Epoxy Resin Adhesive Anchoring
The planting bar glue has high bonding strength, like pre-embedded, solidification at room temperature, small shrinkage during hardening, good temperature resistance, can be welded after embedding, good durability, weather resistance, aging resistance, medium resistance (acid, alkali, Water) Good performance, excellent toughness and impact resistance after curing, no volatile solvents, non-toxic and environmentally friendly, wide distribution ratio of A and B groups, convenient construction and other characteristics.
Drill holes according to the regulations → clean the holes with a brush and an air cylinder → stir the A and B components separately → prepare the planting glue in proportion to fully stir and mix → use a special tool to inject the glue into the hole → rotate the steel bar or screw into the hole Medium → curing → quality inspection
1. According to the requirements of the engineering design, drill holes in the corresponding position in the base material (such as concrete). The hole diameter, hole depth and steel bar diameter should be determined by professional technicians or field tests.
2. Use a special air cylinder, brush or compressed air machine to clean up the dust in the borehole. It is recommended to repeat it no less than 3 times. There should be no dust and water in the hole.
3. Derust the surface of the steel bar and wipe it clean with acetone or alcohol.
4. Mix components A and B in a ratio of 2:1 until they are completely uniform, and pour them into the borehole.
5. Rotate the steel bar and insert it to the bottom of the hole to ensure that the glue overflows at the hole and pay attention to prevent glue leakage. Whether the glue layer is full or not will directly affect the anchoring force.
6. During the curing process, the anchors should avoid disturbance. After gelation, it will be fully cured at room temperature for 1-2 days.
7. Visually check whether the curing is normal. The planting bars of important parts need to be subjected to on-site pull-out tests to check whether the anchoring force meets the design requirements; the construction of the next process can be carried out after being qualified.
