Dhizaini yefomura yeMCA neAluminium Hypophosphite (AHP) muSeparator Coating yekudzivirira moto

Zvichienderana nezvinodiwa nemushandisi zvemachira ekudzivirira moto, hunhu hweMelamine Cyanurate (MCA)uyeAluminium Hypophosphite (AHP)zvinoongororwa seizvi:

1. Kuenderana neSlurry Systems

• MCA:
• Masisitimu emvura:Zvinoda kugadziriswa kwenzvimbo (semuenzaniso, zvinhu zvinobatanidza silane kana zvinhu zvinoshandisa ma surfactants) kuti zvisapararire; zvikasadaro, kuunganidzana kunogona kuitika.
• Masisitimu eNMP:Inogona kuratidza kuzvimba kudiki muzvinhu zvinonyungudutsa mvura (zvinokurudzirwa: edza kuzvimba mushure mekunyudzwa kwemazuva manomwe).
• AHP:
• Masisitimu emvura:Kupararira kwakanaka, asi pH inofanira kudzorwa (mamiriro ezvinhu ane acid anogona kukonzera hydrolysis).
• Masisitimu eNMP:Kugadzikana kwakanyanya kwemakemikari pasina njodzi yekuzvimba.
  Mhedziso:AHP inoratidza kushanda zviri nani, nepo MCA ichida kugadziriswa.

2. Kugona Kuchinjika paSaizi yeChidimbu uye Maitiro Ekugadzira

• MCA:
• D50 yekutanga: ~1–2 μm; inoda kukuyiwa (semuenzaniso, kugayiwa kwejecha) kuderedza saizi yezvidimbu, asi inogona kukanganisa chimiro chayo chakaiswa muzvikamu, zvichikanganisa kushanda zvakanaka kwemurazvo.
• Kufanana kwekushanda mushure mekukuya kunofanirwa kusimbiswa (SEM observation).
• AHP:
• D50 yekutanga: Kazhinji ≤5 μm; kukuya kusvika D50 0.5 μm/D90 1 μm kunogoneka (kukuya zvakanyanya kunogona kukonzera kusviba kwe slurry viscosity).
  Mhedziso:MCA ine hunyanzvi huri nani hwekuchinjika nehukuru hwezvinhu uye ine njodzi shoma yekushanda.

3. Kuramba Kunamatira uye Kuramba Kuora

• MCA:
• Kusanyatsobatana zvakanaka kwemafirimu ePE/PP; zvinoda 5–10% acrylic-based binders (semuenzaniso, PVDF-HFP).
• Kukwikwidzana kwakanyanya kunogona kudikanwa kuwedzera 0.5–1% nano-SiO₂ kuti iwedzere kuramba kupfeka.
• AHP:
• Mapoka ehydroxyl pamusoro anoumba zvisungo zvehydrogen nechikamu chinoparadzanisa, zvichivandudza kunamira, asi 3–5% polyurethane binders ichiri kudiwa.
• Kuomarara kwakanyanya (Mohs ~3) kunogona kukonzera kubuda kwe microparticle kana paine kukweshana kwenguva refu (zvinoda kuyedzwa kwecyclic).
  Mhedziso:AHP inoita kuti zvive nani asi inoda kugadziriswa kwema "binder".

4. Kugadzikana kwekupisa uye Hunhu hwekuora

• MCA:
• Tembiricha yekuora: 260–310°C; haigone kuburitsa gasi pa120–150°C, zvichigona kutadza kudzikamisa kupisa kunobva mumhepo.
• AHP:
• Kupisa kwekuora: 280–310°C, hazvikwaniwo kugadzira gasi rinopisa zvakanyanya.
  Nyaya Huru:Zvose zvinoora pamusoro penzvimbo yakatarwa (120–150°C).Mhinduro:
• Isa ma synergists anodziya zvishoma (semuenzaniso, microencapsulated red phosphorus, kuora kwenzvimbo: 150–200°C) kana modified ammonium polyphosphate (APP, yakaputirwa kuti igadzirise kuora kwenzvimbo kusvika 140–180°C).
• DhizainiMCA/APP composite (6:4 ratio)kushandisa kugadzirwa kwegasi reAPP rinopisa zvishoma + kudziviswa kwemurazvo wegesi weMCA.

5. Kuramba Kurapwa Nemagetsi Nengura

• MCA:
• Melamine isina simba remagetsi, asi yakasara isina chinhu (kuchena kunodiwa ≥99.5%) inogona kukonzera kuora kwe electrolyte.
• AHP:
• Kusvibiswa kweasidhi (semuenzaniso, H₃PO₂) kunofanira kuderedzwa (ICP test: metal ions ≤10 ppm) kudzivirira kukurumidza hydrolysis yeLiPF₆.
  Mhedziso:Zvese zvinoda kuchena kwakanyanya (≥99%), asi MCA iri nyore kuchenesa.

Chikumbiro Chemhinduro Yakakwana

1. Sarudzo Yekutanga Inodzivirira Murazvo:

• Zvinosarudzwa:AHP (kupararira/kunamatira kwakaringana) + synergist yekupisa kwakaderera (semuenzaniso, 5% microencapsulated red phosphorus).
• Zvimwe:MCA yakagadziriswa (yakaiswa mucarboxyl kuti iparadzirwe mumvura) + APP synergist.

1. Kugadzirisa Maitiro:

• Fomura yetsvina:AHP (90%) + polyurethane binder (7%) + weting agent (BYK-346, 0.5%) + defoamer (2%).
• Kukuya parameters:Chigayo chemajecha chine mabhora eZrO₂ e0.3 mm, 2000 rpm, maawa maviri (chinangwa D90 ≤1 μm).

1. Miedzo yekusimbisa:

• Kuora kwekupisa:TGA (kudzikira kwehuremu <1% pa 120°C/2awa; kuburitswa kwegasi pa 150°C/30min kuburikidza neGC-MS).
• Kugadzikana kwemakemikari emagetsi:Kuonekwa kweSEM mushure mekunyudzwa kwemazuva makumi matatu mu1M LiPF₆ EC/DMC pa60°C.

Kurudziro Yekupedzisira

MCA kana AHP chete hazvina kukwana zvese zvinodiwa.sisitimu yehybridinorayirwa:

• AHP (matrix)+phosphorus tsvuku yakavharirwa muzvikamu zvidiki (inogadzira gasi rinopisa zvishoma)+nano-SiO₂(kuramba kusviba).
• Batanidza ne resin yemvura ine glue yakakwira (semuenzaniso, acrylic-epoxy composite emulsion) uye gadzirisa kushanduka kwenzvimbo kuti saizi yezvikamu/kupararira kwayo igadzikane.
  Kuenderera mberi nekuyedzwazvinodiwa kuti pave nechokwadi chekuti thermal-electrochemical inoshanda pamwe chete.
