Xuangong carbon fiber cloth made of Japanese imports of Dongli carbon fiber quality (PAN based PAN based) raw materials, product performance in full compliance with national standards (GB50367-2006 "reinforced concrete structure design specification", GB/T  21490-2008 "structure reinforcement and repair with carbon fiber sheet").   specializing in carbon fiber strengthening building materials production, sales, and has the qualification of special professional engineering reinforcement! To purchase our reinforcement material, our company to provide technical advice, to provide on-site technical guidance, to provide free reinforcement special professional engineering qualifications! Specification for concrete structures strengthened with carbon fiber sheet   technology;
A: pasting carbon fiber sheet reinforced by hot repairing concrete structure noted the construction technology for professional application of finish, well should be strengthening and repairing scheme and construction technical measures. 1, the construction must follow the following process; (1) the construction preparation (2) concrete surface treatment; (3) preparation and brushed with the resin of the substrate: (4) preparation of leveling material and uneven repair: (5) preparation and brushing the impregnating resin or paste resin; (6) pasting carbon fiber sheet: (7) surface protection. 2, the construction should be in the 5 degrees above ambient temperature conditions, and shall comply with the construction of supporting resin using temperature ambient temperature below 5 C, should be supporting resin suitable for low temperature environment or by heating treatment measures. 3, construction should take into account the adverse effect of environmental humidity on resin curing. 4, in the surface treatment and pasting carbon fiber sheet before, should according to the reinforcement design of position line positioning. 5, resin prepared by the use of the product ratio should be placed in the provisions of the capacitance weighing 20, use a blender to uniform mixing to uniform color. Stir with the container and agitator can not have oil and impurities. Should according to the actual environment temperature determine each mixing amount of resin, and strictly control the use of time according to the use requirements.  
Two: construction preparation 1, should read carefully design and construction plans. 2, we should the actual condition according to the construction site and is reinforced concrete member, make the programme of construction and construction plan. Using the 3, deal with carbon fiber sheet, the resin, machines and tools for construction preparation work before. 
Three: 1, should remove surface treatment is reinforced component surface spalling, osteoporosis, honeycomb, corrosion deterioration of concrete, exposed concrete structure layer, and repair materials will repair the surface smooth. 2, should be designed according to the requirements of crack seam filling or closed treatment. 3, be pasted the concrete surface should call embarrassed smooth, remove surface laitance, oil and other impurities, until completely exposing new surface concrete structure. At the corner to lead angle paste processing of well polished into a circular arc shape, arc radius should not be less than 20mm. 4, concrete surface should be clean up and maintain the dry. 
Four: brushing process provisions bottom resin 1, according to the product suppliers to provide the base resin preparation. 2, the application of roller brush bottom resin evenly on the surface of concrete. Should be in contact with the surface of the resin to dry immediately after the next step in the process of construction.
Five: leveling treatment 1, should be established process technology products suppliers to provide the preparation of leveling material. Fill the flat 2, deal with the concrete surface depressions for stem material, and should not have edges and corners. The 3 corner leveling material, application of repair is a smooth arc, radius should not less than 20mm. 4, should be in the leveling material surface dry to touch immediately after the next step in the process of construction.  
six: pasting carbon fiber sheet 1, pasting CFRP shall meet the following requirements: (1) cutting to size of carbon fiber cloth design requirements: (2) technology provision shall be formulated product suppliers to provide diffuse stains resin and evenly to the desired location pasted; (3) with special along the fiber direction of the rolling roller for many times, in addition to squeeze the bubble, the impregnated resin is fully saturated with carbon fiber cloth. Do not damage of carbon fiber cloth rolling; (4) multilayer paste repeat the steps above, should be on the surface of the fiber impregnated resin refers to the next layer of paste immediately contact after drying; (5) on the surface of the last layer carbon fiber cloth evenly impregnated resin. 2, we should follow the steps of bonding carbon fiber board, (1) should be cutting to size carbon fiber plate design requirements, process according to the provisions of product suppliers to provide the preparation of adhesive resin; (2) the carbon fiber plate surface wipe clean and dust free. For pasting two layers, on both sides of bottom CFRP plate shall be clean: (3) should be immediately brushing adhesive resin carbon fiber board and wipe clean, layer should be a protuberance, the average thickness of not less than 2mm: (4) will be coated with a carbon fiber plate bonding resin gently pressed on the need to paste position. Using a rubber roller along the fiber direction steady compaction, the resin from both sides to ensure the overflow, dense no empty. When the parallel is pasted with a plurality of carbon fiber sheet, gap between the two plates shall be not less than 5mm; (5) two layers of carbon fiber sheet shall be continuous paste, paste. If not immediately paste, then start before pasting CFRP plate to deal with the underlying do cleaning work.
