The SPD water-based foamed polyurea sound insulation insulation board takes full water foam polyurea foam as the core. The system stability is enhanced through composite fiberglass mortar cloth, and is suitable for scenes such as rough houses and finely decorated floor heating. The usage method can be summarized into the following key steps: 1. Prepare the base layer before construction: ensure that the base layer is flat, dry, and free of cracks and depressions. If there are defects, it needs to be repaired and leveled in advance. Clean up dust, oil and other impurities on the surface of the base layer to ensure the bonding effect. Material inspection: Check whether the size and specifications of the insulation board meet the design requirements. The diagonal error should be less than 3mm and the allowable dimension deviation is ±2mm. Confirm that the auxiliary materials such as waterproof tape, vertical sound insulation sheet, wire mesh, etc. are of qualified quality and are not damaged. Environmental requirements: The construction ambient temperature should not be lower than 5℃ to ensure stable material performance. Avoid construction in severe weather such as rainy days and strong winds to prevent moisture from invading and affecting the bonding effect. 2. Positioning of the insulation board installation line: According to the design requirements, at the base layer

The advantages of J-type rock wool insulation and decorative integrated board are as follows: excellent thermal insulation performance, low thermal conductivity: As the core insulation material, rock wool has a thermal conductivity of only 0.018~0.024W/(m·K), which is about 1/2 of traditional EPS materials, which can effectively reduce heat transfer and reduce heating and cooling energy consumption. The energy-saving effect is significant: when meeting the same insulation requirements, the thickness of the building's outer enclosure structure can be reduced and the indoor use area can be increased. Home use can reduce the air conditioner electricity bill by 30% to 50%, saving an average of 900 to 1,500 yuan per year. Excellent fire resistance Class A fireproof material: Rock wool itself has extremely high fire resistance, fire resistance level reaches A1, high temperature resistance above 1200℃, no toxic gases are produced during combustion, it complies with the requirements of the new national fire protection regulations and can effectively prevent the spread of fire. Safety guarantee: Applicable to buildings with strict fire prevention requirements, such as high-rise residential buildings, commercial centers, etc., providing reliable protection for the safety of personnel and property.

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

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

Polyurethane hard bubble waterproof and insulation integrated board is a new type of building board that integrates waterproof, insulation, heat insulation, lightweight, durability and other functions. It is widely used in industrial factories, cold storage, civil buildings exterior walls, roofs and other scenarios.

The following is a detailed introduction to the advantages: 1. Excellent thermal insulation performance Low thermal conductivity The thermal conductivity of polyurethane hard foam is only 0.022-0.028 W/(m·K), far lower than traditional insulation materials (such as polystyrene board 0.038 W/(m·K), rock wool 0.035 W/(m·K)), which can effectively reduce heat transfer and reduce building energy consumption. Application scenario: It is suitable for buildings with severe cold areas or high energy-saving requirements, such as northern residential exterior wall insulation, cold storage enclosure structure, etc. Closed cell structure, moisture-proof and heat-insulated polyurethane hard bubbles have a closed cell rate of up to 95%, making it difficult to penetrate moisture, avoiding water absorption

Q-shaped rock wool insulation and decorative integrated board is a new building exterior wall material integrating thermal insulation, fire protection and decorative functions.

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.
