[China Glass Network] Friends who are familiar with architecture know. Sound insulation cotton is often an essential sound insulation material in home improvement and tooling construction. There are also many types of sound-insulating cotton. Now there are many types on the market that are widely used: glass fiber cotton (referred to as glass wool) and polyester fiber cotton. Both products have their own characteristics, each with its own advantages and disadvantages. If it is used as a soundproofing place for bars ktv, it is recommended to use fiberglass cotton (glass wool).
Glass fiber cotton:
Glass wool is a category of glass fibers and is an artificial inorganic fiber. Glass wool is a material that melts molten glass to form cotton. Its chemical composition is glass. It is an inorganic fiber. It has good shape, small bulk density, thermal conductivity, thermal insulation, good sound absorption and corrosion resistance. Chemical properties are stable.
Glass wool features:
1. Fire resistance and structural shock resistance: It has a high fireproof grade A. The glass wool is thin and long, which makes the overall structural strength high, and has excellent tensile and vibration resistance. It is not easy to sag regardless of installation or long-term use. , scattered or collapsed phenomenon. Fully in line with national requirements.
2, heat preservation, environmental protection: glass wool is made of colorless flat glass and quartz sand as the main raw material of inorganic insulation materials, with superior thermal insulation, for green building materials, construction waste can be recycled, fully in line with environmental protection Claim.
3, chemical, acoustic: glass wool internal porous structure, material size stability, so that it has superior sound absorption, not susceptible to high temperature, lightning rain, sunlight, acid and alkali and other natural and human factors damage and erosion, Greatly improve the comfort of the indoor environment.
4, gas permeability, water repellency: porous open structure, better gas permeability than other insulation materials, help the indoor and wall moisture diffusion in time, reduce the possibility of mold growth, help to extend the life of buildings The curtain wall is made of sorghum glass wool, which has a water-repellent rate of 99%. It is easy to dry after damp, ensuring its long-term effective insulation performance and improving the comfort of the indoor environment.
5. Self-weight: Glass wool has good thermal insulation performance, so that its low-density products can meet the energy-saving requirements of the corresponding specifications. Glass wool is a lighter material among Class A fire-retardant materials, which can alleviate the building itself. Load-bearing can also facilitate construction and improve construction efficiency.
Polyester cotton:
Polyester fiber cotton is also called sound-absorbing cotton. The polyester fiber sound-absorbing cotton fiber produced by melt-blown cotton is relatively small. It is a non-woven fabric composed of 1-4 micron diameter microfiber and 20-30 micrometer diameter short fiber. Cloth material. The blown processing method enables the use of finer fibers to produce a bulky, lightweight product.
The difference between glass wool and polyester cotton:
Glass wool and polyester cotton (polyester fiber-absorbing cotton) have different effects but the sound-absorbing effect is basically the same. It is worth noting that glass fiber is not environmentally friendly and is not easy to construct. Everyone knows that glass fiber is itchy. The polyester fiber has a bad point that the flame retardant effect is poor and flammable. Once the fire is burning than the wood, it can be used in some relatively empty places. If it is similar to the bar ktv entertainment venue, it is recommended not to use it, and it will burn. Producing a lot of smoke can poison people and suffocate.
Glass wool has the function of sound insulation and sound absorption. It is more popular than other sound-absorbing cotton and is widely used in engineering projects. It is currently incomparable to any cotton.
Women's Short Dresses are perfect for those who want to show off their legs and stay cool on a hot day. They are versatile and come in a variety of styles, colors, and patterns, making them an excellent option for all types of occasions.
