"熱絕緣體(thermal insulator)"指能夠顯著阻礙熱量傳遞的材料或物質。其核心原理是通過低熱導率的微觀結構抑制熱能傳導、對流和輻射。根據國家标準《GB/T 10295-2008 絕熱材料穩态熱阻及有關特性的測定》,理想熱絕緣體需具備孔隙率高于90%、孔徑小于空氣分子平均自由程等特征。
常見熱絕緣材料包括:
美國能源部研究顯示,優質熱絕緣體可使建築能耗降低40-50%。在工業領域,根據ASME鍋爐壓力容器規範要求,高溫管道必須使用經認證的陶瓷纖維絕緣層。當前材料科學前沿聚焦于真空絕熱闆(VIPs)技術,其熱阻值是傳統材料的5-10倍。
Thermal Insulator 的詳細解釋:
1. 基本定義
Thermal insulator(熱絕緣體)指能夠有效阻隔熱量傳遞的物質或裝置,其核心功能是減少熱傳導、對流和輻射。該詞由"thermal"(熱的)和"insulator"(絕緣體)組合而成,常見于工程、建築和材料科學領域。
2. 核心特性
3. 相關術語擴展
4. 詞源背景
"Thermal"源自希臘語"thermos"(熱),而"insulator"源于拉丁語"insula"(島嶼),引申為隔絕能量的裝置。兩者結合後,特指隔絕熱能的材料或結構。
