Talk about some factors that affect the insulation material
Today to introduce how to distinguish between exterior wall thermal insulation material of some quality problems, let the dongguan extruded board, and dongguan dongguan XPS extruded board, heat preservation and heat insulation board manufacturer to explain it for you, and now some of the insulation board has very good heat preservation performance, but because there are some insulation board the quality of the jagged, how to learn to distinguish the quality of the insulation board is very important.
The first thing to understand is that the specific heat capacity of an adiabatic material is calculated for an adiabatic structure that can be cooled, at room temperature, by no more than five percent of the mass of the adiabatic material.
Generally speaking, the coefficient of thermal conductivity and the direction of heat flow are generally the same, in different materials, for the heat transfer and some properties of the fiber arrangement is to be divided into two, so in different forms, the coefficient of thermal conductivity of the insulation material is much smaller.
This is because the coefficient of linear expansion of the adiabatic material will decrease as the temperature decreases.
