Mr. Tang, General Manager - Tel. * * * The carbon fiber cloth 200/300 produced by our company is made of high-quality imported Dongli/Taili carbon fiber (PAN based carbon fiber with tow of 12k or below) raw materials, and is woven with advanced domestic equipment and exquisite technology. The product performance exceeds the national standard G 367-2013《 concrete Code for Design of Structural Reinforcement and GB/T 21490-2008 Carbon fiber sheet 》Requirements for performance index of medium carbon fiber sheet. In recent years, carbon fiber reinforcement is a new reinforcement technology developed in the United States and Japan and applied in civil engineering. This method uses carbon fiber fabrics arranged in the same direction, and uses epoxy resin Sticking to the surface of the concrete structure, using it to closely adhere to the concrete surface, so that the two as a new whole, under common force, is a very simple and excellent reinforcement method. Different from the traditional bonded steel reinforcement, carbon fiber reinforcement achieves the purpose of reinforcement without increasing the load of the structure. 2. Features (1) Simple construction (no need for large construction organizations and revolving materials), fast, no wet water operation, easy operation, and good economy. (2) It can improve the strength and corrosion resistance of the structure (3) It can be suitable for structural reinforcement of any shape. (4) Wide application scope and short construction period. (5) This method uses carbon fiber fabrics arranged in the same direction, and uses Epoxy resin adhesive Paste on the concrete structure Table 1. Product characteristics of carbon fiber cloth: 1. Light material. Height: tensile strength 3200~3800MPa, the same section steel products 10 times more, specific gravity 2.0~3.0g/cm3, single layer thickness 0.15~0.2mm, it is pasted with the structure with adhesive to form an integral whole, the thickness is only about 2mm, basically without increasing the member section, while the increase of the dead weight of the structure can be almost ignored, which can reliably ensure that it works together with the original reinforced concrete members, and obtain good repair results; 2. Acid and alkali resistance, corrosion resistance, suitable for service in harsh environments; When used together with structural adhesive, it can prevent harmful medium infiltration and protect the internal structure; 3. The specific gravity is 23% of steel, which basically does not increase the dead weight of the component and does not change the section size of the component; 4. It can be bent and wound to form, and has more obvious advantages for strengthening various curved surfaces and special-shaped components; 5. It can be cut arbitrarily, pasted easily, and the construction quality is easy to guarantee. No large construction machines and tools are needed, and the lap bonding can be extended at will. There is no open fire operation, and the construction period is short. 6. Convenient construction: it occupies less space, does not need large machines and tools, does not need wet work, does not need hot work, does not need on-site fixed facilities, and has high construction efficiency. 7. High durability: no rust, very suitable for use in high acid, alkali, salt and atmospheric corrosive environments, and also has the advantages of high fatigue relieving strength, wear resistance, and aging relieving. 2、 Construction method (step) 1. Construction preparation 1) Before construction, carefully read the design construction drawings, and set out and position the reinforcement parts according to the design drawings. 2) The construction scheme and construction plan shall be prepared according to the actual situation of the construction site and the reinforced component concrete. 3) The carbon fiber sheet used shall be matched resin Machines and tools shall be well prepared before construction. 2. Concrete surface treatment 1) The deteriorated concrete such as spalling, looseness, honeycomb and corrosion on the surface of the reinforced member shall be removed to expose the concrete structure layer. 2) The surface of the reinforced member shall be polished and leveled, and the surface laitance, oil stain and other impurities shall be removed until the new surface of the concrete structure is completely exposed. The corner sticking part shall be treated with a guide angle and polished into a circular arc with a radius of no less than 20mm. The surface shall be repaired with repair materials. 3) The cracks shall be grouted or sealed according to the design requirements. 4) After the surface is polished, a strong blower or Vacuum cleaner Completely remove the surface dust and keep it dry. 3. Prepare and brush the base resin 1) Prepare the base resin according to the process regulations provided by the product manufacturer. 2) Should use roller Brush the bottom resin evenly on the concrete surface. The next process should be carried out as soon as possible after the surface of the bottom resin is dried. 4. Leveling treatment of adhesive surface 1) Leveling materials shall be prepared according to the process regulations provided by the product manufacturer. 2) The concrete surface shall be repaired by wiping the floating dust off the surface. If there is a depression, the repair glue shall be used for leveling; If there is segment difference or corner, it shall be plastered into a smooth surface. 3) The corners shall be repaired into smooth arcs with leveling materials, and the radius shall not be less than 20mm. 4) Use a scraper with a blade width ≥ 100mm to fill, repair and level the pit. The leveling degree shall be subject to the visual inspection that there is no obvious scraper or smooth scraper trace. 5) The construction of the next process should be carried out as soon as possible after the surface of the leveling material is dry. 5. Cutting of carbon fiber cloth (board) 1) Cut the carbon fiber cloth according to the design size. Remember to meet the design size. Do not cut the carbon fiber cloth obliquely and prevent wire drawing. 2) Ensure that the direction of the cut carbon fiber reinforcement is consistent with the direction of the bonding part. 3) The cut and molded carbon fiber shall be clean and free from pollution. 6. Prepare and brush impregnating resin or paste resin 1) Carefully read the instructions before preparing adhesive. 2) Determine the amount of each time according to the pasting area to prevent failure and waste. 3) Use and prepare strictly according to the weight ratio. 4) It shall be prepared according to the manufacturer's mix proportion and process requirements, and shall be in the charge of a specially assigned person. The mixing shall be carried out in a clockwise direction until the color is uniform, no bubbles are generated, and dust and other impurities shall be prevented from mixing. 5) The prepared adhesive shall be used immediately. 7. Paste carbon fiber material and carbon fiber cloth 1) Wipe the concrete surface again before pasting carbon fiber to ensure there is no dust on the pasting surface. 2) When applying structural adhesive on the concrete surface, it must meet the requirements of stable, accurate and even application, that is, stable, appropriate application force, and try not to flow or fall off; Accurate, no control line can be painted; Evenly, the thickness is consistent within the painting range. 3) When pasting the carbon fiber cloth, it should also be stable, accurate and even. The core requirement is that the unwinding force should be appropriate to ensure that the carbon fiber cloth does not wrinkle, fold and extend smoothly. 4) The rolled carbon fiber cloth must be rolled from one end to the other. It is not suitable to roll and rub repeatedly at one part. During rolling, let glue penetrate the fiber cloth to make it saturated. When the carbon fiber cloth needs to be lapped, it must meet the specification requirements ≥ 100mm. 5) For multi-layer pasting, the next layer shall be pasted immediately after the surface of carbon fiber fabric is dry. If it is more than 40 minutes, wait for 12 hours before applying adhesive to paste the next layer.
