1. Heʻokoʻa nā mea maka i hoʻohanaʻia i ka hana hana.Hoʻopau ʻia ka huluhulu Slag e like me ka hulu hipa mineral, a ʻo kāna mau mea maka nui he slag metallurgical a me nā koena ʻōpala ʻoihana a me ka coke.ʻO nā mea waiwai nui o ka hulu pōhaku pōhaku maoli e like me ka basalt a me ka diabase.

2. He okoa na ano kino.Ma muli o ka ʻokoʻa o nā mea maka, ʻokoʻa nō hoʻi ko lākou ʻano kino.Ma keʻano laulā, he 1.1-1.4 ka nui o ka acidity o ka hulu hipa, aʻo ka acidity coefficient o ka hulu hipa ma kahi o 1.4-2.0.Ma muli o ka haʻahaʻa haʻahaʻa haʻahaʻa o ka hulu hipa slag, loaʻa pū kekahi i nā ʻokikene alkaline.Aia kekahi hana hydraulic i loko o ka hulu hipa mineral, he ʻokoʻa loa ia mai ka hulu hipa pōhaku.No laila, ʻaʻole hiki ke hoʻohana ʻia ka hulu hipa maʻamau no ka insulation thermal o ke kūkulu ʻana i nā paia o waho.

3. He okoa ka hopena.ʻAʻole i loko o ka hulu hipa pōhaku ka sulfur manuahi, ʻoi aku ka haʻahaʻa o ka ʻike o ka pōleʻa slag ma mua o ka hulu hipa mineral, a ʻo nā huahana hulu hipa pōhaku e hoʻohana nui ana i ka resin hydrophobic ma ke ʻano he mea hoʻopaʻa.He kiʻekiʻe ke kiʻekiʻe o ka resin, no laila ua haʻahaʻa ka nui o ka hoʻoheheʻe ʻana o ka wai, a ʻoi aku ka kiʻekiʻe o ka wai ma mua o ka hulu hipa mineral.ʻO ka mahana hana kiʻekiʻe loa o ka hulu hipa mineral he 600-650 degere Celsius.ʻO ka maʻamau, ʻoi aku ka pōkole a me ka mānoanoa o ka fiber o ka huahana.Hiki ke piʻi ka mahana hana kiʻekiʻe o ka hulu hipa pōhaku i 900-1000 degere Celsius, lōʻihi ka fiber, a ʻoi aku ka lōʻihi o ke kemika ma mua o ka hulu hipa mineral, akā ʻoi aku ka kiʻekiʻe o ke kumu kūʻai o ka hulu hipa pōhaku ma mua o ka hulu hipa mineral.

4. Heʻokoʻa ka hana hana.ʻO ke kaʻina hana o nā huahana huluhulu pōhaku e hoʻomaʻamaʻa pololei i ka basalt a i ʻole ka diabase a me kahi liʻiliʻi o dolomite, limestone a fluorite a me nā mea hoʻohui ʻē aʻe i loko o kahi moku i hoʻoheheʻe ʻia ma kahi kiʻekiʻe o 1400-1500 degere Celsius i loko o kahi kīʻaha, a laila hana i nā fibers ma o he eha-roll centrifuge.I ka manawa like, ua hoʻoheheʻe ʻia ka resin wai a i ʻole ka silika organik a me nā mea hoʻopaʻa ʻē aʻe ma ka ʻili o ka fiber, a laila hana ʻia e ka sedimentation a me ke kaomi.ʻO ka hulu hipa mineral ka mea nui mai ka hoʻoheheʻe ʻia ʻana o ka hao, me ka nui o ka limestone a i ʻole dolomite a me nā pōhaku lepo.Hoʻoheheʻe ʻia ia i loko o kahi kīʻaha a i ʻole ka cellar ma kahi haʻahaʻa haʻahaʻa haʻahaʻa ma mua o ka wela hoʻoheheʻe ʻana o ka hulu hipa pōhaku, me ka hoʻohana ʻana i ke ʻano o ka injection a centrifugal.No ka hana ʻana i ka fiberized, koho ʻia nā pōpō slag a me nā haumia i loko o ka fiber ma ka winnowing a i ʻole ka wai.
