  Sound insulation cotton is a new type of sound insulation material commonly used in buildings now. There are many types, such as rock wool, glass wool, EPS and other materials, all of which have the effect of sound insulation and sound absorption. So is the sound insulation cotton rock wool? Take a look.

  Rock wool is made of basalt and other natural ores as the main raw materials, melted into fibers at high temperature, added with an appropriate amount of binder, and solidified. Thermal insulation and sound insulation of roofs, fire and noise reduction of building partitions, firewalls, fire doors and elevator shafts.

  There are many kinds of sound insulation materials commonly used in modern buildings, the common ones are glass wool, rock wool, sponge, polyester fiber sound-absorbing cotton, rubber and plastic. Different use scenarios require different sound insulation cotton, and the material of the sound insulation cotton must be carefully considered before use. The sound insulation cotton materials used for water pipes include polyester fiber cotton, polyurethane surface, glass fiber cotton and rock wool. For the thermal insulation of equipment, the commonly used thermal insulation cotton materials also include glass wool and rock wool, so thermal insulation cotton and sound insulation cotton are the same in material.

  For rock wool pipe and rubber-plastic insulation pipe, it is recommended that you use rubber-plastic insulation pipe, because it is more moisture-resistant than rock wool pipe, and the sound insulation is more durable. However, rock wool is a grade A non-combustible material, which is more in line with national fire protection standards and can be selected according to the fire protection requirements of buildings. Uetersen rock wool has high compressive strength and point load, which can maintain stable thermal insulation, sound insulation and noise reduction. Both glass wool and rock wool are made of brittle fibers that can easily puncture the skin and cause skin irritation. And over time, the product will be pulverized, and the dust generated will cause respiratory allergies, so personal protection work needs to be done during installation.

  To judge the quality and sound insulation effect of a piece of sound insulation cotton, it mainly depends on the density and thickness. For sound absorption, it mainly depends on the thickness of the ducts and fiber spaces. For keeping warm, it mainly depends on the heat resistance and thickness of the insulation layer. Among them, the glass sound insulation cotton has the characteristics of environmental protection, non-toxicity, corrosion resistance, high temperature hot melt sterilization and bacteriostatic treatment, and the rubber sound insulation cotton is the same as the glass sound insulation cotton. The price is very high, and ordinary families can choose to install it by themselves.
