ʻO ka nānā ʻana i ke ahi a me nā ʻōlelo manaʻo no nā uhi hoʻokaʻawale Batri

Hoʻopuka ka mea kūʻai i nā mea hoʻokaʻawale pākaukau, a hiki ke uhi ʻia ka ʻili o ka mea hoʻokaʻawale me kahi papa, maʻamau ka alumina (Al₂O₃) me kahi mea hoʻopili liʻiliʻi. I kēia manawa ke ʻimi nei lākou i nā mea pale ahi e pani ai i ka alumina, me nā koi penei:

• ʻO ka hoʻopaʻa ʻana i ke ahi ma 140 ° C(e laʻa, decomposing e hoʻokuʻu i nā kinoea inert).
• Paʻa electrochemicala me ka launa pū me nā ʻāpana pākahi.

Paipai ʻia ʻo Flame Retardants and Analysis

1. Phosphorus-Nitrogen Synergistic Flame Retardants (e laʻa, Modified Ammonium Polyphosphate (APP) + Melamine)

Mechanism:

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

2. ʻO nā mea hoʻopaʻa ahi ma muli o ka Nitrogen (e laʻa, nā Pūnaehana Hoʻohui Azo)

moho:ʻO Azodicarbonamide (ADCA) me nā mea hoʻoulu (e laʻa, ZnO).
Mechanism:

• Hiki ke hoʻololi i ka mahana decomposition i 140-150 ° C, e hoʻokuʻu ana i ka N₂ a me CO₂.
  Pono:
• ʻO N₂ kahi kinoea inert maikaʻi loa, ʻaʻohe pōʻino i nā pila.
  Nā manaʻo:
• E hoʻomalu i nā huahana (e laʻa, CO, NH₃).
• Hiki i ka Microencapsulation ke hoʻoponopono pololei i ka mahana decomposition.

3. Nā Pūnaehana Ho'ōla wela Kaona/Akika (e laʻa, Microencapsulated NaHCO₃ + Acid Source)

Mechanism:

• Nahā nā microcapsules ma 140°C, e hoʻoulu ai i ka hopena ma waena o NaHCO₃ a me ka waika organik (e laʻa, ka waikawa citric) e hoʻokuʻu i ka CO₂.
  Pono:
• ʻO ka CO₂ he mea ʻole a palekana; Hiki ke hoʻomaluʻia ka mahana hopena.
  Nā manaʻo:
• Hiki ke hoʻopilikia i nā iona sodium i ka lawe ʻana i ka Li⁺; e noʻonoʻo i nā paʻakai lithium (e laʻa, LiHCO₃) a i ʻole immobilizing Na⁺ i loko o ka uhi.
• E hoʻonui i ka encapsulation no ka paʻa ʻana o ka lumi.

Nā Koho Hiki ʻē aʻe

• Nā Papahana Metala-Organic (MOF):laʻa, hoʻoheheʻe ʻia ʻo ZIF-8 i nā wela kiʻekiʻe e hoʻokuʻu i ke kinoea; pale no nā MOF me nā mahana decomposition kūlike.
• Zirconium Phosphate (ZrP):Hoʻokumu i kahi papa pale ma luna o ka hoʻoheheʻe wela, akā makemake paha i ka nano-sizing e hoʻohaʻahaʻa i ka mahana decomposition.

Manaʻo hoʻokolohua

1. ʻIkepili Thermogravimetric (TGA):E hoʻoholo i ka wela decomposition a me nā waiwai hoʻokuʻu kinoea.
2. Electrochemical ho'āʻo:E loiloi i ka hopena i ka conductivity ionic, impedance interfacial, a me ka hana paikikala.
3. ʻO ka hoʻāʻo ʻana i ka hoʻopaʻa ahi:laʻa, ka hoʻāʻo ʻana i ke ahi kū pololei, ke ana ʻana o ka wela (ma 140°C).

Ka hopena

ʻO kahoʻololi ʻia ka phosphorus-nitrogen synergistic flame retardant (e laʻa, uhi ʻia APP + melamine)ʻōlelo mua ʻia ma muli o kona pale ʻana i ka lapalapa ahi a me ka mahana decomposition tunable. Inā pono e pale ʻia ka NH₃,ʻōnaehana hui azoa i ʻoleʻōnaehana hoʻokuʻu CO₂ microencapsulatedhe mau koho koho. Manaʻo ʻia kahi hōʻoia hoʻokolohua hoʻokolohua e hōʻoia i ka paʻa electrochemical a me ka hiki ke hana.
