Steel structure FP expansion type Fire retardant coating Several times of construction
Steel structure FP expansion fire protection coating Generally, the coating shall be applied for 3-5 times, and the construction shall be carried out according to the fireproof performance requirements of steel structures and the performance inspection report of fire retardant coating products. The steel structure FP intumescent fire retardant coating is a product produced according to the GB14907-2018 specification. The product is Waterborne paint , add clean water during construction diluent Yes, no need to add other Auxiliary materials, After being exposed to fire, it can rapidly expand and thicken to form a dense and uniform fire and heat insulation carbonized protective layer, which can generate decomposition heat absorption reaction, prevent heat transfer, delay the temperature rise of the steel structure, thus greatly extending the fire resistance time of the steel structure.
instructions:
1. The following treatment construction shall be carried out after the acceptance of steel structure.
2. The surface of steel structural members shall be derusted and treated for rust prevention and corrosion prevention.
3. Before construction, the dust, grease, moisture, etc. on the surface of steel structure components shall be cleaned up. It is strictly prohibited to paint on wet surfaces.
4. Before use, the product must be fully mixed evenly. It can be diluted by adding appropriate amount of water according to the construction conditions. Excessive amount will affect its performance.
5. During construction, the thickness of one coat is about 0.5-1mm. The next coat shall be applied after the coat is dry. The thickness of each coat is about 1-2mm, and there shall be no missed coating. The interval between each coat is 8-24 hours. The thickness of the coat meets the design requirements.
6. The construction environment temperature should be between 5~35 ℃, the relative humidity should not be more than 80%, and the air should be well ventilated. When the wind speed is greater than 5m/s, rainy days or component surface is dewed, construction is not suitable.
