Ke one keramika i uhi ʻia i ka resina
wehewehe
Hoʻohana ʻia ke one keramika i loko o ke one hoʻoheheʻe a me ke one kumu e hana ai i ka mold shell a me ka shell core i nā waiwai o ke kūpaʻa wela kiʻekiʻe, haʻahaʻa haʻahaʻa, hāʻule maʻalahi, a me ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, hiki ke pale maikaʻi i nā hemahema hoʻonui i nā castings.No nā cores me nā hiʻohiʻona paʻakikī, hiki ke hoʻoponopono i ka pilikia ʻaʻole maʻalahi ka pana ʻana i ke one.ʻO ia ke one ceramic applicate i ka hana RCS.
Hoʻohana ʻia ke one ceramic piha e hana i ke one i uhi ʻia, a hoʻohana hou ʻia ma hope o ka hoʻihoʻi ʻana, hiki ke hoʻomaikaʻi maikaʻi i ka maikaʻi a me ka hana ʻana o nā castings, e hoʻemi i ka helu scrape castings a me ke kumukūʻai hana o nā ʻoihana, ʻoi aku ka haʻahaʻa o ka hoʻohana lōʻihi ma mua o kēlā. o ke one silika.No laila, i kēia mau makahiki i hala iho nei, ua hoʻohana ʻia nā mea kanu one i uhi ʻia i ka nui i ke one kalima ma ke ʻano he one maka e hana ai i ke one i uhi ʻia.
Nā hiʻohiʻona
• ʻOi aku ka refractoriness kiʻekiʻe—-e hoʻolei i nā metala me ke kiʻekiʻe o ka ninini ʻana i ka wela (ke kila hoʻolei ʻia, ke kila hoʻoheheʻe ʻia, ke kila kila, etc.)
• Ka ikaika kiʻekiʻe a me ka ʻoʻoleʻa—–e hana i nā cores paʻakikī me nā ʻāpana lahilahi.
• Hoʻonui ka wela haʻahaʻa—–e pale i nā hemahema hoʻonui.
• ʻOi aku ka nui o ka hoʻoulu hou ʻana—-e hōʻemi i ka hoʻolei ʻana i ke one ʻōpala, e hōʻemi i nā kumukūʻai.
• Hiki maikaʻi ke kahe —–e hana i nā cores paʻakikī.
• Hoʻemi haʻahaʻa i ka hoʻohana ʻana i ka binder—–e hoʻohaʻahaʻa i ke kinoea evolution, haʻahaʻa i nā kumukūʻai hana.
• Hiki ke hoʻohana ʻia i loko o nā mea hoʻoheheʻe kaulana, me ke kila Manganese.
• ʻOi aku ka lōʻihi o ka mālama ʻana.
