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 ,m 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 25C) 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

glasswool board besides heat insulation and thermal insulation, it has other advantages such as excellent damping and sound absorption, especially for intermediate and low frequency and all kinds of noise concussion, noise reduction and working environment improvement. The materials can be cut at random according to the construction requirement. It is mainly used on the following aspects: rooms of buildings, sound reduction system, mean of communication, refrigeration equipments, damping, and sound absorption and noise reduction of domestic electric appliance, which has a satisfactory effect. complete Glasswool insulation board is made by adopting unique centrifugal technology and adding environmental adhesives of thermosetting resins-based into molten glass fibrosis. It is a kind of elastic glass fiber product made of glass fiber with diameter of only a few microns, and we can also choose moisture-proof facing on-line compound according to customers' requirements. Because of a large number of tiny air interspaces, it has the functions of heat insulation, sound absorption, safe guarding and etc, so it is the best materials of heat insulation and sound absorption in construction. Glasswool insulation board production lines range from 5 to 700 tons/day capacity (100,000 to 1,500,000 tons/year), and are fully automated thanks to PLC and Scada systems. Distinctive Advantages of Glasswool Insulation Board: Sound absorption and noise reduction. Easy for construction; cutting at will. Grade A1 fireproof. Low moisture absorption; stable physical properties. Strong vibration resistance and high durability.

Phosphate Rock is the raw material to manufacture most commercial phosphate fertilizers. In its unprocessed state, phosphate rock is not suitable for direct application. The process begins by grinding rock phosphate to a fine material. Potash is also fed together with super phosphate to obtain various grades of fertilizers.

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.

Glass wool is manufactured with quartz sand,feldspar,sodium silicate and boric acid as main Ingredients ,which are melted under high temperature and made into fibers thinner than 6um. We can offer Glass wool batts,glass wool blanket,glass wool board and glass wool pipe. Rock Wool is produced by melting mix of basalt,limestone&coke in a special vertical furnace at very high temperature(about1500°C).Then the molten rock is made into thin fibers through a high speed centrifugal machine. After adding certain amount of binder,dust proof oil,silicon oil and mechanical operations,rock wool fibers are then processed to be the final desired product with specified physical and chemical Properties and specifications.
