高效率低碳微波製程應用於高肉厚橡膠製品之研究

傳統實心輪胎因厚度較大，硫化製程多採用電熱或蒸汽加熱，熱量需由外向內傳導，易產生「外熱內冷」現象，造成硫化不均、製程時間延長及能耗偏高。本研究採用最佳化微波腔體模擬設計技術與低碳微波預熱技術，利用微波的體積加熱特性直接作用於橡膠分子偶極，將電磁能轉換為熱能，使天然合成橡膠（NBR）輪胎材料由內而外同步升溫，有效避免橡膠材料受熱不均之現象，可使整體橡膠硫化製程時間縮短約40~50%，同時維持橡膠交聯均勻性、硬度與耐磨耗性能，並顯著降低單位產品能耗。微波加熱技術突破厚件製品熱傳限制，兼顧效率提升與節能減碳需求，具備高度產業應用潛力。

Traditional solid tires are typically vulcanized using electric or steam heating, where heat transfers from the outside inward, often causing uneven heating, longer processing times, and high energy consumption. This study applies optimized microwave cavity design and low-carbon microwave preheating. Microwave volumetric heating directly converts electromagnetic energy into heat within rubber dipole molecules, enabling uniform inside-out heating of NBR tire materials. As a result, vulcanization time is reduced by about 40~ 50%, while maintaining uniform crosslinking, hardness, and wear resistance, and significantly lowering energy consumption. Microwave heating overcomes heat transfer limitations in thick products and offers strong potential for efficient, low-carbon industrial applications. Microwave heating technology overcomes the heat transfer limitations of thick rubber products, achieving both improved efficiency and reduced carbon emissions, demonstrating strong potential for industrial applications.
