Analisis pengaruh ketebalan lapisan perekat lelehan panas terhadap kekuatan ikatan

2021/03/18

Saat ketebalan fileperekat layer has a certain relationship with the perekat force, the greater the perekat force of the hot melt perekat, the greater the perekat force, while the perekat layer is too thin or even has only one perekat surface, the greater the perekat force , And when the perekat layer is too thin or even has only one perekat surface, the perekat force will be smaller.

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