Te Tātaritanga Ārai Mura me ngā Taunakitanga mō ngā Paninga Wehewehe Pūhiko

Ka hangaia e te kiritaki ngā wehewehe pākahiko, ā, ka taea te pani i te mata wehewehe ki tētahi paparanga, ko te tikanga he alumina (Al₂O₃) me te iti o te mea here. Kei te rapu rātou i ētahi atu mea ārai mura hei whakakapi i te alumina, me ngā whakaritenga e whai ake nei:

• Te ātete mura whai hua i te 140°C(hei tauira, te pirau hei tuku i ngā hau kore mahi).
• Te pumau hikohikome te hototahi ki ngā wāhanga pākahiko.

Ngā Ārai Mura me te Tātaritanga e Manakohia ana

1. Ngā Ārai Ahi Whakakotahi Phosphorus-Hauota (hei tauira, Modified Ammonium Polyphosphate (APP) + Melamine)

Tikanga:

• Ka mahi tahi te pūtake waikawa (APP) me te pūtake hau (melamine) ki te tuku i te NH₃ me te N₂, ka whakawaiwai i te hāora, ka hanga he paparanga waro hei aukati i ngā mura.
  Ngā Painga:
• Ka taea e te mahi tahi o te whākawa-hauota te whakaiti i te pāmahana pirau (ka taea te whakarerekē ki te ~140°C mā te whakarahi-nano, mā te whakatakotoranga rānei).
• He hau kore mahi te N₂; me arotake te pānga o te NH₃ ki te electrolyte (LiPF₆).
  Ngā Whakaaroaro:
• Manatokohia te pumau o te APP i roto i ngā electrolytes (kaua e huri hei waikawa phosphoric me te NH₃). Mā te paninga silica ka pai ake te pumau.
• Me whai whakamātautau hototahi hikohiko (hei tauira, te cyclic voltammetry).

2. Ngā Ārai Mura e Hangai ana ki te Hauota (hei tauira, Ngā Pūnaha Matū Azo)

Kaitono:Azodicarbonamide (ADCA) me ngā kaiwhakaoho (hei tauira, ZnO).
Tikanga:

• Ka taea te whakarerekē i te pāmahana pirau ki te 140–150°C, ka tukuna te N₂ me te CO₂.
  Ngā Painga:
• He hau koretake te N₂, kāore e pā kino ki ngā pākahiko.
  Ngā Whakaaroaro:
• Ngā hua taha whakahaere (hei tauira, CO, NH₃).
• Ka taea e te microencapsulation te whakarite tika i te pāmahana pirau.

3. Ngā Pūnaha Tauhohenga Wera o te Kāponāte/Waikawa (hei tauira, NaHCO₃ + Pūtake Waikawa i roto i te Kapia Moroiti)

Tikanga:

• Ka pakaru ngā moroiti-kāpūkara i te 140°C, ka puta he tauhohenga i waenga i te NaHCO₃ me te waikawa waro (hei tauira, te waikawa citric) hei tuku i te CO₂.
  Ngā Painga:
• He koretake, he haumaru hoki te CO₂; ka taea te whakahaere i te pāmahana tauhohenga.
  Ngā Whakaaroaro:
• Tērā pea ka whakararuraru ngā katote konutai i te kawe i te Li⁺; whakaarohia ngā tote konutai (hei tauira, LiHCO₃) te aukati rānei i te Na⁺ i roto i te paninga.
• Whakapaipai i te whakakī kia pumau ai te pāmahana rūma.

Ētahi atu Kōwhiringa Pea

• Ngā Anga Whakarewa-Waiora (MOF):Hei tauira, ka pirau a ZIF-8 i ngā pāmahana teitei hei tuku i te hau; tirotirohia mō ngā MOF me ngā pāmahana pirau e ōrite ana.
• Te Hākawa Zirconium (ZrP):Ka hanga he paparanga ārai i te wā e pirau ana i te wera, engari me whakarahi ake pea i te rahi nano hei whakaiti i te pāmahana pirau.

Ngā Taunakitanga Whakamātautau

1. Tātaritanga Werohanga-ā-papa (TGA):Whakatauhia te pāmahana pirau me ngā āhuatanga tukunga hau.
2. Whakamātautau Hikohiko:Aromatawai i te pānga ki te kawe hiko ioniki, te aukati atanga, me te mahi huringa.
3. Whakamātautau Ārai Mura:hei tauira, whakamātautau mura poutū, ine whakahekenga wera (i te 140°C).

Whakamutunga

Tehe ārai mura whakakotahitanga o te phosphorus-hauota kua whakarerekētia (hei tauira, he APP kua pania + melamine)e taunakitia ana i te tuatahi nā te mea he taurite te ātete ki te mura me te pāmahana pirau ka taea te whakarerekē. Mena me karohia te NH₃,ngā pūnaha matū azorāneingā pūnaha tukunga CO₂ kua whakakīia ki roto i te capsules itihe huarahi kē atu e taea ai. E taunakihia ana kia whai mana whakamātautau ā-wāhanga hei whakarite i te pumau hikohiko me te whaihua o te tukanga.
