STEINWOLLE.

摘要

The invention relates to stone wool formed from stone melt and consisting of 70 to 90 % by weight stone wool fibres having diameter of up to 5 mu m, 0 to 5 % by weight stone wool fibres having diameter above 5 mu m, and 10 to 25 % by weight shot having a diameter of at least 63 mu m, and in which the average diameter of the fibres is from 1 to 4 mu m, the ratio of average fibre length: average diameter is 1,000 to 3,000, the density is from 15 to 100 kg/m<3> and the thermal conductivity Lambda is from 30 to 40 mW/m DEG K at 10 DEG C.
