YJS-603 fiber leveling adhesive 
 Product Use: 
 Mainly used for concrete reinforcing carbon fiber structure of the base surface. High-viscosity putty, strong adhesive, anti-pay variable load performance is excellent, with excellent mechanical properties, good toughness, wear resistance, corrosion resistant, waterproof. 
 Technical indicators: 
 GB50367-2006 standard technical requirements. 
 The performance of the project test results of performance requirements (Class A rubber match) 
 The colloidal performance colloidal tensile strength (Mpa) 32.4 ≥ 30 
 Colloidal bending strength (Mpa) 40.6 ≥ 40 and not brittle (cataclastic) destruction 
 Concrete pull the bond strength (Mpa) 3.03, and the concrete cohesive failure ≥ 2.5, and cohesive failure of concrete 

 Use the methods and precautions: 
 YJS-603 leveling adhesive A and B during storage and transport will produce precipitation, respectively Stir prior to use hand drill. 
 2, the YJS-603 leveling glue Group A: B = 3:1 ratio uniform mixing. 
 3, the product density of 1.40 ~ 1.60g/cm3 (cured), the mixed use of time of about 30 ~ 60min (depending on environment 
 Temperature). The gel time of about 1.5 to 3 hours. 
 Storage: 
 The product can be stored below 40 ℃ ambient temperature, the shelf life of 24 months. 
 2, the product is solvent, storage should be away from open flame heating device. 
 3, The product is packaged 30kg to +10 kg / group. 

 Construction specifications 

 Construction conditions: 
 1, the construction surface should be clean and dry. 
 2, the construction temperature should be greater than 15 ° C, less than 40 ℃. 
 3, is strictly prohibited in the rainy outdoor construction. 
 4, the relative temperature is greater than 85% or concrete surface condensation on occasion, does not allow construction. 
 Construction Technology: 
 1, the primary requirements: the bonding surface must be smooth, solid, free of impurities, repair glue has hardened, and the surface is dry, no dew 
 Frost and so on. 
 2, the gel: calculate the dosage according to the bonding area, accurate and said to take the A, B in a clean container, stir evenly. 
 Tuned glue should be run out in the applicable period. 
 3, brushing glue: proportionally mixed YJS-602 carbon fiber underfill directly brushing the concrete base, concrete surface 
 Gel full. Hardening after the next process. 
 4, carbon fiber: 
 ① with a stiff brush will be a good tune YJS-601 impregnated with glue evenly brushing the adhesive surface, the gel content must be adequate, full brushing 
 About 400-600g/m2. 
 ② to cut a good carbon fiber cloth is affixed to the concrete paste surface, the use of hard rubber stick or plastic scraper back and forth RCC to promote carbon fiber 
 Straight, extended, full penetration of the adhesive carbon fiber cloth length up joints take the length of 10-20 mm. 
 ③ brushing part of the binder in the carbon fiber surface, continue reciprocating scratch RCC, driven out of the bubble, uniform coverage of the carbon fiber and adhesives 
 Cloth. Brushing is about 200g / ㎡. 
 ④ put it aside for 1-2 hours to refer to dry, repeat the RCC may cause bubbles to eliminate carbon fiber float or stagger, bonding is not real 
 And so on. 
 (5) multi-layer sticky, you can repeat the above operation. 
 ⑥ adhesive curing, is pasted on the surface of carbon fiber to scratch a layer of glue. 
 Note: 
 1, with plastic, should be properly ventilated environment. 
 2, the operator to use safety glasses to wear protective masks. 
 3, rain, frost and fog weather may not outdoor construction. 
 4, carbon fiber is conductive fiber, construction, operation must be away from power, to avoid electric shock casualties. Outdoors near the 
 (Wires, etc.) during the construction of the electrified body, if the wind should stop construction, carbon fiber cloth is the wind blowing contact with electrical conductors and accidents. 
 5, the fiber direction of carbon fiber cloth in one direction, unit weight, thickness, tensile strength, elastic modulus of the indicators must comply with 
 The relevant requirements.
