Determination of the Complex Dielectric Permittivity Industrial Materials of the Adhesive Products for the Modeling of an Electromagnetic Field at the Level of a Glue Joint
To achieve out this work we were interested in the study of microwaves techniques and also of the measurement of complex relative dielectric permittivity. It is important to measure this dielectric permittivity for the used adhesive before subjecting it to electromagnetic energy.
This prediction enables us to avoid an exothermic phenomenon due to the brutal rise in the temperature in the joint of adhesive. However, these results are used calculations program, to trace cartography of the electric field and of a temperature gradient in standardized test-tubes. At the end of this step, we have physical and experimental tools that can be used in the study of an optimized process using the microwaves. We check also the strong absorption of energy on the level of joint of adhesive (attenuation electric field), that the microwaves make it possible to well polymerize the adhesives with less times and low energy consumption without rise in prejudicial temperature of the parts to be stucked.
