材料導(dǎo)熱系數(shù)總表比較齊全

定義：導(dǎo)熱系數(shù)是指在穩(wěn)定傳熱條件下，1m厚的材料，兩側(cè)表面的溫差為1度（K,°C），在1小時內(nèi)，通過1平方米面積傳遞的熱量，單位為瓦/米?度（W/m-K,此處的K可用。C代替）。導(dǎo)熱系數(shù)與材料的組成結(jié)構(gòu)、密度、含水率、溫度等因素有關(guān)。非晶體結(jié)構(gòu)、密度較低的材料，導(dǎo)熱系數(shù)較小。材料的含水率、溫度較低時，導(dǎo)熱系數(shù)較小。通常把導(dǎo)熱系數(shù)較低的材料稱為保溫材料（我國國家標(biāo)準(zhǔn)規(guī)定，凡平均溫度不高于350°C時導(dǎo)熱系數(shù)不大于0.12W/（m?K）的材料稱為保溫材料），而把導(dǎo)熱系數(shù)在0.05瓦/米攝氏度以下的材料稱為高效保溫材料。千卡/米?時?C[kcal/(m-h-C)]卡/厘米?秒-C[cal/(cm-s-C)]瓦/米?K[W/(m?K)]焦耳/厘米?秒?C[J/(cm-s-C)]英熱單位/英尺時?°F[Btu/(ft-h-T)]12.78x10-31.161.16x10-20.6723601418.74.1872420.85982.39x10-3110-20.57885.980.239100157.81.494.13x10-31.731.73x10-21材料名稱導(dǎo)熱系數(shù)W/mK分類描述A356159A360113A38096ABS0.25-0.9ADC1296Ag銀429Ag99.9%411
