1) Rockwool products can be used in the construction of steel structures, concrete and masonry roofs, exterior walls, insulation of partition walls and curtain walls, and high temperature pipe insulation.
2) Moisture has very easy migration characteristics in mineral wool insulation materials, and the inherent looseness of its products leads to high air permeability. Therefore, when using mineral wool products, moisture migration, air permeability and compressibility should be considered. Sex and durability.
3) For the exposed ventilation roof of the insulation layer and the wall with cavity on both sides of the insulation layer, reliable anti-infiltration measures should be taken to ensure that the insulation performance will not be greatly reduced.
4) Because water has a very easy migration property in mineral wool insulation materials, liquid water will be quickly discharged from the bottom of vertical building components (such as external walls), and non-permanent moisture will not significantly affect the insulation performance of the components. . However, horizontal building components such as flat roofs may have an impact.
5) In the usual density range, the thermal conductivity of mineral wool products does not change substantially with density. However, the thermal resistance of mineral wool products is proportional to its thickness. It can be seen that the compression caused by the load, the compression creep under long-term load, and the sinking under long-term use will lead to a decrease in thermal resistance.
6) The durability of mineral wool products mainly involves compression creep, subsidence and moisture deterioration, and these changes will directly affect their insulation properties.
7) Rock wool products have low soluble chloride ion content and no corrosive effect on steel components (including austenitic stainless steel).
8) Rock wool products may shrink and deform at high temperatures. When the rock wool products with low density are used for a long time or when there is high frequency and low amplitude vibration, thickness subsidence may occur.
9) The tensile strength, anti-collapse performance and thermal stability of the pendulum rock wool product are better than the sedimentation rock wool products.
10) The action of heat and water vapor may have a detrimental effect on inorganic mineral fibers. Long-term exposure of slag wool and rock wool to high temperature and high humidity environment may lead to fiber breakage and heat preservation performance.
