Detailed Product Description: | Technical Advisory Lo: 133-8150-4949 My company specializes in carbon fiber, carbon fiber plastic, just glue stick, anchorage glue, pouring plastic and other reinforcement materials production and sales, to undertake strengthening works, with special professional qualifications reinforcement system using CFRP Imported 12K carbon filament weaving loom on the special surface treatment by coupling activity, easily dipping structural adhesive affinity, high tensile strength. The technical indicators are to meet "reinforced concrete structure design code GB50367-2006" and "carbon fiber reinforced structural technical specification sheet member CECS146: 2003" requirement. With good performance, to be applied in many fields. Purpose: CFRP structure supporting the use of plastic become carbon fiber composite materials for reinforced concrete structures, wooden structure, which can effectively improve the bearing capacity, seismic performance and durability member. Engineering problems dealing with the following outstanding options: 1, building use load increase; 2, works using functional changes; 3, material aging; 4, concrete strength grade is lower than the design value; 5, structural cracks handling; 6, bad Environmental service component repair, protective. Other uses: satellites, aircraft, rockets, sporting goods, industrial products, and many other fields. Features: 1, high tensile strength carbon fiber, equivalent 10∽15 times that of ordinary steel; 2, acid, corrosion-resistant, suitable for service in harsh environments; used in conjunction with a structural adhesive, can prevent harmful media infiltration of the internal structure of the protective effect; 3, the proportion is 23% of the steel, the basic components without increasing weight, does not change the member section size; 4, flexible winding, for all types of surfaces, shaped reinforcement member is more significant advantage; 5, can be arbitrarily cut, easy to paste, easy to guarantee construction quality. Without large-scale construction equipment, can be extended to any overlap bond, no fire operations, short construction period. Carbon fiber cloth Technical indicators Appearance black carbon filament density (g / cm3) 1.8 beam yarn linear density (g / 1000m) 800 each bundle containing monofilament yarn number (root) 12,000 yarn bundle Model 12K standing Width (mm) 100, 150,200,300,400,500,1000,1500 standing Specification (g / m2) 200,300 calculated thickness (mm) 0.111 (200g / m2), 0.167 (300g / m2) factory packaging (m / volume) 100 anti- tensile strength (MPa)> 3400 elastic modulus (MPa)> 210000 Elongation (%)> 1.5 Precautions direct contact with the human body scraps irritating :( Note CFRP sample preparation using fabric glue stick structure, 25 ℃ Curing 120 hours, 25 ℃ test) CFRP CFRP instructions are used in conjunction with the supporting structural adhesive to form a high-performance composite materials. Process: component surface treatment → Paste surface repair leveling (if smooth, this step can be omitted) → primer rubber → unloading (according to the actual situation and the design requirements, this step may be omitted) → configuration surface glue and cutting CFRP → Paste CFRP curing → → → test component surface treatment 1.1 Maintenance 1. The member surface should be clean, dry, the corner should be chamfered, grind (positive angle) or fill out the (negative angle) radius of not less than 20mm After a smooth arc, 2. Paste surface repair leveling (if smooth, this step can be omitted) 2.1 cellular component surface, pockmarked face, convex parts repair structural adhesive filled with components, repair glue curing (drying appropriate finger touch about 5 hours), may be the next process. 3. Configure primer 3.1. Take a clean container (plastic or metal pots, without oil, water and impurities) and weighing scales, according to fabric glue to paste the bottom mix mixed and stirred with a stirrer 5∽10 minutes to A Group B were mixed until uniform. The best stir stirring in the same direction to avoid the formation of air bubbles mixed with glue should now with the current. 3.2 with a brush, roller or plastic scraper glue evenly on the bottom surface of the component elements, be careful not to leak brush and avoid bubbles, such as finger touch dry cured glue to carry out a process under construction. 4. unloading (according to the actual situation and the design requirements, this step may be omitted) 4.1 to moderate unloading solid Hejia best, and can be lifted only live loads, such as staff, office equipment, etc., and to minimize the temporary construction loads . 4.2. The dead load unloading system can jack plate, consisting of ejector, the system is easy to control the size of the reaction force is applied to reduce the stress behind, more conducive to collaborative CFRP components with the original force, strengthening good effect. 5. Configure the surface glue and cutting 5.1 CFRP fabric glue stick surface for A, B two components can be mechanical agitation. A small amount can also be Φ6, Φ8 thin steel rod manual mixing. (Note: just tired of mixing knife, does not guarantee stir). 5.2 according to the design requirements of size with a sharp pair of scissors cutting CFRP, attention uniform, to avoid glitches. Should be in the smooth wood, cardboard, plastic sheeting on the crop, in order to maintain a clean cloth. 6. Paste the CFRP 6.1. The fabric glue paste evenly on the surface member is affixed to the site and CFRP, appropriate to apply some corner of the site. (75% of the surface of the gum paste applied in the CFRP surface, when the paste, the remaining 25% of the surface of the plastic coated on the outer surface of the carbon fiber cloth.) 6.2. The good rubber-coated carbon fiber cloth, after tension Paste Aligned with plastic scraper or roller (with a paint roller to remove lint outside it), repeatedly rolling in the same direction until the gum exudation. Then the outer surface of the carbon fiber cloth also face glue evenly and repeatedly rolling, so that two-way full structural adhesive infiltration CFRP. 6.3. If the multi-paste, until your fingers touch dry, the next layer of paste (Repeat step 5, step 6). 6.4. For CFRP lap, lap length of not less than 0.2 meters. 7. curing 7.1. If the curing temperature is about 25 ℃, 3 days to load. If the curing temperature is about 5 ℃, 5 days to load. 8. Inspection 8.1 when available test hammer tap or hand pressure judgment paste adhesive surface effect, the total effective area of ??not less than 95% of the bond, such as a slight hollowing (area less than 100cm2) can take the needle dispensing method remedy. If hollowing area of ??more than 100cm2, should be at the carbon fiber cloth hollowing resection stick up around the lap length greater than 0.2 m of CFRP blocks. 8.2 can also be used for an important component of the load detection, the general classification load to normal load standard value, the test results more intuitive, reliable, but higher cost, you need a jack or counterweight (used sandbags, bricks), percentage table, crack microscope. 9. Maintenance 9.1. Pasted after 48 hours, you can paint the M15 20mm thick cement mortar or blast protection. 9.2. Note that the initial setting of the outermost layer of glue should sprinkle a small amount of clean sand before or beans stone, stucco interface to facilitate binding. 10. Note 10.1 CFRP cutting with a sharp pair of scissors, note uniform, to avoid glitches; should be in the smooth wood, cardboard, plastic sheeting on the crop, in order to maintain a clean cloth. 10.2. To extend the CFRP lap length of not less than 200mm. 10.3. The product line is easy to produce debris, hairiness, if adhered to skin irritation and itching, if inhaled can cause throat, trachea, lung damage. So the best of overalls, gloves, masks, goggles and other construction. Construction finished with soap and water to clean the leak site. 10.4. Conductive carbon fiber, not in contact with the power supply. Floating in the air fluff, fluff it may cause a short circuit and electrical faults. 10.5 Shelf life: CFRP performance and stability, with almost unlimited shelf life (at room temperature, dry storage) Contact Mr. Fang Shiluo: 133-8150-4949 |
