He came he came he came with the Shijiazhuang extruded board

We probably don't hear much about Shijiazhuang extruded sheet in our daily life, but it is a good thing for us.

Shijiazhuang extruded sheet is used for a long time without aging, decomposition, and generation of harmful substances. Its chemical properties are stable, and it will not be degraded due to water absorption and corrosion, which will reduce its performance and maintain its performance under high temperature environments. Superior performance. According to the introduction of related materials, even if XPS extruded insulation board is used for 30 to 40 years, it can still maintain excellent performance without decomposition or mildew, and there is no volatilization of toxic substances.

The water absorption of Shijiazhuang extruded board is an important parameter for measuring insulation materials. The thermal insulation performance of the thermal insulation material decreases after it absorbs water. Under low temperature conditions, the absorbed water is likely to freeze, which damages the structure of the thermal insulation material, thereby reducing the compression and thermal insulation performance of the board. Because the molecular structure of polystyrene itself does not absorb water, the molecular structure of the plate is stable and there are no gaps, which solves the problems of water leakage, penetration, frosting, and condensation of other materials.

Shijiazhuang extruded sheet has the characteristics of high thermal resistance, low linearity, and low expansion ratio. Its structure has a closed cell ratio of more than 99%. It forms a vacuum layer to avoid air flow and heat dissipation, and ensures the durability and stability of its thermal insulation performance. The closed cell ratio of 80% of foamed polyurethane is self-evident. Practice has proved that the thermal insulation effect of 20mm thick XPS extruded insulation board is equivalent to 50mm thick expanded polystyrene and 120mm thick cement perlite. Therefore, this material is the current choice for building insulation.
