碩士 === 國立交通大學 === 機械工程學系 === 100 === Roll Forming is an important process in the domain of the polymer processing , simply is widely used in manufacturing processes to increase the life of plates and film . In recent years , various rolling processes for forming polymer film have been developed . However, as with the product thickness decreases , achieving the required accuracy is extremely challenging . This study analyzed polymer film characteristics in terms of roll parameters , film thickness , the response rate of film and bubble generation . Roller parameters were compared between different phenomena as an important indicator of the roller for use in , future designs for improving operation and maintenance . This study also designed new polymer material rolling equipment to achieve uniform thickness in rolling process . Operational parameters analyzed for the roller included the cooling temperature of roller , roller speed and the roll gap between the rollers . The objective was to optimize parameters needed to achieve a good surface quality and a uniform thickness in the polymer film . The experimental results show that , given a similar roll gap and roller surface temperature , the difference in improvements at the ends increases as the roll speed of the film specimen decreases . Given a similar roll gap and roll speed of the film specimen , overall uniformity of roller thickness increases and response rate decreases as the surface temperature of the roller increases . Additionally , as the roll gap decreases , the difference in thickness at the ends of the specimen decreases . The experimental results of this study provide a reference for improving roller devices and polymer roll accuracy .
