ʻO ka maikaʻi o ka papa insulation rock wool e loaʻa i kēia mau ʻano:

ʻO ka mua, haʻahaʻa thermal conductivity.ʻO ka conductivity thermal kahi hōʻailona koʻikoʻi e ana i ka hana o nā mea hale prefabricated.He liʻiliʻi ka conductivity wela, a ʻo ka papa huluhulu pōhaku ʻonika me ka maikaʻi o ka hoʻokō wela wela ua kūpono ʻia ma o ka liʻiliʻi o ka hoʻoili waiwai.

ʻO ka lua, ka helu hoʻoheheʻe kani.Loaʻa iā ia ka hopena leo maikaʻi.ʻO ka papa huluhulu pōhaku insulation thermal e hilinaʻi nui ʻia i ka nui o kēlā me kēia ʻāpana.ʻOi aku ka nui o ka mānoanoa, ʻoi aku ka maikaʻi o ka lawe ʻana i ke kani.

ʻO ke kolu o ka helu ʻo ia ka haʻahaʻa o ka hygroscopicity.Ma hope o ka lawe ʻana i ka wai, e hoʻemi nui ʻia ka hopena mālama wela o ka mea mālama wela, no ka mea, ʻoi aku ka kiʻekiʻe o ka wai.No laila, makemake ʻia nā mea kūʻai aku e koho i ka papa hulu hipa pōhaku wai.

ʻO ka ʻakika coefficient kahi ana o ka lōʻihi kemika o ka hulu hipa pōhaku.ʻO ia ka ratio nui o ka huina o ka silica a me ka alumina i ka huina o ka calcium oxide a me ka magnesium oxide i loko o ka hui fiber.ʻO ke koena o ka acidity he helu helu nui e loiloi i ka maikaʻi o nā huahana hulu hipa pōhaku.He kiʻekiʻe ka ʻakika coefficient, maikaʻi ke kūpaʻa ʻana o ka wā a lōʻihi ke ola.I ka manawa like, he mea nui ka ʻakika e hoʻokaʻawale i waena o ka hulu hipa a me ka hulu hipa.Hoʻokumu ʻia ka mea maka o ka hulu hipa ma luna o ka slag a ʻoi aku ka liʻiliʻi o ka acidity coefficient ma mua o 1.5, a ʻo ka mea maka o ka hulu hipa pōhaku e pili ana i ka basalt, a ʻo ka coefficient acidity he ≥ 1.6.

ʻO ke kala o ka pulupulu pōhaku i hoʻolei ʻia e ka wela kiʻekiʻe he keʻokeʻo keʻokeʻo.He melemele-'ōmaʻomaʻo ke kala o ka hulu hipa pōhaku.Ma muli o ka hoʻohui ʻana o ka pulupulu pōhaku i kahi mea hoʻopili phenolic organik e hana ʻia i kekahi ʻano a me kekahi ikaika, kālua ʻia kēia ʻano mea hoʻopili ma 300-400 ° C a hoʻopili ʻia me ka hui kemika o ka hulu hipa pōhaku e hoʻololi i ke kala o ka hulu hipa pōhaku. pulupulu.
