Second, adiabatic insulation properties Rock wool products have a small thermal conductivity, about 25 ° C under normal temperature conditions, thermal conductivity between 0.035 ~ 0.044W / (mk), light weight, non-toxic soft and easy to process. It is widely used in metallurgy and chemical construction.
Third, sound absorption performance:
Rockwool products have excellent sound insulation and sound absorbing properties. The sound absorbing mechanism is the porosity of the products, and the pores can penetrate each other and most of them are not sealed, thus forming a flow resistance. When the sound wave passes through this time, friction is generated due to the action of the flow resistance, and a part of the acoustic energy is changed into heat energy to be lost or absorbed by the fiber, which is widely used in auditoriums, shopping malls, theaters, subways, stations, airports, hotels, and high-end residences.
