ʻO ka hoʻolei ʻana he ʻano metala ʻenehana hana wela i haku ʻia e nā kānaka ma mua, nona ka mōʻaukala ma kahi o 6000 mau makahiki. ʻO ka hoʻolei ʻana he ʻano hana e hoʻoheheʻe ai i ka metala paʻa i loko o ka wai, ninini ʻia i loko o ke ʻano o ke ʻano kikoʻī, a laila paʻa. ʻO nā mea o ka pahu valve he one maka, pālolo, aniani wai, resin a me nā mea kōkua ʻē aʻe. I ke kenekulia 20, wikiwiki loa ka hoʻomohala ʻana o ka hoʻolei valve. ʻO kekahi o nā mea koʻikoʻi ka holomua o ka ʻenehana huahana valve, kahi e pono ai ka ʻoi aku ka maikaʻi o ka mīkini a me ke kino a me ka hana machining maikaʻi; ʻO ke kumu ʻē aʻe ʻo ka hoʻomohala ʻana o ka ʻoihana valve ponoʻī i hana i nā kūlana waiwai kūpono no ka ʻoihana foundry. ʻO ka ʻōlelo aʻe e pili ana i ke kaʻina hoʻolei valve a me ka hoʻohālikelike kumukūʻai.
ʻO ka hoʻoheheʻe ʻana i ka wax hoʻoheheʻe haʻahaʻa, ʻo ia ke kaʻina hana ʻana o ka silica sol, aʻo ka wax wela haʻahaʻa e hui pū ʻia me ke kaʻina hana o ka sodium silicate! ʻOi aku ka nui o ka emi ʻana o ka wax wela haʻahaʻa ma mua o ka wax wela haʻahaʻa no ka mea aia ka mahu wai i loko o ka paʻi wax wela haʻahaʻa. A hoʻohana mau ʻia ka wax wela haʻahaʻa me ka ʻenehana wai aniani shell! ʻOi aku ka nui o ka emi ʻana o ka wax wela haʻahaʻa ma mua o ka wax wela haʻahaʻa no ka mea aia ka mahu wai i loko o ka paʻi wax wela haʻahaʻa. He aha ka ʻokoʻa ma waena o ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa?
1. Hoʻohui ʻia ka wax wela kiʻekiʻe me ke kaʻina hana ʻana o ka pūpū silica sol, ʻoiai ʻo ka wax wela haʻahaʻa e hui pū ʻia me ke kaʻina hana ʻana o ka ʻili sodium silicate.
