Rock wool Sandwich Panel Machine Roller with hydraulic 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.

Features
1. Light Self-weight-Installation is convenient and flexible without the large-size lifting devices so that the construction period is limited with the lower comprehensive costs.
2. Heavy Load-bearing Capacity:-It features high strength and high rigidness and is suitable either for the weight-bearing structure or for the protective structure.
3. Good Temp-keeping & Heat Insulation:-With hard polystyrene foams, average thermal conductivity 0.021w/m.k.
4. Fine fireproof-Test by national quality inspection center for fireproof building material, polystyrene sandwich panel index reach grade B2 and grade A of GB8624 respectively.
5. Flexible Application-As the continuous production line is controlled by the computer system, the length of the compound sheets will be decided and selected according to the designing requirement, transportation and installation conditions. It is possible to select the different thickness of the composite panels in accordance with the roof load-bearing and purlin distance.
