Rock wool sandwich board is a good type of board, and the products produced and sold by the company have various advantages. Let’s take everyone together to learn more.
1. Excellent fire resistance performance: The raw materials, production process, and formula used in the rock wool sandwich panel make it have excellent fire resistance performance. Experiments have shown that it has a fire resistance of over 1000 ° C. The rock wool sandwich panel has been tested by an Italian testing agency and meets the fire protection requirements according to standards. The test results are as follows: 150mm thick rock wool sandwich panel RE130 80mm, thick rock wool sandwich panel REL60 100mm thick rock wool sandwich panel REL120.
2. Good insulation performance: The insulation performance is calculated based on the thermal conductivity of rock wool=0.043W/㎡ K and the thickness of the corresponding proportion of rock wool core material.
3. Significant sound absorption and insulation effect: Sound insulation: Rock wool sandwich panels have a good reduction effect on noise transmission, especially suitable for places with designated flights passing through. In addition, after the use of rock wool roof panels, rainwater and hail impact the roof steel plates of the building, causing indoor noise to be significantly reduced. Through testing, a density of 120kg/m was selected ³， The sandwich panel with rock wool as the core material can achieve a sound insulation effect of RW=29-30dB.
Sound absorption: Rock wool sandwich panels also have good attractive effects, which can absorb sound over a wide frequency range. The sound absorption performance of rock wool sandwich panels reaches DELTA LA=15.7dB (A). Changzhou Shunxiang Steel Structure Co., Ltd. has a variety of plates, purification plates, aluminum magnesium manganese plates, color steel tiles, etc. Welcome to call and purchase.
