材料導(dǎo)熱系數(shù)總表(比較齊全)

1、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(shí)內(nèi)，通過1平方米面積傳遞的熱量，單位為瓦/米度（W/mK,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(shí)，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(guó)國(guó)家標(biāo)準(zhǔn)規(guī)定，凡平均溫度不高于350時(shí)導(dǎo)熱系數(shù)不大于0.12W/(mK)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(shí) kcal/(mh )卡 / 厘米秒 cal/(cms )瓦 / 米 KW/(mK)
