Centrifugal glass wool is a plate shaped product with unique centrifugal technology, which will melt glass fibrosis and solidify by adding environmentally friendly formula binder based on thermosetting resin. Slender glass fiber low thermal conductivity, can be very good air, so as to play the role of heat preservation and insulation, sound absorption noise reduction and safety protection, its surface can also paste aluminum foil or PVC film.
It is widely used in heat preservation, heat insulation and noise reduction of equipment such as boiler, flue, hot air duct, dust collector, reactor etc., all kinds of products have obvious advantages and have higher cost performance because of light weight, durable and excellent heat preservation performance.
Glass wool is an artificial inorganic fiber with a diameter of less than 6 microns made of lime, quartz powder and other minerals melted in a furnace, centrifuged or sprayed at high speed, and then made into various products by molding equipment.
The product has long and thin glass fiber, low thermal conductivity; Excellent sound absorption and noise reduction, can effectively prevent sound transmission; Grade A non-combustible material, high fire resistance; Strong hydrophobicity, excellent mildew resistance; Stable chemical properties, aging resistance, corrosion resistance; Light material, simple construction; Low cost price, cost-effective.
It is suitable for heat preservation, heat insulation and sound absorption materials in construction, chemical industry, petroleum, electric power, refrigeration, ships and many other fields.
It is well known that glass wool blankets have insulation function and can be used in building interiors. At the same time because of its structure characteristics have obvious sound absorption effect, is conducive to noise reduction, can be used for noise reduction systems, vehicles, refrigeration equipment, household appliances, shock absorption, noise reduction processing, to provide environmental protection life. This kind of material can be cut at will. The glass cotton felt with aluminum foil veneer has strong heat radiation resistance and is the lining material of high temperature workshop.
Is glass wool insulation building materials industry, has a good shape, small volume density, thermal conductivity 彽, thermal insulation, corrosion resistance, stable chemical performance advantages, such as glass cotton and a small feature is actually sound absorption performance is very good, also is pretty good yo, on the sound insulation effect to play the effect of heat preservation and sound insulation, kill two birds with one stone.
Influence of thickness on sound-absorbing characteristics:
The thicker the thickness of glass wool, the better the sound absorption effect, glass wool thick penetration will be very small, the sound absorption effect is very good.
Density and air retention resistance of glass wool:
Air flow resistance is an important factor affecting the sound absorption performance of centrifugal glass wool. The smaller the flow resistance is, the material is sparse, the air vibration is easy to pass through, and the sound absorption performance decreases. The greater the flow resistance, the material is dense, air vibration is difficult to enter, sound absorption performance is also reduced. So in the choice of insulation building materials at the same time also pay attention to the sound absorption effect.
