The rapid development of structural reinforcement technology puts forward higher requirements for the research of new technologies and new materials. Because of its simple process and fast anchoring, it is safe and reliable. It can be widely used in reinforcement construction techniques such as structural reinforcement and strengthening, new and old structural connection, buried steel reinforcement and post-buried steel components. So what is the difference between inorganic and epoxy resin planting bar adhesive?
Inorganic planting bar adhesive consists of Portland cement, micro-expansion special cement, superplasticizer and retarder. Inorganic reinforced rubber is rarely used in engineering, and important large-scale projects are forbidden to use it.
Epoxy reinforced adhesive is mainly composed of epoxy resin and curing agent. It is a two-component epoxy adhesive with A, B components. It has thixotropic properties, high tensile and shear strength, excellent aging resistance and fatigue resistance, and excellent load- displacement characteristics, through the bonding and locking function, to achieve the embedded effect. The glue requires a small hole diameter, and the vertical hole, the horizontal hole and the inverted hole can be easily implanted. Generally, the diameter of the borehole is d+2∽8mm, and the anchoring depth is 15d. The anchoring force value of the planted steel is generally greater than the yield value, which satisfies the requirements of Grade A adhesive of Concrete Structure Reinforcement Design Specification GB50367-2006. It is currently a designated product in important fields including nuclear power, high-speed rail and subway.
NJMKT brand epoxy resin planting bar adhesive is a modified epoxy adhesive that can be easily injected with a glue gun. It is suitable for anchoring projects. It has been successfully used in important large projects such as Tianwan Nuclear Power, Suzhou Metro, Kunyu High Speed Rail and Shanghai Disney.
