No ka hoʻomaopopo ʻana i ke ʻano helu helu o ka mānoanoa o ka refractory castable, he aha ka lua ea?
1. Aia ʻekolu ʻano pores:
1. Paʻa kekahi ʻaoʻao a kamaʻilio ʻia kekahi ʻaoʻao me waho, i kapa ʻia ʻo open pore.
2. Hoʻopili ʻia ka pore i pani ʻia i ka hāpana a ʻaʻole pili me ka honua o waho.
3. Ua kapaia na puka ma na puka.
ʻO ka nui o ka porosity, ʻo ia hoʻi ka porosity ʻoiaʻiʻo, e pili ana i ka pākēneka o ka nui o ka nui o nā pores i ka huina o ka hāpana;Ma keʻano laulā, ua hui pū ʻia ka puka puka me ka puka hāmama, a ʻoi aku ka liʻiliʻi o ka puka pani a paʻakikī ke ana pololei.No laila, hōʻike ʻia ka porosity e ka porosity hāmama, ʻo ia hoʻi, ka porosity ʻike.Hōʻike ka porosity i ka pākēneka o ka nui o ka nui o nā pores hāmama i ka hāpana i ka huina o ka hāpana.
ʻO ka mānoanoa nui e pili ana i ka lakio o ka leo castable o ka hāpana maloʻo i kona huina nui, ʻo ia hoʻi, ka ratio o ka leo castable o ke kino porous i kona huina nui, i hōʻike ʻia ma Kg/m3 a i ʻole g/cm3.ʻO ka porosity ʻike a me ka puʻupuʻu nui kekahi o nā kumu no ka mālama ʻana i ka nui o ka refractory castable i ke kūkulu ʻana.Hiki ke ana 'ia na papa kuhikuhi hana elua me ka laana hookahi.ʻO kēia ka nui o ka nui a me ka porosity o nā mea hoʻoheheʻe refractory maʻamau.
2. Eia ka mānoanoa nui a me ka porosity ʻikea o nā mea hoʻoheheʻe refractory maʻamau.

3. Ua hōʻike pōkole ʻia ka mānoanoa o ka castable sima haʻahaʻa ma lalo nei
Lawe ʻia ka sima alumina calcium haʻahaʻa ma ke ʻano he mea hoʻopaʻa, a ʻo nā mea hoʻoheheʻe me ka ʻiʻo CaO ma lalo o 2.5%, ua kapa ʻia ʻo ia ʻo nā kima haʻahaʻa.ʻOkoʻa i nā castables kahiko, ua hoʻomākaukau ʻia nā pahu sima haʻahaʻa ma ka hoʻololi ʻana i ka hapa nui a i ʻole nā mea āpau o ka alumina kiʻekiʻe me ka pauka superfine (ka nui o nā ʻāpana ma lalo o 10 microns) me ka hoʻopaʻa ʻana agglomeration me ka mea like a i ʻole ka like ʻana o ka mea nui, e hoʻonui ana i ka nui o ka nui. ka hāʻawi ʻana, ka pauka micro, ke ʻano ʻāpana a me nā mea ʻē aʻe, a me ka hoʻohui ʻana i kahi mea liʻiliʻi o ka dispersant (mea hoʻemi wai), ka nui o ka retarder a me nā mea hoʻohui ʻē aʻe.
He 2.26g/cm ³ ka mānoanoa o ka pālolo ha'aha'a ciment refractory castable.
Ka mānoanoa o kiʻekiʻe alumina haʻahaʻa sima refractory castable mea 2.3 ~ 2.6g/cm ³ e pili ana.
Corundum haʻahaʻa sima refractory castable me ka mānoanoa o 2.65~2.9g/cm ³ e pili ana.
