1% kwi-120 ° C / 2h; ukukhutshwa kwegesi kwi-150 ° C / 30min nge-GC-MS).
• Uzinzo lwe-Electrochemical:Ukuqwalaselwa kwe-SEM emva kokuntywiliselwa kweentsuku ezingama-30 kwi-1M LiPF₆ EC/DMC kwi-60 ° C.

Isindululo sokugqibela

Ayiyiyo i-MCA okanye i-AHP iyodwa ehlangabezana nazo zonke iimfuno. Ainkqubo hybriduyacetyiswa:

• AHP (matrix)+i-microencapsulated ebomvu ye-phosphorus (ijenereyitha yegesi yobushushu obuphantsi)+nano-SiO₂(ukuxhathisa ukukrazuka).
• Dibanisa ne-high-adhesion aqueous resin (umzekelo, i-acrylic-epoxy composite emulsion) kunye nokwandisa ukuguqulwa komphezulu we-particle size / dispersion stability.
  Uvavanyo olongezelelweyoiyadingeka ukuze kuqinisekiswe i-thermal-electrochemical synergy.
