3.ʻO ka pahu huluhulu pōhaku kahi ʻano mea hoʻoheheʻe hulu hipa pōhaku i hoʻohana nui ʻia i nā paipu.Hana ʻia ia me ka basalt maoli a i ʻole ka hulu hipa mineral e like me ka mea nui.

4.Ma hope o ka hoʻoheheʻe ʻana i ka wela kiʻekiʻe, hana ʻia ia i loko o ka fiber inorganic artificial e nā lako centrifugal kiʻekiʻe.I ka manawa like, hoʻohui ʻia ka mea hoʻopili kūikawā a me ka ʻaila lepo lepo, a laila hoʻomehana ʻia a hoʻopaʻa ʻia i nā kikoʻī like ʻole o ka paipu hoʻoheheʻe pōhaku huluhulu.

5.Hana ʻia ka pūpū huluhulu pōhaku i ka diabase i koho ʻia a me ka basalt slag ma ke ʻano he kumu kumu nui, hoʻoheheʻe ʻia i ka wela kiʻekiʻe a hoʻoheheʻe ʻia me ka mea hoʻopili kūikawā a me ka wai wai i ka wā o ka centrifugation kiʻekiʻe, a hana ʻia me ka resin rock wool insulation tube shell a me ka wai pōhaku hulu hipa Insulation pūpū.

1.ʻO kahuluhulu pōhakuHana ʻia ka ʻōnaehana paipu i ka basalt ma ke ʻano he kumu nui a hoʻoheheʻe ʻia i loko o ka fiber inorganic artificial i ka wela kiʻekiʻe.Loaʻa iā ia nā pōmaikaʻi o ke kaumaha māmā, haʻahaʻa haʻahaʻa thermal conductivity, maikaʻi ke kani absorption, non-combustibility, a me ka paʻa kemika maikaʻi.
2.He ʻano hou ia o ka mālama ʻana i ka wela, ka hoʻokaʻawale ʻana i ka wela a me nā mea kani.
3.Loaʻa i ka paipu hulu hipa pōhaku nā waiwai o ka wai ʻole, mālama i ka wela, ka hoʻohaʻahaʻa ʻana i ka wela a me ka pale anu.Loaʻa iā ia ke kūpaʻa kemika a ʻaʻole ia e deliquesce inā hoʻohana ʻia no ka manawa lōʻihi ma lalo o nā kūlana haʻahaʻa.
4.No ka mea ʻaʻole i loko o kāna mau huahana ka fluorine (F-) a me ka chlorine (CL), ʻaʻohe hopena koʻikoʻi o ka hulu hipa pōhaku i nā mea hana a he mea hiki ʻole ke puhi.
