ʻO Sand Ceramic no ka Mea Paipalapala 3D Binder Jet

ʻO ke one Ceramic no Binder Jet 3D Printer Kiʻi Hōʻike ʻia

ʻO ka wehewehe pōkole:

ʻO ke Sand Ceramic, i kapa ʻia hoʻi he ceramsite, cerabeads, ceramcast, he ʻano huaʻai spherical artificial maikaʻi i hana ʻia mai ka bauxite calcined. ʻO kāna mea nui he alumini oxide a me Silicon oxide. ʻOi aku ka maikaʻi o nā waiwai ma mua o ke one silica no ka loaʻa ʻana o ka hana ʻoi aku ka maikaʻi ma ka foundry. He kiʻekiʻe refractoriness, liʻiliʻi thermal expansion, ka huina angular maikaʻi, kahe maikaʻi maikaʻi loa, Kūʻē kiʻekiʻe i ka ʻaʻahu, ʻūhā a me ka haʻalulu wela, reclam kiʻekiʻeaʻoi aku ka maikaʻi o ke one ceramic sintered i kūpono loa i nā mea paʻi Binder jet 3D.
