  • How long is the service life of polyurethane hard foam insulation composite board
    How long is the service life of polyurethane hard foam insulation composite board
    2025-09-05
    Under normal use and maintenance conditions, the average lifespan of polyurethane hard foam insulation composite panels can reach more than 30 years, and some high-quality products can even reach 50 years. This conclusion is based on the following key factors: 1. Material characteristics and durability closed-cell structure: The porosity structure of polyurethane hard bubbles is stable, basically a closed-cell structure. This structure not only has excellent thermal insulation performance, but also has good freeze-thaw resistance and sound absorption. High closed cell rate can prevent air from flowing between the cells, reduce convection heat transfer, thereby improving thermal insulation performance and extending the service life of the material. Strong resistance to deformation: Polyurethane hard bubbles are not easy to crack, the finish is stable and safe, and can adapt to normal deformation of building structures without cracks, hollowing and other phenomena. Weather resistance and chemical stability: Polyurethane hard bubbles can be used for a long time in an environment of -50℃ to 150℃, and the short-term use temperature can even reach 250℃ without any damage. Its physical and chemical properties are very stable and insoluble in most solvents

  • Precautions for the use of polyurethane hard bubble insulation decorative integrated board
    Precautions for the use of polyurethane hard bubble insulation decorative integrated board
    2025-09-03
    Polyurethane hard bubble insulation and decorative integrated board (referred to as 'polyurethane integrated board') is a new building material integrating thermal insulation, decoration, waterproofing and other functions, and is widely used in building exterior wall insulation and decoration projects. The following matters should be paid attention to during use to ensure construction quality and long-term performance: 1. Prepare environmental conditions before construction. Temperature requirements: The construction environment temperature should be between 5℃ and 35℃. Heating measures should be taken at low temperatures (<5℃). At high temperatures (>35℃), direct sunlight should be avoided to cause the adhesive to cure too quickly. Humidity control: The relative humidity should be ≤80%. Construction is prohibited in rainy, foggy or strong windy weather (wind speed > level 5) to prevent moisture from affecting the bonding strength. Base layer treatment: The base layer wall needs to be flat, dry, oil-filled, and floating ash, and the flatness deviation is ≤4mm/2m (check with a 2-meter ruler). The concrete base layer needs to be maintained for more than 28 days, and the masonry walls need to be plastered and leveled and dried (including

    Precautions for the use of polyurethane hard foam insulation composite board
    2025-08-22
    Polyurethane hard bubble insulation composite board (PU hard bubble composite board) is a highly efficient and energy-saving building insulation material. It is composed of polyurethane hard bubble core material and metal or non-metal panels. It has the advantages of low thermal conductivity, strong wind pressure, and adjustable fire resistance. However, its use must strictly follow the specifications, otherwise it may cause insulation failure, safety hazards or shorten service life. The following are the key precautions and detailed descriptions: 1. Precautions for design stage fire protection performance matching standards: Select the fire protection level according to the 'Fire Protection Code for Building Design' (GB50016). For residential buildings with a building height of >54m or public buildings with a building height of >50m, the exterior wall insulation material must be Class A (not burnable). Other buildings can adopt B1 (flammable retardant) or B2 (flammable), but fireproof isolation belts are required. Non-standard scenarios: If the project requirements are higher than the national standards (such as data centers, chemical plants), PU hard foam core materials with flame retardant added (oxygen index ≥28%
