On the significance of adhesive strength

In general, the adhesive structure always requires the best mechanical properties when the bonding is completed. At present, the main indicator to measure the mechanical properties of the adhesive system is the bonding strength. Therefore, when purchasing adhesives, it The bond strength is a very important factor to consider. The adhesive strength of the adhesive refers to the stress required to cause the adhesive in the adhesive and the adherend to be damaged under the action of external force or in the vicinity of the adhesive. The adhesive strength is also called the adhesive strength. Adhesive strength is the stress required when the adhesive system is destroyed. Its size depends not only on the adhesive force, the mechanical properties of the adhesive, the nature of the adherend, the bonding process, but also on the form of the joint and the stress (type, Size, direction, frequency), environmental factors (temperature, humidity, pressure, medium) and test conditions, experimental technology and so on. It can be seen that the adhesive strength is only one of the important factors that determine the adhesive strength, so the adhesive strength and adhesive strength of the adhesive are two completely different concepts and should not be confused.
