ROCK WOOL
Rock wool is produced from melting stone (diabase, dolerite) at about 1500 C, where the heated mass is hurled out from a wheel or disk and thus creates fibers.
Specially designed for brake pads & brake linings. 1) Mineral fiber has Good wear resistance and high thermal stability by high temperature melting. Offered by Tangshan Hanwei. 2)� This kind of friction fiber has Low agglomeration that due to water washing. 3) Good reinforcing effect and well-proportioned dispersion. 4) No pollution and biodegradability, high-quality reinforcing material to non-asbestos friction materials.
Rock wool board insulation is made of select fine basalt as the major materials which is pulled into 4-7µ non-continuous fibers after melted by adopting advanced international four-roller centrifugal cotton-making procedures and adding a certain of adhesives, dust laying oil and water repellent into rock wool fibers. It can be made into products series with different density according to various uses through the technology of sedimentation, solidify, cutting and etc. Dimension: 1200mm*600mm, 1200mm*630mm Thickness: 30-150mm Density: 60-200kg/m3 Petrochemical industry -- heat insulation and sound absorption of equipments for petroleum industry, power industry and chemical industry. Construction industry -- heat insulation and sound absorption of partition, curtain wall, roofs and fences for construction. Mining industry -- heat preservation and fireproof for industrial kiln, oven, large-caliber storage tank and shipping.
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.
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.
Worsted wool fabric is primarily used in tailored garments like suits, distinguishing it from woolen wool, which is typically used for knitted items like sweaters. The key characteristic of worsted yarn is its straight, parallel fibers. This sets it apart from woolen yarns, where the wool's natural crimp is retained. In the production of worsted yarns, the crimp is removed during the spinning process, resulting in a smoother, finer texture. We produce worsted wool from Merino sheep, renowned for their coats that yield the finest and softest wool available. Additional Details: All of our yarns are standard, but we are open to providing customized yarn production and services. Yarns can be supplied on 4*20â?? plastic and paper cones, PSDP, or 3*30â?? paper cones. For knitting yarns, we can also provide yarns in hank form, in addition to the above packaging. The standard package weight is 1.5 kg, but we can accommodate customized package dimensions upon request. Typically, yarns are supplied on 4*20â?? plastic cones, though we can also provide plastic cones for packaging as required.
Rock wool products are made from natural mineral wool such as basalt and dolomite. The natural rock are melted into melts in cupola at a very high temperature about 1500The highest application temperature is 700 it has characters : sound insualtion ,fireproof ,waterproof and so on. It always used in the construction sound insulation wall,roof , industrial furnace,oven,heat -treating equipment,storage tank and so on.It has characters such as: Superior Fire Resistance Rock wool board is non-combustible, not burn,not smoke and can arrived Class A fire rating and it also has heat preservation. Its highest working temperature is 750 Good Water reprellence: Rock wool products greatly reduced by adding special silicone emulsion water repellent agent, thus ensuring the quality requirement for external wall insulation system. Hydrophobic rate is 99%. Environment Friendly Free from asbestos, CFCS, HFC, HCFCS and other harmful substances to the environment; our rock wool adopt the resin binder. Do not release any toxic gas at high temperature. Construction Application Rock wool was used for building materials , and steel structure insulation soundproof and fireproof used for wall and roof of house Heat preservation for steel structure building For indoor partition wall , Train compartment . Rock wool used for industrial furnace, oven, heat-treating equipment, storage tank, storage groove. power house, flue, petrifaction and oil refining equipment and all kinds of keeping-warm and heat insulation pipelines.
