Ubwino wa board wool insulation board uyenera kukhala ndi izi:

Choyamba, otsika matenthedwe madutsidwe.The matenthedwe madutsidwe chizindikiro chofunika kuyeza ntchito za prefabricated nyumba zakuthupi.Thermal conductivity ndi yaying'ono, ndipo bolodi lotenthetsera la rock wool lomwe lili ndi ntchito yabwino yotchinjiriza mafuta limatha kutengera mphamvu zochepa.

Chachiwiri, phokoso mayamwidwe coefficient.Imakhala ndi mayamwidwe abwino amawu.Thermal insulation rock wool board makamaka zimatengera kachulukidwe pagawo lililonse.Kachulukidwe kake, m'pamenenso mayamwidwe ake amamveka bwino.

Mfundo yachitatu ndi yakuti iyenera kukhala ndi hygroscopicity yochepa.Pambuyo poyamwa madzi, mphamvu yotetezera kutentha kwa zinthu zotetezera kutentha idzachepetsedwa kwambiri, chifukwa madzi ali ndi matenthedwe apamwamba kwambiri.Choncho, tikulimbikitsidwa kuti makasitomala asankhe bolodi lopanda madzi la rock wool.

The acidity coefficient ndi muyeso wa kukhazikika kwa mankhwala a ubweya wa miyala.Ndi kuchuluka kwa kuchuluka kwa silika ndi aluminiyamu ku kuchuluka kwa calcium oxide ndi magnesium oxide mu fiber.The acidity coefficient ndi index yofunikira yowunikira mtundu wa zinthu zopangidwa ndi ubweya wa miyala.Kuchuluka kwa acidity ndikokwera, kukana kwanyengo ndikwabwino komanso moyo wautali.Pa nthawi yomweyi, coefficient ya acidity ndi njira yofunikira yosiyanitsa ubweya wa miyala ndi ubweya wa slag.Zopangira za ubweya wa slag zimachokera ku slag ndipo coefficient ya acidity ndi yochepera 1.5, ndipo zopangira za ubweya wa miyala zimachokera ku basalt, ndipo coefficient ya acidity ndi ≥ 1.6.

Mtundu wa ulusi wa ubweya wa miyala wotayidwa ndi kutentha kwambiri nthawi zambiri umakhala woyera.Mtundu wa zinthu zopangidwa ndi ubweya wa rock nthawi zambiri umakhala wobiriwira wachikasu.Ndi chifukwa chakuti ulusi wa ubweya wa miyala umawonjezera zomatira za phenolic kuti zipangidwe mu mawonekedwe ena ndi mphamvu zina, zomatira zamtundu uwu zimaphikidwa pa 300-400 ° C ndipo zimakhudzidwa ndi mankhwala a ubweya wa miyala kuti asinthe mtundu wa ubweya wa mwala. fiber.
