Nhazi usoro maka MCA na Aluminom Hypophosphite (AHP) na mkpuchi nkewa maka ire ọkụ.

Dabere na ihe onye ọrụ chọrọ maka ihe mkpuchi ọkụ-retardant separator mkpuchi, njirimara nkeMelamine Cyanurate (MCA)naAluminom Hypophosphite (AHP)A na-enyocha ya dị ka ndị a:

1. Ndakọrịta na Slurry Systems

• MCA:
• Sistemu mmiri:Na-achọ ngbanwe elu (dịka ọmụmaatụ, ndị na-ahụ maka njikọta silane ma ọ bụ ihe ndị na-ahụ maka mbara igwe) iji melite mgbasa; ma ọ bụghị ya, agglomeration nwere ike ime.
• Sistemụ NMP:Nwere ike igosipụta ntakịrị ọzịza na ihe mgbaze pola (a tụrụ aro: nwalee ọzịza ọzịza mgbe imikpuchara ụbọchị asaa).
• AHP:
• Sistemu mmiri:Ezi dispersibility, mana pH ga-achịkwa (ọnọdụ acid nwere ike ime ka hydrolysis).
• Sistemụ NMP:Nkwụsi ike kemịkalụ dị elu yana ihe egwu ọzịza pere mpe.
  Mmechi:AHP na-egosi ndakọrịta ka mma, ebe MCA chọrọ mgbanwe.

2. Oke urughuru na mkpuchi usoro nnabata

• MCA:
• Mbụ D50: ~ 1-2 μm; na-achọ egweri (dịka ọmụmaatụ, igwe igwe aja) iji belata nha urughuru, mana nwere ike mebie nhazi ya, na-emetụta arụmọrụ ọkụ na-ere ọkụ.
• A ga-enyocharịrị ịdị n'otu mgbe egwerichara (nleba anya SEM).
• AHP:
• Mbụ D50: Na-emekarị ≤5 μm; egweri na D50 0.5 μm/D90 1 μm bụ nke a ga-enweta (oke egweri nwere ike ime ka slurry viscosity spikes).
  Mmechi:MCA nwere mma urughuru size adaptability na ala usoro ize ndụ.

3. Adhesion na Abrasion Resistance

• MCA:
• Polarity dị ala na-eduga na nrapanye na-adịghị mma na ihe nkiri PE / PP nkewa; na-achọ 5–10% ihe nkedo dabere na acrylic (dịka, PVDF-HFP).
• Ọnụọgụ esemokwu dị elu nwere ike ịchọ ịgbakwụnye 0.5-1% nano-SiO₂ iji melite nguzogide eyi.
• AHP:
• Otu ìgwè hydroxyl dị n'elu na-emepụta njikọ hydrogen na onye nkesa, na-eme ka adhesion dịkwuo mma, mana 3-5% polyurethane binders ka chọrọ.
• Isi ike dị elu (Mohs ~ 3) nwere ike ime ka mbelata microparticle n'okpuru esemokwu ogologo oge (chọrọ nyocha cyclic).
  Mmechi:AHP na-enye arụmọrụ n'ozuzu ya ka mma mana ọ chọrọ njikarịcha ihe nkedo.

4. Thermal Stability na Decomposition Properties

• MCA:
• Ọnọdụ ire ere: 260-310 ° C; enweghị ike iwepụta gas na 120-150 Celsius C, nke nwere ike ghara ịkwụsị ikpo ọkụ ọkụ.
• AHP:
• Okpomọkụ ire ere: 280-310 ° C, ezughịkwa maka ọgbọ gas dị ala.
  Isi okwu:Ha abụọ na-emebi emebi n'elu ebe ebumnuche (120-150ºC).Ngwọta:
• Webata synergists dị ala (dịka ọmụmaatụ, microencapsulated red phosphorus, decomposition range: 150-200°C) ma ọ bụ ammonium polyphosphate gbanwetụrụ (APP, mkpuchi iji dozie ire ere na 140-180 ° C).
• Chepụta iheNgwakọta MCA/APP (oke 6:4)iji kwalite ọgbọ gas na-ekpo ọkụ dị ala nke APP + mgbochi ọkụ na-ekpo ọkụ nke MCA.

5. Electrochemical na corrosion Resistance

• MCA:
• Electrochemically inert, ma melamine nke fọdụrụ n'efu (ịdị ọcha ≥99.5% achọrọ) nwere ike ịkpata ire ere electrolyte.
• AHP:
• A ghaghị ibelata ihe adịghị acidic (dịka ọmụmaatụ, H₃PO₂) (nnwale ICP: ion metal ≤10 ppm) iji zere ịgba ọsọ LiPF₆ hydrolysis.
  Mmechi:Ha abụọ chọrọ ịdị ọcha dị elu (≥99%), mana MCA dị mfe ime ka ọ dị ọcha.

Ngwọta zuru oke

1. Nhọrọ Nkwụghachi ọkụ nke Isi:

• Nke kacha mma:AHP (mgbasasa / nrapanye kwesịrị ekwesị) + synergist dị ala (dịka ọmụmaatụ, 5% microencapsulated red phosphorus).
• Nhọrọ:MCA emegharịrị (carboxyl-anyado maka mgbasa mmiri) + APP synergist.

1. Nkwalite usoro:

• Usoro slurry:AHP (90%) + polyurethane binder (7%) + onye na-ahụ maka mmiri mmiri (BYK-346, 0.5%) + defoamer (2%).
• Paragraf na-egweri:Igwe igwe igwe nwere 0.3 mm ZrO₂ beads, 2000 rpm, 2 h (ezubere D90 ≤1 μm).

1. Nnwale nkwado:

• ire ere ọkụ:TGA (oke ibu <1% na 120°C/2h; mmepụta gas na 150°C/30min site na GC-MS).
• Nkwụsi ike nke electrochemical:Nlebanya SEM ka imikpu ụbọchị 30 na 1M LiPF₆ EC/DMC na 60°C.

Nkwanye ikpeazụ

Ma MCA ma ọ bụ AHP naanị emezughị ihe niile achọrọ. Angwakọ usoroa na-adụ ọdụ:

• AHP (matrix)+microencapsulated red phosphorus (gas generator na-ekpo ọkụ dị ala)+nano-SiO₂(nguzogide abrasion).
• Jikọọ na a elu-adhesion aqueous resin (eg, acrylic-epoxy composite emulsion) na ebuli elu mgbanwe maka urughuru size / dispersion kwụsie ike.
  Nnwale ọzọdị mkpa iji kwado mmekọrịta thermal-electrochemical synergy.
