Glass wool roll felt can achieve the effect of heat preservation and noise reduction in steel structure construction

The steel structure glass wool felt insulation material is a filamentary material made of fiberized and sprayed thermosetting resin in the centrifugal blowing process of glass molten state. It has the advantages of non-combustibility, non-toxicity, corrosion resistance, low density, low thermal conductivity, high chemical stability, low moisture absorption rate and good hydrophobicity. use.

It is widely used in thermal insulation, sound absorption and noise reduction in the fields of construction, chemical industry, electronics, electric power, metallurgy, energy, transportation, etc., and the effect is very significant. Glass wool is the main raw material for glass-forming silicate minerals.

The glass wool composite board has good noise and vibration reduction characteristics by melting and applying a certain amount of centrifugal glass wool, so the products of this material can be used in many ranges, and this effect can be reflected in different application.

1. Noise reduction

Application According to this centrifugal glass wool has the characteristics of noise reduction, it can be used in some building materials, such as interior decoration materials, with a certain partition, so you can re-reduce the impact of noise in the space and make our living environment more Silent. This app, one of its products, is very important to us.

Nowadays, many equipments in startup and normal operation will have different degrees of vibration. Equipment that can be affected by processing and production can be operated with this material damping device to make our needs more consistent.

What will happen after the centrifugal glass wool is superimposed? How will these properties affect the stack? Due to the thermal insulation performance of centrifugal glass wool, and sound insulation, then what changes between these two?

Because the centrifugal glass wool has thermal insulation properties, when it will use the stack, it is equivalent to doubling or even several times its thickness. If it is heated, when it is hot, it is very hot if you use a layer of cloth, and many are several times. Isn't the layer hot? So this performance will increase.

2. Noise

The relationship between the thickness and density of the centrifugal glass wool for noise reduction, so if it is equivalent to superimposed use, increase the thickness of the centrifugal glass wool, so when the air passes through the sound and noise, the increase in the thickness will decrease, which is equivalent to better sound absorption and noise reduction.

Glass inorganic fibers. According to the production process, it can be divided into centrifugal glass wool injection and flame sprayed glass wool; according to the fiber diameter, it can be divided into insulating glass wool and ultra-fine glass wool; The production of glass wool and its products by jet technology is called centrifugal jet glass fiber (centrifugal cotton for short). This is the process by Saint-Gobain.

With advanced technology, it can continuously produce various products and realize the realization of automatic control technology operation. The price of glass wool composite panels for exterior walls saves energy compared with the flame spraying method. Now more than the total amount of glass wool produced in the world is produced by centrifugation.

Corrosion-resistant high-insulation high-glass wool material According to the physical principle, the thermal conductivity of the gas is small, and there are many pores in the excellent thermal material. The large amount of gas produced by the glass fiber cotton factory and the irregular arrangement of fibers are excellent in sound insulation, heat insulation, sound absorption, heat insulation and thermal conductivity.
