Moralo oa Foromo bakeng sa MCA le Aluminium Hypophosphite (AHP) ho Sekoahelo sa Karohano bakeng sa ho Fokotsa Mollo

Ho latela litlhoko tse khethehileng tsa mosebelisi bakeng sa liphahlo tse thibelang mollo, litšobotsi tsaMelamine Cyanurate (MCA)leAluminium Hypophosphite (AHP)li sekasekoa ka tsela e latelang:

1. Ho lumellana le Sistimi ea Slurry

• MCA:
• Mekhoa ea metsi:E hloka phetoho ea bokaholimo (mohlala, li-sylane coupling agents kapa li-surfactants) ho ntlafatsa ho qhalana ha tsona; ho seng joalo, ho ka etsahala hore ho be le ho kopana ha lintho.
• Litsamaiso tsa NMP:E ka 'na ea bontša ho ruruha ho honyenyane ka har'a metsoako ea polar (e khothaletsoa: leka sekhahla sa ho ruruha kamora ho qoelisoa ka matsatsi a 7).
• AHP:
• Mekhoa ea metsi:Ho qhalana ho hotle, empa pH e lokela ho laolwa (maemo a asiti a ka baka hydrolysis).
• Litsamaiso tsa NMP:Ho tsitsa ha lik'hemik'hale tse ngata ka kotsi e fokolang ea ho ruruha.
  Qetello:AHP e bonts'a ho lumellana ho betere, ha MCA e hloka phetoho.

2. Boholo ba Likaroloana le Mokhoa oa ho Koahela Ho Ikamahanya le Maemo

• MCA:
• D50 ea mantlha: ~1–2 μm; e hloka ho siloa (mohlala, ho siloa ha lehlabathe) ho fokotsa boholo ba likaroloana, empa e ka senya sebopeho sa eona se nang le mekhahlelo, ea ama bokhoni ba ho thibela malakabe.
• Ho tšoana ha ho sila ho lokela ho netefatsoa (tlhokomelo ea SEM).
• AHP:
• D50 ea mantlha: Hangata ≤5 μm; ho sila ho fihlela ho D50 0.5 μm/D90 1 μm hoa khoneha (ho sila ho feteletseng ho ka baka ho phahama ha viscosity ea lerōle).
  Qetello:MCA e na le bokgoni bo betere ba ho ikamahanya le boholo ba dikarolwana ka kotsi e tlase ya tshebetso.

3. Ho hanyetsa ho khomarela le ho abrasion

• MCA:
• Polarity e tlase e lebisa ho kgomareleng ho fokolang ha difilimi tsa karohano ya PE/PP; e hloka di-binder tse thehilweng ho acrylic tse 5–10% (mohlala, PVDF-HFP).
• Koefficient e phahameng ea khohlano e ka hloka ho eketsoa ha 0.5–1% nano-SiO₂ ho ntlafatsa ho hanyetsa ho tsofala.
• AHP:
• Lihlopha tsa hydroxyl tse holim'a metsi li theha maqhama a haedrojene le karohano, e leng se ntlafatsang ho khomarela, empa li-binder tsa polyurethane tse 3-5% li ntse li hlokahala.
• Ho thatafala ho hoholo (Mohs ~3) ho ka baka ho qhalana ha di-microparticle tlasa kgohlano e telele (ho hloka tlhahlobo ya potoloho).
  Qetello:AHP e fana ka tshebetso e betere ka kakaretso empa e hloka ntlafatso ya binder.

4. Botsitso ba Thempereichara le Thepa ea ho Bola

• MCA:
• Mocheso oa ho bola: 260–310°C; e ke ke ea hlahisa khase ho 120–150°C, e leng se ka 'nang sa hlōleha ho thibela ho foqoha ha mocheso.
• AHP:
• Mocheso oa ho bola: 280–310°C, hape ha oa lekana bakeng sa tlhahiso ea khase mochesong o tlase.
  Bothata ba Bohlokoa:Ka bobeli lia bola kaholimo ho sebaka seo li reretsoeng ho sona (120–150°C).Litharollo:
• Kenya di-synergists tse nang le mocheso o tlase (mohlala, phosphorus e khubelu e kentsoeng ka har'a microcapsulated, sebaka sa ho bola: 150–200°C) kapa modified ammonium polyphosphate (APP, e koahetsoeng ho lokisa ho bola ho 140–180°C).
• RalaMotsoako oa MCA/APP (karolelano ea 6:4)ho sebelisa tlhahiso ea khase ea mocheso o tlase ea APP + thibelo ea lelakabe la khase ea MCA.

5. Khanyetso ea Electrochemical le Tšenyo

• MCA:
• Melamine e sa sebetseng ka motlakase, empa e sa sebetseng e sa hlokeng letho (bohloeki ba ≥99.5% boa hlokahala) e ka baka ho bola ha electrolyte.
• AHP:
• Litšila tse nang le asiti (mohlala, H₃PO₂) li lokela ho fokotsoa (teko ea ICP: li-ion tsa tšepe ≤10 ppm) ho qoba ho potlakisa hydrolysis ea LiPF₆.
  Qetello:Ka bobeli li hloka bohloeki bo phahameng (≥99%), empa MCA e bonolo ho e hloekisa.

Tlhahiso e Felletseng ea Tharollo

1. Khetho ea Motheo ea ho Sitisa Mollo:

• E khethiloeng:AHP (ho qhalana/ho khomarela ho leka-lekaneng) + ho sebelisana ha mocheso o tlase (mohlala, 5% phosphorus e khubelu e kentsoeng ka har'a capsule).
• Mokhoa o mong:MCA e fetotsoeng (e kentsweng ka carboxyl bakeng sa ho hasana ha metsi) + APP synergist.

1. Ntlafatso ea Ts'ebetso:

• Foromo ea seretse:AHP (90%) + polyurethane binder (7%) + setlolo sa ho kolobisa (BYK-346, 0.5%) + defoamer (2%).
• Liparamente tsa ho sila:Selo sa lehlabathe se nang le dibead tsa ZrO₂ tsa 0.3 mm, 2000 rpm, dihora tse 2 (sepheo sa D90 ≤1 μm).

1. Liteko tsa Netefatso:

• Ho bola ha mocheso:TGA (ho theola boima ba 'mele <1% ho 120°C/2h; tlhahiso ea khase ho 150°C/30min ka GC-MS).
• Botsitso ba electrochemical:Ho shebella SEM ka mora ho qoelisoa ka matsatsi a 30 ho 1M LiPF₆ EC/DMC mochesong oa 60°C.

Tlhahiso ea ho Qetela

MCA kapa AHP ha li kopane le litlhoko tsohle.sistimi e kopanenge eletsoa:

• AHP (matrix)+phosphorus e khubelu e kentsoeng ka microcapsulated (jenereithara ea khase e mocheso o tlase)+nano-SiO₂(ho hanyetsa ho hohlora).
• Kopanya le resin e metsi e khomarelang haholo (mohlala, emulsion ea acrylic-epoxy composite) 'me u ntlafatse phetoho ea bokaholimo bakeng sa boholo ba likaroloana/botsitso ba ho hasana.
  Liteko tse lingho hlokahala ho netefatsa tšebelisano-'moho ea mocheso le motlakase.
