Application scope
Generally used for the external reinforcement of reinforced concrete components by scraping and pasting steel plates.
, used for self-adhesion or mutual adhesion of metal, non-metallic and polymer materials in civil structural engineering.
, used for reinforcement construction of bonding steel plates and beam surfaces to improve load capacity.
Product Description
Steel adhesive is a two-component, modified epoxy, highly thixotropic, viscous paste structural adhesive.
Main features
High strength, especially steel-steel bonding shear strength and steel-concrete bonding shear strength.
, Unique high-performance polymer toughening modification technology, impact resistance and fatigue resistance, especially suitable for dynamic load reinforcement such as bridges.
, aging resistance, acid resistance, alkali resistance and water resistance.
Technical performance
The technical performance of steel-gluing adhesives are in line with the national standard "Code for Design of Reinforcement of Concrete Structures" ( ) and the Ministry of Communications industry standard "Code for Design of Reinforcement of Highway Bridges" (/ ) grade adhesive requirements.
, can also be designed and developed according to special requirements to meet the special requirements of customers.
Usage methods and construction points
Surface treatment
Surface treatment is the most critical process, including the treatment of the bonding surface of reinforced components and the bonding surface of steel plates.
The bonding surface of concrete components should be treated according to the following four conditions according to the newness, solidity, dryness and wetness of the component surface
For the bonding surface of very old and dirty concrete components, You should first use a hard-bristled brush dipped in high-efficiency detergent to remove surface grease and dirt, then polish the bonding surface and blow off the powder particles with oil-free compressed air to remove the thick surface layer until the new surface is completely exposed (after treatment, if the surface If it is seriously uneven, you can use epoxy repair mortar to repair it. Wipe the adhesive surface clean before pasting and let it dry completely.
If the concrete surface is not very dirty or old, you can directly polish the bonding surface, remove the thick surface layer, use compressed air to remove dust, wipe it clean and wait until it is completely dry.
For the new concrete bonding surface, first use a wire brush to brush off the loose scum on the surface, polish it to remove the laitance and dust, then wipe it clean and wait until it is completely dry.
For concrete components with high humidity or concrete components within three months of age, since the bonding strength of general resin adhesives on wet base layers will be greatly reduced, in addition to meeting the above requirements, it is still necessary to Concrete elements must be artificially dried.
