Ka Nānā ʻana i ka Flame Retardant a me nā Manaʻo no nā Uhi Hoʻokaʻawale Pākahi

Hana ka mea kūʻai aku i nā mea hoʻokaʻawale pila, a hiki ke uhi ʻia ka ʻili o ka mea hoʻokaʻawale me kahi papa, ʻo ia hoʻi ka alumina (Al₂O₃) me kahi liʻiliʻi o ka mea hoʻopaʻa. Ke ʻimi nei lākou i nā mea pale lapalapa ʻē aʻe e pani i ka alumina, me nā koi penei:

• Ka pale ʻana i ka lapalapa maikaʻi ma 140°C(e laʻa, ka palaho ʻana e hoʻokuʻu i nā kinoea inert).
• Paʻa electrochemicala me ka launa pū ʻana me nā ʻāpana pila.

Nā mea pale lapalapa i ʻōlelo ʻia a me ka loiloi

1. Nā mea pale lapalapa synergistic Phosphorus-Nitrogen (e laʻa, Modified Ammonium Polyphosphate (APP) + Melamine)

ʻAno hana:

• Hoʻohui pū ke kumu waikawa (APP) a me ke kumu kinoea (melamine) e hoʻokuʻu i ka NH₃ a me ka N₂, e hoʻoheheʻe ana i ka oxygen a hana i kahi papa ʻala e ālai ai i nā lapalapa.
  Nā Pōmaikaʻi:
• Hiki i ka synergy phosphorus-nitrogen ke hoʻohaʻahaʻa i ka mahana decomposition (hiki ke hoʻololi ʻia i ~140°C ma o ka nano-sizing a i ʻole ka formulation).
• He kinoea inert ka N₂; pono e loiloi ʻia ka hopena o ka NH₃ ma ka electrolyte (LiPF₆).
  Nā Manaʻo:
• E hōʻoia i ke kūpaʻa o ka APP i loko o nā electrolytes (e pale i ka hydrolysis i loko o ka phosphoric acid a me NH₃). Hiki i ka uhi ʻana o ka silica ke hoʻomaikaʻi i ke kūpaʻa.
• Pono ka hoʻāʻo ʻana i ka hoʻohālikelike electrochemical (e laʻa, cyclic voltammetry).

2. Nā mea pale lapalapa i hoʻokumu ʻia i ka naikokene (e laʻa, nā ʻōnaehana hui Azo)

Moho:ʻO Azodicarbonamide (ADCA) me nā mea hoʻoulu (e laʻa, ZnO).
ʻAno hana:

• Hiki ke hoʻololi i ka mahana palaho i 140–150°C, e hoʻokuʻu ana i ka N₂ a me ka CO₂.
  Nā Pōmaikaʻi:
• He kinoea inert kūpono ʻo N₂, ʻaʻole ia he mea ʻino i nā pila.
  Nā Manaʻo:
• Nā huahana ʻaoʻao kaohi (e laʻa, CO, NH₃).
• Hiki i ka Microencapsulation ke hoʻoponopono pololei i ka mahana o ka decomposition.

3. Nā ʻōnaehana hana wela Carbonate/Acid (e laʻa, Microencapsulated NaHCO₃ + Waikawa Source)

ʻAno hana:

• Poha nā microcapsules ma 140°C, e hoʻoulu ana i kahi hopena ma waena o NaHCO₃ a me ka waikawa organik (e laʻa, ka waikawa citric) e hoʻokuʻu i ka CO₂.
  Nā Pōmaikaʻi:
• He inert a palekana ka CO₂; hiki ke hoʻokele ʻia ka mahana o ka hopena.
  Nā Manaʻo:
• Hiki i nā iona sodium ke hoʻopilikia i ka lawe ʻana o Li⁺; e noʻonoʻo i nā paʻakai lithium (e like me LiHCO₃) a i ʻole ke hoʻopaʻa ʻana iā Na⁺ i loko o ka uhi.
• E hoʻomaikaʻi i ka encapsulation no ke kūpaʻa o ka mahana o ka lumi.

Nā Koho Hiki ʻĒ Aʻe

• Nā ʻōnaehana Metal-Organic (MOFs):e laʻa, hoʻopau ʻo ZIF-8 i nā mahana kiʻekiʻe e hoʻokuʻu i ke kinoea; nānā no nā MOF me nā mahana hoʻopau like.
• Zirconium Phosphate (ZrP):Hoʻokumu i kahi papa pale i ka wā o ka decomposition thermal, akā pono paha e hoʻonui nui ʻia e hoʻohaʻahaʻa i ka mahana decomposition.

Nā Manaʻo Hoʻokolohua

1. Ka Nānā ʻana i ka Thermogravimetric (TGA):E hoʻoholo i ka mahana o ka palaho a me nā ʻano hoʻokuʻu kinoea.
2. Hoʻāʻo Electrochemical:E loiloi i ka hopena ma ka ionic conductivity, interfacial impedance, a me ka hana cycling.
3. Hoʻāʻo ʻana i ka pale ʻana i ke ahi:e laʻa, hoʻāʻo kuni kū pololei, ana ʻana o ka emi ʻana o ka wela (ma 140°C).

Hopena

ʻO kaka mea pale ahi synergistic phosphorus-nitrogen i hoʻololi ʻia (e laʻa, APP i uhi ʻia + melamine)ua ʻōlelo mua ʻia ma muli o kona pale ʻana i ke ahi kaulike a me ka mahana palaho hiki ke hoʻololi ʻia. Inā pono e pale ʻia ka NH₃,nā ʻōnaehana hui azoa i ʻolenā ʻōnaehana hoʻokuʻu CO₂ microencapsulatedhe mau koho ʻē aʻe kūpono. Manaʻo ʻia kahi hōʻoia hoʻokolohua pae ʻia e hōʻoia i ka paʻa electrochemical a me ka hiki ke hana.
