GRG

GRG sound absorption board features:

1, grg is not deformed. Since the GRG main material gypsum has no corrosive effect on the glass fiber, and the dry-wet shrinkage rate is less than 0.01%, it can ensure stable performance, durability, no cracking, no deformation, and long service life.

2, light weight. The standard thickness of the flat part of GRG products is 3.2 to 8.8mm (special requirements can be thickened), weight of only 4.9 to 9.8kg per square meter, can reduce the main building weight and component load.

3, high grg strength. Experiments show that the fracture load of GRG products is more than 1200N, which is more than 10 times the fracture load of 118 g of decorative gypsum board in the international JC/T799-1998 (1996).

4, grg will breathe. The GRG board is a board with a large number of microporous structures. In a natural environment, the porous body can absorb or release moisture. When the room temperature is high and the humidity is low, the plate gradually releases the moisture in the micropore; when the indoor temperature is low and the humidity is high, it will absorb the moisture in the air. This release and respiration form the so-called "breathing" effect. This cycle of moisture absorption and release dampness regulates the relative humidity in the room and creates a comfortable microclimate for the working and living environment.

5, grg fire. GRG material belongs to Class A fire-retardant material. In addition to being flame-retardant, GRG material itself can release 15% to 20% of its own weight of water, which can greatly reduce the temperature of the fire surface and reduce fire losses.

6, grg environmental protection. The GRG material has no odor, and the radionuclide limit meets the standard for Class A decorative materials specified in GB6566-2001. And can be recycled, is a green material.

7, grg acoustic effect is good. The test showed that: 4mm thick GRG material, through the loss of 500Hz 23d, 100Hz 27db; air dry weight 1.75, in line with professional acoustic reflection requirements. After a good design, it can form a good sound-absorbing structure to achieve sound insulation and sound absorption.

8, grg processing cycle is short. The demo time of the GRG product is only 30 minutes and the drying time is only 4 hours. Therefore, the construction period can be greatly shortened. GRG is a new type of pre-casting decorative material made of GRG special gypsum as base material and special continuous rigid reinforced glass fiber, which is hand-made on the mold, and has reached the quality of China, the United States, Britain and other countries in terms of comprehensive performance. standard. The surface of the product is smooth and white, and the surface of the material is smooth. The whiteness is over 90%. The high-quality molding surface is conducive to the spraying of any coating. Forms excellent decorative effect, environmental protection and safety without any harmful elements. Product Features: It is mainly made of thin, light and strong, with excellent decorative effect and non-flammability, and can adjust indoor and outdoor humidity so that it can achieve a comfortable living environment. Its high strength, high hardness and good flexibility can meet the needs of products that are finally made into arbitrary shapes, large specifications and texture effects. Store at 120°C for 72 hours without distortion.

This clock material can be made into all kinds of flat plates, various functional products and various artistic shapes, and is the most popular replacement product in the world of architectural decoration materials. Due to the good fire resistance and good acoustic performance of GRG materials, star-rated hotels, office buildings and other indoor luxury decoration.
