How to choose rock wool fireproof sandwich panel?

Do you often feel at a loss when choosing rock wool fireproof sandwich panels? As a core material, rock wool is closely related to the overall quality of the product. Here I summarize some methods for you from the perspective of how to identify the quality of rock wool. Let's take a look at how to choose rock wool sandwich panels.

Identification of rock wool quality methods

1. Distinguish from the color and uniformity: the general color of high-quality rock wool is earthy yellow, and the color distribution is relatively uniform. The color of inferior rock wool is not pure, and the distribution is uneven.

2. Distinguish from the slag content: the slag content of high-quality rock wool is small and fine, and it is not sticky when touched by hands. Its raw materials are processed from basalt and diabase. The slag content of inferior rock wool is increased, and it is mostly processed by mixing blast furnace slag and other metallurgical slag.

3. Test the water repellency: Sprinkle a certain amount of water on the rock wool board to see the water permeability of the rock wool. Generally, high-quality rock wool has better hydrophobicity, and the larger the surface area that is not penetrated, the better its hydrophobicity, and it is high-quality rock wool. Inferior rock wool has good water permeability and poor water repellency.

4. Test fire resistance: rock wool has fire resistance, heat insulation and other properties. Take a small amount of rock wool and burn it with fire to observe the burning situation. The rock wool that cannot be burned is high-quality rock wool, and the rock wool that can burn is low-quality rock wool.

After learning the above four methods, everyone will know how to make a reasonable choice when choosing rock wool fireproof sandwich panels. Knowing these details can help you avoid a lot of losses.
