Performance characteristics of external wall thermal insulation rock wool board

We all know that its main raw materials are solidified after being melted at high temperature. What are the specific performance characteristics? Let's find out together.

Rock wool board can be divided into fireproof rock wool board, waterproof rock wool board, aluminum foil rock wool board, high density rock wool board Cotton board, composite rock wool board, etc.

1. Thermal insulation performance: good thermal insulation performance is the basic characteristic of rock wool and slag wool products. The thermal conductivity of rock wool is usually 0.03-0.047W/(moK under normal temperature conditions (about 25°C). )between.

2. Combustion performance: The combustion performance of rock wool and slag wool products depends on the amount of flammable adhesives. Rock wool and slag wool are inorganic mineral fibers and are not combustible. In the process of processing into products, organic binders or additives are sometimes added, which will have certain effects on the combustion performance of the products. Impact.

3. Sound insulation performance: rock wool and slag wool products have excellent sound insulation and sound absorption performance, and the sound absorption machine Linyi color steel sandwich panel manufacturer reason is that this product has a porous structure. The structure of the sandwich panel manufacturer, when the sound wave passes through, friction occurs due to the action of the flow resistance, so that part of the sound energy is absorbed by the fiber, which hinders the transmission of the sound wave.

4. Fireproof: The raw material of the exterior wall rock wool board is natural volcanic rock, which is a non-combustible building material fireproof material.
