Studies on Adhesives

III. Analysis for the Adhesive Destruction Oscillograms of Novolak Resin

Abstract

Continued from the last paper, Oscillograms of adhesive destruction has been analysed and the results are derived as follows: The time of Momentary destruction (t_i) is about 0.01-0.03 sec, and the slight deformation (σ) of the adhesive layer (σ) is 0.1-1.8 it estimated as electric capacity change.Quantitative relations are not found between σ and t_i, adhesive strength (σ) and t_i, σ and deformation velocity (σ/t_i).The Ratio of deformation to adhesive lager (σ/σ×100 (%)) linearly increases with testing temperature.
