Overview of Setting Resin Anchoring Agent

The anchoring agent in building is also called structural anchoring adhesive, which is used for anchoring steel bars and bolts.

Main technical properties of anchoring agent

1. The early strength of the product is high, and the strength can reach 12-18mpa in half an hour, 25-30mpa in 4 hours, and 50-60mpa in 28 days;

2. Good construction performance, not limited by the site;

3. No corrosion effect on steel bars, good impermeability;

4. This product has a slight expansion, the linear expansion rate is 3‰;

Anchoring dosage form number specification

Type gauge (mm) Curing time (min) Compressive strength (MPa)

Fast MNH32/250 5-10 4 hours 22

Medium speed MNH32/250 10-20 4 hours 20

Slow MNH32/250 30-60 24 hours 30

According to design requirements and engineering needs, different specifications can be produced

Method of using anchoring agent

A. Clean the anchor hole with water or wind, put the appropriate amount of anchoring agent into the water, soak for 1-2 minutes, so as not to bubble (note: soaking time should not be too long).

B. Feed the anchoring agent into the anchor hole within the calibrated initial setting time, and then insert the anchor rod.

In the process of coal mining, bolt is commonly used to support the roadway, which is a kind of adhesive that combines the bolt driven into the coal and rock mass.

Duration of anchorage agent

When the ambient temperature is 20~25℃, the storage time is not less than 3 months.
