Electromagnetic heating system such as micro wave processing has evolved as a appealing technique to connect polymer substrates due to its ability to achieve noncontact, selective heat and localized melting. In microwave helped bonding procedure, two plastic layers including PMMA (polymethyl methacrylate) substrates can be fused by heat a thin layer of dielectric material placed between the polymer layers. To better be familiar with bonding procedure for polymer levels, a detailed assumptive analysis has become presented. Through this analysis, the bonding technique of polymer substrates has been patterned as a multilayered composite piece exposed to micro wave radiations. The electric discipline distribution along each part is computed from simplified Maxwell's formula under airplane wave settings, and the Poynting theorem is employed to find the volumetric power consumed by each layer. The absorbed power is then employed as the cause term in one dimensional, unsteady energy equation which is solved by geradlinig decomposition and separation

of parameters techniques. Finally, the closed form synthetic solution obtained from this research is used to analyze the effect of fabric properties on temperature circulation of polymer substrate (PMMA) with poly-aniline as more advanced sacrificial level. The research was performed at household microwave rate of recurrence (2. four GHz) with temperature based mostly dielectric homes for the two poly-aniline and PMMA levels. Our results show that dielectric properties, layer thickness, heat transfer coefficient and processing time have significant influence on the heating style. Results as well show the temperature from the PMMA base remained under the melting stage globally, except at the interface of the polyaniline layer because of its transparent nature to occurrence microwave rays at installment payments on your 4...
