Análisis de la influencia del espesor de la capa de adhesivo termofusible sobre la fuerza de unión

2021/03/18

Cuando el grosor deladhesivo layer has a certain relationship with the adhesivo force, the greater the adhesivo force of the hot melt adhesivo, the greater the adhesivo force, while the adhesivo layer is too thin or even has only one adhesivo surface, the greater the adhesivo force , And when the adhesivo layer is too thin or even has only one adhesivo surface, the adhesivo force will be smaller.

     If the adhesivo layer is too thick, the probability of defects in the adhesivo layer will increase. When external forces are applied, stress concentration will easily occur around these defects, and the hot melt adhesivo layer will break. The proper thickness of the hot melt adhesivo can make the two surfaces of the adherend fully wet, so that the adhesivo layer can form a complete adhesivo layer between the two adherends.
