ʻO Silicon Carbide Porous Foam Honeycomb Ceramic kānana
ʻO nā huahana kānana ceramic foam nā huahana ceramic me ka ʻano porous e like me ka foam i hana ʻia e kahi kaʻina hana kūikawā. Loaʻa iā lākou nā pōmaikaʻi he nui e like me nā waiwai kemika paʻa, ikaika kiʻekiʻe, kūpaʻa wela kiʻekiʻe, kūpaʻa haʻalulu maikaʻi, a me kahi ākea kikoʻī nui. Hoʻohana nui ʻia lākou. I ka metallurgy, ka hoʻolei ʻana, ka mālama ʻana i ke kaiapuni a me nā māla ʻē aʻe.
| Hoʻohālike | AIA AKU NEI | BHS-1 | BHS-2 |
| Mea lako | Alumina (Al2O3) | Kapili Silika (SiC) | Kapili Silika (SiC) |
| He kūpono no ke kānana ʻana i nā ʻano metala hoʻoheheʻe | Aluminum huila | ʻAi keleawe, hao hina hina | Hoolei hao |
| Mahana hana (℃) | 1200 | 1500 | 1550 |
| ʻAiʻi ʻAha (ppi) | 10～40 | 8~25 | 8~25 |
| ʻO ka kānana metala no ka nui ʻāpana (kg/cm2) | 1~1.5 | 3～5 | 3～5 |
| lākiō o ke kelepona hāmama（%） | 80～90 | 80～90 | 80～90 |
| Ka ikaika compressive ma ka lumi wela (MPa) | ≥0.8 | ≥1.0 | ≥1.2 |
| ʻAno nui (g/cm3) | 0.35～0.5 | 0.35～0.5 | 0.35～0.5 |
Nā hiʻohiʻona:
1. E ho'ēmi i ka helu hōʻole o nā castings a ho'ēmi i nā hemahema porosity
2, he hopena kānana koʻikoʻi
3. E hoʻomaikaʻi i ka hana mechanical o nā castings
4. E hoʻomaʻamaʻa i ka ʻōnaehana gating a hoʻomaikaʻi i ka wikiwiki o ka hoʻohana ʻana i ka template
5. Loaʻa ka nui o ke kahe metala, a paʻa ke kahe
6. ʻOi aku ka ikaika o ka hana ma ka wela kiʻekiʻe, ke kūpaʻa haʻalulu wela a me ke kūpaʻa ʻana o ke kahe metala
7. E ho'ēmi i ka manawa machining a me ka pōʻino mea hana
8. He kiʻekiʻe kiʻekiʻe ka nui o ka pono.
Noi:
1. E kau i loko o ke kīʻaha ninini a i ʻole ka lalo o ka sprue
2. Hoʻokomo ʻia ʻo ia ma luna o ka mea holo, i hiki ke hoʻopiha pono ʻia ka metala i hoʻoheheʻe ʻia, e pale aku i ka hopena pololei i ka kānana a i ʻole ke kau pololei ʻana i ka mea holo. ʻO ke kahe o ka metala hoʻoheheʻe wikiwiki a loaʻa iā ia kahi mana hoʻopiha maikaʻi.
3. Pono e hoʻoholo i ka nui o ka kānana e like me nā mea e like me ka hoʻohālike a me ka hoʻoheheʻe ʻana a me nā ʻano o ka kānana ponoʻī.
4. Pono e hoʻomaluʻia ke poʻo hoʻolei e like me ka hiki ke hoʻemi i ka hopena o ka metala i hoʻoheheʻeʻia ma ka kānana.
5. ʻAʻole pono e hoʻohana ʻia ka kānana ma luna o ka mahana
6. Hōʻalo i ka hoʻohana ʻana i nā kānana e hoʻokele i ka wikiwiki o ka hoʻolei ʻana
E koho i ka nui kānana a me ka nui mesh:
1. E noʻonoʻo i ka maʻemaʻe o ka metala i hoʻoheheʻe ʻia a me ka wela o ka ninini ʻana
2. E noʻonoʻo i ke poʻo hao ninini a helu i ka wahi mana kahe e hoʻokō i nā koi o ka manawa ninini
3. E ho'āʻo e hoʻohana i ka ʻōnaehana puka hāmama e pale i ka hoʻopaʻa ʻana o ka ea
4. E helu a koho i ka wahi kānana e like me ka hiki ke kānana a me ka ninini ʻana i nā koi manawa. ʻO ka hiki ke kānana ʻana o ka pepa silika carbide foam ceramic (Kg/cm2): Haʻahina hina: 4.0 Haʻa haʻahaʻa: 2.0 Alloy cast iron: 1.0-2.0
5. Hoʻohana ka hao hina maʻamau i ka 20ppi, hoʻohana ka hao ductile i ka 10ppi. Hiki ke koho ʻia ʻo 15 a i ʻole 25ppi, a pili ka koho mesh i nā kumu he nui i ka ninini maoli ʻana.
