Henkel technology helps to build environment-friendly composite vehicles

in the automotive industry, the use of light-weight structure provides a solution for the development of more economical and environmentally friendly vehicles. The more steel components replaced by lighter materials such as aluminum, the lighter the weight of the car, the better the effect of fuel saving and emission reduction, and improve the driving performance of the car at the same time. The structural characteristics and working principle of the tns-ez1a torsion tester developed by Henkel can help realize the permanent bonding between different lightweight materials that cannot be thermally welded. In addition, the company also produces various surface treatment products and systems, which can achieve the best results with only a small amount of chemicals. These technologies can help reduce material consumption, thus reducing production costs, while also helping to protect the health of relevant staff

the automobile industry is under heavy pressure in manufacturing light-weight vehicles, reducing fuel consumption and reducing environmental burden. This is a challenge for car designers. One way to deal with this is to build the car body by pretreatment and bonding different lightweight materials. Henkel is a global leader in adhesives, sealants and surface treatment solutions. It has always been committed to continuously developing and improving its products and technologies to help automobile manufacturers reduce production costs and material consumption, and/or create a safe production environment. Ingeo 3d850 is the basic resin model for 3D printing wire. For drivers, joints bonded with adhesive also have safety advantages, because these joints can absorb a large part of impact energy in the event of a car collision

the lightweight construction adopted by cars such as the Porsche 911 GT3 cup racing car is achieved through the use of alternative materials such as aluminum and composite materials. Composites based on carbon or glass fibers are becoming more and more important in modern high-performance applications, especially because they have the characteristics of light weight and high strength

compared with riveted or welded cars, cars widely bonded with adhesives during assembly have better crash test results. Dr. Stefan kreiling, head of European automotive product development at Henkel, explained: "Because the bonded joints will deform when impacted, and the deformation can absorb part of the collision energy. The use of adhesives for bonding during body assembly has many advantages: adhesives can increase the rigidity of the car, seal seams, reduce welding, and improve the corrosion resistance of the car. In addition, special adhesives used in body structure and general assembly also help to reduce noise."

Henkel has developed a two-stage process for the pretreatment of hybrid material body. In this phased process, the phosphating layer is no longer formed on aluminum, while the traditional phosphating can be carried out on steel and galvanized steel. By dividing the conversion treatment into two stages, only in the second stage after passivation, aluminum materials obtain the best preliminary treatment effect by forming zirconium conversion layer. This process can ensure that the body has high-quality corrosion resistance and excellent paint adhesion

continuous further development ensures that the pretreatment process can be continuously optimized in terms of quality and environmental protection: reduce energy consumption and the use of chemicals, such as fluoride or nitrite, which is subsequently converted, so as to help automobile manufacturers adopt sustainable manufacturing methods. Eliminating nitrite can avoid the release of nitrogen oxides and greatly improve the health and safety of the workplace. Similarly, the wastewater produced in this process does not need to be detoxified. The significant reduction of phosphate sludge can have a positive impact on the reduction of waste footprint, help to reduce treatment costs and reduce the cleaning of processing plants
