Apẹrẹ Fọọmu fun MCA ati Aluminiomu Hypophosphite (AHP) ni Aso Iyapa fun Idaduro Ina

Da lori awọn ibeere kan pato ti olumulo fun awọn ideri iyapa ina, awọn abuda tiMelamine Cyanurate (MCA)atiAluminiomu Hypophosphite (AHP)ti wa ni atupale bi wọnyi:

1. Ibamu pẹlu Slurry Systems

• MCA:
• Awọn ọna ṣiṣe olomi:Nbeere iyipada oju-aye (fun apẹẹrẹ, awọn aṣoju isọpọ silane tabi awọn ohun-ọṣọ) lati mu ilọsiwaju pọ si; bibẹkọ ti, agglomeration le ṣẹlẹ.
• Awọn ọna ṣiṣe NMP:Le ṣe afihan wiwu diẹ ninu awọn ohun mimu pola (a ṣeduro: idanwo oṣuwọn wiwu lẹhin immersion ọjọ meje).
• AHP:
• Awọn ọna ṣiṣe olomi:Iyatọ ti o dara, ṣugbọn pH gbọdọ wa ni iṣakoso (awọn ipo ekikan le fa hydrolysis).
• Awọn ọna ṣiṣe NMP:Iduroṣinṣin kemikali giga pẹlu eewu wiwu kekere.
  Ipari:AHP ṣe afihan ibaramu to dara julọ, lakoko ti MCA nilo iyipada.

2. Patiku iwọn ati ki o bo ilana Adapability

• MCA:
• Atilẹba D50: ~ 1-2 μm; nilo lilọ (fun apẹẹrẹ, lilọ iyanrin) lati dinku iwọn patiku, ṣugbọn o le ba eto siwa rẹ jẹ, ti o ni ipa ṣiṣe ṣiṣe ti ina.
• Aṣọṣọkan lilu lẹhin-lilọ gbọdọ jẹri (akiyesi SEM).
• AHP:
• Atilẹba D50: Ni deede ≤5 μm; lilọ si D50 0.5 μm/D90 1 μm jẹ aṣeyọri (lilọ pupọ le fa awọn spikes viscosity slurry).
  Ipari:MCA ni o ni dara patiku iwọn adaptability pẹlu kekere ilana ewu.

3. Adhesion ati Abrasion Resistance

• MCA:
• Kekere polarity nyorisi si ko dara adhesion pẹlu PE / PP separator fiimu; nbeere 5–10% akiriliki-orisun binders (fun apẹẹrẹ, PVDF-HFP).
• Olusọdipúpọ edekoyede giga le ṣe pataki fifi 0.5–1% nano-SiO₂ kun lati mu imudara yiya duro.
• AHP:
• Awọn ẹgbẹ hydroxyl dada ṣe awọn ifunmọ hydrogen pẹlu oluyapa, imudara adhesion, ṣugbọn 3–5% polyurethane binders tun nilo.
• Lile ti o ga julọ (Mohs ~ 3) le fa itusilẹ microparticle labẹ ija gigun (nilo idanwo gigun kẹkẹ).
  Ipari:AHP nfunni ni iṣẹ ṣiṣe gbogbogbo ti o dara julọ ṣugbọn nilo iṣapeye dinder.

4. Gbona Iduroṣinṣin ati Ibajẹ Awọn ohun-ini

• MCA:
• Iwọn otutu ibajẹ: 260-310 ° C; ko le ṣe ina gaasi ni 120-150°C, ti o le kuna lati dinku imunirun igbona.
• AHP:
• Iwọn otutu ibajẹ: 280-310 ° C, tun ko to fun iran gaasi iwọn otutu kekere.
  Oro koko:Mejeeji ti bajẹ loke ibiti ibi-afẹde (120-150°C).Awọn ojutu:
• Ṣe afihan awọn amuṣiṣẹpọ iwọn otutu kekere (fun apẹẹrẹ, irawọ owurọ pupa microencapsulated, ibiti o ti bajẹ: 150-200 ° C) tabi ammonium polyphosphate (APP, ti a bo lati ṣatunṣe ibajẹ si 140-180 ° C).
• Ṣe apẹrẹ kanÀkópọ̀ MCA/APP (6:4 ìpín)lati mu iran gaasi iwọn otutu kekere ti APP + idinamọ ina-fase gaasi MCA.

5. Electrochemical ati Ipata Resistance

• MCA:
• Electrochemically inert, ṣugbọn melamine ọfẹ ti o ṣẹku (mimọ ≥99.5% ti o nilo) le jẹ ki ibajẹ elekitiroti jẹ.
• AHP:
• Awọn impurities ekikan (fun apẹẹrẹ, H₃PO₂) gbọdọ dinku (idanwo ICP: awọn ions irin ≤10 ppm) lati yago fun isare LiPF₆ hydrolysis.
  Ipari:Mejeeji nilo mimọ giga (≥99%), ṣugbọn MCA rọrun lati sọ di mimọ.

Okeerẹ Solusan igbero

1. Asayan Idaduro Ina akọkọ:

• Ayanfẹ:AHP (iwọntunwọnsi dispersibility/adhesion) + amuṣiṣẹpọ iwọn otutu kekere (fun apẹẹrẹ, 5% microencapsulated pupa irawọ owurọ).
• Omiiran:MCA ti a ṣe atunṣe (carboxyl-tirun fun pipinka olomi) + APP amuṣiṣẹpọ.

1. Imudara ilana:

• Ilana Slurry:AHP (90%) + polyurethane binder (7%) + oluranlowo tutu (BYK-346, 0.5%) + defoamer (2%).
• Awọn paramita lilọ:Iyanrin ọlọ pẹlu 0.3 mm ZrO₂ ilẹkẹ, 2000 rpm, 2 h (afojusun D90 ≤1 μm).

1. Awọn Idanwo Ifọwọsi:

• Jije jijo gbona:TGA (pipadanu iwuwo <1% ni 120°C/2h; iṣelọpọ gaasi ni 150°C/30min nipasẹ GC-MS).
• Iduroṣinṣin elekitironi:Akiyesi SEM lẹhin immersion-ọjọ 30 ni 1M LiPF₆ EC/DMC ni 60°C.

Iṣeduro ipari

Bẹni MCA tabi AHP nikan ko pade gbogbo awọn ibeere. Aarabara etoni imọran:

• AHP (matrix)+irawọ owurọ pupa microencapsulated (olupilẹṣẹ gaasi iwọn otutu kekere)+nano-SiO₂(abrasion resistance).
• Papọ pẹlu resini olomi ti o ga-giga (fun apẹẹrẹ, emulsion composite acrylic-epoxy) ati ki o mu iyipada dada dara fun iwọn patiku / iduroṣinṣin pipinka.
  Idanwo siwaju siini a nilo lati fọwọsi amuṣiṣẹpọ itanna-ina.
