As one of Rockwool Board Suppliers, this article talked about the performance of the rock wool board following above.
2. High mechanical strength and low load performance
In Rockwool Board Suppliers，through a reasonable fibrous solution, the upper density of the directional rock wool plate is much higher than the lower layer. By increasing the surface density of the directional rock wool plate, the surface strength of the directional rock wool plate is increased. High -intensity and high -density surface layer improves the overall wind resistance of rock wool and its resistance. It can not only withstand long -term uniform loads, but also convert the load to uniform load, thereby improving the pressure resistance and roof of rock wool and roof roof The rock wool board in the system. At the same time, compared with the hard ordinary rock wool plates, the interior of the directional rock wool board is softer and easier to closely combined with the substrate, avoiding heat loss caused by the air circulation layer.
3. Stretch strength
When selecting insulating materials, the most easily ignored aspect is the performance of resistance. If the impact of compressive strength and load is more reflected in the structure of the roof system, the safety of the roof is inseparable from the tension strength of the rock wool during long -term use. According to the survey, the load level required by general cities in my country is generally about 75 to 90 PSF. If the load is high, the rock wool board needs to have a high tensile strength. The total tensile strength of the directional rockwool board can reach about 10 KPA, and the surface -resistant tensile strength can reach more than 20 kPa, which can meet the requirements of wind load design in any city and region in my country’s Rockwool Board Suppliers .
4. Waterproof performance
The waterproof performance of the directional rock wool plate is mainly achieved by the fiber arrangement structure and the addition of waterproofing agent. The fiber used in rock wool is mineral fiber, and its own water absorption rate is much lower than other fibers. The water -refusted agent is firmly attached to the surface of each rock wool fiber to form a stable and durable mesh structure. Under the action of hydrophobic, water will form water droplets and cannot enter the fiber.
