ʻO Nickel foam kahi mea i hoʻohana ʻia e hana i nā electrodes pākaukau. ʻO ka mea maʻamau, ʻo ke ʻano hana o ka nickel foam material penei: mua conductive polyurethane sponge, a laila electrodeposition, a hope sintering.
Ma kēia kaʻina hana, hoʻohana maʻamau ka electroplating i ʻekolu mau ʻano: electroplating plating, electroplating conductive adhesive and vacuum plating; hiki i ka electrodeposition ke hoʻohana i ka sulfate a i ʻole sulfamate nickel plating; ʻO ke kumu o ke kaʻina hana sintering ʻo ia ka puhi ʻana i ka sponge polyurethane i ka lewa a hoʻemi i ka hydrogen. ʻElua mau ala no ka hoʻohaʻahaʻa sintering i ka lewa, kahi i puhi ʻia ai ka sponge polyurethane i ka lewa e ka oxidative decarburization treatment ma 300 ~ 700 °C; ʻO ka sintering a me ka ho'ēmiʻana e hanaʻia i loko o ka lewa hoʻohaʻahaʻa ma 800 ~ 1000 °C ma lalo o ka hydrogen ho'ēmi i ka lewa no 30 ~ 60 mau minuke,ʻO ka lewa hoʻohaʻahaʻa he kinoea amonia decomposition, aʻo ka hoʻohanaʻana i ke kinoea decomposition he 0.8 ~ 1.2 L / g (0.8). ~1.2 lita o ke kinoea decomposition ammonia i pau no ka gram nickel).
ʻO ke ala e pili ana i kahi ʻano hana no ka hoʻomākaukau ʻana i ka nickel foamed ma o ka hoʻokele ʻana, electrodeposition a me ka sintering o polyurethane sponge. ʻO ka mahana hoʻohaʻahaʻa ʻo 400 ~ 1000 ℃, ʻo ka manawa hoʻemi he 30 ~ 60 mau minuke, a ʻo ka hoʻohana ʻana o ke kinoea decomposition he 0.4 ~ 0.8 L / g. ʻO ke kinoea decomposition ammonia (0.4-0.8 liters o ke kinoea decomposition ammonia i pau i ka gram of nickel) he hui ia o ka nitrogen a me ka hydrogen, a ʻo kona lakio leo he 1:3.
ʻO ke ʻano o ka pane ʻana, aia i loko o ka lewa hoʻohaʻahaʻa hydrogen, ʻo ka nickel foam i loaʻa ka polyurethane sponge ua hoʻopili pololei ʻia a hoʻopaʻa ʻia e ka electrodeposition, a ʻo ke kalapona a me ka hydrogen e hoʻohua i nā hydrocarbons kinoea e like me CH4 a me C2H6. Hiki i kēia kaʻina hana gas ke hana i ka graphite i loko o ke kino porous. Hele mai ʻo C i ka mea hoʻomaʻemaʻe.
Pehea e mālama ʻia ai ka huʻa nickel?
1. E hoʻokumu i ka nickel foam e hōʻemi i ka hoʻohana ʻana i nā mea maka, me ka nui a me ke kaumaha māmā, e koi ana i ka pale ʻana i ke ahi, ka wai wai, ka ea a me nā koi ʻē aʻe; e hoʻokumu i kahi lumi mālama kemika: loaʻa iā ia nā hiʻohiʻona o nā ʻano like ʻole, hoʻohana ākea, nā ʻeke plastic moisture-proof, ventilation, etc.; hoʻokumu i ke keʻena mālama kemika , mea metala: ka hoʻomanaʻo nui o ka nickel metala
2. Hoʻonohonohoʻia ka helu o nā huahana o ka laina hana nickel foamed ma hope o kēlā me kēia wahi mālama. I mea e hoʻomaʻamaʻa ai i ka hana ʻana, mālama ʻia a me ka hoʻololi ʻana, ua hoʻonohonoho ʻia nā pahu hoʻopaʻa hana no nā huahana kūikawā.
3. Hoʻokumu ʻia nā huahana Nickel foam i ʻelua ʻāpana: ʻo ka hapa mua he huahana i hoʻopau ʻia me ka ʻoki ʻole ʻana, i mālama ʻia i kahi kaʻawale e pale ai i ka collision a me ka extrusion. Hoʻopili ʻia kēia mau ʻāpana ʻelua e like me ka makemake o ka mea hoʻohana i ka huahana, a ua hōʻailona maopopo ʻia ma ka pūʻolo. ʻO ka mālama ʻana, ka paʻi ʻana, ka moisture-proof a me ke kaomi ʻana i nā kūlana hōkele.
