The carbon fiber surface treatment before percolation cloth

The carbon fiber surface treatment before percolation cloth 1 will be reinforcing concrete surface treatment of concrete road surface of the paint layer and loose parts thoroughly removed after the ground; If has reinforced the leakage, should be reinforced for derusting processing, and then use leveling repair glue, surface bulge with cutting machine or a grinder to make it. The corner convex Angle R more than 20 mm, or concave Angle to fill; If by reinforcing the concrete cracks, should be filled with structural glue perfusion after reinforcement. Ask concrete surface clean, dry, no oil. If there is water seepage by reinforcing part, should do first hydrophobic, water and dry processing, will be reinforcing the concrete surface with acetone or alcohol is wiped clean. 2 bottom glue construction when the temperature is below 5 ℃, the heavy rain days or when the relative humidity is more than 95%, not for construction. Of the construction of glue A and B in accordance with the provisions of two component with glue proportional weighing, pour into A clean container and stir evenly, with brush or roller brush evenly in the concrete surface, plastic table after dry, or multiple besmear brushs according to specific situation, but the thickness of the coating is less than 0. 4 mm and not leak brush or have flowed, bubble, after waiting for glue curing ( Depending on the field temperature, curing time with finger touch dry advisable, generally not less than 2 hours, then the next working procedure. Each preparation of adhesive solution should be applicable period of the glue once finished. 3 leveling construction when concrete surface concave part, will match good leveling glue to repair the bridge using embedded scraper scrape, template joint leveling height difference of part applications such as glue to fill, to minimize the difference. Corner, the processing of applying leveling glue to repair it for smooth arc, radius of not less than 20 mm. Leveling must cure ( Depending on the field temperature, curing time with finger touch dry advisable, generally not less than 2 hours) May be the next working procedure.
