碩士 === 國立高雄應用科技大學 === 化學工程與材料工程系碩士在職專班 === 104 === In this study, a water-based fluorocarbon resin (PVDF) was utilized as a coating-film material on the organic-inorganic hybrid coating to enhance the performance of screw surface. It shows the properties of weather resistance, anti-corrosion, chemical-resistance, water repellency and adhesion ability of the coating-films have significant improved. Moreover, it possesses a low curing temperature, which can reduce energy consumption in the coating process, and shorten the operation time. Additionally, the operation conditions of 90℃ and 15 min for fluorocarbon resin coating-films are available to complete the cure process as compared to those of the general cases of .180 ℃ and 30 min. Hence, this technology will reduce production costs and increase production line yields to improve product performance. Fluorocarbon resin coating can not only enhance the adhesion ability of stainless steel, but also the coating can be re-painted again. After re-coating, it can be further improve the properties of anti-corrosion and weather resistance. Because most of the coating-films cannot be applied at high temperature, it will carry out the dehydrogen process before the coating operation, in the traditional screw industry. Unfortunately, it will result in the manufacturing process is unable to continue production, and cause to waste of manpower. Fluorocarbon resin coating can overcome this drawback, dehydrogen process can be carried out after coating operations. It does not affect the product quality, and can also make the production line for continuous production and increase the yield.
