What are the benefits of using a polyurethane spray machine for coating? In winter, effective insulation becomes a major concern in our daily lives. No matter how warm we dress, wind still seems to blow around us, indicating that our indoor insulation is far from ideal. To prevent that chilly “wind” sensation, exterior walls can also be treated with polyurethane spray insulation. Practice has shown this method to be highly effective, as evidenced by the following points.

　　In winter, effective thermal insulation becomes a major concern in our surroundings. No matter how warm it is, there’s always wind blowing around us, which indicates that our indoor insulation is still far from ideal. To avoid that “windy” sensation, the exterior walls can also be constructed using… Polyurethane spray machine . As it turns out, this approach works quite well too. This can be illustrated by the following points.

　　1. Polyurethane spray‑on insulation delivers excellent thermal performance; rigid polyurethane is an outstanding insulating material with a thermal conductivity of 0.024 W/(m·K). When applied using a sprayer, it forms a continuous insulation layer, ensuring the integrity of the insulation system and the wall assembly and effectively eliminating thermal bridges.

　　2. With a non‑cavity structure, it exhibits strong wind resistance; the polyurethane spray‑applied insulation layer is firmly bonded to the base wall, thereby reducing damage to the external thermal insulation system of high-rise buildings caused by wind pressure, particularly negative wind pressure.

　　3. Excellent resistance to damp heat and superior waterproofing: Rigid polyurethane foam boasts outstanding thermal insulation and unique impermeability, enabling it to replace conventional waterproofing and insulation layers and be widely used for thermal insulation of roofs and walls.

　　4. It exhibits excellent workability; rigid polyurethane coatings are applied using mechanized equipment, resulting in fast construction and high efficiency. To ensure the flatness of corner lines at internal and external angles and other edge details, it is advisable to install prefabricated polyurethane components, which helps minimize material waste and facilitates the fabrication of straight internal and external corners and edge profiles in subsequent processes, thereby enhancing overall construction quality and efficiency.

　　5. Excellent environmental protection; the insulation material itself exhibits high chemical stability and is formulated without chlorofluorocarbons (CFCs).

　　One of the key aspects of maintaining a polyurethane spray machine is cleaning. There are many important considerations during the cleaning process; employing proper and appropriate cleaning methods helps ensure that the machine’s performance remains increasingly stable across all parameters. So, what specific points must be carefully observed?

　　1. For the heating piping of the polyurethane spray equipment, after injection is complete, press the pressure‑release button to relieve the pressure and check whether the proportional piston rod has retracted into the cylinder. Once it has descended, stop releasing the pressure. Because there is some pressure inside the pipe, air and moisture are unlikely to enter the piping.

　　2. After use, be sure to thoroughly clean the surface of the extraction pump and store it in a maintenance sleeve containing a dedicated cleaning agent to prevent reactions between different components and atmospheric moisture, which can lead to reduced flow rates and issues such as decreased extraction efficiency and malfunctions of proportional valves. When performing a full‑system cleaning of the polyurethane spray equipment, schedule this thorough cleaning and sealing every month.
