Abstract
The release of acetone solvent from the adhesive layer is an important part of the curing of DW-1 adhesive, and this process is mainly affected by its diffusion behavior. In order to predict the volatile residual amount of acetone in the adhesive layer, the diffusion phenomenon of acetone solvent was studied. Based on Fick’s law, a numerical model of solvent diffusion is established, and a calculation method of mutual diffusion coefficient suitable for the system of acetone and DW-1 glue is proposed; a simulation model is constructed to reveal the competition mechanism of volatilization phenomenon and diffusion phenomenon, and analyzes the acetone in the diffusion process Distribution status. The theoretical guidance for reducing the residual amount of acetone is provided by this research in the adhesive layer.
