Tel: 13918759739 Engineering CFRP specific steps: First, the general requirements: 1, bonding carbon fiber sheet reinforced concrete structure should be familiar with professional construction team completed the construction process of this technology, and programs should be reinforced repair and construction technology 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 the construction of supporting adhesive temperature. When the ambient temperature is below 5 ℃, should be used for low temperature heating using an adhesive or supporting action. 4, the construction should consider the adverse effects of humidity on the curing of the adhesive. 5, the front surface treatment and bonding carbon fiber sheet reinforcement design should be part of actinomycetes positioning. 6, when the adhesive preparation instructions for use should be weighed in the ratio specified in a container with a stirrer Stir until uniform color. Vessel and stirred with a stirrer without oil and impurities. It 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, construction plans should be carefully read. 2, should be based on the site and are reinforced concrete structures construction of the actual situation, to develop construction plans and construction plans. 3, carbon fiber sheet to deal with the use of matching adhesive, prepare equipment and other pre-construction preparations. Third, the surface treatment: 1, should be cleared by the reinforcing member surface flaking, loose, cellular, and corrosion deterioration of concrete, exposed concrete structure layer and surface repair of prosthetic material flat. 2, the design requirements of the cracks should be pouring or closed process. 3, is pasted concrete surface should be polished smooth, remove surface laitance, oil and other impurities, until completely exposed concrete structure of the new surface. Corner pasting lead angle to be processed and polished into a circular shape, an arc radius should be not less than 20mm, as shown at right. 4, the concrete surface should be clean and dry. Fourth, brushing primer: 1, shall be prescribed in the process of formulating product providers adhesive layer, according to the actual temperature determines the amount of plastic material. And strictly control the use of time, shall not exceed the applicable time use. 2, with a roller or brush the adhesive evenly on the bottom of the concrete surface, colloidal thickness not exceeding 0.4mm, and not leak brush, flow or air bubbles, the primer surface Tack immediately after the next process of construction. Fifth, the leveling process: 1, shall be prescribed in the process of preparation of product suppliers leveling material. 2, to deal with the concrete surface to fill the flat with a recessed portion leveling material without proper corners. 3, apply leveling material to repair the corner of a smooth arc, radius should be not less than 20mm. 4, leveling the surface should refer to the next step immediately touch dry after construction. Six CFRP SHEETS: 1, according to the design requirements with carbon fiber sheet cut to size, unless special requirements, Length of CFS should be less than 3 meters, when the carbon fiber sheet to a length greater than 3 meters, use simple roll core roll stand, at right FIG. Good cropping with carbon fiber sheet should pay attention to dust and protected against contamination and bent. 2, shall be prescribed in the process of preparation of product suppliers and impregnated with a special undercoat adhesive roll evenly to the site you want to paste in the lap, corner portions appropriate to apply some. 3, with a special carbon fiber cloth hairless roller surface repeatedly rolling in the same direction until the outer surface of the adhesive oozing carbon fiber cloth, to remove air bubbles, adhesive full penetration impregnated carbon fiber, carbon fiber sheet to not be damaged when rolling. 4, multi-paste repeat the above steps, it should refer to the fiber surface-impregnated adhesive to touch dry immediately after the next layer of paste; 5, in the last layer of carbon fiber cloth impregnated with adhesive surface evenly. When the surface protection surface protection when required, should be required to deal with the relevant specifications and ensure a reliable bond between the protective material 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, or taking reliable protective measures. 2, the construction process should avoid bending carbon fiber sheet. 3, carbon fiber sheet supporting the adhesive material should be stored away from ignition sources, avoid direct sunlight. 4, adhesive formulation and use of spaces should be 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 must not be mixed. Eight, inspection and acceptance: 1, before starting construction, should confirm that the carbon fiber sheet and matching adhesive bonded product certification, product quality and factory inspection report, the performance indicators should meet the requirements. 2, the use of carbon fiber sheet and matching adhesive bonded materials for concrete structures reinforcement and restoration, should be strictly in accordance with the relevant provisions of the construction process and carry out each step of the process of inspection and acceptance of concealed work. Such as construction quality can not meet the relevant provisions of the construction process and process requirements, should take immediate remedial measures or rework. 3, carbon fiber sheet design actually pasting area of ??not less than the amount of the positional deviation should be less than 10mm. 4, bonding quality 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 bonding area of ??not less than 95%. When CFRP hollowing area is less than 10000㎜2 when dispensing needle can be a way to remedy. Hollowing larger than 10000㎜2, it is desirable carbon fiber sheet hollowing at the removal and re-paste overlap the same amount of carbon fiber sheet, lap length is not less than 100mm. 5, if necessary, carbon fiber sheet and matching adhesive bonded materials sampling and testing site.
