● Kūleʻa wai

ʻAʻole loaʻa ʻo Rockwool i ka 2Cao a me SiO2, no laila ʻoi aku ka kiʻekiʻe o kāna mau mea kū'ē ma mua o ka hulu hipa mineral.Nui ka ʻokoʻa ma waena o ka hulu hipa pōhaku a me ka hulu hipa mineral no ka waiwai PH, ʻoi aku ka liʻiliʻi o ka hulu hipa pōhaku ma mua o 4, ʻoi aku ka paʻa o ka wai-kūpaʻa i ka mineral fiber;ʻOi aku ka nui o ka hulu hipa mineral ma mua o 5, a ʻoi aku paha ma mua o 6, ʻoi aku ka paʻa o kona kūpaʻa wai a ʻaʻole paʻa.Ma muli o kēia ʻokoʻa ma waena o lākou, ʻaʻole pono e hoʻohana ʻia ka hulu hipa mineral i nā kūlana pulu, ʻoi aku hoʻi i ka papahana insulation anuanu.Ma ka papahana insulation anu, ke kuhikuhi o ka wela kahe mai waho kahe i loko, a insulation 'enekinia kahe ka wela ma ka 'ē aʻe.Ma waho o ka makū e komo i loko o ke anuanu insulation mea i loko me ka wela emi, hau e condenses i loko o ka wai, ina e hoʻohana ana i ka mineral hulu hipa i keia kulana, ka pulupulu e lohi e luku hydration, hoemi i ke ola o ke anu insulation papa. aole loaa keia hemahema.No laila, no ke kūkulu ʻana i ka ʻōnaehana insulation hiki ke hoʻohana wale i ka hulu hipa pōhaku e like me ka mea hoʻokaʻawale.

● Kū'ē wela kiʻekiʻe

Ke piʻi ka mahana hana o ka hulu hipa mineral i 675 ℃, ma muli o kona hoʻololi kino ʻana, e liʻiliʻi ka liʻiliʻi a ʻoi aku ka nui o kona leo, ma hope o ka hoʻomaka ʻana o ka pulverization a me ka wāwahi.No laila, ʻaʻole pono e hoʻonui ʻia ka mahana hana o ka hulu hipa mineral ma mua o 675 ℃.No laila, ʻaʻole hiki ke hoʻohana ʻia ka hulu hipa mineral i nā hale a me nā hale.

ʻOiai ʻaʻole i loaʻa kēia pilikia i ka huluhulu pōhaku, hiki ke piʻi ka mahana hana i 800 ℃, ʻoiai ʻo ka mea nui CS-C2-AS-CAS2 eutectic point ʻo 1265 ℃, hiki ke piʻi i kona mahana palupalu i 900 ℃ -1000 ℃.

● Ke kū'ē i ka corrosion

ʻO ka hana nui o ka hoʻoheheʻe ʻana i ka umu ahi e hoʻoneʻe i ka hapa nui o ka sulfur e pale ai i ka wela i hana ʻia ma ke ʻano o ka fragile.E mau ana ka sulfur wehe i loko o ka umu e like me ka calcium sulfide (CaS).I ka hana ʻana i ka hulu hipa mineral, e lilo kēia ʻāpana o CaS i ka hulu hipa mineral, ʻo ia ka mea ma kahi o 5%.

ʻO ka hulu hipa pōhaku ka basalt a i ʻole ka diabase, koe wale nō ka liʻiliʻi o ka sulfur i lawe ʻia e ka coke i ka wā o ka hoʻoheheʻe ʻana, ʻaʻohe kumu o ka sulfur, no laila ʻaʻohe hopena ʻino i ka metala.
