Construction instructions
, Surface treatment
Treat the concrete surface to make the bonding surface free of oil, dirt and dust.
Polish the concrete bonding surface, remove the surface layer, remove dust, and wipe clean.
Carry out rust removal treatment on the surface of the bonded steel plates.
, Glue preparation
The filler in the glue is easy to precipitate, but it does not affect the strength. Stir evenly before use. (Do not use the same stirring rod when stirring components A and B.)
The glue is a dual component of A and B. Before mixing the glue, the glue of components A and B should be stirred evenly respectively, and then press the component A:Group B Weigh out the proportion of parts: and pour it into the prepared clean container, stir thoroughly until the color is uniform.
The amount of glue mixed each time should not be too much, generally no more than kilograms.
Paste, fix, and solidify
Apply the evenly mixed glue to the treated concrete and steel plate bonding surfaces respectively, thick in the middle and thin at the edges, and then bond the steel plate at the predetermined position.
After the steel plate is bonded, it should be supported immediately with clamps, bolts and other tools to hold it in place, and appropriately pressurized so that the glue is just squeezed out from the edge of the steel plate.
The operating time of this glue after mixing the two components A and B at room temperature is 3 minutes.
When the glue is at ℃, it can be cured in an hour. After removing the pressurized fixing device, it can be used under force after three days. When the temperature is lower than ℃, the curing time should be extended accordingly.
The minimum operating temperature of this glue is ℃. If it is lower than this temperature, necessary temperature-raising measures should be taken.
