High-strength rock wool board performance
Rock wool is an inorganic fiber made of natural rock such as basalt, gabbro, dolomite, iron ore, bauxite, etc., which is made of high-temperature melting and fibration.
Slag wool is an inorganic fiber made from industrial slag such as blast furnace slag, phosphorus slag, fly ash, etc., which is remelted and fiberized. These two kinds of fibers can be processed into boards, tubes, felts, belts, paper and other products. They should be used for insulation, fire prevention, thermal insulation, sound absorption, and earthquake resistance in construction and industrial equipment, pipelines, and kilns.
1. Insulation performance: Good thermal insulation properties are the basic characteristics of rock wool and slag wool products. The thermal conductivity of rock wool is usually between 0.03 and 0.047 W/(moK) at room temperature (around 25°C).
2. Combustion performance: The combustion performance of rock wool and slag wool products depends on the amount of combustible adhesive. Rock wool, slag wool itself is inorganic mineral fiber, non-flammable, in the process of processing into products, sometimes adding organic binders or additives, these products will have a certain impact on the combustion performance.
3, sound insulation properties: Rock wool, slag wool products have excellent sound insulation and sound absorption properties, the sound absorption mechanism is that this product has a porous structure, when the sound wave passes, due to the role of flow resistance friction, so that the sound energy One part is absorbed by the fiber, which hinders the transmission of sound waves.
Rock wool board application:
Rock wool has been widely used in construction and industrial equipment, pipelines, kilns for heat insulation, fire protection, sound absorption, seismic, metallurgy, machinery, building materials, petroleum, and chemical industries since the 1970s. The best insulation material for rock wool thermal insulation products.
In the process of implementing the external thermal insulation technology of rock wool board, the rock wool board external thermal insulation wall is composed of a functional wall structure layer, thermal insulation layer, protective layer and decorative layer, and the external wall thermal insulation implementation technology One is rock wool board insulation wall building. Dealing with the relationship between these four levels is the key to making the external thermal insulation wall a key technology.
To deal with the relationship between the components of the rock wool board outer wall insulation wall, it is necessary to have a clear grasp of the connection between the components and common problems. Among them, the insulation layer, the protective layer and the structural layer are connected in the following ways: the connecting rod bracket, the oblique connecting rod bracket, the long screw, and the adhesive. Each of the above four connection methods has its own characteristics. However, in comparison, the first three types of construction are more troublesome and the fourth one involves problems such as adhesive strength and durability. Therefore, the following four more simple solutions are recommended: Expansion bolt scheme; pre-embedded steel or plastic rib scheme and adhesive and nail combination scheme.
Type: Ferro Silicon Magnesium, Rare earth Ferro Silicon Magnesium Size: 1-6mm, 2-12mm, 5-30mm or as per demand
Packing: 25kgs waterproof bags inside 1mt big bag or as per demand
Application: The raw materials used in the production of the nodulizer are all deoxidized and de-rusted, and are produced through special smelting equipment, The melting of the alloys is carried out in a protective atmosphere so that the MgO content in the nodulizer is extremely low, and the MgO content in the RE Mg nodularizer can be stably controlled below 0.8%, or MgO content controlled below 0.5% according to customer demand. The MgO content in nickel-magnesium and copper-magnesium alloy nodulizer can be controlled at 2.5% or less.
