①Before surface treatment and pasting of carbon fiber sheet, the line should be positioned according to the reinforced design position.
② Cut the carbon fiber sheet according to the size required by the design. The width of the cut fabric should not be less than 150mm and not less than 100mm.
③Wipe the surface of the carbon fiber sheet clean to no dust. When two layers need to be pasted, both sides of the bottom carbon fiber sheet should be wiped clean.
④The cleaned carbon fiber sheet should be coated with bonding resin immediately, and the glue layer should be convex, with an average thickness of not less than 2mm.
⑤Apply the carbon fiber sheet coated with bonding resin to the position to be pasted by hand. Use a rubber roller to evenly and steadily compact the fiber sheet to make the resin overflow from both sides to ensure compactness and no voids. When the carbon fiber is pasted in parallel, the void between the two sheets should not be less than 5mm.
⑥ When two layers of carbon fiber sheets need to be pasted, they can be pasted continuously. If it cannot be pasted continuously, clean the bottom carbon fiber sheet before starting again.
⑦The construction should be carried out at an ambient temperature of 5℃ or higher, and should comply with the construction temperature of the supporting resin. When the ambient temperature is lower than 5°C, a supporting resin suitable for low temperature should be used or heating treatment measures should be adopted.
⑧ The adverse effect of environmental humidity on resin curing should be considered during construction, and the moisture content of the concrete at the sticking position should not be greater than 4%.
⑨When preparing the resin, it should be weighed and placed in a container according to the proportion specified in the product instructions, and mixed with a stirrer until the color is uniform. There must be no oil and impurities in the mixing container. It is advisable to determine the mixing amount of the resin each time according to the actual temperature on site, and strictly control the use time.
⑩In order to ensure the quality of the paste, different types of paste resins should be used under different seasons and different temperature conditions, so as to effectively control the operating time and curing time of the resin construction.
