1. Light weight, high strength, no deformation. Since its main material gypsum has no corrosive effect on glass fiber, and its dry and wet shrinkage rate is less than 0.01%, it can ensure stable performance, durability, no cracking, no deformation, and long service life of the product.
2. Light weight (specific gravity 1.6-1.8). The standard thickness of GRG product plane part is 4mm to 20mm (it can be thickened in case of special requirements), and the weight of each square meter of material is only 5 to 10kg, which can reduce the weight of main buildings and component loads.
3. High strength. Experiments show that G RG. The breaking load of the product is more than 1200N, which is 10 times of the breaking load of 118N of international JC/T799-1988 (1996) decorative gypsum board.
4. Can breathe. GRG is a kind of plate with a large number of microporous structures. In the natural environment, the porous body can release water. When the indoor temperature is high and the humidity is low, the board gradually releases the moisture in the micropores; When the indoor temperature is low and high, it will absorb moisture in the air. This release and respiration form the so-called "breathing" effect. This cycle of moisture absorption and release plays a role in regulating the indoor relative humidity, creating a comfortable microclimate for the working and living environment.
5. Fire prevention. GRG. material belongs to Class I fireproof material. In addition to being flame retardant, it can also release moisture equivalent to 15% to 20% of its own weight in case of fire, which can significantly reduce the temperature of the fire surface and reduce fire losses.
6. Environmental protection. GRG. The material has no smell, and the limit of radionuclides meets the standard of Class A decorative materials specified in GB6566-2001. And it can be recycled, which is a green environmental protection material.
7. Good acoustic effect. Test surface: 4mm thick GRG material, transmission loss 500Hz23db, 100Hz27db; Air dry specific gravity is 1.75, meeting professional acoustic reflection requirements. Through good modeling design, a sound absorption structure can be formed to achieve sound insulation and absorption.
8. Short processing cycle. The demoulding time of GRG products is only 120 minutes, and the drying time is only eight hours, so the construction period can be greatly shortened.
9. Convenient construction. GRG can be shaped arbitrarily according to the designer's design, and can be produced and divided in large blocks. Good field processing performance, rapid and flexible installation, large area seamless and tight assembly, forming a complete shape. Especially for the details of openings, arcs, corners, etc., it can ensure that there is no error.
10. The surface of the material is smooth and smooth, with a whiteness of more than 90%, and can be well bonded with various paints and finishing materials to form an excellent decorative effect.
