National standard high temperature glass wool insulation board
Glass wool is a product made of centrifugal glass wool felt which is processed by Owens Corning (OC) proprietary patented centrifugal technology, which is made of molten glass fiber and thermosetting resin. An elastic felt body made of glass fiber with a diameter of only a few microns, and can be combined with different moisture-proof veneers according to the requirements of use. It has a large number of tiny air pores, which makes it play the role of thermal insulation, sound absorption and noise reduction and safety protection. It is a material for thermal insulation, sound absorption and noise reduction of steel structure buildings.
Glass wool is a category of glass fibers and is an artificial inorganic fiber. Natural minerals such as quartz sand, limestone and dolomite are used as the main raw materials, and some raw materials such as soda ash and borax are melted into glass. In the melted state, the flocculent fine fibers are blown by an external force, and the fibers and the fibers are three-dimensionally intersected and entangled with each other to exhibit many fine gaps. This gap can be seen as a void. Therefore, glass wool can be regarded as a porous material, and has good heat insulation and sound absorption properties.
Main feature
1 fire performance glass wool has a high fire rating of zui - fully in line with national fire protection requirements, to ensure the safety of the building, to ensure the safety of life and property of users. In recent years, due to several major fires caused by unqualified insulation materials, the state has put forward higher requirements for the fire performance of building insulation materials.
2 Insulation performance Glass wool, uniform fiber distribution and more slender fiber make the product have lower thermal conductivity, ensuring superior thermal insulation performance and other superior performance indicators, ensuring long-term insulation effect of the product.
3Environmental performance glass wool is an inorganic insulation material made of colorless flat glass and quartz sand as the main raw materials. It is a green building material product, and construction waste can be recycled, which fully meets environmental protection requirements.
4 Acoustic properties The internal porous structure of the glass wool makes it have superior sound absorption capacity and greatly improves the comfort of the indoor environment.
5Structural performance of the glass wool Due to the thin and long fiber, the overall structural strength is high, and the tensile and anti-vibration properties are superior. It is not easy to sag, scatter or collapse during installation or long-term use.
6 Chemical properties Glass wool materials have good dimensional stability and are not susceptible to damage and erosion by natural and human factors such as high temperature, lightning, sunlight, acid and alkali.
7 Breathable performance The porous open structure of glass wool and its special formulation make it better breathability than other insulation materials, which helps the moisture in the room and wall to spread in time, greatly reducing the possibility of mold growth and helping. To extend the life of the building, it can also improve the comfort of the indoor environment.
8 Water-based curtain wall is made of sorghum glass wool. Its water-repellent rate is as high as 99%. It is easy to dry after damp, ensuring its long-term effective insulation performance.
9 self-weight light glass wool has good thermal insulation performance, so that its low-density products can meet the energy-saving requirements of the corresponding specifications. Corning glass wool is a lightweight material in the fire-proof insulation material, which can reduce the weight of the building itself. It can facilitate construction and improve construction efficiency.
10 Construction and installation performance Glass wool is thin and does not contain slag balls, avoiding scratches or itching irritation to the builder. At the same time, the material is soft and easy to cut, and any cutting surface is neat and uniform, which can greatly improve the installation efficiency, save labor costs and shorten the installation period.
The centrifugal glass wool is a porous sound absorbing material and has good sound absorption performance. The reason why centrifugal glass wool can absorb sound is not because of the rough surface, but because of the large number of tiny pores and pores that communicate inside and outside. When sound waves are incident on the centrifugal glass wool, sound waves can enter the inside of the material along the pores, causing vibration of air molecules in the gap. Due to the viscous resistance of the air and the friction between the air molecules and the pore walls, the acoustic energy is converted into heat energy and lost.
Sound absorption performance Centrifugal glass wool has good sound absorption performance for high frequency in sound. The main factors affecting the sound absorption performance of centrifugal glass wool are thickness, density and air flow resistance. Density is the weight of material per cubic meter. The air flow resistance is the ratio of the air pressure to the air flow rate on both sides of the material per unit thickness. Air flow resistance is an important factor affecting the sound absorption performance of centrifugal glass wool. The flow resistance is too small, indicating that the material is sparse, the air vibration is easy to pass through, and the sound absorption performance is degraded; the flow resistance is too large, indicating that the material is dense, the air vibration is difficult to be introduced, and the sound absorption performance is also lowered. For centrifugal glass wool, the sound absorption performance exists in the area where the zui flow resistance is located: Langfang City, Hebei Province.
