Construction process of steel-bonding adhesive

Surface treatment of concrete and steel plate → Selection and preparation of fixed components → Ingredient and glue mixing of structural adhesive → Coating structural adhesive and pasting → Fixing, pressurizing, and curing → Removing fixed and pressurized components → Quality inspection and anti-corrosion.

Construction instructions of steel-bonding adhesive

1. Surface treatment

(1) Treat the concrete surface to make the bonding surface free of oil, dirt, and dust.

(2) Grind the concrete bonding surface, remove the 1 - 2mm surface layer, remove the dust, and wipe it clean with acetone.

(3) Rust removal treatment for the surface of the bonded steel plate.

2. Glue mixing

(1) The filler in the glue is easy to precipitate, but it does not affect the strength. Stir it evenly before use. (When stirring, the A and B components cannot use the same stirring rod)
