Characteristics of mechanical slab of bridge opening

1. Good thermal insulation performance: the 40MM thick Shore rand board is equivalent to the thermal insulation effect of 300MM brick wall, and the moisture retention performance conforms to the second level (RAL RG426 standard).
2. Good sound insulation effect: the sound insulation effect of 40 mm thick Shore rand board can reach 28 dB. Comply with (DIN 4109 standard) efficient sound insulation.
3. Good impact resistance: Shore rand plate can evenly disperse the external force without causing any deformation (20 kg/cm2) when subjected to strong destructive impact.
4. Good flame-retardant performance: it can withstand flame for 15 minutes when doing experiments, which is the best performance of the board. (DIN 4102 standard) over 30min, low combustion rate;
5. Good stability: ensure the accurate thickness tolerance of core material is 0.1MM.
6. Environmental protection: the release of free formaldehyde reaches the E1 environmental protection standard.
