& nbsp; & nbsp; Structural adhesive refers to an adhesive with high strength (compressive strength>65MPa, steel steel tensile bonding strength>30MPa, shear strength>18MPa), able to withstand large loads, and resistant to aging, fatigue, and corrosion. It has stable performance within the expected life and is suitable for bonding structural components that can withstand strong forces.

  & nbsp; & nbsp; Advantages of the use of structural adhesive



  & nbsp; & nbsp; Structural adhesive has high strength, peel resistance, impact resistance, and simple construction process. Used for bonding between the same or different materials such as metal, ceramic, plastic, rubber, wood, etc. It can partially replace traditional connection forms such as welding, riveting, and bolted connections. The stress distribution on the joint surface is uniform, and there is no thermal impact or deformation on the parts. Structural adhesive is widely used in engineering, mainly for strengthening, anchoring, bonding, repairing, etc. of components; Such as bonding steel, bonding carbon fiber, planting reinforcement, crack reinforcement, sealing, hole repair, road nail bonding, surface protection, concrete bonding, etc< br />


  & nbsp; & nbsp; Performance advantages of structural adhesive



  & nbsp; & nbsp; 1. Uniform stress distribution and high degree of freedom in material selection


  & nbsp; & nbsp; Firstly, when using structural adhesive, the stress can be evenly distributed throughout the entire bonding surface, eliminating the stress concentration problems caused by traditional methods such as spot welding, riveting, and bolt fixing. Therefore, lighter and thinner materials can be used without losing component strength. Secondly, it can effectively bond dissimilar materials and improve overall performance. Then, different materials can be bonded into laminated materials using structural adhesives, which can perfectly combine the strength and comprehensive performance of each material. At the same time, the toughness of structural adhesive can effectively solve the problem of inconsistent thermal expansion coefficients between different materials in applications, such as the bonding application between aluminum and glass. Structural adhesives can also serve as isolation layers to reduce or even eliminate electrochemical corrosion issues between different metals.

  & nbsp; & nbsp; 2. Reduce surface defects and save repair costs



  & nbsp; & nbsp; Components assembled with structural adhesive can maintain their integrity and eliminate surface defects caused by mechanical connection points and welding. Using structural adhesive bonding can greatly improve process design flexibility and reduce finishing work. Structural adhesives can also provide optimal fatigue performance, and the excellent toughness of adhesives allows for repeated stretching and recovery of components under repeated stress conditions. The energy absorption of the adhesive ensures that the bonded parts have up to 20 times the fatigue resistance of welded or riveted parts. The overall continuous connection formed by adhesive bonding of assembly components can ensure effective bonding and sealing in the working environment< br />


  & nbsp; & nbsp; 3. Reduce costs, environmentally friendly and efficient



  & nbsp; & nbsp; Choosing structural adhesive bonding can reduce costs while simplifying production processes. By using adhesive technology, the requirements for the substrate can be reduced, weight can be reduced, drilling, welding, screw fixation, and similar processes can be eliminated, ultimately achieving cost reduction while improving production efficiency. Only a small amount of training is required for operation, and there is no harmful solvent emission when using structural adhesive to bond materials that have undergone primer treatment or coating. Compared to traditional connection methods, structural adhesives have demonstrated outstanding advantages in cost, production efficiency, lightweight, and performance. In the vast majority of production applications, structural adhesives can provide higher strength and longer lifespan for components.
