Resin Anchors For Coal Mine Metals

Product Description

Resin anchoring agent is made of unsaturated polyester resin, curing agent, accelerator and other auxiliary materials, according to a certain proportion of the viscous form of anchoring bonding material, by polyester film split packaging in the form of medicine rolls, with fast curing at room temperature, high adhesive strength, reliable anchoring force and durability and other good performance

Specifications and Parameters

Note: Specified under (22±1) C ambient temperature conditions.

Product features:

1. Fast load bearing, anchoring performance similar to steel pre-buried parts. It has the characteristics of "two fast and one high", i.e. fast curing time (speed adjustable), fast strength growth and high strength. After installation, it can not only bear the load in time, but also has large anchoring force.

2. Resin anchoring agent adaptability, bonding object wide. Bonding shaped, complex large thin plate structure, can anchor a variety of wood, metal, fiberglass body and other rigid objects.

3. Good fatigue strength. Resin anchors can be widely used for structural reinforcement, rock support, equipment foundation fixing, dam crack repair and high-rise building exterior stone dry hanging, metal or curtain wall frame installation and fixing.

4. Water-resistant resin anchoring agent in addition to the above characteristics, when there is the presence of water, has the characteristics of fast enhancement, high strength, to avoid the impact of water on the curing rate of resin anchoring agent, compressive strength and anchoring force.

Usage:

1.According to the surrounding rock lithology, geological conditions, design anchor support parameters, according to the requirements of construction operations to select the resin anchoring agent specifications, models.

2.For the convenience of word anchor installation, the depth of drilling hole should be 60~80mm less than the length of anchor.

3.After the anchor hole is drilled, before installing the anchor, pressurized air should be used to remove floating dust and water in the hole.

4.Installation of anchor rods: use the anchor rod to slowly send the anchoring agent to the bottom of the hole, then start the agitator to drive the rod to rotate, advance the rod to the bottom of the hole at a uniform speed, mix and stir the two components of the anchoring agent, and play the role of anchoring. Select the rotational speed of the mixing machinery ≥ r/min, and the mixing time is operated according to the time specified in Table I. It is strictly prohibited to turn on the mixer in the case that the anchoring agent is not delivered to the bottom of the hole.

5.After the end of mixing, wedge the rod in time, and do not make the rod move during the waiting time to ensure the quality of anchoring.

6.After meeting the waiting time specified in Table I, the nut can be tightened on the pallet, and the designed anchoring force can be reached after reaching the bearing time.

7.Anchoring agent must be carefully checked before use color and feel, soft texture, appearance intact can be used. If there is hardening, caking, rupture, deterioration and other abnormal phenomena, prohibit the use.

8.After the installation, the anchoring quality should be checked, and the anchoring force should be tested according to the regulations. If the anchoring force is found to be not in accordance with the requirements, remedial measures should be taken.
