材料導熱系數(shù)總表比較齊全

1、定義：導熱系數(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）。導熱系數(shù)與材料的組成結(jié)構(gòu)、密度、溫度等因素有關(guān)。 非晶體結(jié)構(gòu)、密度較低的材料，導熱系數(shù)較小。材料的含水 率、溫度較低時，導熱系數(shù)較小。通常把導熱系數(shù)較低 的材料稱為（我國國家標準規(guī)定，凡 平均溫度不高于 350 C時導熱系數(shù)不大于（m K）的材料稱為 保溫材料），而把導熱系數(shù)在瓦/米攝氏度以下的材料稱為高 效保溫材料。千卡/米時;ckcal/(m h - C )卡/厘米秒Ccal/(cm s C )瓦
