Igishushanyo cya formula cya MCA na Aluminium Hypophosphite (AHP) mu gusiga irangi ritandukanye kugira ngo umuriro ukomeze guhagarara

Hashingiwe ku byo umukoresha akeneye byihariye ku byerekeye irangi ritandukanya umuriro, imiterere yaMelamine Cyanurate (MCA)naHypophosfite ya Aluminium (AHP)Bisesengurwa ku buryo bukurikira:

1. Guhuza na sisitemu z'ubushyuhe

• MCA:
• Sisitemu z'amazi:Bisaba guhindura ubuso (urugero, ibikoresho byo guhuza silane cyangwa surfactants) kugira ngo byongere ubushobozi bwo gukwirakwira; bitabaye ibyo, guhurirana bishobora kubaho.
• Sisitemu za NMP:Ishobora kubyimba gato mu bintu biyungurura amazi (byasabwaga: gerageza kubyimba nyuma yo kwibiza mu mazi iminsi 7).
• AHP:
• Sisitemu z'amazi:Uburyo bwo gukwirakwiza neza, ariko pH igomba kugenzurwa (imiterere y’aside ishobora gutera hydrolysis).
• Sisitemu za NMP:Ubudahangarwa bwinshi bw'imiti kandi nta ngaruka mbi zo kubyimba.
  Umwanzuro:AHP igaragaza imikoranire myiza, mu gihe MCA isaba impinduka.

2. Ingano y'uduce tw'ibice n'uburyo bwo gutwikira bihinduka

• MCA:
• D50 y'umwimerere: ~ 1–2 μm; isaba gusya (urugero, gusya umucanga) kugira ngo igabanye ingano y'uduce, ariko ishobora kwangiza imiterere yayo, bigatera ingaruka ku buryo umuriro udakora neza.
• Uburinganire bw'ikoreshwa nyuma yo gusya bugomba kwemezwa (SEM observation).
• AHP:
• D50 y'umwimerere: Ubusanzwe ≤5 μm; gusya kugeza kuri D50 0.5 μm/D90 1 μm birashoboka (gusya cyane bishobora gutera ubushyuhe bwinshi).
  Umwanzuro:MCA ifite ubushobozi bwo kwihutisha ingano y'uduce duto kandi ingaruka zo gukora ibintu zikaba nke.

3. Gufata no kurwanya kwangirika

• MCA:
• Polarité nkeya ituma habaho gufatana nabi na PE/PP separator films; bisaba 5–10% by'ibifunga bishingiye kuri acrylic (urugero, PVDF-HFP).
• Igipimo cyo hejuru cyo gukururana gishobora gusaba ko hongerwamo 0.5–1% nano-SiO₂ kugira ngo hongerwe ubushobozi bwo kudashira.
• AHP:
• Amatsinda ya hydroxyl yo ku buso akora imigozi ya hydrogen hamwe n'icyuma gitandukanya, birushaho kunoza gufatana, ariko haracyakenewe imigozi ya polyurethane ingana na 3–5%.
• Ubukana bwinshi (Mohs ~ 3) bushobora gutuma uduce duto dutakaza uduce duto tw’umubiri bitewe n’ubukana bw’igihe kirekire (bisaba isuzuma ry’imikorere y’umubiri).
  Umwanzuro:AHP itanga imikorere myiza muri rusange ariko isaba kunoza uburyo bwo gukoresha binder.

4. Imiterere y'ubushyuhe n'uburyo bwo kubora

• MCA:
• Ubushyuhe bwo kubora: 260–310°C; ntishobora gutanga umwuka kuri 120–150°C, bishobora kunanirwa guhagarika ubushyuhe bukabije.
• AHP:
• Ubushyuhe bwo kubora: 280–310°C, kandi ntibuhagije ku ikoreshwa rya gaze mu bushyuhe buke.
  Ikibazo cy'ingenzi:Byombi birabora hejuru y’aho bigeze (120–150°C).Ibisubizo:
• Shyiramo imiti ikoresha ubushyuhe buke (urugero: fosifore itukura ya microencapsulated, ikoreshwa mu kubora: 150–200°C) cyangwa polyphosphate ya ammonium yahinduwe (APP, ipfundikiye kugira ngo ibore kugeza kuri 140–180°C).
• IgishushanyoMCA/APP ivanze (igipimo cya 6:4)gukoresha uburyo bwa APP bwo kubyaza imyuka ubushyuhe buke + uburyo bwa MCA bwo gukumira umuriro uterwa na gaze.

5. Ubudahangarwa bw'amashanyarazi n'ubudahangarwa bw'inkongi

• MCA:
• Melamine idakora neza mu buryo bw'amashanyarazi, ariko isigaye idafite amashanyarazi (ubuziranenge ≥99.5% bukenewe) ishobora gutuma electrolyte ibora.
• AHP:
• Imyanda iterwa na aside (urugero, H₃PO₂) igomba kugabanywa (ICP test: metal ions ≤10 ppm) kugira ngo hirindwe kwihutisha LiPF₆ hydrolysis.
  Umwanzuro:Byombi bisaba isuku nyinshi (≥99%), ariko MCA yoroshye kuyisukura.

Igitekerezo cyuzuye cy'umuti

1. Amahitamo y'ibanze y'ibidakoresha umuriro:

• Byakunzwe:AHP (uburyo bwo gutatana/gufata neza) + uburyo bwo guhuza ubushyuhe buri hasi (urugero, 5% ya fosifore itukura ifunze neza).
• Ubundi buryo:MCA yahinduwe (yashyizwemo karubokisili kugira ngo ikwirakwizwe mu mazi) + APP synergist.

1. Kunoza Imikorere:

• Ifuru y'urusenda:AHP (90%) + polyurethane binder (7%) + ikintu gitanga amazi (BYK-346, 0.5%) + defoamer (2%).
• Ibipimo byo gusya:Urusyo rw'umucanga rufite amasaro ya 0.3 mm ZrO₂, 2000 rpm, amasaha 2 (target D90 ≤1 μm).

1. Ibizamini byo kwemeza:

• Gushonga kw'ubushyuhe:TGA (kugabanya ibiro <1% kuri 120°C/2h; gazi isohoka kuri 150°C/30min binyuze kuri GC-MS).
• Gukomera kw'amashanyarazi:Kwitegereza SEM nyuma yo kwinjizwa mu 1M LiPF₆ EC/DMC ku bushyuhe bwa 60°C.

Icyifuzo cya nyuma

Nta na kimwe muri MCA cyangwa AHP cyujuje ibisabwa byose.sisitemu y'ibihuzwaigirwa inama:

• AHP (matrix)+fosifore itukura ifunze neza (imashini itanga gaze mu bushyuhe buke)+nano-SiO₂(kwirinda kwangirika kw'imitsi).
• Huza na resin y'amazi ifite ubushobozi bwo gufata neza (urugero, emulsion ya acrylic-epoxy composite) kandi wongere uburyo bwo guhindura ubuso kugira ngo ingano y'uduce/ikwirakwira ry'ibintu rikomeze gukomera.
  Isuzuma ryinyongerabirakenewe kugira ngo hemezwe ubufatanye hagati y’ubushyuhe n’amashanyarazi.
