In the last issue, we introduced some similarities and differences between the reinforced adhesive and chemical anchors. Many people have indicated that they tend to choose to use the adhesive. Why is this happening? First let us analyze the advantages and disadvantages of the reinforced adhesive and chemical anchors:
In the previous article, we mentioned that the anchoring base is the same whether it is injection-type reinforced adhesive or chemical anchor. But the chemical anchors on the market are usually made by fast curing of unsaturated resin. The reinforced adhesive is usually made of modified epoxy resin. For example, Mankate MT-500 chemical reinforced adhesive is made of Taiwan South Asia epoxy resin. Unsaturated resins have great safety hazards to the structure. In addition, the adhesive can match different specifications of the screw, and the chemical anchor can only match the specification screw.
The chemical anchor bolts are generally thick and short. The anchor depth is shallow, and the adaptability to the cracks of the substrate is poor. The bearing capacity is low. It is not suitable for the structure of the tensile and edge sheared composite forces and the post-anchor connection of the lifeline engineering structural members. The reinforced adhesive is similar to the anchoring of the cast-in-place concrete, and the failure mode is easy to control. It is suitable for the anchorage connection of structural members and non-structural members with static-level seismic fortification strength ≦ 8 degrees.

However, there is now a new type of inverted cone chemical anchor (also known as a shaped chemical anchor), which is also a kind of inverted cone screw with reinforced adhesive. This chemical anchor is called a special inverted cone. The chemical anchor bolt avoids the shortcomings of the colloid of ordinary chemical anchor bolts, which is not resistant to damp heat aging and poor strength, and is a chemical anchor bolt which is widely used in engineering. Nanjing Mankate's inverted cone chemical anchor has passed the certification of 50 years of anti-moisture and heat aging. It is more suitable for projects requiring lifelong warranty, so that you don’t have worries.
Although in most cases the advantages of the reinforced adhesive are higher than the ordinary chemical anchors, sometimes the chemical anchors have the advantage that the reinforced adhesive does not have. Therefore, the selection of suitable reinforcing materials is the key point. Both Mankate Reinforced adhesive and chemical anchor bolts are all produced with high-quality raw materials, which have received good response in the market.
