Shijiazhuang extruded sheet is also called polystyrene resin, referred to as Xiuwu XPS. It is mainly used for thermal insulation. Because its thermal insulation coefficient is smaller than that of benzene board, it can use a smaller thickness than benzene board to achieve energy saving requirements when making exterior wall insulation materials. Shijiazhuang extruded sheet manufacturers come to share the differences between different quality extruded sheets .
The high-quality Shijiazhuang extruded board has a high bulk density, which makes the wall temperature very close to the indoor temperature, that is, while the indoor temperature rises and falls, the extruded board can maintain the indoor by adjusting the difference in heat absorption and heat release. The temperature is within a stable range. In the winter, it can block the indoor thermal energy from being transmitted outward and consume less; in the summer, it can block the outdoor heat from being transmitted inward, which is often referred to as warm and cool in summer.
The poor quality of Shijiazhuang extruded sheet has fallen behind in the choice of raw materials. Most cities use recycled plastic foam, such as lunch boxes, to process. Except for the large difference in bulk density, the compression resistance is also poor. After that, it is easy to cause deformation and cracking. Because this kind of extruded board contains a large amount of impurities, once a fire occurs, it will not only be unable to prevent fire, but also become a combustion accelerator, posing a huge threat to human life and safety.
The use in the insulation industry is relatively common, but we must pay attention to the correct method of use when using it, it is a common problem that the cavity of the extruded board appears in the construction, then how should we avoid this during the construction What about this situation? In the process of removing the scaffolding of the project, it is necessary to timely handle and repair the voids contained in the wall. It can be filled by using the same base material of the wall holes. Note that the cement mortar is used for smoothing during the process.
In the process, the board should be cut according to the basic size of the hole, and the edges should be polished to ensure that the hole can be tightly sealed and filled. During the construction of the project, it is necessary to wait for the inside of the hole to be filled with a special adhesive used after the cement mortar has solidified. It is necessary to pay attention to apply special adhesive and bottom polymer mortar along the four perimeters.
