Performance of the folding editor this paragraph
Choose form rich arbitrary by pre cast type processing technology of GRG products can be customized single surface, hyperboloid, three-dimensional covering various geometries, hollowed out pattern, embossed patterns art of arbitrary shape, give full play to the design.
The bending strength of the high strength and light weight GRG products is reached to Mpa20-25 (ASTMD790-2002). Tensile strength reached Mpa8-15 (ASTMD256-2002 test mode, and the standard weight of 6-8mm thick 6-9kg/m2, which can meet the demand of the large plate suspended ceiling, reduce the main weight and component load.
No deformation, no cracking - for advocate the gypsum thermal expansion coefficient is low, wet and dry shrinkage rate is less than 0.01%, make GRG products without environmental cold and hot, dry and wet deformation, stable performance without deformation. Unique cloth fiber processing technology make products not cracking and long service life.
Acoustic reflection properties of GRG has good performance of acoustic reflection, the Tongji acoustic test: 30mm monolithic weight 48kg GRG plate, acoustic reflection coefficient r = 0.97, in line with the requirements of professional acoustic reflection, applicable to the original Grand Theatre, a concert hall acoustics hall.
It is mainly based on thin wall, light intensity, high strength and non combustible (A1 grade fire materials), and can be adjusted to the indoor environment humidity, in order to achieve a comfortable living environment. Its high strength, high hardness and good flexibility, can meet the final be made into any shape, large size and texture effect of the product. No deformation at high temperature for 72 hours at 120.
Standard related folding edit this paragraph
Fire retardant performance of a grade A, according to the GB8624-1997 standard.
The environmental protection performance of the radionuclides limited to a level, according to the GB6566-2001 standard.
GRG - proof performance materials are inorganic materials, no mildew yellowing phenomenon.
Smooth surface, good decorative effect - advanced mold making and releasing process, GRG products smooth surface, high whiteness, does not need to repair and and a variety of coatings and surface decoration material, (wood, fabric, and so on) good bonding, forming excellent decorative effect.
Convenient construction, low loss GRG products are factory prefabricated completed without secondary site processing, installation the use of embedded parts hoisting construction convenient
Core advantage:
1, infinite plasticity:
Products due to the project according to the drawings into the production map, first do the mold, fluid pre cast production, and therefore can be made into any shape. For people requirements for the aesthetic art of the building, the designer of the rich imagination of the innovative design, suffer from does not have a corresponding decorative building materials to help achieve. GRG/C products of arbitrary shape of the plastic for the construction of the shape of the product to achieve seamless docking, is the perfect realization of the dream of the designer, the product is effective for 200 years of quality is the eternal.
2, can breathe, naturally adjust indoor humidity:
GRG plate is a plate with a large number of porous structure. In the natural environment, the porous body can absorb or release water. When the indoor temperature is high, humidity is small, the plate gradually release the micro hole in the water; when the indoor temperature is low, the humidity is large, it will absorb the moisture in the air. This release and respiration form a "breathing" effect. The moisture absorption and release humidity of the cycle changes in the relative temperature of the indoor environment, to create a comfortable environment for the work and living environment.
3, the quality is light, the intensity is high:
The standard thickness of the 9.8KG product plane part is 3.2 to 8.8MM (special requirement can be thickened), weight per square meter is only 4.9 to GRG, which can reduce the weight of the main building and the load. GRG product strength is high, the fracture load is greater than 1200N, more than the international JC/T799-1998 (1996) decorative plaster board fracture load 118N 10 times.
4, the acoustic effect is good:
The test shows that: 4MM thick GRG material, through the 23d\100Hz 27db 500Hz; gas dry weight 1.75, in accordance with the requirements of professional acoustic reflection. After a good design, may constitute a good sound absorption structure, sound insulation, sound-absorbing effect at.
