Adhesive strength

Under normal circumstances, 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, so when the adhesive is purchased, it is The bond strength is a very important factor to consider. The adhesive strength of an adhesive refers to the stress required to break the adhesive or adherend in the adhesive part or its vicinity under the action of an external force. The adhesive strength is also referred to as the adhesive strength. Adhesion strength is the stress required when the adhesive system is broken. 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 the form of the joint and the force conditions (kind, Size, direction, frequency), environmental factors (temperature, humidity, pressure, medium), test conditions, and experimental techniques. It can be seen that the adhesive force is only one of the important factors that determine the bonding strength. Therefore, the adhesive strength and adhesive strength of the adhesive are two completely different concepts and must not be confused.
