本研究將具有高加熱效率的微波導入塑料鞋材加工製程以縮短製程時間。實驗結果顯示以圓心兩步法之製程只需加熱140秒,比傳統製程的13分鐘以上,大幅縮短了55倍以上的加工時間,且此製程各處貼合效果都能超過商業剝離強度2kgf/cm的標準,整片試片剝離強度最低值仍有2.07 kgf/cm,成功地將微波應用在改善全回收貼合鞋材。另一方面,本研究也將微波貼合製程運用HFSS-Icepak建構出微波加熱模型,成功模擬出試片於腔體內旋轉加熱後的溫度分布,並以實驗驗證其溫度誤差僅在10%附近。在碳纖維複合材料的微波加工方面,將熱塑性的聚丙烯與碳纖維複合材料置於40 mm空心公模並放入發泡板後,以兩金屬轉盤間距為56 mm、不鏽鋼檔板距離在50 mm或是100 mm的控制條件下,都能讓微波均勻在100 mm×100 mm的面積上進行加熱程序,靜止樣品高溫區模擬與實際量測的誤差僅6.8%。最後,本研究也進行腔體調整來設計出最佳的腔體加工設備。實驗結果顯示,將微波腔體上方原為不鏽鋼轉盤改成聚丙烯材質,不鏽鋼檔板直接放在不鏽鋼保護套上方,能讓電場均勻分布至整個試片。重新設計過後的機台,可應用到環氧樹脂與玻璃纖維複合材料、聚碳酸酯與碳纖維複合材料以及橡膠產業上,達到加工時間短、能源運用效率提高及降低成本的效果。此系統也有相當潛力能被應用在更多的加工製程。
In this study, high heating efficiency microwaves were introduced into the plastic shoe material processing process to shorten the processing time. The experimental results show that the two-step process only needs to be heated for 140 seconds, which shortens the processing time by more than 55 times compared with the traditional process, and the test piece can exceed the commercial standard peel strength of 2kgf/cm. Using HFSS-Icepak to construct a model to simulate the temperature distribution of the test piece after rotating and heating in the cavity, the error is only about 10%. In the microwave processing of carbon fiber composite materials, after PP-CF is placed in a mold with a 40 mm hollow male and an EVA foaming plate, the distance between the two metal turntables is 56 mm, and the distance between the stainless steel baffle plates is 50 mm or 100 mm. The microwave heating program is performed uniformly on an area of 100 mm×100 mm, and the simulation error of the static sample high-temperature zone is only 6.8%. Finally, the best cavity processing equipment was designed, the stainless steel turntable in the microwave cavity was changed to polypropylene, and the stainless steel baffle was placed directly above the stainless steel protective cover so that the electric field could be evenly distributed across the Epoxy-CF. The redesigned machine can also be applied to epoxy resin and glass fiber composite materials, polycarbonate and carbon fiber composite materials, and the rubber industry.
