一u0026nbsp;Composition and characteristics:
u0026nbsp;
Carbon fiber impregnated adhesive (sticky fiber composite structural adhesive) seriesA、BTwo-component modified epoxy resin Adhesive is the main type of adhesive used to reinforce fiber composite materials (such as carbon fiber cloth, carbon fiber board, glass fiber cloth, aramid fiber cloth, etc.). It is often used with structural reinforcement primer (priming glue) and concrete repair glue (structural reinforcement and leveling) Glue), respectively used in different procedures of reinforcement construction. MeetGB50728'Technical Specification for Safety Appraisal of Engineering Structure Reinforcement Materials',GB50367'Code for Design of Reinforcement of Concrete Structures' andJTG/T J22'Code for Design of Highway Bridge Reinforcement'AGrade glue technical requirements, passed national standards90Wet and heat aging performance test.
The main features are:Building reinforcement reinforcement material reinforcement plan
◇u0026nbsp;high strength, high toughness, aging resistance ;
◇u0026nbsp;Strong bonding ability with concrete and fiber;
< strong style='padding: 0px; margin: 0px; text-align: left;'>◇u0026nbsp;There are two types of products to choose from: stick fiber cloth (cloth glue) and stick fiberboard (board glue);< /span>
◇u0026nbsp;The cloth glue is a strong thixotropic fluid, which is easy to wet and penetrate into the fiber, and it will not drip when applied on the upper side;< /span>
◇u0026nbsp;Slab glue is a highly thixotropic paste, easy to apply and scratch, and does not hang during construction;
◇u0026nbsp;It has a wide range of adaptability and can be well adapted to different brands of fibers;
◇< /strong>u0026nbsp;Cure at room temperature, without volatile solvents.

Four applicable ranges:
1.Scope of application This process is suitable for the reinforcement of concrete beams, slabs, columns and other structures by pasting carbon fiber cloth; glass fiber, aramid fiber, etc. can be used for reinforcement, anti-corrosion, and waterproof construction. Refer to this method. Reinforcement plan for building reinforcement materials

3.Construction essentials:
(1)u0026nbsp;< span style='padding: 0px; margin: 0px; text-align: left; transition: all 0.2s linear 0s; font-family: Song Ti;'>Reinforcement design
Structural inspection and reinforcement design should be conducted by professionals, and reinforcement construction should be conducted by a professional construction team. Prior to construction, the line should be positioned according to the reinforcement design.
(2)u0026nbsp;Concrete surface treatment
The painting of the concrete surface to be reinforced The layer and loose parts are thoroughly removed and then polished; if the steel bars are exposed, the steel bars should be derusted first, and then repaired with leveling glue; the protruding parts of the surface should be smoothed with a cutter or a grinder. Convex corners at cornersR≥25mm above, for concave corners Filling; if there are cracks in the reinforced concrete, it should be filled with structural grouting glue before reinforcement. The surface of the concrete must be clean, dry and free of oil stains. If there is water seepage in the reinforced part, it should be treated with hydrophobic, water stop and drying first, and the surface of the concrete that needs to be reinforced should be wiped clean with acetone or alcohol.

When the primer is dry, you can proceed to the next process. . The glue solution prepared each time should be used up once within the pot life of the glue.
