“ Epoxy anchor adhesive is a post-anchor connection technology widely used in engi ”

Epoxy anchor adhesive is a post-anchor connection technology widely used in engineering circles. It uses a chemical adhesive—epoxy anchor adhesive to fix the ribbed steel bar and long screw in the drilled hole of the concrete base material to achieve anchorage to the connected parts.
There are many factors that affect the effect of epoxy anchor adhesive, such as the performance of epoxy anchor adhesive, drilling depth, dust, construction steps, and so on. Today we will talk about the importance of hole clearing.
In dry concrete with uncleaned holes, the bond strength of the colloid will decrease by 50%. Therefore, we should use an extended anti-shedding brush to take out the dust and debris in the hole, and then use compressed air to blow out the floating dust. Back and forth three times. Finally, wipe with absorbent cotton dipped in alcohol.
But can not be scrubbed with water, because alcohol is volatile, water is not volatile, and after scrubbing with water, the hole is not easy to dry.
