Many times, the bonding effect of glue is not due to the glue itself, and external factors affect the effectiveness of the glue. Firstly, we should understand why adhesives tend to age in order to find solutions. By using adhesives, we can gain many benefits, including enhanced design choices, improved product durability, and increased operational efficiency.
& nbsp; & nbsp; & nbsp; Many times, the bonding effect of glue is not due to the glue itself, and external factors affect the effectiveness of the glue. Firstly, we should understand why adhesives tend to age in order to find solutions. By using adhesives, we can gain many benefits, including enhanced design choices, improved product durability, and increased operational efficiency. However, despite today's advanced adhesive technology, bonding will naturally fail. What should we do in such situations?
& nbsp; & nbsp; Reason 1: There is contamination on the bonding surface
& nbsp; & nbsp; & nbsp; If the surface is contaminated, it may cause the adhesive to age. The types of contamination include grease, oil (including oil on the skin), and other impurities. Therefore, it is important to ensure proper cleaning of the equipment and proper preparation of the surface before placing the adhesive. If automatic dispensing technology is used, it must also be kept clean throughout the entire production process. This is because some adhesives can partially cure in the dispensing device, resulting in a decrease in adhesive strength. Surface treatment can include various washing and abrasion treatment methods, but the optimal method depends on the specific chemical properties of the substrate and adhesive
& nbsp; & nbsp; Reason 2: Adhesive technology
& nbsp; & nbsp; & nbsp; The reason for this bonding failure largely involves whether the adhesive is manually applied. The adhesive needs to be applied in a consistent and correct amount to achieve the best bonding strength, and if done manually, it may be difficult as too much or too little adhesive in an area can lead to bonding failure. To ensure uniform coverage, make sure to apply the adhesive to the same location every time
& nbsp; & nbsp; Reason 3: Substrate issue
& nbsp; & nbsp; & nbsp; If the substrate and adhesive are incompatible, adhesive failure may occur. For example, some plastics may seep into the surface over time and cause adhesive aging in certain areas. In addition, some surfaces may cause the adhesive to cure improperly. To avoid this situation, it is important to ensure the compatibility of the substrate and adhesive before choosing
& nbsp; & nbsp; Reason 4: Environmental factors
& nbsp; & nbsp; & nbsp; Certain environmental conditions can increase the likelihood of adhesive failure, thereby affecting curing, including but not limited to high humidity, carbon dioxide, pH levels, oxygen, etc. For some adhesives, these conditions may cause slower curing. For others, it can speed up the process. In order to achieve appropriate bonding under different environmental conditions, it is more important to fully understand how the adhesive performs in a given application and conduct thorough testing
