Information
(1) Similarities
a. They are all fibrous heat-insulating products made by centrifugation at high temperature;
b. The same product standard "Rock wool, slag wool and their products GB/T11835-2007 for thermal insulation" shall be implemented in the industrial field;
c. Implementation of the same product standard in the construction field (except for external wall insulation) "Rock wool and slag wool insulation products for construction" GB/T19686-2005;
(2) Difference
a. Different raw materials: rock wool uses natural ores such as basalt (or diabase) as the main raw material; mineral wool uses industrial waste slag such as blast furnace slag as the main raw material;
b. The fiber mechanical properties, temperature resistance and chemical stability of rock wool are better than those of mineral wool;
c. Mineral wool contains more alkaline compounds, and its volume stability and water resistance in a humid environment are worse than rock wool;
d. The acidity coefficient of mineral wool is lower than that of rock wool, and it is worse than rock wool in terms of weather resistance and service life;
e. The use temperature of mineral wool fiber is lower than rock wool, and it is worse than rock wool in terms of high temperature volume stability.
