Moralo oa Foromo bakeng sa MCA le Aluminium Hypophosphite (AHP) ka Separator Coating for Flame Retardancy

Ho ipapisitsoe le litlhoko tse ikhethileng tsa mosebelisi bakeng sa liphahlo tsa karohano tse thibelang malakabe, litšobotsi tsaMelamine Cyanurate (MCA)leAluminium Hypophosphite (AHP)li sekasekoa ka tsela e latelang:

1. Ho lumellana le Slurry Systems

• MCA:
• Sistimi ea metsi:E hloka phetoho ea bokaholimo (mohlala, li-silane coupling agents kapa li-surfactants) ho ntlafatsa tšilafalo; ho seng joalo, ho ka etsahala agglomeration.
• Sistimi ea NMP:E ka 'na ea bontša ho ruruha ho fokolang ho li-solvents tsa polar (ho khothaletsoa: tekanyo ea ho ruruha ea teko ka mor'a ho qoelisoa ka matsatsi a 7).
• AHP:
• Sistimi ea metsi:Dispersibility e ntle, empa pH e tlameha ho laolwa (maemo a acidic a ka baka hydrolysis).
• Sistimi ea NMP:Botsitso bo phahameng ba lik'hemik'hale bo nang le kotsi e fokolang ea ho ruruha.
  Qetello:AHP e bonts'a tšebelisano e betere, athe MCA e hloka phetoho.

2. Ho Ikamahanya le Boemo ba Particle le Coating Process

• MCA:
• D50 ea pele: ~ 1–2 μm; e hloka ho sila (mohlala, ho sila lehlabathe) ho fokotsa boholo ba likaroloana, empa ho ka senya sebopeho sa eona se nang le lera, ho ama ts'ebetso e thibelang mollo.
• Ho lumellana ka mor'a ho sila ho tlameha ho netefatsoa (tebello ea SEM).
• AHP:
• D50 ea pele: Ka tloaelo ≤5 μm; ho sila ho D50 0.5 μm/D90 1 μm ho ka finyelloa (ho sila ho feteletseng ho ka baka slurry viscosity spikes).
  Qetello:MCA e na le maemo a betere a boholo ba likaroloana ka kotsi e tlase ea ts'ebetso.

3. Ho hanyetsa ho khomarela le Abrasion

• MCA:
• Polarity e tlase e lebisa ho se mamelle hantle le lifilimi tsa karohano tsa PE / PP; e hloka 5–10% ea li-binder tse thehiloeng ho acrylic (mohlala, PVDF-HFP).
• Coefficient e phahameng ea likhohlano e ka 'na ea hloka ho eketsa 0.5-1% nano-SiO₂ ho ntlafatsa ho hanyetsa ho apara.
• AHP:
• Lihlopha tsa hydroxyl tse ka holim'a metsi li theha maqhama a hydrogen le karohano, li ntlafatsa ho khomarela, empa li-binders tsa polyurethane tse 3-5% li ntse li hlokahala.
• Ho thatafala ho hoholo (Mohs ~ 3) ho ka baka tšenyo ea microparticle tlasa likhohlano tsa nako e telele (ho hloka tlhahlobo ea cyclic).
  Qetello:AHP e fana ka ts'ebetso e betere ka kakaretso empa e hloka ntlafatso ea binder.

4. Thermal Stability and Decomposition Properties

• MCA:
• Mocheso oa ho senyeha: 260-310 ° C; ha e khone ho hlahisa khase ho 120-150 ° C, e ka 'nang ea hlōleha ho thibela ho baleha ha mocheso.
• AHP:
• Mocheso oa ho senyeha: 280-310 ° C, hape ha o lekane bakeng sa tlhahiso ea khase e tlaase.
  Taba ea Bohlokoa:Ka bobeli li bola ka holim'a sebaka se lebeletsoeng (120-150 ° C).Litharollo:
• Hlahisa li-synergists tsa mocheso o tlase (mohlala, phosphorus e khubelu e nyenyane ea microencapsulated, sebaka sa ho bola: 150-200 ° C) kapa ammonium polyphosphate e fetotsoeng (APP, e koahetsoeng ho fetola ho bola ho 140-180 ° C).
• Moralo aMotsoako oa MCA/APP (karo-karolelano ea 6:4)ho matlafatsa tlhahiso ea khase ea mocheso o tlase oa APP + le thibelo ea lelakabe la khase ea MCA.

5. Electrochemical and Corrosion Resistance

• MCA:
• Electrochemically inert, empa melamine ea mahala e setseng (ho hloeka ≥99.5% e hlokahalang) e ka baka ho bola ha electrolyte.
• AHP:
• Litšila tsa asiti (mohlala, H₃PO₂) li tlameha ho fokotsoa (teko ea ICP: li-ion tsa tšepe ≤10 ppm) ho qoba ho potlakisa LiPF₆ hydrolysis.
  Qetello:Ka bobeli li hloka bohloeki bo phahameng (≥99%), empa MCA e bonolo ho e hloekisa.

Tlhahiso e Felletseng ea Tharollo

1. Khetho ea mantlha ea ho fokotsa mollo:

• Tse ratoang:AHP (e leka-lekaneng dispersibility / adhesion) + tlaase mocheso synergist (mohlala, 5% microencapsulated khubelu phosphorus).
• E 'ngoe:MCA e fetotsoeng (carboxyl-grafted for aqueous dispersion) + APP synergist.

1. Ntlafatso ea Ts'ebetso:

• Foromo ea seretse:AHP (90%) + polyurethane binder (7%) + moemeli oa ho kolobisa (BYK-346, 0.5%) + defoamer (2%).
• Li-parameter tsa ho sila:Leloala la lehlabathe le nang le lifaha tsa 0.3 mm ZrO₂, 2000 rpm, 2 h (sepheo sa D90 ≤1 μm).

1. Liteko tsa Netefatso:

• Ho senyeha ha mocheso:TGA (ho lahleheloa ke boima ba 'mele <1% ho 120 ° C / 2h; tlhahiso ea khase ho 150 ° C / 30min ka GC-MS).
• Ho tsitsa ha electrochemical:Tlhokomelo ea SEM kamora ho qoelisoa ka matsatsi a 30 ho 1M LiPF₆ EC/DMC ho 60°C.

Keletso ea ho Qetela

Ha ho MCA kapa AHP feela e fihlelang litlhoko tsohle. Atsamaiso e nyalisitsoenge eletswa:

• AHP (matrix)+phosphorus e khubelu ea microencapsulated (jenereithara ea khase ea mocheso o tlase)+nano-SiO₂(abrasion resistance).
• Apara le phahameng-adhesion aqueous resin (mohlala, acrylic-epoxy composite emulsion) 'me optimize holim'a phetolo bakeng sa boholo phatsa / hasane botsitso.
  Teko e eketsehilengho hlokahala ho netefatsa synergy ea thermal-electrochemical.
