在保溫材料中，巖棉板和玻璃棉是市場上應用較多的兩種，在建筑保溫隔熱、臨時建筑保溫、廠房保溫隔熱等場景應用尤其普遍，但是還是有很多人分不清巖棉板和玻璃棉的區別。其實簡單的總結起來，巖棉板和玻璃棉的區別主要有以下幾種。

In the field of insulation materials, rock wool board and glass wool are two commonly used types in the market, especially in scenarios such as building insulation, temporary building insulation, and factory insulation. However, there are still many people who cannot distinguish the difference between rock wool board and glass wool. In fact, to sum up, there are several main differences between rock wool board and glass wool.

一、生產原料不同。巖棉板是以玄武巖等巖石為主要原料，經高溫熔融制成無機纖維；玻璃棉是以玻璃為主要原料，經過高溫熔融制成玻璃纖維。

1、 The production materials are different. Rock wool board is made from basalt and other rocks as the main raw materials, and is melted at high temperature to produce inorganic fibers; Glass wool is made from glass as the main raw material and melted at high temperature to produce glass fiber.

二、產品特性不同。巖棉板的容重密度相對較高，一般在45KG每立方到200KG每立方之間，且具有耐酸堿耐腐蝕等優點；而玻璃棉的容重密度比巖棉板會低一些，一般在10KG每立方到80KG每立方的范圍，具有纖維韌性大等優點。

2、 The product features are different. The bulk density of rock wool board is relatively high, generally between 45KG per cubic meter and 200KG per cubic meter, and it has advantages such as acid, alkali, and corrosion resistance; The bulk density of glass wool is lower than that of rock wool board, generally ranging from 10KG per cubic meter to 80KG per cubic meter, and it has the advantages of high fiber toughness.

三、保溫隔熱性能不同。由于原料組成和產品特性，巖棉板具有耐高溫的特點，高可耐高溫600℃左右，而玻璃棉耐高溫性能相對較差，約260℃左右。

3、 The insulation performance varies. Due to the composition of raw materials and product characteristics, rock wool board has the characteristic of high temperature resistance, with a high temperature resistance of about 600 ℃, while glass wool has relatively poor high temperature resistance, about 260 ℃.

四、產品用途不同。由于二者耐高溫性能不同，巖棉板多用于外墻防火保溫材料、高溫熱力管道或者電力設備的保溫隔熱；玻璃棉多用于相對低溫管道的保溫，此外玻璃棉也常做吸聲隔音棉，用在室內建筑隔音等。

4、 The product has different uses. Due to their different high-temperature resistance, rock wool panels are commonly used as fire insulation materials for exterior walls, insulation for high-temperature thermal pipelines, or electrical equipment; Glass wool is often used for insulation of relatively low-temperature pipelines, and it is also commonly used as sound-absorbing and soundproof cotton for indoor building sound insulation.

五、成本價格不同。由于原材料成本不同，巖棉板的價格相對低于玻璃棉的價格。

5、 The cost price varies. Due to different raw material costs, the price of rock wool board is relatively lower than that of glass wool.
