The method of using polyurethane spraying for thermal insulation includes the following steps: combining different thermal insulation materials to form a solution, and spraying a spray gun on the system that maintains the temperature of the polyurethane exterior wall to achieve the purpose of integrating water protection and thermal insulation. To a certain extent, reduce the thickness of polyurethane insulation materials. Because of this, the research on the development and application of the system for maintaining the temperature of the polyurethane exterior wall has and is of great significance.
The nature of rock wool board and the choice of rock wool board are the most important processing and production raw materials for natural ores such as basalt. Compared with other inorganic insulation materials, rock wool board has and has the following characteristics:
1. The basic feature of rock wool board is good thermal insulation performance. Among the inorganic thermal insulation materials, rock wool board has a low thermal conductivity, and it has and has application value in ultra-low energy consumption construction projects.
2. Rock wool board has and has excellent sound insulation and sound absorption performance, mainly due to the porous structure of rock wool products, which can effectively prevent the propagation of sound waves;
3. The rock wool quilt is applied to the exterior wall) external insulation, which can be in the form of a rock wool thermal insulation board (fibers parallel to the wall) of the entire wall, and it also has and has the function of external wall fire protection.
Polyurethane spraying construction for external wall insulation
The use of polyurethane spraying for heat preservation can also be used with other insulating materials, among which rock wool strips are used as a fireproof insulation layer (called a fireproof insulation layer, the fiber is perpendicular to the wall) 5, which is beneficial to improve the heat insulation effect of polyurethane rigid foam spraying. In the polyurethane exterior wall with low construction cost, simple operation and high energy consumption, the temperature-maintaining system in the polyurethane exterior wall has many characteristics such as low construction cost, simple operation and high energy consumption.
The insulation effect of the system that maintains the temperature outside the outer wall is better than that. The system that maintains the temperature outside the outer wall can improve the pressure resistance of the insulation material, and the insulation effect is better. application. Polyurethane heat preservation effect is better than that. Products that use polyurethane foaming machines widely have the advantages of heat preservation and insulation. They are currently called refrigerators.
The evaporation tube of the box body and the heat insulation of the box body are made of polyurethane foam material. Compared with asbestos, rigid polyurethane foam has and has many advantages. For example, regardless of the size and shape of the gap, foaming and filling can be filled and compacted, and the thermal conductivity is low, and the thermal insulation effect is good.
With the increasing awareness of environmental protection and occupational health, the research and manufacturing of polyurethane spraying for thermal insulation, the market share of the automotive and household appliances industry, especially the construction industry, has surpassed that of asbestos. The combination of black and white materials that are combined and reacted can form polymers with various physical properties.
According to the density and hardness of these polymers, various small and applied products can be produced. The application of polyurethane spraying for thermal insulation can be said to be quite extensive. For example, refrigerators, water heaters, etc., because of this, the quality level of construction technology and construction process is the key to control.
