The Sandwich Board Has Sound Insulation Performance

Jul 12, 2017

Sandwich board dedicated rock wool board, building rock wool board, fireproof Black cotton Board and other products professional enterprise, has a complete, scientific quality management system, equipped with a sound testing equipment, professional, dedicated service team, Sandwich Panel welcome friends from all walks of life business negotiations. In recent years, the rock wool board this kind of insulating material in the market already is a kind of demand-tight condition, but why this kind of circumstance, the reason may appear in these aspects.

When the sandwich board special Rock wool Board into the decorative materials, the most important is the use of external wall insulation, roof insulation, Sandwich Panel the implementation of the relevant national standards.

From a lot of sound insulation materials, believe that the use of construction sites as temporary housing for the sandwich board dedicated rock wool board, is a very good sound insulation material. From the material production of raw materials, mainly through the rock wool, slag cotton, such as a number of materials made. Because it is able to bring a good sound insulation and sound absorption effect can be better in the use of the process to reflect such a sound performance.

In the principle of production, Sandwich Panel the absorption of the Special rock Wool Board for the sandwich board is mainly in time through the porous structure, then transmit sound waves, but from this structure, the sound waves inside the loop, it is very easy to cause a certain obstacle, then in this case, basically the sound wave is absorbed by the fiber of this material, can better hinder the process of such sound waves.

Classification of Sandwich panels

1. There are six types of core materials:

Polystyrene Sandwich Panel is EPS sandwich panel (currently on the market, Sandwich Panel the most widely used varieties);

Extruded Polystyrene Sandwich panel is XPS sandwich panel;

Rigid Polyurethane Sandwich panel is PU sandwich plate;

Three polyester sandwich plate is PIR sandwich plate;

Phenolic sandwich panel is PF sandwich plate;

The core board of rock wool is RW sandwich board.

Foam Metal Sandwich Panel

2. There are two types of panels:

Metal panels and Non-metallic panels two. Metal panel is easy to process, can be made of various shapes, but some occasions non-metallic panels have a metal panel of the role, Sandwich Panel such as corrosion resistance, impact resistance and so on.

Characteristics of Sandwich Panel:

1, light weight of less than 24kg per square metre, can fully reduce the cost of construction.

2, the installation of fast weight, plug, installation and can be free to cut the characteristics of the installation to determine its simplicity, can improve efficiency, save time.

3, fireproof, color steel composite Core board of the surface materials and insulation materials for non-flammable or refractory materials, can meet the requirements of fire code.

4, refractory, the special coating treatment of color plate to protect the new 10-15 years, every 10 years after spraying anti-corrosion coatings, Sandwich Panel plate life expectancy of more than 35 years

5, beautiful, pressed steel plate clear lines of up to dozens of kinds of color, can match any style of building needs

6, thermal insulation commonly used insulation materials are: rock wool, glass fiber cotton, polystyrene, polyurethane, etc., low thermal conductivity, has a good thermal insulation effect.

7, environmental protection noise, composite board noise intensity of up to 40-50 decibels, is a very effective sound insulation materials.

8, plastic pressure-type steel plate can be arbitrarily cut, enough to meet the needs of special design.

9, high-strength use of HIGH-STRENGTH steel plate as the base material, tensile strength 5600 (kg/cm2), coupled with the most advanced design and roll molding, with excellent structural characteristics
