Epoxy resin adhesive is one of the most common auxiliary materials in contemporary resource development. It caters to the needs of social resource construction and exploration. The application of epoxy resin adhesives in water conservancy projects aims to clarify resource advantages and promote continuous innovation of industrial resources.
Epoxy resin adhesives have very strong doping power, corrosion resistance and dielectric properties. Applying it to concrete in water conservancy projects can reinforce the role of reinforced concrete. Through experimental research methods, research embedded results show that epoxy resin adhesives and cement-based adhesives have better performance; when the temperature reaches a certain range, the performance of the epoxy resin resin adhesive will decrease; when exposed to high temperature, the longer The longer it comes, the more the compressive strength, modulus of elasticity and the tensile strength of the concrete decrease.
Epoxy resin adhesive is an excellent blending material. Ordinary epoxy resin adhesives are more sensitive to moisture and can be replaced by longer interfaces or underwater crack strength, and are only suitable for curing under dry conditions. The special epoxy resin adhesive replaced by underwater curing agent and water-absorbing filler is sufficient to cure under dry conditions, and can also be cured under water, and still has higher elongation strength and better water resistance after curing. Due to the wide range of material sources, simple formula and convenient construction, a wide range of water conservancy projects are used in the reinforcement and plugging.
The viscosity of the adhesive is directly proportional to the shear failure stress. Therefore, it is necessary to compound the high-viscosity and low-viscosity curing agents to produce an adhesive with low viscosity and large shear failure stress; the gel time is about 1h. , The gel time of 301P and 810P curing agents is exactly 1h; the shear strength of 301P and 810 curing agents is the largest; the compressive strength of adhesives is generally higher than the shear strength. Combining the performance of 7 kinds of curing agents, it can produce 301P curing agent supplement, which is suitable for supplementing water conservancy projects, can carry out good supplement performance, and is also beneficial to construction.
