ʻO Sand Foundry Ceramic

ʻO ka wehewehe pōkole:

ʻO ke one hoʻokumu ʻia ʻo Al2O3 he one synthetic me ka refractoriness ʻoi aku o 1800 °C. Hoʻohana nui ʻia ke one hoʻoheheʻe ceramic ma ka ʻoihana foundry e like me ka hoʻoheheʻe ʻana a me ke one kumu ma muli o kona ʻano spherical kokoke loa, e hāʻawi ana i nā waiwai kahe maikaʻi a me ka permeation kinoea. Me ka kaumaha ʻole i ka ikaika koʻikoʻi, hiki ke mālama i ka 50% ma ka mea hoʻopili i ka hana kumu ke hoʻohālikelike ʻia me nā one ʻē aʻe. I ka manawa like, ʻoi aku ka maikaʻi o nā hoʻolei ʻana me ke one Ceramic no nā foundries.

E hoʻouna i ka leka uila iā mākou

Nā hiʻohiʻona

• Hoʻohui like ʻole
• Paʻa ka nui o ka palaoa a me ka ea permeability
• ʻO ka refractoriness kiʻekiʻe (1825°C)
• Kū'ē kiʻekiʻe i kaʻaʻahu, kaʻeha a me ka haʻalulu wela
• Hoʻonui wela liʻiliʻi
• ʻOi aku ka maikaʻi o ka wai a me ka hoʻopiha piha ʻana ma muli o ka spherical
• Kiekie loa o ka ho'iho'i hou 'ana i loko o ke one

Hoʻohana ʻia i nā kaʻina hana hoʻokumu ʻana i ke one

Kaʻina hana one i uhi ʻia i ka resin
ʻO ka pahu anu a me ke kaʻina hana one pahu mahana
Kaʻina paʻi one 3D
ʻO ke kaʻina one resin no-bake (E hoʻokomo i ka resin Furan a me ka resin Alkali phenolic)
Kaʻina hana hoʻopukapuka/ Kaʻina hana wax nalo/ Ka hoʻolei pololei ʻana
Kaʻina paona nalowale
Kaʻina aniani wai
