詳細介紹

耐火磚.jpg

耐火磚自身屬性

1、化學(xué)組成：主要成分決定該耐火材料的品質(zhì)和特點(diǎn)

2、體積密度：?jiǎn)挝惑w積重量，密度大，說(shuō)明致密性好，強度就可能高，但導熱系數可能就大

3、顯氣孔率：沒(méi)做具體要求，但作為生產(chǎn)廠(chǎng)家必須嚴格控制顯氣孔。

4、荷重軟化溫度：也叫高溫荷重開(kāi)始變形溫度，此參數很重要，標志材料耐高溫的抵抗能力

5、抗熱震性能：抗溫度急劇變化而不被破壞的能力

6、抗壓強度：承受（常溫）的最大壓力能力

7、抗折強度：承受剪切壓力的能力

8、線(xiàn)性變化率：也叫重燒線(xiàn)變化或叫殘余線(xiàn)變化，指每次在同等溫度變化中體積發(fā)生膨脹收縮的變化，如果每次膨脹收縮一樣，我們定義這樣的線(xiàn)性變化率為0
