Grid cloth plays a very important structural role in the insulation system during construction, mainly to prevent the occurrence of cracks. The main reason is that grid cloth will not be easily injured when it is collided, unless it is a serious matter. However, grid cloth not only has impact resistance but is also easy to construct. Next, let's take a look at how to construct grid cloth to prevent the aging of the insulation layer!
Although the mesh cloth polyurethane rigid foam insulation layer itself has good anti-aging ability, it will also accelerate the aging of polyurethane foam materials in harsh environments such as long-term sudden cooling and heating. Therefore, improving the environment in which polyurethane rigid foam insulation materials are located, such as reducing ultraviolet radiation, minimizing water vapor and chemical erosion, maintaining moderate temperature and humidity, avoiding long-term rapid cooling and heating or prolonged exposure to cold and hot environments, slowing down their aging, and extending their service life, grid cloth is also very necessary for external wall insulation.
ZL rubber powder polystyrene particle insulation slurry contains a large amount of inorganic materials, and its aging performance is superior to that of polyurethane rigid foam organic materials. Using ZL adhesive powder polystyrene particle insulation slurry, a 1.5-2.0cm thick leveling treatment is applied on the surface of the polyurethane rigid foam insulation layer, which has the following protective and anti-aging effects on the polyurethane insulation layer: a. Through the 1.5-2.0cm thick adhesive powder polystyrene particle leveling layer, combined with the anti-aging properties of the crack resistant layer and mesh cloth decorative layer materials, it can effectively prevent UV damage to the insulation layer.
The grid cloth adhesive powder polystyrene particle leveling layer itself has a certain insulation effect, which can effectively alleviate the effect of cold and hot in winter and summer on the insulation layer, keep the insulation layer in a relatively constant temperature environment, and reduce the aging effect of cold and hot on the polyurethane insulation layer;
The high hydrophobicity and excellent breathability of the grid cloth adhesive powder polystyrene particle leveling layer can improve the humidity environment on the outer surface of the insulation layer, keeping it in a relatively stable state and reducing the impact of water vapor on the insulation layer.
Strengthening the insulation effect and reducing the thickness of the polyurethane insulation layer can save engineering costs and lower costs.
Compensate for the shortcomings of on-site spraying of polyurethane insulation materials in local areas such as windows, doorways, etc., and reduce the difficulty of construction.
The anti cracking technology route of flexible gradual release of stress layer by layer has been adopted, which can effectively prevent cracks in the protective surface layer and improve the stability and durability of the entire insulation system.
