detailed description
1.high strength The breaking load of a 20mm thick GRG product is more than 1200N, that's 10 times above of the 118N breading load in the national standard . According to the "GB/T 3854-2006 testing methode of Fiber reinforced plastic Barcol hardness ",GRG product is more than 50 in this field.
2.Pro-environmental effect GRG product has no odor and its radioactive nuclide quanta conforms to the standard of decoration material of category A as stipulated in GB6566-2001, belonging to a green environmental friendly material.
3.Shape Retention the low thermal expansion parameter and less than 0.1% of dry shrinking rate makes GRG products rather stabilize ,It doesn't wrap ,sag ,or swell due to luctuation of ambient temperature or humidity .
4.Flexibility GRG product has high flexible performance , By using special pre-cast processing technique , it can be moulded into any shapes according to the design ,eg Flat or curved surface ,3D linear ,it can also be designed into artistic patterns like hollowed tracery or relief pattern. Anyway, it can satisfy demands of diversified decorative styles and individuation to show the innovated idea of archiects .
5.Good surface decoration effort GRG product has a smooth and fire surface ,it can achieve designated decorative effect through effective adhension to various paints or coating materials (wood veneer, fabric ,etc.)In addition ,it's resistant to the diluted chemicals ,acid ,alkali ,bleaching agent and solution containing chlorine ,and can withstand exterior corrosion.
6.Fire resistance GRG product is a Non- combustible material .It has passed the tests by National Center for Quality Supervision and Testing of Fire Building Material with a result of A1-grade standard.
7.Moisture Resistance According to relative tests ,it has been proven that the moisture content is less than 0.5%and the maximum water absorption is no more than 10% Thanks to which ,it will not deteriorate when used in damp and humid areas .GRG product doesn't contin any organic element ,which means mildew or yellowing will never happens to it .
8.Insulation ,thermal Insulation Properties GRG product takes advantages of gypsum base ,the micropore structure makes it possible to adjust its water content automatically ,which can help in improving the performance of thermal insulation .It complies with ASTM D696:2003 ,"Tests for thermal transmission and expansion '.This advantage can balance interior temperature and humidity in creating an comfortable interior Environment.
9.Short Process Cycle The demand of GRG product takes only 1 hour .Through special handing,the drying process can be shorten to 4-8 hours .Thus a short process cycle is ensured.
10.Acoustic Performance Sounds spread easily in spacious space ,but it's also easy to control the transmission through partial adoption of high density materials. The normal density of GRG products which over 1800kg/m3 with a high performance in reflecting sonic waves.According to "code for measurement of sound-absorbing coefficient in reverberation room " by institute it has been proven that the sound reflection coefficient of a 25mm thick GRG product is more than 0.97, which complies with reflection requirements of professional acoustics. The products can be designed into and modeling used in various large places needing the acoustic effect such as the concert halls and theaters.
11. Easy Construction Through imagination work of designs,GRG product can be freely modeled and produced in large piece .The hoisting and splicing technique makes an outstanding process performance on site and makes the installation work quick and flexible . GRG products can be seamlessly assembled in spacious areas and further achieve a perfect decorative effect.
