ʻO Lonnmeter Group, kahi mea hana alakaʻi a me ka mea hoʻolako i nā mika density inline, ua hoʻolaʻa i nā makahiki he ʻumi i ka hāʻawi ʻana i nā ʻoihana loea no nā mea kūʻai aku ma ka honua holoʻokoʻa. Ua kōkua kēia mau hoʻonā i nā ʻoihana ʻoihana he nui, nā mea kanu mana, a me nā ʻoihana metallurgical e hōʻemi i nā kumukūʻai a hoʻomaikaʻi i ka pono.

ʻO ke kuleana koʻikoʻi o ka hui ʻana i ka Slurry

ʻO ka hana o ka hydrogen wahie cell MEAs hilinaʻi nui i ka uniformity a me ka paʻa o nā slurries catalyst. No ka la'ana, pono ka anode slurries i ka 15% Pt-C catalyst i hoolaha like 'ia i loko o ka solvent huikau o 40% wai deionized, 40% methanol, a me 5% ionomer solution; Ke koi aku nei nā slurries cathode i ka nui o ka catalyst (20%) a me ka binder (10%). ʻAʻole pili kēia lakio pololei i nā waiwai kino o ka slurry akā hoʻopili pololei i ka hoʻohele ʻana i nā wahi hana catalytic a me ka conductivity proton.

Hiki ke hoʻoulu ʻia ka catalyst agglomeration a i ʻole ka sedimentation ʻole ke kaohi pono ʻole, e hopena i ka mānoanoa like ʻole o ka catalyst i uhi ʻia a hiki i ka hana pākaukau holoʻokoʻa. No ka laʻana, hiki i ka mānoanoa kiʻekiʻe ke hōʻike i ka catalyst nui a i ʻole ka hoʻoheheʻe ʻana o ka solvent, e hoʻonui ana i ka slurry viscosity a me nā hemahema "ʻili ʻalani" a i ʻole "pinhole" i ka wā o ka uhi ʻana; ʻO ka haʻahaʻa haʻahaʻa paha e hōʻike ana i ka lawa ʻole o ka catalyst, ka hāʻawi ʻole ʻana i nā wahi pane kūpono a me ka hōʻemi ʻana i ka pono pākaukau.

ʻO nā palena o ka mana hoʻopaʻapaʻa slurry kuʻuna

ʻO ka hui ʻana o ka catalyst slurry maʻamau e hilinaʻi ʻia i ke kaupaona lima a me ka hoʻāʻo ʻana ma waho ma ka papa mua. He 15-30 mau minuke ka loaʻa ʻana o nā hopena hoʻāʻo mai ka laʻana, ʻo ia ka manawa i komo ai ka slurry i ke kaʻina hana aʻe, e alakaʻi ana i ka ʻōpala hana hou.

Paʻakikī nā hana lima no ka ʻike ʻana i ka hoʻohui ʻana o nā mea hoʻoheheʻe nanoscale catalyst. Eia kekahi, ʻo nā mea e like me ka hoʻololi ʻana o ka mahana a me ka evaporation solvent ke kumu o ka loli ʻana o ka dynamic density i nā slurries, ʻaʻole hiki i nā kaʻina hana kuʻuna ke uku i ka manawa maoli, e hoʻonui hou ana i nā pilikia instability maikaʻi.

Ke Kumu Hana a me nā Pono ʻenehana

No ka hoʻoponopono ʻana i kēia mau pilikia, ua hoʻomohala nā mea ʻenekini Lonnmeter i nā mika kiko laina e pili ana i ka manaʻo Coriolis force, e ana i ka pinepine o ka haʻalulu wai e loaʻa ai ka ʻikepili kiko manawa maoli me ka pololei a hiki i ±0.001 g/cm³. I loko o ka slurry hui ʻana o ka hydrogen fuel cell, hiki ke hoʻokomo ʻia kēia mau mea nānā pono kiʻekiʻe ma ka puka o ka hui ʻana i nā pahu a i ʻole nā ​​pipeline circulation e hōʻiliʻili mau i ka ʻikepili a me ka wela, me nā algorithms uku e hoʻopau i ka hopena o ka wela ma ka pā.

Ma waho aʻe o Coriolis density mika, ua hoʻomohala ʻo Lonnmeter i nā mika kikoʻī inline e like me ke kani ʻana i nā mika kikoʻī a me nā mika kani kani ultrasonic e hāʻawi i nā mea ʻike nānā ʻike naʻauao no nā kūlana hana like ʻole. I ka ʻike ʻana ua ʻoi aku ka nui o ka slurry cathode ma mua o ka waiwai i koho ʻia, e helu ʻokoʻa ka ʻōnaehana i ka deviation a hoʻohui i kahi nui kūpono o ka solvent ma o ka pauma ana; inā haʻahaʻa loa ka mānoanoa, hoʻohui ʻia ka waiʻona makuahine catalyst mua. ʻAʻole hoʻoponopono wale kēia mana loop dynamic i ka hoʻokaʻawale ʻana i ka formula akā wānana pū kekahi i nā pilikia ma o ka nānā ʻana i ka ʻikepili mōʻaukala. Ke ʻoi aku ka nui o ka nui o nā paepae, e hoʻāla ka ʻōnaehana i nā ʻōuli e hoʻolalelale like ʻole a i ʻole ka hoʻokaʻawale ʻana, e pale aku i nā pōʻino maikaʻi loa.
