ʻO ka pāpaʻi graphite no ke kinikini electrolysis electrode

Ua hoʻomohala mākou i nā papa bipolar graphite maikaʻi loa e koi ana i ka hoʻohana ʻana i nā papa bipolar kiʻekiʻe me ka conductivity uila kiʻekiʻe a me ka ikaika mechanical maikaʻi. Hoʻomaʻemaʻeʻia e ke kiʻekiʻe-press forming, vacuum impregnation, a me ke kiʻekiʻe-mehana wela lapaʻau, ko mākou papa bipolar i nā hiʻohiʻona o ke kū'ē kū'ē, ka pale wela, ke kū'ē i ke kaomi, ke kū'ēʻana i ka corrosion, ke kū'ēʻana, ka aila-free self-lubrication, liʻiliʻi hoʻonui coefficient, a me ka hana hoʻopaʻa maikaʻi.

Hiki iā mākou ke mīkini i nā papa bipolar ma nā ʻaoʻao ʻelua me nā māla kahe, a i ʻole ka mīkini ʻaoʻao hoʻokahi a i ʻole e hāʻawi pū i nā pā palaka unmachined. Hiki ke hana ʻia nā papa graphite āpau e like me kāu hoʻolālā kikoʻī.

Nā palena ʻenehana

Nā pōmaikaʻi nui o kā mākou pā bipolar:

1. Ultra-kiʻekiʻe conductivity, kōkua pono hoʻololi ikehu
ʻO ka graphite maʻemaʻe kiʻekiʻe ≥99.9%, conductivity a hiki i 150 S / cm, e hōʻoiaʻiʻo ana i ka nalowale ʻole o ka lawe ʻana i kēia manawa.
ʻO ke kūpaʻa haʻahaʻa haʻahaʻa: Hoʻomaʻamaʻa ʻia ka ʻili ma ka pae nano, a ʻo ke kūpaʻa hoʻopili me ka papa diffusion gas he ≤10mΩ·cm², kahi e hoʻomaikaʻi ai i ka mana hoʻopuka o ka pahu wahie.

2. Paʻa ikaika loa i ka corrosion, hiki ke hoʻololi i nā kaiapuni paʻakikī
Paʻa kemika maikaʻi loa: Hiki iā ia ke kū i nā ʻakika ikaika (e like me ka waikawa phosphoric), nā alkali ikaika a me ka wela kiʻekiʻe a me nā wahi haʻahaʻa kiʻekiʻe, me ka ʻole o ka ua ion metala.
ʻenehana pale anti-oxidation (koho): Ua hoʻohui ʻia ka papa pale ʻo Silicon carbide (SiC) ma o ke kaʻina hana CVD, a hoʻonui ʻia ke ola ma mua o 3 mau manawa.

3. Hoʻolālā māmā, hoʻemi i ka ikehu ʻōnaehana
ʻOi aku ka māmā ma mua o 1.8 g/cm3: 20% ʻoi aku ka māmā ma mua o nā pā metala bipolar, kūpono no nā hiʻohiʻona paʻakikī e like me nā pahu wahie i kau ʻia i ke kaʻa.
Hoʻolālā lahilahi: Hiki ke hoʻopili ʻia ka mānoanoa i 0.8.0-2.0mm, e hoʻonui ana i ka nui o ka hoʻopaʻa ʻana a me ka hoʻomaikaʻi ʻana i ka ikehu.

4. Ke ola lōʻihi a me ka uku mālama haʻahaʻa
ʻO ka ikaika flexural ≥ 40 MPa: Ke kūʻē i ka hopena mechanical maikaʻi loa, e pale ana i ka haki ʻana.
Ke kū'ē'ē: Ka hana mau no 10,000 hola ma 80 ℃ a me 95% haʻahaʻa, hoʻohaʻahaʻa hana <5%.
