Nyocha na Ntụnye ọkụ maka mkpuchi nkewa batrị

Onye ahịa na-emepụta ihe nkesa batrị, na elu nkesa nwere ike kpuchie ya na oyi akwa, nke a na-ejikarị alumina (Al₂O₃) na obere ihe nkedo. Ha na-achọ ugbu a ọzọ retardants ire ọkụ iji dochie alumina, yana ihe ndị a chọrọ:

• Ọkụ na-adịgide adịgide dị mma na 140 Celsius(dịka ọmụmaatụ, ire ere iji hapụ gas inert).
• Nkwụsi ike nke electrochemicalyana ndakọrịta na akụrụngwa batrị.

Ndị na-egbochi ire ọkụ akwadoro na nyocha

1. Phosphorus-Nitrogen Synergistic Flame Retardants (dịka, Ammonium Polyphosphate (APP) + Melamine gbanwere)

Usoro:

• Acid isi iyi (APP) na gas isi iyi (melamine) na-emekọrịta ihe iji hapụ NH₃ na N₂, na-agbaze oxygen ma na-akpụ akwa cha cha iji gbochie ire ọkụ.
  Uru:
• Mmekọrịta phosphorus-nitrogen nwere ike wedata okpomọkụ nke ire ere (nwere ike ịgbanwe na ~140 Celsius site na nano-sizing ma ọ bụ nhazi).
• N₂ bụ gas inert; Mmetụta NH₃ na electrolyte (LiPF₆) chọrọ nyocha.
  Atụmatụ:
• Nyochaa nkwụsi ike APP na electrolytes (zere hydrolysis n'ime phosphoric acid na NH₃). Ihe mkpuchi silica nwere ike melite nkwụsi ike.
• Nnwale ndakọrịta elektrọnik (dịka ọmụmaatụ, voltammetry cyclic) chọrọ.

2. Nkwụghachi ọkụ dabere na Nitrogen (dịka, Sistemụ Ngwakọta Azo)

Nwa akwukwo:Azodicarbonamide (ADCA) nwere ndị na-arụ ọrụ (dịka, ZnO).
Usoro:

• Okpomọkụ ire ere na 140-150C, na-ahapụ N₂ na CO₂.
  Uru:
• N₂ bụ ezigbo gas inert, na-adịghị emerụ ahụ na batrị.
  Atụmatụ:
• Ngwa njikwa (dịka ọmụmaatụ, CO, NH₃).
• Microencapsulation nwere ike gbanwee okpomoku ire ere.

3. Carbonate/Acid Thermal Reaction Systems (dịka, Microencapsulated NaHCO₃ + Acid Source)

Usoro:

• Microcapsules gbawara na 140ºC, na-akpalite mmeghachi omume n'etiti NaHCO₃ na organic acid (dịka, citric acid) ịhapụ CO₂.
  Uru:
• CO₂ enweghị ike ma dị mma; okpomọkụ mmeghachi omume bụ ịchịkwa.
  Atụmatụ:
• ion sodium nwere ike igbochi njem Li⁺; tụlee nnu lithium (dịka ọmụmaatụ, LiHCO₃) ma ọ bụ immobilizing Na⁺ na mkpuchi.
• Kwalite ihe mkpuchi maka nkwụsi ike nke ụlọ-okpomọkụ.

Nhọrọ ndị ọzọ nwere ike ime

• Ọla-Organic Frameworks (MOF):dịka ọmụmaatụ, ZIF-8 na-emebi na okpomọkụ dị elu iji hapụ gas; ihuenyo maka MOF nwere okpomọkụ ire ere dakọtara.
• Zirconium phosphate (ZrP):Na-etolite akwa mgbochi n'elu ire ere ọkụ, mana ọ nwere ike ịchọ nano-sizing iji wedata okpomọkụ ire ere.

Nkwanye nnwale

1. Nyocha Thermogravimetric (TGA):Kpebie ọnọdụ ire ere na ihe ntọhapụ gas.
2. Nnwale Electrochemical:Nyochaa mmetụta na ionic conductivity, mgbochi ihu, na ịrụ ọrụ ịgba ígwè.
3. Nnwale ọgbaghara ire ọkụ:Dịka ọmụmaatụ, nnwale ọkụ kwụ ọtọ, nha nha nke thermal shrinkage (na 140°C).
