Xi'an Dazhongliang Building Materials Co., Ltd ， It's a family ***Production GRG&GRC products (*** Glass Fiber reinforced Gypsum Series products/* * * glass fiber reinforced cement Composite plate series products). The company is committed to the in-depth design, material production and engineering construction of indoor and outdoor GRG&GRC. Large, medium and beautiful It is the representative of the national technical level. Most of its employees are elites in the industry. It has rich experience in the design and construction of large-scale landmark buildings at home and abroad. Our team members have participated in the design, production and project construction. Registered capital of the company Five million The company and factory are both located in Xi'an, Shaanxi Province, covering an area of more than 10000 square meters, and can * * * undertake the in-depth design, material production, installation and construction of large-scale projects 。
GRG product is a kind of high-quality natural improved gypsum as the base material, with gypsum added*** Reinforced glass Fiber and environmental micro additives, made of pre cast new decorative materials. This material can be made into various flat panels, various functional products and various artistic shapes. It is currently the top architectural decoration material industry of * * * very Popular updated products. According to our research and practice, as well as relevant foreign scientific research literature, GRG material, as a new type of updated building decoration material, has the following * * * advantages and characteristics:
1. No deformation. Since the GRG main material gypsum has no corrosive effect on the glass fiber, and the dry and wet shrinkage rate is less than 0.01%, it can ensure that the product has stable performance, durability, no cracking, no deformation, and long service life.
2. Light weight. The standard thickness of GRG product plane part is 3.2 * * * 8.8mm (thickening is allowed for special requirements), and the weight per square meter is only 4.9 * * * 9.8kg, which can reduce the weight of main buildings and component loads.
3. High strength. The experiment shows that the breaking load of GRG product is more than 1200N, exceeding * * * JC/T799-1998 (1996) decoration plasterboard 10 times the breaking load of 118N.
4. Can breathe. GRG plate is a kind of plate with a large number of micropores. In the natural environment, the porous body can absorb or 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 humidity is 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 protection. GRG material belongs to Class A1 fireproof material. In case of fire, in addition to being flame retardant, it can also release moisture equivalent to 15% * * * 20% of its own weight, which can significantly reduce the temperature of the fire surface and reduce fire losses.
6. Environmental protection. GRG materials have no smell, and the limit of radionuclides meets the standard of Class A decorative materials specified in GB6566-2001. It can also be used for * * *, and is a green environmental protection material.
7. Good acoustic effect. The test shows that the transmission loss of 4mm thick GRG material is 500Hz 23db, 100Hz 27db; The air dry specific gravity is 1.75, meeting the acoustic reflection requirements of * * *. Through good modeling design, a sound absorption structure can be formed to achieve sound insulation and absorption.
8. The processing cycle is short. The demoulding time of GRG products is only 30 minutes, and the drying time is only 4 hours. Therefore, 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 material surface is smooth and delicate. The whiteness reaches more than 85%, and can be well bonded with various paints and finishing materials to form a good decorative effect
