Ka Whakahou Anō te Hangarau Kukū Hurihuri-Wāhanga-Toru i ngā Paerewa Maimoatanga NMP – Ka Whakarewahia e Pengjin te Pūnaha Pourewa-Teitei o te Reanga Panuku

Ngā Mamae o te Ahumahi e Ārahi ana i te Whanaketanga Hangarau

I roto i ngā ahumahi hanga pākahiko lithium me ngā ahumahi haurua-ira, he uaua te rongoā i te hau N-methylpyrrolidone (NMP) hei hau putanga. He uaua ki ngā pourewa tuku iho te rerekētanga o te kukū, te iti o te pai o te tākai, me ngā utu whakahaere teitei. Ka tukuna e te 'pūnaha pourewa porowhita-toru-wāhanga hou' a Pengjin Technology ngā putanga rua o te pai me te pumau mā te hangarau auaha.

Hangarau Matua: Mekameka Tukanga Kukū Whakarōpūtia  

Katinga pūnaha：Wai parakore → mimiti → wāhanga kukū

1. Paparanga Wai Parakore (0-3% te kukū)

• Ka mau tonu te kukū o te hauhautanga o runga i te 3-6ppm (neke atu i te paerewa 10ppm a Haina).
• Ka whakahohehia e ngā pūoko atamai ngā takirere hau mō te waipuke aunoa, ka whakakorea te mana ā-ringa.

2. Paparanga Ngongo (kukū 3-30%)

• Mā te tohatoha tākai paparua me ngā paipa kawe ā-papa ka nui ake te horahanga hau me te pai o te mimiti.
• Ka taurite aunoa te taumata o te taupoki aukume i te whakawhiti wai i waenga i ngā paparanga.

3. Paparanga Kukū (kukū 30-80%)

• Mā te hoahoa rokiroki kua whakarōpūtia me ngā rōpū takirere hau ka taea te kukū i ia taahiraa.
• Ka whakaratohia e ngā kaukau pereti poka te tohatoha ōrite me te whakaiti i te whakapaunga pūngao.

Te Peke Mahi

Painga Whakataetae: Te Hiranga Hangarau o te Mekameka Katoa

Ka whakauruhia e ngā mōkihi tukanga ā-pūrere a Pengjin ngā mana whakahaere atamai me ngā auahatanga taputapu:

• Whakapai ake i ngā Rauemi: Kowiri tira 304L, ātete ki te waikura NMP mō te roa o te ora.
• Ngā otinga ritenga: Hoahoa tauine (30,000-50,000 m³/h).
