Tips for using carbon fiber felt mainly include the following aspects:
Surface treatment: Before using carbon fiber felt, the concrete surface needs to be treated. First, grind the concrete surface to remove the mortar and impurities on the surface, and then use a hair dryer to blow away the floating dust to ensure that the surface is clean and flat.
Adhesive preparation: When preparing the adhesive, the base glue main agent and the curing agent need to be mixed in a weight ratio of 3:1, and use an electric stirring machine to mix in the container for 2-3 minutes until the color is uniform. The preparation method of leveling glue and impregnation glue is the same.
Paste details: When pasting carbon fiber cloth, paste from the middle to both sides, so as to avoid the generation of bubbles and ensure smooth pasting. Use a degassing roller to roll the impregnation glue to penetrate the carbon fiber cloth. After the glue is dry, apply a layer of impregnation glue on the surface to protect the carbon fiber cloth.
Construction environment: Pay attention to the ambient temperature during construction, and try not to be lower than 5℃, otherwise it is necessary to take warming measures or use special matching resins for low temperature conditions.
