Application of Adhesive Quality Management System in Sealing Technology

Sealing technology is a technique that prevents solid particles, liquids, and gases from leaking from the joint surface of components, or prevents external impurities such as liquids and gases from entering the interior of components. Sealing technology is widely used in various industries, such as the sealing of car windows in rail vehicles, the sealing of car engines, the sealing of wind turbine gearboxes, and the sealing of flanges for various pipeline connections. It can be said that sealing technology has penetrated every aspect of our lives.

Conventional sealing techniques include sealing gaskets, sealants, and other technologies. In gasket technology, in addition to conventional pre formed rubber gaskets, there are also silicone gaskets that are cured on-site using adhesive coating technology. In addition, commonly used sealants include silicone, modified silane adhesive, anaerobic adhesive, etc. Therefore, the application of bonding technology in the field of sealing is also very extensive, and improving the bonding quality helps to enhance the sealing quality of products.

Adhesive technology belongs to a special process and requires a specialized quality management system to control the adhesive quality. Taking the sealing of railway vehicle windows as an example, in the early days, due to the lack of attention paid to the bonding of sealant, the adhesion of car windows caused problems such as fogging, bubbles, and whitening inside the window glass after long-term operation. Yifa Bonding & Composite Research Institute is a leader in China's adhesive quality management system. For over a decade, Yifa has introduced adhesive standards such as EN17460/DIN6701 and ISO21368/DIN2304 into China. EN17460/DIN6701 adhesive quality management system is applicable to the rail transit industry, while DIN2304 adhesive quality management system is applicable to general industries outside the rail transit industry. After years of verification, the scale of EN17460/DIN6701 and DIN2304 adhesive quality system certification continues to expand. Yifa Bonding & Composite Research Institute has always been committed to helping China's manufacturing industry establish and improve technical standards in the field of adhesive applications. At the same time, through EAB training, EAS training, and EAE training, it has trained a large number of adhesive operators, technicians, and engineers in China, greatly enriching the domestic adhesive talent. Yifa Bonding & Composite Research Institute has been committed to helping improve the quality of adhesive sealing in various industries.
