No laila, ʻo ke aniani wai no ka hoʻolei kālā ʻana he aniani wai sodium, ʻo ia hoʻi ʻo Na20·mSiO2, A transparent a translucent colloidal aqueous solution i hana ʻia ma hope o ka hydrolysis. ʻO nā mea kemika nui o ke aniani wai he silicon oxide a me ka sodium oxide. Eia kekahi, loaʻa iā ia kahi liʻiliʻi o nā haumia. ʻO ke aniani wai ʻaʻole ia he pūhui hoʻokahi, akā he hui pū ʻana o nā pūhui he nui.
Ma ke kaʻina hana hoʻolei kālā, ʻo ke aniani wai a me ka uhi ʻana i ka hana paʻa, ke kumu kūʻai haʻahaʻa, ka pōʻaiapuni hana pōkole a me ka noi kūpono. ʻO ke kaʻina hana hana wai aniani wai kūpono no ka hana ʻana i nā hoʻoheheʻe kālā e like me ke kila kalapona, ke kila haʻahaʻa haʻahaʻa, ka hao hao, ke keleawe a me nā alumini e pono ai ka maikaʻi o ka ʻili.
ʻO nā mīkini hoʻoheheʻe kila maʻamau maʻamau ekaʻina hoʻoheheʻe wax investmentme ke aniani wai (ka hoʻonā wai o ka sodium silicate) ma ke ʻano he mea hoʻopaʻa no ka hana ʻana i ka pūpū. ʻO ka maikaʻi o ka hana ʻana i ka pūpū e hoʻoikaika i ka pololei o nā hoʻoheheʻe hope loa a no laila he hana koʻikoʻi loa ia i ka wā o ka hoʻolei kālā. ʻO ka maikaʻi o ka pūpū e pili pono ana i kaʻeleʻele a me ka hoʻomanawanui ʻana o ka hoʻolei hope.
