Hydraulic Operation Rock wool Sandwich Panel Machine Roller Double
Belt Machine
Rockwool color steel sandwich panels give full play to the unique
properties of rock wool core materials and significantly affect
fire, heat insulation, sound absorption and sound insulation.
(1) Good fireproof performance: The rock wool sandwich panel of raw
materials, production process and formula has good fireproof
performance.
(2) Good thermal insulation: The thermal insulation performance of
rock wool sandwich panels is based on the thermal conductivity of
rock wool = 0.043 w / m2K, and the corresponding thickness ratio of
rock wool core material is calculated.
(3) The sound absorption and heat insulation effect is remarkable:
Sound insulation: Asbestos sandwich panels have a significant
reduction in noise transmission and are especially suitable for
designated flights. In addition, after the use of rock wool roofing
panels, rainwater and hail caused roofing steel panels that
affected the building, causing the sound to be greatly weakened in
the room.
Sound Absorption: Rockwool sandwich panels also have a good suction
effect that absorbs sound over a wide frequency range.
