Detailed Product Description: | Carbon fiber reinforcement technology specific steps: First, the general requirements: 1, CFRP sheets reinforced concrete structure should be familiar with professional construction team completed the construction process of the technology, and should reinforce the repair plan and construction technical measures. 2. Carbon fiber reinforced construction must follow the steps were: 3, the construction should be at least 5 ℃ ambient temperature conditions, and shall comply with construction adhesive supporting the use of temperature. When the ambient temperature is below 5 ℃, should be used for low temperature environment, supporting the use of adhesives or heating treatment measures. 4, the construction should consider the adverse effects of humidity on the curing of the adhesive. 5, the front surface treatment and CFRP sheets, should be part of actinomycetes positioning reinforcement design. 6, when the ratio of the adhesive should be formulated for use in the weighing of products specified in a container, uniformly stirred with a stirrer until uniform color. Stir with a blender container and on without oil and impurities. Should be decided according to the actual ambient temperature adhesive mixing amount of each, according to the requirements of strict control of the use of time. Second, the construction preparation: 1, should carefully read construction plans. 2, according to the site and should be reinforced concrete structures construction of the actual situation, to develop construction plans and construction plans. 3, carbon fiber sheets used to deal with supporting adhesives, equipment and other pre-construction preparation work ready. Third, the surface treatment: 1, should be removed by peeling off the surface of the reinforcing member, loose, cellular, and corrosion deterioration of concrete, exposed concrete structure layer and surface repair with prosthetic material flat. 2, the design requirements of the cracks should be pouring or closed treatment. 3. Paste the concrete surface should be polished smooth, remove surface laitance, oil and other impurities, until completely exposed concrete structure of the new faces. Paste the corner office to be processed and polished lead angle into a circular shape, radius should be not less than 20mm, as shown at right. 4, the concrete surface should be clean and dry. Fourth, brushing primer: 1, should craft regulations formulated product suppliers underlying adhesive, according to the actual air temperature determines the amount of plastic material. And strictly control the use of time, shall not exceed the applicable time after use. 2, with a roller or brush the adhesive evenly on the bottom of the concrete surface and colloid thickness not exceeding 0.4mm, and not leak brush, flow or air bubbles in the primer surface Tack immediately after the next process of construction. Five, leveling treatment: 1, should craft regulations formulated product suppliers leveling material. 2, the response to fill the flat part of the concrete surface depressions with leveling material without proper corners. 3, at the corner of the application materials to repair leveling smooth arc, radius should be not less than 20mm. 4, the surface should be leveling material refers to the next step of the construction immediately after touch dry. Six, paste CFRP: 1, according to the size of the crop CFRP design requirements, unless special requirements, length CFRP should be within 3 meters, when CFRP length greater than 3 m, core application simple roll-up stand, at right Figure. CFRP good crop should pay attention to dust and protected against contamination and bending. 2, shall be prescribed in the process of preparation of product suppliers and impregnated with a special adhesive roll Shorthair want to paste evenly on the site, in the lap, corner site properly apply some more. 3, with a special roller hairless CFRP surface in the same direction until the adhesive oozing repeatedly rolling the outer surface of the carbon fiber cloth to remove air bubbles, so fully saturated with carbon fiber cloth impregnated with adhesive, not damage CFRP when rolling. 4, multi-paste repeat the above steps, you should refer to the fiber surface impregnated adhesive touch dry immediately after the next layer of paste; 5, the last layer of carbon fiber cloth impregnated with adhesive surface evenly. When the surface of the protective surface protection when needed, should be required to deal with the relevant norms, and to ensure a reliable bond between the protective materials and carbon fiber sheet. Seven, construction safety and precautions: 1, the carbon fiber sheet as a conductive material, construction of carbon fiber sheets should be away from electrical equipment and power supply, or take protective measures and reliable. 2, the construction process should avoid bending carbon fiber sheet. 3, carbon fiber sheet supporting the adhesive material should be sealed and stored away from ignition sources, avoid direct sunlight. 4, the adhesive formulation and use of premises should be kept well ventilated. 5, on-site construction work should take appropriate protective measures. 6, the adhesive should be preceded by the B component in the preparation Stir respectively, stirring utensils not mix. Eight, inspection and acceptance: 1, before the start of construction, make sure the carbon fiber sheet and matching adhesive bonded product certification, product quality and factory inspection report, the performance indicators should meet the requirements. 2, when the use of carbon fiber sheets and supporting material for adhesive bonded reinforced concrete structure repair, should be strictly in accordance with relevant provisions of the construction process and the process of each process conducted covert project inspection and acceptance. Such as construction quality can not meet the relevant provisions of the construction technology and process requirements, should take immediate remedial measures or rework. 3, carbon fiber sheets pasted area should be less than the actual amount of the design, position deviation should be less than 10mm. 4. Quality bonded carbon fiber sheets and concrete between the hammer and gently tap the available hand pressure or the surface of the carbon fiber sheet method to check, the total effective area of ??not less than 95% bond. When the area is less than CFRP hollowing 10000㎜2, we can use the needle dispensing way to remedy. Hollowing 10000㎜2 larger than when the carbon fiber sheets should hollowing at the removal and re-paste the same amount of overlap of carbon fiber sheets, lap length of not less than 100mm. 5, if necessary, carbon fiber sheet and matching adhesive bonded materials sampling and testing site. |
