As temperatures gradually drop, polyurethane spray machine construction has entered its peak season. Although the construction process is not overly complex, it is crucial for Beijing's polyurethane high-pressure mixing spray construction personnel to master the correct procedures to ensure construction quality. The application of new building materials in insulation and energy-saving is particularly prominent, especially in the northern regions where higher requirements for insulation performance are placed. Therefore, the use of new materials can significantly enhance insulation properties and save heating resources.

The roof waterproofing layer is exposed to natural elements, intense sunlight, strong winds, rain and snow erosion, extreme temperature fluctuations, and the expansion and contraction caused by day and night temperature differences. Without good material performance and proper protection management, it is challenging to achieve the lifespan required by the enterprise. Therefore, it is essential to choose high-tensile strength, high-elongation waterproofing materials. The varying climatic conditions and environmental changes in humidity and temperature also present different requirements for waterproofing materials. Students should select waterproof building materials with distinct Chinese cultural characteristics based on local conditions, such as the southern regions with abundant rainfall, northern regions requiring waterproofing, and cold climates, especially in snowy areas where materials with low-temperature frost expansion and contraction resistance should be chosen.

Currently, the application of wood-insulating polyurethane spray machine technology in construction engineering has garnered sufficient attention and has been explored in various aspects in practice. To enhance the application value of various green building technologies in construction engineering, it is necessary to diversify the types of green building technology applications, ensuring that the application of green building technologies is more suitable and more widespread.

Spraying rigid polyurethane foam using a polyurethane spray machine involves quickly mixing two materials and then directly applying them to the surface of an object for foaming and shaping. Spraying is an important application method for polyurethane rigid foam plastics, used for insulating layers in cold storage, grain silos, residential buildings, factory roofs, walls, and storage tanks, and has been gradually推广 applied. The advantage of using a polyurethane spray machine for building insulation is that it does not require molds, allowing for the spraying of a rigid polyurethane foam insulating layer on both horizontal and vertical surfaces, simple or complex.
