Glass wool insulation
Wool centrifuge technology is unique, and the molten glass fibrosis be a thermosetting resin-based binder formulation environmentally friendly processing of articles made of a glass fiber diameter of only a few microns are formed elastic glass fiber products, and according to different requirements of customers to select online composite veneer moisture. because of its large number of tiny air voids, it functions as a thermal insulation, sound absorption and safety, is building thermal insulation, sound absorption material.
Glass wool is a glass fiber category, is a synthetic inorganic fibers. Quartz sand, limestone, dolomite and other natural ore as the main raw material, with some soda, borax and other chemicals into the glass melt. Centrifugal glass wool fiber bulkiness internal interleaving, a large number of fine pores, is typical of porous sound-absorbing material having excellent sound absorbing properties, it can be made into wallboard, ceiling, suspended absorber and the like, can absorb a large amount of the room acoustic energy, reduce reverberation time, reduce indoor noise. Glass wool, not only sound absorption characteristics and density related to the thickness, but also with the cover material, structural configuration and other factors. In architectural applications needed taking into account the cost, aesthetics, fire, moisture and many problems, dust, anti-aging and so on.
The physical properties of glass wool: Australia and New Zealand standard AS / NSZ4859.1 certification SGS certification MSDS EU CE certification CE Fire rating certification national standard GB / T13350-2000 scope used in industrial plants, warehouses, public facilities, exhibition centers, shopping malls , as well as heat insulation, acoustic noise kinds of indoor playgrounds, sports stadiums and other buildings.
The main features of glass wool:
1, fire performance: glass wool has the highest fire rating -A level, in full compliance with the relevant national fire safety requirements to ensure the safety of the building, to ensure life and property safety of users. In recent years, several major fires due to faulty insulation materials caused by the state for fire performance of building insulation materials put forward higher requirements.
2, insulation properties: uniform fiber distribution and a more slender fibers, such that the product has a lower thermal conductivity, to ensure superior product performance and other superior insulation performance, ensure long-term thermal insulation effect of the product.
3, environmental performance: inorganic glass wool insulation materials are colorless plate glass and quartz sand as the main raw material made of a green building materials, construction waste can be recycled, in full compliance with environmental requirements.
4, acoustic performance: glass wool internal porous structure, it has excellent sound absorption capability, greatly improve the comfort of the indoor environment.
5, seismic performance: Since the thin and long fibers of glass wool, so that the overall structure of high strength, excellent tensile strength, vibration resistance, long-term use regardless of the installation or are less prone to sag, collapse phenomenon or scattered.
6, chemical properties: glass wool material size stability, less susceptible to high temperature, lightning rain, sunlight, acid and other natural and human factors of destruction and erosion.
7, air permeability: a porous open structure and a special formulation of glass wool, so that it has a greater permeability than other insulation materials, and the interior wall of the moisture helps spread in time, greatly reducing the likelihood of mold growth, help extend the life of the building, but also can improve the comfort of the indoor environment.
8, hydrophobic: curtain with water-repellent wool is highly water-repellent glass wool products, and its water-repellent rate of 99% after the wet from the dry easily, ensure its effective long-term insulation performance.
9, light weight: the glass wool has good sound insulation properties, its low density such that the product can meet the energy requirements of the appropriate specification, glass wool fire insulation material A which most lightweight material, can reduce the building itself bearing also facilitate the construction, improve construction efficiency.
10, installation performance: Since wool fiber diameter and no shot, to avoid scratching or produced construction by itching irritation. At the same time the material soft, easy to cut, arbitrary clipping plane are neat line, can greatly improve the installation efficiency, saving labor costs and shorten the installation period.
Wool main purposes: First, steel wool insulation, advanced centrifugal blowing glass wool production process to produce soft, fine fiber, good elasticity, the waterproof fire wool carpets (folder tendons may Paving aluminum foil veneer), for the steel construction provides an ideal acoustic insulation materials, this product has: acoustic insulation effect, low construction cost, short construction period, non-toxic, does not irritate the skin, to ensure the health of construction workers, form nice features. Second, the adiabatic and soundproof glass wool duct. Wool thermosetting binder is applied, by pressure, heat curing sheets, sound insulation and applied to various specifications of the air duct and the other duct, such as aluminum foil pasted surface veneer, with good insulation effect, light weight, fire retardant, anti-vibration sound absorbing excellent performance.
to sum up:
Centrifugal glass mat, plate, pipe insulation, glass wool, foiling, of hydrophobic, refractory glass wool, glass wool high K and low K value belonging to a category of glass wool wool fiber, a species artificial inorganic fibers. Quartz sand, limestone, dolomite and other natural ore as the main raw material, with some soda, borax and other chemicals into the glass melt. In the molten state, by means of blowing force thrown into floc standard fine fibers, the interchange between the fibers and the fibers are intertwined, showing many fine gaps. Such a gap can be regarded as pores. Thus, glass wool can be regarded as a porous material, having good thermal insulation, sound absorption performance.
