Quality carbon fiber sheet to supply various provinces and cities nationwide, our carbon fiber inherent qualifications, quality assurance, 100% over the seizure, Division I is a professional carbon fiber reinforced construction and retrofitted with CFRP materials manufacturer . Specializing in a variety of high-performance carbon-fiber-reinforced materials, production and sales. And it has a special professional qualifications reinforcement. The major products include carbon fiber, carbon fiber, aramid fiber cloth, carbon fiber supporting resins and structural adhesive than the other materials. Architectural structure of the company independent research and development operations of reinforcement products, the national authority of the testing laboratories that product quality and performance in full compliance with national and industry quality standards. Retrofitting works have been widely used in industrial construction, civil construction, school reinforcement, roads, bridges, tunnels, water, coastal engineering and municipal infrastructure projects. Third, the company the advantage with carbon fiber sheet, light weight, easy construction. A substantial increase in component weight, does not change the member section size. 2, high tensile strength, high flexibility, can be obtained with the use of the same steel reinforcing effect. 3, anti-acid corrosion, high durability, can be used in any harsh environment. Used in conjunction with structural adhesive, to prevent infiltration of harmful media, the internal structure of the protective effect; 4, small thickness, easy to overlap. Can be bent winding, all kinds of surfaces, shaped and reinforcing advantage is more significant. 5, softness, and can be freely cut for beams, columns, plates, pipes and other shapes and wall components, tightly bonded and reinforced concrete surface, easy to guarantee construction quality. Without large-scale construction equipment, it can be bonded to any extension of the lap, no open flame operations. 6, supporting the superior permeability epoxy glue, construction convenient and shorter duration. 7, environmental pollution, residential construction is still available. 8, storage for a long time, long operational period. Fourth, the Carbon Fiber Cloth Scope: CFRP and supporting the use of carbon fiber impregnated plastic become carbon fiber composite materials for concrete flexural, axial compression, large eccentric compression and tension members reinforced reinforcement, wooden structure, can effectively improve Carrying Capacity member, seismic performance and durability. Dealing with the following issues outstanding engineering options: 1, building use load increase; 2, Project using functional changes; 3, material aging; 4, concrete strength grade is lower than the design value; 5, 6 structural cracks handling, harsh environment service component repair, protective. Sports fields, industrial products: 7, for other purposes. Fifth, the process and the process operating points can be summarized as follows: the construction preparation of concrete surface treatment → → brushing primer → member surface defects surface repair → CFRP → surface maintenance → Configuration → bottom leveling material or resin formulation → impregnating resin formulation operation Important: 1. Concrete Surface Treatment 1.1 will be incomplete concrete structures surfaces, damaged part removed. 1.2 pairs after tick chisel, clean up and missing parts components exposed tendons, repair, restoration. 1.3 crack repair: Aperture cracks less than 0.2mm, and brushing the surface with epoxy resin seal; cracks greater than 0.2mm pouring with epoxy. 1.4 polished: the component surface projection (transfer of parts of concrete structures, then hew templates, etc.) polished smooth surface of the component after the repair smooth as possible. 1.5 cleaning polished surface of the component and make it fully dry. 2. The defect site with a good brushing primer primer (binder), even with brushing the concrete surface at the defect site. 3. repair with epoxy putty repair surface defects on the surface of the component surface defects surface member is a very important step, points are as follows: 1 putty main agent, curing catalyst into, curing agent according to a predetermined ratio accurately weighed, into the container with a blender and mix well. 2 members dishing site filled with epoxy putty to repair to the surface roughness. When using epoxy putty in incomplete repair, to the temperature above -5 ℃, relative humidity less than 85% for construction. After Putty Scraping the surface roughening irregularities still exist, should then sanded smooth. 4. brushing primer with a good primer (binder), even with a roller brush to require bonded concrete surface. 5. Before CFRP CFRP material, you should first confirm the paste surface is dry. Temperature above -10 ℃, relative humidity RH> 85%, if no effective measures are not construction. To prevent damage to the carbon fiber, carbon fiber materials transportation, storage, cutting and pasting process. The steel ruler and wallpaper knife cut a predetermined size carbon fiber material, each length is generally not more than 6m appropriate. In order to prevent material damage in the storage process, cutting the amount of material shall be subject to the same day the amount of crop. Carbon fiber longitudinal joints must overlap at least 20cm. The parts should be painted resin, carbon fiber lateral overlap is not required. Its construction elements process is as follows: 5.1 paste resin main agent, a curing agent and a curing agent urged the proportion should be required to accurately weighed, into the container, blender and mix well. Reconcile the amount of time should be spent within the available time prevail. 5.2 pasting between carbon fiber and resin try not to have air. Available Rolla (special tools) along the fiber direction rolled several times in the carbon fiber material, immersing the resin infiltration of carbon fiber. 6. After curing CFRP material, nature conservation need 1-2 hours to reach initial cure should ensure free from outside interference and collisions during curing. 7. If the reinforcement member needs painting fire, the fire-resistant coating can be painted after the resin is cured. After the initial resin coating should be cured, and should comply with the relevant standards and regulations used in construction paints. Contact: (15900661030 Luo workers)
