在保温材料中，岩棉板和玻璃棉是市场上应用较多的两种，在建筑保温隔热、临时建筑保温、厂房保温隔热等场景应用尤其普遍，但是还是有很多人分不清岩棉板和玻璃棉的区别。其实简单的总结起来，岩棉板和玻璃棉的区别主要有以下几种。

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、生产原料不同。岩棉板是以玄武岩等岩石为主要原料，经高温熔融制成无机纤维；玻璃棉是以玻璃为主要原料，经过高温熔融制成玻璃纤维。

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、产品特性不同。岩棉板的容重密度相对较高，一般在45KG每立方到200KG每立方之间，且具有耐酸碱耐腐蚀等优点；而玻璃棉的容重密度比岩棉板会低一些，一般在10KG每立方到80KG每立方的范围，具有纤维韧性大等优点。

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、保温隔热性能不同。由于原料组成和产品特性，岩棉板具有耐高温的特点，高可耐高温600℃左右，而玻璃棉耐高温性能相对较差，约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、产品用途不同。由于二者耐高温性能不同，岩棉板多用于外墙防火保温材料、高温热力管道或者电力设备的保温隔热；玻璃棉多用于相对低温管道的保温，此外玻璃棉也常做吸声隔音棉，用在室内建筑隔音等。

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、成本价格不同。由于原材料成本不同，岩棉板的价格相对低于玻璃棉的价格。

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.
