  In recent days, the temperature has continued to be very hot all over the country. In the event of rain, in a humid environment, if the waterproof rock wool board we transport or store is accidentally exposed to the rain, can it still be used?

  Ordinary rock wool board is mainly made of basalt and other natural ores as raw materials, which are made into fibers by special processes such as high temperature melting, and then add an appropriate amount of binder, and are solidified and processed into a yellow solid plate-like material. Due to the structural properties of natural materials, rock wool board has the properties of heat insulation, fire prevention and water repellency, sound absorption and noise reduction. Therefore, it is widely used in various industrial boilers and equipment pipes such as petroleum, chemical industry, metallurgy, shipbuilding, textile, etc. in today's market.


  The waterproof rock wool board is not absorbent and can be used normally after rain. The waterproof performance of ordinary rock wool board is not good, and it may be damaged in a humid environment. Waterproof rock wool board is produced by adding water repellent in the process of producing rock wool board. It has good waterproof function and can be used in areas that require good waterproof performance such as building exterior walls. Uetersen waterproof rock wool board has a water repellency rate of ≥ 99%, which can well meet the function of waterproof and moisture-proof, and ensure consistent performance in wet or watery environments.

  But even waterproof rock wool board can't be exposed to rain all the time. Long-term use in a humid environment will still damage the rock wool board, which will bring great safety hazards to subsequent construction. Therefore, the rock wool boards stacked in the construction site warehouse should be waterproofed in time and transferred to a place without rain. Don't let it be exposed to the rain all the time, let alone soak in a puddle.
