ʻO Foundry Ceramic Sand - ka hopena kūpono loa no kāu mau pono hana. ʻIke ʻia kēia huahana hou he ceramsite, cerabeads, a i ʻole ceramcast, a ua hana ʻia mai ka calcined bauxite e hāʻawi ana iā ia i kahi ʻano spherical grain maikaʻi loa. Me kona kiʻekiʻe o ka alumini oxide a me ka silicon oxide, ke kaena ʻo Ceramic Sand i nā waiwai ʻoi aku ka maikaʻi ma mua o ke one silica maʻamau.
Hāʻawi ʻo Ceramic Sand i nā pono he nui ma mua o ke one silica. ʻO ka mea mua, loaʻa iā ia kahi refractoriness kiʻekiʻe, e kūpono ana ia no ka hoʻohana ʻana i nā noi wela kiʻekiʻe. Loaʻa iā ia ka hoʻonui wela haʻahaʻa, e hōʻoiaʻiʻo ana i ka mālama ʻana i ke one a i ʻole ke ʻano kumu a me ka paʻa ʻana i ka wā wela loa.
Ma kahi o kona ikaika kupaianaha, hāʻawi ʻo Ceramic Sand i ka flowability maikaʻi loa - ʻo ia ka mea e hiki ke maʻalahi a hoʻoheheʻe ʻia i ka wā o ka hoʻolei ʻana. Eia kekahi, he kūpaʻa kiʻekiʻe ʻo Ceramic Sand i ka ʻaʻahu, ka ʻūhā, a me ka haʻalulu wela, e lilo ia i koho kūpono no nā ʻano hana hoʻoheheʻe āpau.
ʻO kekahi mea nui o ka hoʻohana ʻana i ka Foundry Ceramic Sand ʻo ia ka kiʻekiʻe o ka reclamation rate, ʻo ia ka mea hiki ke hoʻohana hou ʻia i ke kaʻina hoʻolei. ʻO kēia hoʻi, kōkua i ka hōʻemi ʻana i ka ʻōpala a hōʻemi i nā kumukūʻai.
ʻO ka holoʻokoʻa, ʻo Foundry Ceramic Sand he mea pono e loaʻa no kēlā me kēia foundry e ʻimi nei e hoʻomaikaʻi i kā lākou hana hoʻolei ʻana. Me kona mau waiwai maikaʻi a me kona ikaika kiʻekiʻe, hāʻawi ia i kahi pōmaikaʻi nui ma mua o ke one silica kuʻuna.
