これらの方法のうち、サンディング等による粗面化方法
は、作業上手間を要すうえ、サンディング等により発生
する削り粉を接着面に残存しない様にする必要がある。Among these methods, surface roughening methods such as sanding require work and time, and it is necessary to prevent shavings generated by sanding or the like from remaining on the adhesive surface.
もし削り粉を除去しない場合には、接着強度が著しく低
下する。又、削り粉の処理上も問題がある。If the shavings are not removed, the adhesive strength will be significantly reduced. There is also a problem in processing the shavings.
有機溶媒等による表面粗面化方法は、空気汚染による作
業環境の悪化、廃液の処理等の問題を生じている。Surface roughening methods using organic solvents and the like pose problems such as deterioration of the working environment due to air pollution and disposal of waste liquid.

It was thought that it could not be done.
さらに、紫外線照射法も表面ににじみ出た内部離型剤等
が接着を阻害するため、ＰＰＳの接着には有効でないと
考えられていた。Furthermore, the ultraviolet irradiation method was also thought to be ineffective for adhesion of PPS because the internal mold release agent etc. that seeped out onto the surface inhibited adhesion.
