& nbsp; & nbsp; Epoxy resin adhesive, as a new type of chemical material, is playing an increasingly important role in various industries and fields. This type of adhesive is used for bonding various materials and can partially replace traditional mechanical processes such as welding, unloading, and bolt connections. Moreover, due to the emergence of this material, a new type of lightweight and high-performance material has been developed, such as epoxy fiberglass reinforced plastic, epoxy carbon fiber reinforced composite materials, plastic steel (glass) composite pipes, epoxy polymer cement, etc< br />


  & nbsp; & nbsp; Epoxy adhesives have penetrated into various fields, such as the manufacturing of aircraft in the aviation industry, assembly in the automotive industry, manufacturing of light industrial machinery, insulation packaging in the electronics industry, reinforcement and maintenance of buildings, and repair of highways and airports. Epoxy adhesives not only have poor adhesion to non-polar plastics such as polyolefins, but also have excellent adhesion properties to various metal materials such as aluminum, steel, iron, copper, non-metallic materials such as glass, wood, concrete, as well as thermosetting plastics such as phenolic, amino, unsaturated polyester, etc. And in this regard, Cosmore has done a very professional job, focusing on the research of adhesives and providing integrated adhesive application solutions. Widely applicable, it can be used in industries such as new energy, military, medical, aviation, shipbuilding, electronics, automobiles, instruments, power supplies, high-speed rail, and communication.

  & nbsp; & nbsp; Application of epoxy adhesive in the field of construction

  & nbsp; & nbsp; Epoxy adhesive is widely used in the construction industry for bonding steel reinforcement of various components, including repairing bridges, reinforcing damaged beams and columns in old factories, extending columns, bonding cantilever beams, extending cement pile heads, bonding cow legs, etc. China is located in a seismic prone geological structure zone, and previous buildings had low seismic design levels. According to reports, 1.4 billion square meters of old buildings in China need to be reinforced and renovated. The application technology of construction adhesive can solve many problems that traditional building materials and processes cannot solve, such as the extension of cement pile heads. The welding method requires advanced welders to ensure the verticality of the pile heads, but the adhesive junior worker can operate it after training. When bonding steel beams, there is no need for welding technology, which saves equipment and has no fire problem. The steel bonding reinforcement performance is good, and the fracture bearing capacity can be increased by 2 times.

  & nbsp; & nbsp; Application of epoxy adhesive in the automotive field

  & nbsp; & nbsp; The main use of epoxy adhesives in the automotive industry is the increasing variety and dosage of body adhesives, which are characterized by improved oil surface bonding performance; Single group differentiation, able to be stored at 40 ℃ for six months; Before complete curing, it can withstand phosphating treatment without seepage or pollution to the electrophoretic paint; For high-strength structural adhesive.
 
  & nbsp; & nbsp; Application of epoxy adhesive in aviation field

  & nbsp; & nbsp; Epoxy adhesives are mainly used in the aviation and aerospace industry to manufacture honeycomb sandwich structures, fully bonded sheet metal structures, composite metal structures (such as steel aluminum, aluminum magnesium, steel bronze, etc.), and composite structures of metal polymer materials. They are generally structural adhesives, which have become one of the foundations of the entire aircraft design. For example, a Boeing 747 aircraft requires 2500m2 of adhesive film, and the adhesive area of a Trident aircraft accounts for 67% of the total connection area. For a certain type of supersonic heavy bomber, the adhesive wall panel reaches 380m, accounting for 85% of the total aircraft area, of which the honeycomb structure accounts for 90%, and the amount of adhesive used exceeds 40kg per aircraft.
