Guangdong carbon fiber adhesive is used for tensile, shear and seismic reinforcement of structural members

Modified epoxy resin carbon fiber adhesive fiber adhesive is a two-component modified epoxy adhesive
It is a special adhesive for pasting carbon fiber sheets and is widely used in structural reinforcement

1、 Product features
· The primer has low viscosity and strong permeability, can well penetrate into the pores of the concrete surface, and has strong adhesion with the concrete

· Repair glue has moderate viscosity, good thixotropy, no flowing, easy to apply and scrape, and high strength

· Impregnating adhesive has good wettability and permeability, which is consistent with carbon fiber sheet
The material has strong mechanical properties and excellent durability
The adhesive also has good thixotropic performance and good suspension, so that the fluidity is small during the construction of vertical plane

· The cured adhesive layer has excellent physical and mechanical properties and strength and toughness

· Anti aging, medium resistance (acid, alkali, water) good performance

· It can cure at room temperature, does not contain volatile solvents, is non-toxic, environmentally friendly and has high bonding strength

· The glue proportion is wide, and can be adjusted appropriately at different ambient temperatures
It is convenient to use and convenient for on-site operation

application scope
· It is used for bottom coating on the surface of reinforced members

· Used for repairing and leveling surface defects of reinforced components

· It is used for dipping and pasting carbon fiber, glass fiber and other fiber sheets on the surface of reinforced components

4、 Construction technology
· Clean the surface of the substrate: polish the bonding roller to remove the laitance and loose layer on the surface, expose the new surface, blow off the dust with an air compressor, and then remove the dirt with acetone

· Brush the primer, weigh the required amount of primer according to the proportion and mix it fully
Evenly apply the mixed primer on the concrete surface with a roller or brush
Carry out the next process immediately after the primer is dry (usually 2 hours)

· Level the base surface, weigh the required amount of glue according to the proportion and mix it fully
Use a scraper to repair and level the surface of defective concrete components with the mixed leveling glue
After the glue is solidified, Immediately carry out the next process construction

· Paste the carbon fiber sheet and cut the carbon fiber cloth according to the design requirements
Weigh the required amount of glue according to the proportion and mix it fully
Evenly apply the mixed impregnation glue to the pasted part and paste the carbon fiber cloth
More glue can be applied at the lap and corner
Roll several times along the fiber pile direction with a smooth roller
Squeeze out bubbles to make jgn802 impregnation glue fully soak the carbon fiber cloth
Do not damage the carbon fiber cloth during rolling
Repeat the above steps for multi-layer pasting
Apply a layer of impregnation glue evenly on the surface of the last layer of carbon fiber cloth

· Reference dosage: jgn802 modified epoxy resin carbon fiber adhesive: 0
