It is used for impregnation and adhesion of carbon fibre, glass fibre and other fibre sheets on the surface of reinforcement components.
Product Features
It has low viscosity, good wettability, strong permeability, and can penetrate well into the pores of concrete surface.
It has good compatibility with carbon fibre.
The physical and mechanical properties of the cured adhesive layer are excellent, strong and have a certain degree of elasticity.
The comprehensive performance is excellent anti-aging, acid and alkali resistance, good water resistance, does not contain volatile solvents, safe and non-toxic.
Scope of Application
Carbon fibre pasted in concrete, masonry and wood elements is mainly used in reinforcement to resist tensile forces, and is generally applied to tensile areas of flexural members and beams, shear areas of beams and columns, and perimeter bundles of columns or bridges.
Proportion of Glue
Ratio of dispensing rubber for groups A and B: 2:1
Workflow
Concrete Surface Preparation - Priming - Levelling - Carbon Fibre Cloth Adhesion - Curing and Maintenance - InspectionI. First,Concrete surface treatment
Concrete surface should be chiselled away from the whitewash layer, grease, dirt, and then use the angle grinder to grind away 1-2mm thick surface layer, concrete component corners should be chamfered to deal with the grinding is completed with compressed air to blow clean floating dust, and finally wipe the surface with cotton cloth dipped in acetone to keep it dry and standby. If there are cracks in the concrete to be reinforced, it should be filled with Juntendo cans and then reinforced.
Second, levelling construction
Precipitated concrete surface porosity defects should be used levelling adhesive fill level, the existence of recessed parts, will be prepared levelling adhesive with a scraper embedded scraping for repair and filling, template joints and other parts of the height difference between the application of levelling adhesive to fill to minimise the height difference. Corner of the treatment, the application of levelling adhesive will be repaired as a smooth arc, the radius is not less than 20mm. levelling adhesive shall be cured [curing time depending on the temperature of the site, in order to finger touch dry is appropriate, generally not less than 2 hours), Wan can then proceed to the next process.
Third, the primer construction
Construction, the primer A, B two components according to the prescribed proportion of glue weighing, pour into a clean container and mix well, mixing the best along the same direction, try to avoid mixing air bubbles. Brush or roller in the concrete surface evenly coated, after the glue surface dry, depending on the specific circumstances of multiple brush, but the thickness of the coating does not exceed 04mm, and shall not miss the brush or there is a flow, bubbles, such as curing glue (curing time depending on the temperature of the site, to the finger touch the dryness of the desirability of the general not less than 2 hours), and then proceed to the next process. Each time the preparation of the glue should be used up within the period of application of the glue.
Caveat
The construction environment is ventilated and dry, and the concrete surface is clean and free of oil.
Wear gloves, masks, goggles, helmets and other protective equipment during construction.
If it accidentally gets on the skin or clothes, use industrial alcohol and a lot of water to rinse.
If accidentally eaten or splashed into the eyes, seek medical advice immediately.
