The physical properties of rock wool boards can be seen from the following aspects, which are high temperature resistance, thermal conductivity, water absorption and other physical properties. What kind of relationship do these physical properties have with volume weight?
First, from the perspective of high temperature resistance, the relationship between the high temperature resistance of rock wool and volume weight can be summarized as the larger the volume weight, the smaller its volume weight loss under high temperature conditions. Taking rock wool with a volume weight of 50 kg as an example, when rock wool is in a high temperature environment of 800 degrees Celsius, its volume weight loss will be about 4.7%. While placing rock wool board with a volume weight of 100 kg in a high temperature environment of 800 degrees Celsius, the volume weight loss is about 4.2. It can be seen that the volume weight of rock wool still has a certain relationship with high temperature resistance.
And for thermal conductivity, it is directly proportional, that is, the larger the volume weight, the better its thermal conductivity, because it is like the wires common in our life, the larger the diameter, the greater the voltage it can carry. Therefore, the main physical properties of rock wool boards have their actual correlation.
The above data is for reference only, the specific basis needs actual testing, only theoretical basis.
