Hoʻohana ʻia ka lehu iwi mai ka iwi bipi maʻemaʻe i ka keramika a me ka metallurgy
Hoʻohana nui ʻia ia i ka hana ʻana i ka porcelain iwi kiʻekiʻe i ka ʻoihana seramika, a hiki ke hoʻohana ʻia i ke aniani opal, pigment stabilizer, polishing agent, syrup clarifier, etc.
ʻO ka lehu iwi papa A he lanahu iwi i hana ʻia a hiki i ka 120 mesh, hoʻohana ʻia i ka ʻoihana ceramic a me ka metallurgical demould a me ka hoʻomaʻemaʻe wai.
Lehu iwiloaʻa mai nā iwi holoholona ma hope o ka calcination ma ke kiʻekiʻe wela.Hoʻokomo ʻia ka iwi maka i loko o kahi pahu paʻa kiʻekiʻe a hoʻohui ʻia me ka nui o ka wai.Hoʻomohu ʻia ka iwi ma 150 ℃ no 2 mau hola, no laila e hoʻoheheʻe ʻia ka iwi i loko o nā poloka iwi me ka ʻole o ka protein, a laila maloʻo.
Hoʻokomo ʻia ka poloka iwi maloʻo deprotein i loko o kahi kiln wela kiʻekiʻe me ke kinoea maoli e like me ka wahie a puhi ʻia ma kahi wela kiʻekiʻe o 1250 ℃ no 1 hola a i ʻole ma kahi wela kiʻekiʻe o 1300 ℃ no 45 mau minuke.I loko o kēia manawa, ua pau ka 'N' i ka calcined a pau loa nā bacteria i ke ahi.
Hoʻopiʻi ʻia nā poloka kalapona iwi puhi ʻia a nānā ʻia i nā kikoʻī like ʻole e ka pale vibrating, ʻo ia ka mea maʻamau: 60-100 mesh, 0-3mm, 2-8mm, etc.
