Rock wool is a high quality thermal insulation material with low thermal conductivity. Suitable for medium and large diameter pipes; medium and small storage tanks; curved surfaces with small radius of curvature or surface irregularities. Rock wool is made of basalt,After being melted, adopted four-roller centrifugal cotton process to throw the high-temperature basalt-cotton into a 4-7 μm non-continuous fiber. Our rock wool PH value between 7-9, soluble chloride ion content is low, in addition to the non-corrosive steel structure and metal structure, the main features are as follows: Thermal insulation: The thermal conductivity of rockwool at normal temperature (around 25°C) is usually between 0.03 and 0.047W/. Non-combustion : The combustion performance of rock wool products depends on the amount of flammable binders. Rock wool is an inorganic mineral fiber, non-flammable. Sound insulation: rock wool products have excellent sound insulation and sound absorption properties. The mechanism of sound absorption is that this product has a porous structure. When sound waves pass through, friction is generated due to the effect of flow resistance, and part of the sound energy is absorbed by the fibers. Impede the transmission of sound waves. Can be cut according to the security, less security, easy construction Tanks, such as gas and liquid storage, play an important role in every major area of industry. In order to preserve the material and ensure the stability and safety of the production process, it is important to maintain the temperature inside the tank. If the internal temperature of the oil tank is too high, not only the volatile loss of the oil will increase, but also the environmental pollution will be accelerated, and if the temperature is too low, the objects in the tank will become viscous so that the fluidity of the oil will decrease and the oil tank is outdoor for a long time, so when selecting the insulation material, it must have two functions: low thermal conductivity and waterproof performance Rock wool has been tested without asbestos, CFC, HFC, HCFC, and other environmentally harmful substances. It will not be corroded or produce mildew and bacteria. It has excellent performance for the insulation of oil tanks. As a thermal insulation material, rock wool can increase the thermal insulation resistance of the tank walls, reduce the heat transfer coefficient, and reduce the cold/heat transfer through the wall by 70%. This reduces energy loss and saves energy costs.
