How should we choose rock wool insulation board
Clicks: 【489】 Date: [2016/11/4 21:50:59] Rock wool insulation board uses basalt and other natural ore as the main raw materials. After melting, it adopts the international advanced four-roll centrifugal cotton production process to pull the high-temperature solution of basalt cotton rock into discontinuous fibers of 4-7 μm. Add a certain amount of binder, dust-proof oil, and water-repellent agent to the rock wool fiber, and make series of products with different densities according to different uses through processes such as sedimentation, curing, and cutting. Rock wool insulation board products are suitable for thermal insulation and sound insulation of industrial equipment, construction, and ships. So how should we choose rock wool insulation board, what kind of quality is considered high quality, the following editor will explain it for you:
1. It should have low thermal conductivity. Thermal conductivity is an important indicator of the performance of rock wool boards. The smaller the thermal conductivity, the less energy is transmitted through the material, and the better the thermal insulation performance of the thermal rock wool board. (Note: This article is also applicable to vertical rock wool board, waterproof rock wool board, etc.)
2. It should have a high sound absorption coefficient. The sound absorption effect of thermal insulation rock wool board mainly depends on the density of the rock wool board per unit area. The higher the density, the better the sound absorption effect.
3. A good rock wool insulation board should have low hygroscopicity. After most insulation materials absorb water, its insulation effect will be significantly reduced because water has a higher thermal conductivity. Therefore, it is recommended that customers choose waterproof rock wool board.
4, good insulation rock wool board must be able to have a high strength to support its own weight.
