In layman's terms, their differences can be seen from several aspects. One is the ratio of acidic oxidation, and the other is the ratio of alkaline oxidation. For example, basalt, its acidity coefficient needs to be greater than 1.8, and the national standard requirement also needs to reach above 1.8. The acidity coefficient is mainly linked to its service life. The larger the coefficient, the longer the service life. The acidity of slag rock wool board can only reach about 1.2. Therefore, from this data, it cannot be compared with basalt.
And to distinguish the differences between the two, first of all, it can be seen from the appearance. The appearance of basalt rock wool board is relatively flat and regular, and the fibers look relatively delicate. While slag is different, its fiber arrangement is irregular, and it will also prick hands. In terms of color, the color of rock wool is yellow, and the color is uniform, while slag is gray-white, and there will be uneven color. From the above two points, we can identify the differences between rock wool and slag.
Of course, in addition to appearance, they are also different in use. For example, rock wool boards can be used for external walls, but slag wool cannot. This is another difference caused by their own structural properties.
