Is the thermal insulation of the steel structure house of the light steel villa good? -wellcamp light steel villa manufacturers

In recent years, the rise of simple life light steel structure villas in the construction industry is well known. Everyone knows that the light steel structure villa has a very good thermal insulation effect, but not everyone is familiar with which material to use to achieve the thermal insulation effect. In practice, extruded polystyrene is used. Simple life light steel structure villa adopts 180mm thick extruded board wall to achieve the effect of heat insulation. The thermal resistance of the wall is 4.24 K ㎡/W, and the thermal insulation performance index is equivalent to 10-11 times that of the brick-concrete wall. Since extruded polystyrene has a very good thermal insulation effect, how can he have such an effect? Below, I will give you a detailed introduction. The chemical name for extruded board is Styrofoam. Styrofoam is divided into expandable polystyrene and continuous extruded polystyrene. Compared with polystyrene board, polystyrene board is the third generation of rigid foam thermal insulation material. In terms of technical application, it solves the disadvantages of the very complex polystyrene board process technology, and has superior performance that cannot be replaced by polystyrene board. It is made of polystyrene resin and other additives through extrusion process with a continuous uniform surface layer and a closed-cell honeycomb structure. Those honeycomb-structured slabs have no voids at all. Insulation materials with closed cell structures can have different pressures (150-500 kPa) while having the same low thermal conductivity (only 0.028 W/m·g) and long-term excellent thermal insulation and compression performance indicators, the compression strength is 220-500 kPa. In addition to excellent thermal insulation properties, there are other performance properties. Next is a detailed introduction to the performance characteristics of the extruded board. The outstanding thermal insulation performance has the characteristics of high thermal resistance, low linearity and low expansion rate. Its structure has a closed cell rate of more than 99%, and it evolves into a vacuum layer to avoid airflow and heat dissipation, ensuring the durability and stability of the wall insulation performance. Compared with 80% closed cell ratio of foamed polyurethane, its main advantage is obvious. Practical experience has proved that the thermal insulation effect of 20mm thick polystyrene extruded insulation board is similar to that of 50mm thick expanded polystyrene and 120mm thick cement perlite, so this material is a very good choice for steel building insulation. . Outstanding super-strength bearing capacity Due to the special structure of XPS board, its compressive strength and impact resistance are high. According to different types and thicknesses of polystyrene, its compressive strength can reach more than 150 ~ 500 kpa, and can withstand the ground bearing capacity of various systems. Mainly used in geothermal engineering, highway, airport runway, square ground, large cold storage, interior decoration and wall insulation and other fields. High-quality hydrophobicity and moisture resistance and water absorption are crucial parameters for measuring thermal insulation materials. After the thermal insulation material absorbs water, the thermal insulation performance of the wall decreases. Under ultra-low temperature, the inhaled water is very easy to freeze, damage the structure of the insulation material, reduce the compressive strength of the board and the performance of the wall insulation. In view of the fact that the molecular formula of polystyrene itself does not absorb water, and the molecular formula of the plate is stable, there are no gaps, and the phenomenon of water leakage, penetration, frosting, and condensation of other materials has not been solved. Excellent stability and corrosion resistance In long-term use, extruded polystyrene board will not age, decompose or generate harmful substances. Its chemical properties are relatively stable and will not degrade due to water absorption and corrosion, which will reduce its performance. It can still maintain its excellent performance in high temperature natural environment. According to relevant data, even after 30 to 40 years of use, extruded polystyrene board can still maintain excellent performance, and it will not decompose or mold, and it will not volatilize toxic substances.
