Matters needing attention in construction
For the thermal insulation and sound absorption layer after spraying, ventilation and drying environment should be provided. Usually, when the average temperature is 25 C and the relative humidity is less than 60%, the drying and curing time is 24-72 hours according to different thickness. After that, other processes such as decoration can be carried out.
PROTECTION OF SPRAYING PRODUCTS
Before spraying, hangers of various pipelines, air ducts and other equipment should be installed to avoid drilling and chipping on the base after spraying.
During the drying and solidification period, the finished product of spraying should be avoided from mechanical collision and rainwater erosion.
Local repairs should be made when the sprayed coating is damaged due to collision. For those parts which are often vulnerable to mechanical collision, glass fiber cloth or other protective materials can be coated to protect the surface of the fiber layer.
Keep the spraying area clean, avoid dust flying, and pollute the surface of finished product spraying coating.
During spraying construction, spraying operators should wear dust-proof masks and safety belts in accordance with the relevant provisions of the State Labor Protection Regulations.
Overview of Technology
With the implementation of energy saving and emission reduction as policy indicators, a large number of energy-saving and environmental protection materials came into being. Mineral fibre spraying with fire protection, heat preservation, sound absorption and noise reduction has become the representative of new energy-saving and environmental protection materials, and it stands out among many energy-saving and environmental protection construction schemes with its advantages of fast, convenient and advanced technology. "Mineral fibre spraying" technology has been applied in a large number of Engineering buildings.
Such as: Bird's Nest, National Stadium, Capital Airport New Terminal, Shanghai World Expo Enterprise Pavilion, Beijing-Shanghai High-speed Railway Shanghai Hongqiao Hub, Nanjing South Station Hub, etc. With the continuous development and improvement of this technology, the application field of mineral fiber spraying is expanding. It has been successfully applied in dozens of places such as underground garage, equipment room, exterior wall, transportation hub, stadium, art center, museum, workshop and so on.
